AOMORI (Kyodo) Japan Nuclear Fuel Ltd. is making arrangements to postpone by roughly two years the completion of a spent nuclear fuel reprocessing plant in the village of Rokkasho, Aomori Prefecture, due to a series of troubles during test operations, sources said Wednesday.

The plant, designed to extract uranium and plutonium from the nuclear fuel spent at power plants in the country, has been in the stage of what the operator calls the Final Commissioning Test and its construction is currently expected to be completed in October.
