CFR-600
The CFR-600 is a sodium-cooled pool-type fast-neutron nuclear reactor under construction in Xiapu County, Fujian province, China, on Changbiao Island. It is a generation IV demonstration project by the China National Nuclear Corporation (CNNC). The project is also known as Xiapu fast reactor pilot project. Construction of the reactor started in late 2017. The reactor will have an output of 1500 MWth thermal power and 600 MW electric power. The fuel will be supplied by TVEL, subsidiary of Rosatom, according to the agreement signed i2019 The CFR-600 is part of the Chinese plan to reach a closed nuclear fuel cycle. Fast neutron reactors are considered the main technology in the future for nuclear power in China. A larger commercial-scale reactor, the CFR-1000, is also planned. On the same site, the building of a second 600 MW fast reactor CFR-600 was started in December 2020 and four 1000 MW CAP1000 are proposed.CCCC-FHDI wins bid for quot;feasibility study of offsho ...

Pool-type LMFBR
A sodium-cooled fast reactor is a fast neutron reactor cooled by liquid sodium. The initials SFR in particular refer to two Generation IV reactor proposals, one based on existing liquid metal cooled reactor (LMFR) technology using mixed oxide fuel (MOX), and one based on the metal-fueled integral fast reactor. Several sodium-cooled fast reactors have been built and some are in current operation, particularly in Russia. Others are in planning or under construction. For example in 2022, in the USA, TerraPower (using its Traveling Wave technology) is planning to build its own reactors along with molten salt energy storage in partnership with GEHitachi's PRISM integral fast reactor design, under the ''Natrium'' appellation in Kemmerer, Wyoming. Aside from the Russian experience, Japan, India, China, France and the USA are investing in the technology.

Generation IV Reactor
Generation IV reactors (Gen IV) are six nuclear reactor designs recognized by the Generation IV International Forum. The designs target improved safety, sustainability, efficiency, and cost. The most developed Gen IV reactor design is the sodium fast reactor. It has received the greatest share of funding that supports demonstration facilities, as well as two commercial reactors in Russia. One of these has been in commercial operation since 1981. Its principal Gen IV features relates its sustainable closed fuel cycle. Moir and Teller consider the molten-salt reactor, a less developed technology, as potentially having the greatest inherent safety of the six models. The very-high-temperature reactor designs operate at much higher temperatures than prior generations. This allows for high temperature electrolysis or for sulfur–iodine cycle for the efficient production of hydrogen and the synthesis of carbon-neutral fuels. The first commercial plants are not expected before 2040 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fast-neutron Reactor
A fast-neutron reactor (FNR) or fast-spectrum reactor or simply a fast reactor is a category of nuclear reactor in which the fission chain reaction is sustained by fast neutrons (carrying energies above 1 MeV or greater, on average), as opposed to slow thermal neutrons used in thermal-neutron reactors. Such a fast reactor needs no neutron moderator, but requires fuel that is relatively rich in fissile material when compared to that required for a thermal-neutron reactor. Around 20 land based fast reactors have been built, accumulating over 400 reactor years of operation globally. The largest of this was the Superphénix Sodium cooled fast reactor in France that was designed to deliver 1,242 MWe. Fast reactors have been intensely studied since the 1950s, as they provide certain decisive advantages over the existing fleet of water cooled and water moderated reactors. These are: * More neutrons are produced when a fission occurs, resulting from the absorption of a fast neutron, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Experimental Fast Reactor
The China Experimental Fast Reactor (CEFR) is China's first fast nuclear reactor, and is located outside Beijing at the China Institute of Atomic Energy. It aims to provide China with fast-reactor design, construction, and operational experience, and will be a key facility for testing and researching components and materials to be used in subsequent fast reactors. The reactor achieved first criticality on July 21, 2010 and started generating power a year later on July 21, 2011. In October 2012 Xinhua announced that the CEFR has passed official checks. The CEFR was brought to full power at 5.00pm on 15 December 2014 and operated at this level continuously for three full days. CEFR is a 65 MW thermal, 20 MW electric, sodium-cooled, pool-type reactor with a 30-year design lifetime and a target burnup of 100 MWd/kg. The CEFR was built by Russia's OKBM Afrikantov in collaboration with OKB Gidropress, NIKIET and Kurchatov Institute. The CEFR project was approved by the Chinese Sta ...

Nuclear Power In China
China is one of the world's largest producers of nuclear power. The country ranks third in the world both in total nuclear power capacity installed and electricity generated, accounting for around one tenth of global nuclear power generated. Nuclear power contributed 4.9% of the total Chinese electricity production in 2019, with 348.1 TWh. As of September 2022, China operates a total of 53 nuclear reactors, with a total capacity of 55.6 gigawatt (GW). This was short of the previous target of 58GW of installed capacity by 2020. More than 20 reactors are under construction with a total capacity of 24.2 GW. Nuclear power has been looked into as an alternative to coal due to increasing concerns about air quality, climate change and fossil fuel shortages. The China General Nuclear Power Group has articulated the goal of 200 GW by 2035, produced by 150 additional reactors. China has two major nuclear power companies, the China National Nuclear Corporation operating mainly in no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Integral Fast Reactor
The integral fast reactor (IFR, originally Liquid metal cooled reactor, advanced liquid-metal reactor) is a design for a nuclear reactor using fast neutrons and no neutron moderator (a Fast-neutron reactor, "fast" reactor). IFR would breed more fuel and is distinguished by a nuclear fuel cycle that uses nuclear reprocessing#Pyroprocessing, reprocessing via electrorefining at the reactor site. The U.S. Department of Energy began designing an IFR in 1984 and built a prototype, the Experimental Breeder Reactor II. On April 3, 1986, two tests demonstrated the safety of the IFR concept. These tests simulated accidents involving loss of coolant flow. Even with its normal shutdown devices disabled, the reactor shut itself down safely without overheating anywhere in the system. The IFR project was canceled by the united States Congress, US Congress in 1994, three years before completion. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BN-1200 Reactor
The BN-1200 reactor is a sodium-cooled fast breeder reactor project, under development by OKBM Afrikantov in Zarechny, Russia. The BN-1200 is based on the earlier BN-600 and especially BN-800, with which it shares a number of features. The reactor's name comes from its electrical output, nominally 1220 MWe. Originally part of an aggressive expansion plan including as many as eight BN-Reactors starting construction in 2012, plans for the BN-1200 were repeatedly scaled back until only two were ordered. The first was to begin construction at the Beloyarsk nuclear power plant in 2015, with initial commissioning in 2017, followed by a second unit at the same location. A possible new station known as South Ural would host another two BN-1200s at some future point. In 2015, after several minor delays, problems at the recently completed BN-800 indicated a redesign of the fuel was needed. Construction of the BN-1200 was put on "indefinite hold", and Rosenergoatom stated that no d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
