b'1975 Hot Fuel Examination FacilityArgonne-Wests flagship facility for conducting post-irradiation examination of fuels and materials began operations in 1975. HFEF is a large, heavily shielded, alpha-gamma hot cell facility designed for remote examination of highly irradiated fuel and structural materials. A critical component of the research needed to develop new nuclear technologies, HFEF is a national research asset with the nations largest inert atmosphere hot cell dedicated to radioactive materials research. The main hot cell is 70 feet by 30 feet with 15 workstations, each at a 4-foot-thick window. It can accept full-size light water reactor fuel assemblies, and its capabilities include nondestructive and destructive examination.53'
