“…In this work, we use a 0-D model of a burning deuterium-tritium plasma that implies particle and energy balance equations. In this model, plasma can be considered as a quasi-neutral set of electrons with the density of n e , hydrogen isotopes density n i , and alpha particle density n α as a reaction product in a fusion reactor at the temperatures of T e and T i respectively [18].…”

In this study, the ignition criteria in the International Thermonuclear Experimental Reactor (ITER) associated with helium concentration is investigated. The main fuels used in this study are deuterium-tritium. Helium as the ash of deuterium-tritium reaction cannot be avoided. In this work, the effects of alpha particle concentration on plasma operation are investigated. The calculations were performed by using zero-dimensional power and particle balance equations. The results of our calculations show that the temporal evolution of alpha particle concentration becomes constant at 0.14. Then, ignition criteria and saddle points have been studied in neτE -T, and Phtτ2E -T planes for different alpha particle concentrations.

“…Consider some estimates of the possible layout of main elements of the system for the version with the following parameters (regime #4): minor radius a = 0.44 m, major radius R = 2.3 m, magnetic field at the magnetic axis B 0 = 5.3 T. The layout of the different zones is shown in figure 7. In the analysis, we take into account the parameters of blanket concepts [1,2,22,[27][28][29][30][31]. Various types of blankets have been proposed for hybrid reactors: water cooled, sodium [2], gas cooled [28], liquid metal [4,30], molten salt [31].…”

Evaluation of the operational parameters for NBI-driven fusion in low-gain tokamaks with two-component plasma

Low gain (Q ~ 1) fusion plasma systems are of interest for concepts of fusion-fission hybrid reactors. Operational regimes of large modern tokamaks are close to Q ≈ 1. Therefore, they can be considered as prototypes of neutron sources for fusion-fission hybrids. Powerful neutral beam injection (NBI) can support the essential population of fast particles compared with the Maxwellial population. In such two-component plasma, fusion reaction rate is higher than for Maxwellian plasma. Increased reaction rate allows the development of relatively small-size and relatively inexpensive neutron sources. Possible operating regimes of the NBIheated tokamak neutron source are discussed. In a relatively compact device, the predictions of physics of two-component fusion plasma have some volatility that causes taking into account variations of the operational parameters. Consequent parameter ranges are studied. The feasibility of regimes with Q ≈ 1 is shown for the relatively small and low-power system. The effect of NBI fraction in total heating power is analyzed.
