Solution of 3D multigroup, linearly anisotropic scattering, criticality problems by the AN boundary-element response-matrix method

► A multigroup neutron transport An code (BERM-AN) is presented. ► A rigorous treatment of the linearly anisotropic scattering is taken into account. ► A response matrix solution procedure coupled to the boundary element method is used. ► Numerical results show that the BERM-AN code is accurate, efficient and robust.
