China's 36-Reactor Pipeline Claims Half of Global Nuclear Construction
Beijing's under-construction queue, at 49% of world capacity additions, is the only build programme large enough to shift its 2030 non-fossil power target.
China commissioned two reactors in the first five months of 2026, Sanao-1 and Taipingling-1, and now holds 36 units under construction across 19 sites, the IAEA's Power Reactor Information System shows. Those 36 units account for more than 49% of all nuclear construction worldwide.1
The scale of that pipeline is what makes it consequential for energy markets. When the 36 reactors come online they will add about 38.9 GW of capacity, against an existing Chinese fleet of 60 operational reactors and 58.7 GW installed at 18 sites as of May 2026, per PRIS data. The under-construction queue is roughly two-thirds the size of what already runs.1
The build-out sits behind a specific national commitment. China's National Energy Administration and National Development and Reform Commission announced in the week of 2026-06-22 a plan to generate 50% of the country's electricity from non-fossil sources by 2030. Nuclear earns its place in that target because it delivers baseload at high utilisation, which intermittent wind and solar cannot guarantee.2
Yet nuclear still accounted for only about 3.3% of China's total energy supply in 2025, despite the country ranking as the world's second-largest nuclear generator, according to Forbes data. France drew about 47% of its energy supply from nuclear in the same year; the US about 9.6%. The gap between China's reactor count and its energy-mix share reflects the sheer size of Chinese electricity demand.4
The growth rate has been fast regardless. China's nuclear generation capacity rose 76%, or 24 GW, between 2016 and 2024, EIA data show. PRIS records a further 1.1 GW added in 2025 and 2.2 GW through May 2026 alone.1
That pace contrasts sharply with the US position. Washington operates 96 commercial reactors across 57 plants in 28 states, producing about one-third of global nuclear output, according to oilprice.com. But the fleet is ageing, and new-build has stalled. The federal government announced over $17 billion in loans to encourage nuclear investment, targeting a power deficit tied to the AI build-out; analysts quoted by oilprice.com argued the programme does not fix the underlying supply-chain problems.7,3
For coal traders the operational question is displacement. Each large Chinese reactor that enters service removes baseload coal burn from the coastal grid, where imported thermal coal competes directly. Newcastle physical coal closed at $137.05/t on 2026-09-20's session, a price still consistent with sustained seaborne demand from Asia. The pace of Chinese reactor commissioning is the variable that determines how long that demand picture holds.2
Beijing is extending the model beyond its borders. Following the launch of its 15th Five-Year Plan in March 2026, the government published sectoral plans through end-June including a New-type Energy System blueprint, and is actively contesting nuclear export markets in Southeast Asia against US interests.6
Domestic equity markets have already moved. China's A-share nuclear power index has risen more than 100% cumulatively over the past two years, outperforming hydropower, thermal power and new energy sub-sectors, per 36kr. The URA uranium ETF closed at $41.65 on 2026-09-20, down 2.94% on the session. The divergence between buoyant Chinese nuclear equities and a softer uranium ETF reflects different time horizons: fuel demand from 36 reactors builds over years, not quarters.5,7
Inside the main programme sits a separate technology contest. China is building the Linglong-1, its first small modular reactor — a domestically designed 100 MWe pressurised water unit intended for power generation, desalination and district heat. If it delivers, China enters the SMR export market before most Western designs complete licensing.1
The IEA's characterisation of a global nuclear renaissance is real, but geographically concentrated. Asia more than doubled nuclear output and now produces almost 30% of the world's nuclear electricity, Forbes reported. Still, nuclear's share of global energy supply edged down from 5.19% to 5.17% over the same period, because total demand grew faster.4
China can add 38.9 GW of reactors and still see nuclear's share of its own energy mix rise only slowly, given electricity demand expanding fast enough to absorb every megawatt of new baseload. The reactors reduce the growth rate of coal burn rather than reversing it outright. The commissioning schedule — whether the 36 units under construction convert to grid connection on PRIS-implied timelines — is the number worth tracking. Slippage there leaves the 2030 non-fossil target more exposed to wind and solar capacity factors than Beijing's planners appear to be pricing in.1,2
