Precise point reactor kinetic parameters are essential in the study of reactor dynamics. Point reactor kinetic parameters include the effective delayed neutron fraction and prompt neutron lifetime. In this work, effec-tive point reactor kinetic parameters, which can be applied to unstructured grids, were calculated based on the Galer-kin finite element method. First, two-dimensional and three-dimensional benchmarks were used to verify the calculation of steady-state neutronic parameters. Then, the Tehran research reactor core was divided into hexahedral meshes, and the forward flux and adjoint flux were calcu-lated. Finally, the effective point reactor kinetic parameters of the Tehran research reactor were obtained by compre-hensively processing the steady-state neutronic parameters.
