“…The effect of fuelling depth on particle confinement was studied in Refs. [11][12][13] with the experimental data on Japan Atomic Energy Research Institute Tokamak-60 Upgrade (JT-60U) [14] . However, since the macroscopic parameters of JT-60U are far from ITER, the studies above cannot demonstrate the situations in a fusion reactor with long pulse burning plasma; a detailed study on the effect of fuelling depth on the particle confinement and fusion performance of a fusion reactor is still lacking.…”

The fusion performance and particle confinement of an international thermonuclear experimental reactor (ITER)-like fusion device have been modeled by numerically solving the energy transport equation and the particle transport equation. The effect of fuelling depth has been investigated. The plasma is primarily heated by the fusion produced alpha particles and the loss process of particles and energy in the scrape-off layer has been taken into account. To study the effect of fuelling depth on fusion performance, the ITERH-98P(y,2) scaling law has been used to evaluate the transport coefficients. It is shown that the particle confinement and fusion performance are significantly dependent on the fuelling depth. Deviation of 10% of the minor radius on fuelling depth can make the particle confinement change by ∼ 61% and the fusion performance change by ∼ 108%. The enhancement of fusion performance is due to the better particle confinement induced by deeper particle fuelling.
