| Title | Licensee-Identified Violation |
| Description | In OPCON 4, Hope Creek TS 3.5.2, ECCS - Shutdown, requires that at least two low pressure ECCS subsystems be operable, and with only one ECCS subsystem operable, two subsystems shall be restored to an operable status within four hours or all OPDRV activities must be suspended. Contrary to this requirement, from May 4, at 4:00 a.m. through May 5, 2015, at 10:42 a.m., PSEG conducted an RPV cold hydrostatic test, classified as an OPDRV activity, with only one low pressure ECCS subsystem operable. This condition existed for approximately 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> and 42 minutes. TS compliance was restored at 10:42 a.m. on May 5, 2015, when a second low pressure ECCS subsystem was returned to an operable status. PSEG reported this in accordance with 10 CFR 50.73(a)(2)(i)(B) as a condition prohibited by TS. PSEG entered this issue into their CAP as NOTF 20692069. PSEGs corrective actions for this issue included submitting the required LER per 10 CFR 50.73, performing a causal evaluation, and revising the operability assessment procedure to include guidance clarifying the ECCS TS requirements and determination of operability. The failure to comply with TS 3.5.2 did not have any actual consequences or loss of system safety function because other low pressure ECCS subsystems were available for inventory makeup. Therefore, this finding is of very low (Green) safety significance based on an SDP issue screening, because the ECCS subsystems would have functioned to provide reactor vessel inventory makeup. The closure of the LER associated with this event was documented in Section 4OA3.2 of this report. |
