CRITICALITY CALCULATIONS OF PROSPERO REACTOR

This paper demonstrates the ability, effectiveness and efficiency of the state-of-the-art AMR Deterministic code STYX to solve geometrically complex transport problems using its recently developed 3D parallel version. To do so, a CEA experimental reactor, named Prospero, mainly used for testing radiation shielding of electronic components (Zyromski et al, 1991-99), is modeled. Comparisons, against results from experiments, from the Monte Carlo Code MCNP (Briesmeister, 1997) and even from STYX 2D, are provided.
