A small tokamak-based fusion reactor can be attractive for actinide waste transmutation. Equilibrium concentrations of transuranium isotopes were estimated in a molten-salt based fusion transmutation reactor. Nuclear performance parameters were derived for two types of fusion-driven transmutation reactors: Pu-assisted and minor actinidesonly systems. The minor actinide-only burning system appea...

The development strategy of nuclear fusion energy in the Korea National Basic Plan for the Development of Fusion Energy consists of several major programs. These are shown in Fig. 1, and include KSTAR for the study of a long-pulse, advanced tokamak operation, ITER for a burning plasma experiment, the DEMO reactor for the demonstration of producing net electricity from a fusion reactor, and a co...

This report presents a conceptual design of the magnet systems for an advanced tokamak fusion reactor (ARIES-AT). The main focus of the paper is to anticipate and extrapolate the current state-of-the-art in high temperature superconductors and coil design, and apply them to an advanced commercial fusion reactor concept. The current design point is described and supported with a preliminary stru...

Social acceptance of fusion reactors depends largely on their economic viability. To investigate this issue, we estimate and compare the cost of electricity (COE) among D-T, D-3He, and D-D fusion reactors. Three types of confinement systems are evaluated: the tokamak reactor (TR), the spherical tokamak reactor (STR), and helical reactor (HR). For each reactor type, COE parameter surveys are per...

The fusion-fission hybrid system has the potential attractiveness of good safety performances and plenty of fuel compared to the fission reactor system and also easing the requirement of fusion plasma technology. It is a practical path to the early fusion application for energy production. In this paper, a fusion-driven subcritical reactor for energy multiplier, named FDS-EM, is proposed. It ca...

An important milestone on the Fast Track path to Fusion Power is to demonstrate reliable commercial application of Fusion as soon as possible. Many applications of fusion, other than electricity production, have already been studied in some depth for ITER class facilities. We show that these applications might be usefully realized on a small scale, in a Multi-Functional Compact Tokamak Reactor ...

In previous work [1] a standard feedforward artificial neural network (ANN) with sigmoidal activation functions was used to demonstrate the capabilities of ANN for the stabilization of burn conditions, at nearly ignited conditions, of a thermonuclear reactor operating in the low temperature region. In this region, the nominal operating point of the fusion reactor is inherently unstable. The pur...
