Docket No. 50-155

N MS David P. Hoffman Nuclear Licensing Administrator Consumers Power onpany c
212 West Michigan Avenue Jackson, Michigan 49201 Deir Mr. Hoffman:
I Sy letter dated February 23, 1980, you were requested to provide information regarding primary coolant system pressure isolation valves.
The objective of this 10 CFR 50.54(f) letter was to identify those plants which have either or both of the valve configurations found in WASH-1400 (Event V) to be significant risk contributors to an intersystem LOCA which results in a core melt accident.
We have confirmed that the two specific Event V valve configurations do not exist at your facility. This is based upon the evaluation of your response to our February letter as well as the review of previously docketed information (Enclosure). Based on this, our activities regarding these valve configurations have been finalized for your f acility.
l In addition to these Cvent V valve configurations, we are continuing our efforts to review cther configurations located at high pressure /
low pressure system boundaries for their potential risk contribution to an intersystem LOCA which may result in a core melt accident.
Therefore, further activity regarding the broader topic of intersystem LOCA's may be expected in the future.
Your time and effort in closing out the Event V portion of the inter-system LOCA concern are appreciated.
Sincerely, lddK.4.b~
Dennis M. Crutchfield, Chief
