During an NRC inspection conducted on June 9, to July 27,1997, a violation of NRC requirements was idrntified, in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG 1600, the violation is listed below:
A.
Technical Specification 5.2.2 requires, in part, that written procedures shall be established, implemented and maintained covering the activities referenced in Appendix "A" of Regulatory Guide 1.33, (Rev. 2), dated February 1978. Regulatory Guide 1.33, (Revision 2), dated February 1978, recommends in Appendix "A", Section 3, Procedures for Startup, Operation, and Shutdown of Safety-Related PWR Systems, that instructions for energizing, filling, venting,
- draining, startup, shutdown, and changing modes of operation should be prepared for safety related systems.
- 1. Maine Yankee Procedure OP 1-118, Refueling Water Storage Tank (RWST) Makeup, Recirculation and Purification, stop 6,3.4, requires valve CPU-9 from the Refuel Caviq to be shut, and valve CPU 24 from the RWST to be opened, prior to starting pump P 8, to place the RWST in the " Recirculation Purification Mode."
Contrary to the above, On June 28,1997, an operator incorrectly opened valve CPU-9 instead of CPU 24, to place the RWST in " Recirculation Purification Mode," thereby causing approximately-10,000 gallons of water to be unintentionally diverted from the upender pit to the RWST.
t
- 2. Maine Yankee Procedure 1-17 4, Cavity Draining, Step 6.3.25, requires that valve CPU-2 be opened prior to starting pump P-8, Contrary to the above, on June 26,1997, an operator failed to properly open suction valve, CPU-2, prior to starting pump P-8, causing the pump to trip on low suction pressure.
These two examples are a Severity Level IV violation (Supplement 1).
Pursuant to the provisions of 10 CFR 2.201, Maine Yankee is hereby required to submit a written st:;tement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region I, and a copy to the NRC R:sident inspector at the facility that is the subject of this Notice, within 30 days of the date of the letter i

is not received within the time specified in this Notice, an order or a Demand for information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as 4
may be proper should not be taken. Where good cause is shown, consideration will be given to extending the response time.
