| Title | Failure to Maintain an Adequate TSC to Support Emergency Response |
| Description | The inspectors identified an AV of 10 CFR 50.54(q) for the licensees failure to provide a defensible technical basis for unfiltered air in-leakage, supported by sufficient experimental and empirical data for an input to a calculation used as the basis for TSC functionality. The compensatory measure established on February 16, 2012, was to issue a standing order (12-005) related to habitability and relocation of the TSC. The licensee has submitted an event notification (EN 47655), and entered this issue into their CAP as NCR 516120. The licensees failure to provide a defensible technical basis supported by sufficient experimental and empirical data for an input to the Alternate Source Term (AST) calculation, which was the basis for TSC functionality, was a performance deficiency. This failure resulted in the licensee being unable to meet the TSC habitability requirements as specified in the Harris Emergency Plan, PLP-201, Revision 57, section 3.3.1. The finding was more than minor because it affected the Emergency Preparedness Cornerstone objective of ensuring that the licensee was capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. Specifically, the ERO performance attribute was affected during the times when the TSC was not functional, and it did not meet 10 CFR 50.47(b)(8) Planning Standard program elements. The finding was assessed for significance in accordance with NRC IMC 0609, Appendix B, Emergency Preparedness Significance Determination Process. Attachment 2 of Appendix B, Failure to Comply Significance Logic is as follows: Failure to comply; Loss of Risk Significant Planning Standard Function (RSPS), NO; RSPS Degraded Function, NO; Loss of Planning Standard Function, YES; results in a White finding. The inspectors determined that this resulted in a preliminarily low to moderate safety significance finding (White). The inspectors did not identify a cross-cutting aspect associated with this finding because the performance deficiency occurred in 2001 and does not represent current licensee performance. |
