You do realize it actually is not getting worse? Fukushima barely killed any people, while Chernobyl has ~100 casualties. The radiation of areas around Chernobyl is bigger and more lasting than those of Fukushima.

Not to mention these are 50yo plants, and new ones are just better (whether or not you believe the tests/physics behind that).

It is disingenuous to claim nuclear plant safety is getting worse.
