基于对球形环托卡马克(ST)聚变堆的研究,提出了ST聚变-嬗变堆的设计概念。运用一维输运燃耗计算程序BISON3.0进行了优化设计,确定了适合嬗变少额锕系核素MA(Minor Actinides)的ST堆芯等离子体参数、包层结构及合适的换料周期。在此基础上,运用二维中子学程序TWODANT进行了二维中子输运计算。利用TWODANT给出的中子通量,运用一维放射性计算程序FDKR进行了燃耗计算,并给出了有关的计算结果。
Based on the study of the toroidal ring Tokamak (ST) fusion reactor, the design concept of ST fusion-transmutation reactor is proposed. The optimized design of BISON3.0, a one-dimensional transport and burnup calculation program, was used to determine the ST core plasma parameters, cladding structure and suitable refueling cycle for Minor Actinides. On this basis, two-dimensional neutron transport calculation is carried out using two-dimensional neutron program TWODANT. Based on the neutron flux given by TWODANT, a one-dimensional radiometric calculation program FDKR was used to calculate the fuel consumption, and the related calculation results were given.
