Their hoped-for completion date is "2031". Anyone want to hazard a guess about what their actual completion date for this plant will be?

Presumably it’ll end up like the NuScale one, raise a few billion for design and prototyping and then every 6 months or so increase the target wholesale price by 50% until it makes no sense at all economically to begin primary construction. They’ll reverse IPO along the way and manipulate the stock enough to get insiders paid out while the carcass of a company trundles along.

  • No. They have Bill Gates as a founder. Bill Gates understands that nuclear is a long game.

    I'm not sure what "reverse IPO" means, maybe you mean they'll be acquired by a SPAC, like NuScale was. I doubt it. Bill Gates founded Terrapower in 2008, he is not looking for a quick buck.

  • In theory, at least, they have finished their design, had it reviewed by the NRC, and had it approved, so there should be no significant design changes.

    But that also applies for the current generation of reactors and nobody can build them to schedule or budget in the USA or Europe.

    • > so there should be no significant design changes

      The NRC frequently changes requirements for reactors while they're under construction. The NRC does not waive the right to demand changes merely due to prior design approval. This is a novel (for the US) design, so there will be unanticipated changes as the project progresses.

      Russia has been operating two sodium cooled fast reactors for decades. The BN-600 and BN-800 are both operating today. The early history of the BN-600 was... interesting, suffering (at least) 14 sodium fires due to leaks. This "Natrium" design is similar; a sodium pool with two sodium loops. They are taking on the additional challenge of storing a massive quantity of molten salt. It's going to take a lot of effort by many steely eyed missile people to make this happen.

      Trump issued an EO in 2025 that's supposed to make the NRC more circumspect about requiring changes of approved designs. Then there is all the pull Gates has. Wyoming is no hotbed of anti-nuclear activism. So that's all to TerraPower's favor. But TerraPower will need to fully utilize all the tailwind it can find to make this work.

No, but I'm certain the polymarket gamblers do.

  • I did have the same thought, had a quick look (I'm not a polymarket user) and couldn't find a market relating to this project.

    Put it this way, if it's in commercial operation by 2031 I'll eat my hat.

China have 28 nukes under construction right now, and have built more in the last 30 years than the rest of the world combined.

Even with all that experience and expertise, their questionable environmental policies and questionable worker rights, it still takes them SEVEN years to build a single nuke.

The claim that anyone else can do it faster with zero recent experience isn’t only laughable, it’s downright fraud.

  • The Chinese CAP1400s took 5 years and that's a new design to them. The first NPP was built in 1951 (ish) and took 18 months from blackboard to grid interconnection. Some designs take longer, others are shorter. Some parts of Vogal were rebuilt 3x times due to the federal government changing the design requirements multiple times during construction. Another challenge is that NPPs are built rarely enough that its hard to be a supplier to the nuclear industry so many parts are custom built per project. That doesn't have to be the case. The idea there is a hard limit of 7 years, sorry...that just isn't so.

  • Wow, that's A lot. Even though there's diminishing returns with more workers, they'd probably build them faster if they weren't scaling out so much concurrently, right?

    Seems like we could match a 7 year clip at a much smaller scale. We'll be forced to at some point, but we need to overhaul the regulatory mess and fix the grid first. Hopefully that happens long before battalions of Chinese drones and droids take over the world.
