What are the principal hazards at a depleted uranium deconversion facility?
Chemical exposure presents the dominant hazard at this type of facility. Uranium and fluoride compounds such as hydrogen fluoride (HF) are toxic at low chemical exposure levels. When depleted UF6 contacts moisture in air, it reacts to form HF and uranyl fluoride gas. Uranium is a heavy metal that can be toxic to the kidneys when taken internally. HF is a corrosive acid that can be very dangerous if inhaled; it represents the principal hazard at this facility. These hazards are controlled by plant design and administrative controls to reduce the likelihood and consequences of an accidental release of these compounds. Such measures include sealed vaults, water suppression systems, controlled ventilation system, and air scrubbers. The U.S. Department of Transportation and the NRC regulate the transportation of depleted UF6 to and from the facility.
