Method for joint configuration of nuclear power plant fuel

摘要

A method for joint configuration of nuclear power plant fuel includes the following steps: (S1) for at least one operating unit, based on an equilibrium cycle or transition cycle reactor core design, at least one new fuel element is added to at least one operating unit; (S2) after running a combustion cycle, and on basis of the new fuel elements in step (S1), more first spent fuel elements are obtained from the at least one operating unit than are obtained from the equilibrium cycle or transition cycle reactor core design, and said first spent fuel elements are kept in reserve; (S3) for at least one new starting unit, a scheduled number of new fuel elements, as well as the first spent fuel elements obtained for reserve in step (S2), are set in the first reactor cores of at least one new starting unit.

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.
