Structural Integrity Program for Calcined Solids Storage at the U.S. Department of Energys Idaho Site M. K. Adler-Flitton CH2M-WG Idaho, LLC, Idaho Falls, Idaho USA Abstract The calcined, high-level

The calcined, high-level radioactive wastes at the U.S. Departmentof Energy’s (DOE) Idaho Site are stored in stainless steelbins that are contained in concrete vaults to isolate the bins fromthe atmosphere. The storage facility is termed the Calcined SolidsStorage Facility (CSSF) and contains approximately 155,300 feet3of calcine. Safety analysis information, including seismic and tornadoevaluations, are coupled with corrosion evaluations andcorrosion monitoring to demonstrate that the CSSF is currentlystructurally sound and should be fi t for service for at least 500years. This paper summarizes the structural integrity program forthe CSSF.
