When something goes badly wrong with a nuclear power plant, the entire human population sees an uptick in cancer rates and a chunk of the planet gets declared uninhabitable for 10,000 years.
That's true of only fission reactors, but TFA is talking about fusion reactors. Aside from the radiation being much, much less, it has a much, much shorter half-life. Additionally, the chances of something going horribly wrong are much, much less since fusion reactors can't have a run-away chain reaction.
