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.

使用 OpenMC Monte Carlo 代码对 BAEC TRIGA 反应堆 (BTRR) 作为 BNCT 中子源的技术可行性研究

摘要 癌症治疗是全球医学领域的一项具有挑战性的任务。大多数情况下的治疗程序往往有局限性和有害的副作用。硼中子俘获疗法 (BNCT) 是一种癌症治疗方法，发现它在某些形式的肿瘤细胞中毒性更小且更有效。BNCT 需要中子束，而研究堆是其中最可靠的来源。这项研究是关于孟加拉国原子能委员会 TRIGA 研究反应堆 (BTRR) 用作 BNCT 中子源的技术可行性。BTRR 反应堆有三个目前未使用的辐照点（2 个束管 (BT) 和一个热柱）。这项研究检查了 BNCT 处理中子束要求（超热束）在反应堆不同外部辐照位置的技术可行性。Monte Carlo 仿真工具包 OpenMC 用于进行反应器模型和通量计算。结果发现，热柱将是安置患者进行治疗的最佳场所。1.0E+09 的超热通量大约在热柱石墨的一半处可用。
