TWO CONTAINMENT ISOLATION VALVES CLOSED DUE TO BLOWN FUSES
The Nuclear Safety and Compliance Group notified Operations today that a report of ESF activation should be made to the NRC. The group noted that during the review of a logic system functional testing on diesel generator 2R43-S001A, a logic power fuse (2A71-F21A) blew closing two primary containment isolation valves (2G11-F003 & 2G11-F019). These valves are the inboard drywell sump isolation valves. This occurred on 4/2/00 at 0030 EDT.
The system was checked, fuses replaced, and the valves opened. The valves are fully operational.
The licensee notified the NRC Resident Inspector.
