摘要： A core of a nuclear reactor wherein the core is provided with a new fuel part 11 at which new fuel is loaded and a burning part 12 where the fuel burns, plutonium which is produced from uranium fissions to generate output, and the burning part 12 moves from the beginning to end of the burning cycle, wherein when dividing the core, which is substantially circular when viewed by a plan view, into a center part and a peripheral part, the new fuel part 11 is formed so that the weight of uranium per unit volume at the center part becomes smaller than the weight of uranium per unit volume at the peripheral part.

摘要： An advanced initial core fuel configuration is for improving the fuel management efficiency and thus economics for a nuclear reactor. A method of implementing such an initial core involves providing a plurality of fuel assemblies having different average enrichments of uranium 235 and arranging the fuel assemblies in an initial core configuration structured to emulate a known equilibrium reload cycle core at least in terms of spatial reactivity distribution. The resulting average enrichment within the initial core ranges from below about 1.0 percent weight of uranium 235 to about 5.0 percent weight of uranium 235. An advanced lattice design is also disclosed.

摘要： A nuclear reactor comprises a fuel rod into which nuclear fuel is enclosed and a control rod that controls nuclear reactions of the nuclear fuel. A concentration of a neutron absorber in a primary coolant at a full power operation of the nuclear reactor, when an operation of the nuclear reactor is started, is set equal to or lower than a value that is obtained by adding a predetermined value to a value obtained by subtracting a concentration of the neutron absorber that is required for maintaining a cold shutdown state of the nuclear reactor when an operation of the nuclear reactor is started from a concentration of the neutron absorber that is required for maintaining cold shutdown of the nuclear reactor when an operation of the nuclear reactor is completed.
