I ran the numbers for this about six months ago and it works out a lot better than all the other alternatives. The fact you're surrounded by coolant, can use intrinsically safe versions of high pressure reactors and have low latency between multiple markets with one datacenter is a big plus. That you're not competing with humans for electricity or water is another. That said you'd want to build a semi submersible pla…

So I take it you’re a marine engineer or similar?

Sure, lets heat up the oceans even more. The sensible way would be to use the waste heat for district heating, but let's heat the fish instead

It's a drop in a bucket. Global warming is due to ~5e18 Wh of excess heating. A nuke dumping 5e12 Wh of additional heat into water makes no difference at all.

YCombinator S26? Guys, guys, guys... so hear me out - remember last month when we were all giddy about datacenters in space? Well, apparently investors weren't too keen on that idea so we've come up with something much better: Nuclear datacenters at sea! Now this is truly a visionary proposition that will certainly become another unicorn and have no issues whatsoever.

Why not fusion powered data centers on the moon?

We just need to solve the issue of fine moon dust in those computer fan bearings /s

Up next: nuclear data center Zeppelins in the cloud!

Innovative new air cooling: instead of using lots of tiny fans to move air through the servers, we simply use 2 big fans to move the servers through the air!

And while we're at it, we'll completely disrupt the existing Zeppelin market that depends on expensive helium for some reason. We use daring, innovative hydrogen technology, enabling a massive cost reduction!

Current nuclear-powered ships are run by the world’s premier naval powers and protected by their own stealth or a huge array of armed escort ships. Have these guys factored in the cost of a task force of protective missile frigates, subs, and destroyers at each site?

Forget security (which worries me less), the legalities of this are notoriously tricky (especially if the ship might ever leave the waters of one nation), and the economics are even worse. I wouldn’t touch civil maritime nuclear with a barge pole, and if I did, the clear win is decarbonizing big cargo ships.

Agreed, the largest container ships put out some serious pollution, going nuclear (a decades old proven technology for shipping) would be a massive improvement

But the people championing nuclear data centers are not trying to solve climate change

No, but I did have my father check the maths and he built oil rigs for 30 years.

The current major roadblocks for any datacenter are, planning permissions, power connections, and cooling. The on a barge approach solves all of the above, unlike space which makes all of these problems worse.

Drops add up, just like using gas, oil, coal...
