I see this as qualified good news. A power plant had a total meltdown but the world didn't end.
"The situation is far worse then we thought, but is didn't cause an apocalypse. Good news!" Riiiiight.
Maybe we can start to talk about nuclear risk more pragmatically.
Sure. The risk of fusion-as-we-know-it, including the unsolved problems of radioactive waste and weapons proliferation, are so high that, pragmatically, any sane society should abandon it as a dead end and put resources into renewables (including perhaps orbital photovoltaic), efficiency, and research into fusion and accelerator-based "energy amplifier" systems -- i.e., systems with a Big Red Switch you can flip to turn them off. It's only a romanticism with the Big Science of Splitting The Atom, a desire to normalize military nuclear technology, and the incredible profits can be made when the costs are externalized, that keeps the idea alive.
