Dear Mr. Knuth:
BROWNS FERRY NUCLEAR PLANT UNITS 2 AND 3 - POTENTIAL DESIGN DEFICIENCY IN VALVE YOKE TO MOTOR MOUNT WELD Initial report of the subject potential deficiency was made on May 14, 1974, and was followed by our June 14, July 15, and August 12 letters, J. E. Gilleland to Donald F. Knuth. Because the yoke to motor base welds of FCV-74-58 in unit 1 failed, similar valves (FCV's 74-58 and 74-72) in units 2 and 3 may be subject to the same type of failure.
The investigation of the problem is continuing, and we have scheduled some testing for unit 3 in December. After the tests have been run and the results have been analyzed, we will forward to you the final report on this potential deficiency. We expect that we should be able to provide the report by January 15, 1975.
1 Very truly yours, 1
