| Event Text UNPLANNED ONSITE MEDICAL TREATMENT OF A CONTAMINATED WORKER
"An employee experienced a minor thermal burn to the leg and reported to the on-site dispensary this morning. The plant nurse administered first aid. A whole body survey of the employee's plant clothing was performed; the maximum amount of contamination present was on the employee's work boots, 15,949 dpm/100cm2. The plant nurse allowed the employee to return to work following treatment. The employee remained inside the Restricted Area over the entire course of the event.
"Contamination due to uranium ore concentrates."

"Conditions were met that require immediate NRC notification per 10 CFR 50.72(b)(3)(v)(B) and 10 CFR 50.72(b)(3)(v)(D) due to both trains of the Ultimate Heat Sink (UHS) system being inoperable for approximately 83 minutes. This condition resulted from a planned system outage of train B Component Cooling Water (CCW), as a subsystem of the Train B UHS, and an unexpected trip of a Train A Auxiliary Component Cooling Water (ACCW) Wet Cooling Tower (WCT) fan, which is also a subsystem of the Train A UHS.
"CCW Train B was declared inoperable at 0820 CDT and removed from service for a planned relay replacement, resulting in entry of 72 hour shutdown Technical Specification (TS) LCO 3.7.3, and associated cascading TS on Train B, including TS LCO 3.7.4 Action a. Subsequently, at approximately 0853 [CDT], the 6A ACCW WCT fan tripped, rendering the redundant Train A UHS inoperable, causing entry into 1 hour TS LCO 3.7.4 Action b, which states, 'With both UHS trains inoperable, restore at least one UHS train to OPERABLE status within 1 hour or be in at least HOT STANDBY within the next 6 hours and COLD SHUTDOWN within the following 30 hours.'
"At approximately 0948 CDT the WCT Fan 6A electric motor thermal overload relays were reset, the fan restarted, and operated properly. At 1016 CDT, CCW train B had been restored from the planned maintenance and was declared operable, exiting TS LCO 3.7.3 and associated cascading TSs on Train B. Although a plant shutdown was not commenced following expiration of the one hour specified in TS LCO 3.7.4 ACTION b, Operations was preparing for a power reduction and TS required plant shutdown.
"During this reported condition, an outside air intake valve of the Control Room Emergency Filtration system was inoperable for planned maintenance, for which TS 3.7.6.1 mitigating actions were in place. This valve was restored to Operable at 1210 CDT. Other safety systems remained available. The plant remained stable at 100% during this time."
The NRC Resident Inspector was notified. | |
