[1F08] Monte Carlo Criticality Calculation of Random Media with Bounded Fluctuation due to Normal Noise

*Taro Ueki¹ (1. Japan Atomic Energy Agency)

Keywords:normality noise, bounded spatial fluctuation, randomization, Monte Carlo, criticality, Karhunen-Loève expansion

Randomized media are an effective framework for evaluating the uncertainty of Monte Carlo criticality calculation in a material mixture of unknown spatial distribution. This excerpt reports the application of the Karhunen-Loève expansion of superposed Brownian motion to the spatial fluctuation of volume fractions.
