| Title | Voluntary Offsite Notification with Potential Media Interest |
| Event Description | This ENS [report] is being voluntarily issued to notify the NRC that voluntary communications were made to offsite agencies this morning between 0700 and 0830 [EDT] due to an event of potential public interest.
At approximately 1 a.m. on September 1, 2012, Peach Bottom outage workers on the Unit 2 refuel floor were disassembling the reactor head vent when steam discharged from the flange, causing a small but detectable amount of airborne contamination that was contained in the building. All workers were wearing the proper protective equipment and no significant personal [personnel] exposure has been reported. As a precaution, employees were asked to temporarily leave the area for onsite evaluation while radiation protection technicians investigated. Approximately 50 workers were impacted by the radiological airborne event at Peach Bottom and had to stay over shift for radiological monitoring. In accordance with station Radiological procedures, affected personnel are being monitored and as required bioassay is being conducted. Radiation monitors in the reactor building initially detected the airborne contamination, but all have returned to normal levels. This event resulted in no significant impact to the health and safety of our workers or the public. The station made voluntary notifications to the NRC Senior Resident, the State Bureau of Radiation Protection and state and local stakeholders. This issue has been entered into the site Corrective Action Program for evaluation and implementation of further corrective actions. |
