APPENDIX A NOTICE OF VIOLATION  :

Vermont Yankee Nuclear Power Corporation Docket No. 50-271 Vermont Yankee Nuclear Power Station , ,

License No. DPR-28 .

During an NRC inspection conducted on July 3 - August 12, 1990, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and. Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1990), the violation is listed below.

10 CFR 50.59(a) states that changes in the facility as described in the Final Safety Analysis Report (FSAR) may be made without prior Commission -

approval if the proposed change does not involve an unreviewed safety question. _10 CFR 50.59(b) requires a written safety evaluation"which r provides the basis for the determination that the change does not involve an unreviewed safety question, Additionally, Technical Specification.

6.2.6.d states, in part, that the Plant Operations Review Committee (PORC) .

shall' review proposed changes to plant systems which~ would require a t change in normal operating procedures.

Contrary to the above, Vermont Yankee Procedure AP-0155, Revision 13, Current System Valve and Breaker Lineup and Identification, allows changes to the facility to occur prior to the preparation and PORC reviews of written safety evaluations following the implementation of a valve lineup deviation .

from that specified in normal operating procedures. As a result:

l 1. On April 8, 1989, Core Spray Valve'CS-11B was placed in the closed

! position and the required safety evaluation was not prepared and reviewed .

l by PORC until February 21, 1990. FSAR Section 6.4.3 describes that  !

l this valve is normally open to limit the equipment needed to cperate in an accident condition, and  ;

2 On April 21, 1990, High Pressure Core Injection Valve HPCI-19 was '

opened and HPCI-20 was closed and the required safety evaluation was not prepared until April 25 and reviewed by PORC until April 27.

, FSAR Figure 7.4-la describes HPCI-19 as normally closed and HPCI-20 as normally open.

The two examples collectively demonstrate an unacceptable practice of making facility changes as described in the FSAR prior to preparing a written ,

safety evaluation that the change does not constitute an unreviewed safety question.

This is 'a Severity Level IV Violation (Supplement I).
