Spent Fuel Disposal Canister by passive cooling with heat pipe

摘要

The present invention is a spent nuclear fuel disposal container loaded with spent nuclear fuel bundles 12, and is used for passive cooling using a heater pipe wound so that the heater pipe 2 surrounds the outer circumference of the disposal container loaded with spent nuclear fuel bundles. It is a container for disposal of spent nuclear fuel by The spent nuclear fuel disposal container according to the present invention can minimize the increase in the surface temperature of the disposal container by passively discharging the decay heat of the spent nuclear fuel to the outside without additional power by the heat pipe (2). Compared to the existing spent nuclear fuel disposal container, which holds the spent nuclear fuel, it has the effect of holding more bundles of spent nuclear fuel, and relatively more after use than the existing spent nuclear fuel disposal container. Since bundles of nuclear fuel can be settled, the number of disposal containers or the required area of the disposal site can be reduced, which is advantageous industrially and economically.
