China Doubles Down on Nuclear Power

China is building more than half the world’s reactors under construction while the US revives nuclear investment and Germany lives with the consequences of its phaseout.

China Doubles Down on Nuclear Power

China is building nuclear reactors at a pace no other country currently matches. More than half of the reactors under construction worldwide are in China, and some projections suggest its nuclear output or capacity could roughly double over the next decade.

The contrast with Germany is politically irresistible: Berlin closed its last nuclear plants in 2023, while China and the United States treat atomic power as part of energy security and the electricity demand created by artificial intelligence.

But the conclusion is more complicated than “nuclear wins, renewables fail.”

China’s nuclear strategy

Beijing wants reliable, low-carbon electricity, less dependence on imported fuel and a domestic industrial base capable of exporting reactors. Nuclear plants provide steady output that complements China’s enormous wind and solar buildout.

The country is also investing in small modular reactors and fusion research. State finance, standardized designs, supply chains and centralized planning allow projects to move faster than in many Western markets.

That advantage is real, though not costless. Nuclear construction requires high upfront investment, strong regulation, waste management, water and long timelines. Rapid expansion makes quality control and institutional independence essential.

The US revival

The United States still operates the world’s largest nuclear fleet by output. Recent policy supports license extensions, advanced reactors, fuel supply and the reopening or preservation of plants that might otherwise close.

AI data centers add pressure for round-the-clock power. Technology companies are signing nuclear contracts because intermittent generation alone does not always match constant computing demand without storage, transmission and backup.

The American challenge is delivery. New large reactors have suffered delays and cost overruns, while permitting, workforce and supply-chain constraints slow expansion. Announcing a nuclear renaissance is easier than completing one.

Germany’s different bet

Germany’s nuclear exit reflected decades of anti-nuclear politics, safety concerns intensified by Fukushima and a policy choice to prioritize renewables. The timing became more controversial when Russian gas supplies collapsed and industrial electricity costs rose.

Critics say closing functioning low-carbon reactors increased reliance on coal, imports and expensive balancing. Supporters answer that nuclear’s share could be replaced through renewables, grids, storage and efficiency, and that keeping aging plants open would not solve every price problem.

Both claims contain part of the picture. German energy costs also reflect gas markets, taxes, network charges and industrial structure. Nuclear closure is a factor, not the only cause of industrial difficulty.

Are solar fields going bankrupt?

Individual developers and manufacturers can fail because of debt, power prices, grid congestion or Chinese competition. A bankrupt company does not mean the physical solar resource or the entire sector is uneconomic.

Solar additions globally remain much larger in capacity terms than new nuclear additions, while nuclear offers firmer output. A resilient system may need both, plus grids, storage, hydro, gas backup or demand management depending on geography.

Energy and wealth

Rich economies generally use large amounts of useful energy, and industrial growth requires reliable power. Yet wealth does not correlate only with raw generation. Efficiency, technology, institutions and the value produced per unit of energy matter.

The more defensible principle is that no advanced economy can sustain high living standards by making dependable energy scarce. Countries can reduce waste, but electrification and AI may increase total demand even as devices become more efficient.

Capacity is not generation

Comparisons must distinguish nameplate capacity from electricity actually produced. Solar and wind have variable capacity factors; nuclear plants typically generate a higher share of their rated output but require long outages for construction and maintenance. Cost comparisons also depend on financing, grid upgrades, backup and project risk. A serious national strategy measures the full system—reliability, emissions, land, time and capital—not a single technology’s cheapest headline number.

Reading a fast-moving story

Breaking reports often mix verified events, official claims, anonymous-source reporting and commentary. Those layers should not be treated as interchangeable. A government statement confirms what that government says; it does not independently prove attribution, intent or the full scale of an event. Images, documents and technical records can strengthen a claim, but each can also lack context. The most reliable assessment is therefore provisional and should be updated when named authorities, independent investigators or primary records provide new evidence.

What to watch next

Is China proving that nuclear power is indispensable to industrial wealth, or simply demonstrating that energy abundance requires multiple technologies rather than one ideological winner?
