CALIFORNIA AGREEMENT STATE REPORT - STOLEN NUCLEAR GAUGE
A Troxler moisture density gauge was stolen from the back of a pickup truck parked at a licensee employee's residence sometime between 2000 PDT 05/17/05 and 0550 PDT on 05/18/05. The gauge was in its transportation case and the case was strapped down (vice chained) in the back of the truck. The employee delayed notification to the licensee until 5/26/05. The licensee notified the State at 1100 PDT on 05/27/05. The Los Angeles Police Department was notified and the licensee is offering a reward for return of the gauge. The licensee also notified the gauge manufacturer's local representative.
The Troxler was a model 3440, Serial Number 29792, with an 8 milliCuries Cs-137 and a 44 milliCuries Am-241/Be source. |

CONTAMINATED INJURED PERSON TAKEN TO OFFSITE HOSPITAL
"During the R-17 refueling outage, a contract worker fell approximately 15 feet in the condenser. The individual was conscious but unable to egress from the main condenser due to injuries sustained from the fall. A response team was used to bring the worker out of the plant.
"Health Physics (HP) technicians accompanied the worker to the hospital. The individual has been transported to Kadlec Medical Center by the Hanford Fire Department. The HP technicians surveyed the individual at the hospital and discovered contamination.
"The ENS notification is being made because of the transport of a potentially radioactive contaminated person to an offsite medical facility for treatment. FEMA, State of Washington and local representatives have been notified." A press release will be issued.
The licensee notified the NRC Resident Inspector. |

REACTOR SCRAM DUE TO GENERATOR TRIP/TURBINE TRIP FOLLOWING OFFSITE ELECTICAL TRANSIENT
The licensee reported that an offsite electrical transient on the 230KV transmission line appears to have caused a generator trip and corresponding turbine trip and reactor scram. The scram was uncomplicated. All rods fully inserted. No safety relief valves lifted during the transient. The reactor is stable at 920 psi with decay heat being discharged to the main condenser and fed via the main feed pumps. There was no loss of offsite power during the transient and the plant is in a normal electrical lineup.
The specific cause of the generator lockout is still under investigation but is believed to have been caused by maintenance work at the Manitou 230KV substation about 25 miles from the plant. Lightning arrestors were being placed in service at the substation and are believed to have resulted in an electrical disturbance on the grid. The licensee notes that switchgear for the stack lighting did trip during the transient and so the FAA was notified on the stack lighting outage.
The licensee plans to remain in hot shutdown for approximately 24 hours before restart.
The licensee notified the NRC Resident Inspector. |
