Besides the electricity generation and hydrogen production, HTGRs have many advantages for thermal neutron irradiation applications such as stable operation in longterm, large space available for irradiation target, and high thermal neutron economy. This study summarized the feasibility of new irradiation applications at the HTGRs including neutron transmutation doping silicon and I-125 productions. The HTTR located in Japan was used as a reference HTGR in this study. Calculation results show that HTTR could irradiate about 40 tons of doped Si particles per year for fabrication of spherical silicon solar cell. Besides, the HTTR could also produce about 1.8x105 GBq in a year of I-125, comparing to 3.0x103 GBq of total I-125 supplied in Japan in 2016.
