ENCLOSURE 1 NOTICE OF VIOLATION System Energy Resources, Inc.

Docket No. 50-416 Grand Gulf License No. NPF-29 During the Nuclear Regulatory Commission (NRC) inspection conducted on December 19, 1987 - January 15, 1988 a violation of NRC recuirements was identified.

Technical Specification 4.5.1.c.2.(b) requires at least once per 18 months a channel calibration be performed on Emergency Cooling System (ECCS) header delta pressure instrumentation and verification that the setpoint of the High Pressure Core Spray (HPCS) system, Low Pressure Core Spray (LPCS) system and Low Pressure Coolant Injection (LPCI) subsystems to be

1. 2 0.1 psid change from the normal indicated differential pressure.

Contrary to the above, as of January 14, 1988, the normal indicated differential pressure for the LPCS and LPCI systems had not been determined and ECCS header delta pressure instrumentation had been verified to be 1.210.1 psid from a calulated differential pressure instead of the normal indicated differential pressure.

This is a Severity Level V violation (Supplement I).

Pursuant to the provisions of 10 CFR 2.201, System Energy Resources, Inc. is hereby required to submit a written statement or explanation to the Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington, DC 20555, with a copy to the Regional Administrator, Region II, and a copy to the NRC Resident Inspector, Grand Gulf, within 30 days of the date of the letter transmittingthisNotice.
