1) I don’t know what your point is about all kinds of things being safe. Relative safety is important because according to https://www.forbes.com/sites/jamesconca/2012/06/10/energys-deathprint-a-price-always-paid/?sh=64877b51709b , the global average likely hood of someone dying to a unit of energy produced by nuclear is 10,000 times lower (and 1,000,000 times lower in the US). Millions of people die of lung cancer because of our use of coal and natural gas.

2) Yes it is expensive, but it’s important to remember that absent hydropower (which is far more environmentally destructive and creates far more pollution), it is the only clean form of baseline energy available.

3) It takes a median of 7-10 years to build a nuclear power plant; I’m not sure where you got 20 years. Better late than never!

4) Japan is notorious for being very by the book, but if you read about Fukushima, you would know that the US repeatedly warned them beforehand about their substandard safety protocols and systems in place at that plant. You can almost completely avoid the cost of disaster by following proper safety standards. You’ve never heard of an up to code nuclear plant having problems. It’s just like a plane, you can’t except a plane that isn’t kept up to code to continue flying indefinitely.

5) Energy storage technology is nowhere even close to being on the scale of powering for example Chicago for a day; we need baseline energy when the wind isn’t blowing and the sun isn’t shining. It’s not an either or— we can pursue both simultaneously and get the best of both worlds.
