description Important progress in the development of high-temperature superconductors (HTSC) of the second group made it possible to design the quasi-stationary tokamak with reactor technologies (TRT) with the high magnetic field ( B t0 = 8 T). The high magnetic field will ensure the achievement of plasma fusion regimes in the tokamak with the fusion energy gain Q > 1 at the considerably reduced size of the facility ( R 0 = 2.15 m, a = 0.57 m), and, consequently, at its reduced cost. TRT will be capable of operating in the quasi-stationary regimes (≥100 s) with hydrogen, helium, and deuterium plasmas (with the densities n e of up to 2 × 10 20 m –3 ) and in the regimes with short (duration Δ t < 10 s) deuterium–tritium plasma shots with the fusion energy gain Q > 1 limited by the radiation heating of toroidal coils. TRT is being designed as a plasma prototype for both the pure fusion reactor and the fusion neutron source for the hybrid (fusion–fission) reactor. The TRT missions are the development of the key fusion technologies and their integration in one facility. These technologies are as follows: the HTSC electromagnetic system operating at the extremely high magnetic fields; the metal and liquid-metal (lithium) first wall and innovative divertor; the unique advanced systems for the auxiliary plasma heating and non-inductive current drive, including the systems for atomic beam injection with energy of 0.5 MeV and power of several tens of megawatts, the electron cyclotron heating system based on the megawatt-power gyrotrons with a frequency of 230 GHz and a total power of ~10 MW, and the ion cyclotron heating system at frequencies of 60–80 MHz with a power of several megawatts; the tritium fuel cycle; the remote control technologies; the technologies for diagnostics capable of operating under the fusion reactor conditions; the technologies for maintaining quasi-stationary plasma discharges; and the technologies for the tokamak operation in the fusion ignition regime, in which the heating by alpha particles is the dominant heating mechanism at the axis of the plasma column, in the deuterium–tritium experiments limited by the radiation heating of the toroidal coils. The results are presented from the conceptual design of the basic TRT components, as well as the expected characteristics of its operation. It is shown that TRT has a wide window of working parameters suitable for studying the reactor operating regimes. The high magnetic field provides the necessary margin

The advanced systems for the auxiliary heating and current drive will make it possible to implement both the pulsed and stationary regimes of the reactor operation. Calculations of the TRT discharge scenarios show that, for the DT mixture with equal content of components, the long discharges (with duration exceeding 100 s) can be realized with a neutron flux of more than 0.5 MW/m 2 onto the wall, as well as the stationary discharges with a flux of approximately 0.2 MW/m 2 . Thus, TRT can be a real prototype of the fusion neutron source for the hybrid reactor.</description><identifier>ISSN: 1063-780X</identifier><identifier>EISSN: 1562-6938</identifier><identifier>DOI: 10.1134/S1063780X21110192</identifier><language>eng</language><publisher>Moscow: Pleiades Publishing</publisher><subject>Alpha particles ; Alpha rays ; Atomic ; Atomic beams ; Beam injection ; Control stability ; Cyclotrons ; Deuterium ; Discharge ; Electron cyclotron heating ; Fuel cycles ; High temperature superconductors ; Liquid metals ; Lithium ; Magnetic fields ; Mathematical analysis ; Missions ; Molecular ; Neutron flux ; Nuclear fuels ; Optical and Plasma Physics ; Physics ; Physics and Astronomy ; Plasma ; Plasma heating ; Plasmas (physics) ; Prototypes ; Radiant heating ; Radiation ; Remote control ; Tokamak devices ; Tokamaks ; Tritium</subject><ispartof>Plasma physics reports, 2021-11, Vol.47 (11), p.1092-1106</ispartof><rights>Pleiades Publishing, Ltd. 2021.
