SUBJECT:

REQUEST FOR APPROVAL OF ALTERNATIVE TO INSPECTION OF REACTOR PRESSURE VESSEL CIRCUMFERENTIAL WELDS IN BRUNSWICK STEAM ELECTRIC PLANT UNIT 1 (TAC NO. MA0345)

By [[letter::BSEP-97-0459, Requests Approval to Use Alternative Requirements for ISI Delineated in ASME Section XI Code Case N-535.Alternative Is Needed to Extend Third Period of Second ten-yr ISI Interval to Coincide W/End of Bsep,Unit 1,refueling Outage 11|letter dated November 17,1997]], Carolina Power & Light Company (CP&L or the licensee) requested NRC approval of an attemative reactor vessel weld examination pursuant to the provisions of 10 CFR 50.55a(a)(3)(i) and 10 CFR 50.55a(g)(6)(ii)(A)(5) for the Brunswick Steam Electric Plant (BSEP) Unit 1 for the next two operating cycles. CP&L has proposed inspections of essentially 100 percent of the longitudinal seem welds in the reactor pressure vessel (RPV) shell and essentially 0 percent of the RPV circumferential seam welds, which will result in partial examination (2 to 3 percent) of the circumferential welds at their points of intersection with the longitudinal welds.

These inspections were proposed as an attemative to the augmented examinations specifed in 10 CFR 50.55a(g)(6)(ii)(A)(2) for circumferential welds and as an attemative to the inservice inspection requirements for circumferential welds in the American Society of Mechanical Engineers (ASME) Code,Section XI,1980 Edition, through Winter 1981 Addenda, for circumferentialwelds.

In Information Notice (IN) 97-63, " Status of NRC Staffs Review of BWRVIP-05," the staff j indicated that it would consider such requests, when technically justified, from BWR licensees who are scheduled to perform inspections of the Boiling Water Reactor (BWR) RPV circumferential welds during the fall 1997 or spring 1998 outage seasons. BWRVIP-05  !

provides BWR Owners Group recommendations for RPV shell weld inspections. l The NRC staff has reviewed the licensee's request and concluded that the Brunswick Unit i RPV can be operated during the next two operating periods with an acceptable level of quality N and safety and the inspection of the circumferential welds can be delayed for two operating periods. Therefore, the proposed attemative is authorized pursuant to 10 CFR 50.55a(a)(3)(i).
