Gentlemen:

The preliminary review of your initial response to IE Bulletin 85-03

" Motor-0perated Valve Common Mode Failures During Plant Transients Due To Improper Switch Settings" indicates that it does not contain an adequate description of the program to assure valve operability as requested by Action Item e of the Bulletin. The program description in your response is little more than a paraphrase of the Bulletin's requirements. Additional information is requested within one month of receipt of this letter.

Responses may be submitted as specified in IE Bulletin 85-03, page 6, i.e.:

"The written reports shall be submitted to the appropriate Regional Administrator under oath or affirmation under provisions of Section 182a, Atomic Energy Act of 1954, as amended. Also, the original copy of the cover letters and a copy of the report shall be transmitted to the U.S. Nuclear Regulatory Commission Document Control Desk, Washington, DC 20555 for reproduction and distribution."

uestions addressing this issue may be forwarded to Richard J. Kiessel, IE 301)492-8119.

Sincerely, Charles E. Norelius, Director Division of Reactor Projects l
