3He reaction
Published in S. V. Ryzhkov, A. Yu. Chirkov, Alternative Fusion Fuels and Systems, 2018
The parameters of D–3He reactors were compared on the basis of existing magnetic confinement systems: a tokamak, a spherical tokamak, a stellarator, a reversed magnetic configuration, or an elongated compact torus. The most attractive from a technical point of view is FRC (compact toroid (CT), which is due to the simplicity of the linear geometry of the external magnetic field. One of the advantages of the D–3He reactor based on the reversed magnetic configuration is the high density of energy release, which makes it possible to create a relatively compact reactor of the same power as the deuterium–tritium tokamak. A high efficiency of the D–3He reactor based on a spherical tokamak requires extremely high values of the magnetic field for this system. A significant advantage of the spherical tokamak is that the behaviour of the plasma in it obeys the same laws as in the classical tokamak for which the level of research is significantly ahead of all other containment systems. Regimes for efficient energy production are found, comparison of conceptual designs of D–3He reactors based on tokamak and compact torus is given.
Multifunctional Neutronics Calculation Methodology and Program for Nuclear Design and Radiation Safety Evaluation

The FDS series fusion demonstration and commercial reactors include the FDS-II (Refs. 36 and 37), the FDS-III (Ref. 38), the FDS-ST (Ref. 39), and the C-DEMO (Ref. 36) as shown in Fig. 6. The FDS-II is designed to exploit and evaluate the potential of fusion energy for electricity generation based on advanced plasma parameters, which can be extrapolated from the successful operation of ITER. The FDS-III, which can be widely used for hydrogen production, uses a super high–temperature PbLi blanket with an outlet temperature of approximately 1000°C. It has several important features, such as an innovative coolant flow channel design and the use of relatively mature steel as structural material. The spherical tokamak-based fusion reactor FDS-ST is designed with a high energy multiplication factor for economical operation.
