Licensee-Identified Violation

Description

Technical Specification 3.6.4.2 requires secondary containment isolation Damper 1T42F019to be operable to perform isolation of the secondary containment penetration to prevent release during an accident condition. Contrary to this requirement, on March 19, 2009, Damper 1T42F019 exceeded Surveillance Requirement 3.6.4.2.2, which is performed per the in-service testing program. The licensee staff had changed the preventive maintenance schedule for this damper. This resulted in the damper actuator maintenance due date being moved three years beyond vender recommendations. This contributed to the damper failing its in-service testing requirements. This issue was of very low safety significance since it did not represent an actual open pathway in the physical integrity of the containment system due to the redundant isolation damper in the penetration pathway. This issue was documented in the licensees corrective action program as Condition ReportsCR-GGN-2009-00907 and CR-GGN-2009-01256
