Abstract: In this present analysis, the numerical simulation methods are applied to calculate the solution for Stochastic Neutron Point Kinetic Equations (SNPKE) with pulse reactivity in dynamical system of a nuclear reactor. The resulting systems of differential equations are solved for each time step-size. Using experimental data, the methods are investigated with pulse reactivity. The computational results designate that these numerical approximation methods are straightforward, effective and easy for solving stochastic point kinetic equations.
