NUCLEAR REGULATORY COMMISSION 2
WASHINGTON, D.C. 20666 4 001
,o SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 39 TO FACILITY OPERATING LICENSE NO. NPF-86 NORTH ATLANTIC ENERGY SERVICE CORPORATION SEABROOK STATION. UNIT NO. I DOCKET NO. 50-443
1.0 INTRODUCTION
By ap)lication dated October 7,1994, North Atlantic Energy Service Corporation (Norti Atlantic /the licensee) aroposed an amendment to the Appendix A Technical S)ecifications for the Seabrooc Station, Unit 1 (Seabrook). The proposed c1anges would remove from the Technical Specifications (TSs) certain audit responsibilities of the Nuclear Safety Audit Review Committee and certain review responsibilities of the Station Operation Review Committee relating to*
the Emergency Plan and the Security Plan and their respective implementing procedures. The proposed changes also would delete the requirements relating to written procedures applicable to these plans.
The proposed changes are consistent with the guidance of Generic Letter 93-07.
2.~0 EVALUATION North Atlantic has proposed changes to TS 6.4.1.6 and 6.4.3.8 which list the review responsibilities of the Station Operation Review Committee (SORC) and audit responsibilities of the Nuclear Safety Audit Review Committee (NSARC) respectively. The proposed changes would remove requirements to review and audit the Emergency Plan and the Security Plan from the TSs since these requirements duplicate the provisions of 10 CFR Part 50 and 10 CFR Part 73.
The review and audit requirements in the TSs would be relocated to the respective plans. North Atlantic also proposed to delete from TS 6.7.1 the requirements relating to written procedures for these plans. The NRC issued guidance to all holders of operating licenses for nuclear power reactors on these proposed changes by Generic Letter 93-07.
Part 50.36 of Title 10 of the Code of Federal Regulations established the regulatory requirements related to the content of TSs. The rule requires that the TSs include items in specific categories, including safety limits, limiting conditions for operation, and surveillance requirements.. However, the rule does not specify the particular requirements to be included in the plant TSs.
The NRC developed criteria, described in the " Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors" (58 FR
, to determine which of the design conditions and associated 39132)illances need te be located in the TSs because the requirement is surve "necessary to obviate the possibility of an abnormal situation or event giving 9505260053 950519 PDR ADOCK 05000443 P
i
. 3 rise to an immediate threat to the public health and safety." Briefly, those criteria are:
(1) detection of abnormal degradation of the reactor coolant pressure boundary, (2) boundary conditions for design basis accidents and transients, (3) primary success paths to prevent or mitigate design basis accidents and transients, and (4) functions determined to be important to risk or operating experience.
The Commission's final policy statement acknowledged that its implementation may result in the relocation of existing TS requirements to licensee controlled documents and programs.
North Atlantic has proposed modifying TS 6.4.1.6 by deleting paragraphs i. and J. which reference the Security Plan and Emergency Plan, respectively, and their implementing procedures under the review responsibilities of the SORC.
North Atlantic has also proposed modifying TS 6.4.3.8 by deleting paragraphs
- k. and 1. which reference the Emergency Plan and the Security Plan respectively, and their implementing procedures under the audit responsibilities of the NSARC. The removed audit and review requirements would be relocated to the res)ective Emergency Plan or the Security Plan.
Additionally, North Atlantic 1as proposed to modify TS 6.7.1 by deleting paragraphs c. and d. which reference written procedures for the implementation of the Security Plan and the Emergency Plan. North Atlantic proposed these changes consistent with the guidance provided in GL 93-07.
s The NRC staff has determined that the requirements discussed above relating to the Emergency Plan and the Security Plan do not satisfy any of the previously stated final )olicy statement criteria which would necessitate that they be included in tie TSs. On this basis, the staff concludes that these requirements do not need to be controlled by the TSs.
In addition, as stated in GL 93-07, 10 CFR Part 50 and 10 CFR Part 73 include provisions that are sufficient to address these requirements. The staff has concluded that the proposed changes to TS 6.4.1.6, 6.4.3.8, and 6.7.1 are, therefore, 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 an administrative rocedure or requirement.
Accordingly, the amendment meets the eli ibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(1 ).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of thi amendment.

5.0 CONCLUSION
The Commission has concluded, based or,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)lations, such I
activities will be conducted in compliance with the Commission's regu and (3) the issuance of the amendment will not be inimical to the common i
defense and security or to the health and safety of the public.
