| Title | Materially Inaccurate Information Provided to NRC Regarding SSF Event Mitigation Capability |
| Description | A licensee-identified apparent violation of 10 CFR 50.9(a) was identified when it was determined that information contained in the Oconee Nuclear Station SSF RC Letdown Action Plan was inaccurate. This information, combined with an evaluation that showed RCS letdown flow rates on Unit 2 and Unit 3 were greater than the flow rate required for pressurizer level control during the last surveillance test, was used by the NRC in the review which allowed both units to remain at power until the next forced or refueling outage. This violation has been entered into the corrective action program as PIP O-10-0561.The failure to provide complete and accurate information impacted the regulatory process in that the inaccurate information was material to NRCs determination there was sufficient justification to allow both units to remain in operation until the next forced or refueling outage before removing the filter. This violation is more than minor in that additional inspection would have resulted had the information been accurate when reviewed by the inspectors. The inspectors reviewed Supplement VII of the Enforcement Policy and determined the severity level of this violation is potentially greater than Severity Level IV. Cross-cutting aspects are not assigned to violations being dispositioned through the traditional enforcement process. |
