In the traditional two-step method, the homogenization group constants of the fuel assembly are calculated using the assumption of reflective boundary conditions. In the hybrid two-step method used in ...

Based on the work of Shu [SIAM J. Sei. Stat. Comput, 9 (1988), pp. 1073-1084], we construct a class of high order multi-step temporal discretization procedure for finite volume Hermite weighted ...
