Title | Licensee-Identified Violation |
Description | On March 3, 2013, Energy discovered that the No. 32 turbine-driven AFW pump failed to meet the IST Program full flow test acceptance criteria during its full flow test. A subsequent investigation identified that the steam admission valve failed to stroke properly, which was the result of poor maintenance during the Spring 2011 refueling outage. Specifically, sealant was identified on the turbine thrust bearing housing external surface, which prevented the housing from moving axially to open the steam admission valve. Technical Specification 3.7.5 Limiting Condition for Operation requires all three AFW trains to be operable in Modes 1, 2, and 3. Contrary to this requirement, the No. 32 turbine-driven AFW pump was inoperable for a time period that exceeded the Technical Specification allowed outage time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> (exact time was indeterminate since it was the result of maintenance performed during the Spring 2011 refueling outage). This finding was determined to be of very low safety significance (Green) because the finding did not represent a loss of the entire AFW system or function. Specifically, further detailed evaluation concluded that although the turbine-driven pump was not operable as per technical specifications, the pump remained functional for analyzed transients and accidents. This issue was documented in Entergys CAP as condition report IP3-2013-00887. |
