why aren't all 13 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 2 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable

Bernauer: Town diesel power causes 12 premature deaths over 20 years
“And if you look at what happens in a town over 20 years of span if you pick a diesel genset instead of a reactor there's something like 12, ah, deaths that are going to occur prematurely from the use of diesel.”

Opinion
Bernauer: Nuclear is the only viable way to power Mars fuel production
“And so I looked into solar power on Mars and found that was really challenging, and then I looked into nuclear power on Mars and found that was the only way.”

Insight
Bernauer: Deployable and retrievable nuclear reactors require sizing around 1 MW
“It's only possible if you make a size about one megawatt, right? Make a small enough reactor, you can do this, transport it there and back again sort of trick, and take the fuel back, and so you have, like, no nuclear strings attached.”

Prediction Open · timeframe Dec 2026
Radiant will achieve reactor criticality and 700°C operations by 2026
“Since 2020, we've been on target for going there by 20, 26, and then we'll go critical. The system is designed to go to over 700 degrees Celsius, and then we'll run for 150 hours continuously.”

Prediction Not checkable as stated
Bernauer: Mass-produced micro-reactors will enable interstellar human travel
“Nuclear micro-reactors that are mass-produced, that are reliable in the most wild scenario enables humans to leave the star that we were born at, the sun, and go to other ones.”

Assertion Supported
Bernauer: Large reactor builds are far slower in US than Asia
“And the typical construction timeline is really like six to 15 years on the big reactors right now, depending who makes them, even for the exact same reactor, like an AP 1000, built in the US is very slow, built in Asia is very fast.”

Prediction Open · timeframe Dec 2026
Bernauer: Radiant targets 2026 field demonstration for microreactor
“Our timeline has not changed since we started the company in twenty-twenty. We want to do a field demonstration in twenty-twenty-six.”

Disclosure
Doug Bernauer: Radiant Focuses on Building Reactors, Not Reactor Buildings
“What we want to be doing is building reactors, not reactor buildings.”

Prediction Not checkable as stated
Bernauer: Nuclear energy will leapfrog natural gas
“Natural gas, which I agree with Dr. Huff the low cost of it definitely caused us to adopt that, to fill that need, rather than nuclear, but I think nuclear can leapfrog it.”

Opinion
Bernauer: Federal microreactor demonstration program is key to commercialization
“I think a real micro-reactor demonstration program from the federal side would probably be the single biggest thing we could do to accelerate our efforts to commercialization.”

Assertion Partly supported
Bernauer: INL Built 52 Reactors by 1977 and None Since
“There were actually 52 nuclear reactors built at Idaho National Laboratory in a 21 year span, the last of which was in 1977, and none since then.”

Assertion Supported
Bernauer: US once had over 400 operating uranium mines
“I think we had over 400 uranium mines operating in the US and really we were the great developers and exporters of our technology to the rest of the world”
