Executive Summary
Uranium, the primary fuel for nuclear energy, is experiencing a resurgence in demand due to a global shift toward low-carbon and stable baseload energy sources. Over the next five years (2025–2030), uranium demand is expected to rise significantly — driven by new reactor builds in Asia, recommitment to nuclear in the West, and the structural role nuclear plays in powering data centres, industry, and decarbonisation programs. This note examines the demand outlook, cost competitiveness versus other energy sources, geological supply constraints, and the investment implications.
Global Demand Outlook 2025–2030
Key Demand Drivers
- Nuclear Expansion in Asia: China and India are leading the nuclear renaissance. China plans to increase nuclear capacity from ~55 GW (2024) to over 100 GW by 2030.
- Western Policy Shifts: The U.S., Canada, UK, and France are recommitting to nuclear as part of their net-zero strategies, including funding for small modular reactors (SMRs).
- Energy Security: Russia's invasion of Ukraine has increased demand for stable, domestic energy sources, boosting interest in nuclear globally.
- Electrification of Industry & Transport: Greater electricity demand requires reliable baseload power — nuclear is a primary candidate.

|---|---|---|
| 2025 | 68,000 | — |
| 2026 | 72,500 | +6.6% |
| 2027 | 77,800 | +7.3% |

Cost Analysis: Uranium vs Other Energy Sources
Levelized Cost of Energy (LCOE)
| Energy Source | LCOE (USD/MWh, 2024) | CapEx (USD/kW) | CO₂ Emissions (g/kWh) |
|---|---|---|---|
| Nuclear (New Build) | $80–$120 | $6,500 | 0 |
| Nuclear (SMRs) | $100–$160 (falling) | $5,000–$10,000 | 0 |
| Solar (Utility-scale) | $30–$50 | $900–$1,500 | 0 |
| Wind (Onshore) | $30–$60 | $1,300 | 0 |
| Coal | $60–$100 | $1,500 | 820 |
| Natural Gas (CCGT) | $45–$75 | $1,000 | 450 |
While capital costs for nuclear are high, uranium fuel costs are relatively low — approximately $10/MWh or 10–15% of LCOE — and highly predictable due to long-term contracting. In contrast, gas and coal are subject to commodity price volatility. This makes nuclear's operating economics more stable than it might appear from upfront capital comparisons alone.
"Nuclear's fuel cost component is so small that uranium price swings have minimal impact on electricity cost — a structural advantage over fossil fuels."
Geological Considerations: Supply Constraints
Major Global Uranium Reserves
| Country | Estimated Reserves (tons U) | Notes |
|---|---|---|
| Australia | 1.7 million | Largest reserves; political/environmental constraints limit development |
| Kazakhstan | 900,000 | World's largest producer (~43% of supply) via in-situ recovery |
| Canada | 850,000 | Athabasca Basin: highest-grade deposits globally (>20% U₃O₈); Cameco dominant |
| Russia | 500,000 | Geopolitical supply risk |
| Namibia/Niger | 400,000+ | Growing strategic importance |
Supply Constraints and Risks
- Underinvestment cycle: The decade from 2011–2021 saw major mine cutbacks following Fukushima. The structural supply deficit this created is only now beginning to resolve.
- Secondary supply diminishing: Stockpiles, downblending of warheads, and reprocessing streams are shrinking — tightening the market further.
- Financial buyers absorbing supply: The Sprott Physical Uranium Trust (SPUT) and similar funds have been removing spot uranium from circulation, reducing available supply for utilities.
- Permitting delays: ESG constraints and long regulatory timelines in the West (typically ~10 years to develop a new mine) mean supply cannot respond quickly to demand increases.
- Kazakhstan concentration risk: One country producing 43% of global supply creates significant geopolitical vulnerability — particularly given Russia's influence in the region.
Uranium's Role in the Future Energy Mix
Comparative Advantages
| Factor | Uranium (Nuclear) | Renewables | Fossil Fuels |
|---|---|---|---|
| Reliability (Baseload) | High | Low–Moderate | High |
| Emissions | Zero (operating) | Zero | High |
| Land Use | Low | High | Medium |
| Energy Density | Very High | Low | High |
| Lifecycle Waste | High (radioactive) | Low | High (CO₂) |
Uranium-fuelled nuclear energy complements intermittent renewables by providing stable, carbon-free baseload power. Solar and wind cannot provide 24/7 power at scale — nuclear can. Over the next five years, nuclear will be vital in decarbonisation strategies, offer energy independence from volatile fossil fuel imports, and provide grid reliability as ageing coal and gas plants retire.
The emergence of Small Modular Reactors (SMRs) is particularly significant — making nuclear scalable, modular, and more politically acceptable. Governments in the US, UK, Canada, and France are actively funding SMR development.
Key Risks to the Outlook
- Public sentiment and political resistance — particularly post-Fukushima — remain real constraints on nuclear expansion in some markets.
- Cost overruns and construction delays continue to plague large nuclear projects (e.g. the Vogtle Plant in the US ran massively over budget and timeline).
- Geopolitical supply chain concentration in Kazakhstan and Russia creates strategic risk that may drive costly supply chain reconfiguration.
- Long mine development lead times (~10 years) mean any supply response to the current demand surge will be delayed — potentially causing price volatility.
Global uranium demand: ~68,000 tU₃O₈ (2024) → ~95,000 tU₃O₈ (2030) · Spot price: ~$85/lb → $100–$130/lb est. · Reactors: ~440 → 500+ (including SMRs) · Nuclear share of electricity: 9.5% → 11–13% forecast.
- Uranium demand is entering a secular growth phase — global consumption projected to rise ~40% from 2025 to 2030, driven by Asia, energy security, and decarbonisation policy.
- Supply cannot easily keep pace — a decade of underinvestment, shrinking secondary supply, and long mine development lead times create a structural supply-demand gap.
- Nuclear's fuel cost component (~10% of LCOE) makes it largely insulated from uranium price swings — but utilities still have long-term purchasing incentives to lock in supply now.
- Australia holds the world's largest uranium reserves but faces political and regulatory constraints that limit near-term production growth.
- Kazakhstan's dominance (~43% of supply) is the primary geopolitical risk — any disruption would have an outsized impact on spot prices.
- SMRs represent the most promising avenue for accelerating nuclear deployment — watch for first commercial SMR plants in the US, UK, and Poland by 2030.
