| Event Description | At 0911 EDT, the Susquehanna LLC Shift Manager was notified that a member of the SSES [Susquehanna Steam Electric Station] work force was feeling ill effects from a Freon-12 leak located in a plant vital area. This met the declaration criteria for an Alert under [EAL] OA-7 of the emergency plan which was declared at 0922 EDT.
The affected area has been evacuated and recovery actions are in progress to isolate the leak. No personnel were injured or medical attention was required.

No outside assistance is required. Notified DHS (Hill), FEMA (Heyman), DOE (Smith), USDA (Mitchell) and HHS (Rolle).
At 2335 EDT on 8/10/10, the Alert was terminated. The Chiller has been evacuated of Freon-12. Freon detectors show no presence of Freon-12 on U1 Reactor Building Elevation 749 [feet], except in the immediate vicinity from the leak site with temporary ventilation in service. All state and local agencies have been advised, the NRC Resident Inspector has been notified and a press release will be made. Agencies that the licensee notified included the Columbia County Emergency Management Agency, the Luzerne County Emergency Management Agency, the Pennsylvania Emergency Management Agency and the Pennsylvania Department of Environmental Protection.
