| Title | Failure to Follow Procedure Damages a Centrifugal Charging Pump |
| Description | The inspectors identified a non-cited violation of 10 Part CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to follow procedure during the performance of a surveillance test. Specifically, the licensee failed to ensure applicable prerequisites were met for performing the Unit 1 train A integrated surveillance test procedure by not ensuring component cooling water was properly aligned for operation. This resulted in the overheating and damage to a centrifugal charging pump. The licensee entered the finding into the corrective action program as Condition Report CR-2015-003150. The licensees failure to follow the requirements of Procedure STA-201, Procedure Use and Adherence, to verify all applicable prerequisites were met prior to performing Procedure OPT-430A, Train A Integrated Test Sequence, was a performance deficiency. The performance deficiency was more than minor because it was associated with the human performance attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, operations personnels failure to ensure that component cooling water was properly aligned to the minimum flow line resulted in damage to a centrifugal charging pump. Using Inspection Manual Chapter 0609, Attachment 04, Initial Characterization of Findings, dated June 19, 2012, and Appendix G, Shutdown Operations Significance Determination Process, Attachment 1 Exhibit 3, Mitigating Systems Screening Questions, dated May 9, 2014, the finding was determined to be of very low safety significance (Green) because the finding did not represent a loss of safety function of a single required train, did not degrade level indication, and did not involve external events or fire protection. The finding has a human performance cross-cutting aspect associated with avoiding complacency because the licensee failed to plan for latent issues and inherent risk in performing a major test [H.12]. |
