Title:
TRANSIENT ANALYSIS METHOD FOR NUCLEAR POWER PLANT ACCIDENT CAUSING PELLET-CLADDING INTERACTION
Document Type and Number:
WIPO Patent Application WO/2024/093077
Kind Code:
A1
Abstract:
A transient analysis method for a nuclear power plant accident causing pellet-cladding interaction. The method comprises: acquiring the same xenon strategy for a nuclear thermal system program and a reactor core computing program (S100); acquiring an initial-moment axial power deviation of the nuclear thermal system program and an initial-moment axial power deviation of the reactor core computing program (S200); when the initial-moment axial power deviation of the reactor core computing program is consistent with the initial-moment axial power deviation of the nuclear thermal system program, acquiring a neutronics parameter of the reactor core computing program and a neutronics parameter of the nuclear thermal system program (S300); correcting the neutronics parameter of the nuclear thermal system program to be consistent with the neutronics parameter of the reactor core computing program (S400); according to the corrected neutronics parameter of the nuclear thermal system program, acquiring a boundary condition of a transient accident process that causes pellet-cladding interaction (S500); and obtaining the power distribution of the reactor core computing program in the transient accident process (S600).
