SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 37 TO FACILITY OPERATING LICENSE NO. NPF-86 NORTH ATLANTIC ENERGY SERVICE CORPORATIOR SEABROOK STATION. UNIT NO. 1 DOCKET NO. 50-443
1.0 INTRODUCTION
By letter dated January 25, 1995, North Atlantic Energy Service Corporation (North Atlantic) submitted a proposed change to the Seabrook Station, Unit No.
1 (Seabrook) Technical Specifications (TS). The proposed change would revise Surveillance Requirement (SR) 4.6.1.2.a of the TS to replace the prescribed number of ILRTs to be performed and the associated schedule with the requirement to conduct ILRTs at intervals as specified in 10 CFR Part 50, Appendix J.
On May 16, 1995, North Atlantic orally requested that a clarifying phrase also be added to indicate the applicability of approved exemptions with regard to the SR 4.6.1.2.a.
The oral request does not change the initial proposed no significant hazards consideration determination.
2.0 EyALUATION Surveillance Requirement 4.6.1.2.a currently paraphrases 10 CFR Part 50, Appendix J, for the required schedule for performing containment Integrated Leakage Rate Tests (ILRTs).
The change would revise Surveillance Requirement 4.6.1.2.a by deleting the number of tests to be performed in each 10-year service period and the specified allowable interval between successive ILRTs.
The modified surveillance requirement would require Type A tests to be conducted at intervals specified in 10 CFR Part 50, Appendix J.
The proposed a
change is administrative.
Surveillance Requirement 3.6.1.1 of the revised Standard Technical Specifications for Westinghouse plants, NUREG-1431, states:
Perform required visual examinations and leakage rate testing, in accordance with 10 CFR, Appendix J, as modified by approved exemptions.
The proposed wording for SR 4.6.1.2.a is consistent with that used in the revised Standard Technical Specifications for the required frequency of the ILRT.
(Requirements for visual examinations of the containment are included in SR 4.6.1.6 of the Seabrook TS.)
Since the change is administrative in nature, in that it references the controlling regulations directly rather than paraphrasing the regulation, the NRC staff finds the proposed change to be acceptable. North Atlantic's January 25, 1995, request did not propose the i

, addition of a reference to approved exemptions to. Appendix J.
However, on May 16, 1995, North Atlantic orally requested the addition of the phrase, as modified by approved exemptions, to clarify the applicability of the provisions of any approved exemption with regard to TS requirements. The staff finds the clarifying phrase acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the New Hampshire and Massachusetts State officials were notified of the proposed issuance of the amendment. The State officials had no comments.

4.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a surveillance requirement. The NRC 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 exposure. 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 (60 FR 8754).
Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR i
51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

5.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
