High-level radioactive material is delivered to the
Canister Storage Building.
The U.S. Department of Energy and contractor CH2M HILL Plateau Remediation Company are safely and compliantly managing radioactive and mixed waste stored at the Central Waste Complex at the Hanford Site in southeastern Washington State.
The Canister Storage Building (CSB) plays an important role as an interim storage facility in Hanford’s cleanup mission.
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 containing about 2,300 tons of irradiated fuel that came from several Hanford facilities. The irradiated fuel was cleaned, packaged, dried, and relocated to the CSB to provide safe interim storage in a consolidated location.
The CSB is composed of three belowgrade concrete vaults, each capable of holding 220 carbon steel tubes. The tubes, each 40 feet (12 meters) long and 28 inches (71 centimeters) in diameter, have been placed vertically in the vaults. Multi-canister overpacks are safely stored in the tubes in these vaults until a final disposal decision is made. Currently, only one vault contains multi-canister overpacks; 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 a national repository.
- Below the floor of the CSB, there are numerous vertical storage tubes in three concrete vaults.
- Each carbon steel storage tube is 40 feet long and 28 inches in diameter.
- Annual operating costs are approximately $5 million for safe storage of nuclear materials.
- Approximately 2,300 tons of spent nuclear fuel is stored in the tubes in the CSB.
