The China syndrome (loss-of-coolant accident) is a nuclear reactor operations accident characterized by the severe meltdown of the core components of the reactor, which then burn through the containment vessel and the housing building, then (figuratively) through the crust and body of the Earth until reaching the opposite end, presumed to be in ...
The Fukushima Daiichi nuclear disaster in 2011 occurred due to a loss-of-coolant accident. The circuits that provided electrical power to the coolant pumps failed causing a loss-of-core-cooling that was critical for the removal of residual decay heat which is produced even after active reactors are shut down and nuclear fission has ceased.
Containment systems for nuclear power reactors are distinguished by size, shape, materials used, and suppression systems. The kind of containment used is determined by the type of reactor, generation of the reactor, and the specific plant needs. Suppression systems are critical to safety analysis and greatly affect the size of containment.
A new paper details two tests of a nuclear plant that can’t melt down. The durability is due to natural qualities, like insulated fuel and the density of heated gas.
The HTR-PM is a high-temperature gas-cooled (HTGR) pebble-bed reactor. While the German AVR and THTR-300, operating from 1969 to 1988, were the first pebble-bed reactors and operated at similar temperatures, the HTR-PM is the first such design using modular construction and the second small modular reactor, following Russia's Akademik Lomonosov floating plant in 2019.
The reactor in Shidao Bay, China is the world’s first gas-cooled nuclear power plant built for commercial demonstration. It is cooled by helium and can reach high temperatures of up to 750 ...
China has started commercial operations at a new generation nuclear reactor that is the first of its kind in the world, state media said on Wednesday. Compared with previous reactors, the fourth ...
As of 2020, China had 41 additional nuclear reactors planned and 168 proposed reactors under consideration. [36]: 197 China's under construction reactors accounted for 27% of worldwide reactors under construction. [36]: 197 As of at least 2023, China's goals for nuclear power expansion are the most ambitious of any country. [36]: 197
