FLORIDA POWER & LIGHT COMPANY llQV 8 1885 L-85-030 Office of Nuclear Reactor Regulation Attention: Mr. Edward 3. Butcher, Acting Chief Operating Reactors Branch Ij3 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D.C. 20555
Dear Mr. Butcher:
Re: St. Lucie Unit No. 1 Docket No. 50-335-LOCA-ECCS Anal sis Florida Power 2 Light Company's (FPL) letter to NRC, L-85-331, dated August 27, 1985, provided the details on an input error in the St. Lucie Unit No..l LOCA-ECCS analysis performed by Exxon Nuclear Company, Inc. (ENC). ENC corrected the input error and completed a re-analysis using current NRC approved methodologies. As a result of the re-analysis, FPL requested an amendment to the St. Lucie Unit No. 1 Technical Specifications (L-85-396, dated October 17, 1985) to assure continued compliance with 10 CFR 50.06 criteria. In support of the proposed license amendment, the attached ENC Report XN-NF-85-117 provides the documentation to support the operating Linear Heat. Generation Rate (LHGR) limits which meet the 10 CFR 50.06 criteria. Partial results of the LOCA break spectrum calculations sufficient to determine the limiting break LOCA are included, and results of the studies which provide the axially dependent operating LHGR limits are documented. The completed results of the LOCA-ECCS large break spectrum and the exposure calculations willbe forwarded in a supplement to this report in early December 1985. Very truly yours, /~~3. W.
