WNP- 1 Amendment 3 i FPSR l t A. INTRODUCTION On April 6, 1977, the " Fire Protection Evaluation" for WNP-1/4 was submitted to the NRC for review. Amendments 1 and 2 to the evaluation were submitted on February 27, 1979 and June 12, 1980 respectively. On January 22, 1982, the Supply System's Board of Directors voted to terminate WNP-4. Therefore, in this amendment references to WNP-4 have been deleted. On November 19, 1980, the NRC issued Appendix R to 10CFR50, effective February 17, 1981, amending its regulations to require certain provisions for fire protection at operating nuclear power plants. This rule applies to all nuclear power plants licensed to operate prior to January 1, 1979. It was supplemented by the NRC generic letter 81-12 (2/20/81) requesting addi-tional information required by the Staff in order to complete the Appendix R review thoroughly and expeditiously. Appendix R was extended to include WNP-1 by letter from Mr. R. L. Tedesco, NRC, to Mr. R. L. Ferguson, Supply System, received January 16, 1982. This review re' quired not only a more comprehensive evaluation of safety systems, including those structures, systems and components important to safe shutdown, but also a reevaluation of the fire protection program, fire hazards analysis, and fire protection features at the plant. Therefore, the previous comparison to BTP-9.5-1, Appendix A has been updated to incorporate g'"S 10CFR50 Appendix-R requirements and to incorporate design changes since the ( ,) submittal of Amendment 2 to the " Fire Protection Evaluation" for WNP-1. The format for the Fire Protection System Review (FPSR) follows the outline of SRP 9.5-1, Rev. 3. All topics are included for ease in future comparison to SRP 9.5-1, Rev. 3. Comparison has not been made in this submittal in order to allow for appropriate analysis of all parts of SRP 9.5-1, Rev. 3. This comparison will be made in the next submittal of the FPSR when the in-depth circuit analysis is made for WNP-1. In order to conduct the aforementioned review, a multi-disciplined task force was formed. The task force encompassed A/E (United Engineers & Constructors Inc.) design personnel, operations personnel and qualified fire protection consultants. Design and operations personnel identified the s' ructures, systems and components important to safety and performed the Failure Modes and Effects Analysis (FMEA) based on the Appendix R criteria. The fire pro-tection consultant, Professional Loss Control, Inc., performed the fire hazards analysis for each fire area and compared the overall fire protection program to the appropriate regulatory positions. The resumes for the key individuals involved in the development and review of the completed FPSR are included at the end of this section. < h i J A-1 N

l l l WNP- 1 Amendment 3 FPSR Section C.S.b identifies the systems and functions important to safe O shutdown. It also describes the methodology utilized in determining equipment. This list provided input for the Fire Hazards Analysis in Section D. The methodology utilized in the Fire Hazards Analysis is described in Section C.I.b. Section C outlines the plant fire protection program and addresses plant fire protection features covered in the NRC guidelines. Each subsection is correlated to the appropriate section of both 10CFR50, Appendix R and BTP-9.5-1, Appendix-A in Section E. The Fire Protection System Review (FPSR) is a comprehensive documentation of the Fire Protection Program and Fire Hazards Analysis for WNP-1. It is a ready reference for fire protection objectives and criteria utilized in plant design and operation. It is a working document that will be updated as necessary to incorporate plant changes. The document is intended to allow continuity in implementation of the Fire Protection Program during design, construction and operation. O O A-2

3. Combustible Material which is expected to release heat Material energy when ignited, heated or otherwise exposed to abnormal conditions.

4. Combustible Loading: (1) Potential heat energy of combustible materials expressed per unit area. This is usually calculated by multiplying the total mass of materials in an area by the heat of combustion and dividing by the floor area of interest.

(2) More generally, used to. describe qualitatively the fire hazard associated 7g with an area from a total heat energy ( ) standpotnt. v (3) Used to correlate varying types, amounts and densities of combustible materials to an equivalent fire severity in terms of the ASTM E119 standard time temperature curve. (See fire severity).

5. Design Basis Fire: Maximum credible fire within the specified fire (DBF) zone or area based on the fixed and transient combustibles available.

6. Exposure Fire: A fire in a given area that involves either in-situ or transient combustibles external to any structures, systems, or components of interest located in or adjacent to .he same area. The effects of such a fire can adversely affect those structures, systems or components important to safety. Thus, a fire involving one train of safe shutdown equipment may constitute an exposure fire for the redundant train located in the same area, and a fire involving combustibles other than either redundant train may constitute an exposure fire to both redundant trains located in the same area.

Although l each aspect is addressed independently by the fire protection program, each also interacts with the others. Improvement in any one aspect will strengthen .; the overall fire protection program and may compensate for weaknesses, known or unknown, in others. , l The first part of the fire protection program objective, fire prevention, is accomplished by development and implementation of administrative controls. These controls are designed to minimize transient combustible loading where possible, to minimize the presence of ignition sources and to assure imple-mentation of the fire protection program with respect to all essential safety-related facets of plant operations, The second part of the objective is met by designing, installing, and main-taining fire detection and suppression systems to detect, contain, control l and/or extinguish postulated fires. Administrative controls on transient I combustibles act to limit the size of the postulated fire to that which was evaluated. Fire suppression systems include both automatic and manual i suppression capabilities. The third part of the objective, minimizing the consequences of the postulated fire, is demonstrated through the fire hazards analysis. The zone by zone evaluation identifies the equipment important for safe operations as well as the fire loading. Through the methodology established in a subsequent section, the design basis fire is established for each area of analysis and its con-sequences determined. The designation of fire areas provide a boundary con-dition (i.e. rated fire barriers) to limit the spread of a fire. The fire l barriers establish the outside limits for the severity of a postulated fire. Administrative controls are developed to assure that appropriate steps are h C.1-1

By utilization of the fire protection program from design through operation, the ability to minimize significant fires and to ensure the capability to shutdown the reactor and maintain it in a safe shutdown condition is achieved. In addition, radioactive releases to the environment are minimized even in the event of a significant fire. Management has and will continue to participate in the fire protection program from design through operation. The fire protection program allows management to delegate the responsibility for the engineering design and maintenance of fire protection systems to a qualified staff. In addition the qualified staff will be responsible for fire preventioit activities, training and manual fire fighting activities.

Although the Director of Safety and Security retains the ultimate responsibility, development of pro-gram policy and auditing for assurance of program implementation are delegated to the Manager of Industrial Safety and Fire Protection. Program implementation is the responsibility of the WNP-1 Plant Manager.

The Supply System has employed United Engineers & Constructors, Inc. to design and select equipment, and inspect and test the completed physical aspects of the fire protection system. The qualification of the individuals coordinating this f unction are stated in Section 1 of this report. The qualification of the Supply System Fire Protection Engineer who will assist in the inspection and test of the completed physical aspects of the system, develop the fire protection program and assist in the fire fighting training for the operating plant are provided in the FSAR (Section 9.5.1). The training and updating provisions such as fire drills , providing for main-taining the competence of the plant fire brigade including personnel responsible for maintaining and inspecting the fir' protection equipment, are also under his cognizance.

These individuals assist in the design of the system and the selection of equipment, and will assist in the inspection and test of the completed system. The Manager of Industrial Safety and Fire Protection will develop the fire protection program and assist in the fire fighting training for the operating plant personnel. C.I.b Fire Hazards Analysis Methodology

1) Introduction The primary purpose of the Fire Hazards Analysis is to provide a systematic evaluation of the fire hazards with respect to plant safety systems. The objectives of the analyses are to ensure that the interactions of the fire hazards, fire protection features and safe shutdown systems are such that under fire accident conditions, safe shutdown capability is preserved and radioactive releases to the environment are minimir.ed. In addition, the effect of inadvertent operation of the fire protection systems is considered for their impact on plant safety.

A critically important point is that most regulatory compliance items with regards to fire protection features are independent of the results of a fire hazards analysis. However such analysis is critical in evaluating post fire accident shutdown capability. The prescriptive nature of the regulations and guidance used precludes the necessity for such analysis with notable exception of the post fire safe shutdown system evaluation. Therefore, the most important criteria used in the conduct of this evaluation are those of post fire accident safe shutdown capability. The adequacy of fire protection features for shutdown systems and components including spatial separation, passive barriers and active systems was evsluated by comparison with the requirements of 10CFR50 Appendix R. Deviations from this approach are evaluated and justified as they arise in the analysis. The basic tasks performed during the Fire Hazards Analysis section of the FPSR include:

1. Identification of Fire Zones and Fire Areas.

2. Evaluation of Design Basis Fires in each area.

1. Identification of safe shutdown systems, including all necessary cabling, components and instrumentation.

7. Decision process on protection, rerouting, alternate means.

8. Evaluation of radioactive release caused by Design Basis Fire (s).

9. Evaluation of inadvertent actuation of fire protection systems on safety-related systems.

10. Determination of additional desig*. or operational features to ensure objectives.

In this manner, a systematic plant review with respect to the basic objectives of the fire protection program was accomplished. The data and analysis are summarized by fire area or zone, as shown on the example Fire Hazards Analysis sheet (shown on the following pages), t O l l O C.1-4

2) Identification of Fire Zones / Areas Fire areas exist as a fire protection feature, generally enclosed with 3-hour barriers, utilized to limit the consequences of a fire by minimizing the area exposed.

Two criteria were used in selecting the boundaries of fire zones: the logical location of local exposure fire sources and the physical boundaries located around plant subsystems. It is critically important to realize that the boundaries of fire zones do not necessarily correspond to fire barrier locations or to the location of detection or suppression system zones. Where several fire zones are located within a given fire area, the combustible loading associated with all fuel items within the three hour fire rated enclosure is used. The specification of fire zones in this manner offers the following advantages:

1. More precisa definition of the probable transient fire loads is possible.

2. Direct,. localized fire exposure can be more adequately addressed.

3. Fire areas within three hour rated fire barriers are in general too large to adequately identify safe shutdown system cables, instruments, equipment piping etc. in a meaningful manner. The use of fire zones enables this crucial task to be performed more accurately.

4. The specification of additional protection features, particularly

• passive fire barriers is clearer, enabling better analysis and easier review.

3) Evaluation of Design Basis Fire Incident (s)

Design Basis Fire incidents are assumed to be fully developed post-flashaer fires within the boundaries of a fire area. The rationale for choosing such an unrealistically conservative assumption in most plant area is based on the following:

1. In most cases, the combustible loading concept gives conservative results when evaluating passive fire barriers.

2. The practice of equating fire development with combustible loading has been used in the past and has been accepted by the NRC.

i In unique situations where the combustibles are not continuous or unusually li ght combustible loadings exist, an alternate approximation involving more detailed, complex calculations can be utilized. The availability of such calculations as a tool for evaluating design basis fires is a function of the state-of-the-art in fire dynmamics. Since the primary purpose of the combustible loading evaluation is to examine the adequacy of passive fire barriers the approximation is adequate. Detailed exposure calculations, when required, are performed utilizing more technical models. Calculations O C.1-7 l l

WNP- 1 Amendment 3 FPSR of actuation time for detection and suppression nystems will be performed, when required, using the best available physical models. All fire ares boundaries are nominally three hour fire rated assemblies. With few exceptions, the combustible loading posed by fixed and transient combustibles will not pose an exposure even approaching this limit. This factor, in conjunction with the low probability of post flashover fire states in plant fire areas indicates that the combustible loading concept is sufficiently conservative. Both fixed and transient fire loads are considered in the combustible loading calculations. The approximation of transient fire loads considers maximum loading usual to the area and conservatively accounts for uncertain operating conditions. Fixed fire loading, such as cabling and lubricants, was calculated based on the following assumptions:

1. The combustible loading of a mass of cabling, including insulation and jacket materials, is taken to be 10,400 Btu /lb even though all cabling is IEEE 383 qualified.

2. Cabling enclosed in conduit contributes no fuel to a postulated fire in that area.

3. Cable trays are taken as 40% filled as an average for combustible loading calculations.

4. Effective heating values of combustibles are assumed as follows:

Mineral Oil 150,000 Btu / gal Turbine Lubricating Oil 150,000 Btu / gal G rea se 18,000 Btu /lb Cellulosic Materials 8,000 Btu /lb Polymeric Materials 13,000 Btu /lb Charcoal 13,000 Btu /lb Cable Jacket / Insulation Materials 10,400 Btu /lb Resins 15,000 Btu /lb Fuel Oil (No. 2) 150,000 Btu / gal

5. Combustible loadings due to rotor winding insulation is not considered.

O C.1-8

WNP- 1 Amendment 3 FPSR

6. A fire cf maximum credible intensity was assumed in order to evaluate the adequacy of passive fire barriers. This assumption overestimates the room conditions during a fire; hence, barriers adequate for such exposures are adeqaute for the more likely, less severe, conditions,

7. Demineralizer resins located inside of equipment are assumed to con- i tribute no fuel loading to an area. However, open storage of resins near the demineralizing equipment is assumed as a transient combustible.

8. Filters, other than charcoal, in HVAC units are not considered to contribute to the combustible loading. ,

9. Pipe insulation is non-combustible and therefore will not contribute to the combustible loading.

4) Effect of Fire Exposure on Safe Shutdown Capability In general, the following assumptions apply to the evaluation of potential damage to safe shutdown systems:

1. Regardless of the particular fire exposure, unprotected cable insulation was assumed to result in loss of cable function. Adequate protection was assumed, in general, to consist of a combination of passive fire barriers and active fire protection. The passive barrier assumed was

' to be a one-hour rated cable protection scheme. Where specifically justified on the basis of limited fire exposure and/or rapidly actur. ting

   '~'                     suppression systems, the one hour barrier scheme may be eliminated or downgraded.

2. In evaluating the protection for safe shutdown equipment, failure of the automatic fire suppression system was not assumed. However, in all cases, the availability of backup or secondary means of fire suppression was demonstrated.

3. Damage to unprotected instruments, valves, piping, pumps, etc. in zones containing automatic suppression systems was evaluated on an individual basis.

4. Liquid filled piping was assumed to retain integrity for a sufficient time to allow initiation of effective manual and/or automatic fire suppression operations.

5. Valves on liquid filled piping were assumed to maintain their integrity for sufficient time to allow initiation of effective manual and/or automatic fire suppression operations.

6. Motors and valve operators were assumed to fait prior to actuation of suppression systems if not protected by a passive barrier.

  \

C.1-9

WidP- 1 Amendment 3 FPSR

7. Liquid filled pumps were assumed to maintain mechanical integrity for a sufficient time to allow initiation of effective manual and/or auto-matic suppression operations.

8. All power, control and signal functions provided by exposed cables or cables in conduit were assumed to fail prior to automatic suppression system operation unless provided with passive fire barrier protection.

In a f ew cases, where limited fire exposures were expected to be spatially separated from cable / conduit systems, the operation of the suppression system prior to cable function damage may be demonstrated on an individual basis.

9. No credit was taken for brigade response as a primary suppression means when safe shutdown systems were exposed. The primary means of evaluating the protection of safe shutdown capability was to utilize the requirements of 10CFR50 Appendix R, Section III, G.2.a and c. In general, a combination of fire detection, fire suppression and passive fire barriers was utilized (Section III.G.2.c).

If the protection scheme for the safe shutdown equipment was in accordance with Section III.G.2.a, 10CFR50 Appendix R, its acceptability to perform that protection function was assured unless extreme fire exposure conditions were anticipated.

5) Evaluation of Fire Damage to Safety Related Systems Safety-related system components are identified by fire zone and/or area.

The effects on such components, when exposed to the Design Basis Fire within the area, were analyzed to verify that a fire occuring within one system would not result in damage to the redundant system. An exposure fire result-ing in damage to redundant systems (not safe shutdown systems) was considered to be acceptable in accordance with the requirements of Appendix R to 10CFR50. Fires are not postulated as occurring simultaneously with design basis accidents or events.

6) Evaluation of Radioactive Release Potential Caused By Design Basis Fires tie purpose of this evaluation was to ensure that no design basis fire incident would result in excessive radioactive atmospheric or liquid effluent release.

This is shown in the following ways:

1. Post fire saf e shutdown capabili ty is preserved.

2. No fire inuuced post-accident mitigation function is impaired by a single fire originating in a single train of required safety-related equipcment.

3. Liquid effluents caused by fire protection system actuation in con-taminated areas are controlled by adequate containment and drainage.

O C.1-10 I

WNP- 1 Amendment 3 FPSR O () 4. Airborne contamination resulting from a fire exposure is adequately controlled through ventilation and monitoring. The post fire safe shutdown capability is the major concern of the fire hazards analysis. The assurance of such a capability eliminates this potential source. The release of radioactive liquid effluents was analyzed by considering the adequacy of the plant drainage system. Fire induced f ailures of secondary containment resulting in a potential release of radioactive liquid effluent were evaluated. These effluents were assumed to be fire induced, therefore, the primary source was an automatic or manual fire suppression system. The release of airborne contamination resulting directly from a fire incident, i.e. a " radioactive" smoke plume, was evaluated by considering the plant ventilation and atmospheric monitoring system. Airborne contamination re-sulting from other causes was examined by the evaluation in items 1 and 2 listed above.

7) Evaluation of Inadvertent Fire Suppression System Operation The potential effects of the accidental operation of a fixed fire suppression system were evaluated under the following assumptions:

1. For closed head water suppression systems, only single nozzle discharge was assumed.

\s- 2. For gaseous suppression systems, all discharge points on a given single actuation zone were considered.

3. Damage caused by accidental discharge of a single suppression system nozzle was assumed to be limited to inducing electrical control, signal or power failures. Especially critical items include; switchgear, motor control centers, instrument panels, control panels , non-drip proof or non-waterproof electrical motors.

4. Water discharge on insulated, undamaged cables was assumed to cause no damage to such cables.

5. Where floor drainage was evaluated as adequate, the effects of water damage caused by a liquid level rise in the zone were not considered, since equipment is installed on pads or pedestals.

C.1.c Fire Suppression System Design Basis The fire hose standpipe system design has a header through the General Services Building that is an extension of the yard main system and connects with the yard main system at two (2) remote points. The header is controlled by post indicator and building interior isolation valves at each end so that a single failure of the system will not create a lack of water supply to the building. Automatic sprinkler systems have an independent connection to the yard main

,m \

A \s.- Y C.1-Il

WNP- 1 Amendment 3 FPSR system. Each system takeoff is through a system valve, either OS&Y or other approved shutoff valves, and a water flow alana. Therefore, a fire suppression system line break will not disable both the hose standpipe system and automatic suppression system at the same time. The hose standpipe system in the Containment and the GSB are designed to be functional after the safe shutdown earthquake. As described in Section C.6.c, an alternate water supply, designed to Seismic Category I requirements , is provided for the hose standpipe systems. C.I.d Alternative or Dedicated Shutdown The equipment / system used to provide Safe Shutdown (SSD) capability was selected from plant systems that provide reactivity control, reactor coolant system inventory control and reactor decay heat reuoval. Any system that interfaces with the SSD equipment or is needed to support the operation of Safe Shutdown equipment was given SSD equipment / system status. The SSD equipment / system have either redundant trains that provide the same function or redundant components that provide the same function. The equip-ment / system selected is provided with dual power sources, off-site power, if available, and on-site power if off-site power is not available. The SSD equipment / system selected, in general, have redundant / alternate controls. They can be controlled from the control room, from one of the two hot shut-down panel areas, or locally. For a further discussion of the SSD equipment / systems see Section C.S.b and C.5.c. C.I.e Imylementation of Fire Protection Program Fire Protection Program implementation is the responsibility of the Plant Manager. During construction, United Engineers & Constructors, Inc. (UE6C) as Architect-Engineer, and Bechtel Power Corporation, as Construction Manager, provided the design and installation of fire protection systems. They also assist in the selection, inspection, and testing of equipment for the completed fire protection systems. The Plant Manager will be responsible for the im pleme n t a t ion , through ad-ministrative procedures, of the plant fire protection program requirements. This will include maintenance and surveillance of fire protection systems, testing of fire protection equipment, fire safety inspections, fire protection training, fire fighting procedures, fire drills, etc. O C.1-12

WNP- 1 Amendment 3 FPSR C.2 Administrative Controls C.2.a Testing A successful fire protection program requires testing of the fire protection equipment. Testing of fire suppression and fire detection systems will be completed in accordance with the appropriate NFPA standards, NRC guidelines and the plant technical specifications. Testing will be accomplished under the supervision of the Shift Supervisors and Maintenance Supervisors in accordance with the surveillance testing program procedures. Leak testing, smoke detector testing and similar procedures such as air flow determination will be done by means other than open flames or combustion generated smoke. Persons performing the tests of fire suppression and fire detection systems will be qualified by appropriate experience and/or training in conducting these tests. C.2.b Surveillance The Plant Manager is responsible for the development of administrative pro-

~

cedures necessary to meet the surveillance requirements outlined in the Plant

  . Technical Specifications.

1 Surveillance procedures will be established to ensure that fire barriers are in place and that fire suppression and fire detection systems are operable. Fire barrier surveillance will include fire doors , fire dampers, cable pene-tration seals, and other mechanical penetration seals. Surveillance procedures will include provisions for correcting deficiencies found as well as maintaining a record of the surveillance and the correction of any deficiencies. C.2.c Control of Combustibles i T'he use of plastic materials is minimized where possible. In particular, halogenated plastics such as PVC and neoprene are used only when substitute non-combustible materials are not available. Where neoprene is used as cable jacket material, it will be qualified to IEEE-383-1974 flame test requirements. Bulk storage of flammable liquids will, as a minimum, comply with the require-ments of NEFPA 30, "Flanunable and Combustible Liquids Code" in the design and venting of tanks. All bulk storage tanks containing flammable and combustible liquids are protected by thermal detection and automatic deluge sprinkler systems, if they are located in the buildings or within 50 feet of a building  ! except for the turbine lube oil storage tanks which are located about 50 feet I from the Turbine Cenerator Building. These tanks are situated above an open b G , 1 C.2-1 l

WNP- 1 Amendment 3 FPSR pit designed to contain the oil stored in the tanks. Protection will be afforded by fire hydrants and hose houses in the area of the tar.k. These tanks are used primarily during shutdown while performing maintenance on the turbine / generator and contain clean and dirty lube oils. Ef f ective administrative measures will be implemented to prohibit bulk storage of combustible materials inside safety related buildings or adjacent to safety related systems during operation or maintenance periods. Guidhnce provided in Regulatory Guide 1.39 will be utilized in the development or these measures. Use of combustible materials such as charcoal filters, dry ion exchange resins, wood laydown supports, or other combustible supplies, will be controlled in all safety-related areas. Other use of wood in buildings containing safety-related systems or equipment will not be permitted, except when suitable non-combustible substitutes are not available. If wood is used for such purposes, only identifiable fire retardant treated wood will be permitted. Such materials and supplies will be allowed in safety-related areas only du, ring periods of use and storage of such materials will not be permitted. , /', All safety-related systems are isolated or separated from combustible material wherever feasible. Where isolation is not feasible, appropriate fire pro-tection is provided, based on the fire hazards analysis, to ensure that a fire does not defeat the safety-related system function. C.2.d Control of Ignition Sources Administratise controls will be established to protect safety related areas from work involving ignition sources, such as welding, cutting, grinding, or use of open flame work. Controls will provide for a permit system to control welding, cutting, grind-ing and open flame work. Permit issuance will be handled by qualified personnel at a responsible point of control and will require appropriate measures before, during and after the work is performed. Administrative controls vill be established to prohibit the use of open flame or combustion smoke for leak or fire detection system testing. Smoking in safety-related areas will be controlled by establishing designated smoking areas and posting of "No Smoking" signs. O C.2-2

WNP- 1 Amendment 3 FPSR t C.3 Fire Brigade C.3.a Personnel A minimum fire brigade team complement of five persons will be maintained on all shifts. Fire brigade composition for each shift will be as follows: The Fire Brigade shall consist of the following personnel: A) Shift Support Supervisor - Brigade Leader i B) Equipment Operators (2) C) Health Physics / Chemistry Technican (1) I D) Maintenance Support Personnel (1) The Fire Brigade Leader is dedicated to stay with the brigade during a fire 1 emergency. 1 The Industrial Safety and Fire Protection Specialist assigned to the plant will fill the position of Fire Brigade Chief.

Applicable fire protection industry standards and other pertinent industry , reference materials are used in developing the fire brigade training program. ( l l C.3-1

WNP- 1 Amendment 3 FPSR Additionally, courses in fire protection and fire suppression sponsored by f the fire protection industry will he utilized. The Fire Brigade personnel will be trained and retrained in responding to and fighting fires in accordance with the Fire Brigade Training Program. This training program is prepared and conducted by qualified personnel from the Industrial Safety and Fire Protection Department (IS&FP). Fire arigade leaders may also conduct this training as prepared by IS&FP. Initial fire brigade training will include:

1 4 WNP- 1 Amendment 3 FPSR C.5 General Plant Design C.S.a Building Design The General Services Building consists of steel supported reinforced concrete floors with reinforced concrete bearing walls. Where steel structural members are a part of a three hour rated fire barrier, they are protected with a coating tested to provide a three hour fire resistance for the steel. Where the failure of steel structural members within a fire area could jeopardize the boundary of the barrier, these steel members are also protected. Metal deck roof construction is non-combustible and canplies with the require-ments of Class I construction of Factory Mutual requirements. All Category I buildings in the plant are fully protected from lightning by a lightning protection system consisting of lightning masts tied to an adequate grounding system utilizing NFPA 78, Lightning Protection Code, as guidance. There are no combustible oil-filled outdoor transformers located within 50 feet of a building containing safety-related systems. All transformers are dry types in the areas of concern, and no other oil immersed apparatus is used in these areas. Doorways are provided with unlabeled UL-63 equivalent imbedded frames and approved fire doors providing three hour rated fire resistance. Where remov-

       ') able transoms are used for equipment accessibility, manufacturer certification C./

s is provided to assure construction of doors and transoms is equivalent to that of doors listed for three hour rated fire resistance. Elevator doors have a lh hour rating. Fire exits will be clearly marked; exit routes will be clearly marked and established by pre-fire plan. Periodic drills by operating and fire brigade personnel will bc conducted to establish familiarity with these routes and procedures.

!         All stairwells and elevator shafts in the General Services Building are en-closed in concrete towers built to three hour fire resistive construction with three hour fire rated doors on the stairwells and 1 1/2 hour doors on the elevators.

All fire doors in the stairwells are of the self closing type and are normally closed. The stairwells in the Containment and the Isolation Buildings are not enclosed by fire rated barriers, th ere f ore , escape and access route procedures described above will be followed. Containment hatches do not have a fire rating, although substantial steel construction and multipoint latching are at least equal to a three hour rated g door.

  .Q

. C.5-1

WNP- 1 Amendment 3 FPSR All penetration seals in three hour rated fire barriers will be rated at three hours. f All dampers installed at three hour rated fire barrier walls will have a rating equivalent to the wall. Where stainless steel dampers have been utilized for contamination control purposes, two 1 1/2 hour rated dampers have been utilized in series to protect ventilation penetrations. Suspended ceilings and their supports are non-combustible construction. Concealed spaces may house telephone cabling, control and low power wiring with combustible insulation / jacket. This wiring is in conduit. Concealed spaces may also contain lighting wiring which is in conduit or is aluminum sheath cable. Lighting wiring in the Main Control and Auxiliary Equipment Room is run in conduit. This wiring does not contribut'e combustibles as discussed in Fire llazards Analysis section of the FPSR. The computer sub-floor has cabling which is not in conduit. Ilowever, this area is protected by a total flooding Italon system. Interior finishes in safety related areas have a flame spread, fuel contri-bution and smoke development rating of 25 or less with the exception of the following: plaster, gypsum wallboard, wallpaper, oil or water base painted surfaces, ceramic tile or panels, vinyl tile, vinyl-asbestos tile, linoleum, or asphalt tile on concrete. Interior finishes have a flame spread rate and fuel contribution and smoke of development 25 or less except paint which has a smoke development of 125. The plant design locates floor drains through the plant's buildings where required. Special consideration is given in those areas where fixed water spray systems and/or hose streams would put excessive quantities of water on the floor. The water from the floor drains in non-radioactive areas is collected in several floor sumps where it is continually checked for radioactivity prior to being pumped to the Radwaste Treatment Area for processing. Floor drains in potentially radioactive areas are drained directly into the Radwaste Treatment A rea . Areas that may have combustible fluids (i.e. Diesel Generator Areas, Diesel Fuel Storage Areas) have floor drain systems and/or floor sumps for accumulation of fire water and combustible liquids. These floor drains are all trapped to prevent burning liquid from backing up through another floor drain and the sumps have their inlets under the normal water line. Where flooding may be a problem, all mechanical plant equipment is mounted on pedestals, therefore, water accumulation on the floor will not be detrimental to equipment operation. Electrical equipment is generally mounted on pads; however, when not, water accumulation on the floor has been determined not to be detrimental to the equipment. O C.5-2

WNP- 1 Amendment 3 FPSR O Floor drains and/or curbs are provided to prevent damage to safety related equipment in adjacent areas from automatic and/or manual fire suppression , system operations. C.S.h Safe Shutdown Systems

1) Introduction In order that the objective of the Fire llazards Analysis could be met, it was necessary to identify those systems normally required or which could be used to shutdown the plant. The criteria used to select those systems or portions of the systems for the safe shutdown list involved four categories.

These four categories are:

1. Reactivity Control

2. Removal of Decay lleat

3. Maintaining Reactor Coolant Inventory and Pressure Control

4. Support Services for Categories 1 thru 3 Reactivity control is achieved by insertion of the control rods and by in-jection of boron into the Reactor Coolant System (RCS). Control rod insertion is accomplished by interrupting the electrical power to the control rod drive

[sT mechanisms. This allows rapid insertion of the control rods into the core U region. Boron injection is accomplished by using the Make-up System (MUS), a high pressure injection system, as the injection path for borated water. Borated water is obtained from the borated water storage tank (BWST) or by the injection of concentrated boric acid from the storage tanks directly into the suction of the MUS pumps. Decay heat generated at the reactor core is removed by the Reactor Coolant System (RCS). 1: eat is removed from the RCS during hot shutdown conditions by the secondary side of the steam generators or during cold shutdown conditions by the Decay Heat Removal System (DHR). Reactor coolant inventory is maintained by assuring the MUS a continuous supply of water. This water source is the BWST. The RCS inventory can be maintained by coordinating pressurizer level indication with the operation of the MUS. Primary pressure control can be maintained by use of the pressurizer heaters ou an "as required basis". A second method of pressure control is use of the pressurizer spray valve. Support systems required for the systems in the first three categories fall into general classification such as: Electrical Power Distribution, Equipment Cooling, and Ventilation needed to maintain environmental g v

   ! conditions.

C.5-3

WNP- 1 Amendment 3 FPSR Another group of support sjstems which do not directly support a system but is of equal importance are lighting and communications systems. lf Certain systems like Emergency Load Sequencer (ELS) and Emergency Power Sequencing System (EPSS) are electrical systems that sequence loading of the Emergency Diesel Generators (EDG) and provide automatic line-up of systems in response to a LOOP or ESFAS (Engineered Safety Feature Actuation System) condition. Since ESFAS is in response to a Design Basis Event (DBE) and Appendix R does not consider a DBE concurrent with a fire, that portion of EPSS which pertains to ESFAS was not considered for Appendix R treatment. Appendix R considers two electrical power conditions; condition one is off-site power available and condition two is loss of off-site power (LOOP). With off-site power available, the ELS and EPSS systems will not be needed to perform their intended functions. During a LOOP, these two systems will be used at the beginning of Appendix R fire sequence of events and since both systems have a durs. ion of use measured in minutes, they will subsequently be isolated electrically from the SSD circuits in order to prevent spurious operation during a fire.

2) Methodology Systems required for Fire Induced Safe Shutdown (FISS) were selected from the WNP-1 Operating System List based on Babcock & Wilcox Standard Technical Specifications (NUREG 103), the FSAR and UE&C System Design Descriptions.

10 CFR 50 Appendix R criteria were applied to the preliminary list to further reduce the number of systems needing in-depth analysis. The Appendix R criteria used to reduce the preliminary list were the following:

1. Appendix R postulates that a loss of off-site power can happen con-currently with a fire.

2. Single failure was not assumed to occur except to equipment that was damaged by the fire.

3. Design basis events do not occur simultaneously with the fire.

The resulting list of systems was used by the task force for in-depth analysis. Each system, that was selected for in-depth analysis, was analyzed for applicable flow paths. Once a flow path was established, boundaries and other system interfaces were established. (See Exhibit 2 P&ID). Boundaries were established based on the functional use of the system com ponen t s , on the availability of normally closed manually operated valves, or on valves that will close upon receipt of a LOOP signal.

l WNP- 1 Amendment 3 FPSR If an individual component is shared with another system, i e. a tank, then . its physical boundary is considered to extend into that system, and the boundary guidelines will be extended to the other system. i a Choosing the system boundary using the above guidelines assures that fires

                 - will not cause a loss of system integrity; thus, the system's function will i                  not be lost due to a breach of the system's boundary.

Exhibit 3 (Tab sheet) shows how each system was analyzed on a component by I component basis. Those components not required are listed and a justification is given for why they are not needed. Exhibit 1 (Anal. Summary) is a report prepared for each syatem analyzed. This report lists the reasoning, the minimum equipment, and any pertinent comments that were made during the analysis. A complete set of reports is available for review as required. Table C.1 lists systems by name, the category they f all under, and the plant condition for which they will be used.

WNP- 1 Amendment 3 FPSR CATEGORY l REACTIVITY CONTROL Reactor Protection and Control Rod Drive The Reactor Protection System (RPS) performs the sole function of initiating a trip of all reactor control rods when plant conditions require such action. The RPS actuates the trip breakers used to interrupt power to the control rod drives. The portions of the RPS & CRD systeers that were given FISS analysis is the four trip breakers and the manual trip pushbuttons. The portion of the Control Rod Drive System (CRDS) analyzed is the power supply for the CRD mechanism holding current. Chemical Addition and Boron Recovery System The Chemical Addition and Boron Recovery (BRS) System is normally used to provide a chemical shim for reactivity control and to recover and recycle unused Boron from the RCS. A secondary use of the BRS is to provide a source of concentrated boric acid for use in the RCS. This provides an alternate method of shutting down the reactor (reactivity control). This is accomplished by pumping concentrated boric acid from storage tanks through filters (to remove any boric acid crystals) and injecting it into the Make-up pump suction for injection into the RCS via the high pressure injection flow path. The capability also exists for using the concentrated boric acid with DilR to maintain the cM d-shutdown reactivity margin. O O C.5-6

WNP- 1 Amendment 3 FPSR CATEGORY 2 REMOVAL OF DECAY llEAT Reactor Coolant System

The reactor is a B&W 3800 MWt two loop pressurized water reactor. The RCS consists of two (2) Once Through Steam Generators, four (4) reactor coolant pumps, reactor vessel and pressurizer, and associated piping valves, l controls and instrumentation. The RCS is used to remove and transfer I

reactor core heat to the secondary side of the steam generators or to the Decay Heat Removal System. l 1 provide assurance that the RCS is capable of performing its function, the j following guidelines were used in the Fire Induced Safe Shutdown analysis: A. The pnysical integrity of the RCS is maintained l B. Circulation is established C. Pressurizer level is maintained i D. Pressurizer pressure is controlled Circulation is established when off-site power is available by use of one or more reactor coolant pumps, and when off-site power is not available by use of natural circulation. Natural circulation is enhanced by control of the

       '~*      steam generator secondary side water level and the auxiliary feedwater flow rate.

Pressurizer level is maintained by controlling make-up flow into the RCS. Pressure is controlled by use of the pressurized Group #8 and #9 heaters, the Power Operated Relief Valves (PORV), code safety valves, and pressurizer spray. Main Steam System The Main Steam System (MSS) is the means of. removing heat from the Reactor Coolant Sytem (RCS) during startup, operation and normal shutdown of the reactor. For Fire Induced Safe Shutdown conditions with of f-site power available, the MSS is considered to consist of code safety valves, modulating atmospheric dump valves (MAD), main steam isolation valves, atmospheric dump valves, modulating turbine by pass valves, and the high pressure turbine stop valves. These valves and associated piping, controls and instrumentation comprise the primary means of removing RCS heat and placing the reactor in a l hot standby condition. The minimum components necessary for heat removal are the MAD valves. Thus, the Appendix R analysis concentrated on the minimum equipment needed. O s ,

WNP- 1 Amendment 3 FPSR Main Feedwater System The Main Feedwater System (FWS) is the normal source of water for the steam generators. The system consists of 2 main feedwater pumps, 2 stages of pre-heaters and the associated valves and piping. The FWS system requires off-site power to run the condensate system (CND) which supplies water to the FWS. During a LOOP (Loss of Off-Site Power) the CND system is not functional. The Steam Generator level indication belongs to the FWS. The level indication instrument loop will furnish level signals to the auxiliary feedwater steam generator level and feed rate control circuits. Auxiliary Feedwater System The Auxiliary Feedwater System (FWA) is the backup source of feedwater for tha steam generators. The system consists of two motor driven pumps, one steam driven pump and associated piping valves, controls and instrumentation designed to assure that sufficient water is available to the steam generators for removal of decay heat from the RCS. Each motor driven pump is powered from a separate emergency power bus. Each motor driven pump is normally lined up to a particular steam generator, while the steam driven pump is dedicated to both steam generators. Each motor driven pump can supply its alternate steam generators by operator a tion. There are two sets of logic circuits which pertain to FWA. The first set involves the Engineered Safety Feature Actuation System (ESFAS) and this logic selects only the good steam generators to feed. The second set decides what the steam generator's level and feed rate should be depending on Reac tor Coolant Pump status , temperature and pressure conditions in the RCS. Decay Heat Removal The Decay Heat Removal (DHR) system is used to remove decay heat from the RCS when the RCS temperature is below 305 F. The system consists of two motor driven pumps, two heat exchangers, and associated piping, valves, con-trols and instrumentation deeigned to assure sufficient heat removal capacity exists to put the reactor in a cold shutdown condition. The DHR system is arranged into two independent trains. Each DHR train is supplied power from two sources. One source is normal power when off-site power is available, and the second source is emergency power. Emergency power is supplied from the emergency diesel generators, noth DilR trains take a suction on the reactor coolant system loop 1 A hot leg. The trains then separate into the two individual trains. The two DilR trains then return cooled water to the RCS via the two core flooding tank discharge lines. The two trains are redundant with either train capcble of 100% cooling. C.5-8

l 1 WHP- 1 Amendment 3 i FPSR s, ) Nuclear Service Water System 1 The Nuclear Service Water (NSW) System is used to cool plant equipment during normal, abnormal and emergency conditions. Some of the systems and ! cooled components are Emergency Diesel Jacket Water System, Nuclear Instrument Air Compressors, Make-up Pumps, Component Cooling heat exchangers i and the Shutdown Cooling Water heat exchangers. The NSW System consists of piping, valves, controls and instrumentation designed to assure that sufficient water is available to remove the heat input from its serviced components. The NSW System has two independent sources of water. The normal source of water is the Balance of Plant Service Water System and the emergency source is the Emergency Shutdown Service Water System. The NSW is arranged in a two train configuration. NSW Train "A" serves associated Train "A" components while NSW Train "B" serves associated Train "B" components . Shutdown Cooling Water is a sub-system of the NSW. It is used to cool the Decay lleat Removal pumps and heat exchangers and the Containment Spray pumps and heat exchangers. The shutdown cooling water system is two independent and redundant closed loop cooling systems. Each loop consists of heat exchangers, pump, expansion tank, piping, valves, controls and instrumentation to perform its design function. Each shutdown cooling water train is supplied power from a normal and emergency source. The NSW system is automatically lined up for operation during a LOOP. In l this configuration, ESW is supplying water to the NSW system. NSW flow to j the cooled components is augmented or reduced according to the components t use during a LOOP. It is the LOOP configuration that is analyzed for FISS conditions. Emergency Shutdown Service Water System The Emergency Shutdown Service Water (ESW) System is the ultimate heat sink. The ESW system supplies water to the Nuclear Service Water (NSW) system and in turn cools the return water from the NSW System. The ESW system is designed to perf orm its function as the ultimate heat sink when the plant is i experiencing a Loss-Of-Of f-Site Power condition or a design basis event. The ESW system consists of a spray pond, pumps, piping, valves,. control and instrumentation designed to assure sufficient water is available to the NSW system to remove its heat load. Except for the spray pond itself, the'ESW system is arranged in a two train configuration. ESW Train "A" serves NSW Train "A" and ESW Train "B" serves NSW Train "B". ESW Train "A" is independent of and redundant to ESW Train "B". v) C.5-9 '

The ESW system is supplied power from two sources. One so'urce is normal ' power when off-site power is available, and the second source is emergency power. Emergency power is supplied from the emergency diesel generators. The ESW system automatically starts and lines up for spray operation during a LOOP condition. It is the LOOP mode of operation that is analyzed for FISS conditions. O O C.5-10 ) 1

Make-up and Purification System The Make-up and Purification (MUS) System provides for control of the RCS inventory, and control of the boron concentration in the RCS. The MUS also , supplies the seal water to the RC pumps and make-up water for the Core Flooding System (CFS). The MUS is part of Emergency Core Cooling during LOCA conditions, but that mode of operation is not considered under the guidelines for Appendix R review. The MUS system, for injection of water into the RCS, is configured in a two train, three pump line-up. Two of the three pumps are dedicated to Train "A" and Train "B" exclusively. The third pump is mechanically connected to both trains but requires local operator actions to valve it to a particular train. The pump also requires operator action to provide electrical power to it. The "A" and "B" train pumps are provided emergency power from the emergency diesel generators if off-site power is lost. The purification, letdown and deboration portion of the MUS is not required for Fire Induced Safe Shutdown of the reactor and can be isolated by remote operated isolation valves. This isolation is not an automatic function and requires operator action, f- The RCS Pump Seal injection and the borating function of the MUS is retained ,- (s. for FISS. The Borated Water Storage Tank is considered the only reliable source of water for the MUS. The Make-up Pump Suction is shif ted to the BWST by operator action of remote operated valves. 4 n 4 I ( l 1 s__) C.5-il

l WNP- 1 Amendment 3 FPSR C.S.b DECAY HEAT REMOVAL SYSTEM (DHR) EXHIBIT #1 ANALYSIS BASE: The DHR System is used to cool down the Reactor Coolant System (RCS) from a hot shutdown condition and to maintain the RCS in a cold shutdown condition. ANALYZED MODE: The analysis of the DHR System was based on the assumption that it is placed into operation by the reactor operator verses automatic initiation e.g. ESFAS caused. MINIMUM REQUIREMENTS: One pump, one heat exchanger and associated piping, valves, indication and control signals are available. MINIMUM PARAMETERS DHR-FT-2A, FT-2B and their associated OR CONTROL: instrumentation loops are needed. DHR-TE-4A, TE-4B and their associated instrument loops are needed. All DHR remotu operated valve controls, interlocks and indication are needed except DHR-V63-A and V64-B. DHR-PMP-1A and PMP-2B controls, indications and interlocks are needed. CONTENTS: DHR loop flow indication was selected because it would indicate the pump was running and a proper valve line-up exists. DHR Heat Exchanger Outlet Temperature was selected because it would indicate that heat was being removed from the RCS when monitored over a period of time. BWST, valves VI-A, V2-B, V63-A, V-64B and portions of the DHR that pertain to refueling operations are commented on as follows: The BWST is used as the source of makeup water to maintain the water inventory of the DHR System, hence RCS System. Valves VI-A and V2-B were analyzed for their e f fec t on DHR System Fluid Boundary. Valves V63-A and V64-B were analyzed as system boundaries because a failure of these valves C.5-14

However, it was decided that i the inadvertent opening of these valves would not constitute a problem since the flow path from these two valves is to the MUS Pump Suctions and thus back to the RCS, j The portions of the DHR System that are involved in

refueling operations were analyzed for their ef fect j- on the System Fluid Boundary.

WNP- 1 Amendment 3 FPSR 7 C.S.c Fa ilure Modes and Ef fec t.. Analysis Methodology The Failure Modes and Ef fects Analysis (FMEA) involved all safe shutdown systems or equipment defined in Section C.S.b. The safe shutdown equipment was located by using physical location drawings. The physical location was then used to find the individual components fire zone. A complete listing of coiaponents by fire zone was then compiled for all safe shutdown equipment. The compiled safe shutdown equipment fire zone listing was used as the basis for performing the FMEA. The FMEA Task Force Group assembled composite packages of equipment components corresponding to each area of analysis (Listed in Section 5 of FHA). The packages consist of system P&ID's with their respective zone equipment highlighted. The packages were assembled this way so the safe shutdown equipment could be FMEA'd on an area of analysis basis per the Appendix R criteria. The results of the analysis identified couponents/ equipment whose loss would impair safe shutdown of the reactor. These identified components / equipment were tabulated by area of analysis and the tabulation was submitted to the fire protection specialists as needing additional fire protection review for Appendix R requirements. The specialists would then determine the added protection needed for the equipment or provide justification. This result is shown in Section 10 of the Fire Hazard Analysis (FHA). O () C.S.d Control of Combustible The plant design calls for bulk compressed gas storage (hydrogen, carbon dioxide, oxygen, chlorine and nitrogen) to be well detached from major plant structures. The containers are oriented to minimize damage to any safety related equipment or structure in the event of a container failure. Fire protection will consist of use of nearby fire hydrants and hose houses. C.5.e Electrical Cable Construction Cable Trays and Cable Penetrations All electrical cabling, except lighting cable and a limited amount of communications cable in the plant, passes IEEE-383-1974 flame tests. All cables installed in open raceway systems on WNP-1 are qualified per IEEE-383-1974. All sa fety related cables conform to the provisions of Regulatory Guide 1.75. ' l All cable, conduit and cable tray penetration seals of fire barriers l l (11orizontal and Vertical) have been tested as providing the three hour rating of the fire barrier. The design of the fire barrier penetration I seals shall meet, as a minimum, the requirements of ASTM E-119, Fire Test of

,   Building Construction and Materials, including the hose stream test.

WNP- 1 Amendment 3 FPSR C.5.f Ventilation Most ventilating systems consist of a recirculating air system with capability for fresh air intake and exhaust air. This capability can be utilized for purging an area of smoke and heat. However, since the General Services Build-ing is a multi-story building, the ventilation ductwork must pass through several floors and/or area walls. The re fo re , there may be several fire dampers in the duct system that will close in the event of a fire in its specific a rea . This would then entail the manual resetting of the fire dampers prior to purging the area. The plant design incorporates ventilation systems for all cable tunnels and spreading rooms. These ventilation systems all have exhaust fea tures in them and can be utilized as such. However, in the event of a fire, fire dampers in the system may close and smoke detectors in the system ductwork would de-energize the ventilation system. These dampers would have to be manually reset and the ventilation system manually restarted prior to smoke evacuation of an area. In addition, the air supply to some areas consists of the exhaust from other areas. For example, the cable spread room is supplied through unducted penetrations from the switchgear rooms below. Fire dampers in these penetrations are operated by ionization detectors in the switchgear areas to reduce smoke spread into the cable spread area. Smoke actuated fire dampers are also provided to prevent smoke spread from the computer room, peripheral rooms and training room to the control room through the recirculating HVAC system. The plant ventilation system's designs do not specifically provide special smoke or corrosive gas exhaust systems. All exhausting will be done through the ventilation systems where possible or by use of portable equipment. The same design criteria are used in the Containment func t ions that assure public safety and in the habitability systems for the Control Room. Radioactivity carried by the products of combustion will be monitored by portable monitoring equipment carried by the fire brigade and evaluated prior to discharge. The discharge will be done through the ventilation system for the areas and will be monitored at the building exhaust port prior to discharge to the atmosphere. Since the ventilation system shuts down and fire dampers in the system close in the event of a fire, all products of combustion are maintained in the fire area until purging is initiated manually. Inadvertent operation of the exhaust portion of the ventilation system is minimized, since all fire dampers must be manually reset prior to system reactivation and the evacuation of the area. The Atmoshperic Cleanup Air Filtration units utilized in the normally operating ventilating systems of the following Category I areas of WNP-1 are provided with a bypass ventilation system that allows air from the redundant operating system to pass air over the charcoal filter of the standby unit. This flow of air is suf ficient to maintain the charcoal filters, if they are " loaded" with radioactivity, at a temperature below the auto-ignition temperature of  ; 1 C.5-17

WNP- 1 Amendment 3 FPSR i 4 radioactive charcoal. Normally clean charcoal will not auto-ignite. The use of this bypass ventilation system is in compliance with Regulatory Guide 1.52, Rev. 1, dated July 1976, paragraph "K" of Section 3, " Component Design Criteria and Qualification Testing." IIVAC SYSTEMS WITH CHARCOAL FILTERS Control & Auxiliary Equipment Room (HCL) Fuel Storage Area (HSF) Safeguards Area (llSG) Piping & Electrical Areas (HPT) Component Cooling Auxiliary Area (HCA) Containment Purge (CPP) Charcoal filters are contained within a double walled steel casing. Ignition of the charcoal will destroy the filters, but the fire will be contained within the casing. All charcoal filtration units will have high temperature alarms which will annunciate in the Control Room. Charcoal filters are pro-vided with water spray systems that will be manually activated if the auto I\, _/'} ignition temperature is reached. There will be no significant release as a result of this activation. All charcoal filtration units and their combustible loading were evaluated in the Fire Hazard Analysis of their particular fire area. The plant design has freah air intakes for all ventilation systems for the General Services Building located in the side of the building. This building houses the bulk of the safety-related equipment. The exhaust plenum and outlet for all of these ventilation systems is located on the roof of the General Services Building. The intake louvers located on the south wall and the exhaust louvers located on the north wall are horizontally separated by 205'-0" and vertically separated by 15'-0". In addition, the air intake for the Control Room is located in three (3) remote areas (one on the building and two (2) remotely located - approximately 2200 feet apart). Air for the Control Poom is monitored for smoke and receives air from an uncontaminated air intake. The remoteness of the building air intakes and exhaust air out-lets will prevent the possibility of contaminating the intake air with the produc ts of combust ion. C.S.g Lighting and Communication Emergency lighting and two-way voice communication for WNP-1 are as follows:

a. Normal lighting systems in the Containment Building and GSB will be supplemented by emergency lighting systems powered by station batteries v i i

C.5-18

                                                                                           ]

WNP- 1 Amendment 3 FPSR and standby diesel generators. This emergency lighting, including exit lighting, will be wired through EMT conduit or by type ALS cable. Special emergency lighting will provide adequate illumination in all areas required for sa fe shutdown of the reac tor. These areas include, for example, the control room complex, remote shutdown panel areas and stairwells, corridors and other access / egress routes thereto. The special emergency lighting will consist of individual lighting units with self-contained eight (8) hour battery packs and automatic chargers. Loss of normal AC power to a unit will cause automatic switching to battery power. In the control room complex and remote shutdown panel areas in particular, the special emergency lighting will consist of strategically chosen normally lit fluorescent lamps. Each battery pack unit, one per lamp, will be fitted with an inverter to provide emergency AC power.

b. Suitable sealed beam battery powered portable hand lights will be made available for use by the fire brigade or other emergency personnel, c.

In addition to telephone systems, there will be fixed emergency communications consisting of sound powered phone jacks at preselected and strategically located stations throughout the plant. Wiring for this system is routed in an embedded raceway system.

d. In addition to telephone systems, there will be two base stations installed to permit the use of portable radio communications units in O

the majority of the plant. O C.5-19 l

I l l WNP- 1 Amendment 3 i FPSR (~'N C.6 Fire Detection and Suppression C.6.a Fire Detection The plant fire detection system design will, as a minimum, comply with NFPA 72D, " Proprietary Signaling Systems." Fire detection systems are located in all fire areas and zones containing safety related and safe shutdown equipment and will give early warning and also actuate some fire suppression systems. The fire detection systems sound audible alarms in the local area and indicate both visually and audibly in the Control Room on the Main Fire Protection Panel (MFPP). Visual indication will be given on the MFPP along with a permanent printed record for all trouble and alarm conditions for each fire zone. Local fire detection panels will be located outside the entrance of the protected area and indicate the fire zone in alarm or trouble. Fire alarms will have a distinctive sound from other plant system alarms. The fire detection and actuation systems will be powered from emergency power supply within each control panel. All components of the MFPP system will have integral emergency power supplies. The MFPP system is designed and installed to meet the requirements for Class A circuits as defined in NFPA 72D, 1975. O) t Local Fire Detection Panels (FDP) which report to the MFPP are designed and installed to meet the requirements of Class "B" circuits as defined in NFPA 72A,

     " Local Protective Signaling Systems." Local panels which activate suppression systems in saf ety related areas utilize Class   "A" wiring for initiation cir-cuits.

NFPA 72E, " Automatic Fire Detectors" is used as a guideline for the selection and installation of fire detectors in the plant. C.6.b Fire Protection Water Supply System The primary water supply for fire protection is the Circulating Water System. This is a recirculating system with no consumptive uses. Water is lost from this system only due to evaporator cooling and blowdown. The fire pump in-stallation conforms to NFPA 20, " Standard for the Installation of Centrifugal Fire Pumps" and consists of three (3) 50% UL listed fire pumps and controllers, two electrically driven and one diesel engine driven, each capable of deliver-ing 2000 gpm. The diesel driven pump has power supply and controls indpendent , f rom the elect ically driven pumps. The pumps are located in the Circulating I Water Tump Hour e in individual rooms whose perimeters have a minimum three j (3) hour fire roting. The pumps feed a common header that is connected to i the fire main loop at two (2) locations -at each end of the pump house and ' is sectionalized outside the pump house by post indicator valves so that the fire main loop can be fed from either, or both, connections. ('~) l LJ C.6-1 i l

WNP- 1 Amendment 3 FPSR The fire pumps take suction from a common sump shared with the four circulating water pumps and the three plant service water pumps. The sump is fed from the three cooling tower basins, each containing over 1.5 million gallons of water. Thecefore the total inventory above the fire pumps suction is over 4.5 million gallons. This level is maintained automatically by the Plant Make-up Water System which consists of two normally operating and one spare, 10,000 gpm pumps taking suction from the Columbia River. Two diesel driven make-up pumps can supply 1,000 gpm each to the fire pump sump in the event of a loss of off-site power. The secondary water supply for fire protection will be provided by a ground level storage tank that will supply three UL listed fire pumps. The water storage tank will contain a minimum of a two hour supply based on the maximum water demand plus 500 gpm for hose streams dedicated for fire protection by a passive means. The fire pump installation is completely separate f rom primary suply pumps and are installed in conformance with NFPA 20. The fire pumps are each 50% pumps, two electrically driven and one diesel engine driven, that pump 2000 gpm each. The complete design for the secondary water supply system has not been completed at this time. Additional details will be provided in the next amendment. Alarms indicating " fire pump runing," " driver not available," and " failure to start," among others, are provided in the control room. The underground fire main loop is designed and installed to furnish the anticipated fire water requirements in conf ormance with NFPA 24, "S tandard for Outside Protection." The pipe installed is cement lined to inhibit internal tuberculation. The Circulating Water System is treated with chlorine to control biofouling and culf uric acid to maintain pil for scale control. The fire system has provisions for flushing. Sections of the main can be isolated, during periods of maintenance and repair by closing approved sectional post indicator valves that are equipped with visual indicators. The fire main system piping exclusively serves the fire protection system. All interior main and branch system control valves are electrically supervised in accordance with NFPA 26, " Supervision of Valves" and indicate on the Fire Protection Panel in t he Cont rol Room. The outside PIVs are not electrically supervised, but all have visual indication of being opened or closed and will be locked in the appropriate position. To assure that the valves are locked in the proper position, an administrative program will be set up to supervise these valves including a strict key con-trol, tamper proof seals, and a periodic preventive maintenance program to provide a visual check of all valves. O C.6-2

WNP- 1 Amendment 3 FPSR (h The hydrants on the plant loop are located approximately 250 feet apart. Ts ,/ Each hydrant is supplied by a lateral from the yard main, and each lateral is provided with a curb box valve. Each hydrant is provided with a hose house which is furnished considering the recommendations of NFPA No. 24. A typical hose house contains 400 feet

      - of 2 1/2" and 200 ft of 1 1/2" hose in 50 foot lenghts. The hose is double jacketed and rubber lined.

All threads used on standpipe risers, hose couplings and hydrants are National Standard Fire Hose Thread and are compatible with equipment used by the DOE fire department. C.6.c Water Sprinkler and Hose Standpipe Systems

1) Water Sprinkler Systems NFPA 13, " Standard for the Installation of Sprinkler System" is utilized for guidance in the design and installation of automatic sprinkler systems. The design and installation of water spray systems utilize NFPA 15, " Standards for Water Spray Fixed Systems" for guidance.

Automatic sprinkler wet pipe or preaction systems, where employed, will be installed to prevent water from damaging any equipment. Areas containing automatic water suppression systems are provided with floor drains and/or

  -     sump pump f acilities.

i (' "s 2) Hose Standpipe Systems The fire protection system has hose stations located throughout all buildings and on all floors, including the Containment, such that all areas can be reached with a maximum of 100 feet of hose. Each hose station consists of a 2 1/2" hose connection with a 2 1/2" valve, 1 1/2" pressure reducer, 100 feet of 1 1/2" woven jacket lined fire hose and suitable nozzle. The hose stations are supplied by standpipes with a minimum diameter of 4". S tandpipes , in general, are in the stairwells with hose stations located outside the stairwell entrances on each floor for Class II use. A 2 1/2" hose connection is located in the stairwell at each flocr for Class I use. Class III stations are located where needed to meet the maximum spacing requirements. The standpipe system in the General Services and Containment Buildings is seismically supported and installed in accordance with ANSI Standard B.31.1 A cross-connection between the standpipe header and a Seismic Category I water system, the Nuclear Service Water System (NSW), is made through a connection with a manually operated valve to provide the standpipe system for the entire GSB Building and Containment Building with a Seismic Category I l water supply. The NSW System is capable of supplying Class II hose streams l O \ v/ C.6-3 1 U

WNP- 1 Amendment 3 FPSR at a reduced pressure. Failure of the fire protection system vill in no way degrade the function of the NSW system. All standpipe hose stations in areas with concentration of electrical equip-ment will be equipped with adjustable fog nozzles approved for use on Class C fires by Factory Mutual and/or listed by Underwriter's Laboratories, Inc. Other hose stations will use hose nozzles appropriate to the equipment and/or area to be protected from fire. The standpipe system design has a header through the General Services Building that is an extension of the yard main system and each header connects with the yard main system at two (2) remote points. The headers are controlled by post indicator and isolation valves so that a single failure of the system does not create a lack of water supply to the building. Sprinkler systems and standpipe systems therefore have indpendent connection to the yard main system through either building header or the yard main itself. Each system takeoff has a separate valve, either OS&Y or other approved shutoff valves, and a water flow alarm. C.6.d Halon Suppression Systems Halon suppression systems utilize Halon 1301 and comply with the requirements of NFPA-12A, "Halon 1301 Fire Extinguishing Systems." A total flooding Halon gas extinguishing system is installed under the raised floor of the computer room. A total flooding Halon gas extinguishing system is installed in the QA Records S torage Vault. The air conditioning and ventilation system for this area has fire dampers in all ducts that will close upon actuation of the Halon system to maintain the concentration. C.6.e Carbon Dioxide Suppression Systems There are no carbon dioxide suppression systems presently utilized at WNP-1.

(3j C.7 CUIDELINES FOR SPECIFIC PLANT AREAS C.7.a Primary and Secondary Containment i The detection system will alarm with a visual indication of the alarmed zone at the local panel located outside the Containment at the personnel hatch. An audible alarm will be given inside the Containment. An audible and visual alarm will be given in the Control Room indicating the fire zone. The detection system consists of ionization and photoelectric detectors. Each of the four (4) containment recirculation ventilation fans is located

      . in an individual fire zone and draws air from the Containment, from its zone, thus causing the detection system in that zone to act as a general alarm if the ventilation system draws smoke prior to another zone's detection system detecting it.

All of the necessary equipment and accessories required to allow the fire brigade to enter the Containment and attack the fire will be located outside the Containment personnel hatch. This equipment will include; self-contained breathing air packs, portable fire extinguishers, including 200 lb. wheeled units, and radiation detec tors. The Containment contains a permanent seismically supported standpipe system with hose stations. Administrative procedures and control will be initiated for use during refuel-ing and maintenance operations in the Containment. They will include provisions [s,- for fire watches and the availability of self-contained breathing units, portable hand fire extinguishers and 200 lb. wheeled fire extinguishers. Each Reactor Coolant Pump Motor contains 397 gallons of lubricating oil. j The major concerns regarding the potential for an oil related fire are an i internal motor fire, or an external fire caused by leakage of oil from the I motor on to the pump. During normal operations the pump casing could be hot 1 enough to cause the oil to auto-ignite. 1 i The probability of a major internal lube oil fire is low because of the absence of a heated surface to ignite the oil and the lack of limited surface area i for burning. The samil amount of oxygen inside the motor would quickly cause the fire to go out. Regarding the potential for an external fire, two principle sources of leakage have been considered on other reactor coolant pump motor designs in the past. One source has been a failure of the piping in the high pressure lube oil system. The other has been a failure of the cooling water line to the oil i reservoir cooler inside the reservoir. The cooling water failure would flood the reservoir causing it to overflow via the overflow nozzles and possibly down the shaf t. Traditionally, a sheet metal drip pan / splash collar which is piped to a collection tank has been used to satisfy the above concerns. O C.7-1

i WNP- 1 Amendment 3 l FPSR The AEG motors which are used on WNP-1 are designed so as to preclude either of these events. All of the high pressure piping is contained within the motor. This eliminates the possibility of external leakage from any type of high pressure lube oil pipe ruptures. Also, the upper and lower bearing reservoirs are provided with large overflows to prevent the oil level from reaching the top of the reservoir standpipe in the event of a cooling water failure inside the reservoirs. The overflows from each pair of reactor coolant pumps lead via seismic Category I piping to a 500 gallon seismic Category 1 collection tank. The tank has a high level alarm and an overflow which is piped to a covered containment sump. This piping is also seismic Category I. In addition, the motors are seismically analyzed to preclude external oil leakage during an earthquake. They have high level alarms in the bearing oil reservoirs and the sight glasses are normally covered and sealed unless actually being used during filling and draining operations. Other design details of the motors are currently being evaluated with B&W to confirm that there are no other credible sources of leakage. C.7 b Control Room Complex The Control Room Complex is designed with 3-hour fire rated perimeter walls, floor, and ceiling, and with equivalent 3-hour fire rated doors. The complex consists of several rooms, including the Computer Room. The Computer Room enclosure is a separate fire area with equivalent 3-hour fire rated barriers. The peripheral rooms which include of fices , kitchen and toilet, are separated with a 1-hour fire rated barrier and are sprinklered. The contents of these rooms are standard combustibles such as paper, wood, plastic, etc. Each room, therefore, will have ionization detectors for early warning alarm sounding in the Control Room and at the Main Fire Protection Panel (HFPP ) . Fire protection within the Control Room will be by portable extinguishers and backed up by hose stations outside the Control Room. In addition, all consoles and cabinets which contain redundant Class IE equip-ment will contain ionization detectors. These detectors will, in an alarm condition, sound signals in the Control Room, illuminate a light on the affected console or cabinet, and alarm at the MFPP. Protection will be by portable extinguishers backed up by hose stations located outside the Control Roma. The hose stations will utilize hoses with electrical type nozzles. All fire alarms in other parts of the plant will alarm in the Control Room on the MFPP and fire fighting direction will originate from there. Breathing appratus will be available in the Control Room for use by Control Room personnel. The Control Room ventilation system is common with the training room, computer room and peripheral rooms. It is supplied with air through one of the three O C.7-2

WNP- 1 Amendment 3 FPSR (o) '/ (3) remotely located intakes. Each intake will have smoke detectors which will indicate in the Control Room, allowing the selection of the cleanest of the three (3) intakes to supply air to the Control Room. Operation of all three (3) intakes will be under the surveillance of Control Room personnel with manual operation selection capability.

Divisional cable separation is accomplished by installing (~'} primary and backup cable systems in separate cable trays as per Regulatory C/ Cuide 1.75. The plant design has four (4) remote and separate entrances to the cable spreading area, two are located on each floor level. The design of the cable spreading area will provide 3-foot wide aisles with 8 ft. high clearances for fire fighting access throughout most of the area. Some double tray ctacks are separated by less than 3 feet, but are accessible from either side of the double stack for fire fighting. The Cable Spreading Room meets the guidelines of Regulatory Guide 1.75. Cables will not be coated with a fire retardant coating because of: the quality of the cable insulation which meets IEEE-383-1974 requirements; the plant's remote shutdown capabilities, and of the automatic wet pipe sprinkler system provided throughout. Also, remote shutdown capability with all cabling independent of the Cable Spreading Room is provided. C.7.d Plant Computer Room The Plant Computer Room, which is not safety related, is part of the Plant Control Room complex. The room itself is contained in 3-hour fire rated fv) C.7-3

8.2 Without Primary Fire Suppression: The fire will be contained to this area by the fire barriers provided and manual fire suppression efforts. 9.0 A_CCIDENTAL OPERATION OF PIRE PROTECTION SYSTEM: 9.1 Equipment

Subject:

MUS and NSW equipment 9.2 Accident Discharge Consequences: Passive barriers and proper location of sprinkler nozzles prevent more than one division from being subject of suppression system discharge and subsequent damage. 10.0 APPENDIX R EVAULATION: 10.1 Major Equipment: Swing pump (MUS-FMP-3C) controls and "B" Train pump (MUS-FMP-2B) controle will be provided with a one hour passive fire barrier. Automatic sprinklers over pumps and laydown area in conjunction with passive barriers will prevent a fire in the area from damaging redundant shutdown equipment.

 /               A curb at the entrance to each pump bay will prevent a flammable
   '>)           liquid spill in the laydown area from entering the pump bays.

Analytical modeling is being done to show that a fire at the f ace of the bay will not damage the pump and driver. Redundant valves in zone SL6-1G are separated by full height walls. Sprinklers are installed at ceiling over cable trays at face of valve cubicles. With one hour passiv barrier around one division of redundant valves, a fire will not damage both divisions. A one hour passive barrier around both MUS-Vl98A and MUS-V199B and related cabling will prevent inadvertent valve operation. There are no fixed combustibles in this zone (SL6-1E) and it is $ separated by concrete walls from remainder of area. Passive barriers on one division of NSW redundant valves and automatic sprinklers in the vicinity will prevent damage to both divisions of equipm it due to an exposure fure (SL6-IF).

10.1 Major Equipment: Required MUS valves (7 total) are located adjacent to containment wall. Valves are approximately 30 feet or more above the floor and are separated by 3 feet or more from each other. A transient fire at floor level (cabling in area is in conduit) will not damage valve operability. The four MUS flow control valves (52A, 52B, 52C and 52D) and flow transmitters (52A, 52B, 52C and 52D) are located at floor level and are separated by 4 to 8 feet. In' order to prevent a transient fire from damaginF the valve operator or transmitters, a one hour barrier around each will be , provided. With the limited fire exposure the barrier D.2-198

Primary suppression in the Turbine Building is as follows: Area Sprinkler 112 seal oil unit Deluge FW pumps Deluge Turbine & Generator bearings Preaction Lube Oil Coolers and Reservior Deluge Air Compressors Wet Pipe Areas under Turbine Generator Wet Pipe Operating Floor In areas not covered by automatic suppression, on an alarm from the detectors the fire brigade will respond using portable extinguishers and hose station facilities and the fire will be rapidly extinguished. In all other areas the fire will be suppressed by the automatic suppression and damage will be limited to the subject area. 8.2 Without Primary Fire Suppression: The Turbine / Water Treatment Building is a steel frame, metal siding structure with three (3) sides exposed to the exterior. The fourth or west side is part of the Isolation Building structure constructed of 3'-0" thick reinforced concrete with equivalent 3-hour fire rated doors. Combustible turbine oils located in the turbine portion of the building are spatially separated from the Isolation Building i wall by the Water Treatment portion of the building which is  ! 70'-0" wide. i a 1 1 I D.4-3

k'N P- 1 Amendment 3 1PSR FIRE HAZARDS ANALYSIS [ V) The lube oil reservoir tank in the Turbine building is housed in an enclosure with a 3-hour fire rating. Combustible resin materials located in the water treatment portion of the building are spatially separated from the Isolation Building wall by a minimum of 3'-0" thickness. The design basis fire will therefore be isolated within the limits of the subject building. There is no safe shutdown system within the subject area. On alarm from detectors, the fire brigade will respond using the secondary suppression (hose station facilities and portable extinguishers) systems. Yard hydrant facilities around the exterior of the subject building are available. 9.0 ACCIDENTAL OPERATION OF FIRE PROTECTION SYSTEM: 9.1 Equipment
