By reliability he refers to french nuclear plants stopped for months due to mantainance and repairs (mainly leaks that couldn't be scheduled). Painting nuclear as a 100% free of problem energy makes people sound as car salesmans. As of today, nobody want to finance or insure them. As soon as you say "ok, build them reactors if they are so perfect", nuclear advocates want the state to jump in and asume the costs, the…

> the consumers to pay an extra price The (botched) green energy transformation has given the country I live in top 3 highest electricity prices in the world and it's not even particularly green at all. Literally cannot get worse. And it seems to me that one half doesn't understand how incredibly bad high energy prices are both for people and industry, while the other half cheers at the prices because it causes deind…

As a French not expert in the matter but living near nuclear plants: - one of the plant regularly leaks radioactive material - rivers are getting too hot to cool down nuclear plants correctly - nuclear plants are very unreliable, we almost got out of power this winter and next winter will be equally tough (only an abnormally hot winter avoid cuts...) - the government wants to simplify control organism and laws around…

- one of the plant regularly leaks radioactive material In quantities not relevant to safety. We can detect extremely small amounts of radiation, down to 1.0001% higher than backrgound levels. - rivers are getting too hot to cool down nuclear plants correctly Not quite: the flow of rivers was low enough that they would exceed the 28C temperature limit (ostensibly to protect fish, but no adverse impact from higher tem…

They are referring to the leaking of tritium, which, while "technically" radioactive, regular water contains some tiny amount of tritium and deuterium naturally. They are barely radioactive, and you can actually buy them on Amazon - they are not regulated.

To say that the reactor is "leaking radioactive material" because of tritium is extremely dishonest.

Nuclear proponents when trying to sell nuclear love to shout about how successful France is. Someone from France is telling you that actually, it's really not that great...and now France's nuclear program is terrible and the result of 20-30 years of neglect and politics? Also, which part of "nuclear plants are sensitive to environmental changes" didn't you get? If there's no cooling water, or the water is too hot, th…

Someone on the internet is saying they are French, making claims that aren't backed up with sources or data.

> one of the plant regularly leaks radioactive material Probably just Tritiated water which is essentially harmless. Basically water with extra neutrons and it is very weakly radioactive. So weak that you can't detect it with a Geiger counter. Since it is water it does not accumulate in organisms. Tritium is also naturally created in the atmosphere by cosmic radiation.

That's exactly what it is - which is why the comment above is so profoundly dishonest.

You can buy tritium on Amazon - it's harmless.

> one of the plant regularly leaks radioactive material Please share numbers demonstration health hazards. For ex, bananas are radioactive. Should we outlaw bananas? > rivers are getting too hot to cool down nuclear plants correctly That's wrong. In 2022, the power output had to be reduced by 0.18% (not a typo) ( https://twitter.com/energybants/status/1645696906327388160 ). In addition, Nuclear plants can work even i…

You are making good points, however about the leaks, we obviously shouldn't wait for them to be dangerous to worry. It's hard to prove risks, it's also hard to prove the lack of risks if only for the living ecosystem around the plant. The leaks show issues in the alert system, it's not the first time it happened, and an engineer sued the plant for dangerous mismanagement. Doesn't mean we should drop nuclear energy ei…

And of course all risks should be weighed against the known risks and downsides of the alternatives.

Cue the atomic fanatics vs the renewable cult discussion. Has been discussed a thousand times on HN recently and it always seems both are just shouting how the other side can not see the obvious superiority of their fav energy source. why cant we have a bit of both? renewable seems very good long term and nuclear is also nice for transition. but I wouldnt want to live next to one of those crappy leaky french reactors…

No, we can't have a bit of both, because despite heroic efforts with tens of billions of dollars being dumped into nuclear since 2008, it hasn't produced. We tried four reactors back then, using a new regulatory process that was supposed to speed construction and reduce costs. Instead, costs and timelines ballooned 3x. Two of the four reactors were abandoned half-way through construction, resulting in rate payers hol…

I guess you think the Koreans and Chinese are just fundamentally different from everyone else then because they're pumping out reactors just fine, today.

The French, Americans, Russians, and Japanese have all had periods of time where they built them quickly and cost effectively too. But then various institutional rot sets in. We're going to have to keep building big things anyways so it's not like having that capability is wasted.

"I am not against nuclear power" - this is litterally the calling card of a tactical hit, forum-wise. It very obviously means the opposite of what it says. I generally look at how people perceive things like this as an IQ test. At the moment the HN visitors upvoting/downvoting things in this thread have failed my baseline IQ test. How I wish all presumably well-intentioned but badly informed and ill-educated people w…

:( no really I try to stay open-minded and found contradictory answers interesting, if only because they are well documented. My reply is also to the initial article, which is on the contrary way too optimistic. Nuclear energy is not black or white, I think sharing personal experience as someone living near a plant, in a country relying mostly on nuclear energy, is relevant.

You misrepresent tritium coming from a plant as a "radioactive leak". That's just dishonest nonsense.

For too much radtion, I recommend reading: https://www.wsj.com/articles/nuclear-regulatory-council-nrc-... ( https://archive.is/LITQT ). I'm not sure how France treats radiation levels, but in the US, the guidelines we have set are non-nonsensical.

> He is now co-founder of fission energy company ThorCon, which is developing liquid fuel fission power plants to generate electricity cheaper than coal, to solve the world climate/energy/poverty crises. I think nuclear will have an important part of dealing with climate change but he has a massive financial stake in this. I wouldn’t trust that more than I’d trust the Exxon guys who told us climate change was a liber…

The problem is that in government, you are rarely if ever punished for being top strict with your regulation. You are only ever chastised if you are too lenient (or the appearance of it). People like scapegoats and will use lax regulations anytime they can.

The problem is, a regulator never gets in trouble for being top strict. The incentives are totally wrong here and lead to bad regulations.

I trust this guy more than the bureaucrat covering their butt.

> Nuclear is the most expensive form of electrical generation while wind and solar are the cheapest. Except if you add the cost of 12 hours of batteries to solar it's massively more expensive. You can't just compare an intermittent source and a non-intermittent source, without factoring in the cost of storage.

>Except if you add the cost of 12 hours of batteries to solar it's massively more expensive. Nobody knows what nuclear costs, because nobody knows what it will cost to handle the waste 10 years from now, let alone 100 or 1000 years from now. The solution to this for most nuclear operators has been to pay a symbolic fee and let the taxpayers cover the rest "in blanco". When accidents happen, costs also arrive very sud…

We know exactly how to store nuclear waste: bury it underground in impermeable bedrock. We already have several of these [1]. Furthermore, the figures for the costs of nuclear power already include waste disposal [2].

Also, since most countries don't reprocess nuclear waste, it's actually good to hold onto it since it's a future source of fissile material.

1. Yes! 2. Just some more than we have now. 3. Yes! 4. Yes! Seriously though, I just want some reactor construction to spin up with non ancient reactor designs, to replace some fossil fuel plants. PBR[1] sounds good to me... but what do I know? There are experts who can decide this. 1: https://en.m.wikipedia.org/wiki/Pebble-bed_reactor

In the US we're replacing nuclear plants with renewables at a 6:1 ratio. The only people who think we need more nuclear power plants is the nuclear power industry and the politicians they're heavily lobbying to stay relevant.

CAISO penned a series of increasingly urgent press releases on how catastrophic closing diablo canyon would be for grid stability when it's closure was imminent.
