An irradiation-experimental equipment for 12in neutron transmutation doping silicon (NTD-Si) was designed conceptually by using MCNP5 in order to improve the neutron flux distribution of the radial direction. As a result of the calculations, the neutron absorption reaction ratio of the circumference to the center could be limited within 1.09 using a thermal neutron filter that covers the surface of the silicon ingot. The uniformity of the (30)Si neutron absorption was less than 5.3%.
