2.2.2.1 Descriptions of Facilities

2.2.2.1.1 Industries

The section of the Mississippi River between Bat on Rouge and New Orleans is a highly industrialized region. The proximity of oil and gas fields in coastal Louisiana and the

WSES-FSAR-UNIT-32.2-2proximity of the Mississippi River, a major shipping route, makes this area an ideal location for a widevariety of industries. Between Baton Rouge and New Orleans there are approximately 63 industrial facilities located on or near the river(3). Of these, approximately 52 are involved in refining oil and gas orin the production of diversified chemical products.Table 2.2-1 provides a listing of the 15 industrial facilities within five miles of the site and shows the majorproducts they produce, employment and their distance and direction from the Reactor Building. All of the companies listed in Table 2.2-1 with the exception of Louisiana Power & Light and the Union Pacific Railroad are involved in the production or storage of petrochemical and chemical products. The closest industrial property to Waterford 3 is Agrico Chemicals Co. (formerly Beker Industries) approximately 0.6 miles east of the site. Agrico, which has a total employment of 210 people, produces high analysis fertilizer materials such as diammonium phosphate and wet-process phosphoric acid. Occidental Chemical Company, approximately 0.8 miles to the east of the site, produces caustic sodas, chlorine and various chlorine based products and has an approximate total productive capacity of 1.12 billion pounds of chlorine annually(4). Union Carbide Chemical and Plastics Plant approximately 1.2 miles to the east,employs 1,497 people and is the largest chemical plant within five miles of the site. This plant manufactures chemicals of the intermediate variety and has an approximate total productive capacity of 2.5 billion pounds of chemicals a year(4). Shell Chemical Company, 2.5 miles east-northeast of the siteand Shell Oil Company, 3.5 miles east-northeast of the site have a combined total employment of 1,406 and a combined productive capacity of 235 thousand barrels of oil per day, 1,620 million pounds of petrochemicals per year and 1,200 million pounds of chemicals a year(4). Other industries in the area areclassified in Table 2.2-1. (This is historical data, published in May, 1977).2.2.2.1.2Transportation Facilities Transportation facilities and routes within the vicinity of Waterford 3 are shown in Figures 2.2-2 and 2.1-31.a)RoadsThe closest highway to Waterford 3 is Louisiana State Highway 18 (LA 18)approximately 600 ft. northeast of the Reactor Building. In 1976, the average daily traffic (ADT) count for LA 18 just west of Hahnville was 4,905(5) (see Figure 2.2-2). In June of 1973, thesection of LA 18 between Hahnville and Edgard, (12.3 miles) was projected to have a 1997 traffic volume of 5,950(5).Approximately one mile to the southwest of the Reactor Building is the newly constructed Route 3127 which presently serves as the major artery between U.S. Highway 90 in Boutte, La. and Route 3141 in Killona, La. just west of the site. By the early 1980s, Route 3127 has been completed all the way to Donaldsonville, 28 miles west-northwest of the site. There is no current ADT data available for Route 3127. In 1973, it was projected that by 1993 Route 3127 would have an average daily traffic volume of 16,560(5) west of the Route 3160 junction and 18,000(5) east of the junction (see Figure 2.2-2). Traffic volumes on both LA 18 and Route 3127are expected to be substantially increased with the completion of Interstate 310 and the Hale Boggs Bridge crossing the Mississippi River (see Figure 2.1-31). Interstate 310 WSES-FSAR-UNIT-3 2.2-3 Revision 301 (09/07) will connect Interstate 10 and US 61 on the east bank with Route 3127 and U.S. Highway 90 on the west (right descending) bank. The new bridge and I-310 is the only major access to both sides of the river between the Huey P. Long Bridge in New Orleans, 19 miles east-southeast and

the Sunshine Bridge at Donaldsonville, 28 miles west-northwest of the site. The average daily

traffic volume on I-310 (when completed) at the new bridge is projected to be 60,950.

The closest truck monitoring station in the vicinity of the site is located on LA 18 in Taft, La. In 1976 an average of 742 light trucks, 159 heavy trucks (six tires, three axle trucks)

and 53 combination tractor trailer trucks were estimated as having passed this station each

day (5).

Truck accidents in the vicinity of the site are summarized in Table 2.2-2.

b) Rail (EC-5000082218, R301)

The closest railroad to the site is the Union Pacific Railroad which runs across Entergy's property approximately 0.45 miles southwest of the Reactor Building. Other railroads within five miles, are the Illinois Central Gulf approximately 2.20 miles northeast of the site and the Louisiana and Arkansas approximately 3.25 miles northeast of the site (see Figure 2.2-2).

The latter two railroads are across the river from Waterford 3.

In 1977, the Missouri Pacific Railroad (later acquired by the Union Pacific Railroad) had an average of 18 trains a day which pass by the site with approximately 100 cars per train (6). The railroad services all the chemical plants on the west (right descending) bank of the river. Some of the products it ships are dry fertilizers (phosphate based), caustic soda, chlorine, and numerous amounts of industrial chemicals for Union Carbide (7).

In 1977, the Illinois Central Gulf Railroad (later acquired by the Canadian National Railway) operated two trains a day between Baton Rouge and New Orleans. Each train consisted of 85-95 cars. Ninety percent of the cargo was petroleum based products (8).

The Kansas City Southern Railway (formerly the Louisiana and Arkansas Railroad) is the farthest from the site, located approximately 3.25 miles to the northeast from the Reactor Building. In 1977, the railroad had four mainline trains and four work (dodger) trains daily. There was an average of 150 cars on the mainline trains, and 50-75 cars on the dodgers. The cargo on the trains ranged from wheat and lumber to petrochemical products and automobiles (9).

In 1975 there was a total of 65 accidents which occurred in the state of Louisiana on the Louisiana and

Arkansas, the Illinois Central Gulf and the Missouri Pacific Railroads (10). Two of those accidents occurred within approximately five miles of the site. One occurred on the Louisiana and Arkansas railroad in the vicinity of Norco, La. It involved a derailment in which there was $6,450 in equipment

damage, $3,000 in track damage and no injuries (10). The other accident involved a rear end collision between two freight trains on the Missouri Pacific Railroad, which is approximately 0.45 miles to the southwest of the site. One train was pulling 110 cars, the other 72 cars. The total estimated equipment

and track damage was approximately $152,370 (11). There were no injuries and none of the derailed or damaged cars were loaded with hazardous materials (11). (EC-5000082218, R301)

WSES-FSAR-UNIT-3 2.2-4 Revision 301 (09/07)

In 1976 there were a total of 92 railroad accidents which occurred on the Louisiana and Arkansas, the Illinois Central Gulf or the Missouri Pacific in the State of Louisiana. Only one of these occurred within five miles of Waterford 3 in LaPlace, La. It was a derailment involving five cars carrying hazardous

materials, one of which was damaged (10). The accident had an estimated $122,750 worth of equipment damage and $500,000 worth of track damage and no injuries (10).

In 1977, there was a total of 141 accidents which occurred in the state of Louisiana on the Illinois Central

Gulf, Union Pacific, and Louisiana and Arkansas Railroads (10). Of these accidents, three or 2.1 percent occurred within approximately five miles of the site. Two of these occurred at Norco, which is east-northeast of the site and on the east side of the Mississippi River. One of these accidents, on March 10, 1977, involved a derailment of six cars of a train consisting of 12 loaded freight cars, 34 empty cars, and

one caboose. It was due to defective or missing crossties. The damage to track, signal, way and structures amounted to $3,036.00. There were no hazardous materials on the train and no one was

injured.

The second 1977 accident at Norco occurred on September 10th, and resulted in the derailment of five loaded freight cars in a train made up of 27 loaded cars, three empty freight cars and one caboose. This accident was also caused by defective or missing crossties and resulted in damages of $29,800.00 to equipment; $21,000.00 damages to track, signal, way and structures; and $40,000.00 damage to an

unattended car parked on a siding. No hazardous materials were involved in this accident.

The third accident in 1977 occurred at Good Hope which is due east of the site and on the east side of the river. This accident occurred on October 21st and resulted in $3,100.00 worth of damages, made up of $1,500.00 damage to equipment and $1,600.00 damage to track, signal, way and structures. This train

was made up of 123 loaded cars, one empty car, and one caboose. It involved a locomotive collision with a highway user at a grade crossing. There were no injuries and no hazardous materials were involved.

(EC-5000082218, R301)

In 1978, there was a total of 135 train accidents in the State of Louisiana on the Illinois Central Gulf, Missouri Pacific, and Louisiana and Arkansas Railroads (10). Of these accidents, two or 1.5 percent occurred within approximately five miles of the site. (EC-5000082218, R301)

The first of these accidents occurred at Montz which is directly across the Mississippi River from the site and on the east side of the river. This accident involved the collision of a train handling 64 empty freight cars with a highway user at a grade crossing. No hazardous materials were involved in this accident.

There was $25,000 worth of damage to equipment and two persons were injured.

The second 1978 accident occurred at Norco. This involved a train on a siding which consisted of six loaded freight cars, three empty cars, and a caboose. Four of the loaded cars were derailed due to a bolt hole crack or break and this involved equipment damage amounting to $7,280.00. No hazardous

materials were involved in this accident.

(EC-5000082218, R301)

One of the most severe accidents within the vicinity of the site occurred on February 21, 1973 approximately 0.85 miles to the southeast of the site on the Missouri Pacific Railroad. (EC-5000082218, R301)

WSES-FSAR-UNIT-3 2.2-5 Revision 301 (09/07)

(EC-5000082218, R301)

It was a head on collision between a west bound Texas & Pacific (T&P) Work Extra 523 and an east bound Missouri Pacific Extra 1902. Sixteen cars were derailed and three people were killed. The cause

of the collision was the unauthorized intrusion of Work Extra 523 onto the main track from Occidental Chemical Corporation siding. Work Extra 523 had 33 loaded tank cars and three empty cars. Of the 33

loaded tank cars, fifteen contained chlorine for a gross weight (net plus weight of the tank car) of

2,929,040 lbs., seventeen contained caustic soda for a gross weight of 4,316,400 lbs. and one contained

a sulfur chlorine compound with a gross weight of 235,820 lbs.

(12) Work Extra 1902 had three locomotives, 21 loaded cars, 17 empty cars and a caboose. The loaded cars included two tank cars of weight of 225 tons and three cars containing sulphur with gross weight of 600 tons (12). The remaining cars were carrying miscellaneous materials such as bricks, stone, machinery, etc. Of the 16 derailed cars, five were empty, one was carrying caustic soda, one was carrying plastics, four were carrying unspecified chemicals, two were carrying acid, one was carrying fertilizer and two were carrying

sulfur (12). One of the cars which contained sulfur collapsed at its center and some sulfur was spilled. In addition, several other tank cars on both trains were fractured or punctured. The lading of one tank car was adipic acid, a powder which will burn with a violent reaction if thrown into a fire (12). (EC-5000082218, R301)

c) River

The Reactor Building is approximately 1,200 ft. from the Mississippi River channel. A description of the shipping along the river, including types of ships and barges, and occurrence

of shipping accidents is given in Subsection 2.2.2.4.

d) Air

Airports in the vicinity of Waterford 3 are shown in Figure 2.2-4, and their facilities and operations are described in Subsection 2.2.2.5.

2.2.2.2 Description of Products and Materials (EC-5000082218, R301)

A wide variety of products are produced, stored and transported within five miles of Waterford 3. Historical information by company on the products used or produced, the mode of shipment, frequency of shipment, average size of shipment and the maximum amount of hazardous material to be processed, stored or transported is given in Table 2.2-3. Information for this table was obtained by submitting

questionnaires to the industries within five miles of Waterford 3 (13). In some cases the industry's responses were qualified as being proprietary information, and therefore do not appear in Table 2.2-3.

(EC-5000082218, R301)

WSES-FSAR-UNIT-3 2.2-6 Revision 309 (06/16)

(EC-5000082218, R301; EC-39014, R307; LBDCR 15-048, R309)

In 2016, a survey was performed of industrial facilities which store or process toxic chemicals within a 5-mile radius of the Waterford 3 control room. Table 2.

2-3A contains a list of t he facilities surveyed, while Tables 2.2-3B and 2.2-3C contain the data furnished by these facilities. Table 2.2-3B lists the toxic chemicals stored or processed at eac h of these facilities, based on inform ation furnished by the facilities.

Table 2.2-3C contains data on chemicals trans ported to or from each facility by water.

In addition to the products used and manufactured in t he area of Waterford 3, a large number of products are shipped past the site by water, rail, and truck.

The Mississippi River is one of the major freight transportation routes in the Unit ed States. In 1989, 181,802,058 tons (14) of commodities were shipped past river mile 129. Table 2.2-5 lists the amount of hazardous commodities transported between River Mile 129 and 129.9 in 2013. These commodities consist mostly of petroleum products and other

chemicals.

A description of the products transported by rail in the vici nity of the site is given in Subsection 2.2.2.1.2.

Table 2.2-3D lists all hazardous materials which we re transported on the tracks of the Union Pacific Railroad within a 5-mile radius of Waterford 3 in 2014. This list, which was furnished by the railroad (118), includes all cargos classified as hazardous by the U.

S. Department of Transportation. Tables 2.2-3E and 2.2-3F show corresponding data for the Canadian National (118) and Kansas City Southern (118) Railways, respectively.

Commodities are also shipped by truck in the vicinity of the site. The majority of the truck traffic in the area services the chemical and refining companies in the vicinity of the site. Louisiana Route 18 passes within 714 feet of the control room air intake. LA 18 is a local road. Through traffic uses the nearby Route 3127. The two roads run parallel to each other in the immediate vicinity of Waterford 3 and are a little more than one mile apart. Data on shipments of hazardous materials past Waterford 3 in 2015 are listed in Table 2.2-3G. (EC-5000082218, R301; EC-39014, R307; LBDCR 15-048, R309)

2.2.2.3 Pipelines and Gas and Oil Fields

(EC-5000082218, R301; EC-39014, R307; LBDCR 15-048, R309)

There are approximately 49 major pipelines operated by 11 different companies within 2 miles of Waterford 3. Products carried in these pipelines include natural gas, hydrogen, ammonia, LPG, ethane, gasoline, propane, and raw materials. The closest pipelines to the site are Bridgeline Holdings's 16-inch

natural gas line, 0.3 miles to the west, Enterprise Pe lican Pipeline L.P.'s two 20-in ch natural gas lines to Waterford Station and Little Gypsy, approximately 0.4 m iles to the East and to the West. These and other major pipelines carrying hazardous materials within a 2-mile radius of Waterford 3 are shown in Figures 2.2-3A through 2.2-3G. Table 2.2-6 gives a descripti on of these pipelines, including the pipe size, type of product carried, year laid, operating pressure, depth of burial, type of isolation valve, and the distance and direction from the site to the nearest isolation va lve and/or terminus of each pipeline. None of the pipelines listed in Table 2.2-6 are used for gas storage at higher than operating pressure. (EC-5000082218, R301; EC-39014, R307; LBDCR 15-048, R309)

WSES-FSAR-UNIT-3 2.2-7 Revision 301 (09/07)

(EC-5000082218, R301)

(EC-5000082218, R301)

There are four producing gas and oil fields within a five mile radius of Waterford 3 (see Figure 2.2-1).

The closest field to the site is the Norco gas field 1.9 miles northeast of the site. The Norco gas field has one operating well (98,99). The two largest producing fields in the area are the Good Hope oil and gas field, 5.0 miles to the east of the site, and the Bonnet Carre oil and gas field, 4.6 miles to the north of the site. In 1987 the Good Hope oil and gas field had 34 oil wells which produced 3,373,601 barrels of oil, one gas well which produced 2,738,658 mcf (thousand cubic ft.) and one gas condensate well which produced 28,998 mcf (98,99). The Bonnet Carre field in 1987 had 9 oil wells which produced 383,221 barrels of oil, 25,671,781 mcf of gas, and 998 barrels of gas condensate (98,99). The remaining operating gas field in the area is the Lucy gas and oil field 2.2 miles west and west-southwest of the site.

All of these fields are described in Table 2.2-7.

The closest producing well is located 3.3 miles to the west of the site in the Lucy oil and gas field. On

November 11, 1975, this well was producing 316 mcf of gas per day (17).

2.2.2.4 Waterways

The Reactor Building is approximately 1,000 ft. from the shoreline of the Mississippi River, which is one of the major inland waterway shipping routes in the United States. In 1975, 161,751 vessels moving

201,600,768 tons of commodities (see Subsection 2.2.2.2) and carrying 10,462 passengers traveled in

the section of the river between Baton Rouge, La. to, but not including New Orleans, La.

(14). Table 2.2-8 shows the type and drafts of vessels which moved on this section of the river in 1975. The type of ships range from self propelled tankers and dry-cargo ships with drafts of up to 40 ft. to non-self propelled dry cargo vessels and tankers with drafts of 18 ft. or less. The non-self propelled dry cargo vessels and

tankers are the largest number of vessels which move along this route.

Table 2.2-8 is a conservative estimate of the number of ships which passed by Waterford 3 in 1975 for

the reasons given in Subsection 2.2.2.2.

During the period between 1972 and 1976, 62 commercial vessel casualties were reported to the U.S.

Coast Guard to have occurred between River Mile 115 to 135 (18). As defined by 46CFR4.05 a reportable casualty results whenever any of the following occur:

a) Actual physical damage to property in excess of 1,500 dollars

b) Material damage affecting the seaworthiness or efficiency of a vessel

c) Stranding or gounding (with or without damage)

d) Loss of life

e) Injury causing any persons to remain incapacitated for a period in excess of 72 hrs.; except injury to harbor workers not resulting in death and not resulting from vessel casualty or

vessel equipment casualty (18).

WSES-FSAR-UNIT-3 2.2-8 Revision 301 (09/07)

Fifty-three of the 62 accidents reported between 1972-1976 involved some type of freighter, dry cargo barge or liquid tank barge. Eight had commodities specified such as liquid caustic soda, ammonia, styrene, adiponitrile, sulfuric acid, etc, which could be a potential hazard to the Waterford site. The remaining accidents either did not involve any cargo or the cargo was not specified. One accident reported was recorded as being due to an explosion and/or fire involving liquid bulk cargo and was caused by improper safety precautions in either loading inflammable liquid or fueling or repairs (18).

Because of the type of coding the U.S. Coast Guard was using between 1972 and 1975, the location of accidents reported to them: in those years designates the river mile to the nearest 10 miles (e.g., mile 346.6 = 350). It is difficult therefore, to specify the exact location of these accidents in relation to Waterford 3 for the period between 1972 and 1975. In 1976, the U.S. Coast Guard changed its coding so that the location of the accident was given to the nearest river mile. A description of the accidents which were reported in 1976 to have occurred between river mile 124 and 135 is given in Table 2.2-9. This table, however, only shows those accidents which were reported to the U.S. Coast Guard in Fiscal Year (FY) 1976 and is not necessarily a complete list of all the accidents which occurred during that period.

Accidents are listed by the U.S. Coast Guard in the year they were reported to the U.S. Coast Guard not in the year they occurred. The date of occurrence is shown in column one of Table 2.2-9.

In FY 1976, there were seven accidents reported to have occurred on the Mississippi River between river mile 124 and 135. The closest accident to the plant which is located at river mile 129.6 occurred in April 1975 at river mile 128. The accident was a collision with a fixed object (piers, bridge, etc.) caused by restricted maneuvering in congested areas (docks, piers, etc). The accident involved a towboat and a liquid cargo barge carrying an unspecified cargo. Only one accident reported in FY 1976 had a specified cargo which could be considered hazardous to the plant. It occurred in February of 1976 at River Mile

127 AHP (Above the Head of Passes) and involved a liquid tank barge carrying liquids such as ammonia

sulfate liquid fertilizer.

(18) (EC-5000082218, R301)

Within approximately five miles of Waterford 3 there are eight docks and mooring locations (19). All of these are listed in Table 2.2-10 and shown in Figure 2.2-2. The closest to the site is Entergys fuel unloading dock at Waterford SES Units 1 & 2, approximately, 0.5 miles from the Reactor Building.

Others in the area include Occidental Chemical and IMC-Agrico liquid bulk loading and unloading dock, 0.7 miles to the east of the site, Union Carbide's petrochemical and liquid handling facility 1.5 miles to the

east and Shell Oil Company dock facilities 3.6 miles to the east of the site. All others are shown in Figure

2.2.2 and described in Table 2.2-10. (EC-5000082218, R301)

The Circulating Water System intake canal for Waterford 3 (river mile 129.6) extends 100 ft. into the river from the shoreline and has a bottom elevation of -35 ft. MSL. The Mississippi River at this point is approximately 2,850 ft. wide. The deepest channel of the river in this area is at least 100 ft. in depth and

550 ft. in width and approximately 450 ft. from the shoreline (20).

Shipping in the Mississippi River does not follow any specified shipping channel but moves on the river

according to the traffic and depth of the river (21). Ships with drafts of 40 WSES-FSAR-UNIT-3 2.2-9 Revision 301 (09/07)

(EC-5000082218, R301) ft. and less pass by the site (see Table 2.2-8), so that it is possible that a ship or barge with a draft of 40 ft. or less could move in the waters near the intake structure. LP&L has a barge unloading dock just upriver from the intake structure at river mile 129.9 and Occidental Chemical and IMC-Agrico have one

just downriver from the discharge structure at river mile 128.8. There will be some river traffic in the vicinity of these facilities. Pile dolphins have been constructured on either side of these structures as a

warning to any vessels in the area. (EC-5000082218, R301) 2.2.2.5 Airports

Airports in the vicinity of Waterford 3 are shown in Figure 2.2-4. The closest airport to the site is the Triche airstrip located 2.2 miles east of the site. The airstrip is privately owned and there are three single-engine planes based at the airstrip. Two of the planes, Boeing Stearmans (biplane), are used for a crop spraying operation which are during the months of May through October with a peak in July and August.

Most of the spraying is near Plaquemine, La. where many of the takeoffs and landings take place. The other plane, a Cessna 170b (1953 model), is primarily used for pleasure and contributes to most of the movements of Triche airstrip. The owners estimate that there are approximately 40-50 movements per month at the airstrip. The runway is a 2,500 ft. grass strip and is oriented in approximately a north-south direction (20 degrees east of north). During landing procedures the plane is almost always south of the airstrip, east of the site. There have been no accidents at the Triche airstrip since its beginning in August

1973 (22).

Mollere airstrip 7.5 miles to the northwest of the site is another privately owned airstrip at which there are approximately 200 take-offs and landings per year. There is only one single-engine land airplane which uses the 2,500 ft. grass airstrip. The runway is oriented north and south. A left hand approach pattern is used when landing to the south and a right hand pattern when landing to the north. Presently, there are

no future plans for the expansion of facilities at the airstrip (23).

Approximately 11.2 miles to the east-southeast is Seller's Field in Ama, La. It has a 3,300 ft. north-south

grass runway used by a private air club. Presently 20 single-engine planes are based at the field which has approximately 780 operations a year. There are no plans for expansion of facilities at this field (24).

In St. John the Baptist Parish there are plans for the construction of a new FAA approved general aviation airport to accommodate private corporate planes belonging to businesses in the area. The airport is planned to have a 4,000 ft. runway in a north-south direction (170 and 350). In 1982, 44 aircraft consisting of 35 single-engine planes, seven multi-engine planes and two rotorcraft and other types of aircraft, are forecasted to be based at this airport (25,84). By 1997, this total is expected to increase to 103, with 76 single-engine aircraft, 23 multi-engine aircraft and four rotorcraft and other types of aircraft, 23 multi-engine aircraft and four rotocraft and other types of aircraft (25,84). In 1982, the airport is forecasted to have 44,330 operations (25,84,85). A forecast of aircraft operations at the St. John the Baptist Airport from 1982 to 1997 is given in Table 2.2-11.

The closest major airport to Waterford 3 is New Orleans International (Moisant), 11.5 miles east of the

site. In 1976, New Orleans International had a total of 155,903 operations (26). Table 2.2-12 lists aircraft operations at New Orleans International Airport from 1966 to 1976. A forecast by aircraft operations at

New Orleans International Airport from 1980 to WSES-FSAR-UNIT-32.2-102000 is shown in Table 2.2-13. Aircraft using the airport range in size from two seater single engineplanes to large jets such as Boeing 747s.There are three runways at New Orleans International Airport: a 9,227 ft. long runway oriented inapproximately an east-west direction (100 degrees east of north); a north-south runway, 7,000 ft. in length; and a 4,542 ft. long strip in a southwest-northeast orientation(25). It is anticipated that by 1990 a new8,000 ft. runway will be constructed and that the main runway will be extended to 10,500 ft.(25)Other airports in the vicinity of Waterford 3 include Lakefront Airport, Westwego Airport, the U.S. Naval Air Station and Braithwaite (see Figure 2.2-4). None of these airports have approach patterns in the vicinity of the Waterford site. In addition, based on 1000d 2* movements per year, they are far enough away thatoperations at these facilities should not pose a significant hazard to the site.Aviation routes and approach patterns in the vicinity of Waterford 3 are shown on Figure 2.2-4, Figure 2.2-5a and Figure 2.2-5b respectively. The closest low altitude federal airway is approximately five miles to the north of the site(27). Within five miles of the site is the approach path to the main runway at NewOrleans International Airport(28). It is estimated that approximately 35-40 percent of the traffic at the NewOrleans International Airport will fly within five miles of the site. Most of this traffic will be less than 5000 feet above ground level(29). Other low attitude federal airways in the vicinity of the site and the approachpatterns to the north-south runway at New Orleans International are shown in Figures 2.2-4 and 2.2-5.Waterford 3 just barely falls within the boundaries of an air alert area, A-381, as shown in Figure 2.2-6(27).An alert area is an area where there is a high volume of a particular or unusual type of aircraft activity.Alert area A-381 encompasses the Gulf Coast and is designated as such because of the high level of seaplane and helicopter activity in the area going from the mainland to off-shore oil rigs.(2)Aircraft accidents in the vicinity of the site or within five miles of New Orleans International Airport between 1966 and 1976 are listed in Table 2.2-14. The closest accident to the site took place in 1966 in La Place, Louisiana approximately five miles north of the site. It involved a Piper PA-18 in which no one was injured.

An analysis of the probability of an aircraft collision with plant safety related structures and components is provided in Subsection 2.2.3.7.2.2.2.6Projections of Industrial GrowthManufacturing is expected to continue its growth in St. John the Baptist and St. Charles Parishes. Thearea should remain attractive for development of refineries and petrochemicals because of the easy availability of oil resources in the Louisiana coastal areas. Depletion of petroleum resources in Louisiana could have negative effects on these

WSES-FSAR-UNIT-3 2.2-11 Revision 301 (09/07) industries, but the construction of the Louisiana Off-shore Oil Port (LOOP) should offset declining state resources. Additionally, the fresh water and navigational access provided by the Mississippi River is likely to continue to make the area attractive for industrial development (30). Projections by the U.S.

Department of Commerce (31) and projections prepared for the LOOP environmental impact assessment (32) were analyzed to determine future industrial employment trends. This analysis indicates that the coastal Louisiana employment in petrochemical industries is expected to grow rapidly, by four to five percent per year, while employment in refineries is expected to grow by about one percent per year until 1990, after which it should level off. Food products industries, which includes grain elevators and sugar producers are not expected to grow rapidly.

(EC-5000082218, R301)

In general, the most rapid industrial development is projected to take place southeast and northeast of Waterford 3. There are some large vacant industrial sites within three miles of the site and these are

expected to be developed for industrial use during the life of the plant. The properties consist of a 3,100 acre parcel owned by Koch Industries immediately to the west of Killona and the as yet undeveloped portions of the Occidental Chemical and Union Carbide properties. In addition, there are several industries within five miles of the nuclear site which are in the process of expanding or have plans to expand in the near future. By the fourth quarter of 1977, Shell will have invested 210 million dollars creating 160 new jobs and expanding its productive capacity by 480 million pounds of chemicals a

year (4). Union Carbide is investing 425 million dollars to expand its productive capacity by 1.5 billion pounds of chemicals a year and its employment by 50 people by July, 1978. Over the next three years Union Carbide plans to hire 30 more people and to increase its productive capacity by 60 million pounds

of chemicals a year (4). Other industries in the area which have plans to expand in the near future are: IMC-Agrico which plans to double its production of phosphoric acid and increase its employment from

210 to 280 people within the next five years (13) and Good Hope Refineries which is scheduled to expand its existing units, add new units and increase its employment by fifty people (13). Big Three Industries, is planning to begin operation of an air separation plant in December of 1977. The plant which is located approximately four miles to the east-northeast of Waterford 3, will employ 25 people and will produce 325 tons/day of gaseous oxygen and 700 tons/day of gaseous nitrogen. Within two years after the start of the plant, it is expected that there will be a possible threefold increase in plant capacity and an increase in

employment of about 40 people.

2.2.3 EVALUATION OF POTENTIAL ACCIDENTS

(EC-5000082218, R301)

Waterford 3 is situated in an industrialized area. Transportation storage, and use of some of the materials cited in Tables 2.2-3B through 2.2-3G and Table 2.2-5 present a potential for explosions, fires or release of toxic gases. The hazards associated with chemicals transported or stored in quantity in the vicinity of Waterford 3 were evaluated to assure appropriate design consideration. The spectrum of

credible explosive events and missiles generated are addressed in Subsection 2.2.3.1. The main control room design coupled with administrative procedures prevents the incapacitation of main control room operators during postulated toxic gas episodes (see Section 6.4). The delayed ignition of flammable vapor clouds is considered in Subsection 2.2.3.2. (EC-5000082218, R301)

(DRN 03-2055, R14;05-149, R14)

Design Basis Events are potential accidents that have a probability of occurrence equal to or greater than 10-7 per year whose consequences can result in radionuclide releases in excess of 10CFR50.67 guidelines. (DRN 03-2055, R14;05-149, R14)

WSES-FSAR-UNIT-3 2.2-12 Revision 307 (07/13)

(DRN 01-231)

In addition to evaluating the consequences of potential accidents, evaluat ions have been performed postulating the impact of historical events on Waterf ord 3 prior to receipt of its operating license.

Descriptions of these occurrences and their impac t on the habitability of the Control Room are summarized in Appendix 2.2A and are provided for historical information only. (DRN 01-231) 2.2.3.1 Design Ba sis Explosive Events

Review of all combustible materials transported or st ored within five miles of Waterford 3 revealed that several sources presented hazards which merit closer investigation. The sources of hazards are:

a) river transport of gasoline along the shipping channel which passes 1200 ft. north of the safety related structures, and

b) LPG shipments by truck passing the site at a closest distance of 634 ft. from the main control room, and

c) nearby gas pipelines, LPG lines, and/or flammable stationary sources. (DRN 01-464) 2.2.3.1.1 Design Basis Events Arising from Transportation of Explosives and/or Flammables on the Mississippi River (DRN 01-464)

The first case of gasoline transport is analyzed in the light of casualty statistics. Table 2.2-15 cites 146 casualties reported to the Coast Guard during fiscal years 1969-1971 for 140 river miles. Casualties are presented by nature of casualty code categories. Categories 13 through 20 concern all fires and/or explosions which occurred (none of which were cata strophic in nature). Table 2.2-16 illustrates the number of upbound and downbound vessels (58,486 and 58,606 respectively) for a total of 117,092

vessels passing by the site annually.

Using the information under certain broad assumpti on (e.g., uniform spacing and speed of traffic, collisions between all types of vessels equally likely, collisions in all parts of channel equally likely) the probability (P c) that any given ship will have an explosion and/or fire as expressed in categories 13 through 20 of Table 2.2-15, within any one mile is

= 2.2 x 10

-7 incident per ship (EC-40308, R307)

The above frequency of fire and/or explosion incidents does not take into account any factors such as

location of the accident, the actual vessel involved, and the cargo it carries. A closer examination of Table 2.2-15 reveals that location of accidents is a decisive factor influencing accidents. For instance, the stretch of river to the nearest 10 miles of River Mile 90 (AHP) accounts for 32.19 percent of all vessel casualties and 45 percent of all casualties in categories 13-20, River Mile 100 (AHP) and the nearest 10

miles, account for 12.33 percent of all casualties and 18.18 percent of all casualties in categories 13-20, while statistics for the 10 mile stretch centered about River Mile 130 (AHP) show no casualties for fiscal years 1969-1971. Waterford 3 is located at River Mile 129.5 (AHP). Thus the calculation of accident frequency is conservati ve due to favorable WSES-FSAR-UNIT-3 2.2-13 Revision 14 (12/05)River Mile location. Assuming a factor of 100 to account for this favorable location, the frequency of incidents may be reduced to P c = 2.2 x 10

-9 incidents per ship This frequency of occurrence of accidents involving fires and/or explosions is comparable to the probabilities for barge accidents in the moderate to severe categories of Table 3.2-17 in WASH-1239 (33).This number does not take into account the nature of the cargo or vessel. It is conservatively assumed that a frequency of one in 10 ships carries hazardous materials (see Amendment 26 to the Waterford 3 PSAR, Answer to Q2.41-2) the following probability is arrived at:

P e = 2.2 x 10

-10 incidents per ship giving rise to fire and/or explosion in the vicinity of River Mile 130 (AHP), of a vessel carrying hazardous cargo. (DRN 03-2055, R14;05-149, R14) For river traffic, the transport of gasoline poses the most significant hazard for fires and explosions, and although by itself it does not pose a hazard exceeding the 10CFR50.67 guide, it may be taken to be the Design Basis Accident issuing from the transportation of flammable and/or explosive cargo on the

Mississippi River near the site. (DRN 03-2055, R14;05-149, R14) At the time of the PSAR, according to the Louisiana district office of Shell Oil Co. gasoline was shipped by the site in two ways (1) in ships which have a capacity of approximately 300,000 barrels or (2) in barges which hold 10,000 barrels each. These barges travel in groups of two or four. Therefore, the ships are the controlling factor in the remote occurrence of an incident. Gasoline has a density of 6.6

lbm/gallon and there are 42 gallons per barrel. For the case of gasoline tankers, Table 2.2-5 indicates that 1.1 x 10 7 short tons are transported by the site annually. This quantity can be conservatively assumed to be transported by approximately 260 tankers per year with a capacity of 300,000 barrel (bbl). Thus the total probability of incidents that may lead to fires and/or explosions of a ship with a 300,000 bbl capacity is P2.2x10(incidents...)haz. vessels x ships year5.72 x 10 incidents involving fire and/or explosions of a 300,000 bbl gasoline tanker, in the one mile vicinity of River Mile 130 (AHP), per year.

t 10-8 260While tankers with a capacity greater than 300,000 barrels move past the site, the probability of this large tanker exploding is well below 10

-7 per year. The largest tanker according to the survey of industrial and transportation facilities is approximately 750.000 barrels. This tanker passes by the site only once in

1976.According to Robert F. Benedict (34), the upper limit of flammability for gasoline is 7.9 percent. The highest limit of flammability for the gasoline family stated in Publication No. 503, "Limits of Flammability of Gases and Vapors" (35) published by the Bureau of Mines is WSES-FSAR-UNIT-32.2-14 Revision 11-A (02/02) 10.5 percent for cyclopropane. Mr. Benedict has stated that the density of gasoline vapor at the highest limits of flammability is unavailable, but that the combination of 10.5 percent limit of flammability and agasoline vapor density of 0.245 lbm/ft 3 at this limit is conservative. (The 0.245 lbm/ft.3 corresponds to the vapor density of heptane.)The free volume of a 3 x 10 5 bbl ship is 3 x 10 5 bbl x 42 gal/bbl x 0.1337 ft 3/gal = 1.68 x 10 6 ft 3. Using aconservative 10.5 percent gasoline-air mixture (i.e., 0.105 of volume) at a vapor density of 0.245 lbm/ft 3 , the most hazardous cargo in a 300,000 bbl ship is 4.32 x 10 4 lb, or 21.6 tons of gasoline. Assume now a conservative estimate that the 21.6 tons of gasoline vapor yield a detonation identical to one of a TNT charge

of equivalent weight. According to Stull (36), the scaled range isZ distance from plant (ft)/(weight of TNT in lbm) 1200/(4.32 x 1034.21/3 4)/13 From Figure 2.2-7, the peak overpressure for Z = 34.2 is 1.3 psi. The reflected pressure is 2.7 psi which is an acceptable overpressure for the safety related buildings.These values are much more conservative than those obtained through an analysis using Brode's equations, (37,38) which are also conservative.

When dealing with the possibility of a deflagrative explosion, consider the exploding volume of 1.68 x 10 6 ft 3as a spehere of radius 73.75 ft., with energy equipartitioned through the exploding volume. The explosive energy assuming 21.6 tons of TNT is BTU1057.8 kca l BTU 968.3 lb m kcal 500 to n lbm 10 2 ton6.21 E 7 3 exxxxxand the energy densityE E/free volume 8.57 x 10 BTU1.68 x 10 f t51 BTU/ft e 7 63 3In a deflagration type of explosion the maximum energy density imparted to potential missiles cannot

exceedK.E.(BTU) E (BTU/ft) x M(lbm)/p(lbm/ft) 3 m m 3 where M m and l m are the mass and density of the potential missile.

Thus, since the kinetic energy (K.E.) = 1/2 M m V 2, (V = missile speed) the maximum range, (Rmax) of a missile (conservatively neglecting air resistance) is(DRN 01-464)gp EgMp EMgMEK g V R mmm m m21 2 1.).2(2 maxxx(DRN 01-464)

3 f f 2 23)The above equations do not include consideration of air resistance or energy lost in rotation, which woulddecrease the range. Large ships are compartmentalized, so that the assumption of an instantaneous explosion of the entire ship is extremely conservative.The Mississippi River Channel passes approximately 1200 ft. north of the Nuclear Plant Island Structure(NPIS). It is therefore concluded that missiles generated from the explosion of the 300,000 barrel ship cannot reach the NPIS with a large, destructive missile.According to the U.S. Department of Commerce detonations cannot occur in gasoline tankers. In adetonation, the pressure pulse travels at sonic velocity (supersonic in the pre-shock medium) and the enthalphy change across the shock wave actually causes the combustion and blast propagation. To have a detonation the blast must be caused by an extremely high energy source and by suitable geometric configuration. The energy source necessary to achieve a deflagrative explosion is such that a shock wave is not formed and the flame propagates at a flame velocity which is much lower than sonic velocity.Thus deflagrative explosion of a 300,000 barrel tanker whose cargo is a critical mixture of gasoline and airis a design basis for the safety related structures.2.2.3.1.2Design Basis Event Arising from the Transport of Explosivesand/or Flammables by TruckA review of truck traffic reveals that the governing explosive and/or flammable event would arise from aremote and unlikely accident to an LPG tank truck on route 18 at a critical distance of 462 feet north, east or west of the Nuclear Plant Island Structure.At this distance, it is assumed that 10 percent of the fuel is vaporized to form an explosive mixture ofpropane and air. Thus a truck carrying 10,500 gallons of LPG, at a density of 36.21 lbm/ft 3, would yield0.1 x 10,500 gal x 0.1337 ft gal 3 x 36.2 lbm ft 3 = 5083 lbm of detonable propane vapor.If a conservative estimate of 240 percent TNT equivalent is used, the scaled range isZ 462(12200) 1/3yielding a peak overpressure 3.0 psi and a peak reflected overpressure of 6.5 psi.

WSES-FSAR-UNIT-32.2-16For an explosion to occur in the tank, the tank would have to contain just propane gas in a detonablemixture with air; i.e., five percent propane gas by volume. For a 10,500 gallon tank truck and propane gas density of 0.1154 lb/ft.

3, there would be:0.05 x 10,500 gal x 0.1337 ft gal x 0.1154 lb/ft 8.10 lbm of gas 3 3At 100 percent TNT equivalent we would haveBTU1084.3opanePr16TNT416.2 x kcal BTU984.3 lb kcal500lb1.8E 4x=xx=the energy density isE 3.84 x 10 BTU / 10,500 gal x 0.1337 ft gal 27.58 BTU/ft 4 3 3Thus, the maximum range (Rmax) of steel fragments isft75.87)ft/lbm(489)sec/ft(2.32seclb)lbmft(2.32 BTU)ftlb778(ft)BTU(58.272 R 3 2 2 f f 3 max=xxxx=Thus there is no hazard from an LPG truck deflagrative explosion due to missiles.In response to the NRC Staffs concern regarding the possibility of the formation of a fuel air mixture clouddue to a fuel tank-truck explosion on Highway 18 and its subsequent detonation over the plant, probabilities of accidents leading to different consequences were examined as follows:The probability that an LP gas truck accident would take place within the stretch of road passing in theimmediate vicinity of the plant was assessed from historical data, as reported in WASH 1238 (see Table 2.2-17) and is equal to 1.3 x 10

-6 accidents per vehicle mile.The probability per vehicle mile that an accident will occur that will have consequences ranging from minor to extreme varies substantially with the more severe accidents being considerably less probable.Conservatively, it was assumed that the probability of a tank truck accident of the minor categoryrepresented a base estimate of the frequency of truck accidents in the Waterford 3 vicinity. The frequency with which these accidents would be accompanied by a spill or leak is 0.02 times less, this being the fraction of accidents involving tank trucks with WSES-FSAR-UNIT-32.2-17sufficient impact to cause rupture of the tank. As stated above, the probability of ignition and explosionfrom a spill is determined by DOTs Office of Hazardous Material to be 0.0113. The overall probability of an in-transit explosion of a LP gas truck is thus 2.94 x 10-10 explosions per vehicle mile. There arehowever different kinds of explosions/detonations with different consequences. Leaking vapor can ignite and explode immediately or can form low lying vapor air clouds which can explode after a delay.Tank truck data (from Risk Analysis in Hazardous Materials Transportation, Volume 1, University ofSouthern California, PB-230810, March 1973) is rather inconclusive, but shows that out of forty-four (44) accidents, seventeen (17) occurred en-route. Of the en-route accidents, only one resulted in a large explosion which was at the accident scene. The other explosions occurring during unloading, or as a result of leaks were also localized at the accident scene. In lieu of adequate tank truck data, the corresponding rail data from the same reference has also been examined. This data does present evidence of one true delayed air-vapor detonation of out of seventy-seven (77) accidents reviewed.When all of the tank-truck and rail accidents leading to leaks and fire with explosions are counted, onlyone out of sixty (55 rail and 5 tank-truck) is assessed to be a true air-vapor explosion/detonation resulting from significant quantities of vapor being released at the accident location. It is concluded therefore that for significant leaks of vapor the probability of a delayed air-vapor cloud detonation/explosion is between one to two orders of magnitude less than the probability of an immediate in situ explosion.The data however is insufficient to determine whether such conclusion is also applicable to relatively smallleaks of vapor. For such small leaks flammable air vapor clouds would be formed not far from the leak location even under light winds. Hence, it is not possible to determine from the data whether an explosion had really occurred at the leak location or its vicinity.On the basis that 3,650 LP gas trucks pass the vicinity of the Waterford site per year, the yearly probabilitythat an accident would occur within the mile of road closest to the plant, which would cause a fire or ex-plosion at the accident location is determined to be 1.07 x 10

-6.The probability that such an accident can lead to the delayed explosion/ detonation of a large air-vapor cloud is about 1.82 x 10

-8. This number is derived from multiplying 1.07 x 10

-6 per year per mile by theprobability that an explosion will be a delayed detonation/explosion of a large air vapor cloud which is determined to be about 0.017 from the previous arguments.Another way to examine what the probability of a delayed detonation/deflagration of an air-vapor cloud isin the plant vicinity, is to recall that only accidents of some severity can lead to leaks capable of forming clouds of considerable size.The probability per vehicle mile of severe accidents is lower than that for minor severity, and is reported inTable 2.2-17 to be 8 x 10

-9. Applying the same ratios for frequencies of leaks and spills and explosions,and multiplying by the truck traffic one arrives at a probability per mile per year of an accident leading with potential for delayed detonation of a significant cloud of 6.6 x 10

-9, a number which is comparable withthat previously derived.

WSES-FSAR-UNIT-32.2-18This probability is warranted to be too low to consider such event as part of design. However, theprobabilities of a deflagration/detonation at the site of the accident; of a fire in the immediate vicinity of the accident, and of a relatively small leak leading to vapor clouds which can suffer delayed ignition and detonation are larger, and thus the plants ability to withstand such hazards has been analyzed. Analysis of the in situ detonation and deflagrations in the vicinity of the accident are stated above. Thermal hazards from fires in the vicinity of the accident are addressed in Subsection 2.2.3.2.The vapor clouds that can be formed by leaks of approximately 10 lb/sec or smaller, have beendetermined on the basis of atmospheric dispersion under 2.6 fps wind and Pasquill F meteorology, as well as gravity slumping, and their detonations have been found to present no hazards to the plant.2.2.3.1.3Nearby Gas Pipelines 2.2.3.1.3.1Natural Gas Pipelines A review of the pipelines carrying flammable and potentially explosive materials, within a five mile radius ofWaterford 3 reveals that the most hazardous line is most likely to be Bridgelines 26 inch natural gas line which is approximately 0.6 miles (3,168 ft.) from the plant. This line is taken as the line for the design basis accident analysis due to the proximity of the line and the potentially high transport rate of gas.The natural gas transported is assumed to be methane.

The consequences of a complete severance of the 26 in. natural gas line are evaluated on the basis of thefollowing assumptions:a)Double ended rupture of the 26 in. pipe.

b)Gas escapes from both ends of the ruptured line.

c)Stagnation pressure upstream of break in both ends is the maximum operating pressureof the line ie, 550 psig.d)The discharge from the break is divided into an initial transient when the flow fromboth broken ends may be choked, and steady flow (due to continued pump operation).The gas line operates at a maximum flow rate of 6.5 x 10 6 ft 3/hr, (at standard temperature and pressure)or 1.56 x 10 8 ft 3/day. The density of methane ( CH 4) is 0.037 lbm/ft 3 (at standard temperature andpressure).

Therefore, the flow rate in the unruptured line is:5.77 x 10 lbm/day lbm/ft 3.6 x 10 ft/day 42 ft/sec 6 3633 16.where 1.6 lbm/ft 3 is the approximate density of methane in the line at 550 psig and 105

°F.

WSES-FSAR-UNIT-3 2.2-19 Revision 15 (03/07)

To determine whether choked flow exists, the natural gas is assumed to behave as an ideal gas, even though this assumption can lead to errors of as much as 50 percent in the estimation of densities (in the

conservative direction).

For an ideal gas, the critical pressure, at which the mass flow rate in the break area cannot be increased

regardless how low the back pressure is made is given by: (DRN 06-905, R15) 1 1 2k k o kP*P (DRN 06-905, R15) where:

Similarly the critical density is given by

(DRN 06-905, R15) 1 1 1 2k o k* (DRN 06-905, R15)

Thus for the stagnation pressure of 565 psia, choked flow will exist as soon as the exit pressure is dropped below 308 psia. Thus choked flow will exist at the break. The shock wave which is created at the exit plane at the instant of the break will travel back through the line (both ends) at sonic speed until the whole line to the pump stations has been decompressed. At this time the flow can be assumed to

unchoke.

To calculate the maximum flow rate out of the break, the equation of continuity at the critical (choking)

plane can be used, thus

Thus, W =* V* A* = 1.51 x 1110 x 3.69 = 6185 lbm/sec The initial transient flow will behave as a high momentum jet with rapidly decaying exit plane pressure which will not have sufficient time to form a hazardous detonable cloud. A small detonable cloud, however, may be

present for a short duration on the order of minutes, but will not present a problem to the plant.

The steady flow condition is the one requiring closer investigation due to the (possible) long duration of release of methane at the pumping rate of 6.5 x 10 6 ft 3/hr or 67 lbm/sec. The duration of steady flow release is governed by the pipe inventory for length of pipe between pumping stations.(DRN 01-464)

The dimension of the detonable plume downwind of the break are evaluated for a Category F stability, and a constant, invariant wind speed of 2.6 ft/sec. The centerline (directly downwind) concentration cl of the methane (excluding buoyancy) is determined by:(DRN 01-464)

Table 2.2-18 gives the dimension of the methane cloud downwind of the break neglecting buoyancy. The flow out of the break is 67 lbm/sec.The potential cloud configuration (neglecting buoyancy) which can detonate is the fraction of the cloud which

falls within the flammable limits (4.8 and 14.0 percent).

The maximum distance from the plume axis to the lower limit will occur at the point where centerline concentration is that of the high flammability limit (14.0 percent). This is given by y = 82 ft and z = 41 ft.

WSES-FSAR-UNIT-32.2-21 Revision 11-A (02/02)Thus the dimensions of the semiellipsoid (bounded by the ground) of the low concentration limit for flammability yields a cloud of the volume (V

1) equal to:

V low = (2/3) x 1582.5 x 82.2 x 41.1 = 1.12 x 10 7 ft 3 Similarly, the dimensions and volume (V high) of the cloud at the high flammability limits are given by:

V high (2/3) x 816 x 48.12 x 24.06 = 1.98 x 10 6 ft 3 This yields the volume of the methane cloud within the flammable limits (V net) as: V net = 1.12 x 10 7 - 1.98 x 10 6 = 9.22 x 10 6 ft 3 A realistic analysis leads to a consideration of buoyancy effects since methane is considerably lighter than

air.(DRN 01-464)

As a result of buoyancy, escaping methane will rise with a vertical speed greater than the assumed wind speed. The vertical speed leads to additional significant dispersion of the cloud which reduces the

horizontal downwind, horizontal cross wind and vertical dimensions of the cloud to 0.465 of the original

dimensions (56).(DRN 01-464)

A comparison of the distances of the LPG tank truck (see Subsection 2.2.3.2) and the methane cloud from the plant indicates that a fireball resulting fr om an LPG tank truck break is the dominant hazard and constitutes the design basis accident for this type of externally generated fire.

(EC-5000082218, R301) 2.2.3.1.3.1.1 Hazard Assessment of 16-inch Bridgeline Natural Gas Line (EC-5000082218, R301)

The 1988 survey of pipelines within a 2-mile radius of Waterford 3 revealed only two new lines built since

the previous survey in 1979. Both lines carry natur al gas to the LP&L Waterford G.P. 1 & 2. One pipeline, the Waterford Lateral oper ated by the Bridgeline Gas Distribut ion Co., with a nominal pipe size of 16 inches, is fed by the 26-inch Bridgeline (forme rly Texaco) main line. The other, operated by LP&L, has a nominal size of 14 inches and brings gas from the Acadian (formerly Sugar Bowl) 20-inch line. Since the 16-inch line is nearer to Waterford 3 and has a greater capacity, the results of a hazard

assessment of this line envelope the 14-inch line.

A simple scoping analysis was performed to assess the effect of a pipe break of the new line on Waterford 3, employing the methodology used in Subsection

2.2.3.1.3.1 for evaluating the effect of a break in the Bridgeline 26-inch pipeline.

(EC-39014, R307)

The break was postulated to occur at the nearest isolat ion valve on the new line, which is 2,600 feet from the safety-related structures of Wa terford 3. Although a portion of the pipeline passes slightly closer to the plant, as shown in Figure 2.2-3c, the pipe at this point is buried at a depth of three feet. A break in the buried pipe is highly unlikely. If such a break were to be postulated nevertheless, the resulting flow of gas to the surface would be considerably attenuated by the earthen cover. Therefore, the break at the isolation valve constitutes the maximum credible accident. (EC-39014, R307)

(EC-5000082218, R301)

The final product of the previous analysis is the ca lculation of the peak overpressure which would be experienced by safety-related structur es at Waterford 3. If the 16-inch line were assumed to have the same pumping rate as the 26-inch line, 6.5 x 10 6 scf/hr, the mass and the dimension of the detonable cloud would be the same as calculated in Subsecti on 2.2.3.1.3.1. This assumed rate is very conservative, inasmuch as the 26-inch pipeline feeds the 16-inch line. (EC-5000082218, R301)

Figure 2.2-7 presents a curve which relates the overpr essure to the scaling parameter, Z. This parameter is calculated by the following equation, whic h is adapted from the one shown on page 2.2-23.

WSES-FSAR-UNIT-32.2-24Z R - r M Z scaling parameter for determining overpressure 32.5 R distance of pipe break to safety-related structure 2,600 feet r maximum distance of detonation from pipe break under assumed meteorological conditions 1,104 feet M equivalent mass of TNT 9.76 x 10 lbs1/2 4To increase the accuracy of interpolating the curve in Figure 2.2-7 to determine the overpressure, it isnoted that the portion of the curve between lines representing 10 psi and 1 psi is nearly linear. The linear equation representing this portion of the curve can be written aslog p = log 300 - 1.5 log Z p = overpressure = 1.6 psiusing the value of Z calculated above. This overpressure can be compared to that from one of the design basis explosive events discussed in Subsection 2.2.3.1.1, namely the explosion of a gasoline tanker on the Mississippi River. For that event, Z = 34.2 the value of which is not much different from the value obtained above. To compare the results of the new calculation with the tanker explosion, the overpressure for Z = 34.2 was re-calculated, using the above equation, and an overpressure of 1.5 psi was obtained. (The difference between this value and the 1.3 psi given in the previous section can be attri-buted to individual judgement in reading the graph in Figure 2.2-7.) Thus, the calculated overpressure from a rupture of the new pipeline is not significantly higher than that from the tanker explosion. It is considerably less than the 3.0 psi which was calculated in Subsection 2.2.3.1.2 for the postulated explosion of an LPG truck on Louisiana highway 18.In summary, the pumping speed inside the new pipe would in reality be less than that assumed in thisanalysis, resulting in a detonable cloud both smaller in spatial dimension (therefore remaining at a greater distance from safety-related structures) and lower in explosive power. It is thus concluded that the potential hazard posed by the new pipeline is bounded by previously analyzed explosive events.2.2.3.1.3.1.2Hazard Assessment of Evangeline Natural Gas Pipeline Project In April 1992, construction started on the Evangeline Pipeline. This pipeline supplies natural gas to theWaterford 1 and 2 and Little Gypsy Stations of LP&L. A 24 inch pipeline enters the LP&L property to the south-east of Waterford 3. The 24 inch pipeline connects to WSES-FSAR-UNIT-32.2-25 Revision 12 (10/02) two 20 inch pipelines at a pig trap station just south of the Texas and Pacific Railroad tracks. One 20 inchpipeline then runs parallel to and slightly west of the existing 26 inch Bridgeline pipeline to supply Little

Gypsy. The other 20 inch pipeline runs parallel to the existing 16 inch LP&L pipeline to supply Waterford 1

and 2. The maximum natural gas flow rate in the 24 inch pipeline is 2.50 x 10 8 scf/day. With the exception of the pig trap station, the Evangeline Pipeline is buried for its entire length. Reference 100 provides a

detailed description of the Evangeline Pipeline.

To assess the effect of the new pipeline on Waterford 3, pipe breaks are assumed to occur at the pig trap station and at the Waterford 1 and 2 header. These are the only two locations where the pipeline is above

ground. A break in the buried pipe is highly unlikely. If such a break were to be postulated nevertheless, the resulting flow of gas to the surface would be considerably attenuated by the earthen cover. Therefore, the breaks at the pig trap station and at the Waterford 1 and 2 header constitute the maximum credible

accident.The effect of the pipe breaks is analyzed using the methodology used in Subsection 2.2.3.1.3.1 for evaluating the effect of a break in the Bridgeline 26 inch pipeline. The pig trap station is a minimum of 4000 feet from the safety-related structures of Waterford 3. The maximum natural gas pumping rate at the pig

trap station is 2.50 x 10 8 scf/day or 2.89 x 10 3 scf/sec. Table 2.2-23 gives the dimensions of the methane cloud downwind of the break neglecting buoyancy. The overpressure at the Waterford 3 safety-related

structures from a pipe break and subsequent explosion at the pig trap station is determined to be 0.96 psi.For the analysis of the break in the pipeline at the Waterford 1 and 2 header, the overpressure results

presented in Subsection 2.2.3.1.3.1.1 are bounding.

The Waterford 1 and 2 header is 2600 ft. from the Waterford 3 safety-related structures. The maximum flow rate in this section of the Evangeline Pipeline is 6.25 x 10 6 scf/hr. This is slightly less (96%) than the flow rate of 6.5 x 10 6 scf/hr that was used in the analysis of Subsection 2.2.3.1.3.1.1. If the new pipeline was assumed to have the flow rate of 6.5 x 10 6 scf/hr, the overpressure of 1.6 psi that was calculated in Subsection 2.2.3.1.3.1.1 would apply. In reality, the actual overpressure resulting from a break and

explosion at the Waterford 1 and 2 header would be slightly less than 1.6 psi.In summary, the explosion overpressures at the Waterford 3 safety-related structures due to breaks in the

new Evangeline Pipeline, at the pig trap station and at the Waterford 1 and 2 header, are less than the 3.0

psi which was calculated in Subsection 2.2.3.1.2 for the postulated explosion of an LPG truck on Louisiana

Highway 18. It is thus concluded that the potential hazard posed by the Evangeline Pipeline is bounded by

previously analyzed explosive events.(DRN 02-865)2.2.3.1.3.1.3Hazard Assessment of Oxy-Taft Cogen Lateral Natural Gas Pipeline Project In June 2002, construction started on the Oxy-Taft Cogen Lateral Pipeline. This pipeline supplies naturalgas to the Occidental Chemical Corporation Cogeneration Units that are sited to the East of Waterford 3.The new pipeline is a relatively short pipeline that connects the new cogeneration units to an existing natural gas pipeline. The new 12.75 inch diameter pipeline enters the LP&L property to the south-east of Waterford 3 and runs along the east side of the LP&L property to connect to the cogeneration units. The maximum

natural gas flow rate in the 12.75 inch diameter pipeline is 160 x 10 6 scf/day. With the exception of the section of pipeline at Bridgeline's existing surface site, the Oxy-Taft Cogen Lateral Pipeline is buried for its entire length to a depth of between six and twenty feet. Reference 107 provides a detailed description of the

Oxy-Taft Cogen Lateral Pipeline.

To assess the effect of the new pipeline on Waterford 3, a pipe break is assumed to occur at the above

surface section of the pipeline. A break in the buried pipe is highly unlikely. If such a break were to be WSES-FSAR-UNIT-3 2.2-26 Revision 307 (07/13)

(DRN 02-865, R12) postulated nevertheless, the resulting flow of gas to the surface would be considerably attenuated by the earthen cover. Therefore, the break at the above ground section of t he pipeline constitutes the maximum credible accident.

The effect of the pipe break is analyzed by compari ng the break in the Oxy-Taft Cogen Lateral pipeline to the break in the Evangeline 24 inch pipeline, at the pig trap station, that is discussed in Subsection 2.2.3.1.3.1.2. The Evangeline pipeli ne pig trap station is a minimum of 4000 feet from the safety-related structures of Waterford 3 while the above ground se ction of the Oxy-Taft Cogen Lateral pipeline is a minimum of 4400 feet from the safety related struct ures. The maximum natural gas pumping rate for the Evangeline pipeline at the pig trap station is 250 x 10 6 scf/day while the maximum natural gas pumping rate for the Oxy-Taft Cogen Lateral pipeline is 160 x 10 6 scf/day. Since the postulated break in the Oxy-Taft Cogen Lateral pipeline is farther away from t he Waterford 3 safety related structures and has a smaller gas flow than the Evangeline pipeline the over pressure from a postulated explosion will be less than the overpressure from the Evange line pipeline explosion, i.e. less than 0.96 psi. This is less than the limiting overpressure of 3.0 psi, which was calculated in Subs ection 2.2.3.1.2 for the postulated explosion of an LPG truck on Louisiana Highway 18.

It is thus concluded that the potential hazard posed by the Oxy-Taft Cogen Lateral Pipeline is bounded by previously analyz ed explosive events. (DRN 02-865, R12) 2.2.3.1.3.2 LPG Pipelines (EC-39014, R307)

The pipelines passing within 3000 meters of the plant safety related structures are shown on Figure 2.2-3c. Also shown in this figure is the location of isolation (or check) valves on the pipelines. Table 2.2-19 lists the expected releases that woul d occur for a break in the pipelines. (EC-39014, R307)

Analyses conducted of the potential effects on plant safety-related st ructures from escaping air-vapor clouds indicate that a break in the Texaco 6 in. LPG li ne closest to the plant or a break in the 8 in. Union Carbide LPG line would present about equal hazards.

This conclusion is based on the following analyses wh ich are predicted on the following assumptions for the LPG (propane) lines.

The peak flow rate at t=0 results to be 87,000 lbm/ft 2 sec of liquid at a specific volume of 0.031 ft 3/lbm escaping with sonic velocity, i.e., 2570 ft/sec. This disc harge will last a fraction of a second; i.e., the time for the wave to travel back to a location where frictional pressure drop equals the pressure drop to saturation. Thereafter steady blowdown will proceed at the conservative rate of the two phase critical

mass flow until inertial flow is established.

To estimate the flow rate out of the break, Fauske's equation (58) for critical two phase mass velocity is used:

G crit = (- g c/(k 1 dv g/dp+k 2 dx/dp+k 3 d v f/dp))1/2 where:

g c = 32.2 lbm ft./lb f sec 2 (DRN 01-464, R11-A) k 1 = (1 - x + x)x k 2 = v g (1 + 2x - 2x) + v f (2x 2x + 2) k 3 = (1 - x( - 2) - x 2 ( - 1)) (DRN 01-464, R11-A) and = (v g/v f)1/2 WSES-FSAR-UNIT-32.2-27 Revision 12 (10/02)

Solution of Fauske's equation yields:

G crit = 1433 lb/ft 2 sec Hence for the given pipe area (0.196 ft

2) corresponding to a 6 in. line the flow rate out of the break is at most566lbm/sec, assuming that it gushes out of both ends of the broken pipeline.

At a subsequent time as the pressure in the line falls, the flow becomes inertial or alternatively inertial or two phase critical.

The portion of the piping not pump pressurized will drop rapidly to saturation pressure. The saturated liquid inertial flow, which is higher than the two phase critical flow for the same pressure, is approximately 30 lb/sec. Hence one can conservatively assume that a maximum of 30 lb/sec issue continuously from the unpressurized side of the break after the initial period of time required to depressurize the line to near

saturation pressure. This time for a line length several miles long is just tens of seconds.

The pump pressurized side behaves equally for the 6 in. line, but differently for the 8 in. Union Carbide line since the pump at peak flow can deliver approximately 70 lb/sec. Hence from the pump side of the break acontinuous flow of approximately 70 lb/sec can be expected for the 8 in. line and 30 lb/sec for the 6 in. line.The total long term escape flow from the break can thus be taken as approximately 100 lb/sec. for the 8 in.

Union Carbide break or 60 lb/sec for the 6 in. line. If the break on the latter occurs nearest the planthowever, the automatic isolation valve would stop flow from the pressurized end, hence only 30 lb/sec would escape.Since about 1/3 of this vaporizes, then the vapor flow corresponds to a uniform source of propane vapor of 36 lbm/sec or 9.0 ft 3lb x (36 lbm/ sec) = 324 standard cubic feet per second which is available immediately for atmosphere dispersion in the 8 in. line case or 1/3 of that for the 6 in. line breaking at the worst location.This vapor flow rate is of the same order of magnitude as that observed by Burgess and Zabetakis (59) in their investigation of a propane line break in Port Hudson, Missouri, and this lends credence to the simple model employed to compute the flow rate out of the break.

Another check on the validity of the model is obtained by comparison of predicted and observed total quantities of propane escaped from actual breaks. For instance, for the Port Hudson, Missouri break, the total release of liquid propane estimated by Burgess and Zabetakis during the first 24 minutes is 750

barrels.For 100 lbm/sec and the specific volume of saturated liquid propane the barrels released the first 24 minutesare estimated at 100 lbm/sec (0.031 ft 3/lb) (1 barrel/5.61 ft

3) 24 min. (60 sec/min) = 795 barrels. This goodagreement confirms that the contribution from the subcooledblowdown and critical two phase blowdown portion is negligible.a)Assumption in calculation:1)Double ended rupture or slot rupture with slot size equal to twice the flow area of the pipeline. Rupture occurs instan taneously at closest location to the plant.2)The released LP liquid gas mixture initially escapes from the break at the critical velocity for single phase flow at the design pressure of the line, then drops to two phase critical flow at its saturation pressure and finally to inertial flow from one end and the

flow passed by the pumps at the other end, when the pressure in the pipeline falls.

WSES-FSAR-UNIT-32.2-28 Revision 12 (10/02)3)The temperature of the atmosphere is assumed to be 72

°F. Higher temperatures would lead to higher vaporization of escaping LP fluid, but the initial flow rate would be less due to the higher quality at the exit plane.4)Propane disperses toward the plant at 0.8 m/sec Pasquill F stability condition as an airborne cloud, or alternatively, it drifts by gravity toward the plant.5)Regard less of the potential sources of ignition, a detonation of the resulting cloud is assumed to occur at selected centroids of the cloud, after the centerline concentration has reached the rich limit.b)Calculation of Flow Rate Out of the BreakThe propane in the line will, upon the instant of the break, decompress isentalphically to a saturation pressure of 125 psia essentially immediately because of the very

large speed of sound in the liquid. A decompression wave will travel very rapidly away from the

break leaving the fluid behind it at the saturation pressure. Since the propane would issue from the

break at 72

°F, approximately 1/3 of it would quickly vaporize, cooling the remainder to its boiling point of about -44

°F. Hence the process of decompression is described by the throttling process in a pressure vs. enthalpy diagram. From such a diagram the exit plane quality, x, of the fluid can be

estimated from:

v = v f + x v fg where:(DRN 01-464) v = 2.4 ft 3/lb, v f= 0.0275 ft 3/lb, v fg= 6.6 ft 3/lb, fg f vvv x(DRN 01-464)

Hence: x = 0.36During the initial phase of the blowdown of the pipe (single phase flow) the maximum flow rate can be estimated from:G-g(J/J')(p/v)

Max c s oSince the constant entropy and constant enthalpy lines essentially coincide from the

initial condition to the saturated state of P = 125 psi, v f = 0.0319 ft 3 /lbm, the partial derivative can be evaluated as the ratio of the differences P v1.06 swhere the initial v is taken along the isentrope at the initial pressure, v0.0311 i.The same methodology applied to the events at Ruff Creek (60) and Austin (61) produced the following comparison.

WSES-FSAR-UNIT-32.2-29 Revision 12 (10/02)

At Ruff Creek a 0.0174 ft 2 break is computed to have a mass flow rate of 20.5 lb/sec during the firstphase of the accident, lasting approximately 1-1/2 hour, and then a 5.5 lb/sec release rate for the remaining 14-1/2 hour. The predicted escape quantity of propane is 1,691 barrels, while

approximately 1,800 barrels were observed to have escaped. In Austin, a 0.163 ft 2 break is computed to release an average of 117 lb/sec during the 1.17 hr required to isolate the broken section. The contents of the isolated section escape thereafter. In this case 6,307 barrels are

predicted to have escaped versus the observed 5,540.

Two scenarios can be imagined for the ensuing clouds of propane-air mixtures forming after the break. The first one envisions a cloud formed by the propane being transported by atmospheric

dispersion toward the plant site. The second one assumes that the propane forms a very tenacious layer close to the ground, wherein air entrainment only occurs at the air surface of the layer. This

fog-like ground-hugging cloud advances toward the plant under its own gravity (cloud slumping) and

because of sloping ground. It is to be noted that the ground actually slopes away from the plant.c)Calculation of Detonable Cloud Size - Atmospheric - Dispersion The dimension of the detonable plume downwind of a 325 ft 3/sec propane source, for Category F stability and a constant invariant wind speed of 2.6 ft/sec are given in Table 2.2-20.

The centerline (directly downwind) concentration of propane is determined by:

X Q cl yz u where: Q = 325 ft 3 (STP) of propane per second u = 2.6 ft/sec (0.8 m/sec) andy ,z are the plume dispersion standard deviations obtained from Ref. 71, which are shown on Figure 2.2-14.

The off-centerline concentrations are determined by:

[]{}X X exp -1/2(y/+ (z/)

cl y z 2)2 It is very important to determine which are the proper dispersion standard deviations to be used in solving for the equilibrium 1 concentrations.

Dispersion standard deviations for instantaneous "puff" releases and continuous

constant releases are considerably different; the former being much smaller than the latter.The reason for this is that the continuous release deviations account for a part of averaging process caused by wind vagaries resulting in meandering of the plume about its axis.

They and z then account for this effect. For a puff release this meandering averaging process is absent and the puff disperses more slowly. The case of a pipeline break is neither a puff release

nor a continuous constant release, but rather a continuous release at an initially rapidly decreasing

rate, followed by an almost constant release.

WSES-FSAR-UNIT-32.2-30The meandering process would then be in effect and the proper dispersion standarddeviations are the continuous release standard deviations.The potential cloud configuration for a 6 in. LPG line is plotted in Figure 2.2-8.

The shaded portion represent the fraction of the cloud which falls within thedetonable limits. These limits are reported in Reference 15 to be 7.0 percent and 2.8 percent, respectively. Also shown is the flammable cloud. The flammable limits are 9.0 percent and 2.2 percent, respectively.The volume of the detonable cloud is calculated to be that of the difference betweenthe ellipsoid enclosing all gas above the 2.8 percent mixture and the ellipsoid engulfing the gas above the 7.0 percent mixture level.Volume of ellipsoid (2.8%) = 1.78 x 10 6 ft 3Volume of ellipsoid (7%) = 4.2 x 10 5 ft 3Volume of detonable cloud = 1.35 x 10 6 ft 3d)Calculation of Effects From DetonationFrom an enthalpy of detonation release of 260 K cal/lb of propane air mixtures of 4.9 percent (enthalpy of detonation is insensitive to mixture ratios between four and five percent),

and a volume of 900,000 cubic feet, it is possible to compute the total energy released in a hypothetical detonation of the entire detonable cloud, assuming that the whole cloud is at a mixture averaging 4.9 percent.The total volume of propane in the detonable cloud is 4.42 x 10 4 ft 3 and the volume ofair = 8.6 x 10 5 ft 3. The total weight of the mixture is approximately:1.36 x 10 ft[(13.3) (0.951) + (0.049)(9.43)] ft/lb 1.037 x 10 lb Total enthalpy released 2.69 x 10 K cal Equivalent TNT 2.69 x 10500 K cal K cal lb TNT 26.97 tons of TNT 63 3 5 7 7Comparison of this figure with the occurrence at Port Hudson, Missouri(59) shows thatthis estimate might really be the minimum hazard expected from the break, and that ground andatmospheric conditions may result in more propane being trapped in a detonable cloud.The absolute upper limit of the detonable cloud would be a cloud where all the liquidpropane which escapes from the break eventually vaporizes and mixes with air and the other over rich vapor in a detonable mixture.

WSES-FSAR-UNIT-32.2-31Assuming that the heat to vaporize the liquid propane comes from the air then itwould require approximately 4.15 lb of air at 72

°F to vaporize one lb of propane at-44

°F.The resulting cold mixture would be 19.4 w/o or 11.4 percent by volume of propane,and it would be denser than the ambient air. Thus it is possible to visualize a ground layer of composition above the detonable limit, which when warming up will contribute appreciably more propane to the detonable cloud, than that calculated by the dispersion technique. This ground layer can eventually become dispersed in the atmosphere as it warms up or it can move under gravity effects. For lower atmospheric temperatures proportionately more air would be required tovaporize the propane. At near freezing temperatures (~32

°F) vaporization would result inmixtures of seven percent by volume of propane, thus at the detonable limit.Portions of the liquid ejected from the break would be expected to be vaporized whilein the form of droplets in the jet escaping from the break, the remainder would eventually evaporate with the soil and the air providing the necessary heat.Clearly the rate at which this fraction of the vapor is injected in the air isdetermined by:1)the amount vaporized in the jet and immediate vicinity. This fraction wouldform a mixture heavier than air which would at the same time disperse in the air and alsotend to settle into a "fog-like" ground layer. Since the instantly vaporized propane (amount flashing at break) would exhibit similar behavior, the fraction of propane liquid vaporized in the jet and immediate vicinity can be treated, at equilibrium, as additive to the constant vapor flow assumed for the initial dispersion calculation, which coupled itself with the treatment of just the flashed vapor.2)the amount of propane which remains liquid and experiences delayed evaporationat the ground.The rate of evaporation of the ground liquid depends on the area and depth ofthe liquid. Since this in turn is determined by terrain, precise assessment of this rate is extremely difficult. It seems reasonable to assume that an equilibrium condition can be established whereby a like amount of liquid evaporates as that which exists from the break. Less evaporation would result in an ever increasing area (or depth) of the liquid.

An estimate of the atmospheric clouds resulting from the delayed evaporation is presented below.Conservatively, however, it is possible to assume that all of the escapingpropane would be atmospherically dispersed. Under this assumption, the resulting maximum detonable cloud would be that established by a constant escape of approximately 1000 ft 3/sec of propane for the 8 in. line (Union Carbide) andapproximately 1/3 of that for the 6 in. line. For the maximum detonable cloud resulting from the 6 in. line, therefore, the contours shown in Figure 2.2-8 are applicable.

WSES-FSAR-UNIT-32.2-32In the previous calculation; the heavier than air density of the propanemixtures had not been considered, but the limit in vertical dispersion was implied in thechoice of z1/2 y characteristic of F stability conditions.Reference 2 recommends values of z 1/5 y.Table 2.2-21 and Figure2.2-9 shows the dimensions of the propane plume down-wind of the assumed 1000 ft 3/sec source, with z15/y.This detonation would then be equivalent to the detonation of 4.56 x 10 5 lb = 0.228 ktons of TNTassuming 100 percent yield.In actuality the yield will not be 100 percent. Reference 1 cites a yield of 7.5 percent. Work by Iotti, et. al.,shows that indeed the yield of a gaseous detonation is lower than that of TNT. References 5 compares overpressures calculated by assuming gaseous point sources(47) to overpressures obtained byKingery(64) for the same yield, and those measured by Kogarko, et. al.(38), for the given gaseousdetonation. This comparison shows that Kingerys result would have been comparable to those of References 63 and 65, if a TNT yield of 50 percent had been employed. Thus a conservative estimate of the TNT equivalent to the detonation of the entire cloud can be obtained by using 50 percent yield and use of Kingery charts, see Figure 2.2-10. Thus the hypothetical detonation of the entire propane discharged by the line would result in consequences similar to the detonation of 0.114 kT of TNT. This detonation however cannot occur, and more realistically the true detonation will be somewhere between the 13.5 tons and the 114 tons of TNT, but closer to the 13.5 tons.The 50 percent yield computed on the basis of the overall detonable mixture weight is a moreconservative method of evaluating the hazards from potential cloud detonations than that advocated by Reference 79. According to the latter, for instance, the detonation of the detonable cloud depicted in Figure 2.2-9 would be equivalent to the detonation of 73 tons of TNT as compared to the 114 tons computed by the method employed.Table 2.2-22 lists the pertinent shock wave parameters for the two yields. These parameters are obtainedfrom Reference 64, assuming that the center of the detonation is 1550 ft. from the plant for the 13.5 ton detonation, and 3600 ft. from the plant critical structure for the 0.114 kton detonation.Table 2.2-22 also lists the seismic parameters at the plant site due to air blast induced ground motions.These parameters are obtained from equations in Reference 37.Plant critical structures are designed so that they are able to withstand the overpressures and groundmotions listed in Table 2.2-22 hence it is concluded that the detonation itself of propane escaped from a break in the 6 in. or 8 in. LPG lines will not result in unacceptable consequences.Later on it will be shown that cloud expansion effects following the detonation, will also pose no hazards to the plant.

WSES-FSAR-UNIT-32.2-33e)Calculation of Flammable (Detonable) Cloud Size - Ground LayerFormation and Dispersion ModelThe model described hereinafter follows the formation of the cloud assuming that all of thepropane issues from the break as liquid, evaporates, and forms a cloud denser than air which then travels by gravity until it becomes neutrally buoyant, i.e., its travel velocity is equal to or less than the prevailing wind.For a continuous release rate of liquid propane W, the maximum pool radius rmax is determinedfrom the liquid pool area required to vaporize the LPG at a rate equal to the release rate, hence21fgf max B)hh(W r= (ft) (1)where B is the liquid evaporation rate determinable from the following equation(73),which is in metric units.8.0bg f w B 30 k h= (2)In the preceding equation , k, f ,g are the surface tension, the thermal conductivity, andsaturated liquid and vapor densities of propane at -44

This figure compares favorably with values which can be extrapolated from the Jacob experiments (73) on vaporization of propane from clean surfaces, and also with values reported in LNG studies (74). The initial height of vapor cloud which is input to the gravity spreading analysis from an initial radius r max, is computed by determining the amount of vapor injected in the air during the time it takes the prevailing wind to traverse the pool radius, if wind is present, hence (DRN 06-905, R15) fgf max inhh Br h (5) (DRN 06-905, R15)

The wind velocity, u, is additive to the radial spreading velocity upwind of the break, but subtractive downwind of it. Thus its net effect is ignored in (12a).

The choice of the entrainment coefficient a is prompted by data reported for plumes 75,76 and work by Lofquist (77). In Lofquist work, the important dimensionless parameters are the Reynolds number and the densimetric Froude number which he defines as F 2 (dR/dt)2gh - a (14)

He finds that even for very low Reynolds numbers (10

5) the entrainment is simply related to the F number and is independent of the Reynolds number. Figure 2.2-11 shows the values of a derived from Lofquist work. Examination of equations (9) and (14) shows that in our case, wherein ap=p c , F is always greater or at most equal to 2 since p c >p a and S is positive.

WSES-FSAR-UNIT-3 2.2-36 Revision 15 (03/07)

From the figure than a is taken as 0.1 larger. Values reported by others are also in the neighborhood of 0.1 to 0.12. Hence a value of 0.1 can be chosen as conservative (less dispersion to lower Propane concentrations).

In equation (16) C, and T are the cloud heat capacity and temperature at time t, C a and T a the air heat capacity and ambient temperature in °R Q w is the heat of condensation or freezing of any water vapor, which is set to zero in the interest of maximizing cloud travel. Q p is the heat content of the total propane at time t, which is computed from m p being the effluent rate in lb/sec and P 98 being the heat content of propane vapor at -44F referred to zero at °R. (DRN 06-869, R15)

Q g is the heat transferred by the ground to the cloud. To minimize heat transfer, it can be assumed that this heat is transferred in the natural convection regime, where Q h R(t) T - T(t) g 2 g (17) with h given by equation (3).

Equations (9), (15) and (16) are solved numerically given an initial cloud radius, r max , height, h in , and temperature, -44F, to yield the configuration of a homogeneous cloud as a function of time.

The progress of the cloud is either followed until the cloud concentration falls below the lower flammable limit (2.4 percent), assuming no atmospheric dispersion, or it can be stopped when the cloud velocity falls below the prevalent wind velocity at which point atmospheric dispersion would

be assumed to commence.

With this approach only average (time and space) cloud properties can be obtained.

Figure 2.2-12 shows downwind and downslope distances achievable by a cloud of 2.4 percent concentration of propane for different wind velocities. Also shown is the cloud final height at that

concentration.

These are for a variety of terrain configurations. The terrain configuration most resembling the Waterford site is that of open ground (i.e., large channel 1200 ft).

WSES-FSAR-UNIT-3 2.2-37 Revision 15 (03/07)

The results of Figure 2.2-12 which are obtained for an average ground slope of less than one percent show that under extraordinary conditions in which the wind velocity closely matches the cloud velocity, a ground confined cloud can travel long distances. Although molecular diffusion, which will take place between the air and the cloud has been ignored in the development of the previous equations, its contribution to decreasing the distance traveled by the cloud is not thought to be significant, except for the long distance clouds where it becomes the predominant

effect. (DRN 06-869, R15)

In most instances however, the cloud will travel a distance of six to seven thousand feet or less in relatively narrow channels, and less as the channel width increases. (DRN 06-869, R15)

The final cloud height is relatively insensitive to the wind velocity (under the assumption of no atmospheric dispersion) and is in fact very much determined by the break outflow. The final height is further very much affected by the channel width. For large channels like the Waterford

situation the cloud will not go far until atmospheric dispersion takes over.

The study also concluded that ground slope is not an important factor so long as it is limited to less than one to two percent. Much higher slopes would affect the results by increasing the

equilibrium cloud speed.

Except for the analyses performed for the low wind velocities, it was shown that the cloud velocity falls below the wind speed rather soon. From that point on, clouds traveling long distances can only be obtained by assuming that atmospheric dispersion does not occur. This would of course only happen if the air flow is laminar (i.e. no disturbance), a condition which is extremely unlikely.

Thus for Waterford it is concluded that atmospheric dispersion could dominate air-vapor

transport.

At the point in which the cloud speed falls to the level of the wind speed, the more realistic assumption can be made that atmospheric dispersion begins. The concentration downwind can

then be obtained from the equation for a continuous line source.

The virtual location of the line source is chosen upwind of the point at which the cloud and wind speed become equal, by solving the following equation X dR dt 2 2QuLs erf L/2 2 uudR dt z y(20)where X = dr/dt is the computed concentration, in volume fraction, at the time

in which the wind velocity equals the cloud velocity. In equations (18), (19) and (20) the

downwind distance does not appear explicitly, but is found by trial and error solution for z andy , the dispersion parameters which are functions of that distance. These are the same as those used in the previous section.(DRN 01-464)

Equation (18) has been used to calculate the width of a source and its

distance upward that would produce concentrations of 2.4 percent of propane at a point.

The results are shown on Figure 2.2-13 for both cases examined, i.e. y 2~z andy~ 5z.(DRN 01-464)

From this figure it is clear that for winds in excess of 2.6 fps, sources located upwind at distances larger than 5000 or 10,000 ft, cannot produce concentrations higher than 2.4

percent of propane. Lower wind speeds could. However Figure 2.2-12 shows that for these

low wind speeds the mass flow rate is large enough to result in significant entrainment prior

to atmospheric dispersion. Conversely where entrainment is low, atmospheric dispersion is significant. The combination of the Figures 2.2-12 and 2.2-13 therefore indicate that a

maximum credible cloud distance would be of the order of 5000 ft. These figures are of

course applicable to the release of 100 lb/sec characteristic of the 8 in. line.(DRN 01-464)

That these are the maximum credible distances is further confirmed by the fact that the time

required for the formation of such clouds is roughly comparable to the time required to isolate the

break, which is approximately 1/2 hour. To generate much larger clouds the flow of propane from

the break would have to continue uninterrupted at the assumed rate for much longer times.(DRN 01-464)

For these distances, no portion of the flammable cloud originating from the 8 in. line break would

reach portions of the plant structures. Intakes would not be expected to take up flammable vapors.

The same conclusion can of course be applied to the 6 in. break line.

The detonation of such clouds has been evaluated in the preceding sections and presents no hazard.f)Calculation of Deflagration HazardsThe possible hazards from the deflagration of the clouds are next addressed.

WSES-FSAR-UNIT-32.2-39 Revision 11-A (02/02)

A vapor cloud of flammable concentration may burn (deflagrate) or detonate (if within the detonable limits) or both types of combustion may occur in case of transition from deflagration to detonation. Volumetric explosions may also occur, particularly, if partial confinement of the cloud exists. More likely pockets of gas in a cloud may explode volumetrically if heated to the

autoignition limit by radiated heat or shock waves.In general, therefore, one should consider deflagration, detonation, and volumetric explosion to be the common modes of combustion. In our case due to the unconfined nature of the cloud the latter mode cannot occur, and it is only necessary to address detonations and deflagrations.

For detonations all of the thermodynamic properties, detonation velocities and flow properties behind the

detonation front are calculable from standard thermodynamic equilibrium calculations.(DRN 01-464)

If one defines as U 1 and U 2 the velocity of the unburned gas and burned gas with respect to the stationary detonation wave, then with respect to a stationary observed U, U is the detonation velocity and W =U 1 - U 2 is the velocity of the gas behind the detonation wave front.

(DRN 01-464)

Further the thermodynamic states behind the detonation front are described by the Hugoniot equation

))((2 1211212vvppEE DE+wherein p and v are the pressure and specific volume and E the energy and 1 and 2 denote the unburned and burned states respectively.(DRN 01-464)The actual detonation involves a passage through a family of Hugoniot curves, which proceed from the curve corresponding to no chemical reaction wherein E = E 2 - E 1 = C v (T 2-T 1), C v is the average specific heat at constant volume between temperatures T 1 and T 2 before and after the passage of the wave front to the curve corresponding to complete chemical reaction in which case(DRN 01-464)

-.E- E CT- T-21v21cwhereinE c is the energy released in the combustion process.

Figure 2.2-15 shows both Hugoniot curves. The Hugoniot curve for the complete reaction is distinguished by two branches. The branch from A to V is the "detonation" branch and the one from B to C is the"deflagration" branch. It has been shown that the only possible state detonation is the detonation proceeding at the minimum detonation velocity (see Reference 80). This is the Chapman Juguet detonation

and the resulting detonation overpres sure can be found by running a tangent line to the detonation branchfrom the original condition. The resulting C-J overpressure for stoichiometric propane air mixture has been determined to be p 2/p 1 = 17.8 from an initial state of 14.7 psi and 460

°F.

WSES-FSAR-UNIT-32.2-40That value is closely correspondent to that reported by J. H. Lee (Reference 81). Point A corresponds tothe overpressure resulting from a adiabatic constant volume explosions. The value obtained of p 2/p 1 =8.5 differs slightly from that quoted in various references including Reference 1, which reports 8.34. Thedifference is due to the initial state assumed for these calculations which was 0

°C, whereas othersgenerally used 25

°C.The intersection of the tangent line with the Hugoniot curve for no reaction is the Von Neumann spikewhich precedes the C-J detonation pressure. Its computed value is approximately p 2/p 1 = 28, again inclose agreement with values reported in the literature.The detonation velocity which is given byUDv p-pv-v 11 21 12(23)is computed to be D = 5330 fps or 1610 mps, which is in reasonable agreement with literature data.In the detonation branch the flow velocity of burned gas, W, is in the same direction as the detonationwave. In fact it can be shown that (Reference 82)D = W + C (24)where C is the velocity of sound in the burned medium.Since the detonation wave travels supersonically with respect to the unburned medium, no disturbanceprecedes it, hence the cloud size remains at its initial size as the detonation propagates, i.e. the gas expansion occurs afterwards and has the effect of a rarefaction wave which tries to overtake the detonation wave at sonic velocity in the burned medium. This observation has been made by others (Reference 81, page 12). Further discussion of the subsequent expansion is given later on.Thus the effects of the detonation blast of the wave of the propane gas clouds has already been properlyaddressed in the preceding subsections.The portion of the curve between A and B corresponds to no real physical state. The portion of theHugoniot curve between B and C represents a decrease in pressure and increase in volume, corresponding to a rarefaction.The burned gas flow velocity, W, therefore is always negative, i.e. the burned gas no longer moves in thesame direction as the wave, but away from it.The consequence of this is that in this deflagrative process a precompression wave is sent out into theexplosive mixture to push that unburned gas with a velocity just sufficient to ensure that the gas may come to rest when it is swept over and burned by the deflagration front.

WSES-FSAR-UNIT-32.2-41Physically no deflagration occurs past the point C (Reference 80) which is known as a Chapman Jougnetdeflagration point. In fact weak deflagrations (essentially constant pressure explosions) are those to be considered for vapor clouds explosions, and are the ones that have been observed in experiments.Whereas the C-J detonation velocity represents the minimum of all detonation velocities, the C-Jdeflagration velocity is in fact the largest possible deflagration velocity, which is calculable from equation (24).For the propane-air mixture studied (stoichiometric) the C-J deflagration velocity was computed to be 168fps.For weak deflagrations however the deflagration velocity is the same as the laminar burning velocity, 1.5-2.0 fps, hence thousand times less than detonation velocities.However the spatial deflagration velocity, which would be that seen by a stationary observer is higher thanthe deflagration velocity computed by equation (23). This is due to the displacement of the unburned gases ahead of the propagating flame caused by the specific volume increase across the flame front.

Since this increase is about eight fold, the spatial deflagration velocity is roughly eight times that computed by equation (23).Hence for a C-J deflagration spatial velocities of the order of 1300-1400 fps could occur. In actual testshowever (References 79 and 83) the spatial flame velocity has been measured to be of the order of 30-40 fps, for mixtures difficult to detonate (like propane air) and ten times larger for mixtures rich in oxygen.The effect of oxygen richness is not surprising since lack of inerts such as nitrogen has the effect ofraising the Hugoniot curve for complete reaction to higher values. For instance the C-J detonation point for a stoichiometric propane-oxygen mixture would correspond to overpressure almost exactly double that occurring for the detonation of propane-air mixtures, with detonation velocities 30 percent higher.

Similarly the C-J deflagration velocities for oxygen rich mixtures is expected to be higher than that for propane-air mixtures.Hence C-J deflagrations of any kind exhibit velocities in excess of 1300 fps. The fact that no such spatialburning velocity has been observed confirms that C-J deflagrations do not occur, but that only weak deflagrations, i.e. basically constant pressure burning occur.For these kind of deflagrations, the precompression sent into the unburned medium and surrounding air isin the nature of basically an acoustic wave. It does not steepen into an air shock unless spatial flame velocities of 300 fps or more are achieved, as shown on Figure 2.2-16 (taken from Reference 81).Likewise there is no overpressure of great significance within the deflagrating cloud. For typical spatialburning velocities of 30 fps or less, overpressures of about 1 psi will occur just ahead of the flame front.

Hence it is concluded that blast damages are insignificant for deflagrative burning of propane air clouds either near or far from the cloud. Hence for a deflagration the possible damage is limited to temperature.

WSES-FSAR-UNIT-32.2-42 Revision 11-A (02/02)

In a detonation event, after passage of the initial detonation blast, the compressed products expand. Under the assumption that this expansion is isentropic, the final volume will be approximately 9.7 times initial

volume (assuming K = 1.25) (for an oxygen rich detonation these rates would be more than double). This

expansion in turn can generate a second shock in the air ahead of the expanding products of the detonation, which follows the initial shock caused by the hydrodynamic coupling of the detonation wave and the air.

This second shock is one order of magnitude smaller than the first air shock (see Reference 38) and exhibits the same decay with distance from the center of detonation as the first and much stronger shock.

Since the Waterford plant has been shown to withstand the first shock overpressures, it is also safe against the weaker second shock caused by the expanding detonation products.

During the preceding it has been tacitly assumed that the flammable cloud is entirely formed of a stoichiometric mixture of propane and air (or oxygen). This was of course the case for all experiments

conducted (see References 38,79,81,82). In fact, the computed propane air clouds as shown on Figures

2.2-8 and 2.2-9 exhibit a range of mixtures which are only stoichiometric in a region which at ground level is

centered about the 1300 ft and 3500 ft from the origin of the cloud. At closer distances to the origin of the

cloud, ground level concentrations are overrich and farther away they are leaner than stoichiometric.

Since the propane plume downward of the 1000 ft 3 /sec source is shown to present the greatest hazard to the plant, Figure 2.2-9 has been modified to reflect the larger span of mixture conce ntrations within which a deflagration can occur. Whereas the detonable limits for propane air mixtures are 7.0 and 2.8 percent by volume of propane, the limits of deflagrations are 9.0 and 2.2 percent.

The volume of flammable mixture contained within the vapor cloud shown on Figure 2.2-9 is computed to be 1.95 x 10 7 ft 3 , whereas the detonable volume is only 1.15 x 10 7 ft 3.Hence 40 percent of the total flammable volume has concentrations below 2.8 percent, or below 0.7 times

the stoichiometric concentra tion of 4.12 percent.(DRN 01-464)

The expansion of a mixture of less than 67 percent stoichiometric concentration (as well as that of concentrations above 120-130 percent of stoichiometric mixtures) is at least 30 percent less than the

expansion of stoichiometric mixtures. This results basically from the lower flame temperature. The

expansion given on Figure 2.2-15 as point B is thus applicable only to stoichiometric concentrations.

Conservatively therefore the final volume of the de-flagrated vapor cloud can be estimated by expanding the

volume of 2.8 percent or larger propane concentration to a final volume eight times larger, and the volume of

lower concentration to a volume 5.5 times larger. The resultant final volume would be 1.35 x 10 8 ft 3.(DRN 01-464)

Assuming that the original cloud can be represented as a hemiellipsoid of 4564 ft, 143 ft, and 28.6 ft in the

downwind, crosswind and vertical direction respectively, centered at 2734 ft from the break, and that the

deflagration is centered at that point, the final dimension of the product cloud downward will be 6717 ft from

the break.

WSES-FSAR-UNIT-32.2-43 Revision 11-A (02/02)

The closest distance from the 8 in. pipeline to a safety structure in Waterford 3 is 7350 ft. Hence it is concluded that the deflagration of the "worst" cloud ensuing from a catastrophic break in such a line poses no hazard to the plant.g)Summary Conclusion To summarize the preceding sections, the transport of propane clouds toward the Waterford 3 site has been investigated from a purely at mospheric dispersion standpoint, gravity slumping, and a combination of atmospheric dispersion and gravity slumping.

Although the analyses demonstrate that it is possible for a flammable cloud to form in the vicinity of the plant site, deflagrations, fires or detonations of the cloud will pose no hazard to the plant.

2.2.3.1.3.3 Stationary Sources Presenting Explosive Hazards(DRN 01-231)

Table 2.2-3 indicates the types, quantities and locations of potentially hazardous materials as they are presently known (refer to Appendix 2.2A.1 for a historical assessment of hazards from Acrolein in tanks).

Not all information has been located for the Union Carbide Company. However, Union Carbide has identified

the two potentially most hazardous sources of material, and these have been listed. Of these two, the

propylene tank which can contain as much as 5.78 x 10 6 lbs of propylene is the worst hazard and is located closest to the plant. Except for this tank, on the basis of the information presented in Table 2.2-3, the

detonation of butene- 1 in the largest tank (assumed to be located approximately 6300 ft from the Waterford plant) has been determined to be the most severe realistic hazard. The detonation of the tank filled with

butene-1 in concentrations within the flammable limits (1.6 to 9.3 volume percent in air) would correspond to the detonation of approximately 500-1000 lb of detonable mixture. Assuming 100 percent equivalency with TNT, the detonation of this mixture poses no hazard to the Waterford plant in terms of blast overpressures.

From the work of Ahlers, shown on Figure 2.2-17, missiles and debris accompanying such detonation would also present no hazard.(DRN 01-231)

In addition, even though ammonia is not considered as a detrimental flam mable/explosive material by the U S Dept. of Transportation, theoretically ammonia can ignite. Hence the hazards to the Waterford plant from

the large liquid ammonia tanks located 3200 ft. away for the closest 10,000 ton tank and 4225 ft. away for

the prospective 45,000 ton tanks have also been examined. In either case peak overpressures resulting

from the detonation of the tanks (assumed to be full of detonable mixture of NH 3 and air) have been computed to be less than 1 psig, and missiles resulting from such event are on the average expected to fall

short of the distance to the plant (from Ahlers work). Hence these tanks also present no hazards to the

Waterford plant.

The relative closeness to the plant coupled with the very large size of the propylene tank deserves more consideration.

This tank is located in the northwest section of the Union Carbide plant. Although the exact location is not known, it is reasonably certain that the tank is no closer than 7400 ft. to safety related structure and

components of the Waterford 3 plant.

WSES-FSAR-UNIT-32.2-44Utilizing the methodology of Reference 79, the hazards to the plant resulting from the detonation of theentire tank contents can be evaluated, to assess very conservatively the upper limit of the effects of the tank detonation. Per Reference 79 the TNT mass equivalency of propylene is 225 percent. Even under the unrealistic assumption that the entire 5.78 x 10 6 lbs of propylene detonate, this detonation, whichwould be equivalent to the detonation of 6500 tons of TNT would result in a computed overpressure at the plant of 1.0 psi. A more realistic evaluation, which would consider that air needs to be mixed with propylene to form a detonable mixture, would indicate a yield of less than one tenth of the above. Hence the detonation of the propylene tank in situ, presents no hazard to the plant.The hazards presented to the plant by a vapor cloud that might be formed as a result of the tank failure,with delayed ignition of the cloud are studied below.Since the break area of the tank cannot be known, the hazards from such postulated events have beenassessed for a number of breaks ranging from a catastrophic failure instantly releasing most of the contents of the tank, to a break size which would result in a release of 100 lb/sec. The latter was chosen since the hazards to the plant from similar propane sources, located at virtually identical distances, have been assessed and found to be acceptable.According to Union Carbide only 2,600,000 lbs of propylene vapor can be released to form a cloud. Thecatastrophic failure of the tank, resulting in the instantaneous release of the 2.6 x 10 6 lbs is evaluated byfollowing the gravity slumping of the ensuing cloud. The method used in Section 2.2.3.1.3.2.e) has been modified to account for instantaneous sources following the methodology of Reference 74.The radius of the spill prior to gravity spreading is computed from equation (7), wherein the liquidregression rate, Q, is given by equation (8). For propylene, which has a boiloff rate of approximately 30,000 BTU/ft 2 hr, and a heat of vaporization of 180 BTU/lb, the liquid regression rate can be computed tobe 3.8 x 10

-4 mps. The instantaneous spill would then result in a pancake shaped cloud having an initialradius of 470 ft, and an initial height of 25 ft. This cloud expands as it slumps under its own weight. For the terrain configuration around the tank and the Waterford plant this expansion will be essentially a pure radial expansion.The velocity with which the cloud advances is computed from equation (9) wherein the ground slope effectis neglected since it is minimal and in fact would tend to draw the cloud away from the plant. The amount of air which is entrained by the cloud surface as it advances is computed from equation (12a).Solution of the mass and energy conservation equations (equations 15 and 16, respectively) yield theconfiguration of a homogeneous cloud as a function of time.For the instantaneous spill resulting from the catastrophic tank failure, the radius of the cloud having ahomogeneous lower flammable limit concentration is calculated to be 2440 ft.The velocity of the cloud front at this time is 6 fps, which is still higher than the condition F meteorologywind speed of 2.6 fps. Hence gravity slumping is the dominant mode of dispersion. From the analyses of Subsection 2.2.3.1.3.2 f), it is clear that the WSES-FSAR-UNIT-32.2-45Revision 8 (5/96)deflagration of this cloud would pose no hazard to the plant. Likewise detonation effects present nohazard.For breaks which are intermediate between the catastrophic and that resulting in 100 lb/sec it has beencalculated that the clouds of similar composition are not as extensive, i.e. more of the propylane disperses past the lower flammable limit. Hence they present less hazards to the plant than those resulting from a catastrophic break.A similar observation has been made by Reference 74. It is therefore concluded that the propylene tankpresents no hazard to the plant safety structures and components.2.2.3.1.3.4Hazard Assessment of the Air Products Hydrogen Pipeline ProjectIn the Fall of 1994 construction started on the Air Products and Chemicals, Inc. hydrogen pipeline project.This pipeline transports hydrogen from the Dupont Chemical, Inc. plant in Reserve to the Union Carbide Corp. plant in Taft. The 12.75 inch diameter pipeline enters the LP&L property to the southwest of Waterford 3, just south of the Union Pacific Railorad tracks. The pipeline then runs parallel to the railroad tracks and exits the LP&L property to the southeast of Waterford 3. There are no above ground sections of the pipeline on the LP&L property. The pipeline is buried to a minimum depth of five feet on the LP&L property. The closest above ground section of the pipeline is 3200 feet from the eastern boundary of the LP&L property. The estimated flow rate of hydrogen in the pipeline is 36.48 (10) 6 scf/day. References101 through 105 provide a detailed description of the pipeline.Key parameters related to the explosion of the new hydrogen pipeline were compared to key parameterrelated to the explosion of the Evangeline Natural Gas Pipeline (FSAR Section 2.2.3.1.3.1.2), at the pig trap station, to show that the explosion effects associated with the new hydrogen pipeline are much less severe than the explosive effects of the Evangeline Pipeline. Reference 106 shows the detailed comparison.The key parameters that were compared are:1.Size of the explosive cloud, based on the major semiaxis of the lean ellipsoid.

2.Distance from the center of mass of the explosive cloud to the Waterford 3 safety relatedstructures.3.Specific heating value of the air/gas mixture.The results of the comparison were that:1.The explosive cloud from the hydrogen pipeline rupture is much smaller than the cloudfrom the Evangeline pipeline rupture. The lean hydrogen cloud from a pipe break isapproximately slightly more than one third the size, based on the major semiaxis, of the lean natural gas cloud from the Evangeline pipeline break.2.The distance from the center of mass of the hydrogen cloud to the Waterford 3 safetyrelated structures is much greater than the distance from the center of WSES-FSAR-UNIT-3 2.2-46 Revision 14 (12/05)mass of the natural gas cloud to the safety related structures. The distance from the center of the explosion to the safety related structures for the hydrogen pipeline is slightly greater than double the

distance for the Evangeline pipeline. 3. The specific energy liberated from the stoichiometric combustion of both the hydrogen/air mixture and the natural gas/air mixture is identical. The consequences of the potential hydrogen pipeline break and explosion are therefore less severe than the consequences of the break and explosion of the Evangeline natural gas pipeline, at the pig trap station. The allowable overpressure, on the Waterford 3 safety related structures, is 3.0 psi (design basis). The design basis overpressure event is the LPG tank truck explosion, on highway 18, as presented in FSAR Section 2.2.3.1.2. The maximum overpressure from an explosion on the Evangeline pipeline, at the pig trap station, is slightly less than 1.0 psi. The overpressure from an explosion on the new hydrogen pipeline would be much less than 1.0 psi, as shown above. It is thus concluded that the potential hazard posed by a break and explosion of the new hydrogen pipeline is well within the design basis of the Waterford 3 safety related structures and is in fact bounded by previously analyzed explosive

events.2.2.3.1.4 Potential Hazards From Externally Generated Missiles (DRN 03-2055, R14;05-149, R14) A review of hazardous chemicals which have a potential for generating missiles, that may arrive at the plant, shows that there are no events that may cause any damage to the plant which would result in

radionuclide release in excess of 10CFR50.67 guidelines. (DRN 03-2055, R14;05-149, R14) All railroad lines in the vicinity of Waterford 3 have been considered in order to determine whether a "rocketing" tank car event could pose any threat to safety-related structures. The closest rail line which carries explosive materials is located at a distance of 0.45 miles (2375 ft.) from safety-related structures.

This distance as greater the ranges of fragments of the train accident in Laurel, Mississippi (41). The range of the "rocketing" car in Laurel, Mississippi, accident was 1100 ft. while small fragments had a maximum range of 1600 ft. Thus there are no hazards from "rocketing" rail cars or their fragments, for

the Waterford 3 safety-related structures. A spectrum of events was considered in analyzing the trajectories of externally generated missiles. The cases of deflagrative explosions for the 300,000 bbl. gasoline tanker and the 10,500 gal. LPG truck were discussed above. Detonations which propel missiles which are not fragments (of the tanks containing the

explosives) were also considered. Detailed analyses show that for a missile spectrum which consists of a wooden plank, a three in. diameter schedule 40 steel pipe, a 12 in. diameter schedule 40 steel pipe, a utility pole and one in.

diameter reinforcing bar, the conservative limiting case is encountered when an overpressure wave picks

up a 12 in. diameter, 15 ft. long pipe at the site boundary and propels it towards the plant. The impulse delivered to the missile is calculated by obtaining the overpressure (due to the detonation) at the location where the missile is picked up, and multiplying it by the cross sectional area of the missile and by the positive duration (stagnation time) of the overpressure wave at that location. The speed of the

missile is then obtained by dividing WSES-FSAR-UNIT-32.2-47 Revision 11-A (02/02) the impulse by the mass of the missile. For conservatism the actual speed of the missile was multiplied by a factor of two and the modified value was used in calculations.

The velocities of impact at walls and roofs of safety-related structures were obtained by numerically solving the standard ballistic equations (42).

Comparison of the Waterford 3 results and EPRI data (43) show that since all walls and roofs of safety-related structures are at least two ft. thick, and the concrete strength is at least 4000 psi (28 day crushingtest), there is no danger of penetration and/or spalling of walls and roofs of safety-related structures caused

by missiles picked up by overpressure waves.

2.2.3.2 Delayed Ignition of Flammable Vapor Clouds A combustion wave propagates by the process of heat transfer and diffusion, whereas a detonation wave is a shock wave which is sustained by the energy of the chemical reaction initiated by the temperature and

pressure of the shock wave. Thus in order to have a detonation certain conditions are necessary in order to

form shock waves.

These conditions are inherently absent in free clouds (confined space may result in shock formation) and thus the probability of a detonation is extremely low. It is nevertheless possible that a detonation can be set

off by shock waves generated either at a pipe break location as a result of the sudden decompression, or at openings in structures where deflagration has taken place. The former cannot result in a significant

detonation since very little vapor would have escaped the break.

Deflagration, rather than detonation, of a flammable cloud would result in lower overpressures and dynamic pressures at the safety related structures. Such a firestorm and associated winds, would not cause

damage due to overpressures.

The size and duration of fireballs is given by Strehlow and Baker (44) as D = 3.86 W 0.32 (diameter in meters) t = 0.299 W 0.32 (duration in seconds)

Where W is the weight in kilograms.

In the case of the LPG tank truck, it is conservatively assumed that the entire load vaporizes. The resulting propane cloud weighs.

2.2lbm lkg x propane)(liquid 3 lbm/ft 36.2 x gal 3 ft 0.1337 x gal 10,500 W=kg 4 10 x 2.3=(DRN 01-464) the diameter would be D = 3.86 x (2.3 x 10 4)0.32= 96 meters = 315 ft, and the duration of the(DRN 01-464)

WSES-FSAR-UNIT-3 2.2-48 Revision 301 (09/07) fire would be t = 0.299 x (2.3 x 10 4)0.32 = 7.44 sec.

If the cloud were to travel towards the plant and burn for the 7.44 seconds, it will get only 19.34 ft. closer.

Thus conservatively assuming that the cloud ignites at the location of accident, (36) and that it travels 19.34 ft, it will still be approximately 125 ft. away from safety-related structures.

To calculate the heat load on the plant from a propane cloud 125 ft. away, the relation for radiation heat

flux is used. (DRN 01-464, R11-A)

Q = , (T 4 f - T 4 ambient) where , = 1.714 x 10

-9 BTU/hr ft 2°R 4 and a conservative flame temperature (17)

T f of 2198K, while T ambient = 70F or 529.7R. (DRN 01-464, R11-A)

Q = 1.714 x 10

-9 BTU/hr-ft 2-R 4 [(2700)4 - (529.7) 4] R 4 = 4.18 x 10 5 BTU/hr-ft

2.

Thus, under conservative assumptions, where no credit for attenuating factors is taken, the heat load on

the wall is 4.18 x 10 5 BTU/hr-ft 2 = 116.34 BTU/sec-ft.

2 , for the short duration of 7.44 seconds. This will cause surface skin-heating effects on the outside walls, but the short durations involved will not compromise the integrity of any safety-related structure. (DRN 01-464, R11-A;05-149, R14) The deflagration of a propane vapor cloud does pose a hazard from rapid combustion or deflagration, and resulting effluent generation. However, it does not place the integrity of safety related structures in jeopardy, and cannot result in radionuclide release in excess of 10CFR50.67 guidelines and as such, it is not considered a design basis accident. Other sources of flammable vapor clouds are considered to present lesser hazards due to greater distances from the site and the conservatisms of the propane

vapor cloud analyses. (DRN 01-464, R11-A;05-149, R14) 2.2.3.3 Design Basis Toxic Chemicals (EC-5000082218, R301)

Information regarding the storage, transport and use of materials cited in Tables 2.2-3B through 2.2-3G, 2.2-5, and 2.2-6 indicates that there are several sources for release of toxic chemicals which have a potential for adversely affecting main control room habitability. In addition to chlorine detectors, a Broad Range Gas Detection System (BRGDS) has also been provided which is capable of detecting airborne concentrations of various organic and inorganic compounds. A discussion of the BRGDS has been presented in Subsection 6.4.4.2. The presence of detectable chemicals at the air intakes would trip these detectors resulting in the sounding of an alarm and the automatic isolation of the control room. The accidental releases of toxic gases from onsite and offsite facilities have been analyzed in detail and

determined to pose no threat to control room operators.

Following guidance in Regulatory Guide 1.78 (June, 1974), consideration was limited only to those chemicals which are present within a distance of 5 miles from the main control room air intakes. The calculations were performed for the entire range of meteorological conditions presented in Section 2.3, and were based on main control room characteristics which are described in Section 6.4. (EC-5000082218, R301)

WSES-FSAR-UNIT-3 2.2-49 Revision 301 (09/07) 2.2.3.3.1 Volatility and Chemical Stability of Toxic Chemicals in the Air (EC-5000082218, R301)

Chemicals that are nonvolatile solids or liquids, or that spontaneously combust in air do not pose a threat to control room habitability. Consideration of these factors led to the elimination of many chemical sources from toxic hazard evaluation. The relevant physical and chemical data were obtained primarily from Sax's Dangerous Properties of Industrial Materials (45), the CRC Handbook of Chemistry and Physics (46), Langes Hanbook of Chemistry (110), and Perrys Chemical Engineers Handbook (111). Substances such as sulfur were eliminated because they are solids. Aqueous solutions of nonvolatile solids such as sodium hydroxide were eliminated because, while the solvent may evaporate, the solute is nonvolatile. Chemicals with vapor pressures of less than 10 torr (mm Hg) at 100F were eliminated, since Regulatory Guide 1.78 does not require consideration of such chemicals. (DRN 01-464, R11-A)

Other toxic materials were eliminated on the basis of RG 1.78, Table C-2. This was done by comparing the toxicity of the chemical, either on the basis of its IDLH value (if listed), the lowest toxic threshold

concentration listed by Sax (45) or information in the Material Safety Data Sheet and other sources. When data was not available, the toxicity limit was estimated by one of the methods described in

NUREG/CR-1741 (94) or in Reference 112. The Waterford 3 control room satisfies the requirements for Type B for those chemicals which can be detected by the BRDGS, and for Type C for those which cannot. The initial elimination screening was based on the assumption that the chemicals would not be detected and, consequently, the sources of toxic chemicals were compared in the quantities for a Type C control room. The Waterford 3 control room has an air exchange rate of approximately 0.86 volumes per hour as compared with a value of 1.2 volumes per hour for the Type C control room considered in RG 1.78. The worst 5 percentile meteorology for the Waterford site corresponds most closely to Pasquill

stability class G for which a multiplier of 0.4 is required by RG 1.78. Using these facts and adjusting for the toxicity of the specific chemicals if different than 50 mg/m 3 as used in Table C-2 of RG 1.78, the minimum quantity of each chemical that required consideration, according to RG 1.78, was then

determined and compared to the maximum amount stored. (DRN 01-464, R11-A; EC-5000082218, R301) 2.2.3.3.2 Methods of Assessing Accidental Releases of Volatile Toxic Chemicals

Assessments of control room habitability following accidental releases of volatile toxic chemicals were

performed for vapors that are heavier than air, both the release and the receptor of which are to be at ground level. For lighter-than-air gases and vapors, the release is assumed to be at the same elevation as the control room outside air intake. The methods of analysis followed the general guidance of Regulatory Guides 1.78 and 1.95, and utilized the detailed release and atmospheric transport model described in Reference 86. The general features of the analyses are described below.

(DRN 01-464, R11-A; 02-87, R11-A; EC-5000082218, R301)

For stationary and mobile sources, the assumption was made that the largest container of a given toxic chemical at a particular site fails and instantaneously releases all of its contents into the environment.

For chemicals whose boiling points are below their storage temperatures, the fraction which flashes was calculated from a heat, or enthalpy, balance. The rate of vaporization of the remaining liquid was determined by evaluating the rate of heat transfer into the liquid from the ground, air and solar radiation.

If the boiling point of the liquid is higher than the ground temperature, the evaporation rate is calculated on the basis of the vapor pressure of the liquid, the wind velocity and the surface area of the spill. This area depends on the mass of the liquid as well as the topographical characteristics of the spill site. For example, a retaining wall may restrict the spread of liquid released from a stationary tank, and a drainage ditch may contain a spill from a truck. Since, in most cases, the surface of the ground cannot be described accurately or predicted in advance the area of the spilled liquid was calculated according to

Van Ulden.

(51)(86) In those cases where the stored chemical was surrounded by a dike adequate to contain the entire volume of a possible spill, the area of the spill was restricted to the area of the dike. (DRN 01-464, R11-A; 02-87, R11-A; EC-5000082218, R301)

WSES-FSAR-UNIT-3 2.2-50 Revision 301 (09/07)

(DRN 01-464, R11-A; 02-87, R11-A) (DRN 01-464, R11-A; 02-87, R11-A)

The liquid which remained after the initial flash was assumed to be in the form of a right circular cylinder with a radius equal to its height. Under the force of gravity, liquid is assumed to spread radially, its area

being given by:

A(t)r+ 2tg V-o o12 1 12/ and V r oo 3 Where:

r o = initial radius of the spill (cm)

g = gravitational constant = 981 cm/sec 2

V o = volume of liquid remaining after initial flash (cm

3) 1 = density of that liquid (g/cm

3)

= density of air (g/cm

3) t = time (sec)

(EC-5000082218, R301)

The area of the spill is assumed to increase linearly with time until the liquid reaches a depth of 1.0 cm, or until the area equaled the area confined by the dike. Spill areas calculated by the above equation are much greater than the sizes of spills which the U.S. Department of Transportation expects to actually

occur.(52) Thus, the calculated evaporation rate is much greater than that which would occur following an actual spill.

The atmospheric transport and dispersion of the initial puff was calculated according to the general model presented in Regulatory Guides 1.78 and 1.95. The transport and dispersion of the continuous plume

evolving from the surface of the spilled liquid was calculated by the model presented in Reference 86.

This reference also contains a detailed discussion of the entire release and atmospheric transport model.

The short-term Pasquill-Gifford dispersion coefficients were calculated by formulae presented in Reference 95. For heavier-than-air gases, both the intake and the release were assumed to be at ground level; however, the concentration at the intake was assumed to be no greater than that which would result if the gas were uniformly dispersed in the vertical direction up to the level of the intake. (EC-5000082218, R301)

WSES-FSAR-UNIT-3 2.2-51 Revision 301 (09/07)

(EC-5000082218, R301)

The models described above were used to calculate concentrations of toxic chemicals outside the main control room air intakes. This was done for the entire range of meteorological conditions presented in

Section 2.3 (EC-5000082218, R301)

The concentration of a toxic chemical inside the main control room was calculated from the following

equation:

C (t) e ve X (t') dt'-vtvt'0 o t Where:

C (t) = chemical concentration inside the main control room at time t

X (t') = chemical concentration outside the air intake at time t'

v = Main control room air exchange rate

The toxic chemical concentrations calculated inside the main control room were assessed against their

'Immediately Dangerous to Life or Health' (IDLH) concentrations, which represent a maximum level from which one could escape within 30 minutes without any escape-impairing symptoms or any irreversible

health effects.

(87) 2.2.3.3.3 Evaluation of Stationary Chlorine Sources (DRN 01-282) Potential hazards posed by stationary sources of chlorine were evaluated by comparing such sources to

the allowable quantities listed in Table 1 of Regulatory Guide 1.95. For the purpose of applying this

Guide, Waterford 3 was assumed to have a Type II control room. Waterford 3 control room has local detectors, a normal air exchange rate of 0.66 vol/hr, (vs. 1 vol/hr in the Guide), and a measured leak rate of less than 0.06 vol/hr. The response time of the chlorine detectors is a function of the instantaneous chlorine concentration as well as ambient temperature. A calculation of the concentration build-up following a postulated release under various conditions indicates that the isolation time is less than or equal to 4 seconds, which is the isolation time stipulated by RG 1.95 for a Type II control room. (DRN 01-282) The stationary source of chlorine posing the greatest potential hazard is a tank on the site of the Occidental Chemical Co. (Oxychem), which contains 400 tons and is located 1506 meters from the Waterford 3 control room. At this distance, the maximum allowable quantity calculated by log-log interpolation, in accordance with the guidance of RG 1.95, is 685 tons. A 600 ton chlorine tank at a distance of 1677 meters is also located at Oxychem; the maximum allowable quantity at this distance is 967 tons. The Waterford 3 control room therefore satisfies the guidance of RG 1.95.

The only mobile sources of chlorine posing a potential hazard are tank cars transported on the tracks of the Union Pacific Railroad. These were evaluated along with other toxic chemicals transported on the

railroad, as discussed in Subsection 2.2.3.3.5.

WSES-FSAR-UNIT-3 2.2-52 Revision 301 (09/07) 2.2.3.3.4 Evaluation of Other Stationary Toxic Chemical Sources The analysis of postulated accidents involving stationary sources of chemicals other than chlorine were performed in accordance with the guidance of RG 1.78, using the methods described in Subsections 2.2.3.3.1 and 2.2.3.3.2. The analyses modeled the detection of chemicals required to be monitored by the BRGDS. In case of a serious accident, operators were assumed to don breathing apparatus two

minutes after the alarm.

(EC-5000082218, R301)

Several of the respondents to the 2004 survey provided the location of the potentially hazardous sources on their plant plot plans or on the U.S. Geological Survey map of the area. In those cases, the distance from each source to the control room air intake was measured directly from the map. In other cases, the site was divided into zones, and the zone number of each source was given. In such cases the source was assumed to be located at the zone boundary nearest to the control room. Lacking more specific information, the source was assumed to be in the center of the facility. (EC-5000082218, R301)

To model the seasonal variation of ambient temperatures, 12 sets of data, one for each month, were constructed. Each data set included the 49 combinations of stability class and wind speed found in FSAR Tables 2.3-126 to -132. Stability classes E - G occur primarly at night. To calculate the average nighttime temperature, it was assumed that the temperatures at night are lower than the mean temperature for the entire day. It was also assumed that the nighttime temperature varied uniformly

between the minimum temperature and the 24-hour mean temperature. Taking the average of these two

temperatures yielded an approximate average nighttime temperature. The average ambient nighttime

temperature for each month was thus calculated by taking the average of the mean temperature and the

mean minimum temperature for each month, using data in FSAR 2.3-33. Since stability classes A-D may occur in the daytime, average daytime temperatures were calculated for those cases by substituting mean maximum for mean minimum temperatures in the process described above. Daytime ground temperatures were assumed to be 10 C higher than air temperatures while nighttime ground temperatures were assumed to be the same as the air temperatures.

The frequency of occurrence of a given set of meteorological parameters for a given wind direction was calculated as follows. Each value of the annual average joint frequency of wind speed and stability class, found in Tables 2.3-126 to -132, was divided by the fraction of time the wind was in that sector (i.e., the

joint frequencies for the given compass direction were normalized to 1). Thus, each new value represented the probability of the joint occurrence of that particular wind speed and stability class

combination, assuming the wind is in the given sector.

Accidents under each set of meteorological conditions for the given wind direction were then modeled.

The control room was assumed to be habitable if the concentration inside did not exceed the IDLH Level

by the time the operators were assumed to have donned breathing apparatus (two minutes after the alarm). If the control room was habitable under meteorological conditions occurring not less than 95% of

the time for the given compass direction, the given source does not pose a hazard, according to the

guidance of RG 1.78.

WSES-FSAR-UNIT-3 2.2-53 Revision 307 (07/13) 2.2.3.3.5 Analysis of Transient Sources (EC-5000082218, R301)Transient sources (chemicals transported by truck, bar ge or rail in the Waterford 3 vicinity) were first analyzed in the same manner as the stationary sources.

The release was postulated to occur at the point on the road, river channel or rail line closest to the plant. For those postulated accidents for which the habitability criteria discussed above were not met, a probabilistic risk analysis was performed as follows.

The portion of the given transportation route within a fi ve-mile radius of the control room was divided into a number of segments. An accident involving the tota l loss of lading of a single container was postulated to occur at the center of each segment. The probability that such an accident could cause the concentration in the control room to exceed the IDLH level within two minutes of detection was calculated, using the data on the joint frequency of o ccurrence of stability class, wind speed and direction in FSAR Tables 2.3-126 to -132. For a chemical that cannot be detected, t he probability was calculated that the IDLH would be exceeded during 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> after the accident. (It is assumed that Waterford 3 would be notified by the St. Charles Parish Industr ial Hotline within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of any major accidental release of toxic chemicals.) An overall annual pr obability of such an event was then calculated, using d ata on the frequency of shipment of that c hemical in the particular transport mode. (EC-5000082218, R301) 2.2.3.3.6 Results

The hazardous chemical sources in the Waterford 3 vicinity, either stationary sources or transient sources treated as stationary, were analyzed using t he methods described above. None of the stationary sources were found to pose a hazard under 95% percentile meteorological conditions.

EC-5000082218, R301)All chemicals frequently shipped by truck, ship or bar ge in the Waterford 3 vicinity, were analyzed, each cargo or shipping container being regarded as a stationary source. (RG 1.78 specifies the frequencies for

each shipment mode that require consideration.).

One of the river shipments was found to pose a hazard to Waterford 3 if treated as a stationary source.

Six of the chemicals transported on the Union Pacific Railroad and one chemical transported by the Canadi an National Railway posed potential hazards if treated as stationary sources. These were t herefore analyzed by the probabilistic model described above. The results of these analyses are shown in Table 2.2-4A. (DRN 99-1089, R11;01-076; 05-149, R14;05-845, R14; EC-41671, R307)These analyses showed that the overall probability t hat toxic chemicals frequently transported in the vicinity of Waterford 3 could pose a potential hazar d to the Waterford 3 control room personnel is approximately 6.15 x 10

-6 per year. Incapacitation of the operator s will not necessarily lead to radiological releases in excess of 10CFR50.67 guidelines. The plant would have to experience a reactor trip and

multiple system failures would have to occur to produce core damage. NUREG/CR-2650 (97) suggests a value of 0.1 for the probability that incapacitation of the operators would lead to a radiological release in excess of 10CFR50.67 guidelines. With this fact or, the probability that toxic chemicals frequently transported in the vicinity of Waterford 3 could cause a radiological release in excess of 10CFR50.67 guidelines is 6.15 x 10

-7 per year. This probability may be compar ed to the guidance in Section 2.2.3 of Regulatory Guide 1.70 and Section 2.2.3 of the Standard Review Plan (NUREG-0800). As indicated there: (DRN 99-1089, R11;01-076; 05-149, R14;05-845, R14; EC-5000082218, R 301; EC-41671, R307)

WSES-FSAR-UNIT-3 2.2-54 Revision 301 (09/07)

"...the identification of design basis events resulting from the presence of hazardous materials or activities in the vicinity of the plant is acceptable if the design basis events include each postulated type of accident for which the expected rate of occurrence of potential exposures in excess of the 10CFR100 guidelines is estimated to exceed the NRC staff

objective of approximately 10

-7 per year."

Furthermore,

"...the expected rate of occurrence of potential exposures in excess of the 10 CFR Part 100 guidelines of approximately 10

-6 per year is acceptable if, when combined with reasonable qualitative arguments, the realistic probability can be shown to be lower." The model used to perform these probabilistic analyses employed a number of conservative simplifications.

1 It was assumed that the operators will be immediately incapacitated by exposures to concentrations exceeding the IDLH. In fact, the IDLH is defined as a level to which a person can

be exposed for 30 minutes without excape-impairing symptoms or permanent health effects. (DRN 01-282) 1 The calculated release rate was maximized by assuming an instantaneous, complete rupture of the storage tank and an overly rapid expansion of the spill area. (DRN 01-282) (EC-5000082218, R301) 1 The model assumes a delay of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> before Waterford 3 is alerted by the St. Charles Parish industrial hot-line or through other agencies. It is most likely that the notification would occur sooner. The worst consequences of a release usually occur under low wind speeds; therefore there can be a considerable time lapse between the occurrence of an accident and the arrival of

vapors at Waterford 3. The operators would be alerted and be able to take protective action

during this period. (EC-5000082218, R301)

Since the probability is below the 10

-6 per year criterion, the results indicate that the protective features described in the FSAR provide adequate protection for the control room operators.

2.2.3.4 Design Basis Fires in the Vicinity of the Site

See Subsection 2.2.3.2.

2.2.3.5 Collisions With The Intake Structure

Waterford 3 does not have a safety-related intake structure providing essential cooling water to the plant other than initial fill (see Subsection 10-4.5). Therefore, potential collisions with the intake structure have

not been considered as design basis events.

2.2.3.6 Liquid Spills

For the reasons given in Subsections 2.2.3.3.1 and 2.2.3.3.2 liquid spills are not considered as design

basis events for Waterford 3.
