List Of Small Modular Reactor Designs
Small modular reactors (SMR) are much smaller than the current nuclear reactors (300MWe or less) and have compact and scalable designs which propose to offer safety, construction, and economic benefits, and offering potential for lower initial capital investment and scalability. Summary table The stated power refers to the capacity of one reactor unless specified otherwise. Reactor designs ACP100: China In 2021, construction of the ACP100 was started at the Changjiang Nuclear Power Plant site in Hainan province. Previously, in July 2019 CNNC announced it would start building a demonstration ACP100 SMR by the end of the year. Design of the ACP100 started in 2010 and it became the first SMR project of its kind to be approved by the International Atomic Energy Agency in 2016. It is a fully integrated reactor module with an internal coolant system, with a two-year refuelling interval, producing 385MWt and about 125MWe. The 125MWe pressurised water reactor (PWR) is also ...

Small Modular Reactor
The small modular reactor (SMR) is a class of small nuclear fission reactor, designed to be built in a factory, shipped to operational sites for installation, and then used to power buildings or other commercial operations. The term SMR refers to the size, capacity and Modular design, modular construction. Reactor type and the nuclear processes may vary. Of the many SMR designs, the pressurized water reactor (PWR) is the most common. However, recently proposed SMR designs include generation IV reactor, generation IV, thermal-neutron reactors, fast-neutron reactors, Molten salt reactor, molten salt, and gas-cooled reactor models. Commercial SMRs have been designed to deliver an electrical power output as low as 5 Watt#MWe, MWe (electric) and up to 300 MWe per module. SMRs may also be designed purely for desalinization or facility heating rather than electricity. These SMRs are measured in megawatts thermal Watt#MWt, MWt. Many SMR designs rely on a modular system, allowing customer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead-cooled Fast Reactor
The lead-cooled fast reactor is a nuclear reactor design that uses molten lead or lead-bismuth eutectic as its coolant. These materials can be used as the primary coolant because they have low neutron absorption and relatively low melting points. Neutrons are slowed less by interaction with these heavy nuclei (thus not being neutron moderators) so these reactors operate with fast neutrons. The concept is generally similar to sodium-cooled fast reactors, and most liquid-metal fast reactors have used sodium instead of lead. Few lead-cooled reactors have been constructed, except for the Soviet submarine K-27 and the seven Soviet Alfa-class submarines (though these were beryllium-moderated intermediate energy reactors rather than fast reactors). Some proposed new nuclear reactor designs are lead-cooled. Fuel designs being explored for this reactor scheme include fertile uranium as a metal, metal oxide or metal nitride. The lead-cooled reactor design has been proposed as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CAP200
A cap is a flat headgear, usually with a visor. Caps have crowns that fit very close to the head. They made their first appearance as early as 3200 BC. The origin of the word "cap" comes from the Old French word "chapeau" which means "head covering". Over time, the word has evolved and changed its meaning, but it still retains its association with headwear. Caps typically have a visor, or no brim at all. They are popular in casual and informal settings, and are seen in sports and fashion. They are typically designed for warmth, and often incorporate a visor to block sunlight from the eyes. They come in many shapes, sizes, and are of different brands. Baseball caps are one of the most common types of cap. Types * Ascot cap * Ayam * Baggy green * Balmoral * Beanie (North America) * Bearskin * Beret * Biretta * Busby * Canterbury cap * Cap and bells * Cap of maintenance * Casquette * Caubeen * Caul * Coif * Combination cap (also known as a service cap) * Coppola * C ...

Candu Energy Inc
The CANDU (CANada Deuterium Uranium) is a Canadian pressurized heavy-water reactor design used to generate electric power. The acronym refers to its deuterium oxide (heavy water) moderator and its use of (originally, natural) uranium fuel. CANDU reactors were first developed in the late 1950s and 1960s by a partnership between Atomic Energy of Canada Limited (AECL), the Hydro-Electric Power Commission of Ontario, Canadian General Electric, and other companies. There have been two major types of CANDU reactors, the original design of around 500 MWe that was intended to be used in multi-reactor installations in large plants, and the optimized CANDU 6 in the 600 MWe class that is designed to be used in single stand-alone units or in small multi-unit plants. CANDU 6 units were built in Quebec and New Brunswick, as well as Pakistan, Argentina, South Korea, Romania, and China. A single example of a non-CANDU 6 design was sold to India. The multi-unit design was used only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GE Hitachi Nuclear Energy
GE Hitachi Nuclear Energy (GEH) is a provider of advanced reactors and nuclear services. It is headquartered in Wilmington, North Carolina, United States. Established in June 2007, GEH is a nuclear alliance created by General Electric and Hitachi. In Japan, the alliance is Hitachi-GE Nuclear Energy. History In 1955, the Atomic Power Equipment Department was established by GE. Two years later, in 1957, GE's first privately financed nuclear power reactor provided electricity for commercial use in Vallecitos, California. Additionally, in 1960, GE made and contributed to the Dresden Nuclear Power Station in Chicago. In the 1960s, it got involved in constructing and building the Boiling water reactor (BWR). The research into the project continued in the next 50 years resulting in production of 6 different BWR generations. In 1997, the GE-Hitachi U.S. Advanced boiling water reactor (ABWR) design was certified as a final design in final form by the U.S. Nuclear Regulatory Commissi ...

Boiling Water Reactor
A boiling water reactor (BWR) is a type of nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR). BWR are thermal neutron reactors, where water is thus used both as a coolant and as a moderator, slowing down neutrons. As opposed to PWR, there is no separation between the reactor pressure vessel (RPV) and the steam turbine in BWR. Water is allowed to vaporize directly inside of the reactor core (at a pressure of approximately 70 bars) before being directed to the turbine which drives the electric generator. Immediately after the turbine, a heat exchanger called a condenser brings the outgoing fluid back into liquid form before it is sent back into the reactor. The cold side of the condenser is made up of the plant's secondary coolant cycle which is fed by the power plant's cold source (generally the sea or a river, more rarely air). The BWR was developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BWRX-300
The BWRX-300 is a design for a small modular nuclear reactor proposed by GE Hitachi Nuclear Energy (GEH). The BWRX-300 would feature passive safety, in that neither external power nor operator action would be required to maintain a safe state, even in extreme circumstances. Technology The BWRX-300 is a smaller evolution of an earlier GE Hitachi reactor design, the Economic Simplified Boiling Water Reactor (ESBWR) design and utilizing components of the operational Advanced boiling water reactor (ABWR) reactor. Boiling water reactors are nuclear technology that use ordinary light water as a nuclear reactor coolant. Like most boiling water reactors, the BWRX-300 will use a medium pressure steam-water cycle to remove heat from the core. A distinct feature of this reactor design is that the water is circulated within the core by natural circulation. This is in contrast to most nuclear reactors which require electrical pumps to provide active cooling of the fuel. This system has adv ...
