ENCLOSURE 1
NOTICE OF VIOLATION Pacific Gas and Electric Company Diablo Canyon Nuclear Power P'lant Docket:
50-323 License:
DPR-82 During an NRC inspection conducted on January 21,
- 1996, through March 2,
- 1996, three violations of NRC requirements were identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
(60 FR 34381; June 30, 1995),
the violations are listed below:
A.
Diablo Canyon Technical Specification 6.8. l.a requires procedures to be established, implemented and maintained as recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Appendix A of Regulatory Guide 1.33 requires procedures to be written for each surveillance test, inspection, or calibration listed in the licensee's Technical Specifications.
Technical Specification 4.3.3.6 requires a monthly channel check to be performed on accident monitoring instrumentation, including incore thermocouples.
Contrary to the above, on February 29, 1996, it was determined that Surveillance Test Procedure (STP) 1-1D, Revision 25A, Monthly Checks Required By Licenses, the procedure established by the licensee to fulfill the Technical Specification required monthly channel check of the incore thermocouples, did not meet the requirements of Technical Specification 4.3.3.6.
Specifically, the procedure failed to require operators to visually observe and evaluate the incore thermocouple indications provided locally at the instrument.
This is a Severity Level IV violation (Supplement 1).
B.
Diablo Canyon Technical Specification 6.8. 1.a requires procedures to be established, implemented, and maintained covering t'"e Fire Protection Program.
.Procedure Tgl.DC12, Revisi'on 1, "Fir~rigade Training," requires a
biennial review of tho, subject matter contained in the initial fire brigade member and leader training courses.
Contrary to the above.
none of the personnel assigned to the fire brigade 7 p.m. to 7 a.m. shift watch on December 29.
- 1995, had completed the biennial training requirements.
This is a Severity Level IV violation (Supplement 1).
10 CFR Part

Contrary to the above, between September 15,
- 1994, and January 15,
- 1996, a condition adverse to quality existed that was not promptly identified or corrected.
Specifically, the licensee discovered that closing the centrifugal charging pumps common recirculation flow path isolation valves during periodic pump performance tests potentially impacted the operability of both charging pumps.
The licensee failed to consider the effect of closing the valves on accident analyses For over 1 year after the initial concerns were identified.
Failure to take prompt and comprehensive corrective actions resulted in both units being unnecessarily placed in an unanalyzed condition for a short period during the performance of periodic centrifugal charging pump surveillance testing.
This is a Severity Level IV violation (Supplement 1).
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:
