| Title | Failure to Identify and Correct a Condition Adverse to Quality Affecting the Operability of the Standby Gas Treatment Train B (Section 1R06) |
| Description | The inspectors identified a Green non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action which states in part, that for conditions adverse to quality, measures shall assure that the cause of the condition is determined and corrective action taken. Specifically, the licensee failed to correct a condition that allowed leakage through a penetration seal in the Unit 1 reactor building supply air ventilation room floor onto the 1B standby gas treatment (SBGT) train control panel, rendering the 1B SBGT inoperable. The licensee entered the issue into their corrective action program and repaired the degraded penetration. The deficiency associated with this event is not adequately sealing the floor penetration in the Unit 1 reactor building supply air ventilation room. The finding is more than minor because it was associated with the containment barrier performance attribute of the barrier integrity cornerstone to provide reasonable assurance that physical design barriers provide protection against radionuclide releases caused by accidents or events. In accordance with Inspection Manual Chapter (IMC) 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, the inspectors conducted a Phase I significance determination process (SDP) screening and determined the finding to be of very low safety significance (Green). The finding was of very low safety significance (Green) because the finding only represents a degradation of the radiological barrier function provided for the SBGT system. The cause of the finding is not related to a cross-cutting aspect because the occurrence was greater than three years ago and is not indicative of current licensee performance. (Section 1R06 |
