China's ambitions to lead the world in nuclear power were boosted today by reports that its scientists had mastered a key technique in the reprocessing of spent uranium.

State media claimed the technology overcame a supply bottleneck and ensured China would have sufficient nuclear fuel for at least 3,000 years.

The breakthrough would be a boon to the domestic industry, which is in the early stages of what looks likely to be the most spectacular burst of reactor-building in world history.

Due to surging demand for energy and growing concerns about pollution, China's nuclear-power generating capacity is projected to increase up to tenfold in the next 10 years. By 2030 China could be on course to overtake the US as the world's leading atomic energy producer.

The technology, developed and tested at the number 404 factory of the China National Nuclear Corporation, situated in the Gobi desert, enables recycling of irradiated fuel, according to China Central Television. How this differs from existing reprocessing methods in other countries is unclear, but the state broadcaster said that with this technique a kilo of uranium could produce close to 60 times more power than was now possible in China.

If proven this method would extend the "usage life" of the 171,400 tonnes of the country's known uranium deposits, which previously were forecast to last less than 70 years.

Reprocessing can also provide fissile material for weapons, though details have not yet been disclosed about the potential impact on China's nuclear arsenal.

China first tested an atomic bomb in 1964, but it was slow to adopt nuclear power because of the cheapness and abundance of domestic coal, and the government was reluctant to depend on expensive foreign technology and uranium imports. But in recent years growing wealth and shifting environmental priorities have prompted a change.

According to the International Atomic Energy Agency, China now has 13 operating reactors and 26 more facilities under construction.

China National Nuclear Corporation said last year it planned to invest 800bn yuan (£78bn) in the industry by 2020. China has already been replicating the technology of its foreign suppliers and is moving to design its own reactors and reprocessing plants. The next step is construction and overseas sales.

I would take this with a pinch of salt. What exact technology are they talking about? Reprocessing is a huge area of development and a fundamental breakthrough is extremely unlikely by the chinese atleast. France and Japan have the necessary knowhow and research infrastructure in place to attain any such breakthrough.

Well, here's how I think of it: There's not even "fake news" about Indian existing breakthroughs, only news about India's plans which always fade away after a few years. Even if half of the news about China's accomplishments is fake, that's still alot of accomplishments.

Why are you underestimating China? If you are from India, you shouldn't be underestimating China. Do you have the in depth knowledge of nuclear technology and the actual capability of China, Japan and France in regard to nuclear energy? If not, stop making statements that you cannot back up.

Why do you find the news shocking?

China sends men into space and has conducted a spacewalk. China builds Type 052C Aegis-class destroyers. China builds stealth fighters. China builds the world's-fastest 461 kph trains. China builds the world's most powerful supercomputer. China had a record 15 rocket/satellite launches in 2010; all successful as usual. Feel free to add your own superlatives.

My question is: What took you guys so long? You're amazing everywhere.

The article did not state whether the breakthrough had been "broken through" by other permanent UNSC members + Japan.

Although it is highly likely that it's only a breakthrough for China, your generalizations are groundless. And groundless generalizations my friend, evidences your poor and brown IQ. I pray for the Israeli gene pool.

14:24, May 18, 2010

The China Advanced Research Reactor (CARR), independently developed by the China Institute of Atomic Energy (CIAE), recently achieved criticality for the first time, indicating the successful completion of the CARR project.

CARR, developed to meet the needs of technological development in the 21st century, is a high-performance, multi-purpose, safe and reliable nuclear reactor with ancillary experimental terminals. The reactor, situated inside CIAE in Fangshan district, Beijing, covers an area of about 2.3 hectares and has a power of 60 megawatts.

CARR owns the most advanced technology among all neutron beam research reactors of the same type in Asia and is one of the most advanced nuclear reactors in the world. The completion of CARR marks that China has again achieved a major breakthrough in nuclear science and technology.

CARR will provide an important platform for China’s nuclear research and technology application. The reactor can be used for research in many fields such as nuclear physics and nuclear chemistry, neutron scattering experiments, testing of reactor materials and atomic fuels, neutron activation analysis and the production of radioactive species and neutron-doped silicon.

"China Advanced Research Reactor (CARR), Beijing.
A new high flux research reactor, the China Advanced Research Reactor (CARR), now is being built at China Institute of Atomic Energy (CIAE) to meet increasing demand of neutron scattering research in China.

CARR will be a 60 MW multiple purposes research reactor with unperturbed thermal neutron flux of 8x10exp14 n/sec.cm**2. A liquid hydrogen cold source at 20 K will be installed and two guide tubes will be put into the cold beam vault for transportation cold neutrons to the experimental hall. 5 of the spectrometers installed at current Heavy Water Research Reactor at CIAE will be upgraded and moved to CARR. 3 new spectrometers, a high resolution powder diffractomer, a residual stress neutron diffractometer and a horizontal scattering geometry polarized neutron reflectometer will be constructed and accommodated in the reactor hall and guide hall.

The object of CARR project is to establish a complete set of spectrometers used as the tool for neutron scattering in the fields of life science, material science, physics, chemistry and chemical engineering, mineral, environment science, industrial and engineering application with the aim to build the laboratory as a national neutron scattering key laboratory with an internationally advanced level, serving as a national neutron scattering research and training center as well as an international research center in Asia.


Neutron scattering leading group:
Group leader: President of CIAE - Prof. Zhao Zhixiang
Deputy group leader: Director of Department of Nuclear Physics Prof. Dr. Liu Weiping
Deputy group leader: Group leader of Neutron Scattering project Prof. Gou Cheng

Neutron scattering engineer group:
Group leader: Prof. Gou Cheng
Head of neutron scattering Project / deputy group leader: Prof. Dr. Chen Dongfeng
Deputy Head of neutron scattering Project / technical group leader: Dr. Liu Yuntao"

[Note: China's Advanced Research Reactor (i.e. CARR) is not to be confused with China Experimental Fast Reactor (i.e. CEFR). CARR is a neutron scattering tool. CEFR is a fast-breeder reactor to produce electricity by consuming and self-generating more nuclear fuel to enable nearly 70% efficiency in extracting energy from the uranium fuel. They serve two completely different purposes.]

China starts up first fourth generation nuclear reactor

"China starts up first fourth generation nuclear reactor
English.news.cn 2010-07-22 07:22:44

BEIJING, July 21 (Xinhua) -- Chinese scientists have succeeded in testing the country's first experimental fourth generation nuclear reactor, an expert said here on Wednesday.

The successful start up of the China Experimental Fast Reactor (CEFR) marked a breakthrough in China's fourth generation nuclear technology, and made China the eighth country in the world to own the technology, Zhang Donghui, general manager of the CEFR project, told Xinhua over phone.

China's existing 11 nuclear power generating units all use second generation of nuclear power generation technology. The country started the construction of its first third-generation pressurized water reactors using AP1000 technologies developed by U.S.-based Westinghouse in 2009.

Compared with the third generation reactors which have an utility rate of uranium of just one percent, CEFR boasts an utility rate of more than 60 percent.

A new recycling technology called pyroprocessing is also used to close the fuel cycle by separating the unused fuel from most of the radioactive waste.

"The CEFR is safer, more environment-friendly, and more economic than its predecessors," Zhang said."

China Close to Firing Up a Fast Reactor « Carbon-Nation

"The Chinese Experimental Fast Reactor is so-named because the neutrons produced in its core are not ‘moderated’ with water like those that generate heat in nearly all commercial nuclear reactors. The faster neutrons can burn down nuclear waste and even generate new fuel, promising a solution to the thorny problem of waste storage as well as energy independence.

Fast reactors have proven difficult to operate because most rely on highly flammable liquid sodium to cool the reactor, but their promised benefits keep the hope alive."

China's Fast Breeder Reactor (FBR) Program

"China's Fast Breeder Reactor (FBR) Program

原子能快堆研究中心

China began research on fast neutron breeder reactors in the mid- and late-1960s. During its basic research period from 1965 to 1987, China's research focused on fast reactor technology such as fast reactor physics, thermodynamics, sodium technology and small sodium facility. During this initial period about 12 experimental setups were established, and one sodium loop was constructed. This included a 50 kg 235U zero-power neutron setup. On June 28 June 1970, this device reached criticality. The engineering goal for the applied basic research phase of China's FBR program (1987-1993) was to successfully construct a 65 MWt (25 MWe) experimental fast reactor. Further developments were made in sodium technology, fuel and materials, fast reactor safety, and reactor design. A preliminary foundation for a fast reactor design was established, and approximately 20 experimental setups and sodium loops were built."

Nuclear Engineering International

"Nine years after construction began on the China Experimental Fast Reactor near Beijing, the reactor is close to start up. First criticality is expected before the end of 2009 and the reactor is due to be connected to the grid in June of 2010.
...
Ordering of components for CEFR began in 1997. The components were imported mainly from Russia, France, USA and UK, with imports from abroad sharing about 30% of the total systems and components budget."

China Experimental Fast Reactor Ready to Connect | Nuclear Energy Insider

"Following the start of operations for CEFR in June, the next milestone will be the commissioning of the so-called China Demonstration Fast Reactor (CDFR), planned for 2018, though initial work on the design was approved back in 2007.

The CDFR will be located in Fujian province on China’s busy and economically active eastern seaboard, opposite Taiwan.

Following CDFR, the plan is move towards a Chinese developed commercial fast reactor (CCFR), though no preliminary dates have been released for this final stage of the programme as yet – dates including 2028 and 2035 have been [mooted] but not confirmed.

Despite this, the press has reported (unconfirmed by the central government in Beijing but suggested by sources at the government-linked China Institute of Atomic Energy) that several CDFR plants should be in operation by 2030 and that China’s nuclear capacity will rise to 240-250GWe by 2050 with most of this produced by fast breeder reactors that will be introduced to replace China’s current stock of highly polluting, inefficient and costly coal fired power plants.

New record for nuclear, for China

If China does deliver the CEFR in June then it will be the only third power-generating fast reactor in operation globally."

"Reactor starts up at Ling Ao II
11 June 2010

China Guangdong Nuclear Power Company (CGNPC) has celebrated the achievement of criticality at the first reactor of the Ling Ao II nuclear power plant.

Control rods were withdrawn from the core of the pressurized water reactor on 9 June, while concentrations of boron in the coolant water were reduced to create conditions for a sustained chain reaction. CGNPC then undertook 35 hours of zero-power tests that helped it verify the performance of the reactor core as well as instrumentation and monitoring systems.

The commissioning milestone of criticality comes before start-ups and shutdowns at low power, connection to the grid and a stepped increase to full power and commercial operation in around October. At that point it would become the 12th nuclear reactor to supply power to China and take total generating capacity close to 10 GWe.

The reactor is the third CPR-1000 to be built, representing a development from a French 900 MWe design imported in the 1990s: The CPR-1000 can deliver 1080 MWe and has a design life of 60 years.

CGPC noted the increased involvement of Chinese designers and suppliers, which reached about 50 per-cent with this unit. A subsequent reactor at Ling Ao II should have 70 per-cent local content - including the first Chinese-made pressure vessel. The figure is rising beyond 80 per-cent for the 12 other CPR-1000s currently under construction and beyond those another 13 are firmly planned which should use Chinese suppliers for over 90 per-cent of parts.

Nuclear reactor pressure vessel installation

China produces own million-kilowatt-level nuclear tech - People's Daily Online

"China produces own million-kilowatt-level nuclear tech
16:31, December 20, 2010

China's first fully self-developed No. 1 unit reactor pressure vessel of the Hongyanhe Nuclear Power Station, manufactured by China First Heavy Industries (CFHI), was completed on Dec. 18 and sent to Hongyanhe of Liaoning Province.

After testing, all of the equipment's technical indicators meet the requirements, signifying that China has independently developed the capacity to create million-kilowatt nuclear equipment.

Hongyanhe Nuclear Power Station is China's first million-kilowatt nuclear power station, and it began construction during the 11th Five-Year Plan period.

In accordance with the requirements of the National Development and Reform Commission, China has now basically achieved the ability to produce domestically-made second generation million-kilowatt nuclear power equipment through the development of four units during the first phase of the project.
