"HEU is not needed for the vast majority of civilian purposes and most reactors using HEU should be converted to operate on lowenriched fuel that cannot be used in nuclear weapons or shut down so that terrorists cannot get their hands on it. With Barack Obama and Joe Biden's leadership, the U.S. will lead the effort to remove HEU from vulnerable research reactor sites around the world, assist in the conversion process, give unneeded facilities incentives to shut down, enhance physical protection measures pending HEU removal, and blend down recovered civil HEU for use as power reactor fuel."
