1 Attachment SLNRC 80-40 Page Seven Callaway Responses to Acceptance Review Questions 310.01 Discuss the mineral rights for all land.within the Callaway exclusion area.
Response
Union Electric owns all land within the exclusion area. The nature and source of authority to determine all activities on this property is by virtue of the rights of ownership thereof. As the exclusion area lands are owned in fee simple, Union Electric has complete ownership of the minerals on and under their lands.
310.02 Discuss any recreational areas within the Callaway site boundary.
Resoonse Various types of public use or development are permitted within the Union Electric property boundaries. Public use is governed by Union Electric policy and NRC regulations relating to the Protected Zone, the Exclusion Zone, and the Restricted Zone. The anticipated use within these zones during the operating life of the plant is discussed below.
The Protected Zone is a fenced area surrounding the reactor building and safety-related f acilities wit'nin the plant site area. This area is covered by plant security and access is granted only to authorized personnel.
The Exclusion Zone is the area around the plant to a radial distance of 1,200 meters. Union Electric retains control of this area, and residence in this zone is prchibited.
No de-velopments attracting uncontrolled public activity in or en-couraging casual public entry into the area are permitted.
The Restricted Zone includes all property defined by Union Electric as " plant site area" (see FSAR Site Addendum Figure 2.1-2forthisboundary). No residence or dairying opera-tions will be permitted within this zone during plant opera-tion. Developments with public attractions are permitted within this zone outside the Exclusion Zone.
Within the Union Electric ownership area, outside the plant site area, residence is permitted and developments may in-clude public attractions.
In cooperation with Union Electric, the Missouri Department of Conservation in 1976 prepared a plan for the development
Attachment to SLNRC 80-40 Page Eight and management of the forest, fish, and wildlife resources within the Callaway Plant property. Because of the zone controls and the need to effect evacuation procedures in the event of postulated accidental radiation releases, the land-use programs ultimately recommended for the Callaway Plant site are of a low-intensity nature. Recommendations included the f-110 wing: forest management, agriculture, research, wildlife management, hunting, fishing, picnicking, vistas and special areas.
The plan is flexible, and recommended activities can be further emphasized or modified to accommo-date additional priorities or restrictions.
In 1977, Union Electric and the Missouri Conservation Commis-sion entered into an agreement for an initial 5-year manage-ment plan that would be self-supporting and less intensive than the original plan. This plan presently allows public recreational use on designated lands within the Callaway Plant property coundaries; however, camping and use of firearms (firing a single projectile) are not permitted. User data on the Reform Wildlife Management Area is given in FSAR Sec-tion 2.1.3.3.
310.03 Explain the statement in Section 2.1.1.3.1 which roads
" Future developments may include public attractions without entry restriction".
Response
The statement means that the general public will be allowed to enter the restricted area to take advantage of public attractions as described in the response to item 310.02, with-out security restrictions.
310.04 Discuss the projections of industrial growth (2.2.2.6).
Response
The Callaway Plant is located in a sparsely populated rural area, with little existing or projected urban or industrial development within a 5-mile radius.
The primary land use trend in Callaway County has been the continued abandonment and consolidation of farms. Approxi-mately seven percent of the county's land area went out of farm production within the ten-year period from 1964 to 1974.
No trends have been identified that would disturb the rural agriculture and forested characteristics pre 1ent today within five miles of the Callaway Plant. This projection is based on population projections and trends observed over several years. A field reconnaissance by Dames & Moore in 1979 noted only minor new developments since 1973 within five miles of
Attachment to SLNRC 80- 40 Page Nine the Callaway Plant, not including site construction activi-ties. New developments include approximately six homes, two taverns, four small trailer parks, two gas stations, a cafe,
.and two small trucking companies. A review of 1979 aerial '
photographs indicated a conversion of approximately 1,240 acres of pasture to croplard within five miles of the Callaway Plunt since 1973. Changer, in all other land use types were less than 1 percent during the same period.
310.05 Olscuss chlorine storage including volumes and location at the Callawa" site.
Resoonse No gaseous or liquid chlorine is stored or used at the Callaway Site.
Sodium hypochlorite solution is added to the Circulating and Service Water Systems to prevent the systems from fouling with organic growths.
The sodium hypochlorite is produced on-site using a packaged electrolytic generation system. The hypochlorite generation system, along with other chemical feed equipment, is located in the Cooling Water Chemical Control System Building which is near the Circulating and Service Water Pumphouse adjacent to the natural draft cooling tower. Rock salt is used as a raw material to produce a 0.8% sodium hypochlorite solution.
Approximately 17,500 lb/ day of rock salt will be used at max-imum system capacity, which is 5,000 lb/ day of equivalent available chlorine. Rock salt is stored in two brinemaking tanks. The upper portion of each tank provides dry salt stor-age. Water is introduced in the lower portion to produce a saturated brine solution. The brine is diluted with softened water before entering the electrolytic cell, where the con-version to sodium hypochl9 rite occurs. The hypochlorite so-lution is pumped from the cell to three 25,000-gallon vertical storage tanks. Centrifugal pumps feed the hypochlorite to the circulating and service water pump intake bays. The hypo-chlorite circulates through the system being treated and the cooling tower before entering the blowdown discharge stream.
