Numerical simulation based on Haar wavelet operational method to solve neutron point kinetics equation involving sinusoidal and pulse reactivity

In this article, the wavelet operational method based on Haar wavelet is introduced to obtain the numerical approximate solution of neutron point kinetic equation appeared in nuclear reactor with time-dependent and independent reactivity function. The present method has been applied gracefully to solve stiff point kinetics equations using sinusoidal and pulse reactivities. Haar wavelet operational method (HWOM) has turned out as an accurate computational technique for many applications in science and engineering. The accuracy of the obtained results is truly fine even if the number of collocation points is small. By increasing the number of collocation points, the error of the approximation solution decreases rapidly. The proposed numerical approximate technique is very useful for solving the group of six-delayed neutron point kinetic equations involving sinusoidal and pulse reactivity functions.
