Later in 2007 these plans were again revised, with the EPR designs to be realized at Taishan, and the established CPR-1000 reactor design (as already used at Ling Ao) selected for Yangjiang. Ground was broken for the plant in February 2008; the first concrete for the first unit was poured on 16 Dece ... [...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] |

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.

Fukushima Nuclear Disaster
The was a nuclear accident in 2011 at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. The proximate cause of the disaster was the 2011 Tōhoku earthquake and tsunami, which occurred on the afternoon of 11 March 2011 and remains the most powerful earthquake ever recorded in Japan. The earthquake triggered a powerful tsunami, with 13–14-meter-high waves damaging the nuclear power plant's emergency diesel generators, leading to a loss of electric power. The result was the most severe nuclear accident since the Chernobyl disaster in 1986, classified as level seven on the International Nuclear Event Scale (INES) after initially being classified as level five, and thus joining Chernobyl as the only other accident to receive such classification. While the 1957 explosion at the Mayak facility was the second worst by radioactivity released, the INES ranks incidents by impact on population, so Chernobyl (335,000 people evacuated) and Fukushima (154,000 evacuate ...
