| Title | Failure to control defective component results in safety system surveillance failure |
| Description | A Self-revealing Non-cited violation of Technical Specification requirements was identified for failure to implement procedures to control a defective component and prevent its use in a safety-related system. Specifically, the licensee installed a solenoid valve, known to be defective in the valve actuator for the Unit 3 B emergency containment cooler and the valve subsequently failed a surveillance requirement. The issue was documented in the licensees corrective action program as CR1682798 and corrected by replacing the defective solenoid valve prior to returning the system to service. The failure to identify and control the solenoid valve after having received information that the valve was defective was a performance deficiency. The performance deficiency was determined to be more than minor because it adversely affected the safety related emergency containment cooler system which is used to protect the public from radionuclide releases caused by accidents. The finding was screened using IMC 0609, Significance Determination Process (SDP), Attachment 0609.04 for the Containment Barrier and was screened as of very low safety significance (Green). The inspectors determined that the cross-cutting aspect of Problem Identification and Resolution was affected when the licensee did not identify the defective component in the corrective action program in a timely manner after having received notification from the vendor of a component defect. |
