| ENS 45214 | 21 July 2009 11:30:00 | A licensee representative of Cobra Natural Resources LLC called concerning an accident at a coal mine loading facility where a device containing radioactive sources was stored. A train derailment of five empty coal cars at the mine damaged a "loadout" building where a process gauge with radioactive sources was stored. Due to debris at the site of the incident, the licensee is unable to reach the gauge but it appears intact and undamaged. The gauge contains four Californium-252 sources with at total activity of less than 80 mCi. The licensee RSO is continuing to evaluate the situation.
The RSO for the licensee reports that its contractor, Thermo-Fisher, has been able to perform close-in area surveys of the device using a remote probe. The surveys confirmed that there is no contamination. Remote visual examination also revealed no indication of damage. The device, a Gamma-Metrics coal analyzer, is still not accessible due to personnel risk from the building debris but the licensee believes that there is no risk of damage to the device until it can be retrieved. The licensee has discussed this event with NRC Region 1 (Miller) and FSME (Villamar). R1DO (Rogge) notified. |
