The U.S. Department of Energy and contractor CH2M HILL Plateau Remediation Company are safely and compliantly managing interim storage of waste at the Canister Storage Building at the Hanford Site in southeast Washington state.
Delivery of high level material to the Canister Storage Building.
The Canister Storage Building (CSB) Complex plays an important role in Hanford’s cleanup mission as an interim storage facility.
The CSB is a 42,000-square-foot (3,402 square-meter) facility in Hanford’s 200 East Area. The facility stores about 400 multi-canister overpacks (MCOs) containing about 2,300 tons of irradiated fuel that came from Hanford facilities, primarily the K Reactor Area. The irradiated fuel was cleaned, packaged, dried and relocated to the CSB to provide safe interim storage in a consolidated location.
The CSB is comprised of three below-grade concrete vaults, each capable of holding 220 carbon steel tubes. The tubes, each 40 feet long, have been placed vertically in the vaults. MCOs are safely stored in the tubes in these vaults until they can be permanently placed in a national repository. Currently, only one vault contains MCOs. The other two vaults are available for additional storage needs.
Adjacent to the CSB is the Interim Storage Area, which also contains irradiated fuel packaged in various containers. This irradiated fuel will be repackaged and sent to the national repository.
Workers handle an empty multi-canister overpack.
