i ENCLOSURE 1
NOTICE OF VIOLATION Pacific Gas and Electric Company Diablo Canyon Nuclear Power Plant Docket:
50-323 License:
DPR-82 During an NRC inspection conducted on April 14,
- 1996, through May 25,
- 1996, two violations of NRC requirements were identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
NUREG-1600, the violations are listed below:
1.
- states, in part, that the holder of a license authorizing operation of a production or utilization facility may make changes in the facility as described in the safety analysis report....
10 CFR 50.59(b)(l) states, in part, that the licensee shall maintain records of changes in the facility... to the extent that these changes constitute changes in the facility as described in the safety analysis report....
These records must include a written safety evaluation which provides the bases for the determination that the change...
does not involve an unreviewed safety question.
Diablo Canyon Updated Final Safety Analysis Report, Section
- 9. 1.3.2. 1. 1 describes the spent fuel pool cooling pumps.
Section 8.3 describes the power supplies to the pumps as being Class 1E, vital power.
Contrary to the above, on April 16, 1996, the inspector identified that a temporary jumper was installed to supply non-vital power to spent fuel pool cooling pump 2-1, without having performed a safety evaluation.
The jumper was installed in accordance with an equipment control guideline (ECG) for the spent fuel pool cooling pumps;
- however, the acceptability of the deviation from the licensee's safety analysis report was not documented in a safety evaluation.
This is a Severity Level IV violation (Supplement I).
2.
Diablo Canyon Technical Specification 3.9. 12, states that two fuel handling building ventilation systems shall be operable whenever irradiated fuel is in the spent fuel pool.
With one fuel handling building ventilation system inoperable, fuel movement within the spent fuel pool, or crane operation with loads over the spent fuel pool, may proceed provided the operable fuel handling building ventilation system is capable of being powered from an operable emergency power source.
Contrary to the above, on April 20,
- 1996, between approximately 11: 11 am and 1:42 pm, loads were moved over the spent fuel pool when the operable fuel handling building ventilation system was not capable of being powered automatically from an operable emergency power source.
Licensee personnel opened the emergency power supply breaker to the system and inappropriately relied on manual actions to align an emergency power source if needed.
This is a Severity Level IV violation (Supplement I).

r 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, Washington, D.C.
20555 with a copy to the Regional Administrator, Region IV, 611 Ryan Plaza Drive, Suite 400, Arlington, Texas
- 76011, and a copy to the NRC Resident Inspector at the facility that is the subject of this Notice, 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 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 further violations, and (4) the date when full compliance will be achieved.
Your response may reference or include previous docketed correspondence, if the correspondence adequately addresses the required response.
If an adequate reply is not received within the time specified in this Notice, an order or a Demand for Information may be issued as to why the license should not be modified, suspended, or revoke'd, or why such other action as may be proper should not be taken.
Where good cause is shown, consideration will be given to extending the response time.
Because the response will be placed in the NRC Public Document Room (PDR), to the extent possible, it should not include any personal privacy, proprietary, or safeguards information so that it can be placed in the PDR without redaction.
However, if it is necessary to include such information, it should clearly indicate the specific information that should not be placed in the
- PDR, and provide the legal basis to support the request for withholding the information from the public.
