METHOD AND SYSTEM FOR GENERATING NUCLEAR REACTOR CORE LOADING DISTRIBUTION Russian patent published in 2018 - IPC G21C19/18 

FIELD: nuclear physics and equipment.

SUBSTANCE: invention relates to the determination of nuclear fuel load distribution for a nuclear reactor core and, in particular, to determining fuel loading distribution for a beginning-of-cycle (BOC) nuclear reactor core. Generation of a nuclear core loading distribution includes receiving a reactor core parameter distribution associated with a state of a reference nuclear reactor core, generating an initial fuel loading distribution for a simulated beginning-of-cycle (BOC) nuclear reactor core, selecting an initial set of positions for a set of regions within the simulated BOC core, generating an initial set of fuel design parameter values, calculating a reactor core parameter distribution of the simulated BOC core utilising the generated initial set of fuel design parameter values and generating a loading distribution by performing a perturbation process on the set of regions of the simulated BOC core to determine a subsequent set of positions for the set of regions within the simulated BOC core.

EFFECT: reducing the need for large expenditures of time for transition from the state of the beginning of life to the equilibrium state.
