ACPR1000
The CPR-1000, or CPR1000 (Chinese PWR) is a Generation II+ pressurized water reactor, based on the French 900 MWe three cooling loop design (M310) imported in the 1980s, improved to have a slightly increased net power output of 1,000 MWe (1080 MWe gross) and a 60-year design life. The CPR-1000 is built and operated by the China General Nuclear Power Group (CGNPG), formerly known as China Guangdong Nuclear Power. Progressively more Chinese manufactured components were used in the units; the second unit built had 70% of its equipment manufactured in China, with a 90% Chinese content target for later builds. Construction On 15 July 2010, China's first CPR-1000 nuclear power plant, Ling Ao-3, was connected to the grid, having started criticality testing on 11 June 2010. It started commercial operations on 27 September 2010, with Ling Ao-4 starting commercial operation on 7 August 2011. 18 CPR-1000 reactors have been built as of December 2019. Besides Ling Ao unit 3 & 4, the CPR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hualong One
The Hualong One ( zh , c=华龙一号 , p=Huálóng yī hào , l=China Dragon №1) is a Chinese Generation III pressurized water nuclear reactor jointly developed by the China General Nuclear Power Group (CGN) and the China National Nuclear Corporation (CNNC). The CGN version, and its derived export version, is called HPR1000. It is commonly mistakenly referred to in media as the "ACPR1000" and "ACP1000", which are in fact earlier reactors design programs by CGN and CNNC. Unit 5 of the Fuqing Nuclear Power Plant was the first Hualong One to enter commercial service on 30 January 2021. Design Hualong One is jointly developed by the China National Nuclear Corporation (CNNC) and China General Nuclear Power Group (CGN), based on the three-loop ACP1000 of CNNC and ACPR1000 of CGN, which in turn are based on the French M310. Merger of ACP-1000 and ACPR-1000 into Hualong One Since 2011, CNNC has been progressively merging its ACP-1000 nuclear power station design with the CG ...

Hongyanhe Nuclear Power Plant
The Hongyanhe Nuclear Power Plant (红沿河核电站) is located in Donggang Town, Wafangdian in Liaoning, Liaoning Province of China. The site is within the Prefecture-level city of Dalian, north of Dalian City proper. The first unit started commercial operations in June 2013. Phase I consists of four CPR-1000 reactors, which is a design developed by China from the Framatome-designed Pressurized water reactor, PWRs at the Daya Bay Nuclear Power Plant. Phase II is the first construction of two ACPR1000 reactors, a further development of the CPR-1000. This reactor will include a core catcher and double containment as additional safety measures. Progress The project was approved by the National Development and Reform Commission in April 2006, and projected to cost 23 billion Renminbi for the first two units. The cost will be shared between the China Power Investment Corporation, the China General Nuclear Power Group and two Liaoning companies. Liaoning Hongyanhe Nuclear ...

Pressurized Water Reactor
A pressurized water reactor (PWR) is a type of light-water reactor, light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary nuclear reactor coolant, coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the Nuclear fission, fission of atoms. The heated, high pressure water then flows to a Water-tube boiler, steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizo ...

Core Catcher
A core catcher is a device provided to catch the molten core material ( corium) of a nuclear reactor in case of a nuclear meltdown and prevent it from escaping the containment building. A core catcher is made from a special concrete ceramic to prevent material from trickling through; it also has a cooling mechanism to cool down the core material. The core catcher of the European Pressurized Reactor (EPR) has 170 m² expansion area and a mass of 500 t. Examples of reactor types with core catchers, besides the EPR, are: * SNR-300 (fast breeder)Areva Brochure: EPR - reference number:G-61-V1-07-GER * AES-91 / VVER-1000/428 * VVER-1200(PWR) * SWR1000 (BWR) * ESBWR ( BWR) * ABWR (BWR) * APWR ( PWR) * Atmea I (PWR) * ACPR-1000 (PWR) * EU-APR1400 (PWR) * IPWR-900 The AES-91, a project of Atomstroyexport based on the VVER-1000 design, was envisaged to be the first type of nuclear plant to have a core catcher directly underneath the reactor. Thus, in early 2011, the two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Generation III Reactor
Generation III reactors, or Gen III reactors, are a class of nuclear reactors designed to succeed Generation II reactors, incorporating evolutionary improvements in design. These include improved fuel technology, higher thermal efficiency, significantly enhanced safety systems (including passive nuclear safety), and standardized designs intended to reduce maintenance and capital costs. They are promoted by the Generation IV International Forum (GIF). The first Generation III reactors to begin operation were Kashiwazaki 6 and 7 advanced boiling water reactors (ABWRs) in 1996 and 1997. Since 2012, both have been shut down due to security concerns. Due to the prolonged period of stagnation in the construction of new reactors and the continued (albeit declining) popularity of Generation II/II+ designs in new construction, relatively few third generation reactors have been built. Overview The older Gen II reactors comprise the vast majority of current nuclear reactors. Gen III re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Generation II Reactor
A generation II reactor is a design classification for a nuclear reactor, and refers to the class of commercial reactors built until the end of the 1990s. Prototypical and older versions of PWR, CANDU, BWR, AGR, RBMK and VVER are among them. These are contrasted to reactors, which refer to the early prototype of power reactors, such as Shippingport, Magnox/UNGG, AMB, Fermi 1, and Dresden 1. The last commercial Gen I power reactor was located at the Wylfa Nuclear Power Station and ceased operation at the end of 2015. The nomenclature for reactor designs, describing four 'generations', was proposed by the US Department of Energy when it introduced the concept of generation IV reactors. The designation ''generation II+ reactor'' is sometimes used for modernized generation II designs built post-2000, such as the Chinese CPR-1000, in competition with more expensive generation III reactor designs. Typically, the modernization includes improved safety systems and a 60-year design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
