| Title | Ineffective Corrective Action Results in Inoperable Component Cooling Water Heat Exchanger |
| Description | A self-revealing Green NCV of Title 10 of the Code of Federal Regulations (10CFR) Part 50, Appendix B, Criterion XVI, Corrective Action, was identified in that FENOC failed to prevent further degradation of the A component cooling water heat exchanger, which was a significant condition adverse to quality. Inspectors determined that the unhindered rate of heat exchanger tube corrosion was a performance deficiency that was within FENOCs ability to foresee and correct. FENOC entered this issue into their corrective action program for further resolution as condition report (CR) 2012-13945. This finding is more than minor because it affects the Mitigating Systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors determined this finding was not a design qualification deficiency resulting in a loss of functionality or operability, did not represent an actual loss of safety function of a system or train of equipment, was not potentially risk-significant due to a seismic, fire, flooding, or severe weather initiating event, did not affect reactivity control systems, and did not involve the fire brigade. Therefore, inspectors determined the finding to be of very low safety significance. This finding has a cross-cutting aspect in the area of Human Performance, Resources, in that FENOC failed to ensure adequate design margin of the A component cooling water heat exchanger was maintained, and to correct the long-standing issue of leakage past the A component cooling water heat exchanger isolation valves |
