NOTICE OF VIOLATION (NRC INSPECTION REPORT NO. 50-458/93-09)
This is in reference to the inspection conducted March 29 through April 22, 1993, of the fire protection program at the River Bend Station nuclear pow u plant, St. Francisville, Louisiana.
A report documenting the results of this inspection was issued on May 24, 1993.
On June 4,1993, you and other Gulf
'
States Utilities (GSU) representatives attended an enforcement conference in the NRC's Arlington, Texas office to discuss NRC's preliminary conclusion that a potentially significant violation of NRC requirements had occurred.
The violation in the enclosed Notice of Violation involves a failure to meet the requirements of 10 CFR 50, Appendix B, Criterion XVI, which requires, in part, that GSU have measures in place to assure that conditions adverse to quality, such as deficiencies, are promptly identified and corrected.
In this case, GSU did not promptly identify and correct a deficiency in the River Bend Station fire hazards analysis (FHA).
The deficiency involved GSU's failure to complete an associated circuit analysis for common enclosures and to provide the basis for, or detailed analyses to support, certain conclusions relative to the ability to safely shut down the River Bend Station facility in the event of a design basis fire.
As discussed at the enforcement conference, this violation is of concern because GSU committed in response to a related Notice of Violation issued on April 6,1990, that a final review and verification of the FHA would be performed by an independent contractor and that the contractor was to provide fully detailed documentation of the design bases and assumptions of the FHA.
The NRC's inspection determined that all associated circuit analyses had not been performed and that little documentation was available to support certain assumptions of the FHA, particularly assumptions that the electrical control circuits necessary to assure a safe facility shutdown in the event of a fire would not be adversely affected by certain associated circuits.
During the enforcement conference, GSU stated that its fire protection program assures the safety of the facility through defense in depth -- fire prevention, fire detection and suppression, and the performance of essential plant functions. GSU stated that the NRC-identified deficiency in FHA supporting documentation is limited to low-voltage control circuits and that dg

GSU also noted that, with the exception of the drywell and main steam tunnel, all safety-related areas of the plant have been covered by fire watches for several years.
'
The ultimate safety significance of this violation cannot be determined at this time.
Neither GSU nor the NRC can know at this time whether the detailed'
analyses that GSU is now committed to complete by October 29,.1993, will reveal any actual deficiencies in the design of electrical control circuits.
Based on the information available at this time, which indicates only that the FHA documentation is deficient, this violation has been classified at Severity Level IV in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (Enforcement Policy).
The NRC will review separately any findings of deficiencies that indicate an-actual degradation of plant safety and will determine at that time whether enforcement action or other regulatory action is appropriate. Whether additional enforcement action is necessary will depend on the aggressiveness of your corrective actions and the scope and significance of any adverse find:ngs.
You are required to respond to this letter'and should follow the instructions specified in the enclosed hulice when preparing your response.
In your response, you should document the specific actions taken and any additional actions you plan to prevent recurrence.
After-reviewing your response to this Notice, including your proposed corrective actions and the results of future inspections, the NRC will determine whether further NRC enforcement action is necessary to ensure compliance with NRC regulatory requirements.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and its enclosure will be placed i1 the NRC Public Document Room.
The responses directed by'this letter and the enclosed Notice are not subject to the' clearance procedures of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, Pub. L. No.96-511.
Sincerely,
