Changing Perceptions of Nuclear Energy

Over the past decade, the perception of nuclear energy has changed considerably. Governments, corporations, and environmental groups have started recognizing the critical role that nuclear power can play in decarbonizing the energy sector. This kind of carbon-free baseload resource is increasingly regarded as important for maintaining grid reliability while achieving net-zero emissions targets.

A Surge in Electricity Demand

After decades of flat demand growth, a surge in the electrification of transportation and industry, a sharp growth in the number of data centers, and the explosion of AI and machine learning applications have all contributed to a rapidly growing demand for power in the U.S. To meet that demand with decarbonization in play, substantial amounts of clean, firm-generating capacity will need to be added to the U.S. landscape. This is where SMRs and other advanced nuclear technologies come in.

SMRs and Advanced Reactors: Flexible Solutions for Diverse Applications

Nuclear technologies are being developed at various scales to meet different needs. Microreactors in the 1-20 MW output range are highly suitable for powering remote communities and industrial activities, whereas SMRs (up to 300 MW) are most suited for replacing retiring fossil fuel plants. Meanwhile, international interest in gigawatt-scale reactors continues to be strong.

Advanced reactor designs offer new capabilities, including load following to complement renewables and direct process heat for industrial applications. Extensive use cases are being explored to help decarbonize different sectors of the economy.

Policies to Support Nuclear Growth

Policymakers will need to design supportive policies and regulations that help realize nuclear's potential for fully decarbonizing the economy. The list includes sharing the early-of-a-kind costs of new reactor projects, gaining access to federal support that would allow for U.S. nuclear exports, and subsidizing the existing nuclear fleet through production tax credits and other programs. Continued and enhanced policies will be essential in reaching these decarbonization goals.
