ASTRID (reactor)
ASTRID (''Advanced Sodium Technological Reactor for Industrial Demonstration'') was a proposal for a 600 MW sodium-cooled fast breeder reactor ( Generation IV), proposed by the Commissariat à l'énergie atomique (CEA). It was to be built on the Marcoule Nuclear Site in France. It was the successor of the three French fast reactors Rapsodie, Phénix and Superphénix. The main goals of ASTRID were the multi-recycling of plutonium, aiming at preserving natural uranium resources, minor actinide transmutation, aiming at reducing nuclear waste, and an enhanced safety comparable to Generation III reactors, such as the EPR. It was envisaged as a 600 MW industrial prototype connected to the grid. A commercial series of 1500 MW SFR reactors was planned to be deployed around 2050. As of 2012, the project involved 500 people, with almost half among industrial partners. Those included Électricité de France, Areva, Alstom Power Systems, Comex Nucléaire, Jacobs France, Toshiba and Bouyg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marcoule Nuclear Site
Marcoule Nuclear Site () is a nuclear facility in the Chusclan and Codolet communes, near Bagnols-sur-Cèze in the Gard department of France, which is in the tourist, wine and agricultural Côtes-du-Rhône region. The plant is around 25 km north west of Avignon, on the banks of the Rhone. Operational since 1956, Marcoule is a gigantic site run by the atomic energy organization Commissariat à l'Énergie Atomique (CEA) and Areva NC and is known as CEA VALRHO Marcoule. The first industrial and military plutonium experiments took place in Marcoule. Diversification of the site was started in the 1970s with the creation of the Phénix prototype fast breeder reactor, which was operational until 2009, and is nowadays an important site for decommissioning nuclear facilities activities. the Phénix reactor was planned to be succeeded by the sodium-cooled fast reactor ASTRID (Advanced Sodium Technical Reactor for Industrial Demonstration), foreseen to become operational in t ...

EPR (nuclear Reactor)
The EPR is a Generation III reactor, Generation III+ pressurised water reactor design. It has been designed and developed mainly by Framatome (part of Areva between 2001 and 2017) and Électricité de France (EDF) in France, and by Siemens in Germany. In Europe, this reactor design was called European Pressurised Reactor, and the internationalised name was Evolutionary Power Reactor, but it has been simplified to EPR. The first operational EPR unit was China's Taishan Nuclear Power Plant, Taishan 1, which started commercial operation in December 2018. Taishan 2 started commercial operation in September 2019. European units have been so far plagued with prolonged construction delays and substantial cost overruns. The first EPR unit to start construction, at Olkiluoto Nuclear Power Plant#Unit 3, Olkiluoto in Finland, originally intended to be commissioned in 2009, started commercial operation in 2023, a delay of fourteen years. The second EPR unit to start construction, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Metal Fast Reactors
Liquid is a state of matter with a definite volume but no fixed shape. Liquids adapt to the shape of their container and are nearly incompressible, maintaining their volume even under pressure. The density of a liquid is usually close to that of a solid, and much higher than that of a gas. Therefore, liquid and solid are classified as condensed matter. Meanwhile, since both liquids and gases can flow, they are categorized as fluids. A liquid is composed of atoms or molecules held together by intermolecular bonds of intermediate strength. These forces allow the particles to move around one another while remaining closely packed. In contrast, solids have particles that are tightly bound by strong intermolecular forces, limiting their movement to small vibrations in fixed positions. Gases, on the other hand, consist of widely spaced, freely moving particles with only weak intermolecular forces. As temperature increases, the molecules in a liquid vibrate more intensely, causing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Power In Japan
Nuclear power generated 5.55% of Japan's electricity in 2023. The country's nuclear power industry was heavily influenced by the Fukushima accident, caused by the 2011 Tōhoku earthquake and tsunami. Before 2011, Japan was generating up to 30% of its electrical power from nuclear reactors. After the Fukushima accident, all reactors were shut down temporarily. , of the 54 nuclear reactors present in Japan before 2011, there were 33 operable reactors but only 13 reactors in 6 power plants were actually operating. A total of 24 reactors are scheduled for decommissioning or are in the process of being decommissioned. Others are in the process of being reactivated, or are undergoing modifications aimed to improve resiliency against natural disasters; Japan's 2030 energy goals posit that at least 33 will be reactivated by a later date. The Fukushima accident hardened attitudes toward nuclear power. In June 2011, immediately after the accident, more than 80% of Japanese said they wer ...

Nuclear Power In France
Since the mid-1980s, the largest source of Electricity sector in France, electricity in France has been nuclear power, with a generation of 379.5 terawatt-hour, TWh in 2019 and a total electricity production of . In 2018, the nuclear share was 71.67%, the highest percentage in the world. Since June 2020, it has 56 operable reactors totalling 61,370 Watt#MWe, MWe, one under construction (1630 MWe), and 14 shut down or in decommissioning (5,549 MWe). In May 2022, EDF reported that twelve reactors were shut down and being inspected for stress corrosion, requiring EDF to adjust its French nuclear output estimate for 2022 to 280–300 TWh; the estimate of the impact of the decrease in output on the Group's EBITDA for 2022 was assessed to be billion. Électricité de France (EDF)the country's main electricity generation and distribution company – manages the country's 56 Nuclear fission#Fission reactors, power reactors.
