Rokkasho Reprocessing Plant
Capacity
800tHM/yr
Rokkasho Reprocessing Plant is a reprocessing facility operated by Japan Nuclear Fuel Limited in Japan. It has a capacity of 800 tHM/yr as of 2022, about 21% of world reprocessing capacity.
Under construction since 1993, with completion postponed more than twenty times. Japan's closed-cycle policy, and the plutonium balance that policy depends on, rests on a plant that has never operated commercially.
