SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)
DOCKET NOS. 50-445 AND 50-446 SMALL BREAK LOCA MODE 4 OPERATIONS SDAR: CP-86-41 (INTERIM REPORT)
Dear Mr. Johnson:
~
On May 28, 1986, we verbally notified your Mr. I. Barnes of a deficiency involving small break LOCA evaluations regarding the effects of the operational status of plant squipment during Mode 4 operations.
This is an p
l interim report of a potentially reportable item under the provisions of 10CFR50.55(e). We have submitted interim reports logged TXX-4876 and TXX-
~
4959, dated June 26, 1986, and August 13, 1986, respectively.
The Westinghouse Owners Group, of which TUGC0 is a member, accepted a program designed by the WOG Analysis Subcommittee to address this concern at their September, 1986 meeting. The projected schedule outlines an April,1987 completion date. Allowing for a reasonable delay time in distributing the conclusions from the subcommittee to all affected parties, we anticipate submitting our next report on this issue by. June 12, 1987.
\\
Very truly yours,
