| Title | Failure to Comply with Technical Specifications Surveillance Requirement 4.0.3 and the Limiting Conditions for Operation for Technical Specifications 3.0.3 |
| Description | The inspectors identified a non-cited violation of Technical Specification (TS) because the licensee did not enter or comply with the technical specification action requirements. Specifically, the licensee did not enter or comply with Technical Specification Surveillance Requirement 4.0.3 upon discovery of a never performed surveillance related to a safety-related relay contact for the Essential Chilled Water system. The licensee discovered the issue on July 27, 2011. However, the licensee did not enter TS 4.0.3 until August 12, 2011. Subsequently, when the licensee entered TS 4.0.3, the licensee did not perform a risk evaluation within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, as directed by the technical specification surveillance requirement. The licensee, per Technical Specification 4.0.3, has up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to perform a risk evaluation or enter the applicable technical specification limiting condition for operation immediately. The inspectors determined that the licensee exceeded the allowed 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and then did not enter the limiting condition for operation for Technical Specification 3.0.3 once the requirements for Technical Specification 4.0.3 and other applicable technical specifications had not been met. The licensee entered this issue into their corrective action program for resolution as CR-WF3-2011-5779. The immediate corrective action included the performance of a special test instruction to demonstrate operability of the safety-related relay. The finding is more than minor because it is associated with the human performance attribute of the Mitigating Systems cornerstone and affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, the inspectors concluded that a failure to comply with TS 4.0.3 and 3.0.3 affects the availability and reliability of the Essential Chill Water system. The inspectors evaluated this finding using NRC Inspection Manual Chapter 0609, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings. The inspectors determined that the finding was of very low safety significance (Green) because the finding was not a design or qualification deficiency, did not represent a loss of a safety function of a system or a single train for greater than its technical specification completion time, and did not screen potentially risk significant due to external events. The finding has a cross-cutting aspect in decision-making component of the human performance area because the licensee did not make a safety-significant or risk-significant decision using a systematic process, especially when faced with uncertain or unexpected plant conditions, to ensure safety is maintained |
