Legislation known as the Thorium Energy Security Act, introduced in Congress last month by U.S. Sen. Tommy Tuberville (R., Ala.), would put a halt to the destruction of U.S. stockpiles of uranium-233 and instead would foster its integration into the development of thorium molten salt–cooled reactors, Newsweek reported last week. The act has been referred to the Senate Committee on Energy and Natural Resources.
