"It's ridiculous to say nuclear is the safest form of energy when it costs so much money" is a ridiculous argument.
The cost of nuclear may be a fair argument against it, and should definitely be considered when determing our energy policy. That doesn't mean it somehow kills more people.
Every form of energy has an inherent danger that humans can use money, will, and sacrifice to overcome.
If we’ve spent more money evacuating populations from irradiated areas than on training wind turbine technicians to use harnesses properly, does that mean nuclear energy is safer than wind power?
Yes? As even after that training, fewer people have died due to nuclear energy. Cost and safety are two separate points, both need to be considered but you can't just say something is unsafe because it's costly.
Imagine someone says "you have to either pay $10 to play Russian roulette with a five chamber gun or $100 to play with a six chamber gun." Which is safer?
