Uranium Supply is Not a Significant Constraint to Using Nuclear Energy for Climate Mitigation

Nuclear energy is the largest source of carbon-free power in the United States and second largest source globally. As countries around the world consider nuclear energy for their 21st century decarbonization needs, one important question is whether there is enough uranium fuel for nuclear energy to play a greatly expanded role in global energy supply.

Deep Decarbonization Models Miss the Mark on Advanced Nuclear Energy

In the past three years, nine U.S. states enacted legislation to fully decarbonize the electricity sector by 2050 or sooner.[1] Three of those state laws require 85-100 percent reductions in economy-wide greenhouse gas emissions. At least 29 U.S. electric and gas utilities have pledged to reduce CO2 or GHG emissions by similar amounts.[2] Earlier this year, President Biden proposed a target of 100 percent clean electricity by 2035.

Advanced Nuclear Energy is Critical Energy Infrastructure

Just as existing nuclear power plants provide the bedrock for our modern clean energy infrastructure, developing the infrastructure to commercialize advanced nuclear technologies will allow the United States to finish the task of decarbonization while providing high-paying jobs. Advanced nuclear energy is critical infrastructure. U.S. investment in developing new reactor technologies is needed to unlock economic, environmental, social, and national security benefits for the United States and the world in the 21st century.

Advanced Reactors in the Energy Act of 2020 and the New Administration

The Energy Act of 2020, passed in December 2020 as part of the Omnibus, is the most sweeping piece of energy legislation enacted in more than a decade. Built on years of work by Congressional leaders, staff, and stakeholders, the Act combines multiple bills across the energy sector.

We Need Both Nuclear and Renewables to Protect the Climate

The balance of peer-reviewed literature, international energy organizations, and national energy policies are unequivocal: nuclear is a carbon-free energy source with an important role to play in decarbonizing the global economy.
