SAS4 - Control Module

SAS4 is a control module that allows calculation of radiation doses exterior to a transport/storage cask via a three-dimensional Monte Carlo analysis. The sequence execution path includes BONAMI, NITAWL-II, and XSDRNPM (if lattice cell geometry is specified) for cross-section processing; XSDRNPM for evaluation of the adjoint flux used by the sequence for automatic generation of Monte Carlo biasing parameters; and MORSE-SGC for the radiation transport and dose calculation.
