MacroVoices #554 Yasir Arafat: Mass Manufacturing Nuclear Power Plants

Oklo

• Erik Townsend · MacroVoicesBullish

  Oklo's planned 1 GW/yr is woefully insufficient for near-term AI data center demand.

  Erik says he has done the arithmetic and sees considerably more demand from AI data centers alone over the next few years than the 1 GW a year Oklo's factory under construction in Texas would supply (about 100 reactors at 10 MW each). Critics view that as overkill, but he thinks it will be woefully insufficient. He also argues that replacing fossil fuel energy would require far more output: at 1 GW a year it would take about 9,000 years, and a 25% share would require about 112 GW a year. He discloses that he is an early investor in Oklo and that it is his largest private equity position.

  “I think there's already considerably more demand just from the AI data centers alone over the next few years... some critics think that's overkill. I think it's going to be woefully insufficient.”at 8:53

Centrus Energy

• Patrick Ceresna · Big Picture TradingBullish

  Centrus is a long-term nuclear fuel supply play; selling a discounted put offers a 14.6% premium.

  Ceresna argues nuclear buildout depends on fuel supply, and Centrus supplies enriched uranium and is expanding domestic enrichment for existing and advanced reactors. He sees a long-term investment case in secure fuel supply. The stock is under heavy selling pressure, and implied volatility is elevated, so he proposes selling a January put with a $70 strike, about 43% below the current price of around $122, with roughly 464 days to expiry. The midpoint premium is about $10.25 per share, or $1,025 per contract. If assigned, the adjusted cost base would be about $60, roughly 50% below the reference price. If the put expires, the premium is a 14.6% return on the obligation. He says the maximum profit is the premium and that losses remain possible, so position size should reflect the ability to fund the full share purchase.

  “The company supplies enriched uranium and is expanding domestic enrichment capacity for both existing reactors and advanced designs. That creates a long term investment thesis around nuclear growth”at 58:24

• Patrick Ceresna · Big Picture TradingBearish

  CoreWeave's bond stress shows AI growth is financed by credit that may dry up, risking a slowdown.

  Ceresna cites CoreWeave shares falling close to 16% in one session while its outstanding bond yields rose to about 15%, pushing the bonds to junk status. He argues this is less about CoreWeave's size and more about AI absorbing large amounts of credit to fund growth. He says growth will potentially stall once access to that credit slows. He frames the event as possibly the first sign that the financing cycle is becoming stressed. He is not calling a definitive top, but says it shows the market is starting to test when credit for AI stories dries up.

  “AI has been sucking up so much credit in order to create growth. And inevitably, the growth will start to potentially stall when their access to credit also slows.”at 1:01:51

Nuclear energy

  Oklo customers are reserving large shares of factory capacity, a demand signal for a second factory.

  Yasir says prospective customers are not asking for one to ten reactors but to reserve 20% of the factory's production capacity. He describes a model in which three more customers each take the next 20%, reaching 80% utilisation, and that this demand would signal the need to build a second factory. Oklo is expanding from a 40,000 sq ft facility to about a million sq ft to produce 100 reactors a year.

  “They're asking us literally like, hey, I want to reserve 20% of your factory production capacity.”at 7:32

• Erik Townsend · MacroVoices

  Demand for nuclear would explode once it costs less than coal and gas and deploys as fast.

  Erik argues the key threshold is making safe, clean nuclear cost less than coal and gas and deployable as quickly. Because the whole world wants to move off fossil fuels, demand would surge immediately once that is achieved. Today nuclear costs about twice as much as coal and gas, takes about ten years to build, and is hard to finance. A modular plant built on an assembly line for less than a coal plant would be a 'nuclear Henry Ford moment' that could break humanity's addiction to fossil fuels. Erik says this is a long-term view and not something he expects in the next few years.

  “when somebody figures out to make safe, clean nuclear energy cost less than coal and gas and be deployed just as quickly, I contend demand explodes overnight”at 17:31

• Yasir Arafat · Aalo Atomics

  Supply chain, not manufacturing, is the biggest challenge to scaling reactor production.

  Yasir says a one-off reactor is manageable and that his team's manufacturing capability can build about 20 reactors a year. Scaling to 50, 100, 200 or 300 will break parts of the supply chain. Oklo relies on about 230 vendors for steel, pipe, sensors and electronic components, and that number is growing. The hard question is how to get suppliers to invest in capacity so they can grow alongside Oklo. He says the company is confident this is solvable, and that the team includes former Tesla volume-production engineers.

  “Because manufacturing is really not the biggest problem here alone. The biggest problem here is supply chain.”at 24:23

• Erik Townsend · MacroVoices

  Structural enriched-uranium supply deficit is coming in the 2030s, especially for HALEU.

  Erik says uranium is cheap today, under $100 a pound, but that will change in the next few years. Centrifuge enrichment plants cost almost as much as oil refineries and take almost as long to build and bring online. Every uranium expert he has interviewed agrees there is a structural supply deficit in the 2030s, before any mass production of reactors. The deficit would be most acute in the HALEU market now forming. He concludes that scaling to hundreds of gigawatts a year would be hard without a smarter approach to enriched fuel.

  “Every uranium expert that I've ever interviewed on this program seems to agree that there's a structural supply deficit coming in the twenty thirties, not for a few years, but in the twenty thirties”at 27:20

• Yasir Arafat · Aalo Atomics

  Uranium is abundant; 30% of known reserves tapped, and recycling extends supply to about 12,000 years.

  Yasir argues uranium supply is not as constrained as commonly assumed. Uranium is abundant in the soil and found alongside iron, copper and lithium. Of the identified mines that can be tapped, only about 30% of known reserves are in use, leaving about two-thirds, enough for roughly 117 years of current-style plants. Burning 5% enriched fuel leaves about 95% reusable material, and recycling it extends the identified supply to about 12,000 years. On this basis he says oil and gas last about 50 years for civilisation, while nuclear could last close to 120 years, so the question is when the transition happens rather than whether it does.

  “Uranium is very abundant in the soil, but every single mine that [we've] identified right now that we can tap into for uranium, we've actually just tapped into 30% of that known reserves of uranium in the mine.”at 32:38

• Yasir Arafat · Aalo Atomics

  Building fast-spectrum reactors on day one is a mistake without a fuel supply chain.

  Yasir distinguishes Oklo's approach from some peers who are working on fast-spectrum reactors from the start. He says that approach is a mistake because the fuel supply chain for it is not ready, and those designs would wait many years for the supply chain and costs to come down. Oklo's plan is to run on LEU for near-term cost reduction, then move to fast-spectrum reactors when HALEU becomes available in large enough quantities. Fast-spectrum designs could burn far more of the fuel and cut mined uranium use.

  “Now some of our peers are still working on fast spectrum reactors on day one, which I think is a mistake, because we don't have the supply chain.”at 35:14

  Spent nuclear fuel is wasted energy; reprocessing and burning it is the answer.

  Erik says the world has about 250,000 metric tons of spent nuclear fuel in storage and that public fear of it is misplaced. He argues the real problem is wasting perfectly good fuel. Reactor designs from before he was born can burn this material after reprocessing, so the answer is to stop calling it waste, use it as fuel, and build reactors that can burn it.

  “What I had no idea of is the crime here is wasting that perfectly good nuclear fuel.”at 36:23

• Yasir Arafat · Aalo Atomics

  Used nuclear fuel is recoverable and recyclable, so it is a resource rather than a dangerous waste problem.

  Arafat argues the 'nuclear waste' problem is a myth. Spent fuel is called used nuclear fuel in the industry because most of it can be recovered and reused in reactors, and fast-spectrum reactors can extract far more energy from it. He says the solid, concentrated form is an advantage: it keeps CO2-style sequestration problems out of water and air, and no person or plant has been affected by commercial spent fuel. Recycling it could unlock much more energy. He says the nuclear industry has done a poor job explaining this to the public.

  “And nuclear waste is not a real waste. It's actually what we call in the industry used nuclear fuel or spent nuclear fuel. And the reason why we don't call it a waste is because the majority of this material is recoverable and reusable”at 37:49

• Erik Townsend · MacroVoices

  Reprocessing spent fuel is proven viable, so shelving it for disposal is a policy failure.

  Townsend argues that skeptics should look at the history. The US built a reprocessing facility in the 1970s, but President Carter ordered it shut down just before it was ready, because the issue became politicized. He says the UK has shown reprocessing works: it recovered a large quantity of reactor-grade plutonium that can be burned as fuel as effectively as the HALEU that the US struggles to source. The UK government then decided to spend billions of pounds disposing of that valuable material underground. He presents this as wasteful policy rather than a technical barrier.

  “they proved that you can reprocess it and get it to something that can burn in a reactor.”at 42:23

• Yasir Arafat · Aalo Atomics

  US nuclear policy has turned supportive under this administration, unlocking fuel recycling and the NLIC campuses.

  Arafat says the technology for recycling used fuel and making fresh fuel for fast-spectrum reactors is proven and demonstrated in the US and abroad, so the remaining barrier is policy, which is in limbo. Previous administrations avoided taking clear positions on nuclear, while this administration has been vocal in support and put strong advocates such as Energy Secretary Chris Wright in top roles. Wright is working to bring back the idea that the US should recycle used fuel and let startups build industries around it. He points to the Nuclear Lifecycle Innovation (NLIC) campus program, where the government will pick two host states for facilities covering mining, enrichment, fuel fabrication, reactors and recycling. He expects this to attract public and private investment and jobs.

  “all that I think has changed with this administration, who have been extremely vocal about their support in nuclear”at 44:39

• Yasir Arafat · Aalo Atomics

  China is a formidable rival but mostly copies US nuclear designs and is weak at first-of-a-kind technology.

  Arafat concedes China is a formidable competitor that has outcompeted the US in many industries. He argues that in nuclear, every advanced reactor China has built is a design the US developed first, mostly as prototypes at national labs such as Idaho National Laboratory. He cites China's pebble-bed gas-cooled reactor, which reached operation before the US version, but says it has had ongoing operating problems. He concludes that China copies and executes well, but is not strong at new first-of-a-kind technology. He also cites Apple, Tesla's Model Y and US jet engines as evidence that money and manpower alone do not guarantee faster innovation. He says the US must keep innovating and clear policy bottlenecks, since losing to China is only certain if the US does nothing.

  “they're copying off of what The United States have already done. ... They're not very good at coming up with brand new technology. They're good at copying other innovations”at 52:43

• Erik Townsend · MacroVoices

  China's state-funded nuclear buildout threatens US competitiveness and energy security unless US policy acts.

  Townsend argues the main competitor for advanced nuclear is China, not another reactor company. China has a state-funded plan to outspend the sector and already has more light-water reactors planned or under construction than the entire US fleet. It has built a high-temperature gas-cooled reactor and has announced thorium molten-salt reactors for container ships. He thinks China is likely to move into factory mass production of these designs, which is the path Aalo is pursuing. He says the technology was invented in the US, so a competitive disadvantage is forming, and that the energy security of the US is at stake. He conditions the outcome on whether US policy prioritizes the steps Chris Wright has started.

  “China is set to win if we don't take policy action to put more priority on doing the things that Chris Wright has already set out”at 56:18

Power demand & the grid

• Yasir Arafat · Aalo Atomics

  Data centers need about 125 GW by 2030, but the grid can supply only about 25 GW, a 100 GW gap.

  Yasir cites Bank of America's estimate that AI data centers need about 125 GW between 2026 and 2030, and he says each gigawatt powers about a million homes. He believes the grid and other suppliers can pull together only about 25 GW, leaving a roughly 100 GW generation gap. He says this is why the data center market is so large and why reliable on-site power matters, since grid strain would make data centers a burden on communities.

  “Bank of America, for example, they said, hey. We need a 125 gigawatts... from this year to 2030, we need 125 gigawatts. And right now, I believe the grid and everybody else, they can pull together about 25 gigawatt or so.”at 12:49

• Yasir Arafat · Aalo Atomics

  Gas turbines will become obsolete once nuclear volume production drives costs down.

  Yasir argues that once volume production brings costs down far enough, nuclear reactors become an almost obvious choice for power, and gas turbines will become obsolete. The argument depends on his own cost projections: first-of-a-kind power in the mid-teens cents per kWh falling below 10 cents with volume, and reaching parity with coal and gas.

  “when we unlock the volume production, costs will come down so low, then this technology will become almost a no brainer to go after. At that point, gas turbines will truly become obsolete”at 25:09

US stock market outlook

• Patrick Ceresna · Big Picture Trading

  Money is rotating from Nasdaq AI names into defensives, but one day is not yet a confirmed trend.

  Ceresna notes that money had been flowing heavily into the Nasdaq, with commitment-of-traders positioning in the Nasdaq at the 100th percentile while Russell small caps sat near the zero percentile. The day after the hot CPI print, defensive sectors such as utilities, consumer staples and healthcare advanced along with bonds, while many AI-driven names pulled back. He says one day does not make a new trend, but the rotation could signal a bigger sector rotation. He is watching whether beaten-down sectors rebound and whether CTA and systematic sell triggers on the Nasdaq and S&P 500 force deleveraging.

  “Yesterday, all the defensives were ripping higher, including bonds. We had basically utilities, consumer staples, healthcare, all advancing, while we basically saw very strong pullbacks in almost all of the AI driven names.”at 1:03:42

US Treasuries & yields

• Patrick Ceresna · Big Picture Trading

  Treasuries are acting as a defensive asset as rate-hike pricing fades and risk-off pressure builds.

  Ceresna sees the bond market move after a hot CPI print: yields rose early, then the 10-year and 30-year reversed about 25 basis points from peak to trough. He says the reversal is an intermarket signal at an inflection point. The December 2027 SOFR contract appears to have double-bottomed and turned as the market began taking rate hikes off the table over the next year. Combined with widening junk-bond spreads, this points to a risk-off scare in which Treasuries may be the defensive asset. He is watching whether these signals follow through.

  “There's further evidence that there's some sort of a risk off scare occurring and potentially treasury bonds may be a defensive asset in this period.”at 1:06:15

US dollar

• Patrick Ceresna · Big Picture Trading

  The dollar remains in a primary bull trend, with a pullback toward 101 possible but dips still bought.

  Ceresna says the US dollar index hit a higher high near 103 on the hot CPI print, then pulled back the next morning. He describes the dollar as still in a primary bull trend. He notes the index could easily absorb a pullback toward 101. He says it is too early to conclude that intermarket signals will pressure dollar flows. As long as dips continue to be bought, he would still consider the trend a clean bull market.

  “The dollar index could easily absorb a pullback down towards one zero one. But so long as dips are being bought, I would still consider technically in a clean bull trend.”at 1:07:06

Oil & fuels

• Patrick Ceresna · Big Picture Trading

  Crude fundamentals are strong and shorts are crowded, so WTI's front month looks held down and vulnerable.

  Ceresna argues crude is structurally strong in Brent and other markets, while the WTI front-month contract has stayed in consolidation. The oil curve shows backwardation flattening: the front month is about 6% below its September 15 highs, while the April contract is up about 10%. Commitment-of-traders data shows gross short positioning in crude futures at multiyear extremes, which he thinks may be holding the front month down. He adds that the Strait of Hormuz situation looks as tense as it has been in a long time, and inventories are depleted. He questions how long the front month can stay contained.

  “we see structurally strong crude oil markets in Brent and in so many other parts of the oil markets, but the WTI contract remains somewhat in consolidation.”at 1:07:25

Gold & precious metals

• Patrick Ceresna · Big Picture Trading

  Gold could turn bullish if yields fall and the Fed is priced to ease in 2027, but no confirmation yet.

  Ceresna says gold has consolidated back to its previous lows near the $4,000 level. If bond yields fall and growth expectations are curtailed, markets may start pricing a Fed that has to be much easier in 2027, which would make conditions bullish for gold. Gold is rising in premarket trading, but he has not yet seen a trendline break or a close above key moving averages. He says there is a case for a bottom, but the price has not reflected it yet, so he will watch whether support holds.

  “Now if this starts to materialize, the conditions may actually become bullish for gold.”at 1:09:41
