Title:
SPENT NUCLEAR FUEL CANISTER WITH IMPROVED CORROSION RESISTANCE AND MECHANICAL PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2022/231195
Kind Code:
A1
Abstract:
In a spent nuclear fuel canister according to the present invention, an alloy with a specific composition is used, and a mixed filler having fillers, which fill the inside of the canister and have different compositions and shapes, can be applied in a multi-layer structure, so that the spent nuclear fuel can maintain high durability even in a highly corrosive environment resulting from the generation of decay heat of spent nuclear fuel and an environment to which external impact may be applied, and thus has excellent chemical resistance and corrosion resistance. Furthermore, the spent nuclear fuel canister has an effect of facilitating the release of decay heat generated from the spent nuclear fuel located inside the canister and an effect of having a self-sealing function of preventing the radiation emitted from the spent nuclear fuel located inside the canister from being exposed to the outside when the canister is damaged by external impact, corrosion, or the like.
