While investigating a Unit 1 high pressure … While investigating a Unit 1 high pressure coolant injection (HPCI) room instrument sump level high alarm, condensation was observed dripping out around the HPCI turbine shaft gland seals. A steady stream of water was also observed coming out of the governor end gland seal along with a slight leak coming from the coupling end. Observation revealed that leakage through the 'closed' steam admission valve (1E41-F001) was apparently resulting in water accumulation in the HPCI turbine. A blown fuse that prevented the associated HPCI exhaust drain pot from draining in conjunction with the leakage by the steam admission valve was determined to be sufficient to impact HPCI operability. Required actions were taken in accordance with the Technical Specifications.</br>Efforts are underway to determine the actions needed to restore the HPCI system to operable status.</br>The licensee has notified the NRC Resident Inspector.</br>* * * UPDATE FROM JOHN SELLERS TO CHARLES TEAL AT 0154 EDT ON 5/2/14 * * *</br>HPCI has been restored to an Operable but degraded nonconforming condition.
