VERA-CS VALIDATION OF CRITICAL EXPERIMENTS

VERA is a suite of multiphysics codes which uses MPACT to model neutron transport in light water reactors (LWRs) [1]. In this paper, we validate by modeling critical experiments conducted at the IPEN/MB-01 and B&W facilities. We modeled loading with variety different fuel pins materials placed core. The were two dimensions using an axial buckling term. Default mesh parameters exist for larger reactor cores, convergence study was performed find appropriate smaller reactors. k eff results show consistent bias small standard deviation facility. Overall, that performs well
