Re: KEY MESSAGES RE: TMI Contamination Event I understand they had to pass through monitors. The word evacuation is more emotionally charged than "sent home" after going through a monitor. Have any workers returned to the plant to work?

RE: KEY MESSAGES RE: TMI Contamination Event

Beth, The workers had to exit (evacuate) the containment building when the alarms were received. As required, they have to be monitored when they exit the containment building. Some were contaminated, so they were decontaminated, sent for a whole body count to assess dose exposure, and then sent home.

KEY MESSAGES RE: TMI Contamination Event Key Messages 9 On November 21, 2009, an airborne contamination event occurred inside the containment building (also known as the reactor building) at Three Mile Island (TMI).

1C/

  • The event had no affect on public health and safety.

e No contamination was found outside the containment building.

  • Approximately 150 workers were evacuated from the containment building and processed through the licensee's portal radiation monitors.

" Workers that were not able to clear the portal monitors were decontaminated and proceeded to be whole body counted.

" Some workers received unplanned occupational dose exposures. However, based on information provided by the licensee, the level of dose received was within a small fraction of the NRC's regulatory limit.

" The NRC has dispatched technical experts to independently review and confirm the licensee's technical assessment.

" The licensee continues to investigate the cause of the event.

" The NRC's resident inspector is onsite and is monitoring the licensee's ongoing activities.

" The NRC has been responding to media questions and plans a press briefing today at the TMI training center.
