I During an NRC inspection conducted April 16 through May 31, 1989, two violations of NRC requirements were identified. The first violation involved two examples of a failure to follow a safety procedure and an inoperable reactivity control system. The :;econd violation involved a failure to have Squib Valve A operable for a period of about 1 year in violation of plant technical specifications. In accordance with the " General Statement of Polic Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (y and1988),the violations are listed below:

A. Failure to Follow a Safety Procedure 10 CFR Part 50, Appendix B, Criterion V, states, in part, that

" Activities affecting quality shall be prescribed by documented instructions procedures or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings."

CNS Procedure 0.9, " Equipment Clearance and Release Orders," Revision 7, dated February 23, 1989, specifies that the clearance order procedure provide a means of safely isolating equipment for repairs.

Contrary to the above, on May 18, 1989, the NRC inspector found Main Steam Line Drain Outboard Isolation Valve MS-M0-77 shut while danger-tagged open by Clearance Order 89-442. In additica, Clearance Order 89-827 utilized one tag to isolate seven valves for performance of maintenance.

This is a Severity Level IV violation. (Supplements)(298/8918-01)

B. Inoperable Reactivity Control System Technical Specifications 3.4.b.1 allows continued operation for only 7 days when a redundant component in the standby liquid control system is inoperabic.

Contrary to the above, the Squib Vahe A, a redundant component, was made inoperable on May 15, 1988, and remained inoperable until May of 1989.  !

The reactor operated in all Modes during that period.

This is a Severity Level IV violation. (Supplements)(298/8918-02) 8907070068 PDR 890622ADOCK PDC 05000298 Q
