Global nuclear energy surge accelerates with new reactors and tech breakthroughs

The nuclear energy sector has seen a series of key developments in recent weeks. Major announcements came during the World Nuclear Symposium 50, with advances in reactor technology and international collaboration taking centre stage. Countries and companies are pushing forward with new projects to expand nuclear capacity and innovation. China has given the green light for ten new nuclear reactors, marking a significant expansion of its energy infrastructure. The move aims to boost clean energy production and reduce reliance on fossil fuels.

In the United States, the Department of Energy (DOE) has revealed the first selections for its pilot reactor programme. The initiative supports the development of next-generation nuclear technology, though specific details on the chosen projects remain limited. Meanwhile, Deep Atomic has unveiled plans for a Small Modular Reactor (SMR) designed specifically for data centres. The company is working on underground 15 MW SMRs in Berkeley, USA, with potential applications for AI data centres. However, no firm timelines or locations for deployment have been confirmed. International cooperation is also advancing, as Framatome prepares to share its expertise in fast reactors with Japan. The partnership will focus on improving reactor efficiency and safety, building on decades of experience in the field.

The latest announcements highlight a growing momentum in nuclear energy development. China's reactor approvals, the DOE's pilot programme, and Deep Atomic's SMR plans all point to a push for cleaner and more efficient power solutions. Collaborations like the one between Framatome and Japan further strengthen global efforts to advance nuclear technology.
