Implications of Particle Recycling on Core Plasma Performance in Advanced Aneutronic Fuel Spherical Tokamak Reactor

A volume average particle and energy equations are applied to study the effects of particle recycling on plasma parameters for aneutronic deuterium and helium-3 (D- \({^3}\) ${}^3$ He) fuel cycle. The presented simulation study shows the core plasma performance while with and without recycling particle are utilized. It is found that the recycled particle has a significant impact on the D- \({^3}\) ${}^3$ He fuel parameters. Finally, with the aid of the operation path method on the n \(_e\) ${}_e$ -T plane on the background of the plasma operating contour (POPCON) line, the plasma behavior for both cases is compared.
