Iran says it is taking initial steps to design reactor fuel
Iran is taking preliminary steps to design uranium fuel with a purity of 20 percent for reactors instead of having to copy foreign designs, Iran's nuclear chief said on Sunday.
Iran's 2015 nuclear accord with world powers caps the level to which it is able to enrich uranium to 3.67 percent purity, well below the 20 percent it was reaching before the deal, and the roughly 90 percent that is weapons-grade.
