But the switch-over has some anti-nuclear groups worried. One reason is that the rods contain slightly more enriched uranium, up to 5 percent rather than the traditional 3 percent.
The newly designed rods are manufactured by Global Nuclear Fuel, or GNF, a joint venture of GE, Toshiba and Hitachi. Perry had been using rods manufactured by GE.
GNF claims the new design not only increases energy output but that its use ultimately will allow a reactor operator to use fuel rods with lower levels of enriched uranium and to use fewer of them.
