Title | Failure to Timely Enter Technical Specification Surveillance Requirement 3.0.1 |
Description | The inspectors identified a non-cited violation of Technical Specification Surveillance Requirement 3.0.1, for the failure to follow requirements when a surveillance was not performed within the specified frequency and declare the Limiting Condition for Operation not met or follow the provisions in Surveillance Requirement 3.0.3. Specifically, the licensee did not follow Technical Specification Surveillance Requirement 3.0.1, when they discovered that Surveillance Requirement 3.8.1.9 was not performed within its specified frequency and either declare Technical Specification Limiting Condition for Operation 3.8.1 not met, or perform the required actions to determine whether compliance with the requirement to declare the Limiting Condition for Operation not met may be delayed. The licensee failed to enter Technical Specification Surveillance Requirement 3.0.1, until September 29, 2015, after discussions with the NRC. On September 29, 2015, the licensee adequately performed the actions required in Technical Surveillance Requirement 3.0.3. The licensee entered this issue into their corrective action program as Condition Report CR-GGN-2015-5602. The failure to timely enter and perform the actions as required per Technical Specification Surveillance Requirement 3.0.1 was a performance deficiency. This performance deficiency is more than minor, and therefore a finding, because it is associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to perform technical specification surveillance requirements, and associated actions, did not ensure that the diesel generator could appropriately respond to initiating events. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, and Inspection Manual Chapter 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the inspectors determined that the finding is of very low safety significance (Green) because it: (1) was not a deficiency affecting the design or qualification of a mitigating structure, system, or component, and did not result in a loss of functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than their technical specification allowed outage time; and (4) did not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety significant in accordance with the licensees maintenance rule program. The inspectors determined that the finding has a conservative bias cross-cutting aspect within the human performance area because the licensee failed to use decision makingpractices that emphasize prudent choices over those that are simply allowable. Specifically, operations personnel failed to enter Technical Specification Surveillance Requirement 3.0.1 because the operability determination alone justified operability without doing a detailed risk evaluation [H.14]. |
