摘要
A new challenge to the existing pellet fuelling technique for the International Thermonuclear Experimental Reactor (ITER) has been discussed by computing ablation rate using Kuteev lentil model with considering the kinetic effects. Numerical integral results show the existing pellet injection technique will be difficult to meet the deep fuelling requirement for the reactor relevant plasma of ITER. As high as a pressure of 254 MPa should be applied to the pellet accelerator of 2-meters long single stage pneumatic gun,
