[2J05] Development of multi-species material randomization using Monte Carlo solver Solomon

*TARO UEKI1 (1. JAEA)

Keywords:distribution uncertainty, multi-species materials , criticality, randomization, Monte Carlo, Solomon

Randomized Weierstrass function (RWF) is a model specifically designed for the criticality of two material systems under uncertain distribution. It is reported in this excerpt that the RWF has been extended to systems of any number of multi-species materials based on the division of each constituent material and the combinatorial couplings of different materials. A set of numerical results is shown using Monte Carlo solver Solomon.
