Fuel loading of boiling nuclear reactor
专利汇可以提供Fuel loading of boiling nuclear reactor专利检索，专利查询，专利分析的服务。并且PURPOSE: To decrease an output power density and to intend to get an expanded flexibility of a control rod operation by loading uranium dioxide fuels preferentially, to control cells constituted with a mixture of uranium dioxide fuel and plutonium-rich MOX fuel.
CONSTITUTION: Control cells CC, which are painted black in the figure, are constituted by arranging four fuel assemblies around control rods each for power regulation and reactivity regulation. As a fuel to be loaded at the control cell CC, an UO
2 fuel of comparatively low reactivity, is used. Comparing infinite multiplication constants in a burning-up region on the control cell CC, the constant of the UO
2 fuel is lower than that of the MOX fuel of the same burning-up extent. Accordingly, an output power density of the control cell CC becomes 2 to 6% lower than a comparison example, at an end of a fuel burning-up. Also, as a control rod value of the UO
2 fuel is comparatively larger than that of the MOX fuel on the whole fuels in general, an insertion extent of the control rod can be decreased compared to the comparison example. Therefore, a neutron exposure to the control rod can be decreased.
