Abstract
A transitory or temporary storage for highly radioactive waste, in which the transitory storage incorporates containers for the receipt of the waste, and a cooling system for the discharge of the heat which is produced during the storage of the waste. The cooling system incorporates a cooling air duct, as well as a coolant circuit for a coolant which is conveyed in a closed circuit between coolant conduits which conduct off heat generated in the storage space and a heat sink arranged externally of the storage space.
Claims20
A storage vessel for radioactive waste comprising:
- outside storage walls forming an enclosed storage space;
- an axially extending storage container supported in the storage space and forming a plurality of axially extending storage shafts for receiving the radioactive waste;
- a primary cooling circuit for conducting a cooling fluid from a source thereof, through the storage container, and to heat a sink to remove heat produced in the storage container, the primary cooling circuit including a multitude of axially extending cooling conduits forming a pattern encompassing the storage shafts;
- and
- a cooling mantle extending around the storage container and forming therewith an axially extending cooling air passageway for conducting air upward past the outside of the storage container;
- the outside storage walls and the storage container forming an air distribution chamber, below the storage container, to distribute cooling air to the air passageway;
- the outside storage walls including internal air conduit means for conducting air downward, through the storage walls, from an upper portion of the storage vessel to the distribution chamber
- said cooling air passageway, air distribution chamber, and internal air conduit means comprising an auxiliary, air cooling circuit for the storage container.
