SUMMARY

OF OPERATING EXPERIENCE DOCKET NO. 50-282 UNIT PRAIRIE ISLAND NO.1 DATE DECEMBER 4, 1995 COMPLETED BY DALE DUGSTAD TELEPHONE 612-388-1121-4376 MONTH: NOVEMBER 1995 Unit one was base loaded this month, there were no shutdowns or power reductions.

On the 17th radiation monitoring instrument indications of steam generator tube leakage increased sufficiently to require increased operator awareness, sampling, and trending. The leakage was confirmed by radiochemical analysis to be in 12 Steam Generator. Special monitoring is continuing. The leakage indications have decreased slightly since November 22 and is now a factor of 100 below the Tech Spec limit.

CURRENT CONTINUOUS OPERATING RUN iF 285 DAYS.
