NOTICE OF VIOLATION Pacific Gas 8 Electric Company Diablo Canyon Power Plant Dockets 50-275 and 50-323 Licenses DPR-80 and DPR-82 During an NRC inspection conducted September 16 - 22 and October, 5 - 9,
- 1992, a violation of NRC requirements was identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR 2, Appendix C, the violation is listed below:
Technical Specification 6.8. 1 requires that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide (RG) 1.33, Revision 2, February 1978.
RG 1.33, Appendix A lists, in part, the following procedures:
7.
Procedures for Control of Radioactivity (For limiting materials released to environment and limiting personnel exposure) e.
Radiation Protection Procedures (3)
Airborne Radioactivity Honitoring (4)
Contamination Control Licensee Procedure MRS-2.4.2-GEN 35 (Steam Generator Shot Peening Procedure),
Section 9.7.13.5.2, established September 27, 1992, applied certain rules in order to control airborne radioactivity and contamination.
These rules required that, with ventilation interrupted to the steam generator cold leg for longer than 15 minutes, either:
1.
Shot peening could be temporarily terminated, or 2.
Mith ventilation switched from the cold leg to the hot leg, and dry air supply switched from the hot leg to the cold leg, shot peening could continue.
Contrary to the above, on October 2, 1992, eddy current and shot peening operators failed to implement the provisions for control of radioactivity as given in HRS-2.4.2-GEN 35, Section 9.7.13.5.2, in that ventilation was interrupted to the steam generator cold leg for one
- hour, and shot peening continued without switching of the ventilation and dry air supply as required.
This failure to implement the procedure resulted in the unanticipated spread of airborne radioactivity.
This is a Severity Level IV violation (Supplement IV).
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:
Document Control Desk, Mashington, D.C.
20555, with a copy to the Regional Administrator, Region V, and a copy to the NRC Resident Inspector, within 30 days of the date of the letter transmitting 9212010120 921113 PDR ADOCK 05000275 8
