Description: Consistent $$P_1SA$$ scheme for acceleration of inner and outer iterations convergence for the neutron and gamma-rays transport equation in one-dimensional geometries: Implementation in code package REACTOR. The construction of the P 1 SA scheme for acceleration of inner and outer iterations convergence consistent with the weighted diamond differencing discrete ordinates multigroup transport equation in one-dimensional geometries is discussed. The scattering anisotropy is operated in the P L -approximation. The outer iterations acceleration technique is described for anisotropic scattering neutron thermalization problems and subcritical fission boundary problems. Some numerical examples are given. The described variant of the P 1 SA algorithm is implemented in the code package REACTOR.
