Building nuclear reactors that are easy to replicate is a SpaceX style problem: "What we're trying to do here is build a reactor which is easy to replicate. It's a little different from mass manufacturing. Different from a Tesla style problem, more like a SpaceX style problem. You have a complicated vehicle that you need to get really good at building and deploying in a repeatable fashion. When I first started the company, we didn't have a size in mind for the first reactor. It was very explicit. We told the team we don't know how big the reactor is going to be. We don't know how powerful it's going to be. We didn't know those numbers until a year to 18 months into the company. We told ourselves we are going to discover the power level through the manufacturing process. Our instinct was as long as that number turns out to be somewhere above 15 megawatts, we should be pretty good for mass production. If you're under 15 megawatts, it's pretty hard to scale the right way. You just end up doing so many different pieces of operations that it becomes more complicated. But our feeling is above the 15 megawatt break point, you have something that can really scale. And we think this reactor ends up somewhere around 25 megawatts. 25 megawatts being the sort of scale factor where if you want a gigawatt, you just build 40 of them. The next challenge for us as we turn this on and turn the next one on is how do we get to the place where we're turning on one reactor every day and then multiple reactors every day. That's how we're going to climb into the gigawatts."
