U.S. Should Begin Laying the Foundation for New and Advanced Nuclear Reactors: Report
New and advanced types of nuclear reactors could play an important role in helping the U.S. meet its long-term climate goals, but a range of technical, regulatory, economic, and societal challenges must first be overcome.

Enhancing Advanced Nuclear Reactor Analysis
Nuclear power is a significant source of steady carbon-neutral electricity, and advanced reactors can add more of it to the U.S. grid, which is vital for the environment and economy. Sandia Lab researchers have developed a standardized screening method to determine the most important radioactive isotopes that could leave an advanced reactor site in the unlikely event of an accident.

Shutting Down Nuclear Power Could Increase Air Pollution
Nearly 20 percent of today’s electricity in the United States comes from nuclear power. The U.S. has the largest nuclear fleet in the world, with 92 reactors scattered around the country. Many of these power plants have run for more than half a century and are approaching the end of their expected lifetimes. If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate.

The Cold War Legacy Lurking in U.S. Groundwater
In America’s rush to build the nuclear arsenal that won the Cold War, safety was sacrificed for speed. ProPublica has cataloged cleanup efforts at the 50-plus sites where uranium was processed to fuel the nation’s nuclear arsenal. Even after regulators say cleanup is complete, polluted water and sickness are often left behind.
