| Title | Entry into a non-conservative technical specification with both isolation condensers inoperable during power operation. |
| Description | The inspectors identified a Green NCV of Technical Specification 3.8.D, Isolation Condenser, when Exelon did not enter the correct technical specification and take the required actions when both isolation condensers were made inoperable in order to perform corrective maintenance. Specifically, Exelon incorrectly entered general Technical Specification 3.0.A for conditions in excess of those addressed in the technical specifications instead of the more specific technical specification (3.8.D) for when both isolation condensers are inoperable. Entry into the appropriate technical specification would have required the initiation of an immediate shutdown instead of allowing 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> to reach cold shutdown. Exelon entered this issue into their corrective action program as IR 1386020 to track resolution of this issue. The inspectors determined that not entering the correct technical specification and invoking the associated action requirement was a performance deficiency that was reasonably within Exelon\'s ability to foresee and correct, and should have been prevented. This finding is more than minor because it is similar to example 2.a in IMC 0612, Appendix E. Specifically, by not entering TS 3.8.D, Exelon did not meet the technical specification requirement to start shutting down the plant immediately when both isolation condensers were made inoperable. Additionally, this finding also affects the Mitigating Systems cornerstone objective of ensuring 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, and was not potentially risk-significant due to a seismic, fire, flooding, or severe weather initiating event. Therefore, inspectors determined the finding to be of very low safety significance (Green). This finding has a cross-cutting aspect in the area of Human Performance, Resources, because Exelon\'s training of personnel not sufficient to preclude entry into a nonconservative technical specification. |
