In this study, we introduce TARS, a neutron transport code based on the discrete-ordinates
discontinuous finite element (SN-DFEM) method, which tackles existing challenges in the …

Reactor safety analyses require high-fidelity numerical solutions of transient neutron
transport problems. A predictor–corrector quasi-static (PCQS) method based on the Monte …

A polynomial expansion for cross sections has been introduced in the 3D Method Of
