Catalyzing a new nuclear energy ecosystem

Challenge

The world has not yet maximized nuclear energy’s potential to help meet the mounting demand for clean, firm, secure electricity.

Action

A partnership that seeks to enable the rapid expansion of safe and secure nuclear energy.

Results

A world where nuclear energy propels progress toward climate, energy security, and economic development goals without leading to more nuclear weapons.

The Nuclear Scaling Initiative (NSI) is a collaborative effort of NTI, Clean Air Task Force (CATF), and the EFI Foundation (EFIF) to build a new nuclear energy ecosystem that can quickly and economically scale to more than 50 gigawatts of safe and secure nuclear energy per year by the 2030s. The team’s plan for revolutionizing how nuclear energy is constructed, financed, and regulated will advance climate goals, spark economic development, expand energy access, and ensure that nuclear technology is used for only peaceful purposes.

Since 2023, NSI has combined CATF, EFIF, and NTI’s unparalleled capabilities in nuclear technology, policy, security, and finance, along with strong public and private sector experience and deep geopolitical insight. NSI is currently focused on driving progress in Central and Eastern Europe and the United States with an approach that emphasizes aggregated demand; multi-stakeholder risk-sharing; cohesive action by policymakers, the private sector, and civil society; accelerated deployment timelines; integrated supply chains; and strong nonproliferation and security practices. As the initiative progresses, NSI plans to broaden its scope to support the responsible expansion of nuclear energy in other regions, including Africa, the Middle East, South America, and Southeast Asia.
