Title | VIOLATION OF 10 CFR 50.73(a)(2)(i)(B), FAILURE TO REPORT CONDITION PROHIBITED BY TSs |
Description | Inspectors identified a Severity Level (SL) IV NCV of 10 CFR Part 50.73 (a)(2(i)(B) for PPLs failure to submit a Licensee Event Report (LER) of a condition prohibited by plant TS associated with seat leakage from the Unit 1 D outboard main steam isolation valve (MSIV). On April 8, 2012, the D outboard MSIV failed to pressurize during its LLRT indicating that leakage was in excess of its TS limit. The same MSIV had failed to pressurize during its LLRT in 2010. The inspectors determined there was firm evidence to indicate that seat leakage from the MSIV was in excess of the TS limits during the previous two operating cycles for greater than the allowed outage time of 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />, which constitutes a condition prohibited by TS 3.6.1.3. PPL entered the issue into the CAP as CR 1590506. This finding was evaluated using the traditional enforcement process because the failure to accurately report events has the potential to impact or impede the regulatory process. The finding was determined to be a Severity Level (SL) IV NCV based on example 6.9.d.9 of the NRC Enforcement Policy. The significance of the associated performance deficiency was also screened against the ROP per the guidance of IMC 0612, Appendix B, lssue Screening. No associated ROP finding was identified and no cross-cutting aspect was assigned. |
