Abstract

Continuous energy Monte Carlo tools in SCALE are commonly used in criticality safety calculations, but new developments in SCALE 6.2 provide enhanced continuous-energy capabilities as well in sensitivity and uncertainty, depletion, and criticality accident alarm system (CAAS) analyses. Recent improvements in the continuous-energy data generated by the AMPX code system and significant advancements in the continuous-energy treatment in the KENO Monte Carlo eigenvalue codes facilitate the use of SCALE Monte Carlo codes to model geometrically complex systems with enhanced solution fidelity. The addition of continuous-energy treatment to the Monaco fixed-source Monte Carlo code, which can be used with automatic variance reduction in the hybrid MAVRIC sequence, provides increased solution fidelity for shielding applications and CAAS modeling. In addition, the Monte Carlo depletion capability in SCALE has been extended from multigroup to continuous energy. This paper describes some of the advancements in continuous-energy Monte Carlo codes within the SCALE code system.
