Abstract

The purpose of this study is to design an epithermal neutron beam for neutron capture therapy (NCT) using the thermal column of Tsing Hua Open-Pool Reactor (THOR) which is currently operated at full power of 1 MW with potential to be upgraded to 3 MW in the near future. In the initial stage of this project, beam design calculations are performed using the three-dimensional discrete-ordinate transport code TORT together with neutron/photon coupled cross section library BUGLE-80. The calculated results indicate that by replacing the removable portion of graphite blocks in the thermal column with properly designed filter/moderator, epithermal neutron flux can reach 109 n/cm2/s with fast neutron dose and gamma ray dose per epithermal neutron less than 10−10 cGy cm2/n. It is believed that neutron beam suitable for NCT purpose can be obtained.
