CNNC
The China National Nuclear Corporation (CNNC; ) is a state-owned enterprise founded in 1955 in Beijing. CNNC's president and vice-president are appointed by the Premier of the People's Republic of China. CNNC oversees all aspects of China's civilian and military nuclear programs. According to its own mission statement, it "is a main part of the national nuclear technology industry and a leading element of national strategic nuclear forces and nuclear energy development." CNNC is a nationwide industrial conglomerate integrating science, technology, industry, and international trade. Its headquarters are in Xicheng District, Beijing.

Nuctech
Nuctech Company, Ltd (同方威视技术股份有限公司, formerly 威视股份) is a Chinese partially state-owned security inspection products company, headquartered in Beijing, created in 1997 as an offshoot of Tsinghua University. Nuctech Company's parent company, Tsinghua Tongfang, is controlled by the China National Nuclear Corporation, a state-owned company that manages China's civilian and military nuclear fuel development program. Several countries have raised concerns about contracts for security scanning equipment due to the company's partial state ownership and ties to the Chinese Communist Party and Chinese military. History Nuctech Company was founded in 1997 in Beijing as Nuctech Co, Ltd. by several professors from Tsinghua University who wanted to commercialize results of their research in container inspection technology. In 1999, the company sold inspection systems to Chinese customs and in 2001 signed its first international contracts with Australia and the U ...

District Heating
District heating (also known as heat networks or teleheating) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels or biomass, but heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as heat waste from factories and nuclear power electricity generation. District heating plants can provide higher efficiencies and better pollution control than localized boilers. According to some research, district heating with combined heat and power (CHPDH) is the cheapest method of cutting carbon emissions, and has one of the lowest carbon footprints of all fossil generation plants. Fifth-generation district heat networks do not use combustion on-site and have zero emissions of CO and NO on-site; they employ heat transfer u ...

Traveling Wave Reactor
A traveling-wave reactor (TWR) is a proposed type of nuclear fission reactor that can convert fertile material into usable fuel through nuclear transmutation, in tandem with the burnup of fissile material. TWRs differ from other kinds of fast-neutron and breeder reactors in their ability to use fuel efficiently without uranium enrichment or reprocessing, instead directly using depleted uranium, natural uranium, thorium, spent fuel removed from light water reactors, or some combination of these materials. The concept is still in the development stage and no TWRs have ever been built. The name refers to the fact that fission remains confined to a boundary zone in the reactor core that slowly advances over time. TWRs could theoretically run self-sustained for decades without refueling or removing spent fuel. History Traveling-wave reactors were first proposed in the 1950s and have been studied intermittently. The concept of a reactor that could breed its own fuel inside the react ...

TerraPower
TerraPower is an American nuclear reactor design and development engineering company headquartered in Bellevue, Washington. TerraPower is developing a class of nuclear fast reactors termed traveling wave reactors (TWR). TWR places a small core of enriched fuel in the center of a much larger mass of non-fissile material, in this case depleted uranium. Neutrons from fission in the core "breeds" new fissile material in the surrounding mass, producing Plutonium-239. Over time, enough fuel is bred in the area surrounding the core that it can undergo fission, sending neutrons further into the mass and continuing the process while the original core expires. Over a period of decades, the reaction moves from the core of the reactor to the outside, thus "travelling wave". In September 2015, TerraPower signed an agreement with state-owned China National Nuclear Corporation to build a prototype 600 MWe reactor unit at Xiapu in Fujian province, China, from 2018 to 2025. Commercial power ...

China Nuclear International Uranium Corporation
The China Nuclear International Uranium Corporation (中国国核海外铀资源开发公司) (abbreviated as Sino-U or SinoU) is a Chinese Government owned corporation involved in prospecting, and eventually mining, overseas sources of uranium. In late 2006, SinoU was spun off from the China National Nuclear Corporation (CNNC), China's state owned nuclear processing, mining, plant operation, and research agency, where it was previously the Overseas Uranium Exploitation Department of the CNNC. Operations Its first major contract was to build the Teguida, Niger-based Azelik mine and ore process plant as a joint venture with the Nigerien government run Société Minière d'Azelik. Initial estimates were that the mine would be operational in 2010. The deal struck in 2007 was part of a policy shift by then Nigerien president Mamadou Tandja to break the four decade de facto monopoly held by Areva, a French state owned nuclear company, by bringing in Sino-U as a competitor. The '' ...

Nuclear Reprocessing
Nuclear reprocessing is the chemical separation of fission products and actinides from spent nuclear fuel. Originally, reprocessing was used solely to extract plutonium for producing nuclear weapons. With commercialization of nuclear power, the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors. The reprocessed uranium, also known as the spent fuel material, can in principle also be re-used as fuel, but that is only economical when uranium supply is low and prices are high. A breeder reactor is not restricted to using recycled plutonium and uranium. It can employ all the actinides, closing the nuclear fuel cycle and potentially multiplying the energy extracted from natural uranium by about 60 times. Reprocessing must be highly controlled and carefully executed in advanced facilities by highly specialized personnel. Fuel bundles which arrive at the sites from nuclear power plants (after having cooled down for several years) are completely dissolv ...

Nuclear Fuel Cycle
The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the ''front end'', which are the preparation of the fuel, steps in the ''service period'' in which the fuel is used during reactor operation, and steps in the ''back end'', which are necessary to safely manage, contain, and either reprocess or dispose of spent nuclear fuel. If spent fuel is not reprocessed, the fuel cycle is referred to as an ''open fuel cycle'' (or a ''once-through fuel cycle''); if the spent fuel is reprocessed, it is referred to as a ''closed fuel cycle''. Basic concepts Nuclear power relies on fissionable material that can sustain a chain reaction with neutrons. Examples of such materials include uranium and plutonium. Most nuclear reactors use a moderator to lower the kinetic energy of the neutrons and increase the probability that fission will occur. This allows reactors to use material with far lower con ...
