Preliminary Notice of Violation issued to Westinghouse Savannah River Company, related to an Unplanned Radioactive Material Intake at the Savannah River Site, (EA-97-12)
This letter refers to the Department of Energy's (DOE) evaluation of the facts and circumstances surrounding an unplanned intake of radioactive material [ ] by a worker that resulted in the worker receiving an occupational whole body dose of [a specifed value] Total Effective Dose Equivalent (TEDE). The intake, which exceeds the regulatory limit of 5 rems, was identified in April 1997 during a review of the worker's routine bioassay sample results. Subsequent investigation by the Westinghouse Savannah River Company (WSRC) identified numerous instances in which radiological work was not performed in accordance with established procedures, standards, and administrative controls and concluded that the intake likely occurred in December 1996 while the worker was participating in hut removal activities in the F-Canyon. A DOE investigation likewise identified numerous instances in which radiological work was not performed in accordance with established procedures, standards, and administrative controls and concluded radiological conditions existed with the potential to have caused the intake. The Office of Enforcement and Investigation conducted an evaluation of these matters in July 1997 and issued an Investigation Summary Report which was transmitted to you on October 8, 1997.
