综述了仿星器-镜裂变-聚变混合概念的发展。该混合体由聚变中子源和强大的亚临界快裂变反应堆堆芯组成。其目的是使乏核燃料嬗变并安全生产裂变能。在聚变部分，中子在氘氚（D-T）等离子体中产生，并被磁约束在一个带有嵌入式磁镜的仿星器型系统中。基于动力学计算，分析了该体系的能量平衡。用MCNPX程序进行了中子计算，并对反应堆部分进行了初步设计。计算了反应堆不同外部的中子出流率。对仿星镜装置模型中的磁场结构进行了数值模拟，这是通过关闭Uragan-2 M扭转加速器中的一个或两个环向场线圈来实现的。计算预测在一定条件下存在封闭的磁表面。分析了快粒子在这种磁阱中的禁闭。
The development of a stellarator–mirror fission–fusion hybrid concept is reviewed. The hybrid comprises of a fusion neutron source and a powerful sub-critical fast fission reactor core. The aim is the transmutation of spent nuclear fuel and safe fission energy production. In its fusion part, neutrons are generated in deuterium–tritium (D–T) plasma, confined magnetically in a stellarator-type system with an embedded magnetic mirror. Based on kinetic calculations, the energy balance for such a system is analyzed. Neutron calculations have been performed with the MCNPX code, and the principal design of the reactor part is developed. Neutron outflux at different outer parts of the reactor is calculated. Numerical simulations have been performed on the structure of a magnetic field in a model of the stellarator–mirror device, and that is achieved by switching off one or two coils of toroidal field in the Uragan-2M torsatron. The calculations predict the existence of closed magnetic surfaces under certain conditions. The confinement of fast particles in such a magnetic trap is analyzed.
