Hot Fuel Examination Facility

The Hot Fuel Examination Facility (HFEF) is a multiprogram hot cell facility. There are two adjacent shielded hot cells (the main cell and decontamination cell), a shielded metallography box, an unshielded hot repair area and a waste-characterization area. HFEF provides shielding and containment for remote examination, processing and handling of highly radioactive and TRU-bearing materials in its argon-atmosphere hot cells, unshielded labs, support areas and special equipment for handling, examining and testing of highly radioactive materials.
