Q le FLORIDA POWER & LIGHT COMPANY NaI.ch 21, 1983 L-83-164 Office of Nuclear Reactor Regulations Attention: Mr. Darrell G. Eisenhut, Director Division of Licensing U. S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Eisenhut:

Re: ST. LUCIE UNIT NO. 2 DOCKET NO. 50-389 RPS OPERABILITY REPORT SUPPLEMENT 1 In our FP&L letter, L-83-130, dated March 9, 1983, FP&L formally submitted documentation regarding the RPS Cabinet Operability Report. The infor-mation provided in that letter was previously reviewed by the NRC and its contractor. EG&G. In their review of the documentation, they had found the method used, to derate the modules as unacceptable.

FP&L, on March 10, 1983, held a meeting with members of your staff, EG&G and Combustion Engineering to discuss the frequency"dependent derat-ing method used in the original analytical justification of the CPC and NI modules. In that meeting, a revised procedu e to derate the modules was established with the NRC's and EG&G's concurrence.

Attached is FP&L's revised analytical justification of the seismic test

.adequacy of the St. Lucie 2 CPC and NI modules located in the RPS cabinets which utilizes the derating method approved and developed in the March 10, 1983 meeting.

'I Should you have any questions regarding this matter, please contact us accordingly.

Very p d. A.~

truly yours, Robert E. Uhrig goo I Vice President Advanced Systems and Technology REU/RJS/PPC/rms 83032i
