I think a town burning down would be fatal for most the inhabitants 3000 BC

It’s sad that the coal lobby has convinced so many people that the most reliable clean energy source we’ve ever discovered is somehow bad.

Its bad in the sense that is a crazy expensive way to generate electricity. Its not theoretical. Ask the customers of the most recent nuclear reactors to go online in the USA in Georgia. source

"The report shows average Georgia Power rates are up between $34 and $35 since before the plant's Unit 3 went online. " (there were bonds and fees on customer electric bills to pay for the nuclear plant construction before it was even delivering power.

...and...

"The month following Unit 4 achieving commercial operation, average retail rates were adjusted by approximately 5%. With the Nuclear Construction Cost Recovery (NCCR) tariff removed from bills, a typical resident customer using 1,000 kWh per month saw an estimated monthly increase of $8.95 per month. This follows the previous rate impact in 2023 following Unit 3 COD of $5.42 (3.2%)."

So another $5.42/month for the first reactor built on top of the $35/month, then another $8.95/month on top of all that for a rough total of $49.37/month more just to buy electricity that is generated from nuclear.

Maybe the power company is greedy? Nope, they're even eating more costs and not passing them on to customers:

"Georgia Power says they're losing about $2.6 billion in total projected costs to shield customers from the responsibility of paying it. Unit 4 added about $8.95 to the average customer's bill, John Kraft, a spokesman for the company said."

So that $49.37/month premium for electricity from nuclear power would be even higher if the power company passed on all the costs. Nuclear power for electricty is just too inefficient just on the cost basis, this is completely ignoring the problems with waste management.

The next biggest problem with nuclear power is where the fuel comes from:

"Russia also dominates nuclear fuel supply chains. Its state-owned Rosatom controls 36 percent of the global uranium enrichment market and supplies nuclear fuel to 78 reactors in 15 countries. In 2020, Russia owned 40 percent of the total uranium conversion infrastructure worldwide. Russia is also the third-largest supplier of the imported uranium that fuels U.S. power plants, accounting for 16 percent of total imported uranium. The Russian state could weaponize its dominance in the nuclear energy supply chain to advance its geostrategic interests. During the 2014 Russia-Ukraine crisis, Russian Deputy Prime Minister Dmitry Rogozin threatened to embargo nuclear fuel supplies to Ukraine." source

So relying on nuclear power for electricity means handing the keys of our power supply over to outside countries that are openly hostile to us.

Particularly since coal power stations emit FAR more radioactive material, routinely, than most nuclear "leaks".

Europe's regulations are strict and robust. However, the German Greens convinced lots of people that they aren't enough.
