Stand-alone storage system for spent fuel storage during decommissioning of nuclear power plants

Abstract

An independent storage system for spent fuel storage during nuclear power plant decommissioning comprises: an independent storage space, obtained by modifying a nuclear power plant into a separate building; a spent fuel storage tank, arranged in the separate storage space and configured to store spent fuel; a cooling system disposed in the separate storage space and configured to remove decay heatgenerated from spent fuel; a purification system disposed in the separate storage space, and configured to purify water in a spent fuel storage tank; and a cooling water supply system disposed in theseparate storage space and configured to supply cooling water to the cooling system, wherein the cooling system, the purification system, and the cooling water supply system only perform the functionfor storing spent fuel in the spent fuel storage tank, and the cooling system, the purification system, and the cooling water supply system are arranged in the same building in which the spent fuel tank is arranged.

[0010] Therefore, since the decommissioning of the nuclear power plant is performed in a state where related systems for spent fuel storage are arranged in a dispersed manner outside the nuclear fuel processing building 10 where the spent fuel storage pool 50 is located, the decommissioning of the nuclear power plant is not easy, and workers increased exposure to radiation during decommissioning, possibly due to associated systems for spent fuel storage arranged in a decentralized manner

[0011] In other words, decommissioning of a nuclear power plant is not easily performed because related systems for spent fuel storage used after the decommissioning of the nuclear power plant are arranged in a decentralized manner in buildings other than the nuclear fuel processing building 10 where the spent fuel storage pool 50 is located. , and workers will be more exposed to radiation
