Title | Failure to Declare Secondary Containment Inoperable Based on Failed Surveillance Testing |
Description | The team identified a non-cited violation of Technical Specification 3.6.4.1 Condition A, for the failure to declare secondary containment inoperable. Specifically, on August 1, 2015, the licensee failed to declare secondary containment inoperable after it failed to achieve the necessary vacuum to pass Surveillance Requirement 3.6.4.1.4. The licensee entered this issue into their corrective action program as Condition Report CR-GGN-2015-05826. The failure to declare secondary containment inoperable due to failed surveillance test and enter the appropriate action statements as required by the licensees technical specifications is a performance deficiency. This deficiency is more than minor, and therefore a finding, because it is associated with the Structures, Systems, Components, and Barrier Performance attribute of the Barrier Integrity cornerstone. Specifically, the failure to declare secondary containment inoperable and take actions as required in Technical Specification Limiting Condition for Operation 3.6.4.1, Condition A, within four hours, adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, and Inspection Manual Chapter 0609, Appendix A, Exhibit 3, Barrier Integrity Screening Questions, dated July 1, 2012, the team determined that the finding is of very low safety significance (Green) because it only represented a degradation of the radiological barrier function provided for the auxiliary building secondary containment. The team determined that this finding has a cross-cutting aspect associated with avoid complacency, in that individuals did not recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Although the surveillance test was documented as Technical Specification Acceptance Criteria Unacceptable because it did not meet the criteria defined in test procedure 06-OP-1T48-R- 0002, Standby Gas Treatment A Logic and Vacuum Test, Revision 115, the licensee did not identify it as a failed surveillance test that affected secondary containment operability. |
