NOTICE OF VIOLATION Pacific Gas and Electric Company Diablo Canyon Nuclear Power Plant Docket No. 50-323 License No.
DPR-82 During an NRC inspection conducted on March 11 through April 21, 1990, 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 (1990),-the violation is listed below:
A.
Technical Specification 3.9. 12 specifies that two Fuel Handling Building Ventilation Systems shall be operable.
Action statement
- b. states, "Mith no Fuel Handling Building Ventilation Systems
- operable, suspend all operation involving movement of fuel within the spent fuel pool or crane operation with loads over the spent fuel pool..."
Contrary to the above, between March 12 and March 15, 1990, no Unit 2 Fuel Handling Building Ventilation Systems were operable and operations involving movement of fuel within the spent fuel pool and crane operation with loads over the spent fuel pool were conducted.
The Fuel Handling Building Ventilation System (FHBVS) was not operable in that it could not perform its specified function to maintain a negative pressure greater than or equal to 1/8 inch Mater Gauge relative to the outside atmosphere because two FHBVS barrier doors had been erroneously blocked open.
Licensee test results showed that only 1/16 inch water gauge of negative pressure could be maintained.
This is a Severity Level IV violation, applicable to Unit 2 (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.

Consideration may be given to extending the response time for good cause shown.
