Subject:

10 CFH 21 Report by Combustion Engineering on Target Rock Solenoid Activated Valves Models 77L-001 and 77L-003 dated November 8, 1982, Number LD-82-087

a) Telephone Conversation T. Lee /T. Crowley June 20, 1983 b) Target Rock Corporation Letter E-16612 dated June 7, 1983

Dear Mr. DeYoung:

In response to AY. Lee's telephone request, Reference al, we are includ-Ing further clarification of our position regarding reported equipment failures during qualification testing performed by Combustion Engineer-ing.

The testing performed by C. E. was conducted to a C. E. interpretation of the requirements of NUREG 0588 and was designed to be plant specific for the Palo Verde plant. Other utilities using simifar Target Rock de-signs have reviewed their qualification status and determined that there is no conflict with NUREG 0588. Further, Arizona Public Service has determined that the results of the test program are not applicable to the balance of plant valves. However, in conjunction with the valves supplied to Palo Verde through C.E., Target Rock is supporting a retro-fit program incorporating C.E.'s requirements consistent with C.E.'s in-terpretation of the results of the qualification test conducted for use in the NSSS system.

We would be pleased to discuss this further with you at your convenience.

Very truly yours, TARGET ROCK CORPORATION
