Abstract
Cancer treatment is a challenging task in the medical field around the world. Most of the cases of the treatment procedures often have limitations and harmful side effects. Boron Neutron Capture Therapy (BNCT) is a method of cancer treatment where it is found to be less toxic and more effective in some form of tumor cells. BNCT requires a neutron beam, and a research reactor is the most reliable source of it. This study is about the technical feasibility of the Bangladesh Atomic Energy Commission TRIGA research reactor (BTRR) used as a neutron source for BNCT. The BTRR reactor has three irradiation sites (2 beam tubes (BTs), and a thermal column) currently unutilized. This study checks the technical feasibility of BNCT treatment neutron beam requirements (epithermal beam) in different external irradiation sites of the reactor. Monte Carlo simulation toolkit OpenMC was used to carry out the reactor model and flux calculation. It was found that the thermal column would be the best place to house the patient for the treatment. An epithermal flux of 1.0E+09 is available about halfway into the thermal column graphite.
