Preliminary Notice of Violation issued to Bechtel Hanford, Inc., related to Violations of Nuclear Safety Regulations at the Hanford Site, (EA-2000-06)
This letter refers to the Department of Energy’s (DOE) evaluation of violations of DOE’s nuclear safety regulations associated with the unplanned exposure of workers to airborne radioactivity at the 105B Transfer Bay in June of 1999. During that event, workers unwrapped a highly contaminated Filter Press without utilizing appropriate engineering and/or administrative controls. As a result, an Airborne Radioactivity Area was created which was not adequately recognized, posted, or controlled. For an approximate 13-day period, workers continued to periodically access the Transfer Bay without controls (respiratory protection) appropriate to the radiological hazard.
