| Title | Non-Conservative Acceptance Criteria Specified in SBGTS Surveillance Procedure |
| Description | The inspectors identified a NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, because Exelon did not ensure that the surveillance test procedure utilized for the standby gas treatment system (SBGTS) included appropriate acceptance criteria to determine the maximum allowable differential pressure (dP) for the high efficiency particulate absolute (HEPA) filters. Exelons corrective actions included performing a technical evaluation to assess the operability of the SBGTS and revising the surveillance test procedure and control room alarm response procedure. This issue has been entered into Exelons corrective action program. The finding was more than minor in accordance with IMC 0612, Appendix B (Section1-3), Issue Screening, because it was associated with the procedure quality attribute of the barrier integrity (maintain radiological barrier functionality of SBGTS trains BWR only) cornerstone and affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. In accordance with IMC 0609.04 (Table 4a), Phase1 Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance (Green). The performance deficiency had a cross-cutting aspect in the area of human performance, resources (IMC 0305, Aspect H.2(c)), because Exelon did not ensure that accurate procedures were available for the surveillance test. Specifically, the acceptance criteria specified in the surveillance test procedure was not the same and was nonconservative to that specified in the Oyster Creek technical specifications |
