Abstract:
1. A method for configuring nuclear power plant fuel elements/assemblies jointly, comprising steps for configuring fuel elements/assemblies jointly between at least one operating unit and at least one new starting unit with a first reactor core: (S1) adding at least one new fuel element/assembly to the at least one operating unit according to an equilibrium cycle or transition cycle reactor core configuration design; (S2) after running a fuel cycle, obtaining spent fuel elements/assemblies having burned once from the at least one operating unit based on an amount of added new fuel elements/assemblies loaded in step (S1), and keeping said spent fuel elements/assemblies for further use, wherein, an amount of the spent fuel elements/assemblies having burned once from the at least one operating unit is larger than that of the spent fuel elements/assemblies obtained in the equilibrium cycle or transition cycle reactor core configuration design; (S3) putting a scheduled number of new fuel elements/assemblies, and the spent fuel elements/assemblies having burned once which are obtained from step (S2) in the first reactor cores of the at least one new starting unit.
