Mr. T. A. Ippolito, Chief Operating Reactors Branch No. 3 United States Nuclear Regulatory Commission Washington, D. C.
20555 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NOS. 1 AND 2 DOCKET NOS. 50-325 AND 50-324 LICENSE NOS. DPR-71 AND DPR-62 SUPPRESSION POOL - REACTOR BUILDING VACUUM BREAKERS REQUEST FOR TECHNICAL SPECIFICATION CHANGE
Dear Mr. Ippolito:
In accordance with the Code of Federal Regulations, Title 10, Part 2.101 and Part 50.90, Carolina Power & Light Company (CP&L) hereby requesto a revision to the Technical Specifications for the Brunswick Steam Electric Plant (BSEP) Unit Nos. 1 and 2.
These changes are necessary to comply with the request from your December 11, 1978, letter and to allow implementation of permanent modifications to the BSEP suppression pool-reactor building vacuum breaker lines as described in our letter to you dated December 29, 1978. Revised Technical Specification pages are attached with changes marked by a vertical bar in the right-hand margin.
Our present plans are to inctall these modifications during the present refueling outage on BSEP Unit 1 and during the upcoming refueling outage on BSEP Unit 2.
In accordance with 10CFR170.12(c), we have determined that this request constitutes one Class III amendment and one Class I amendment because it involves a single technical issue. Therefore, our check for $4,400 is enclosed as payment for these amendment fees.
