The first generation Uranium Enrichment Plant in Rokkasho, Aomori operated 1992 to 2010 with a capacity of up to 1,050 ton-SWU/year, which is equivalent to the nuclear fuel used by 8 or 9 reactors at 1,000 MW-class nuclear plants.

[1][2] A second generation plant using centrifuges with composite carbon-fibre rotors started operating in 2011.

The plant has a design reprocessing capacity of 800 tonnes-U/year, enough to reprocess the spent fuel produced by 30 reactors at 1,000 MW-class nuclear power stations, though full capacity has yet to be realized.

According to the current plan, Japanese electric power companies will be implementing Plutonium-Thermal utilization (MOX) with 16 to 18 of the nuclear reactors operating in Japan.

[4] JNFL also operates low and high level nuclear waste long-term storage facilities which will accommodate 2,880 canisters of vitrified high level waste and the ultimate capacity of the Low-Level Radioactive Waste Disposal Center now under construction will be 600,000 m3.
