Update Relating to Notification of Potential Part 21 Gentlemen:

This letter is a progress report on Wyle'sletter dated September 29,1992 " Notification by Wyle Laboratories of a potential defect of a basic component."

As previously noted on January 11, 1991, Wyle Laboratories delivered eight (8) Solenoid Manifold Assemblies, P/N C6930-060, Wyle Codes GRE 001 through GRE-008, manufactured-by Automatic Valve (AVC) o/Novi, Michigan to the Tennessee Valley Authority's Browns Ferry Nuclear Plant.

These Solenoid Manifold Assemblies were certified by Wyle Report Number 30081-99 (Job Number 41430) through a Commercial Grade Dedication Program to be qualified to the requirements of Wyle Report 17514-1, Revision A, which included NUREG 0588, Categorr I.

The potential defect is that Wyle Report 30081-99 does not provide sufficient evidence that the above noted serial numbers are qualified by similarity to Wyle Report 17514-1, Revision A.

Wyle had supplied these Solenoid Manifold Assemblies only to Browns Ferry, as noted above.

TVA returned. to Wyle all eight of the Solenoid Manifold c.ssemblics in question on October 5,1992, and they are now held at Wyle awaiting completion of the similarity analysis.

Wyle and AVC met on October 23, 1992 to identify the outstanding docuruents needed to complete the similarity analysis.

Wyle anticipates completion of the similarity analysis by the end of November 1992.

Sincerely, WYLE LABORATORIES Eastern Operations Edward W. Smith
