First stage of Lanzhou centrifuge enrichment plant completed early
The third line of a centrifuge enrichment plant in China is finished, two years ahead of the date stipulated in the 1992 contract between Chinese and Russian nuclear industry, according to the Russian Ministry of Atomic Energy. The new plant is located about 25 km north of Lanzhou, in Gansu Province, and has a capacity of 500,000 SWU per year. The first and second stages of the plant, located in Hanjun, in the same province, were put into operation in March 1998 and April 2000 respectively. Furthermore, another 500,000 SWU per year is to be added subsequently at Lanzhou.

Expansion of India's military gas centrifuge uranium enrichment facility operational in 2015 - IHS
India is expanding a covert uranium enrichment plant that could potentially support the development of thermonuclear weapons, a defence research group said on Friday (June 20), raising the stakes in an arms race with China and Pakistan.
The revelation highlights a lack of nuclear safeguards on India under new Prime Minister Narendra Modi, while sanctions-bound Iran faces minute scrutiny in talks with world powers over its own nuclear programme.
New units at the Indian Rare Metals Plant would increase India's ability to produce weapons-grade uranium to twice the amount needed for its planned nuclear-powered submarine fleet, IHS Jane's said.
The facility, located near Mysore in southern India, could be operational by mid-2015, the research group said, basing its findings on analysis of satellite imagery and public statements by Indian officials.
(Reuters June 20, 2014)
India apparently finishes construction of military gas centrifuge uranium enrichment facility
India has expanded a secretive site that could be used to enrich more uranium for nuclear weapons, a US think tank said Wednesday (Dec. 4), citing satellite imagery.
The Institute for Science and International Security , a private group opposed to nuclear proliferation, said that India appeared to be finishing a second gas centrifuge facility at its Rare Materials Plant near the southern city of Mysore.
"This new facility could significantly increase India's ability to produce highly enriched uranium for military purposes, including more powerful nuclear weapons," the institute said in a report that analyzed an image taken in April.
The institute said that India started building a second centrifuge plant near Mysore in 2010, but it was unclear whether it was a replacement for the first facility at the site or a supplement.
If it is a new facility, "India could have more than doubled its enrichment capacity, if the original building continues to function as an enrichment plant," it said.
Indian officials have reportedly said that highly enriched uranium from Mysore would fuel its new nuclear-powered submarines. India's nuclear weapons program has traditionally been based on plutonium, not uranium. (The Frontier Post Dec. 4, 2013)

India expands military gas centrifuge uranium enrichment facility
The Rare Materials Plant (RMP), India's lone uranium enrichment plant, located at Rattehalli on the outskirts of Mysore, is undergoing massive capacity-building as part of India's gas centrifuge enrichment programme.
A new gas centrifuge plant is being built at the site to enhance the output of Highly Enriched Uranium (HEU), a fuel used in naval reactors and thermo-nuclear weapons, at least by three times the current production levels in next couple of years.
Sources in the RMP said the new centrifuge plant was coming up on an area of 120 acres and was nearing completion. By 2016, India looks to produce at least 30,000 separative work units (SWU) per year, a common measure of the output of a uranium enrichment plant, as India is going aggressively with its nuclear programme and plans to install more nuclear reactors in near future.
(Deccan Chronicle Sep. 3, 2012)
India appears to expand its military gas centrifuge uranium enrichment facility
Google Earth recently posted satellite imagery from GeoEye taken on March 3, 2010 of the Rare Materials Plant (RMP) in India. This is the site of India's military gas centrifuge uranium enrichment program. In the new imagery, initial excavation and construction of a large building or buildings can be seen. While the construction is in its early stages in this image, the size of the building or buildings to be constructed indicates that these will be large industrial buildings. A DigitalGlobe satellite image from 2005 shows the same area as undeveloped with several adjacent ponds.
Based on procurement data and public advertisements for bidding requests, Paul Brannan of Institute for Science and International Security (ISIS) concluded in 2006 that India was on the verge of adding at least 3,000 centrifuges to the RMP1. If the construction seen in the March 3, 2010 imagery is for a new gas centrifuge hall, India’s uranium enrichment capacity at RMP will be greatly expanded.
Since the 1970s, India has pursued gas centrifuges to enrich uranium. The history and current status of India’s gas centrifuge program has been a long-held state secret. ISIS has been producing reports that trace the history of India’s centrifuge enrichment program and assess its current and projected enrichment capacity based on open sources, information from interviews with Indian and other government officials, and publicly available procurement data.
The Indian Department of Atomic Energy (DAE) commissioned India's main enrichment plant, codenamed the Rare Materials Project (RMP), around 1990. In addition to a gas centrifuge facility, this site, located about 19 kilometers from Mysore, may also contain a uranium hexafluoride production facility. As per ISIS, by 1997, after several years of difficulty, India seems to have achieved a technical breakthrough at RMP. Although India has experienced difficulties in building centrifuges, it now appears to be competent at constructing centrifuges comparable to those common in Europe in the 1970s. ISIS concluded in 2007 that, India is currently operating between 2,000 and 3,000 centrifuges at the RMP. The DAE in 2007 was attempting to expand the number of centrifuges at RMP by 3,000, increasing RMP's capacity by at least 15,000 separative work units (SWU) per year, a common measure of the output of a uranium enrichment plant and more than double its current output.
The Indian government designated its gas centrifuge enrichment facilities, such as RMP, as military sites under the framework of US-India nuclear cooperation. Thus, India is unlikely to use these facilities to create fuel for the Tarapur boiling water reactors, which will be designated as civilian facilities. India is currently importing sufficient amounts of low enriched uranium (LEU) to fuel the Tarapur reactors. These reactors could have otherwise absorbed the RMP's capacity.
As a result of its recently acquired ability to import LEU, India can devote the enrichment capacity of RMP to highly enriched uranium (HEU) for military applications. As per ISIS in 2007, India would most likely use the HEU for fuel in submarine reactors and in thermonuclear weapons. The production of thermonuclear weapons may lead India to conduct additional underground nuclear tests as it seeks to make more deliverable, reliable, and efficient weapons.

India develops fourth generation uranium enrichment gas centrifuges
As part of India's strategic programme, the Bhabha Atomic Research Centre (BARC) has developed fourth generation uranium enrichment gas centrifuges with an output of more than 10 times the earlier design, a top BARC official has said.
"An experimental cascade of the fourth generation design is in operation at BARC and will soon be ready for induction at the Rare Materials Plant (RMP) in Ratnahalli near Mysore," BARC director Sreekumar Banerjee said.
"The Third generation design with 5 times more output than earlier designs are presently being inducted at RMP," he said.

Nuclear Fuel Complex (NFC)
Blast in Hyderabad Nuclear Fuel Complex
On Nov. 17, 2002, a blast occurred in the chemical plant used for uranium purification. The top lid of the process plant hit the asbestos sheet roof, which fell off. Seven persons were working in the plant at the time, but no one was injured. Uranium-bearing liquid contained in the plant spilled onto the ground and collected in a pit. It was later taken back into the process plant.
After the blast, the Health Physics Unit of the NFC monitored the area and declared there was no airborne activity and people were allowed to resume their work in the other plants at the NFC. (Rediff Nov. 18, 2002)
On April 22, 2003, the Atomic Energy Regulatory Board (AERB) permitted the resumption of operation of the wet section of Natural Uranium Oxide Fuel Plant (NUOFP) of the Nuclear Fuel Complex (NFC) in Hyderabad. The Board had suspended its operation on November 20, 2003, pending inquiry into the reasons of a chemical explosion.
A specialist investigation committee of the AERB confirmed that the explosion was due to what is known as "Red Oil Reaction" — uncontrolled chemical reaction involving hot organic liquid and aqueous nitrate solution. The committee observed that the necessary conditions such as presence of nitrate, organic liquids and temperature for causing the reaction existed in the evaporator at the wet section of the plant at the time of the incident. The NFC management has now modified the process to exclude the evaporation step. (The Hindu, April 23, 2003)

Iran announces tenfold increase in enriched uranium production in breach of nuclear deal
Iran has announced a tenfold increase in enriched uranium production as Tehran backs away from its nuclear deal with the west.
Ali Akbar Salehi, the head of Iran's atomic energy organisation, said enriched uranium production was now at 5kg per day, up from 450g two months ago.
The production increases were made possible by the introduction of two new advanced centrifuges, one of which is undergoing testing. Salehi said Iran was now operating 60 IR-6 advanced centrifuges, a violation of the deal.

Iran enriches uranium with advanced centrifuges not permitted by nuclear deal
Iran has committed another breach of its nuclear deal with major powers by enriching uranium with advanced centrifuges, a report by the U.N. nuclear watchdog policing that deal said on Thursday (Sep. 26), further fraying the landmark accord.
(Reuters Sep. 26, 2019)
Iran enriches uranium beyond nuclear deal assay limit
Iran has passed the 3.67% uranium enrichment cap set by its landmark 2015 nuclear deal and may enrich at even higher levels, the spokesman for Iran's Atomic Energy Organisation, Behrouz Kamalvandi, said on Monday (July 8) according to the IRIB news agency.
(Reuters July 8, 2019)
Iran amasses more low-enriched uranium than allowed by nuclear deal
Iran announced on Monday (July 1) it had amassed more low-enriched uranium than permitted under its 2015 deal with major powers, its first major step in violation of the deal since the United States pulled out of it more than a year ago.
The U.N. nuclear watchdog, the International Atomic Energy Agency (IAEA), which monitors Iran's nuclear program under the deal, confirmed in Vienna that Tehran had breached the limit.
(Reuters July 1, 2019)
Iran quadruples production of enriched uranium
Iran has quadrupled its production of enriched uranium amid tensions with the U.S. over Tehran's unraveling nuclear accord, two semi-official news agencies reported Monday (May 20), an announcement that came just after President Donald Trump and Iran's foreign minister traded threats and taunts.
While the reports said the production is of uranium enriched only to the 3.67% limit set by the 2015 nuclear deal that Tehran reached with world powers, it means that Iran soon will go beyond the stockpile limitations established by the accord.
(AP May 20, 2019)
Iran, world powers reach tentative agreement on Tehran's nuclear program
Iran and world powers reached a framework agreement on Thursday (April 2) on curbing Iran's nuclear program for at least a decade, a step towards a final pact that could end 12 years of brinkmanship, threats and confrontation.
The tentative agreement, after eight days of marathon talks in Switzerland, clears the way for negotiations on a settlement aimed at allaying Western fears that Iran was seeking to build an atomic bomb and in return lift economic sanctions on the Islamic Republic.
The framework is contingent on reaching an agreement by June 30. All sanctions on Iran remain in place until a final deal.
Under the outline deal, Iran would shut more than two-thirds of its installed centrifuges capable of producing uranium that could be used to build a bomb, dismantle a reactor that could produce plutonium, and accept intrusive verification.
Iran agreed to significantly reduce the number of installed uranium enrichment centrifuges it has to 6,104 from 19,000 and will only operate 5,060 for 10 years under the future agreement with the six powers, according to a U.S. fact sheet. Iran will only use first generation centrifuges during that time, it said.
One of the most sensitive issues during the negotiations, Iran's research and development work, will also be limited.
"Iran has agreed to not conduct research and development associated with uranium enrichment at Fordow for 15 years," the U.S. fact sheet said. It also noted that Iran will remove the 1,000 more advanced second-generation centrifuges currently installed at Natanz and place them in International Atomic Energy Agency-monitored storage for 10 years.

Iran has 18,000 centrifuges, including 1,000 new more efficient ones, ex nuclear chief says
Iran has installed 18,000 uranium-enrichment centrifuges, the country's outgoing nuclear chief was quoted as saying by Iranian media on Saturday (Aug. 17).
Iran has 17,000 older "first-generation" IR-1 centrifuges, of which 10,000 are operating and 7,000 are ready to start operations, the ISNA news agency quoted Fereydoun Abbasi-Davani, outgoing head of the Atomic Energy Organization of Iran (AEOI), as saying.
A May report from the U.N. nuclear watchdog indicated that Iran had by then installed roughly 16,600 IR-1 machines in two separate facilities.
Abbasi-Davani also said there were 1,000 new, more advanced centrifuges ready to start operations, in a reference to IR-2m centrifuges, which once operational would allow Iran to enrich uranium several times faster than the IR-1 machine.
The IAEA in its last report in May said Iran had installed a total of 689 such centrifuges and empty centrifuge casings.

IAEA resolution demands Iran suspend uranium enrichment
A 35-nation meeting of the U.N. atomic watchdog agency on Sep. 18, 2004, demanded that Iran suspend all aspects of uranium enrichment, setting an indirect November, 2004, deadline for Tehran to heed its conditions.
A resolution approved by the International Atomic Energy Agency's board of governors said it "considers it necessary" that Iran freeze all uranium enrichment and related programs.
It also said it "strongly urges" Iran to meet all demands by the agency in its investigation of the country's nearly two decades of clandestine nuclear activity, including unrestricted access to sites, information and personnel that can shed light on still unanswered questions on whether Tehran was interested in the atom for nuclear weapons.

Iran used Urenco centrifuge design
Iran has acknowledged to the U.N. its uranium enrichment centrifuge program is based on a European firm's designs that appear identical to ones used in Pakistan's quest for an atom bomb, diplomats say.
Tehran, accused by Washington of seeking to develop nuclear weapons, told the U.N. nuclear agency it got the blueprints from a "middleman" whose identity the agency had not determined, a Western diplomat told Reuters on condition of anonymity.
It was unclear where the "middleman" got the drawings. The U.N.'s International Atomic Energy Agency (IAEA) has said in a report Iran told the IAEA it got centrifuge drawings "from a foreign intermediary around 1987."
Several diplomats familiar with the IAEA said the blueprints were of a machine by the Dutch enrichment unit of the British-Dutch-German consortium Urenco.

On Aug. 8, 2005, Iran resumed uranium conversion at its facility near Isfahan under IAEA supervision, a move EU officials have warned will probably see its nuclear case sent to the U.N. Security Council for possible sanctions.
Iran had agreed to suspend all nuclear fuel work in November 2004 as part of a deal with the European Union while both sides explored a long-term arrangement for Iran's nuclear programme. But, on Aug. 6, 2005, Iran rejected an EU proposal offering it economic and political incentives to halt nuclear fuel work for good.

Iran to restart uranium enrichment at Fordo underground facility in breach of nuclear deal
Iran will start injecting uranium gas into centrifuges at its underground Fordow enrichment facility, Iranian President Hassan Rouhani said on Tuesday (Nov. 5), a highly symbolic breach that will complicate European efforts to salvage Tehran's nuclear deal.
Under the 2015 agreement between Iran and world powers, Iran agreed to turn Fordow into a "nuclear, physics and technology center"; where 1,044 centrifuges are used for purposes other than enrichment, such as producing stable isotopes, which have a variety of civil uses.

Iran ready to sharply increase enrichment work in Fordo underground facility - IAEA
Iran is ready to sharply expand its uranium enrichment in an underground site after installing all the centrifuges it was built for, a U.N. nuclear report showed on Friday (Nov. 16), a development likely to fuel Western alarm over Tehran's nuclear aims.
The Islamic state has put in place nearly 2,800 centrifuges that the Fordow enrichment site, buried deep inside a mountain, was designed for and could soon double the number of them operating to almost 1,400, according to the confidential International Atomic Energy Agency report obtained by Reuters.
Tehran has produced about 233 kg (512 pounds) of higher-grade enriched uranium since 2010, an increase of 43 kg since August this year, according to the report issued in Vienna.

Iran has boosted uranium enrichment capacity at Natanz:
Iran further increased its uranium enrichment capacity in the last three months, yet it also limited its progress in certain sensitive areas of its disputed nuclear program in an apparent attempt to avoid risking retaliation from Israel or the United States, according to a report issued Wednesday (May 22) by the United Nations nuclear watchdog agency.
The report by the International Atomic Energy Agency in Vienna said that since February Iran has added more than 520 advanced-design IR-2M centrifuges at its plant in Natanz. The model has up to five times the capacity of the first-generation centrifuges to enrich uranium.
The installations bring to about 700 the total number of the IR-2M centrifuges, toward Iran's goal of 3,132.

Japans sends some weapons-grade plutonium and highly enriched uranium to the U.S. for downblending
A ship thought to be carrying 331 kilograms of plutonium as well as highly enriched uranium kept by Japan is en route to the United States, where the material will be downgraded.
The vessel left a port in this prefecture northeast of Tokyo on March 22. The shipment, although not officially acknowledged by the Japanese government for security reasons, is part of a program to reduce Japan's stockpile of weapons-grade nuclear materials.
The transfer of research-purpose plutonium and highly-enriched uranium is based on a 2014 Japan-U.S. agreement to hand over the material to the United States. Japan's cooperation reflects U.S. efforts to reduce nuclear material that could be targeted by terrorists for their use.

Japan's MOX fuel imports cost up to nine times more than conventional uranium fuel
Five nuclear plant operators have spent at least ¥99.4 billion (US$ 836 million) on imports of plutonium-containing mixed oxide (MOX) fuel since it was first shipped to Japan in 1999, Jiji Press learned on Saturday (Feb. 21).
Some of the imports cost nine times more than conventional uranium fuel.
Japanese power companies that use or plan to use the MOX fuel commission the fuel's production from companies in France and elsewhere.
The five that imported MOX fuel are Tokyo Electric Power Co., Chubu Electric Power Co., Kansai Electric Power Co., Shikoku Electric Power Co. and Kyushu Electric Power Co., according to the Federation of Electric Power Companies of Japan.
Of the five, Kansai Electric, Shikoku Electric and Kyushu Electric have revised their monthly power rates to reflect the cost of using MOX fuel.
Since 1999, MOX fuel has been shipped to six of the five companies' nuclear power stations. Trade statistics compiled by the Finance Ministry and other data show that the imports since that time have totaled ¥99.437 billion (US$ 836 million), including the costs of transportation and insurance.
In June 2013, Kansai Electric imported 20 units of MOX fuel assemblies from France for ¥18.514 billion (US$ 156 million) for use at the No. 3 and No. 4 reactors at the Takahama power station in Fukui Prefecture.
The average cost per unit stood at ¥925 million (US$ 7.78 million), compared with the average of around ¥103 million (US$ 0.865 million) for 60 units of conventional uranium fuel that Kansai Electric imported from the United States between October and November that year, also for use at the two reactors.

Japan's plutonium stockpile increased to 47.1 tonnes in 2013
Japan possessed about 47.1 tons of plutonium in and outside the country as of the end of 2013, up some 2.9 tons from the year before, the Cabinet Office said Tuesday (Sep. 16).
Newly added were 2.3 tons generated through spent fuel reprocessing outsourced to Britain and 640 kg Japan had not reported to the global watchdog in 2012 and 2013. The 640 kg is part of mixed plutonium-uranium oxide (MOX) fuel stored in a reactor that was offline during this period.
Of the 47 tons of plutonium Japan owns, about 10.8 tons have been stored in the country and the remaining portion kept in Britain and France, where spent nuclear fuel from Japanese power plants has been reprocessed.

Japan's utilities fail to report plans for plutonium usage
The Federation of Electric Power Companies of Japan has violated government policy by failing to compile a plan on how it intends to use the half ton of plutonium it expects to extract from spent fuel in fiscal 2012, sources said Saturday (Apr. 21).
The deadline was March 31, when fiscal 2011 ended. Without a plan, Japan could come under international fire again for its blatant lack of transparency, given the risks of the plutonium being diverted for nuclear weapons use or terrorism.
In 2010, the federation said that by the end of March 2016, 5.5 to 6.5 tons of plutonium will be used each year at 16 to 18 of the reactors across Japan, but the viability of the project has been threatened by the Fukushima disaster.

Russia, Japan sign agreement on nuclear fuel supply
Russia and Japan signed an intergovernmental nuclear cooperation deal on Tuesday (May 12, 2009) during Prime Minister Vladimir Putin's visit to Tokyo.
The agreement opens the door for cooperation in the field of nuclear fuel cycle services and the construction of nuclear power plants.
Russia's nuclear chief said that the signing of the intergovernmental civilian nuclear power agreement would clear the way for Russia to supply low-enriched uranium to Japan worth hundreds of millions of U.S. dollars.

Japanese government releases first detailed English translation of plutonium holdings report
In response to a request from Citizens' Nuclear Information Center (CNIC) , for the first time the Japanese government has published a detailed English translation of its plutonium holdings report (as at 31 December 2006). The data includes input-output balance sheets.
The latest report includes data for the Rokkasho Reprocessing Plant for
the first time. Active testing using spent fuel began at Rokkasho on 31
March 2006 and the first plutonium-uranium mixed oxide product (MOX)
was produced on 16 November 2006.

Plutonium separated from Japanese spent fuel continues to be piled up
On 23 February 2007 the Federation of Electric Power Companies (FEPCO) published a compilation of Japan's electric power companies' "plutonium utilization plans" for the 2007 Fiscal Year (1 April 2007 - 31 March 2008).
Once again no indication is given of by when the plutonium separated at the Rokkasho reprocessing plant will be used up. The only conclusion that can be drawn is that the plutonium separated at Rokkasho will simply increase the size of Japan's already huge plutonium stockpile (43.1 tons at last count).

JNFL starts operating new centrifuges at Rokkasho-mura uranium enrichment plant
Japan Nuclear Fuel Ltd. started on Wednesday (Dec. 28) the operation of new, more efficient centrifuges at its uranium enrichment plant in Rokkasho, Aomori Prefecture.
After a warm-up operation, the centrifuges -- each capable of processing enrichment four to five times more efficiently than a previous one -- will start producing uranium products around March, the company said.
In one year of operation, the new centrifuges can enrich one-third of uranium required for a 1-gigawatt reactor per year, according to the operator.
Japan Nuclear Fuel plans to replace all old units with new ones over the next decade at the enrichment facility that went on-stream in 1992.

GNF-Japan Kurihama fuel fabrication plant obtains final approval for restart - without public involvement
Japan's Nuclear Regulation Authority (NRA) has approved the restart of Global Nuclear Fuel-Japan's (GNF-J's) fuel fabrication plant in Yokosuka in Kanagawa Prefecture. Last month the regulator concluded the facility meets revised safety standards.
GNF-J applied to the regulator in April 2014 for an assessment to confirm the Yokosuka plant meets revised safety standards, introduced in December 2013. GNF-J is part of the GE-led Global Nuclear Fuel joint venture with Hitachi and Toshiba, which designs and manufactures fuel for boiling water reactors.
On 8 March 2017, the NRA approved a draft review report confirming that GNF-J's uranium dioxide fuel fabrication facility is compatible with the new standards. The plant became the first fuel cycle facility to be confirmed as meet them.
The Ministry of Economy, Trade and Industry approved the restart of the facility on 29 March. At a meeting yesterday, the NRA commissioners gave the final approval needed for the plant to restart. Unlike with power reactors, the NRA said it was not necessary for GNF-J to seek approval from the Japan Atomic Energy Commission or the public to restart the facility.

Ulba Metallurgical Plant starts downblending of weapons-grade uranium
On October 8th, 2005, a U.S.-based nonproliferation group and Kazakh officials unveiled a project to eliminate about three tons of weapons-grade nuclear fuel which could be used to make some two dozen atomic bombs.
Under the project, about 6,400 pounds (2,900 kg) of nuclear fuel containing highly enriched uranium from a mothballed Soviet-built nuclear reactor in western Kazakhstan will be blended down at the Ulba Metallurgical Plant in Eastern Kazakhstan so that it cannot be used to make bombs. The uranium, less than 5 percent enriched, will be used for fuel for civilian reactors.
The $2 million project was initiated by the Nuclear Threat Initiative , a nonprofit organization dedicated to reducing the threat of nuclear, biological and chemical weapons. The U.S. group and the Kazakh nuclear industry shared the costs.

Uranium Enrichment and Fuel Fabrication: New Project Issues (Korea, DPR) · Decommissioning Issues (Korea, DPR)
North Korea has expanded its enriched uranium facility, U.N. nuclear inspector says:
North Korea has doubled the size of its facility for enriching uranium in recent years, according to the United Nations' top nuclear inspector, who voiced doubt that a diplomatic agreement can end leader Kim Jong Un's weapons programs.
In an interview with The Wall Street Journal on Monday (Mar. 20), Yukiya Amano, director general of the International Atomic Energy Agency, described North Korea as rapidly advancing its capacity to produce nuclear weapons on two fronts: the production of plutonium at its Yongbyon nuclear facility and the enrichment of uranium.

North Korea 'Has New Uranium Enrichment Facility':
North Korea built a new underground uranium enrichment facility in Tongchang, North Pyongan Province in 2006, separately from the existing one at Yongbyon in the same province, Liberty Forward Party lawmaker Park Sun-young claimed Wednesday (Oct. 19).
Park said she had the information from a North Korean Army lieutenant colonel she only identified as Lee (52), who she claimed supervised security when the regime built the new facility.
"Construction began in 2001 and was completed in 2006," Park said. "After a test run in 2007, it began extracting enriched uranium in 2009."
"The Yongbyon facility is an empty structure that was built in preparation for an international inspection, but the new facility in Tongchang is the real uranium enrichment facility," she said.

New North Korea enrichment facility could boost weapons fuel: report:
North Korea is operating a new nuclear facility that could double its known capacity to produce uranium-enriched fuel for nuclear weapons, a South Korean news report said on Wednesday (Nov. 5).
The move, if true, would be a further step in defiance of international pressure on Pyongyang to end its nuclear program in the form of layers of U.N. sanctions.
The new facility sits right next to a plant where in 2010 the North allowed a team of U.S. nuclear experts to tour what one described as a sophisticated and "industrial-scale" uranium enrichment facility.
"We've discovered the plant has recently been completed and is now in operation," South Korea's Joongang Ilbo newspaper, a mainstream daily, quoted a government official who handles intelligence on North Korea as saying.
Images taken by U.S. intelligence authorities with cameras mounted with heat sensors revealed telltale signs pointing to the operation of centrifuges inside the plant, the official was quoted as saying.

North Korea has secretly built a uranium enrichment plant:
North Korea has secretly and quickly built a new facility to enrich uranium, according to an American nuclear scientist, raising fears that the North is ramping up its nuclear program despite international pressure.
The scientist, Siegfried Hecker, said in a report posted Saturday (Nov. 20) that he was taken during a recent trip to the North's main Yongbyon atomic complex to a facility with a small industrial-scale uranium enrichment facility. The facility had 2,000 recently completed centrifuges, he said, and the North told him it was producing low-enriched uranium meant for a new reactor.
The facilities appeared to be primarily for civilian nuclear power, not for North Korea's nuclear arsenal, said Hecker, former director of the U.S. Los Alamos Nuclear Laboratory and a regular visitor to the North. He said he saw no evidence of plutonium production. But, he said, the facilities "could be readily converted to produce highly enriched uranium bomb fuel."
Uranium enrichment would give the North a second way to make atomic bombs, in addition to its known plutonium-based program.
