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 letter, J. E. Gilleland to Donald F. Knuth.

We have not yet been able to complete the final report on this potential deficiency. The manufacturer is continuing his investigation of the deficiency. Our final report, which we expect to submit by August 12, 1974, will contain information received from the manufacturer, analyses of the safety implications, and the corrective actions taken.

Very truly yours, J. E. Gilleland
