Docket No. 50-255 LS05-83-0l-020 Mr. David J. VandeWalle Nuclear Licensing Administrator Consumers Power Company 1945 ~J. Parnall Road Jackson, Michigan 49201
Dear Mr. VandeWalle:

SUBJECT:
EVALUATION OF RESPONSE TO IE BULLETIN 80-06 ENGINEERED SAFETY SYSTEM (ESF) RESET CONTROLS We have reviewed your September 14, 1981 response to our request for additional information regarding the subject bulletin.
t*Je find your response unacceptable based on the following:
- 1. Justification was not provided for 3 components (items 16, 19, and 20) in your letter.
- 2.
The intent of IEB 80-06 is that safety-related equipment should remain in its emergency mode upon,r~set of an ESF signal (system-level) and that subsequent operato{_.'action should be required to place an equipment in its normal (non-safety) mode.
We believe 5C,o/
that items 1, 7, 8, 11, 15, 17, 18, 23, 24, and 27 through 31, for
)
'.':hich justification or procedural changes were provided in lieu of (o'I design changes, do not satisfy the intent of 1.EB 80-06.
There oStt u.SW-are two main points in your letter that lead us to this conclusion:
(a)
The procedural changes required that individual valve switches be placed in their emergency positions, if required, prior to ESF reset.
That is, specific operatorevaluat1on and actions are required to keep various safety-related components in their emergency mode of: ESF reset*
(b)
The statement on the bottom of page 2 in Attachment j to your
- letter, 11 *** the:re may be a need to establish the availability of the SWS to the non-critical items in a timely manner",
clearly indicated that ESF reset may be desirable prior to reaching the post-trip conditions of Attachment 2 to your a3011ao3ao S3oii3 -*

Mr. David January 13, 1983 letter.
In this case, some components, for which justification in lieu of design changes was provided, may still be performing safety functions and therefore should not automatically change to the non-safety mode on ESF reset.
It is our position that a system-level reset of *a protecti:ve function should not terminate safety actions which are critical to accident mitigation.
Please respond to these positions 1t1ithin 60 days of the date -of this letter.
Sincerely, Original signed by/
