| Title | Failure to Follow Procedure Resulted in Inoperable PRF System Boundary |
| Description | The NRC identified a Green non-cited violation (NCV) of Technical Specification (TS) 5.4.1.a, Procedures, when inspectors found the 1A containment spray (CS) pump room door (door 106) open on May 12, 2017, without the required dedicated individual to close the door. As a result, the penetration room filtration (PRF) system boundary was inoperable which rendered both trains of the PRF system inoperable. Failure to follow section 19.0 of licensee procedure FNP-0-SOP-0.0, Version 163, was a performance deficiency. The performance deficiency was more than minor because it was associated with the structure, system, component and barrier performance attribute of the barrier integrity cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protec t the public from radionuclide releases caused by accidents or events. Specifically, when door 106 was open, the PRF system boundary was inoperable, which caused both PRF trains to be inoperable. Without the dedicated individual to close the door as directed, the ability of the PRF system to perform its safety function was compromised. The significance of this finding was evaluated using IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated June 19, 2012. This finding was of very low safety significance (Green) because the finding only represented a degradation of the radiological barrier function provided for the auxiliary building through the PRF system. The inspectors determined the finding had a cross-cutting aspect of Teamwork in the Human Performance area because maintenance did not effectively communicate and coordinate their activities with operations to ensure the requirements were met when door 106 was left open [H.4]. |
