Engineer Dale Bridenbaugh resigned from GE in 1976 because he knew that the Mark 1 nuclear power plants' safety was dubious and the company was unwilling to do or say anything about that. Three of these plants had a meltdown many years later in Fukushima.

The US Nuclear Regulatory Commission knows the danger, and makes sure nothing is done to prevent similar problems in the 23 plants in the US. If they have a meltdown, don't call it an accident!

Nuclear power plant waste poses two problems: how to safely cool it down for the first few decades, and how to store it after that. Neither one has a safe solution.
