Title | High Pressure Coolant Injection System Rendered Inoperable |
Event Description | On 6/17/2016, 2-SR-3.3.6.1.6(3) HPCI [High Pressure Coolant Injection] system time delay relay calibration periodic surveillance was being performed. During a section in the procedure a fuse cleared for the logic bus B power at 2135 [CDT]. This rendered the HPCI system unable to be manually or automatically initiated. At 2239 the fuse was replaced and the HPCI system was restored to a standby lineup.
