Rokkasho Reprocessing Plant
The Rokkasho Reprocessing Plant (六ヶ所村核燃料再処理施設 Rokkasho Kakunenryō Saishori Shisetsu ) is a nuclear reprocessing plant with an annual capacity of 800 tons of uranium or 8 tons of plutonium, owned by Japan Nuclear Fuel Limited located in the village of Rokkasho in northeast Aomori Prefecture, Japan approximately 17 miles (27 kilometers) north of the US Air Force's Misawa Air Base. Since 1993 there has been US$ 20 billion invested in the project, nearly triple the original cost estimate. It is currently[when?] undergoing test operations, separating a small amount of used nuclear fuel. It is the successor to a smaller reprocessing plant located in Tōkai, Ibaraki.
At the same site there will also be:
- A high level nuclear waste monitoring facility
- A MOX fuel fabrication plant
- A uranium enrichment plant
- A low level radioactive waste landfill
In 2010, the Rokkasho Reprocessing Plant consisted of 38 buildings on an area of 3,800,000 m². 
In May 2006, an international awareness campaign about the dangers of the Rokkasho reprocessing plant, Stop Rokkasho, was launched by musician Ryuichi Sakamoto. Greenpeace has opposed the Rokkasho Reprocessing Plant under a campaign called "Wings of Peace – No more Hiroshima Nagasaki", since 2002 and has launched a cyberaction to stop the project. Consumers Union of Japan together with 596 organisations and groups participated in a parade on 27 January 2008 in central Tokyo against the Rokkasho Reprocessing Plant. Over 810,000 signatures were collected and handed in to the government on 28 January 2008. Representatives of the protesters, which include fishery associations, consumer cooperatives and surfer groups, handed the petition to the Cabinet Office and the Ministry of Economy, Trade and Industry.
Seven consumer organisations have joined in this effort: Consumers Union of Japan, Seikatsu Club Consumer's Co-operative Union, Daichi-o-Mamoru Kai, Green Consumer's Co-operative Union, Consumer's Co-operative Union "Kirari", Consumer's Co-operative Miyagi and Pal-system Co-operative Union.
In June 2008, several scientists stated that the Rokkasho plant is sited directly above an active geological fault line that could produce a magnitude 8 earthquake. But Japan Nuclear Fuel Limited have stated that there was no reason to fear an earthquake of more than magnitude 6.5 at the site, and that the plant could withstand a 6.9 quake.
 2011 Tōhoku earthquake and tsunami
After the Tōhoku earthquake in March 2011, the plant ran on emergency power provided by backup diesel generators. The emergency generators were not intended for long-term use. Reportedly there are about 3,000 tons of highly radioactive used nuclear fuel stored in Rokkasho at current, that could overheat and catch fire if the cooling systems fail. Japanese radio reported on 13 March that 600 liters of water leaked at the Rokkasho spent fuel pool. According to The New York Times, grid power was restored on 14 March 2011.
