The finite element method based on unstructured mesh has good geometry adaptability. It has been used to solve reactor physics problems, manual description of geometric modeling and meshing makes the current finite element code very complicated. It greatly restricts the application of this method in the numerical calculation of reactor physics. Using the CAD pre-processing software ICEM-CFD, tetrahedral or hexahedral mesh subdivision of 3D core geometry is performed, triangular or quadrilateral mesh subdivision of 2D core geometry is performed, the main code of neutron calculation for nuclear noise analysis based on finite element method is developed. The steady state parameters such as flux, adjoint flux and k_eff/k_eff^* are calculated and tested through benchmark problem, the test results show that the calculation results of the steady state parameters of this code are credible. Finally, the neutron noise spectrum is calculated for the 3D PWR benchmark problem published by IAEA, and the noise distribution under given frequency is given.

Abstract: The finite element method based on unstructured mesh has good geometry adaptability. It has been used to solve reactor physics problems, manual description of geometric modeling and meshing makes the current finite element code very complicated. It greatly restricts the application of this method in the numerical calculation of reactor physics. Using the CAD pre-processing software ICEM-CFD, tetrahedral or hexahedral mesh subdivision of 3D core geometry is performed, triangular or quadrilateral mesh subdivision of 2D core geometry is performed, the main code of neutron calculation for nuclear noise analysis based on finite element method is developed. The steady state parameters such as flux, adjoint flux and k_eff/k_eff^* are calculated and tested through benchmark problem, the test results show that the calculation results of the steady state parameters of this code are credible. Finally, the neutron noise spectrum is calculated for the 3D PWR benchmark problem published by IAEA, and the noise distribution under given frequency is given.
