Nuclear Energy: the Case Against (theguardian.com) 362
"We do not need to plunge headlong into a nuclear future," argues Serhii Plokhy, author of the book Atoms and Ashes: From Bikini Atoll to Fukushima.
He notes Belgium's adding a 10-year extension to the life of two of its nuclear reactors, France's program to build 14 new reactors, and Boris Johnson's pledge to create supply 25% of the UKs power needs with nuclear energy by 2050. On the surface, the switch to nuclear makes sense. It would not only enable European countries to meet their ambitious net zero targets, since it produces no CO2. It would also make them less vulnerable to Russian threats, and allow them to stop financing the Russian war machine....
What the Russian takeover of [Ukraine] nuclear facilities exposed is a hazard inherent in all nuclear power. In order for this method of producing electricity to be safe, everything else in society has to be functioning perfectly. Warfare, economic collapse, climate change itself — all of these increasingly real risks make nuclear sites potentially perilous places. Even without them, the dangers of atomic fission remain, and we must ask ourselves: are they really worth the cost...?
Technological developments, growing international cooperation and rising safety standards did indeed do a great deal to ensure that no major nuclear accident occurred for 25 years after Chernobyl. But the Fukushima explosions demonstrated that such improvements have not eradicated the dangers surrounding nuclear power plants.... Can anything be done to make reactors safer? A new generation of smaller modular reactors, designed from scratch to produce energy, not to facilitate warfare, has been proposed by Bill Gates, and embraced, among others, by Macron. The reactors promised by Gates's TerraPower company are still at the computer-simulation stage and years away from construction. But his claim that in such reactors "accidents would literally be prevented by the laws of physics" must be taken with a pinch of salt, as there are no laws of war protecting either old or new reactors from attack.
There is also serious concern that the rapid expansion in the number of plants, advocated as a way of dealing with climate change, will increase the probability of accidents. While new technology will help to avoid some of the old pitfalls, it will also bring new risks associated with untried reactors and systems. Responsibility for dealing with such risks is currently being passed on to future generations.
This is the second great risk from nuclear power: even if a reactor runs for its lifetime without incident, you still have a lot of dangerous material left at the end of it. Fuel from nuclear power plants will present a threat to human life and the environment for generations to come, with the half-life of some radioactive particles measured in tens of thousands of years.... Nuclear power plants generally have no alternative to storing their high-level radioactive waste on site....If what we bury today in the New Mexico desert — the waste created by our nuclear ambitions — is so repulsive to us, why do we pass it on to others to deal with?
The author's counter-proposal: expanding the use of renewable energy: New research should be encouraged, grid infrastructure should be built up, and storage capacity increased. Billions that would otherwise go to new nuclear infrastructure, with all the attendant costs of cleanup that continue for decades and beyond, should be pumped instead into clean energy.
In the meantime, we obviously have an existing nuclear industry, and the solution is not to run away in panic, but to take good care of the facilities that already dot our countryside. We must not abandon the industry to its current state of economic hardship, as that would only mean inviting the next accident sooner rather than later.

You're just demonstrating your Gen 3 technological ignorance. Nuclear power plants like being near bodies of water, which is why they like coastlines. That is because Gen 3 nuke plants use pressurized water to do the transfer of energy and keep the reactor cooled.
But you don't need to use H2O in a 4th generation nuke plant. Molten salt reactors don't use H2O for cooling or heat transfer. Molten salt has a higher temperature threshold, so they don't need to be pressurized either. Finally, the reactor can be designed to drain off molten radioactive slurry into safety storage, no control rods to screw up. This makes nuclear plants way, way safer than Gen 3 nuke plants.
A nuke accident like Chernobyl will never happen, except in former Soviet nuke plants that may still be in operation. The Fukushima fiasco was totally avoidable. They should not have left spent fuel rods at the location, which required "active" cooling. None of those problems experienced could ever happen to a Gen 4 nuke plant, running on molten salts.

Fukushima was built 10 years before Chernobyl was BUILT, in 1967. They didn't finish building the first reactor at Chernobyl until 1977, and the disaster didn't strike until nine years after that, in 1986. Using Fukushima to call the safety of modern reactors into question is either stupidity or intentional deception. Regulations can only do so much in the face of antiquated technology.
The biggest problem in my eyes with traditional nuclear is that the reactors are so incredibly expensive to build, that there's *huge* incentive to keep antiquated reactors operating as long as possible. Long after everyone knows they really should be retired.
That, and practically every reactor is a custom job, or at best a very limited edition run. Which means every one has its own unique, undiscovered, flaws.
I'm much more hopeful about modern small modular reactors coming off an assembly line and installed in a site-specific power plant. Any specific failure is limited, and any problems or weaknesses translate directly to lessons for every other reactor of the same model in the world. And mass production and modularity promises to drive cost per GWh down low enough to dramatically reduce the incentive to milk a few more decades out of a reactor that you know should be retired. You don't have to decommission a whole power plant - just shut that crusty old reactor module down and swap it out with a newer, safer module. The rest of the plant is mostly unaffected.

>And why was an old nuke plant being run? Money.
Not just money - huge amounts of money. Traditional nuclear plants are ridiculously expensive to build, and would quite likely never actually break even without being indemnified against responsibility for any possible catastrophe.
Which is exactly why I like modern reactor designs and especially SMRs - they address most of the potential economic failure modes - something large reactors decidedly do not.
Most modern reactor designs are extremely unlikely to fail catastrophically - for many of them (like molten salt) an explosion is basically impossible - the fuel itself is designed so that the reaction chokes itself out unless the rest of the plant is actively pulling away heat fast enough to keep it going. Had the same tsunami struck a badly managed modern reactor with all of Fukushima's other problems, it would just shut down.
Individual SMRs are also small, so even if you manage to make a reactor explode somehow, it's only going to affect a relatively small area, quite likely never escaping its protective vault (aka reinforced hole in the ground).
SMRs are produced on a factory assembly line rather than in-place - so any corner cutting in production that causes a problem is going to lead to a massively expensive recall of thousands of identical reactors, far exceeding the damage done.
Far less money is associated with each individual reactor - especially since it's essentially a "battery" plugged into a power plant, not the whole power plant. So if a particular reactor shows damage you don't shut down the power plant and stop making money (and then incur enormous expense decommissioning it) - you just shut down one reactor for replacement. Potentially not even reducing production as many power plant designs call for (relatively simple and inexpensive) vaults for at least an extra reactor or two so that you can get the replacement up and running before you shut down the one that's at risk.
There's still a vulnerability to malicious activity - I don't think there's any realistic way to completely protect against, e.g. being intentionally targeted by military action or sufficiently competent terrorists. But there are now options that are almost completely immune to greed and incompetence, which are the far larger threats.

Good point.
Where geothermal works it's *awesome*. Unfortunately it's really only well suited along major fault lines that allow lots of heat to accumulate near the surface. In most places it would be prohibitively expensive to drill deep enough (many kilometers) to get enough heat without also fracking (with all the geostability issues that introduces). And in many locations the local rock structure is sufficiently water-soluble to present serious fouling concerns, dramatically increasing the operating costs. And the world being what it is, cost gets the final say in the matter - though we could help things along with massive subsidies.
An interesting overview on the topic: https://www.youtube.com/watch?... [youtube.com]
Oh, and nuclear in the form of SMRs could be rolled out extremely rapidly. There's already pilot factories being built for the reactors, and power plants are very similar to coal or gas plants (aside from the reactor vaults) - to the point that there are several proposals on how to quickly retrofit existing plants to use them. It's primarily regulatory hurdles aimed at massive reactors, along with NIMBY opposition, that are likely to slow adoption - thing which governments can sweep out of the way at will, and often have for other things.
The short-lived nuclear waste is also a potentially valuable resource, as it's exactly the sorts of materials needed for RTGs and other "nuclear batteries". I would be opposed to widespread use of such things on Earth because of the contamination risk they pose (though Russia at least is fond of powering remote lighthouses that way) - but with SpaceX's Starship poised to enable the industrialization of space, there could be a huge demand for such things in an environment where contamination would present a negligible change in ambient radiation levels.
Heck, with a little caution you could turn the waste storage facilities themselves into good sized power plants in their own right by harvesting the decay heat.

The US has made a massive regulatory burden on building new nukes, especially the ALARA rule https://www.cdc.gov/nceh/radiation/alara.html [cdc.gov], which essentially means that any new improvement in nuclear power which saves money has to be immediately plowed back into reducing radiation even further, making it very difficult for nuclear power to commercially compete.
The particulars of his argument are also not compelling. And frankly, any book that is titled "Atoms and Ashes: From Bikini Atoll to Fukushima" is pretty clearly from someone with a pretty big axe to grind. (Hint: Bikini Atoll was a bomb test which has nothing to do with the safety of nuclear power.) The concern about building more plants for example doesn't make sense; if countries simply adopted the well known French, German, British and South Korean designs, there wouldn't be any issue. And things get safer when you have more copies of something because you learn from errors and mistakes made. A single airplane of a single design is not very safe. A hundred airplanes of that design is by nature safer. Same applies here. His other arguments are also uncompelling. For example, yes waste is a problem, but it isn't a massive problem, and we've thought a lot about where to put it. Even in the worst case scenarios, the amount of room needed to store the highest level wastes is not much larger than the areas needed to be cordoned off from any large industrial process.
He's also engaging in what is essentially a false dichotomy that things have to be either "clean" energy like wind or solar, or nukes. But we can and should build both. An all solar/wind grid is going to have a lot of trouble providing power when there's not much sun or wind, and that's true even with advanced battery systems, pumped hydroelectric storage, and large-scale HVDC transmission lines. But a system with some nuclear for baseline along with a lot of solar and wind works better.

This is a valid point. If you build your nuke plants near where you have coal plants you are getting rid of you don't have to build as much but still need to build some more.

Grid storage assumes there are significant surpluses of energy at times to store, presumably from renewables. Britain and nearly every other large nation runs deficits in renewables, mostly covered by burning gas and adding to global CO2 levels. There is usually no surplus to store hence there is no point to building more storage (Britain already has two large pumped-storage stations, one more is being considered but its utility is in doubt since we're burning lots of gas instead).
Nuclear power plants produce electricity without emitting large amounts of CO2. Storage does not generate any electricity in itself, indeed it wastes some electricity in the round-trip from input to output.

When you think X is the solution to everything, you can only see problems with Y. For example nuclear advocates like to say how do you use renewables when the sun isn't shining and the wind isn't blowing? Well it turns out that nuclear has the mirror problem: you can't save money on nuclear plant operation by turning down the output. That means you have to sell you power when demand and prices are low. The real problems with nuclear power plants haven't been safety or proliferation, although those are important. It's been you can't make money with the things. That's why Texas is building wind plants like crazy but not nuclear plants; it's easy to make money with them.
