| Title | Failure to Implement Monitoring Plan for Permanent Flood Mode Structures |
| Description | The NRC identified a finding for the licensees failure to incorporate fleet inspection monitoring requirements for permanent flood mode structures into the Watts Bar external flood protection program procedure. Specifically, Watts Bar procedure 0-TI-444, External Flood Protection Program, Revision 0, failed to detail the procedures and processes used to track, trend, and maintain key program data related to periodic inspections for permanent flood mode structures. The licensee generated Problem Evaluation Reports (PERs) 824744 and 823305 to address this issue and other observations regarding the Watts Bar flood monitoring plan. The performance deficiency was more than minor because if left uncorrected it would lead to a more significant safety concern. Specifically, the absence of a site-level monitoring plan in 0-TI- 444 to track periodic inspection results of permanent flood mode structures would degrade the licensees ability to detect and correct declining external flood hazard barrier conditions or performance to ensure Watts Bar remained capable of withstanding a probable maximum flood elevation as intended by the external flood protection program. The inspectors concluded the finding was associated with the mitigating systems cornerstone and determined the finding was of very low safety significance (green) because the finding had not resulted in an actual physical degradation of equipment or function specifically designed to mitigate a seismic, flooding, or severe weather initiating event. The inspectors concluded the cause of the finding was related to the complete, accurate, and up-to-date procedures cross-cutting aspect in the Resources component of the Human Performance area. Specifically, the licensees implementation of the fleet external flood protection program had not ensured that site procedures and other resources were available to provide complete, accurate, and up-to-date documentation and procedures regarding the treatment of passive flood barriers. |
