That's not true actually. A fusion plant can leak highly radioactive tritium, poisoning anyone in the plant or relatively near. A magnetic containment plant can lose plasma containment and get a pretty giant explosion, definitely destroying the extremely expensive machinery, and likely also killing many inside the plant. This explosion would also throw parts of the radioactive reactor all around.

It's definitely nowhere near Chernobyl risks, but "if anything goes wrong it just stops" is not as guaranteed as is often made out.
