| Title | Licensee-Identified Violation |
| Description | TS Limiting Condition for Operation 3,6,1,3, Condition A, requires a main steam line flow path to be isolated within eight hours when one MSIV is inoperable in Modes 1, 2, and 3, TS 3,6,1,3, Condition F, requires the unit to be in Mode 3within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, and Mode 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />, if Condition A cannot be met. Contrary to the above, on September 18, 2009, an engineering evaluation determined that the outboard MSIV AO-3-01A-086A did not meet its required TS minimum closure time of greater or equal to three seconds, This determination was based on MSIV stroke time testing performed on September 14,2009, when entering the P3R17 outage, This issue was considered as a condition prohibited by TS since there was evidence that the condition had existed during plant operations, The cause of the event was due to not requiring preventive maintenance for the MSIV oil dashpot needle control valve, PBAPS documented this issue in the CAP as IR 964717, Since PBAPS analysis concluded this condition did not have a significant effect on the safety analysis and the plantnever operated outside of the safety analysis, this issue is of very low (Green)safety significance, The LER associated with the event was documented in Section 40A3,2 of this report. |
