The inventive system and method provides continuous passive cooling of the loaded canisters by utilizing the chimney-effect and reclaims the energy from the air that is heated by the canisters. The inventive system and method, in one embodiment, is particularly suited to store the canisters below-grade, thereby utilizing the natural radiation shielding properties of the sub-grade while still facilitating passive air cooling of the canisters. In another embodiment, the invention focuses on a special arrangement of the spent nuclear fuel within the canisters so that spent nuclear fuel that is hotter than that which is typically allowed to be withdrawn from the spent fuel pools can be used in a dry-storage environment, thereby increasing the amount energy that can be reclaimed.

  • Patent number: 9395263
    Abstract: The present invention discloses a method for inspecting sealability of a vacuum chamber. The vacuum chamber has a closed site in which two sealing rings are arranged in such a way that the two sealing rings form therebetween a sealed compartment. The sealed compartment has a wall in which an evacuation hole is formed. The method for inspecting sealability of a vacuum chamber includes: connecting an evacuation valve through a pipe to the evacuation hole to form evacuation piping; mounting a pressure meter to the evacuation piping; opening the evacuation valve to proceed with evacuation of the sealed compartment and, during the evacuation process, monitoring the pressure meter; and determining sealability of the two sealing rings according to a reading of the pressure meter. The present invention allows for quick evacuation of the sealed compartment and to determine the sealability of the two sealing rings according to the pressure meter.

  • Patent number: 9117558
    Abstract: Systems and methods of the disclosure are directed toward removing moisture from, and controlling the temperature of, spent nuclear fuel stored in spent fuel containers and the containers themselves. A vacuum system may remove vapor and gas from the container to reduce pressure and stimulate moisture evaporation. The potentially radioactive gas exiting the spent fuel container can also be transported to a radioactive waste gas system. A non-reactive gas is then circulated through a circulation path, which is communicatively coupled to a spent fuel container. The non-reactive gas can absorb heat and/or moisture from the spent fuel stored within the spent fuel container. Accordingly, heat can be removed by a heat exchanger coupled to the circulation path. Condensate moisture can also be removed from the circulation path.
