A numerical approach based on Haar wavelet operational method to solve neutron point kinetics equation involving imposed reactivity insertions

This method is applied to different types of reactivity in order to check the validity of the proposed method. Moreover, the obtained approximate results have been also compared with other available numerical results. It manifests that the results obtained by the HWOM are in good agreement with other available results even for large time range and it is certainly simpler than other methods in open literature.
