针对低展长比托卡马克堆的几何特性，提出了一种以中子屏蔽为主的舱内结构和在舱外包层中产生足够氚的基本中子电子学策略。研究了最佳板内屏蔽层的设计，并估计了使超导磁体上的中子通量足够低所需的厚度。此外，在先进聚变材料的基础上，研究了外包层的设计，以获得足够大的氚增殖比（TBR）。
Considering the geometrical characteristics of tokamak reactors with low aspect ratio, a basic neutronics strategy was derived to construct the inboard structure mainly for neutron shielding and produce enough tritium in the outboard blanket. The designs for optimal inboard shield were surveyed and necessary thickness was estimated to make the neutron flux low enough on the super-conducting magnet. In addition, the outer blanket designs were studied to attain the tritium breeding ratio (TBR) large enough for a self-sustaining fusion reactor on the basis of the advanced fusion reactor materials.
