摘要： The present invention provides a system and method for reclaiming energy from the heat emanating from spent nuclear fuel contained within a canister-based dry storage system. 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nuclear fuel within the canisters so that spent nuclear fuel that is hotter than that which is typically allowed to be withdrawn from the spent fuel pools can be used in a dry-storage environment, thereby increasing the amount energy that can be reclaimed.

摘要： A neutron absorbing apparatus, for insertion into a fuel cell storage system, includes a corner spine, a first all and a second wall, each wall being affixed to the corner spine to form a chevron shape. Each wall includes an absorption sheet affixed to the corner spine, each absorption sheet being formed of a metal matrix composite having neutron absorbing particulate reinforcement, and a guide sheet affixed to and covering a fractional upper portion of the absorption sheet and extending over a top of the absorption sheet. The absorption sheet extends along the corner spine a greater length than the guide sheet.

摘要： A canister for storing radioactive materials includes a base plate, side wall and a top plate. The top plate includes a top surface with a top edge having a bevel, and with a channel set in from the top edge. The top plate is sealed to the sidewall by a weld formed between the beveled top edge and the top of the side wail. The base plate is sealed to a bottom of the sidewall, so that a sealed vessel is formed.

摘要： A method for preparing a cavity loaded with wet radioactive elements for dry storage, the method including: connecting a condensing module, a vacuum module, and a gas circulator module to the cavity so as to form a hermetically sealed closed-loop path that includes the cavity; filling the closed-loop path with a non-reactive gas; circulating the non-reactive gas through the closed-loop path until the condensing module is no longer removing substantial amounts of water from the circulating non-reactive gas, wherein the vacuum module is sealed off from the closed-loop path during the circulating; discontinuing the circulation of the non-reactive gas through the closed-loop path; fluidly coupling the vacuum module to the cavity and fluidly isolating the cavity and the vacuum module; and applying a vacuum pressure to the cavity via the vacuum module so as to create a sub-atmospheric pressure within the cavity.
