I might be missing some information, but why not? The Chernobyl disaster happened on a world power with strong scientific and engineering capabilities. I don't see how a power plant that's 15 years over expiration date like Tihange couldn't be a couple of serious mistakes away from a similar catastrophic meltdown. This is not "Tihange will definitely melt down". This is "there's a small chance Tihange might melt down and render a significant part of Belgium and Germany uninhabitable like parts of Ukraine and Belarus are uninhabitable now" which to me is unacceptable.
