ENCLOSURE 1 NOTICE OF VIOLATION North Atlantic Energy Service Corporation Docket No. 50-443 Seabrook Station, Unit 1 Licensee No. NPF-86 During an NRC inspection conducted durirg the period August 16 through October 4, 1997, a violation of NRC requirements was identified. in accordance with the " General Statement of Policy and Procedures for NRC Enforcement Actions," NUREG 1600, the violation is listed below.

Technical Specification 6.7.1.a states, in part, that writton procedures shall be implemented as recommended in Appendix A of Regulatory Guide (RG) 1.33. RG 1.33 states that procedures should be implemented to control maintenance activities.

Contrary to the above, procedures were not implemented as noted below.

A. Procedure IN1640.910,MDT-20 SG Feed Pump A Speed Control Calibration, step 8.9.1 required that the lifting of an electricallead (D4) be documented.

On September 18,1997,I&C technicians performing troubleshooting activities on the "A' main feed pump ddFP), lif ted electricallead (D4) without documenting this action as required. This resutted in the MFP being reassembled and tested without terminating lead (D4), defeating the electrical trip capability of the MFP.

B. Maintenance Procedure MA 3.0, Work Practices required that design engineering ovaluate replacement parts that look different from the originally installed part.

During refueling outage five. the nitrogen fill line check valves (NG-V22 and NG V24) to the "C" and "D" safety injection accumulators were reassembled with incorrect springs that had not been evaluated by design engineering.

The NG V22 valve then failed to operate while attempting to charge the "C" safety injection accumulator.
