Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

The concept for a plasma shutdown system has been studied for fusion experimental reactors. An impurity pellet injection system is proposed as the plasma shutdown system. The density limit disruption is employed by using impurity pellet injection. The pellet size and its injection velocity are obtained with an evaluation model of the tearing mode and a model of pellet ablation. The main functions of the impurity pellet injection system are checked by the trial manufacturer. The concept for this plasma shutdown system is extended to the International Thermonuclear Experimental Reactor (ITER).
