I believe this is why the USA recently declared that it's no longer going to follow the "linear no-threshold model" and "as low as reasonable achievable" principle of radiation exposure. In other words they're declaring that a small amount of radiation is good for you. Building a reactor without shielding and with a single open-cycle water loop should reduce costs, right?

(Do you know what else reduces costs? Apparently, putting a foot of graphite at the bottom of your control rods and not paying close attention to a dangerously unstable reactor during an unusual experiment. These aren't official American policy yet.)

Also, the USA's recent ban on solar electricity equipment should help make other forms more competitive.

Linear no-threshold and ALARA are pretty objectively overly conservative, to the point of potentially doing more harm than good (Fukushima is mentioned down below. More people died as a result of the evacuation than would have resulted from the radiation) as well as making many things obscenely expensive. It's a little absurd that nuclear plants obsess over radiation doses smaller than a short-haul flight.

Linear no-threshold being false doesn't necessarily mean a little bit of radiation is good for you, though there is some shaky data to suggest that might be true, just that small amounts of radiation are not as proportionally bad as large amounts.

The harms of radiation are massively overhyped.

Nobody from the Fukushima accident died from radiation sickness or radiation syndrome, and so far there's been no evidence of long term elevated cancer rates either.

Meanwhile the nuclear industry has been drowning for 50+ years from egregious layers of overregulation.

It costed NuScale $500+ Million just to write the documents required for regulatory approval for a new reactor design.

Microsoft is spending $60 Million a year to build an LLM whose only purpose is to automate writing nuclear regulatory documents.

I don't support the Trump admin one iota, but I'm also saddened that democrats tend to be too safetyist to do an honest cost benefit evaluation of some of these insane regulations.

You say these two things as if the second statement supports the first, but it doesn't.

The dangers of radiation are very well known and don't change at all based on what happened at Fukushima. If you fire a gun and miss, the gun is still dangerous.

Here's an account of two gruesome deaths caused by poor regulation of nuclear materials in Japan. It happened 12 years before Fukushima.

Interesting but people die (or are severely injured) in all kinds of industrial accidents all the time. Unfortunately, with or without regulation it comes with the territory of a modern industrial society.

Very few other industrial accidents cause effects that have to be dealt with for decades over 1000 miles away, even across oceans.

Nuclear power really is in a league of its own when it comes to risk. I am not aware of anything that comes close. Dam accidents have killed many more people and devastated towns, but the day after that happens, the area can be reused and the risk is entirely gone. The risks of nuclear power remain for decades or even centuries.

Finding ways to deal with that risk is fine, arguing that it can be managed is fine, but pretending that the risk is exaggerated based on the accidents that have happened so far is a mistake.

The risk is things that could happen, not what has actually happened.

You probably mean the Chernobyl accident.

There are estimates that pollution from European coal power plants cause more deaths EACH year in Europe, than the total estimated deaths from Chernobyl accidents (most pessimistic estimate 4000-8000 deaths).

For example, just the Great Smog event that affected London, England, in December 1952 caused by modern estimate 10,000–12,000 deaths.

There has actually been 1 radiation death

How can writing documents possibly cost $500,000,000?
How could writing code possibly cost that much? And yet tech companies spend significantly more than that per year on it. You need a lot of highly paid, experienced people to do it (negotiating regulatory frameworks is pretty much its own profession).
