Regulators noticed that the were spewing tens of billions of tons of highly destructive waste into the atmosphere with no regard to surrounding populations, numbering in the billions.
The regulators couldn't give a rat's ass. Oh wait, there are no regulators for the dangerous fossil fuel plants that kill indiscriminately with bizarre inattention to risk by a stupid and distracted public.
In fact, the nuclear industry is totally open about this problem at Chalk River - which will, unremarked by dumb fundie radiation paranoids - likely cause deaths because radioisotopes will not be available to sick people,
who depend on nuclear technology for their lives. On the other hand, there is no evidence whatsoever that the failure to make "safety upgrades" would have lead to a single loss of life. So, in effect, as usual, the anti-nuke fundie cult is trading
certain death for
theoretical risk.
Here are some remarks about the matter from a nuclear industry website:
http://www.world-nuclear-news.org/RS/Investigations_accusations_over_isotope_crisis_150208.htmlNuclear energy doesn't need to be risk free to be better than every other form of energy on earth. It merely needs to be better than everything else, which it is. Simply because people play
selective attention to energy risks -

http://ventdubocage.net/accident6.htm">the injurees, and evacuations connected with this incident (Report in French, video narration in Danish) or

In the last case, what is interesting that for each 100 operating years of the energy system, 10 storm failure events are on average required. That's a failure rate of about 10%.
This of course, is not to say that the form of energy - which, although it is a trivial form of energy still produces a significant number of fatalities, injuries, property destruction and environmental pollution, is as bad as the dangerous fossil fuels about which the anti-nuke fundie cult couldn't care less. This form of energy does not need to be risk
free to be superior to dangerous fossil fuels. In fact, there are no forms of industrial energy that are as dangerous as dangerous fossil fuels. Still the point is well made that anti-nuke fundamentalists want to ignore the risks of all forms of energy
except nuclear energy. This is morally, intellectually, and scientifically dishonest and arbitrary. Because of the nature of the crisis before humanity, the exposure of such arbitrary bad thinking should be immediately confronted.
