Predicting the behavior of neutrons with exascale computation
Predicting the behavior of neutrons has been of fundamental importance for the nuclear security enterprise since the very beginning. Though we have come a long way from the days of using a series of wheels to simulate the movement in neutrons in a system, as Fermi did, Monte Carlo simulations that use random numbers to estimate the behavior of neutrons in a nuclear system still are a critical technology in the nuclear analytical toolkit.
