speaking balance: gold is Joe, purple is the guest (3 minute bins)
Sharpest disagreement ▶ 28:45 Direct pushback on regulatory compliance
When Joe jokingly implies Scott is forced to praise the Nuclear Regulatory Commission for licensing favors, Scott firmly rejects the assertion with an immediate 'No, absolutely not' and provides historical context.

| Government Support, $900M DOE Award, and Global Geopolitics | 5 | 6 | 1 | 2 | Scott details General Matter's $900M milestone-based DOE contract and EXIM Bank partnerships to counter Russian and Chinese influence in allied nations. Joe asks why they don't expand into full utility operations, prompting Scott to cite Peter Thiel's Zero to One philosophy. | |
| Space Nuclear Power, Energy Abundance, and America's Future | 4 | 4 | 1 | 1 | The conversation moves to future frontier applications, including space propulsion and moon base power, before concluding with an optimistic outlook for America's semi-quincentennial. Both exchange visionary scenarios of energy abundance. |
Statements from this episode (20)
Nolan: Boeing's slow cost-plus programs drove him to join SpaceX
“Got to work at Boeing during college, got to see what a cost-plus government program looked like, thousands of people going extremely slow, decided I didn't want to do that, Didn't want to go back to Boeing, instead went to SpaceX”
Nolan: Early SpaceX employee handbook declared this is not a science experiment
“I remember getting there on day one and reading the employee handbook and on the top of page one was just a single line that was in bold. And it said this is not a science experiment.”
Nolan: Expediting critical-path projects pays off if cheaper than daily burn
“If you're on the critical path of schedule and you can make a one-time decision to pull in schedule by a day, like you can expedite something that's otherwise going to make us have to exist as a company for two more days, five more days, and it's worth less, i…”
Nolan: SpaceX can be cash-flow positive whenever it wants to be
“I think now the company, you know, has money and can be cashflow positive whenever they want to be.”
Nolan: Small Advanced Reactors Require Enrichment up to 19.75% U-235
“Most reactors, the big ones, people think about gigawatt scale reactors. They need that you, the uranium enriched to about three to five percent U two 35. And then the small ones, 19.75% is where everyone's ending up”
Nolan: Nuclear energy has the lowest death rate of any baseload power
“Nuclear energy for the past 50 years has been the cleanest form of energy, no carbon emissions, the safest form of baseload, which people find really surprising, but fewer human deaths per terawatt hour than any other baseload, And even any other energy source…”
Nolan: A single nuclear pellet equals over 100 barrels of oil
“One of those pellets is equivalent to over a hundred barrels of oil or over a ton of coal.”
Nolan: Fuel can exceed half the operating cost for small advanced reactors
“And so you go from a situation where the reactor is over 90% of total cost of energy produced to where, and fuel is obviously single digit percentages with low enriched uranium and gigawatt scale reactors and those simple metal fuel pellets to now where the fu…”
Nolan: Uranium enrichment is the only nuclear step the US lacks domestically
“The reason we're doing enrichment is because that's the one step the US doesn't do at any scale.”
Nolan: US Accounted for Over 80% of Global Uranium Enrichment in 1980s
“So the US in the eighties was actually more than 80% of global enrichment.”
Nolan: General Matter is building on the last closed US enrichment site
“And we shut down the last enrichment site in 2013, and that site was actually in western Kentucky on DOE land that our company is now building on.”
Lonsdale: Musk fears US power shortages and is impressed by China's output
“We actually, I was with Elon recently. He was here, and his, one of his big concerns for the US was not having enough power. He's very impressed by how much power China's making overall.”
Lonsdale: Russia funded European green parties to halt fracking and eliminate competition
“They funded the green parties, they funded the protests, and they turned off fracking in Europe because it's so good for the environment. They tricked everyone because obviously they don't want competition.”
Nolan: China has tripled its electricity grid capacity since 2010
“If you look at the grid in 2010, we were completely tied neck and neck with China on grid total capacity. Something like 4000 or 5000 terawatt hours per year. Since then, in the 15 years since 2010, they've tripled. I think this year they're actually at three …”
Nolan: Advanced nuclear reactor deployments will ramp significantly starting in 2030
“That, I think those, that timing is coming, you know, 20, 28 through 20 30. They're gonna first really start doing the, you know, single digit deployments, and then I think 2030 is where it really ramps.”
Nolan: NRC committed to fast-tracking new fuel cycle licenses to 12 months
“And I think it was Thursday the NRC announced that a new fuel cycle license application went in And they're committing to put it on fast track and get it out in 12 months.”
Nolan: General Matter won a massive DOE contract for HALEU uranium enrichment
“Congress that appropriated 2.7 billion dollars for HALU enrichment. And we received one of those awards for nine hundred million. So nine hundred million dollar Milestone based contract, which will be earned over the next few years as we build that capability …”
Nolan: Allied nuclear fleets will rely on Russia and China without US
“If the U.S. Does not provide enrichment To these countries, they will have to get it somewhere else as they build up their nuclear fleet, or they turn back on their nuclear fleet, and that'll be Russia, China.”
Nolan: NASA aims to achieve nuclear-driven space propulsion by 2028
“I think they're aiming for space ion nuclear-driven space propulsion by twenty-twenty-eight. And then they're talking about reactors on, on the moon's surface to, you know, create heat and power things.”
Nolan: Factory-built nuclear energy should drop below 3 cents per kilowatt-hour
“I think three cents shouldn't even be the limit. Like that was three cents building huge gigawatt scale mega construction projects, not factory production. And so I think we should physically be able to get less than three cents if we were doing it before.”
