Abstract:
ARES is a multi-group of anisotropic scattering transport code based on discrete ordinates method. It is primarily used for the nuclear device’s shielding calculation and analysis in the case of one-dimension, two-dimension and three-dimension. A variety of options allow spatial variables to be dispersed by the diamond difference, theta weight or discontinuous finite element method. The quadrature set can be adaptively selected. Variety of boundary conditions and sources can be treated. First collision source method was used to eliminate or mitigate the ray effect. The acceleration module consists of diffusion synthetic acceleration (DSA), angular multigrid and MPI parallel of domain decomposition. The preliminary verification for part module of the shielding code has been done by benchmark and reference code.
