Dear Mr. O'Reilly:

TENNESSEE VALLEY AUTHORITY - BROWNS FERRY NUCLEAR PLANT UNITS 1 AND 2 -

DOCKET NOS. 50-259 AND -260 - FACILITY OPERATING LICENSES DPR-33 AND 10 CFR 21 REPORT During receipt inspection of items bought on contract No. 341119, it was discovered that numerous problems existed with ELMA power supplies (part No. 164CS261P004). These were bought as spare parts for two modifications.

Among the problems fcund were defective wiring, cold solder joints, and overall poor quality workmanship. The power supplies have thus far been installed only in the reactor protection system and are in a " fail safe" .

co7 figuration. Of those installed, eight in unit 1 and eight in unit 2, j all have been checked and defects repaired.

This problem is reportable under 10 CFR 21 and was reported to me on January ' 10, 1984. The enclosed part 21 report contains additional information about this matter.

Very truly yours, TENF SSEE VALLEY AUTHORITY B&
