Serial No.: NO-81-1631 Mr. Darrell G. Eisenhut, Director Division of Licensing United States Nuclear Regulatory Commission Washin'gton, 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 NUREG-0737 ITDI II.D.1, " RELIEF AND SAFETY VALVE TEST REQUIREMENT"

Dear Mr. Eisenhut:

In response to NUREG-0737, " Clarification of TMI Action Plan Requirements", Item II.D.1, " Relief and Safety Valve (S/RV) Testing",

this letter provides the final test results which demonstrate the operatior.al adequacy of the.S/RVs for the Brunswick Steam Electric Plant. In addition, the adequacy of the S/RV discharge piping and

. supports-has also been demonstrated. These final test results are contained in NEDE-24988-P, " Analysis of Generic BWR Safety / Relief Valva Operability Test Results" which was submitted to the NRC by the BWR Owners' Group on September 25, 1981. Carolina Power & Light Company is a

. participant in the BWR Owners' Group generic S/RV operability test

-program.

The Brunswick Plant employs the Target Rock type of S/RV, Model Nos. 7467F and 7567F. The applicability of the generic ' test results to this plant's S/RVs has already been demonstrated in CP&L's letter dated June 30, 1981. A review of the test report shows that the operacional-adequacy of the S/RV's and the piping and supports for the Brunswick Plant has been demonstrated for the conditions d..ined in Item II.D.1 The submittal of NEDE-24988-P and this letter satisfies the October 1, 1981 and January 1, 1982 submittal requirements of Item II.D.1 and completes CP&L efforts on this item.

Table 1-2 of Appendix A of the subject NEDE Report shows that Brunewick Unit 2 has Model No. 7567F S/RVs installed; this is a typographical error. Brunswick Unit 2 currently has Model No. 7467F S/RVs installed.

However, during the next refuellng outage, Model No. 7567F S/RVs will be installed. This error does not affect the validity of the final test results since both Model No. 7467F and 7567F S/RVs meet the test criteria.
