Title | City Water Tank Below Required Level Due to Inadequate Design Change Implementation |
Description | The inspectors identified a non-cited violation of Technical Specification 5.4.1, Procedures, when Entergy did not implement on-line leak repair procedures to repair a steam leak on valve MS-2A. Specifically, Entergy performed multiple leak sealant injections on valve MS-2A without engineering controls described in station on-line leak repair procedures. Corrective actions planned included reviewing this issue with the planning and component engineering departments and determining if training on the online leak sealing procedures is warranted. The finding was more than minor because, if left uncorrected, inadequate control of leaksealant injections would become a more significant safety concern. The inspectors determined the significance of the finding using Inspection Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings. The finding was determined to be of very low safety significance (Green) because it did not represent a loss of system safety function. Specifically, Entergys operability evaluation concluded that the sealant that was injected extruded back out of the leak path and likely did not reach the valves seat or hinge. The finding had a cross cutting aspect related to work control in the area of Human Performance. Entergy personnel did not appropriately plan work activities to conduct online leak repairs on a safety related component. Specifically, Entergy did not identify necessary engineering procedures to adequately perform leak seal repairs on MS-2A during the planning process. These procedures provide necessary limitations, contingencies, and abort criteria. (H.3.(a)) (Section 1R18) |
