APPENDIX A NOTICE OF VIOLATION Pacific Gas and Electric Company Diablo Canyon Unit 2 Docket:
50-323 License:
DPR-82 During an NRC inspection conducted from Parch 20 through April 23,
- 1994, a
violation of NRC requirements was identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
10 CFR Part 2, Appendix C, the violation is listed below:
Diablo Canyon Technical Specification 6.8. 1 states, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, dated February 1978.
Appendix A of Regulatory Guide 1.33, Revision 2, recommends procedures for performing maintenance that can affect the performance of safety-related equipment be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances.
1.
Clearance 00044155 was written by the work planning group to be used during the repair of the leak on the Unit 2 reactor coolant system safety injection inlet to Loop 2-3.
The clearance required that Valve SI-2-8809B be closed during the repair of the leak.
Contrary to this requirement, on Harch 31, 1994, while establishing conditions to perform the repair of the leak, the clearance was not followed in that Valve SI-2-8809B was not shut prior to initiating the repair work.
Additionally, an argon purge was connected to the safety injection line without the use of work controls.
The combination of these two occurrences resulted in approximately 50 cubic feet of argon being injected into the reactor coolant system, which could have resulted in elevated reactor coolant system radiation levels.
This is a Severity Level IY violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Pacific Gas and Electric Company is hereby required to submit a written statement or explanation to the U.S.
Nuclear Regulatory Commission, ATTN:
