AGREEMENT STATE REPORT - IRRADIATOR SAFETY INTERLOCKS BYPASSED
A fuse blew during operation of an irradiator facility in Broken Bow, NE. This affected: the source up or down indication, the roof plug switch, the high temperature sensor, and the source movement light. The system could not be reset manually with the key. To verify the source was in the shielded position, an operator was sent to the roof and verified that there was no slack in the cables and the position of the cables indicated the source was in the shielded position. The interlocks were bypassed and an operator entered the cell. It was determined that there was a blown fuse and faulty wiring which were replaced. Operators did not receive any radiation dose from this event.

MANUAL REACTOR SCRAM DUE TO A MAIN TURBINE DIGITAL ELECTRO-HYDRAULIC CONTROL SYSTEM LEAK
"At 0725 hours, a manual scram was inserted due to a Main Turbine Digital Electro-Hydraulic (DEH) control system leak and anticipated turbine trip on loss of DEH tank level. Initial investigation identified a DEH leak at the area of the Quad-Voter hydraulic trip subsystem on the high pressure turbine.
"All rods fully inserted, main steam isolation valves (MSIVs) remained open, no safety/relief valves (SRVs) opened, and all other safety systems operated as designed. Reactor water level was restored and maintained with the Reactor Feedwater and Condensate systems during the post-scram transient within normal operating bands. Reactor pressure was controlled using main steam drain lines. A normal cooldown to the condenser is in progress. Offsite power is available. All three emergency diesel generators are operable and available."
The plant was operating at 52% for planned maintenance. All safety systems remain available.
The licensee has notified the NRC Resident Inspector.
