[0017] Based on the technology disclosed in this document, when operating a magnetic confinement fusion device such as a tokamak, pellets can be injected into thermal fusion plasma to alleviate undesired plasma rupture. However, the injected pellets tend to evaporate quickly due to the heating caused by the thermal fusion plasma. This evaporation can limit the penetration depth of the injected pellets into the thermal fusion plasma. The penetration of pellets into the core of the confined plasma before complete evaporation can alleviate undesired plasma rupture. The interaction of the plasma and the melted material of the pellets enables the plasma to radiate its thermal energy, thereby spreading it over a wide area, instead of allowing uncontrolled thermal energy loss to the plasma surrounding the components facing the fusion device . The plasma can be confined by nested magnetic flux surfaces, but when these surfaces are destroyed during plasma rupture, the thermal energy o...
