Title: NUCLEAR POWER PLANT SPENT FUEL STORAGE AND TRANSPORTATION METAL TANK
Abstract:
A nuclear power plant spent fuel storage and transportation metal tank comprises a metal tank (1) and a fuel basket (2) detachably accommodated in the metal tank. The metal tank (1) comprises: a housing (10); a base (12) hermetically sealed and fixed at a bottom portion of the housing (10); a top cover (14) hermetically sealed and fixed at a top portion of the housing (10); and a redundant top cover (16) hermetically sealed and fixed on the housing (10). In comparison to the prior art, the nuclear power plant spent fuel storage and transportation metal tank resolves issues of safe storage of spent fuel and post-transportation of the spent fuel, realizing long-term safe storage and transportation of the spent fuel. In addition, since that the fuel basket (2) is detachably accommodated in the metal tank, the fuel basket (2) can be used for loading fuel frames having different structures, providing universality.
