THE MC21 MONTE CARLO TRANSPORT CODE

摘要

MC21 is a new Monte Carlo neutron and photon transport code currently under joint development at the Knolls Atomic Power Laboratory and the Bettis Laboratory. MC21 is the Monte Carlo transport kernel of the broader Common Monte Carlo Design Tool (CMCDT), which is also currently under development The vision for CMCDT is to provide an automated, computer-aided modeling and post-processing environment integrated with a Monte Carlo solver that is optimized for reactor analysis. CMCDT represents a strategy to push the Monte Carlo method beyond its traditional role as a benchmarking tool or "tool of last resort" and into a dominant design role. In the full paper we will give a thorough introduction to MC21 and the related parts of CMCDT. In this summary, we focus on the areas of neutron scattering physics and tallies.
