Power Operation Event Text HIGH PRESSURE COOLANT INJECTION SYSTEM INOPERABLE "On 7/19/05 at 0345,
maintenance technicians were performing a voltage check during an I&C surveillance when a lead slipped, making inadvertent contact within the panel.
This resulted in shorting of a power connection and blowing a fuse. This fuse supplied initiation and trip logic components associated with the High Pressure Coolant Injection (HPCI) system, the 'A' Core Spray system, and the 'A' Residual Heat Removal (RHR) system. Loss of the HPCI system is reportable under 10 CFR 50.72(b)(3)(v) as a loss of a single train safety system required to mitigate the consequences of an accident.
"Hope Creek entered Technical Specification (TS) 3.0.3 for HPCI inoperability with one Core Spray and one RHR system inoperable.
Actions to replace the fuse and restore operability of the HPCI system were completed at 0909 on 7/19/05, allowing exit from TS 3.0.3. Actions to commence staffing for a shutdown and implement required procedures were implemented, however a power reduction was not initiated based on successful restoration.
"The remaining retest activities associated with fuse restoration were completed for the 'A' Core Spray Loop and the 'A' RHR system at 0923 on 7/19/05, clearing the remaining Limiting Conditions for Operation associated with the fuse failure.
No additional Emergency Core Cooling Systems or safety related equipment was inoperable during this time period." The licensee notified the NRC Resident Inspector and Lower Alloways Creek Township.
