提出了基于球形环托卡马克聚变堆FDTR嬗变处置少额锕系核废物MA的设计概念,以及堆芯等离子体参数和嬗变包层的设计框架;完成了系统的嬗变中子学设计与计算。中子学计算由一维输运与燃耗程序BISON和三维蒙特卡罗程序MCNP/4B完成。文中给出了系统的嬗变率、能量增益因子、氚增殖率、MA核素成分随运行时间的变化等结果。对球形环托卡马克聚变堆的关键部件——中心柱的辐照特性及工程可行性也作了初步的计算与分析。
The design concept of the MA based on the spherical ring Tokamak fusion reactor FDTR transmutation, and the design framework of the core plasma parameters and the transmutation cladding were also put forward. The transmutation neutron design and calculation of the system were completed. Neutronics calculations are performed by the one-dimensional transport and burnup program BISON and the three-dimensional Monte Carlo program MCNP / 4B. The results of system transmutation rate, energy gain factor, tritium proliferation rate, MA radionuclide composition with the running time are given. The preliminary calculation and analysis of the irradiation characteristics and feasibility of the central column, the key component of the toroidal ring Tokamak fusion reactor, are also made.
