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 reduce the cost of production and to increase the Pu charge quantity per fuel assembly by disposing one or three pieces of uranium U fuel rods without contg. plutonium Pu in the corner parts facing control rods in the fuel assembly.
CONSTITUTION: One or three pieces of the fuel rods U loaded with the pellets contg. UO
2 and without contg. PuO
2 are disposed in the corner parts facing the control rods 11 in the fresh fuel assembly 12 of 0Gwd/t burnup. The fuel rods (the degree of Pu enrichment is higher as the number is smaller) contg. the MOX (uranium/plutonium mixed oxide) loaded with the pellets formed by mixing the UO
2 and the PuO
2 are usable for the fuel rods 1 to 4 exclusive of the fuel rods G contg. the UO
2 and Gd
2 O
3 in this way and, therefore, the charge quantity of the MOX fuel is increased. Since the kinds of the degree of the Pu enrichment in the MOX fuel assembly are decreased, the cost of producing the fuel assemblies is reduced.
