A new intranuclear cascade model describing fragment productions (INC-FRG) has been developed. The fragment production model implemented in INC-FRG is based on a combination of the surface coalescence and knockout models. The current INC-FRG provides not only information of neutrons and protons but also that of fragments (clusters) up to 4 He. Results of our calculation with INC-FRG are presented and compared with experimental data. As examples, comparisons for some proton induced reactions are shown in this article. The calculated fragment spectra considerably agree with experimental results. It is concluded that the cluster knockout contribution plays a key role in the fragment production spectra especially at forward angles.
