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 ...
China's State Council approved the construction of six Hualong One units for Ningde (5 & 6), Shidaowan (1 & 2), and Zhangzhou (3 & 4). There are five [ 24 ] Hualong One reactors planned for Pakistan , four reactors are planned at Karachi Nuclear Power Complex [ 25 ] [ 26 ] [ 27 ] and one reactor at Chashma Nuclear Power Plant , out of which two ...
Passive nuclear safety is a design approach for safety features, implemented in a nuclear reactor, that does not require any active intervention on the part of the operator or electrical/electronic feedback in order to bring the reactor to a safe shutdown state, in the event of a particular type of emergency (usually overheating resulting from a loss of coolant or loss of coolant flow).
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.
The CFR-600 (Xiapu fast reactor pilot project) is a sodium-cooled pool-type fast-neutron nuclear reactor under construction in Xiapu County, Fujian province, China, on Changbiao Island. [ 1 ] [ 2 ] It is a generation IV demonstration project by the China National Nuclear Corporation (CNNC).
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.
A core catcher is a device provided to catch the molten core material 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 thermally resistant concrete ceramic to prevent nuclear core material from melting through the core catcher; it also has a cooling ...
At just 136 grams (4.8 oz), the tubers weigh less than half that of a typical potato in China, where the most popular varieties are often t China scientists rush to climate-proof potatoes Skip to ...
