2 ENCLOSURE 1 NOTICE OF VIOLATION Public Service Company of New Hampshire Docket No.

50-443 Seabrook Unit 1 License No. NPF-86 During NRC inspection from April 10 - May 13, 1990, a violation of NRC_ require-ments was identified in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR, Part 2, Appendix C.

That violation is listed below:

Technical Specification 6.7.1.a requires that the procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978, be established and implemented.

Regulatory Guide 1.33, Revision 2, February 1978, Appendix A specifies procedures for energizing, startup, operation, shutdown, and changing modes of operation of PWR (pressurized water reac-tor) main steam systems (Section 3.1), for PWR stack and ventilation air monitoring (Section 7.c), and for maintenance that can affect the perform-ance of safety-related equipment (Section 9.a).

Contrary to the above, as of April 3, 1990, no procedure had been estab-lished for operation of an isolation valve for turbine first stage pres-sure instrument PT-506, which provides an input signal to the Reactor Protection System. Closure of the isolation valve rendered PT-506 inoper-able when its operability was required.

Contrary _ to the above, as of January 1,1990, no procedure had been estab-lished covering the required position for purge isolation valves for the wide range gas monitor in the station ventilation stack system.

Misposi-tioned purge isolation valves rendered the monitor inoperable when it was required to be operable.

Contrary to the above, about April 4,1990, improper implementation of procedure steps for restoring the main turbine to proper operating line-up af ter maintenance resulted in a turbine trip during turbine startup.

This is a Severity Level IV violation (Supplement 1).

Pursuant to 10 CFR 2.201, the Public Service Company of New Hampshire is hereby required to submit to this office, within 30 days of the date of the letter transmitting this Notice, a written reply including:

(1) the reason for the violation, if admitted; (2) the corrective steps which have been taken and the results achieved; (3) the corrective steps which will be taken to avoid further violations; and (4) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending this response time.

l The reply required by this Notice is exempt from the Office of Management and Budget clearance required by the Paperwork Reduction Act of 1989, PL 96-511.
