China has become one of the top players on the global stage for nuclear power generation, possessing an advanced nuclear power industry chain including uranium resources exploration, nuclear fuel supply, engineering design and development, engineering supervision, equipment manufacturing, operational maintenance and disposal of radioactive waste.
China National Uranium Co, a mining branch of CNNC, reported a 28.5 percent year-on-year rise in first-quarter revenue, with profits up 7.54 percent.
Mining giant Rio Tinto will sell its entire 68.62 percent stake in Rossing Uranium Ltd in Namibia for $106.5 million to China National Uranium Corporation Ltd, in order to focus on its core assets including iron, copper and aluminum, the company said on Monday.
"Zhu Yi, a Hong Kong-based analyst at Bloomberg Intelligence, said the cooperation could help the Chinese company's overseas expansion, as the sale offers CNUC access to the market of the Rossing mine in Namibia, which has the world's longest-running open pit uranium mine.
Being the world's longest-running open pit uranium mine, the Rossing business has produced the most uranium of any single mine since it became operational in 1976, exporting uranium oxide from Namibia to nuclear power utilities around the world.
The Rossing mine produced 2,110 metric tons last year and Rio Tinto's share of its mined uranium was 1,448 tons.
Industry insiders believe China's demand for uranium resources for nuclear power generators will increase in the mid to long term, to meet the rise of nuclear development in the country.
Namibia is the fourth-largest producer of uranium in the world after Kazakhstan, Canada and Australia.
The contingent payment is linked to uranium spot prices and Rossing's net income during the next seven calendar years, said Rio Tinto.
Subsidiary to ramp up throughput to ensure uranium facility reaches its designed capacityThe uranium subsidiary of China General Nuclear Power Corp, the country's largest nuclear operator, has said the company's Husab Uranium Mine located in Namibia will continue to be optimized this year.
The Namibian Husab Uranium Mine, the third-largest uranium mine in the world and China's largest investment project in Africa, has been constantly increasing output since it came online in late 2016.
Taurus Mineral Ltd, an entity owned by a subsidiary of CGN called Uranium Resources Co Ltd and the China-Africa Development Fund, holds a 90 percent share in the mine and the Namibian state-owned mining company Epangelo has 10 percent.
Uranium is considered to be one of six mineral resources of strategic importance by the Namibian government.
The country has two significant uranium mines capable of providing 10 percent of the world's output, according to the world nuclear association.
Industry insiders believe Chinese-African cooperation on uranium resources is a win-win solution and it is also strategically important for China to secure fuel resources, given its ambitious nuclear power generation expansion plans.
Joseph Jacobelli, a senior analyst of Asian utilities and infrastructure at Bloomberg Intelligence in Hong Kong, said China's demand for uranium resources for nuclear power generators will increase in the mid to long term, considering the sharp rise in the number of nuclear reactors in the country.
Contracts have been signed for nuclear projects in Argentina while the CNNC and its Saudi Arabian partner have agreed to push forward cooperation on uranium and thorium resources.
In Ghana, the CNNC has helped convert a local highly-enriched uranium nuclear reactor into a low-enriched one.
The Namibian Husab Uranium Mine operated by China's State-owned China General Nuclear Power Corp had produced over 1,000 metric tons of uranium oxide in 2017.
The Husab mine, the third-largest uranium mine, will continue to be optimized in 2018.
The company said the mine will produce 6,500 tons of uranium oxide within a few years.
The mine's optimization is part of CGN's efforts to expand its uranium supply chain for domestic and worldwide civil projects; it has put together agreements in most of the world's uranium-producing countries, including Namibia, Kazakhstan, Australia and Canada.
"China's nuclear power generators' need for uranium resources will rise exponentially in the mid to long term, given the sharp rise in nuclear reactors in the nation," he said.
"The mine produced the first drum of uranium oxide on Dec 30, 2016.
CGN announced last May that it would increase its nuclear fuel supply, including uranium mining, nuclear fuel pellets and nuclear fuel fabrication, catering to rising demand for its civil power plant projects.
Rio Tinto's metals and materials, including aluminium, copper, diamonds, gold, industrial minerals, iron ore, coal and uranium, essentially make up the world around us.
The traveling-wave reactor is a new nuclear design that uses fourth generation technology, which will reduce the need for the enrichment and reprocessing of uranium.
TWR, a new nuclear design using fourth-generation technology, could reduce the need for the enrichment and reprocessing of uranium.
China National Nuclear Corp, one of the country's largest nuclear companies, signed a memorandum of understanding with Saudi Arabia last week to further explore and assess uranium and thorium resources in the country.
Yu Zhiping, general manager of CGNPC Uranium Resources Co Ltd, confirmed that the company has been looking to increase its supply of domestic deposits known as "yellowcake".
"China has substantial deposits of uranium, which is widespread," Yu said"In the past two decades, we have explored several sandstone uranium deposits in northern China's basins," he added about CGNPC, which is a subsidiary of China General Nuclear Power Corp. "We plan to boost domestic uranium supplies and ensure energy sources for developing nuclear power.
"In 2008, China discovered its first 10,000-metric-ton level leaching sandstone uranium deposit in the Yili basin in the northwestern Xinjiang Uygur autonomous region.
Four years later, another large leaching sandstone uranium deposit was discovered in the Daying area of the northern Inner Mongolia autonomous region.
The Yili basin, which has large uranium deposits, will be turned into a production base, according to Yu.
There is also substantial potential for uranium deposits in the Erdos Basin and the Songliao Basin in Northeast China.
"As a country, we are not lacking in uranium resources," Yu, at CGNPC, said.
"Low prices in the past five years have seen China stockpile uranium reserves.
Li Ning, dean of the School of Energy Research under Xiamen University, felt it made sense for the world's second largest economy to import more uranium.
JIANG KEHONG / XINHUAOverseas operations are crucial to the uranium subsidiary of China General Nuclear Power Corp.
The State-owned energy giant has a particularly close relationship with Kazakhstan through CGNPC Uranium Resources Co Ltd. Key agreements cover uranium mining, nuclear fuel pellets and nuclear fuel fabrication.
CGN has secured 40,000 metric tons of uranium from the transcontinental country in northern Central Asia and East Europe.
About 16,000 tons of uranium had been imported from Kazatomprom, Kazakhstan's state-owned nuclear company, by the end of this May, according to He.
The company was set up to develop the Irkol and Semizbai uranium deposits.
The two mines have an annual capacity of 1,200 tons of uranium, Li pointed out.
Kazakhstan has been an important source of uranium for more than 50 years with a steady output and high quality yield.
Kalmukambetov Aidos, director of Semizbay's mining operation, singled out CGN's capital investment and advanced technology for helping the site produce 500 tons of uranium a year.
CGN's Semizbay operation is the first Chinese overseas uranium mining project.
"It has not only secured CGN's uranium supply abroad, but also helped the company gain experience in the operation and management of uranium mines overseas," said Joseph Jacobelli, a senior analyst of Asian utilities and infrastructure at Bloomberg Intelligence.
LUKE MACGREGOR / BLOOMBERGCGN is becoming a major player on the global stage after expanding its civil uranium supply chain to meet increased domestic demandChina's largest nuclear power group is expanding its uranium supply chain for domestic and worldwide civil projects.
This has been part of the company's development in the past 11 years, Yu Zhiping, general manager of CGNPC Uranium Resources Co Ltd, a subsidiary of CGN, stressed.
"It is extremely important for Chinese nuclear power operators to secure uranium resources overseas for long-term supply security," said Joseph Jacobelli, a senior analyst of Asian utilities and infrastructure at Bloomberg Intelligence in Hong Kong.
Back in May, CGN announced that it would increase its nuclear fuel supply, including uranium mining, nuclear fuel pellets and nuclear fuel fabrication, to cater for rising demand for its civil power plant projects.
"Besides its close business ties in Kazakhstan, CGN owns and operates the Namibian Husab Uranium Mine, which can produce 5,500 metric tons of nuclear fuel per year.
It is the third largest uranium mine in the world.
Last year, the company also paid $63.78 million for 19.99 percent stake in Fission Uranium Corp in Canada.
It was the first direct investment by a Chinese group in the Canadian uranium sector.
Along with Australia, Kazakhstan and Canada account for 63 percent of the world's uranium resources, figures released by the International Atomic Energy Agency showed.
Still, there are few countries expanding their civil nuclear power sector, so uranium supplies should not be problem, Jacobelli pointed out.
Although the price of uranium is expected to climb in the long term, CGN is considering acquiring more assets to cope with demand.
The uranium subsidiary of China General Nuclear Power Corp, the country's largest nuclear operator, is looking to expand nuclear fuel supply deals with Kazakhstan, including uranium exploration, trade, nuclear fuel pellets and component processing.
中国最大的核电运营商——中国广核集团下属的铀业子公司，正寻求与哈萨克斯坦扩大核燃料供应合作，包括铀矿勘探、贸易、核燃料芯块以及组件加工等领域。
According to Yu Zhiping, general manager of the company's uranium subsidiary CGN Uranium Resources Co Ltd, the nuclear fuel fabrication plant in Kazakhstan, a joint venture between KazAtomProm and CGN, is under construction and on schedule, and is expected to be operational by 2019.
据中广核铀业发展有限公司总经理于志平介绍，由哈萨克斯坦国家原子能公司（KazAtomProm）与中广核共同投资建设的位于哈萨克斯坦的核燃料制造厂正在按计划施工建设中，预计将于2019年投入运营。
"The fuel will also be supplied to Kazakhstan's planned nuclear plant, and in the expansion of cooperation with Kazakhstan in both uranium production and fuel assembly.
该燃料也将供应给哈萨克斯坦计划建设的核电站，并且在铀生产和燃料组件方面扩大与哈萨克斯坦的合作。
"Being the first uranium mining project invested overseas, the Semizbay mine project in Kazakhstan has not only helped secure CGN's uranium assets abroad, but also helped the company gain experience in the operation and management of uranium overseas, said Yu.
“作为首个海外铀矿投资项目，哈萨克斯坦谢米兹拜伊铀矿项目不仅有助于保障中广核在海外的铀资源资产，同时也使公司在海外铀矿运营管理和经验积累方面获益良多。”
Kazakhstan is the world's leading uranium producer, accounting for 39 percent of output in 2015, and KazAtomProm has said it aims to supply up to one-third of the world fuel fabrication market by 2030.
2015年，哈萨克斯坦是全球最大的铀生产国，产量占全球的39%，而哈萨克原子能公司（KazAtomProm）表示其目标是在2030年前为全球燃料制造市场供应高达三分之一的份额。
CGN has been seeking more uranium resources globally, and has secured uranium projects in countries such as Namibia, Kazakhstan and Australia.
CGN一直在全球范围内积极寻求更多的铀资源，并已在纳米比亚、哈萨克斯坦和澳大利亚等国家确保了铀矿项目。
Last year, CGN paid $63.78 million for a nearly 20 percent stake in Canada's Fission Uranium Corp. A report on China's power utilities M&A trends, by Bloomberg Intelligence by Joseph Jacobelli and Charles Shum, revealed that domestic and overseas M&As by Chinese electric power utilities are expected to accelerate in the next few quarters thanks to financial strength and policy support.
去年，中国广核集团斥资6378万美元收购了加拿大Fission铀业公司近20%的股份。一份由彭博智能（Bloomberg Intelligence）的约瑟夫·雅各布利（Joseph Jacobelli）和查尔斯·舒姆（Charles Shum）发布的报告揭示，得益于强大的财务实力和政策支持，中国电力公用事业公司在国内外的并购活动预计在未来几个季度将会加速增长。
CGN, China's leading listed power developer by market value, has also been focusing on uranium assets in Australia, it said.
中国市值领先的上市电力开发商——中国广核集团（CGN）也表示，他们一直在关注并聚焦于在澳大利亚的铀资产。
"This was followed by uranium which accounted for 12.8 percent of total exports destined mostly to China," he added.
Xin Feng, chairman of China Nuclear Energy Industry Corp, who is also a member of the 14th National Committee of the Chinese People's Political Consultative Conference, said the government should also step up efforts in geological work related to uranium, the primary fuel for nuclear reactors, to ensure sufficient steady development of nuclear power in the country.
China should improve domestic exploration and development of uranium resources and resource reserves as soon as possible, while making efforts to increase financial support for domestic uranium exploration and boost investment in basic geological work related to uranium ore, he said.
It has an advanced nuclear power industry chain including uranium resources exploration, nuclear fuel supply, engineering design and development, engineering supervision, equipment manufacturing, operational maintenance and disposal of radioactive waste.
它拥有包括铀资源勘查、核燃料供应、工程设计与开发、工程监理、设备制造、运行维护和放射性废物处置在内的先进核电产业链。
Proponents of this slightly radioactive element say it is clean, green and safer than uranium.
"In the early days of nuclear energy, thorium was thought to be a lot more abundant than uranium.
The concern was that there was not enough uranium to support large-scale energy production, so thorium was considered as a long-term alternative.
"When the US dropped thorium research, uranium was no longer in short supply and the thorium research had hit technical obstacles.
"The point is, thorium reactors are still being developed and are not commercially viable compared to uranium reactors.
The waste from thorium reactors breaks down faster than the waste from uranium reactors.
It is more abundant than uranium and is fertile rather than fissile, meaning it can be converted into fissile material through radiation.
It is meant to be used alongside fissile materials such as recycled plutonium and uranium.
Oak Ridge National Laboratory in Tennessee, United States, built such a reactor in the 1960s, but it was shelved by the administration of president Richard Nixon due to technical problems and because there was no longer an urgent need for an alternative to uranium.
The International Atomic Energy Agency said work on the use of thorium as a fuel for nuclear power began at about the same time that the first studies on uranium and plutonium started.
"In spite of a rather long list of advantages, thorium is not yet augmenting the use of uranium fuel on a commercial basis, although research efforts regarding the thorium fuel cycle continue," the report said.
"As yet, there is no commercial fabrication or reprocessing infrastructure for thorium fuel, unlike the available infrastructure for the uranium fuel cycle.
Only some 20 percent of the 2,300 graduates hired by CNNC in 2016 majored in nuclear-related courses as very few nuclear-related fields like nuclear fusion, uranium enrichment and post-processing differ widely from each other, said Wan.
