Embodiment Construction

[0042] figure 1 is a block diagram illustrating techniques for managing spent fuel 104 from one or more nuclear reactors 152 in a nuclear reactor power system 150 . The technique includes removing spent nuclear fuel rods 104 from the nuclear reactor 152 and transferring the spent fuel rods 104 to a spent fuel management system 154 that facilitates removal of residual decay heat generated by the spent fuel rods 104 . Spent fuel management system 154 includes a plurality of spent fuel tanks 100 submerged in a spent fuel pool 156 filled with fluid 158 . The fluid 158 provides a heat sink for receiving and dissipating the decay heat from the spent fuel rods 104 . As described in detail below, tank 100 may be configured to operate passively, eg, without operator intervention or supervision, under both normal conditions and abnormal emergency conditions. In some examples, canister 100 provides a long-term decay heat removal solution for spent fuel rods 104 . For example, tank 100...

Description

technical field [0001] The present disclosure generally relates to systems and methods for storing and managing spent nuclear fuel. Background technique [0002] Spent fuel pools provide long-term decay heat removal from fuel that has recently been discharged from a nuclear reactor. Recently drained nuclear cores typically represent the greatest source of heat generation in spent fuel pools. In the event of a complete loss of power to the nuclear power plant, the cooling system for spent fuel pools may not be available to remove the fuel's decay heat. For prolonged nuclear power plant outage conditions, with recently drained fuel, there is a potential to boil all the water in the spent fuel pool, thereby overheating and subsequently damaging the spent fuel bundle. This can result in a radioactive release to the environment. Contents of the invention [0003] This disclosure describes technology related to systems, devices, and methods for processing, storing, and otherw...
