Global nuclear expansion is colliding with a uranium supply chain built for a different era.
According to Bloomberg, reactor capacity is expected to increase 44% over the next decade. Such growth is bringing a wave of fuel demand that begins well before new plants generate a single watt.
A 1-gigawatt reactor needs around 400 metric tons of uranium for its initial core load, and then about 160 tons annually thereafter. Thus, just first loads for reactors currently planned would consume uranium equivalent to nearly 90% of current annual global mine output.
That front-loaded requirement is intensifying a deficit that emerged in 2018 and has continued to widen. Goldman Sachs forecasts a cumulative shortfall of about 2.3 billion pounds of uranium oxide (U₃O₈) between 2025 and 2045, as AI data centers, electrification, and industrial reshoring lift demand for reliable baseload power.
Long-Term Prices Signal Utility Anxiety
The divide between uranium's physical market and its equities has become increasingly pronounced. Uranium mining shares fell during the first half of the year even as the long-term uranium price climbed to $94 a pound at the end of June – near the highs of the last two decades.
That term price matters more than daily spot-market moves because it reflects the contracts utilities use to secure fuel years in advance, as well as the incentive price required to finance new mines.
"A rising long-term price shows that the market remains tight, even if equity markets don't reflect it," Jacob White, Sprott's ETF product manager, wrote in a recent analysis.
White argues that recent weakness in uranium miners reflects broader risk-off sentiment, rather than a deterioration in fuel-market fundamentals. Spot uranium rose 4.3% in the first half, while uranium mining equities declined 3.9% and junior miners fell 7.4%, according to the firm.
Supply Can't Simply Catch Up
Higher prices have encouraged producers to consider restarting idled capacity, but building new supply remains a slow, expensive and uncertain undertaking. Large deposits require years of permitting, financing, construction and technical execution before they can add meaningful production.
Meanwhile, utilities have under-contracted for more than a decade, drawing down secondary inventories that once helped bridge the gap between mine production and reactor requirements.
Government policy is moving faster. The U.S. Department of Energy announced $17.5 billion in conditional loans for long-lead items for up to 10 reactors. Canada's new Nuclear Energy Strategy supports reactor construction, fuel-cycle investment and expanded uranium exports. China, the world's largest nuclear builder, accounts for 38 of the 79 reactors under construction globally, according to figures cited by Sprott.
