The IHNI is designed with low-enrichment 235U (LEU) for Boron Neutron Capture Therapy (BNCT) based on Miniature Neutron Source Reactor (MNSR). The IHNI, operated with thermal power 30kW, is an under-moderated reactor of pool-tank type, and UO2 as fuel, light water as coolant and moderator, and metallic beryllium as reflector. The paper gives the physics and safety characteristics of IHNI. The physics characteristics include those parameters of the criticality and the beam port used for BNCT. The safety characteristics compare the safety parameters between reactor core of LEU and HEU. The result shows that LEU could meet the requirements of criticality and flux at exit of each beam. Furthermore, the better safety characteristics could approach by adopting the LEU in comparison with HEU.
