Abstract The results of full-scale numerical experiments of a hybrid thorium-containing fuel cell facility operating in a close-to-critical state due to a controlled source of fusion neutrons are discussed in this work. The facility under study was a complex consisting of two blocks. The first block was based on the concept of a high-temperature gas-cooled thorium reactor core. The second block was an axially symmetrical extended plasma generator of additional neutrons that was placed in the near-axial zone of the facility blanket. The calculated models of the blanket and the plasma generator of D-T neutrons created within the work allowed for research of the neutronic parameters of the facility in stationary and pulse-periodic operation modes. This research will make it possible to construct a safe facility and investigate the properties of thorium fuel, which can be continuously used in the epithermal spectrum of the considered hybrid fusion–fission reactor.

维持由 DT Fusion 中子通量控制的混合反应堆钍燃料堆芯的接近临界状态

摘要 本文讨论了由于聚变中子源受控而在接近临界状态下运行的混合含钍燃料电池设施的全尺寸数值实验结果。所研究的设施是一个由两个街区组成的综合设施。第一个区块基于高温气冷钍反应堆堆芯的概念。第二个区块是一个轴对称的扩展等离子体发生器，它包含额外的中子，放置在设施毯的近轴区。在工作中创建的毯子和 DT 中子等离子体发生器的计算模型允许在固定和脉冲周期操作模式下研究设施的中子参数。
