| ENS 52408 | 1 December 2016 17:30:00 | Agreement State | Agreement State Report - Non Contaminated Water Leak Into a Contaminated Bermed Area | The following report was received from the State of Tennessee via email: On December 3, 2016, M & EC (East Tennessee Materials & Energy Corporation) staff notified DRH (Tennessee Division or Radiological Health) regarding an event in which a (Fire Protection) water line outside an M & EC building began leaking (on 12/1/16). The water entered the building flooding a non-contaminated area (radiologically clean) and a bermed contaminated area. After the leak was stopped, water removal was performed Friday and over the weekend. M & EC staff were able to segregate removal of water from the clean area from removal of water from the bermed contaminated area. A total of (approximately 136,000 to 242,000) gallons was removed, a large percentage of which was in the contaminated area. M & EC is in process of completing the clean up, and is also in the process of performing radio-analysis of both the clean and the contaminated water. The contaminated bermed area had an average contamination of (approximately) 15,000 dpm/100 cm2. No release to the public has occurred and a follow-up investigation by the Tennessee DRH is being conducted and additional information will be provided by DRH when available. Report #: TN-16-173 |
