ed NOTICE OF VIOLATION Commonwealth Edison Company Docket No. 50-295 As a result of the inspection conducted on July 31 through September 3,1987, and in accordance with 10'CFR Part 2, Appendix C - General Statement of Policy and Procedure for NRC Enforcement Actions (1985), the following violation was identified:

Technical Specification 4.8.3 requires that when the reactor is in Modes 1 or 2 (power operation or hot standby, respectively) and one of the two residual heat removal pump systems is inoperable, then the remaining residual heat removal system, both centrifugal charging pump systems, and both safety injection pump systems, including the standby AC and DC power supplies, shall be demonstrated to be operable immediately and daily thereafter.

Contrary to the above, on August 20, 1987, while Unit I was in Mode 1, one of the two residual heat removal pump systems became inoperable, in that during safeguards testing valve 1 MOV-RH 8700B failed to stroke open on a safety injection signal as designed, but the remaining residual heat removal system, both centrifugal charging pump systems, and both safety injection pump systems, including the standby AC and DC power supplies, were not demonstrated i to be operable until August 26, 1987.

This is a Severity Level IV violation. (Supplement 1)(295/87017-03)(DRP)).

Pursuant to the provisions of 10 CFR 2.201, you are required to submit to this office within thirty days of the date of this Notice a written statement or explanation in reply, including: (1) corrective action taken and the results achieved; (2) corrective action to be taken to avoid further violations; and (3) the date when full compliance will be achieved. Consideration may be given to extending your response time for good cause shown.
