In remarks tied to the UN week, Trump repeated the argument that Europe—and specifically Germany—turned back to traditional fuels after pursuing renewables, casting it as proof that rapid green transitions don’t work.
While I do agree that we should research fusion, it doesn’t really address all the issues of fission. It still has some nuclear waste generation; not from spent fuel but from the reactor walls being bombarded with neutrons, causing some of that material to become radioactive, and it will likely require even more complex facilities and so have the “you need to spend a massive amount of time and money to get a reactor online” economic issues fission has, but possibly even worse. The physics technically give you more energy per amount of fuel and the fuel is more abundant, but that doesn’t necessarily mean that the resulting electricity will be cheaper, especially when both systems use so little fuel anyway.
It does avoid the possibility of a runaway reaction/meltdown I guess, but modern reactors are pretty good about avoiding that anyway. For that matter, newer (relatively speaking) fission reactor designs exist that can process waste into more fuel (not forever obviously, the fuel can’t be infinite, but enough to greatly extend the fuel supply and deal with much of the waste issue at the same time). The fission waste issue is also a bit overblown; the actual volume is very low, so just digging a handful of very deep storage facilities to stick it in is a viable option for an extremely long time.
The biggest issue for fission, imho, is that we simply don’t build very much of it. The less of it we make, the smaller the pool of people and facilities that are equipped to run it, maintain it, build the components etc, and the more expensive running it or building more becomes.
