Abstract

S_N method is wildly used to solve neutron transport equation, but S_N method is very slow with highly anisotropic scattering. In this paper, the modified P_N synthetic acceleration (MPSA) method is used to accelerate S_N method, and applied to the code of ANISN which is internationally used. MPSA method not only can accelerate the computation with low-order of angular flux moments, but also with high-order of angular flux moments. So MPSA method is more efficient than DSA method. Numerical results for the test problems demonstrate that MPSA method is quiet efficient and robust, especially for the problems with highly anisotropic scattering.
