A new generation of so-called “advanced” nuclear power reactors that Washington believes could help fight climate change often present greater proliferation risks than conventional nuclear power, a science advocacy group said on Thursday. President Joe Biden, a Democrat, has made curbing climate change a priority and has supported research and development for advanced nuclear technologies. The reactors are also popular with many Republicans. Last October, the month before Biden was elected, the U.S. Department of Energy, awarded $80 million each to TerraPower LLC and X-energy to build reactors it said would be operational in seven years. Advanced reactors are generally far smaller than conventional reactors and are cooled with materials such as molten salt instead of with water. Backers say they are safer and some can use nuclear waste as fuel. “The technologies are certainly different from current reactors, but it is not at all clear they are better,” said Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists.
