Abstract

Highlights: TaSNAM 2.0 is developed to solve 3D neutronics problem based on FVM. The neutron parameters are obtained from the pre-established neutron parameters library. A three-dimensional steady-state simulation of the whole core in AP1000 was completed. Abstract: The Nuclear Thermal-hydraulic Laboratory (NutheL) at Xi'an Jiaotong University developed a Temporal and Spatial Neutronics Analysis Module (TaSNAM) based on the User Defined Function (UDF) and User Define Scalar (UDS) in Fluent. The neutron diffusion equations were solved based on the Finite volume method (FVM). In this paper, the TaSNAM is extended the original function to solve 3D problems and obtain neutron parameters based on the neutron parameters library, and improved to TaSNAM 2.0. The 3D-IAEA benchmark problem was selected and simulated to validate. The calculated results show good agreement with the reference values and the difference from the reference value of keff is 40pcm. A three-dimensional steady-state simulation of the whole core in AP1000 was completed employing the TaSNAM 2.0. The calculated results of important parameters agree well with the design values and the detailed three dimensional distributions of neutron flux and power were achieved.
