EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION-l RE1ATED TO AMENDMENT NO.136 T0 i p' FACILITY OPERATING LICENSE NO. DPR-51 ENTERGY OPERATIONS. INC. ARKANSAS NUCLEAR ONE. UNIT-NO. 1 i V' DOCKET NO. 50-313 3 INTRODUCTION l By letter dated March 2,1990, Arkansas Power and Light Company (AP&L) requested L - an amendment to the Technical Specifications (TS) appended to Facility L, , Operating License No. DPR-51 for Arkansas Nuclear One, Unit 1 (ANO-1). The proposed amendment would constitute several changes to Section 4.21 of the Arkansas Nuclear One, Unit 11(ANO-1) Technical Specifications. Specifications-L 4.21.1;and 4.21.2 would be deleted and 4.21.3 would be renumbered to 4.21.1. l All-of the sprinkler systems previously covered by Specifications 4.21.1~, 4 -4.21.2, and 4.21.3 would be included in the new 4.21.1 Specification. Require- ~ ments for surveillance testing of the Hallway El 372 (Zone 98-J) Sprinkler i i System and the Condensate Demineralizer Area. Sprinkler System would be added to Specification 4.21.1. The Bases would also be changed to reflect these new requiremaints. In~ addition. the amendment would revise the Bases to more accuratrly describe the sprinkler systems of the emergency diesel generator L room, diesel generator fuel vault, cable spreading room, and four cable E ' penetration rooms as installed, and the amendment would also standardize the surveillance requirements for these-systems.: EVALVAT10h I Section 3.18,_ Fire' Suppression Sprinkler System, requires that sprinkler systems-L are operable to ensure that fire suppression is available to safety-related l-equipment located in each of the four reactor building cable penetration areas, f each of the four cable penetration rooms, each of'the two emergencytdiesel 4 L generator rooms, the cable spreading room, each of the two: diesel generator fuel L vaults,' Hallway El 372, and the condensate demineralizer~ area. However, no l L surveillance' requirements.for Hallway El 372 and the condensate demineralizer t _ area existed in Section 4.21. AP&L proposed to revise Section 4.21 to include _ surveillance' requirements for Hallway E1.372 (Zone.98-J) and the condensate 'I L demineralizer area. LThe staff finds the inclusion of the surveillance require-L ments acceptable because the revised TS will ensure that the functionality of. E the sprinkler system is maintained in all required areas. L The' revised Specification 4.21.1 will demonstrate operability by verifying that each system is aligned to the fire pump at least once every 31 days, by requir-t ing;that the testable valves in the flow path for each system are cycled once per 12 months, and by inspecting the spray nozzles and headers for each system j h 9010250352 901018 gDR ADocaosooga

(' llO 2 ? 4 once per 18 nonths. The staff finds the revised specification to be acceptable s because it adds requirements for additional surveillances of the specified i fire protection systems and it standardizes the surveillance requirements for these systems. ~ Regarding the Bases, the staff informed the licensee that the Bases proposed in the March 2,1990 letter, which described the different types of sprinkler systems, would benefit from some additional minor clarifications to ensure that the descriptions are accurate and consistent. The licensee agreed with the staff's suggestion and verbally proposed several minor revisions to the Bases. The staff has reviewed these revisions and finds them to be acceptable as well. These revisions are reflected in the amended page. ENVIRONMENTAL CONSIDERATION i The amendment involves a change in a requirement with respect to the installa. tion or use of a facility component located within the restricted area as i defined in 10 CFR Part 20 and changes in surveillance requirements. The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in.the types, of any effluents that may be - released offsite,.and that there is no significant increase in individual or cumulative occupational radiation exposures. The Commission has previously. issued a proposed finding that the amendment involves no significant hazards consideration and'there has been no public comment on such finding. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forthin10CFRSection51.22(c)(9). Pursuantto10CFR51.22(b),noenvironmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment. -CONCLUSION The staff has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public-iwill not:be endangered by. operation in the proposed manner, and (2).such activities will be conducted in compliance with the Commission's regulations, and the issuance of-the amendment will not be inimical to the common defense and security or to the health and safety of the public.
