New “fast reactors” promise sustainable nuclear energy. They also pose serious proliferation risks because they can make lots of plutonium.
The Energy Department’s choice for the leading reactor design for reviving nuclear power construction in the United States is so at odds with U.S. nonproliferation policy that it opens America to charges of rank hypocrisy. The Biden administration is proposing to use nuclear fuels that we are telling others—most immediately Iran—not to produce. It will make it difficult to gain the restraints the United States seeks to limit nations’ access to bomb-grade uranium and plutonium.
