Docket Nos. 50-250 OLA-1, 50-251 OLA-1

Dear Members of the Board:

Last Friday, March 15, 1985, Florida Power & Light Company (FPL) was informed by Westinghouse Electric Corporation' that, on March 9, 1985, it was determined necessary to revise the ECCS evaluation model procedure by which the core flooding rate information generated by the WREFLOOD code is introduced into the BART heat transfer coefficient calculation. This change was made after Westinghouse discovered, while performing work unrelated to Turkey Point Units 3 and 4, that the procedure for introducing the flooding rate information into the BART code allowed information inconsistent with the WREFLOOD, results to be used, thereby resulting in lower calculated peak clad temperature (PCT) than otherwise would have been calculated in some cases. FPL has been informed that preliminary ECCS performance reanalysis utilizing the revised procedure results in a calculated PCT higher than the 1972 'F calculated PCT indicated in the August 10, 1984 8503200502 850318
