DOCKET NO. 50-313 INTRODUCTION By letter dated October 19,19P9, Arkansas Power and Light Company (AP&L or the i
licensee) recutsted an amendnent to the Technical $pecificaticos (TSs) appended i
to Facility Crerating License No. DPR 51 for Arkansas Nuclear One, Unit 1 (ANC-1). The pro?osed amendment would change TS 3.2.1.2 regarding the required terperature for tie piping and valves necessary to establish a fick path from the boric acid addition tank to the maLeup system. The required temperature for the pipir.g and valves is changed fron 3 comparison to the tank temperature to a tenperature cf at least 10'F above the crystallization temperature for the i
cctcentratior. iri the tank.
EVALUATION i
The purpcse for TS 3.2.1.2 is to ensure that the boric acid addition tank (BAAT) tr.d its asscciated piping and valves are kept at least 10'T above the crystalli-4 24 tion temperature for the concentration present, to assure a flow of beric acid is aSailable when needed. The current TS says tha.t the BAAT temperature shall te at least 10'F above the crystallization temperature, ar.d this is consistent with its purpose. However, the current TS also says that the system (associated) piping and valves shall have at least the sarne tem >erature as the BAAT. This r.ey require an unnecessarily high temperature for tse associated piping and valves if the BAA1 is significantly more than 10'r ateve the crystallization temperature (i.e., in this instance the current TS hculd also require the temperature for the associated piping and valves to be significantly more than 10'F above the crystallization temperature). Therefore, the staff finds.that the prcposed 15 are censistent with the purpose for TS 3.2.1.2, consistent with the current bases for TS 3.2.1.2, and adds clarity to TS 3.2.1.2.
Accordingly, the proposed revision tc TS 3.2.1.2 is acceptable.

ENVIRONMENTAL CONSIDERATION L
The amendment involves a change in a requiren4nt with respect to the installa-tion or use of a facility component located within the restricted area as defined in 10 CFR Part 20 end changes in surveillance requirements. The staff has determined that the amendment involves no significant increase in the amounts, trd no significant change in the types, of any effluttts-that may be released offsite, and that there is ne significant increase in individual or cutulative occupation 61 radiation expost es. The Comission has previously issued a proposed finding that the amendment involves no significant hazards 9005160321 900418 ADOCK0500g3-l DR.
consideraticn and there has been no public comment on such finding. Accordingly, the amendnent meets the eligibility criteria for categorical exclusion set forthin10CFRSection51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environs *r.tal impact statement or environnental assessrent need be prepared in connection with the issuance of the atendment.
CONCLUSION The staff has concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the will net be endangered by operation in the proposed manner, and (2) public such activities will be ccnducted in compliance with the Comr.ission's regulations, ard the issuance of the amendnent will net be inimical to the comr.on defense and security or to the health and safety of the public.
