| Title | Loss of Motor Control Center Due to Electrical Short |
| Event Description | An electrical short to the wiring of a Nash vacuum pump caused failure of required operating equipment by shorting out the motor control center and blowing a fuse that supplies power to the Nash vacuum pump, health physics vacuum pumps which provide flow for building air samplers, floor high airborne radioactivity warning lights, and other support equipment and instrumentation. The UF6 processes were shut down and announcements were made to require any personnel who entered any floor in the feed materials building to wear a respirator. There was no release of radioactivity to the environment and power was restored in approximately thirty minutes and process operations were resumed. Air samples were counted on all floors in the Feed Materials Building and no high airborne radioactivity was detected. The floor air samples were counted again in approximately four hours and no airborne radioactivity was detected. An investigation is being conducted and the results will be included in the 30 day written report.
The licensee informed NRC Region II John Pelchat of the event. |
