Abstract

This manuscript focuses on the UNIC code, which is being developed to provide high fidelity solutions of the neutron transport equation in the fast reactor program of the Global Nuclear Energy Partnership. At present, we have developed three solvers for the neutron transport code: PN2ND, SN2ND, and MOCFE. PN2ND is based upon the second-order even-parity transport equation where spherical harmonics are utilized for the angular approximation. SN2ND is also based upon the second-order even-parity transport equation where a discrete ordinates approximation is utilized for the angular approximation. This manuscript discusses the motivations behind creating the PN2ND and SN2ND solvers along with their targeted applications. We also discuss the current performance of the two solvers and present some benchmark results. MOCFE is the first-order method of characteristics solver, which is focused on providing the capability of treating the explicit geometrical problems - a long term goal of this project. We give a summary of the status of this solver and have included a companion paper to provide more details.
