| Title | Failure to Provide Adequate Limiting Condition for Operation for High River Level |
| Description | The inspectors identified a noncited violation of 10 CFR 50.36(c)(2)(ii)(B) for the failure to include an adequate limiting condition for operation in the technical specification. Specifically, the reactor cannot be placed in a cold shutdown condition using normal operating procedures when the river level exceeds 1009 feet mean sea level, as required by Technical Specification 2.16. This violation has been entered into the licensee‟s corrective action program to determine the appropriate limiting condition for operation. The inspectors determined that the licensee‟s failure to include an adequate limiting condition for operation in the technical specification was a performance deficiency. This finding is more than minor because it affected the protection against external events attribute of the Mitigating Systems Cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences, in that the reactor cannot be placed in a cold shutdown condition using normal operating procedures when the river level exceeds 1009 feet mean sea level. Because this finding occurred while the unit was operating at full power, the inspectors used Inspection Manual Chapter 0609, Appendix A, to determine its significance. Using Attachment 1 of that appendix, the inspectors determined that this finding had very low risk significance because the finding did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event, using the criteria included in Exhibit 1 of Inspection Manual Chapter 0609 Attachment 4. Since the finding is not indicative of current licensee performance, there is no crosscutting area assigned to this finding. |
