| Title | Ts Required Shutdown at Nmp1 Due to Inoperable Msiv |
| Event Description | During the performance of a normal orderly planned shutdown for maintenance a packing leak was discovered on Main Steam Inboard Isolation Valve 01-02 (01-02). Drywall inspection results revealed MSIV 01-02 operator gear housing degraded allowing grease to be lost. Engineering assessment of the condition of the limitorque operator of MSIV 01-02 is not able to provide enough information to support operability of MSIV 01-02. Declaring MSIV 01-02 inoperable. Entering T.S. 3.2.7(b and c). Action required to close one valve in the line having an inoperable valve or initiate a normal orderly shutdown with in one hour and be in cold shutdown within ten hours. Entering T.S. 3.3.4(b and c). Action required to close one valve in the line having an inoperable valve within four hours or reduce reactor coolant temperature to a value less than 215 degrees F within ten hours. Most limiting action required in current condition is 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> to be in cold shutdown. 01-02 will be closed as soon as all rods are in.
