Docket No. 50-443 NYN-98070 United States Nuclear Regulatory Commission Attention: Document Control Desk Washington, D.C. 20555 Seabrook Station License Amendment Request 98-05,
" Changes in Technical Specification Surveillance Intervals To Accommodate A 24-Month Fuel Qvele Per Generic Letter 91-04" Submittal No. 4 North Atlantic Energy Service Corporation (North Atlantic) has enclosed herein License Amendment Request (LAR) 98-05. LAR 98-05 is submitted pursuant to the requirements of 10CFR50.90 and 10CFR50.4.
LAR 98-05 is the fourth submittal in a planned series of License Amendment Requests which propose changes to the Seabrook Station Technical Specifications to accommodate fuel cycles of up to 24 months. The proposed changes are associated with surveillance requirements that are currently performed at each 18-month or other specified outage interval. This License Amendment Request has been prepared in accordance with the generic guidance contained in NRC Generic Letter (GL) 91-04,
" Changes In Technical Specification Surveillance Intervals To Accommodate A 24-Month Fuel Cycle."
Technical evaluations of each proposed increase in surveillance interval support the conclusion that the effect on plant safety is insignificant. Historical preventative and corrective maintenance records, refueling surveillance data, and other testing performed on the surveilled components, as well as, a failure mode analysis, validate the conclusions. In addition, the performance of the referenced surveillance at the bounding surveillance interval of 24 months plus 25% extension (30 months) does not invalidate assumptions in the plant licensing basis.
LAR 98-05 has been reviewed and approved by the Station Operation Review Committee and the Nuclear Safety Audit Review Committee.
