📅 Jun 18, 2026 Payne Capital 18 MIN 292 VIEWS 48 SEGMENTS · 3 SPEAKERS
Everyone is talking about artificial intelligence right now. But almost no one is asking the most important question: Where is all the power going to come from? AI data centers are incredibly energy-intensive. The infrastructure being built to support this technology is going to require massive, reliable, and uninterrupted electricity. And that brings us to a surprising conclusion… Nuclear energy is quietly becoming one of the most important investment themes of the next decade. Over the last few weeks, we had the chance to sit down with James Walker, CEO of Nano Nuclear Energy (NASDAQ:...

James Walker, CEO of Nano Nuclear Energy, discussed the company's small modular reactor strategy, emphasizing mass production along a production line to achieve economies of scale. He noted a contract with the University of Illinois, where a reactor will be placed on campus, highlighting the safety profile of advanced technologies. Walker said a single reactor could cost 40-50 cents per kilowatt hour, but deploying 50 to a site could drive costs down to 9-12 cents. He mentioned discussions with Poland to replace coal substations and interest from Indonesia, the Philippines, and Thailand for island communities. Walker stated Nano is already revenue-producing through its transportation division and fuel supply chain, aiming to ship dozens of reactors by 2030, with a gigawatt project requiring 60 systems. He predicted US nuclear power could rise from 20% to high 30s or low 40s of generation.

Key takeaways

  1. Nano Nuclear aims to ship dozens of reactors annually by 2030, scaling to hundreds, with a gigawatt project requiring 60 systems.
  2. Deploying 50 reactors to one site could cut power costs to 9-12 cents per kilowatt hour, versus 40-50 cents for a single unit.
  3. US nuclear power generation could rise from 20% to high 30s or low 40s due to tech and electrification demand.
  4. Nano is already revenue-producing via its transportation division and fuel supply chain, before reactors are ready.
  5. Discussions are underway with Poland to replace coal substations and with Indonesia, the Philippines, and Thailand for island communities.

Everyone's obsessed with AI right now, but nobody's asking the one question that actually matters. Where does all the power come from? Welcome back to Pain Points of Wealth, where we cut through the noise, get to what's really driving markets. I'm Ryan Payne. I'm here with Chris Payne today, and we've got a fascinating conversation that goes way beyond the headlines. Because while Wall Street's chasing the next AI winner, there's a massive under the radar opportunity brewing in the backbone of it all, and that's energy. And not just any energy. We're talking about the next generation of nuclear power. Joining us today is James Walker, CEO of Nano Nuclear Energy, one of the most talked about names in the space, sharing how small modular reactors could transform everything from AI data centers to emerging markets around the world. This isn't just an AI story. This is a global infrastructure story, an energy independence story, and potentially one of the biggest macro investment themes in the next decade. Let's dive in.
So, you have a contract already with University of Illinois.
James Walker 1:05 ↗
We do. It's actually in the middle of a university campus, surrounded by dorm rooms, which gives you an idea of what is an acceptable level of the safety profile of the reactor and what the NRC now believes is acceptable to do because
Chris Payne 1:18 ↗
Great place for a party.
James Walker 1:19 ↗
Yes. This is why nuclear is very different to the process, like a different prospect to what you've seen in the past because you typically with a reactor like an AP1000, you have a large emergency planning zone around the system, as a security requirement, just in case of a meltdown scenario, where all civilian centers are very far removed from it. But that's not necessary with the new advanced technologies that are available that are being developed now, they can be located and they can be put in the middle of a university campus.
Chris Payne 1:49 ↗
So, I guess what is the long-term your market cap today is what, around a billion dollars?
James Walker 1:54 ↗
Yeah, like 1.3, something like that, I believe.
Chris Payne 1:58 ↗
1.3. I don't want to I'm going to miss say that's one point.
James Walker 2:00 ↗
No, it's all right. Like I I I I I I
Chris Payne 2:01 ↗
A few hundred million is important.
James Walker 2:02 ↗
It's yeah, a few hundred million is important, but it's all right. You're right. It's kind of in that ballpark.
Ryan Payne 2:07 ↗
So, let's talk economics of that. So, first off, how does this become a viable business model from, you know, going on a university with, you know, some of this being subsidized, obviously, some is for where is the inflection point? How does it become a profitable business? And if you give us more of the broad strokes, because my brother Chris likes he's a macro guy.
James Walker 2:27 ↗
One of the ideas of the industry in general, which is why I moved towards much smaller systems, was that you would create an ability to mass-produce reactor systems. And our reactor has been deliberately designed so we can produce them along a production line, and we can just keep making them.
Chris Payne 2:43 ↗
Yeah.
James Walker 2:44 ↗
The benefit of that is you get economies of scale through numbers of reactors. Whereas previously, you want to make a nuclear reactor as big as you can possibly make it.
Chris Payne 2:51 ↗
It's a one-unit structure.
James Walker 2:53 ↗
Yeah, exactly. Like make it as big as you can make it, because then you can get as much power as you can from that one system. But that model comes with its own risks, because you put all your eggs in one basket. Now, the downside of what the industry is trying to do now is that if you are deploying one reactor system, it's going to be expensive power. Because you've not achieved those economies of scale. You really start making a competitive product when you're producing many of the systems. So, how the business looks in the future is that you want to have a manufacturing operation where you're continuously producing these systems, and you're deploying them. And ideally, you want to produce many of these systems and deploy many to the same site. And the reason why I say that is the infrastructure that supports one reactor is the same infrastructure that supports 10 reactors. So, the system that will convert the thermal output of the reactor into electricity could does that for one. It can do it for 10. It would just be the same it would just be 10 reactors plugged into the one system. And you can see then how quickly the operation becomes more economic because you're not duplicating all the infrastructure per reactor system. You're putting in individual reactor cores and they are providing additional power into an existing system. And to give you some perspective, say you produce one reactor system for one site.
Chris Payne 4:21 ↗
Yes.
James Walker 4:21 ↗
And all the infrastructure is not being shared amongst other reactor systems. It's going to be expensive power. You might be looking at 40, 50 cents per kilowatt hour, something like that. It's going to be expensive. But say for instance you're deploying 50 to a site. I mean, you're starting to drive your costs down to like what? 12, 11, 10, 9 cents per kilowatt hour? Like you're really driving it right down. And then you're becoming much more cost competitive with other forms of power that are already considered quite cost competitive. But it's that economies of scale through numbers of systems that is going to be the future model of nuclear.
Chris Payne 4:58 ↗
Do you ever see like in say in 20, 30 years, this model taking over, you know, more larger utility like broadband electrical systems? And do you think that this would replace that or do you think this would always be more of a supplement?
James Walker 5:11 ↗
At the moment, I think that the demand is being driven by having off-grid base load power available to industries, heavy industry, tech industry, things like that. But for instance, we're in discussions with Poland at the moment. And to give you an example, they have all these small substations, but they're all coal. Now, they are looking to change all those out. And they're looking to go green. And so, they're looking to take all those small subsections, which are things like 30, 45 MW electric, small. They're tiny. And replace them all with nuclear. That could be an example of what countries might like to do to have a more dispersed energy system. Because at the moment you have big generations of power that are centralized and grids that arise around those things and you feed into mainline grids. The interesting thing about nuclear which no other power can provide is that you can provide a much more dispersed energy system. So, you can have a much more dispersed population and you could have independent towns that do not need to be near grid systems or have pipelines or transmission lines linked to them. So, you could create environments just by virtue of this technology that are just not possible at the moment. You won't have an independent Canadian northern wilderness town that completely supports itself and there's only a community of a few thousand people. That's completely possible now with the new nuclear systems that are being developed. So, it could be very transformative in that respect.
Chris Payne 6:40 ↗
Who would be that ideal client do you think for what your technology is being built for?
James Walker 6:44 ↗
Indonesia, the Philippines, and Thailand are looking at this technology and they're looking at it at the moment because they have large portions of their population spread across island communities and because of the way those islands it's very logistically and technologically difficult to continuously power those communities with gas pipelines, transmission lines just given where they are. So, they all subsist off diesel and it's incredibly expensive because diesel needs to be brought in on a daily basis and that also causes periodic blackouts, insufficient power. And if you were to install these reactor systems into these locations, suddenly they've got consistent power and all the logistics and the costs around diesel and subsisting off diesel go away. And these locations become more independent. That's going to be a very interesting flagship project to build out power for those kind of environments. And that's going to mean hundreds of reactors, thousands of reactors across these kind of communities.
