RESPONSE TO NOTICE OF VIOLATION STATEMEN"r' OF VIOLATION:

Technical Specification 6.2.A.1 required written procedures be established and implemented for applicable pmcedures in Regulatory Guide 1.33, Rev. 2, Appendix A. Regulatory Guide 1.33 Paragraph 1.c. lists Equipment Control procedures (e.g., locking and tagging).

Licensee prowfure QCAP 230-4, " Equipment Out of Service," Rev.14, Step D.l.f.l.(c) required OOS reviewers review OOS activities to ensure operational concerns associated with the activity are identified.

1 t

a.

The OOS reviewers documented the shared diesel generator would be operable to Unit 2 for OOS numbers 19190,19698,18862 and 19187.

Contrary to the above, on Febmary 29,1996, initiation of OOS numbers 19190,19698,18862 and 19187 rendemd the shared diesel generator inoperable to Unit 2. An operational concern associated with the activity was not identified.

4 Licensee pmcedure QCAP 230-4, " Equipment Out of Service," Rev.14, Step D.I.g.2 required unit supervisors review OOS activities to ensure plant conditions are correct to support the activity.

b.

The unit supervisor initiated OOS Number 19285 which required Unit 1 Primary containment isolation system, train "B" be operable.

Contrary to the above, on March 15, 1996, the unit supervisor initiated OOS Number 19285 with Unit 1 primary containment isolation system train "B" inoperable. A condition not correct to support the activity.

REASON FOR VIOLATION:

The primary cause of this violation was personnel error. In the first example, the preparer and reviewer of the out of service documentation both failed to identify all affected portions of the electrical circuit that was being de-energized. As a msult, the individuals both failed to identify the total affect on the 1/2 Diesel Generator automatic start function. In the second instance, the Unit Supervisor and the Nuclear Station Operator verified Reactor Pmtection System irlays instead of the appropriate Group II isolation logic relays to ensure that an automatic actuation would not occur.

4 RESPONSE TO NOTICE OF VIOLATION CORRECTIVE ACTIONS TAKEN:

Appropriate disciplinary action was administered to the personnel involved in these events.

ACTIONS TO PREVENT FURTIIER OCCURRENCE:

Selected diesel generator procedun:s have been revised to include limitations and actions describing the impact of removing the fuses for the 1/2 diesel generator automatic start relay.

These events have been presented to all licensed operators during licensed operator retraining.

]

DATE WIIEN FULL COMPLIANCE WILL BE MET:

For item (a) above, compliance was met on March 4,1996, following installation of the 1/2 Diesel Generator automatic start relay fuse. For item (b) above, compliance was met on March 15,1996, following re-energization of RPS A and restoration of reactor building ventilation.
