.Aaron,

-Here is the Event Notification for the Three Mile Island 1 worker contamination event on Saturday.

The containment building was evacuated of approximately 175 workers after alarms sounded due to high airborne radiation levels. After checking the workers, it was determined 16 had measurements of between 10 and 20 millirems, two between 20 and 30 millirems and one between 30 and 40 millirem. A millirem is a measurement of exposure to radiation. The average American receives about 360 millirems of radiation exposure each year, from natural and manmade sources. The annual federal limit for occupational exposure to radiation is 5,000 millirems.

Exelon is currently performing minimal work inside the containment building until the cause of the event is fully understood.

Our Resident Inspectors reported to the site on Saturday to monitor the company's response to the event.

Yesterday, we had two radiation safety specialists on site, as well. The NRC will continue to follow Exelon's actions, including its development of a root cause evaluation.

Please let me know if you need additional information.

Management Agency and local counties for an event of potential public interest. This notification was made at 22:45 on November 21, 2009, after the occurrence of an event related to the safety and health of onsite personnel for which a press release has been made. The press release was made following the event of potential public interest notifications. This report is being made under 10 CFR 72.75(b)(2).

"At approximately 16:00 on Saturday November 21, 2009, low levels of radiation activity were measured on radiation monitors installed in the TMI-1 reactor building. Personnel were directed to immediately leave the reactor building until the source of the activity could be identified. Surveys directly outside of the reactor building construction opening indicated a slight increase in activity. Levels have returned to normal. No contamination was identified outside of the reactor building. Approximately 150 workers were monitored for exposure to the radiation activity. No worker approached or exceeded any exposure limits. The sources of the activity are believed to be from maintenance tasks related to cutting lines in preparation for removal of the 'B' Steam Generator."

The licensee is still investigating the cause of the event but indicated that the radiation release is no longer in progress.

Containment Ventilation is established to provide an inflow into containment to the extent possible (considering the openings in containment).
