Fuel assembly of reactor
专利汇可以提供Fuel assembly of reactor专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve economics and also to facilitate control of fuel rods by decreasing the kinds of MOX fuel rods being different in the degree of Pu enrichment without changing the amount of plutonium charged on a fuel assembly as a whole.
CONSTITUTION: In an MOX fuel assembly 10 for a D lattice core, uranium fuel rods B are used as fuel rods at coordinates 1, 1, coordinates 1, 2, coordinates 2, 1, coordinates (n), 1 and coordinates 1, (n), and MOX rods A are used as fuel rods 12 other than the rods B, except the rods 12 containing burnable poison such as gadolinia. As for the MOX rods A, in this case, only three kinds of rods 12 being different in the degree of Pu enrichment need to be used. Thereby the degree of the Pu enrichment of the MOX rods A can be reduced and the rods B equivalent thereto are used for the reduction. The reduction in the amount of plutonium charged for one body of the assembly can be made small, e.g. 5% or below. This is because the number of rods replaced by the rods A is small and, consequently, the degree of the Pu enrichment at the positions thereof is low.
