Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

This is not debate club. Unless it’s amusing debate.

Honestly thank god they're vaporware. Somehow I don't think we should have startups building actual nuclear reactors.

[–] skillissuer@discuss.tchncs.de 5 points 3 days ago

hol up google wants 500MW? that's 1. one regular sized reactor that could be delivered in the same timeframe, and 2. google uses already almost 3GW on average (2023), this is compared to about 2.5GW for ms of which something in the ballpark of 700MW just for ai. they're gonna need much more, like five regular sized reactors if they want to use entire baseload (that's how NPPs work best. the french made load-following NPPs but i guess it'd be harder to make them small) or swing wildly with power consumption to conform to renewables

500 megawatts? Pshhj that's not even though to power the flux capacitor.

[–] zalgotext@sh.itjust.works 11 points 4 days ago (2 children)

I can easily get 500 megawatts with a few power towers burning rocket fuel, plus I don't have to worry about the logistics of recycling uranium and plutonium waste.

I'm unrelated news, the Satisfactory 1.0 update is pretty great. What are we talking about again? Oh sorry gotta go build another heavy modular frames factory

this game destroyed my life for weeks. I'm doing shapez 2 now and I'll probably finish up my miserable tour of factory games with factorio afterward

EDIT: also rocket fuel seems extremely overpowered to me, I don't think powering tier 9 should be as trivial as making some RF and slamming down fuel plants for ten minutes

[–] vrighter@discuss.tchncs.de 4 points 4 days ago (1 children)

I'm more of a factorio guy myself. I'm going to become a hermit next monday

Great game, just sucks the main dev is a bit of a chud.

Edit: A Source

We buy tech of the future that might or might not work/get government approval/make actual sense to build so we can't be blamed for ruining the climate with AI using up all the energy. That's the more earth bound version of: I don't care about climate change because we will live on Mars soon^(tm)^.

BRING IT ON NITPICKY NUKE NERDS

Well acthtually we prefer to be called fission/fusion nerds

"greenwashing is cheaper than action" indeed. (edit2) On that note, storytime about the clownshow that is Dutch politics. So our radical right wing government is pro nuclear power, of course, and they want to build more powerplants. So what are they planning on doing? They are going to start a study on which locations are best. Which is maddening, as these studies have already been done before (so it prob is just an attempt to hopefully have the study finish when it isn't them in power anymore so they are not at risk of starting an too expensive megaproject). But it gets worse, the absolute clowns of our farmers party just went 'fuck the studies' and they just pointed at a province where there are a lot of farmers and went 'we will put a powerplant there'. And this is how they discovered nuclear powerplants need running water and they picked one of the areas without a major river. ('im ignoring the clownshow re 'the immigration crisis' (not a crisis) as this post is already too long, and there is a big risk of honk overdose if I go into that).

Our local Swedish right-wingers in gov have a chubby for nukes too[1], because their main motivation besides hating on brown people is pissing off Greens. But in the Swedish way they handed this off to a researcher ("utredning") who found out that to get the industry on board you need a) rock-solid political promises (so need to get the Social Democrats at least on board) and b) have a price guarantee for power for at least a decade, along with massive government loan guarantees.

It's gonna be hard to get voters interested in 10 new reactor sites (NIMBY gets supercharged when it comes to nukes) if it slightly pushes up lending rates and power bills.


[1] the right-wing part of the opposition social democrats like them too to be fair

I'm looking forward to seeing the tech attitude of "move fast and break things" being brought to nuclear reactors.

If these nuclear plants manage to come to fruition, it'll be the sole miniscule silver lining of the bubble. Considering its AI, though, I expect they'll probably suffer some kind of horrific Chernobyl-grade accident which kills nuclear power for good, because we can't have nice things when there's AI involved.

[–] dgerard@awful.systems 17 points 5 days ago (1 children)

even if you're ardently pro-nuclear, SMRs are just a failure purely on the economics and always have been. And that's before wind/solar/battery made them just obsolete. So SMRs are the perfect tech when you don't want to do anything useful.

See, I feel like AI might have the actual solution to this problem. We can overcome the economic issues with setting up SMR infrastructure the same way AI has powered through all their economic problems: setting VC money in fire and trust that the smokescreen will hold out for another funding round.

Once the reactors exist, I'm assuming that their operation can be relatively cheap for whoever ends up owning the actual plants once the AI bubble pops and the datacenters around them are shut down or repurposed.

I am 100% in support of deploying nukes to Google and Amazon

[–] drd@lemmynsfw.com 10 points 5 days ago (1 children)

You need to deploy them around the same time else contingency plans have it that everything just boots back up in another region, at least Google. us-east-1 otoh...

[–] dgerard@awful.systems 8 points 4 days ago

us-east-1 is Amazon's Self-Nuking Technology(tm)

BRB making a video for a cold fusion based kickstarter. I smell money

[–] Moonrise2473@feddit.it 17 points 5 days ago (1 children)

Remember to say it's optimized for net zero datacenter operations

Thanks for posting this good collection of links. HN has as hard-on for SMRs and as a first-order approximation that means they're wrong, but it's good to have something more than vibes backing it up.

[–] dgerard@awful.systems 14 points 5 days ago

I got a lot of them from very pro-nuclear guys too, but ones who can count

[–] skillissuer@discuss.tchncs.de 21 points 5 days ago (2 children)

how come all these botfans talking points are just repackaged cryptobros talking points

it keeps happening

[–] dgerard@awful.systems 17 points 5 days ago (1 children)

you'd almost think they were literally the same fucking guys

[–] skillissuer@discuss.tchncs.de 14 points 5 days ago

coincidence?? yeah probably

I don't claim to be an expert on nuclear power, so take what I say with a grain of salt, but from what I've seen, smaller reactors don't seem to make much sense. The trend seems to be towards bigger reactors with bigger power output. Some of it thanks to the bureaucracy of getting permits per reactor, but also the physics, engineering, real estate and economics involved. Conventional (i.e. existent) reactors are typically a fairly small part of a nuclear power plant's footprint, so no matter how much you miniaturize them you will have the overhead of security, operations, cooling and electrical infrastucture.

If someone can fill me in on the benefits of smaller, more modular nuclear reactors and how they might outweight those of large installations, I'm interested.

[–] skillissuer@discuss.tchncs.de 16 points 5 days ago

square-cube law is in full force there

one argument in favour of SMRs i've seen is that while less efficient than regular sized reactors, these are cheaper per unit (but not for MW) so some of them can be built earlier than bigger reactors. which doesn't matter because these things don't exist

[–] dgerard@awful.systems 14 points 5 days ago

The hypothetical benefit is that prefabricated parts are a lot less dependent on the site. This will make the reactor cheaper to build.

There's also a perception sleight of hand - "modular" doesn't mean the reactor is a module you ship in on a big truck, put some uranium in and away you go. You're building a power station in a fixed location.

Also you still need a shitload of water.

[–] blakestacey@awful.systems 17 points 5 days ago* (last edited 5 days ago) (2 children)

Google has signed a deal with California startup Kairos Power for six or seven small modular reactors. The first is due in 2030

So, well after the bubble is going to pop.

I swear they looked at Bill Gates failing to launch SMRs and thought: "he's a smart guy"
