Dear Mr. O'Reilly:
Pursuant to the requirements of the Technical Specifications Section E.4.d, a failure of an engineered safety feature that causes or threatens to ceuse the feature or system to be incapable of performing its intended function is reported as Abnormal Occurrence 50-29/75-09.
At 0720 on 9/6/75, with the plant ooerating at normal steady state power, a blown fuse in the'No.1 Emergency Diesel Generator DC starting circuit resulted from the overheating and subsequent fusing of a starting circuit supervisory lamp.
Immediately after the incident the No. 2 and Mc. 3 Emergency Diesel Generators were started and test run for five minutes thus veri-fying their operability.
At 1006 the same day a repair was completed and the No.1 Emergency Diesel Generator was test run and declared fully operational.
l A formal 10 day report will follow.
Very truly yours,
