Canaccord's first Nuclear Nexus conference mapped three hard constraints: HALEU supply, Western cost doubling, and regulatory timelines that could delay AI data center power.
Canaccord Genuity's first Nuclear Nexus conference gathered fission and fusion developers, academics, and investors to confront a shared problem: surging electricity demand from AI data centers "finds itself bottle-necked by the physical reality of the grid." The report from the event maps three hard constraints – HALEU supply, Western cost disadvantages, and regulatory timelines – that will determine which nuclear projects deliver power this decade and which slip.
Oklo CEO Jacob DeWitte stressed that securing a domestic HALEU supply chain through Idaho National Laboratory and Centrus is critical for the company's Aurora Powerhouse fast reactor. Without that fuel stream, advanced reactor designs cannot scale. Longer-term options include spent fuel reprocessing and access to government plutonium reserves suited to fast reactor designs, though those pathways require policy changes and years of development.
Newcleo is advancing lead-cooled fast reactors with MOX fuel and has partnered with Oklo to establish a U.S. MOX fabrication capability, addressing the domestic prohibition on commercial plutonium reprocessing. That partnership is one of the few near-term efforts to reduce enrichment dependence, yet it faces regulatory and public acceptance hurdles.
ASP Isotopes is commercializing laser-based enrichment, and SHINE Technologies is generating near-term revenue from isotope production and fusion-fission hybrids. Neither addresses the immediate enrichment gap facing Western reactor operators.
On the fusion side, UK Atomic Energy Authority's Mike Gorley described fusion as fundamentally a large-scale thermal engineering problem rather than pure physics. He flagged a global shortage of Lithium-6, essential for tritium breeding and reactor performance. That input problem makes fusion timelines even more speculative, with no near-term solution visible.
MIT professor Jacopo Buongiorno highlighted that the lack of recent construction experience in the West has roughly doubled nuclear build costs compared with earlier decades. Small modular reactors are more likely to provide financing flexibility than dramatically lower electricity costs. He pointed to HALEU supply as a critical chokepoint that will not resolve quickly.
The contrast with rapid expansion in Asia and continued Russian export dominance was presented as a structural challenge rather than a temporary setback. Russia remains a major supplier of enriched uranium. Western efforts to build independent fuel supply chains will take years, leaving operators exposed to geopolitical risk and price spikes.
TerraPower, backed by Bill Gates, received a landmark NRC construction permit in March 2026 for its Natrium sodium-cooled fast reactor in Wyoming. The company is on track for a 2030 startup and has signed a major agreement with Meta to develop up to eight additional Natrium units capable of supplying 4 GW of dispatchable power to data centers.
NuScale and its development partner ENTRA1 are advancing a six-plant deployment across Tennessee Valley Authority territory, with four sites already identified.
Terra Innovatum's SOLO microreactor is designed to run on either LEU or HALEU and incorporates inherent safety features that eliminate meltdown and explosion risks. The company is targeting a first-of-a-kind demonstration in 2027 and commercial units in 2028 under the NRC's proposed Part 57 microreactor framework.
Inertia is pursuing inertial confinement fusion and plans to begin construction of a 1.5 GW grid-scale plant in 2030 after solving manufacturing challenges for high-efficiency lasers and fuel targets.
Zap Energy is running a dual-track program pairing a Z-pinch fusion reactor with a simpler sodium-cooled fission microreactor, planning to deploy the lower-risk fission technology in the early 2030s before scaling fusion later in the decade.
MIT professors Dennis Whyte and Andrew Lo described their new Rutherford Energy Ventures vehicle as a diversified portfolio approach across the fusion value chain. They cited easier regulatory pathways for fusion compared with fission and immediate revenue potential from spin-off technologies.
The Meta agreement with TerraPower is the most concrete signal that hyperscaler demand is driving nuclear procurement. 4 GW of dispatchable power from Natrium reactors would serve multiple data-center campuses. If TerraPower hits its 2030 deadline, other hyperscalers will likely follow. Participants noted that Google and other hyperscalers provide early demand signals that could accelerate regulatory and financial commitment.
Elementl framed itself as a technology-agnostic integrator focused on scaling proven light-water reactor projects to 100 GW by 2040. The firm leverages hyperscaler offtake agreements to de-risk project financing.
Panels on critical materials and isotopes pointed to persistent supply constraints for both medical isotopes and nuclear fuel components. Uranium Energy Corp (UEC) is positioning its U.S.-focused uranium assets against a projected 1.9-billion-pound market deficit. That deficit reflects years of underinvestment in mining and conversion capacity, compounded by long permitting timelines. The gap between projected demand and deliverable supply is the single largest structural risk for the sector.
On the UEC stock page, Uranium Energy Corp remains Unscored under the AlphaScala system, reflecting the sector's early-stage uncertainty. Traders should monitor the company's progress in securing offtake agreements and permitting for U.S. assets as the deficit creates pricing leverage.
The report leaves the impression that the nuclear sector is entering a more dynamic period. The transition remains defined by practical constraints on fuel, regulation, and execution speed. Watch NRC permits, HALEU contracts, and hyperscaler offtake agreements as the next catalysts. For broader context, see the commodities analysis and coverage of nuclear fuel cycle gains.
