description	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, effective point reactor kinetic parameters, which can be applied to unstructured grids, were calculated based on the Galerkin 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 calculated. Finally, the effective point reactor kinetic parameters of the Tehran research reactor were obtained by comprehensively processing the steady-state neutronic parameters.
