Fuel assembly
专利汇可以提供Fuel assembly专利检索，专利查询，专利分析的服务。并且PURPOSE: To lower the pellet temp. of an MOX fuel rod and to improve the defectless property of the fuel rod by setting the spacing between the pellet of the MOX fuel rod and a cladding pipe smaller than the spacing between the pellet of a UO
2 fuel rod and the cladding pipe.
CONSTITUTION: The pellet 9a of the MOX fuel rod 2a in the central part of the fuel assembly is formed to the outside diameter D larger than the outside diameter C of the pellet 9b of the UO
2 fuel rod 2b in the outer periopheral part of the fuel assembly. The heat transfer coefft. of the spacing between the pellet and the cladding pipe is improved by decreasing the spacing between the pellet 9a and the cladding pipe 10a, by which the surface temp. of the pellet 9a is lowered. The max. temp. of the pellet 9a is finally lowered and the amt. of the gaseous FP to be released is decreased and the fuel performance of the MOX fuel rod is improved.
