The Nagoya University Accelerator driven Neutron Source (NUANS) are now constructing at main campus of Nagoya University. The electrostatic accelerator is used with the maximum proton energy and power of 2.8MeV, 15mA(42kW) respectively. Two neutron beam lines are planned at NUANS. The first beam line is dedicated to BNCT. The second beam line is designed for research and development of neutron devices and neutron imaging. The neutrons used for the 2nd beam line are generated by using the (p, n) reaction of beryllium. We designed a compact target station for the 2nd beam line with the dimension of 90cm×90cm×95cm by using radiation shielding simulation. We considered neutron beam extraction with the cross section of 10cm×10cm for radiography at the 2nd beam line. The neutron flux is expected to be about 104n cm-2s-1 with the energy less than 0.1 eV at the position of 2m from the neutron source. We also calculated the proton beam transport from the exit of the accelerator to the neutron production target of the 2nd beam line.
