So yes, nuclear should be regulated, and even overregulated to keep it safe.
Here's what overregulation of nuclear power has done for us over the past several decades: "We can't risk releasing radioactive pollution in an accident, so we'll build coal plants that spew it into the air during normal operation instead."
Many countries shut down all their coal plants over a decade ago. Why didn't yours?
Sounds like the other systems are under regulated.
