That chart needs a companion chart showing “amount of effort needed to prevent deaths”. Since that is missing lots of people think nuclear is safe when it’s actually by far the most dangerous.
Such charts exist - they're the "costs per unit" charts; perhaps broken down into (say) capital upfront plant costs, ongoing running costs per unit generated, and decommissioning costs.
It's the decommissioning costs for both nuclear and fossil fuel plants that are most often missing or overlooked.
True enough but there's an order of magnitude difference in those costs. For nuclear the costs extend beyond out ability to predict the future, and they simply can't be ignored whatever they amount to.
A fossil plant can simply be abandoned, and the damage will be minimal compared to abandoning a nuclear plant.
Without this information the chart is repeatedly used as an argument that nuclear power is safe, which is of course the direct opposite of the truth. It is the option that requires the most money and effort to keep safe and nothing is even a close second.
Nuclear power plant after removal of nuclear fuel and decontamination is inert as abandoned fossil plant. Such cleaning at end of life has to be done also for many kinds of chemical plants, chemical storage tanks, otherwise you get a catastrophe like in Bhopal, India.
If you are looking for long term storage of spend nuclear fuel, it's mostly a political issue, not technical issue. In U.S. there is WIPP, in New Mexico, a deep geological repository licensed to store transuranic radioactive waste for 10,000 years. But this is only licensed to store military nuclear waste, not civilian nuclear waste.
There is also hazardeus chemical waste which is stored in underground. The Herfa-Neurode underground landfill ( UTD Herfa-Neurode ) is the world's largest underground landfill for hazardous waste, includes 690,000 tons of waste containing dioxins and furans , 220,000 tons of waste containing mercury , 127,000 tons of waste containing cyanide , and 83,000 tons of toxic waste containing arsenic.
