| So $235 million for 162MW, or $2.35B for 1.6GW A 1.6GWe nuclear reactor is around $8B. |

| These are… completely unrelated ratings? The heat pump generates 162MWt, at the cost of around 50MWe. The nuclear reactor produces 1.6GWe alongside 4.5GWt. Furthermore the listed costs are also unrelated: the 235 millions are for the bare units (and an estimate for something a few years out), while the 8bn are turnkey (of what exactly I’m not sure: the beleaguered Olkiluoto 3 and flamanville 3 cost 11~12bn, while Taishan is estimated at under 8 for two reactors). |

| ▲ | willvarfar 16 hours ago | parent [-] | | A heatpump needs power to operate, but will generate at least 3x more heat than the electricity to power it. The article describes how there will be a water battery. So it can be thought of as a part of a bigger countrywide or europe-wide plan and grid? | | |
| ▲ | pjc50 15 hours ago | parent [-] | | Sure, but if you build a nuclear reactor suitably close to your city (!) it produces hot water directly in addition to electricity. It's just a much bigger pain to ship hot water over long distances than electricity. | | |
| ▲ | renhanxue 8 hours ago | parent | next [-] | | Sweden's first commercial nuclear plant[0] was built right next to a newly constructed suburb precisely so that it could be used for district heating too. And also for producing small quantities of weapons grade plutonium, for... research purposes. Waste not, want not! (It didn't last very long and was shut down in the mid 1970's, for somewhat obvious reasons.) [0]: https://en.wikipedia.org/wiki/%C3%85gesta_Nuclear_Plant | |
