# The Download: Nuclear Power Reaches New Milestone, China Pursues Nvidia Alternatives
The United States hit a significant nuclear energy landmark this week as four reactors achieved record operational performance. This development comes as the nation pushes to expand nuclear capacity to meet rising electricity demand from data centers and AI infrastructure.
The milestone reflects broader momentum in nuclear energy. The sector has gained traction over the past two years as policymakers and tech companies recognize nuclear power's role in decarbonization and reliable baseload electricity generation. Data centers powering AI systems consume enormous amounts of electricity, and nuclear offers a carbon-free alternative to fossil fuels.
The timing matters. As power consumption from AI workloads accelerates, companies like Microsoft, Google, and Amazon have made commitments to nuclear partnerships. Some have signed power purchase agreements with existing reactors or invested in advanced reactor development. The four reactors reaching peak performance signals the existing fleet can contribute meaningfully to this demand.
Meanwhile, China is aggressively pursuing workarounds to US restrictions on advanced semiconductors. Reuters reports China is exploring ways to obtain Nvidia chips through alternative channels, even as American export controls tighten. The Biden administration has blocked high-end AI accelerators from reaching China, viewing them as national security risks tied to military applications.
China's efforts reflect the geopolitical reality of chip supply chains. Nvidia dominates the market for GPUs used in AI training and inference, making restrictions particularly effective. However, China is investing heavily in domestic chip design and exploring partnerships with manufacturers in allied nations. The strategy seeks to reduce dependence on American technology while maintaining AI research capacity.
These two stories underscore competing dynamics in tech infrastructure. The US is rebuilding domestic energy capacity to power AI systems while simultaneously restricting Chinese access to the hardware that drives AI advancement. Both moves aim to secure technological advantage. The nuclear milestone addresses one constraint. The export controls
