摘要
Abstract
In order to analyze the effect of the proton energy on the number of neutrons produced per source proton and the neutron yield spectra and values of neutron leakage distributions per proton over the cylindrical metal target surface in Accelerator Driven System (ADS),MCNPX are used to calculate them under different proton beam energy,and the results are compared with the results of the international organization institutions.The number of neutrons produced per source proton of tungsten target is larger but the tally of neutron leakage is smaller than lead target.Combining the MCNPX with MCNP5,the efficiency of the spallation neutions relative to fission neutrons for a subcritical benchmark system was calculated.关键词
