SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT'NO.136 TO FACILITY OPERATING LICENSE N0. DPR-71 AND AMENDMENT N0.166 TO FACILITY OPERATING LICENSE NO. DPR-62 CAROLINA POWER & LIGHT COMPANY, et al.
BRUNSWICK STEAM ELECTRIC PLANT, UNITS 1 AND 2 DOCKET NOS. 50-325 AND 50-324
1.0 INTRODUCTION
By letter dated May 1,1989, Carolina Power & Light Cocpany (the licensee) requested changes to the Brunswick Steam Electric Plant, Units 1 and 2, Technical Specifications (TS) 4.6.1.2, Containment Leakage, to delete the requirement to use only the mass point method for Type A containment integrated leak rate testing. The above change to the TS has been proposed by the licensee to allow for use of any containment leak rate determination method permitted by 10 CFR Part 50, Appendix J.
2.0 DISCUSSION AND EVALUATION Appendix J to 10 CFR Part 50 entitled " Primary Reactor Containment Leakage Testing for Water - Cooled Power Reactors" permits three methods for determining containment leakage rates. These are point-to-point, total time, and mass point. Details associated with the point-to-point and total time methods are contained in ANSI N45.4-1972, and the mass point method is addressed in ANSI /ANS 56.8-1981 (revised 1967).
The licensee's present requirement to use only the mass point method, as specified in ANSI /ANS 56.8-1981, for Type A containment integrated leak rate testing was approved by the staff by letter and amendments dated February 17, 1988. Prior to February 17, 1988, the licensee was required by TS to use the point-to-point or total time methods described in ANSI N45.4-1972.
The licensee realized after the amendments were issued that the use of the point-to-point or total time method was precluded. The licensee stated in the May 1, 1989 application that this was not intended, although it was what was requested.
The licensee is now requesting to reinstate use of the point-to-point or total time methods in the TS.
The licensee has indicated that, when the total time method is utilized, a reduced duration Type A integrated leak rate test may be desirable.
If so, it will be conducted using the criteria contained in Bechtel Topical Report BN-TOP-1, Revision 1, dated November 1, 1972. The use of the Bechtel Topical Report at Brunswick was previously approved by the staff in a letter to the licensee dated December 9, 1983.
The continued use of BN-TOP-1, Revision 1 at Brunswick is acceptable.

Based upon the above, we conclude that the use of any methodology permitted by Appendix J is acceptable, as is the proposed change to TS 4.6.1.2.
3.0 ENVIRONMENTAL CONSIDERATION
S These amendments change a requirement with respect to installation or use of a facility component located within the restricted areas as defined in 10 CFR Part 20 and changes to the surveillance requirements. The staff has determined that these amendments involve no significant increase in the amounts,- and no significant change in the types, of any effluents that may be released off site; and that there is no significant increase in individual or cumulative occupational radiation exposure. The Comission has previously issued a proposed finding that these amendments involve no significant hazards consideration, and there has been no public comment on such finding.
Accordingly, these amendments meet 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 these amendments.
4.0 CONCLUSION
The Comission made a proposed determination that these amendments involve no significant hazards consideration which was published in the Federal Register (54 FR 25369) on June 14, 1989, and consulted with the State of North Carolina. No public coments or requests for hearing were received, and the State of North Carolina did not have any comments.
The staff 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, and (2) such activities will be conducted in compliance with the Com-mission's regulations, and the issuance of the amendments will not be inimical to the comon defense and security or to the health and safety of the public.
