l ENCLOSUREI NOTICE OF VIOLATION l
Northeast Nuclear Energy Company Docket Nos. 50-245; 50-336 l
Millstone Nuclear Power Station License Nos. DPR-21; DPR-65 Units 1 and 2 During an NRC inspection conducted on March 3,1993 through April 3,1993, violations of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violations are listed below:
I A.
10 CFR Part 50, Appendix B, Criterion XVI (Corrective Actions) requires, in part, that measures shall be established to assure that conditions adverse to quality, such as failures, deficiencies and deviations be promptly identified and corrected. The measures shall assure that the cause of the condition is determined and corrective action is taken to preclude recurrence.
Contrary to the above, since 1985, fourteen safety-related auxiliary electrical contacts have failed to operate on demand, rendering Unit 1 equipment inoperable. The cause of the failures was attributed to dried grease / cleaner residue, a maintenance related l
condition applicable to many similar safety-related contacts. The licensee did not l
develop effective corrective actions to preclude recurrence of the subsequent failures.
1 l
l This is a Severity Level IV Violation (Supplement I).
B.
Millstone Unit 2 Technical Specification 6.8.1.a. requires that procedures be established, implemented, and maintained as recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978. Regulatory Guide 1.33 recommends procedures for administrative control of surveillance testing.
Surveillance Procedure SP-2401C, "RPS Turbine less of Imad Test," step 6.2.1 requires that certain reactor protection system (RPS) trip bistables be bypassed prior to testing the turbine trip bistable. Step 6.2.6 requires alarms on the nuclear l
instrumentation linear power range channel drawer and the RPS trip bistables to be reset prior to removing the bypass keys installed in step 6.2.1.
i Contrary to the above, on February 22,1993, on one occasion, step 6.2.6 of l
SP-2401C was not preformed prior to removing the bypass keys; and, on two occasions, Step 6.2.1 of SP-2401C was not performed prior to testing the turbine trip bistables.
This is a Severity Level IV Violation. (Supplement I).

C.
Millstone Unit 2 Technical Speciiication 6.8.1.e. requires that procedures be established, implemented, and maintained for emergency plan implementation.
Emergency Plan Implementing Procedure 4701-4, " Event Classification," requires prompt NRC notification of any event or condition that results in an unplanned automatic actuation of any engineered safety feature, including the reactor protection system (RPS).
l l
Contrary to the above, on February 22,1993, an unplanned automatic actuation of the RPS system occurred due to excessive feeding of the steam generators; the licensee did not report the event to the NRC until March 11, 1993.
l This is a Severity Level IV Violation. (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Northeast Nuclear Energy Company is hereby l
required to submit a written statement or explanation to the U.S. Nuclear Regulatory l
Commission, A*ITN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region I, and if applicable, a copy to the NRC Resident Inspector within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly marked as a " Reply to a Notice of Violation" and should include for l
each violation: (1) the reason for the violation, or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to avoid funher violations, and (4) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending the response time.
