| Title | Failure to Provide Adequate Maintenance Results in Loss of Core Flow While Shutdown |
| Description | A self-revealing, finding for the licensees failure to provide adequate work instructions for maintenance on the Unit 3 recirculation pump discharge valve motors which included appropriate testing as described in Procedure NPG SPP 06.9.3 Post Modification testing, was a performance deficiency. The performance deficiency was more than minor because it affected the equipment performance attribute of the Initiating Events Cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown operations. The inspector performed the initial significance determination using NRC Inspection Manual Chapter 0609, Appendix G, Attachment 3, Shutdown Operations Significance Determination Process Phase 1 Initial Screening and Characterization of Findings and determined that the finding was of very low safety significance. This finding had a cross-cutting aspect in the area of human performance because the licensee did not ensure that design documentation was correct and that work packages provided the proper tests to ensure the Variable Frequency Drives (VFD) / Recirculation pump trip logic.
