Major technology companies are moving beyond renewable energy pledges and directly investing in nuclear infrastructure to power their data centers. Google has partnered with Georgia Power to uprate existing reactors, while Samsung committed up to $100 million to support Kairos Power's advanced reactor demonstration project. These aren't theoretical commitments; they represent concrete capital flowing into nuclear technology at a scale rarely seen outside government funding.

Why Are Tech Companies Suddenly Investing in Nuclear Power?

The shift reflects a fundamental recognition: data centers running artificial intelligence systems require massive, continuous electricity supplies that renewable energy alone cannot reliably provide. Unlike solar and wind, which generate power intermittently, nuclear plants operate 24/7, making them the only carbon-free option for baseload power that AI infrastructure demands.

Samsung's decision to join Kairos Power's engineering and construction team for the Hermes 2 demonstration plant exemplifies this commitment. The South Korean conglomerate is providing not just capital but direct engineering expertise, signaling confidence that advanced reactor designs will be commercially viable within the next few years. This partnership will support both the Hermes 2 project and future deployments of Kairos's technology across multiple sites.

What Nuclear Projects Are Moving Forward Right Now?

Beyond private sector partnerships, the nuclear industry is experiencing accelerated progress across multiple fronts. Google and Georgia Power entered into an agreement where Google will provide support to uprate the Vogtle and Hatch nuclear power plants, adding approximately 96 megawatts of new capacity to the grid. The Vogtle uprate was already approved by the Georgia Public Service Commission in 2025, while the Hatch uprate still requires regulatory approval.

Internationally, momentum is building rapidly. Poland is advancing its first nuclear power plant through a partnership between Polskie Elektrownie Jądrowe and a Bechtel-Westinghouse consortium, with partners developing a memorandum of understanding for potential deployment of GE Vernova Hitachi's BWRX-300 reactor in Europe and the United Kingdom. Italy's Senate passed legislation allowing the government to establish a framework for bringing nuclear power back to the country, marking a significant policy reversal after decades of nuclear abandonment.

How Are Researchers Improving Nuclear Reliability?

Innovation is also accelerating on the technical side. Researchers at Argonne National Laboratory have designed a compact matrix-type heat exchanger for molten salt reactors, featuring an embedded hardware-software system with machine learning-based monitoring. Molten salt reactors must be continuously monitored for blockages caused by fluid freezing, which can result from impurity accumulation or inadequate insulation. These blockages can slow operations and require urgent attention, making automated monitoring critical for reliability.

By embedding artificial intelligence into the monitoring system, operators can detect problems earlier and reduce costly interruptions. This represents a broader trend where AI is being integrated into nuclear operations not to replace human expertise but to enhance safety and efficiency.

Steps to Tracking Nuclear Industry Developments

• Monitor Corporate Partnerships: When major tech companies sign binding agreements with nuclear developers, it signals genuine long-term commitment. Track announcements from companies like Google, Samsung, and Microsoft about nuclear infrastructure investments, as these often precede broader industry shifts.
• Watch Regulatory Approvals: Nuclear projects require multiple layers of government approval. Follow filings with agencies like the Georgia Public Service Commission and international regulatory bodies to understand which projects are moving from planning to construction phases.
• Follow International Policy Changes: Countries like Italy and Poland are updating nuclear policies after years of opposition or inaction. These policy reversals often indicate shifting energy priorities and can accelerate deployment timelines for new reactor technologies.
• Track Technology Demonstrations: Projects like Kairos Power's Hermes 2 are critical milestones. When demonstration plants move from planning to construction, it typically means commercial deployment is 3 to 5 years away.

The convergence of AI growth and nuclear innovation is reshaping workforce development and supply chains across the industry. Companies are preparing for significant expansion by training new workers and establishing partnerships with construction firms and engineering companies capable of scaling production of reactor components.

What distinguishes this nuclear revival from previous cycles is the specificity and urgency of the demand signal. Rather than waiting for government mandates or carbon pricing to make nuclear economically attractive, private companies are actively committing capital because they face genuine constraints in meeting their power requirements while maintaining carbon-neutral operations. This creates a self-reinforcing cycle where investment accelerates technology development, manufacturing costs decline through scale, and deployment accelerates further.

The geopolitical implications are significant. As AI infrastructure becomes increasingly dependent on reliable, carbon-free power, energy security becomes intertwined with technological leadership. Countries and regions that can deploy small modular reactors and upgrade existing nuclear capacity quickly will have competitive advantages in hosting AI data centers and attracting technology investment. This urgency is driving nuclear development programs across Europe, North America, and Asia.
