The elimination of weapons-grade plutonium can be helped by blending it with uranium to make mixed-oxide fuel, writes William Shughart, a professor at Utah State University. However, the Department of Energy's MOX facility at the Savannah River site in South Carolina is in danger of having its budget cut, he writes. "There's a lot at stake. If the United States abandons the South Carolina project and fails to eliminate its surplus weapons-grade plutonium, Russia has said that it will stop converting plutonium into MOX. That, unfortunately, could expose Russia's plutonium stockpiles to the possibility of theft," Shughart writes.
