Zusammenfassung: | Provided is a spent nuclear fuel dry storage cask for a light-water reactor which improves cooling efficiency for spent nuclear fuel, has excellent criticality control and stores the spent nuclear fuel. The spent nuclear fuel dry storage cask includes a cask constituting an outer case, a plurality of baskets which store the spent nuclear fuel assemblies and are arranged in the cask, a lead which is installed at the open upper end of the cask and seals the cask, a cooling part which is installed in each of the baskets for absorbing and removing the residual heat of the spent nuclear fuel, and a heat dissipating part which is installed in the lead, is connected to the cooling part and dissipate the heat conducted from the cooling part to the outside.
