The damage energy cross sections and displacement cross sections of W, SS316 and Al-6061, which will be used in the CSNS (China Spalllation Neutron Source) target station, were calculated with the high energy transport code MCNPX 2.5.0. The DPA (Displacement Per Atom) distributions were also calculated and anlyzed for the main components in the CSNS target station, such as the W target, the target vessel, the moderators and reflector vessels. Based on the DPA caused by neutrons and protons, the lifetime of these components were estimated. The influence of the proton beam profile on the peak value of DPA for W target and target vessel were also presented. These calculations and analyses are very important for the under going CSNS project.
