# Stochastic Neutron Point Kinetics

A system of stochastic differential equations can accurately model the random behavior of the neutron density and the precursor concentrations in a point reactor. Due to the issue of stiffness, numerical implementation may be challenging. This research focused on studying the influence of stochastic fluctuations upon the results of the neutron point kinetics equations, and to find an approach to obtain a nonstiff solution for the stochastic neutron point kinetics equations.
