SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.100TO FACILITY OPERATING LICENSE NO. DPR-51 ARKANSAS POWER AND LIGHT COMPANY ARKANSAS NUCLEAR ONE, UNIT NO. 1 DOCKET N0. 50-313 INTRODUCTION By [[letter::1CAN018601, Application for Amend to License DPR-51,revising Tech Specs to Delete Snubber Listing,Per Generic Ltr 84-13 & Results of Baseline Surveillances of safety-related Hydraulic & Mechanical Snubbers.Fee Paid|letter dated January 24, 1986]], Arkansas Power and Light Company (AP&L or the licensee) requested amendment to the Technical Specifications (TSs) appended to Facility Operating License No. DPR-51 for Arkansas Nuclear One, Unit No. 1 (ANO-1). The proposed amendment would delete the tabular listing (Tables 3.16-1 and 3.16-2) of shock suppressors (snubbers) and add the criteria specifying which snubbers are required to be operable and which snubbers are exempted from the requirements of Specification 3.16.
The licensee's application was made in response to the Commission's Generic Letter 84-13 " Technical Specification for Snubbers," dated May 3,1984. These changes are expected to eliminate the need for frequent TS amendments to incorporate changes in the snubber listings.
,1, EVALUATION The NRC staff indicated in the aforementioned Generic Letter that it had reassessed the inclusion of snubber listings within the TSs and concluded that such listings were not necessary provided the snubber TSs are modified to specify which snubbers are required to be operable. The licensee's requested changes to the TSs would delete the tabular listings of snubbers and add the criteria requiring all snubbers operable except the snubbers on nonsafety-related systems whose failures would have no adverse effects on any safety-related system.
l We have reviewed the current TSs together with the proposed changes and compared these changes with model TSs provided in the Generic Letter.
l From our review, we find that the proposed changes are administrative in nature and do not authorize any physical change to the plant's safety-related structures, systems or components. The proposed changes would not in any way reduce availability of those snubbers which are provided to ensure that the structural integrity of the reactor coolant system and all other safety-related systems is maintained during and following a seismic or other event initiating dynamic loads.
Based on the above discussions and the fact that the proposed changes are consistent with guidance provided in the Generic Letter, we havt determined that the proposed changes are acceptable.

4 2-ENVIRONMENTAL CONSIDERATION This amendment involves changes relating to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. We have 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 exposure. The Commission has previously issued a proposed finding that this amendrent involves no significant hazards consideration and there has been no public comment on such finding. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
CONCLUSION We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the will not be endangered by operation in the proposed manner, and (2) public such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
