Rokkasho Reprocessing Plant
Encyclopedia
The 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 undergoing test operations, separating a small amount of used nuclear fuel. It is the successor to a smaller reprocessing plant located in Tōkai, Ibaraki
.

In 2010, the Rokkasho Reprocessing Plant consisted of 38 buildings on an area of 3,800,000 m².

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 Jan. 27, 2008 in central Tokyo against the Rokkasho Reprocessing Plant. Over 810,000 signatures were collected and handed in to the government on Jan. 28, 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.

Vitrification
tests completed in November 2007. This consists of pouring high level dry waste reside along with molten glass into steel canisters.
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.
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 March 13 that 600 liters of water leaked at the Rokkasho spent fuel pool. According to The New York Times
, grid power was restored on March 14, 2011.
The 7 April aftershock caused the loss of grid power again until the next day.
Nuclear reprocessing
Nuclear reprocessing technology was developed to chemically separate and recover fissionable plutonium from irradiated nuclear fuel. Reprocessing serves multiple purposes, whose relative importance has changed over time. Originally reprocessing was used solely to extract plutonium for producing...
