Title | Failure to Enter Correct Technical Specification Action Statements When Authorizing Work |
Description | The inspectors identified a non-cited violation of Technical Specification, 5.4.1.a, Procedures, for the failure to follow Procedure OI-09, Operations Standards and Expectations, Revision 56, when authorizing work on emergency core cooling system boundary components. Specifically, the licensee failed to understand the technical specification impact when performing emergency core cooling system venting activities. Upon identification of this deficiency, the licensee issued Night Order 1419 documenting the requirement to declare the emergency core cooling systems inoperable while performing technical specification required fill and vents. The licensee entered this issue into the corrective action program as Action Request 272948. This performance deficiency was more than minor because it adversely affected the configuration control attribute of the Mitigating Systems Cornerstone objective of ensuring the capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, the inspectors determined the finding was of very low safety significance because the finding did not represent a loss of safety function, did not represent an actual loss of function of a single train for greater than its technical specification allowed outage time, did not represent an actual loss of function of one or more non-technical specification equipment for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The inspectors determined the finding had a cross-cutting aspect in the area of human performance associated with the decision making component because the licensee failed to verify the validity of the underlying assumption that the emergency core cooling system was operable while performing venting operations. |
