AGREEMENT STATE REPORT OF LOST TRITIUM EXIT SIGNS

During major construction, five out of eight exit signs were discovered missing in September 2003. Each exit sign contained 20 Curies Tritium as of 12 years ago. As of today each sign contains about 10 Curies Tritium. These exit signs are Generally Licensed devices and were manufactured by Fisher. The owner investigated and interviewed several employees within the last 30 days and advised them that if they find the signs they should bring them to him. As of today, the signs have not been recovered. The owner also reported that the facility brought about 100 dumpsters to the facility for inspection of debris and that the exit signs were not picked-up with the debris.

Event Text

A LEVEL 3 LOW REACTOR WATER LEVEL WAS REACHED DURING A REACTOR WATER LEVEL TRANSIENT

The reactor was being shutdown as part of a planned evolution to allow repairs on the Reactor Water Cleanup flange leak. After the Reactor Protection System Mode Select Switch had been placed in shutdown, the resulting reactor level transient caused the Level 3 low reactor level set point to be reached. The Reactor Protection System had already been de-energized and the lowest level reached during the transient was +2 inches. This level transient is a normal occurrence on a reactor shutdown, and level was restored to the normal operating band. There was no effect on the plant due to reaching the low level set point. No other abnormal plant response was noted.

The licensee will notify the NRC Resident Inspector
