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 ...
Also 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
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.
Globally, there have been at least 99 (civilian and military) recorded nuclear power plant accidents from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define nuclear energy accidents that must be reported), totaling US$20.5 billion in property damages.
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 ...
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.
China is planning to build a thorium-based nuclear reactor that could be cleaner and safer than conventional options. China plans to build the first 'clean' commercial nuclear reactor Skip to main ...
Corium may be completely retained by the reactor vessel, or the reactor floor or some of the instrument penetration holes can be melted through. [9] The thermal load of corium on the floor below the reactor vessel can be assessed by a grid of fiber optic sensors embedded in the concrete. Pure silica fibers are needed as they are more resistant ...
