I view nuclear as a prudent diversification of energy sources: What happens if some supervolcano erupts, and because of the ashes significantly less sunlight reaches the surface of the earth. Presumably, there will also be less wind then.

Are we playing What-if? What if hackers/terrorist attack the power plants? What if the operating companies values profit over security? What if an earthquake or Tsunami hits nuclear power plant?

Am I stupid or naive to ask:

    > What if hackers/terrorist attack the power plants?
Are most power plants in 2025 air-gapped? I assume yes.

> $20B for 300MW Estimated 20B CAD for 4 x 300MW power stations.

Is that competitive compared to solar/wind + battery? I doubt it.

The press release claims it is. But other jurisdictions can build 1GW of solar + battery for $2B.

this sounds like one of those Google PR moments where they desperately try to paint themselves as the good guys. Remember when they announced contact lenses to help people with diabetes? Maybe this is related to the talk about splitting Google that's going around these days?

You don't think Google is interested in getting more energy for less money?

Nuclear (hopefully fusion at some point) is the only plausible way to meet energy needs in the future (that we currently know of). Fear of nuclear waste isn't irrational, but highly overblown because catastrophic events are more emotionally compelling than the slow degradation of either living standards and/or environment caused by competing technology.

30 years ago, I would have said the same thing. But right now solar is seeing technological advances at an exponential rate, such that by the time we build a nuclear power plant, get it approved, and get it running, solar will be both cheaper and safer while using less space.

Solar isn’t dispatchable and adding 24 hour storage doubles the cost. Adding seasonal storage increases the cost by 150x.

Every compute company knows that power shortage is a looming crisis. They don't have nuclear expertise in-house and are desperately looking for somewhere to put their money that seems to have experience and capability This is a good thing, but will be fruitless unless the US NRC modernizes in parallel with the industry to actually approve a new reactor in less than geologic time.

Ignoring AI (don't @ me) what are we doing with all that compute? Google (the search engine) hasn't meaningfully changed. Shopping is still largely the same as when Amazon first started out. Websites are pretty much the same. I don't understand what we're doing with all those operations. I guess VOD is new, but does that really demand that amount of compute?

More people and more companies engaging in digital services which are backed by Google cloud or another cloud?

Oh, it's the NuScale guy again. NuScale got far enough to get approval to build a test reactor at the Idaho Reactor Testing Station, which is in Outer Nowhere for good reasons. But they never got enough funding to build it. The trouble with most of these small modular reactor schemes is that their big pitch is mostly "we don't need a big, strong, containment vessel because ... reasons." There's no inherent problem in…

- "That's possible with distilled water as the working fluid"

Distilled water is pretty corrosive at high temperatures, isn't it? I'm no engineer but I've read that the water-chemistry management of nuclear reactors is a highly finicky topic.

Here's a crazy fact I can't get out of my head: the PWR types of reactors rely on lithium hydroxide in their nuclear water pipes, as a critical corrosion inhibitor. But the US can't make this (meaning, the isotopically enriched lithium of the correct flavor for nuclear reactors); it imports 100% of this key ingredient from foreign countries— currently, exclusively, China and Russia. Our top geopolitical adversaries could kneecap most of our nuclear power fleet, if they wanted, because of the difficult engineering minutae of "water is corrosive".

True story. https://www.gao.gov/products/gao-13-716

> Nuclear (hopefully fusion at some point) is the only plausible way to meet energy needs in the future (that we currently know of). This is simply false. At this point, its falsity has been sufficiently well demonstrated and communicated that you should have known it was false. If you are not deliberately lying, it's only because you steered yourself away from learning the truth.

Solar and wind aren’t reliable energy sources. They’re not dispatchable 24x7 and fluctuate along various timescales. Storing renewable energy for 24 hours doubles the cost. Storing it seasonally increases the cost 150x. Show me any place, anywhere, which is using renewable for baseline energy production 24x7.

At this point, that’s sufficiently well known that you should have known it. If you’re not deliberately lying, it’s only because you steered yourself away from learning the truth.

> Fukushima - meltdown, too-small containment vessel, large disaster. Probably overselling the "large" there... at least on the scale of global power production.

You wouldn’t call Fukushima a large disaster?

The financial cost is at $180 billion US. That seems large.

Life spans of reactors can cause instability. Nuclear requires unstable mines for unstable materials which are unstably finite. Controlled by unstable governments and where by a nuclear explosion causes a very unstable aftermath. I see nothing stable about nuclear.

Unless, you mean renewable being "unstable" in the sense of no wind, no sun equates to no power. Then yes, but only until the fuel is spent.

However, renewables are stable when resources are available, stable in providing consistent clean fuel and stable in cost on upkeep than say one of a nuclear reactor.

Which is why you combine all three.

> Show me any place, anywhere, which is using renewable for baseline energy production 24x7.

El Hierro, the smallest of the Canary Islands, holds a unique distinction as the only island to operate solely on wind and waterpower for 28 consecutive days.

The facility ingeniously combines wind generation with pumped storage hydroelectric generation. Now that's cool.

I think you probably just disagree with OP about the levels of our energy needs in the future.

If we just sustain human life and pleasure then yeah renewables are probably fine. If we want to pursue highly energy intensive applications and then further if we want to pursue those applications with mobility then we need nuclear.
