Science Squabbling

fusion has little to no radioactive waste. And non radioactive fuel.

It's a totally different environmental cost, Fukushima, Chernobyl, Three mile island, all would be largely trivial in a fusion plant

But this isn't the case is it? Everything inside a fusion reactor becomes radioactive and parts wear out, need to be replaced and disposed of. So you still end up with a lot of radioactive material that you have to do something with.

Just because the fuel isn't radioactive, doesn't mean there's no problem.
