Taylor: Three Mile Island Caused Zero Deaths, Injuries, or Public Radiation
“Not only did nobody die, nobody was injured, and there was no radiation dose to the public, but it was sort of a optics and PR situation that was mismanaged in many, many different ways, and the public became fearful and lost interest in nuclear.”
Taylor: Rebooting Nuclear Requires Shifting from Civil Infrastructure to Advanced Manufacturing
“If you're going to reboot nuclear and you're actually believe in, in the atomic energy century, which I absolutely do, it's probably not going to look like what it did in the sixties. It's not going to look like civil infrastructure. Because we're not that goo…”
Taylor: Manufactured SMRs Require Development Driven by Hardware Iteration

Taylor: Most Nuclear Startups Are Just Modeling and Simulation Companies
“So if you look at the nuclear industry outside of Valor, it's mostly a modeling and simulation industry. Like, when you think of a nuclear company, right, there's, like, nuclear companies out there that everyone knows the name of, and you kind of look under th…”
Valar Built and Turned On Reactor Under DOE Authority via EO 14301

Taylor: Nuclear energy causes fewer deaths per unit of power than solar
“Nuclear energy is the safest form of energy, empirically. If you look at the amount of power generated versus the amount of deaths it's even safer than solar, which is very strange, because how does someone die from solar? But actually, most solar is installed…”
Taylor: Minimizing accident consequence beats trying to engineer away low odds
“The alternative way that you can reduce risk is actually just reducing consequence, right? And we would argue that that's a much better way to reduce risk. Odds are stochastic, right? Even if you do an enormous amount of risk reduction on odds and you do all t…”
Taylor: Valar Atomics' safety basis proves zero radiation dose during total failure
“Our safety basis when we go to the regulator is everything in the plant has failed. Absolutely everything, right? ... In fact, it is safe. Right? So we have regulatory limits where we say, okay, in an accident scenario, you can't dose the public with radiation…”
Taylor: Nuclear energy requires mass-producing simple reactors like Toyota Camrys
“The problem of nuclear today is like the Toyota Camry problem, right? Like we don't want to make Lamborghinis. We want to make a very simple, very cheap, very safe reactor that we can make literally tens of thousands of. And actually that is going to make the …”

Valar Built a $5M Nuclear Reactor Component In-House For $400K
“And we were quoted about five million dollars and we were told it would take about two and a half years to build. And so we said, well, all right, maybe I'd be willing to pay five million dollars, but I'm certainly not going to wait two and a half years. And s…”
Taylor: Nuclear is a fake industry charging 100x margins
“Everywhere you look, it's a fake industry that has not been building anything for 40 years, and the little bit that they have been building, they're charging a 100 X margin on.”
Isaiah Taylor: Nuclear fission reactors are significantly less complex than rocket engines
“It's nuclear, but it's like significantly less complicated than a rocket engine, for example.”
Taylor: Valar Atomics will reach fifth reactor while competitors seek debt financing
“We are willing to go build reactors on equity balance sheet because that's going to allow us to prove it years ahead of anybody else, right? Where, where our competitors are still trying to convince, you know fundamentally risk averse you know, financers to fi…”
Taylor: Data centers will absolutely locate at gigawatt power sites
“And the question flips around, which is, if I have, you know, a gigawatt of power with land and fiber, is someone going to put a data center there? It's like, yes, absolutely, right?”
