Used nuclear material is not capable of killing everyone in an accident, nowhere close. More people have died drilling for and refining oil than have died in nuclear accidents, and that’s before we consider the existential risk that global warming poses.

And how many people have died in the strip mining of uranium?

[ashtonkem]

Probably not as many as you think.

Studies from a New Mexico mine ending in the 1970s estimated an extra 62.4 deaths per 100,000 miners. That’s a lot, but it doesn’t even hold a candle to coal mining in the same era. In 1970 the coal mining fatality rate in the US was 960 per 100,000 (1,388 fatalities for 144,480 miners).

Secondly, most uranium is leeched from the ground, not strip mined. This is far safer for the worker, although it does pose other safety considerations for the community.

Third, we can change these things. Coal mining has gone from ~900 per 100,000 workers to ~24 per 100,000 workers. Workplace health and safety standards are a choice we can make as a society. If we can make coal mining safer, there’s no reason we can’t make uranium mining safer.

Is that true per joule?

[ashtonkem]

Yes.

The estimate is that nuclear kills 0.04 people per TWh produced. This includes mining, refining, and the construction and operation of nuclear power plants. Natural gas kills about 4 people per TWh produced, making it far more lethal than nuclear all considered.

Fascinating in a grim way, rooftop solar is actually more lethal than nuclear, at 0.44 per TWh. Quite literally more people have died falling off roofs installing solar panels than died at Chernobyl. With rooftop being such a minuscule percentage of global production, expect that number to change.

By and far the most lethal is coal. The world average is 161 per TWh. But that average is hiding a lot of nastiness, because the true range is between 15 (US) and 278 (China). Quite literally millions of people die each year due to pollution, most of them because of coal.

This is a classic case of how people don’t calculate risk correctly. Nuclear accidents are scary, rare things and so people focus in on them. But in trying to get rid of nuclear we’ve ended up shifting primarily to coal and natural gas, energy sources that kill multiple orders of magnitude more people than nuclear does. But because these people die one at a time in hospitals, we end up missing the scale of the tragedy as a society.

All numbers valid from 2008.
