Abstract: An underground passively ventilated nuclear waste storage system includes an array of cavity enclosure containers each including a cavity holding a nuclear waste canister containing radioactive waste generating heat. Each container comprises at least one pair of air inlets each fluidly coupled directly to separate vertical cooling air feeder shells spaced apart from the container. The feeder shell in fluid communication with ambient air operates to draw in ventilation air which flows to the container via natural convective thermo-siphon effect driven by heat emitted from the canister which heats the container cavity. The containers are arranged in a serial spaced apart manner in multiple parallel rows. The containers within each row are fluidly isolated from containers in other rows. Containers within each row are further fluidly isolated from other containers therein when the ventilation system operates. The containers may be part of a consolidated interim storage facility for radioactive waste.

Abstract: A nuclear waste cask in one embodiment includes an axially elongated cask body defining a longitudinally-extending opening forming an entrance to an internal storage cavity of the cask configured for holding radioactive nuclear waste materials. A closure lid detachably coupled to the cask body at the top opening seals the cavity. A cask locking mechanism includes a plurality of first locking protrusions spaced apart on the lid which are selectively interlockable with a plurality of second locking protrusions spaced apart on the cask body to lock the lid to the cask body. The first locking protrusions may be disposed on slideable locking bars moveable between locked and unlocked positions while the lid remains stationary on the cask body. Hydraulic or pneumatic actuators may be used to change position of the locking bars. The cask and lid may include other features such as impact absorbers and lifting elements.

Abstract: A method of storing high level radioactive waste, and specifically a method of adjusting or controlling the temperature of ventilation air flowing through a storage cavity of a ventilated system. The method includes positioning a metal canister containing high level radioactive waste in a storage cavity of the ventilated system. The ventilated system includes a cask body, a cask lid, a plurality of inlet ducts, and at least one outlet duct so that ventilation air can flow from atmosphere into the storage cavity where it is heated and then back out to the atmosphere. The method includes progressively reducing a cross-sectional area of one or more of the inlet ducts and/or the outlet duct over time so that a rate at which the ventilation air is heated within he storage cavity is maintained above a predetermined threshold to mitigate the risk of stress corrosion cracking in the metal canister.

Abstract: A containment cask for safely transporting and storing radioactive hazardous waste in a dry air environment. The cask comprises a single drum containing the radioactive hazardous waste, a sealed and shielded containment vessel containing the drum, and an outer container. The outer container can be in the form of an outer shield vessel (OSV) made from iron to provide further shielding. This outer container is appropriate for a drum having higher activity waste. The outer container can also be in the form of an overpack assembly that adds protection for atmospheric hazards, but adds little in terms of shielding. This outer container is appropriate for a drum having lower activity waste.
