HENDL2.0, the latest version of the hybrid evaluated nuclear data library, wasdeveloped based upon some evaluated data from FENDL2.1 and ENDF/B-Ⅶ. To qualify andvalidate the working library, an integral test for the neutron production data of HENDL2.0 wasperformed with a series of existing spherical shell benchmark experiments (such as V, Be, Fe, Pb,Cr, Mn, Cu, A1, Si, Co, Zr, Nb, Mo, W and Ti). These experiments were simulated numericallyusing HENDL2.0/MG and a home-developed code VisualBUS. Calculations were conducted withboth FENDL2.1/MG and FENDL2.1/MC, which are based on a continuous-energy Monte CarloCode MCNP/4C. By comparison and analysis of the neutron leakage spectra and the integral test,benchmark results of neutron production data are presented in this paper.
