A nuclear meltdown (core meltdown, core melt accident, meltdown or partial core melt [2]) is a severe nuclear reactor accident that results in core damage from overheating. The term nuclear meltdown is not officially defined by the International Atomic Energy Agency [ 3 ] or by the United States Nuclear Regulatory Commission . [ 4 ]
A nuclear meltdown is a severe nuclear reactor accident that results in reactor core damage from overheating. It has been defined as the accidental melting of the core of a nuclear reactor, and refers to the core's either complete or partial collapse.
Aerosols released during this phase are primarily based on concrete-originating silicon compounds; otherwise volatile elements, for example, caesium, can be bound in nonvolatile insoluble silicates. [2] Several reactions occur between the concrete and the corium melt. Free and chemically bound water is released from the concrete as steam.
A decades-long project to clean up the remains of the Fukushima Daiichi nuclear power plant is preparing to remove damaged fuel debris from the plant's reactors, but much about what's inside them ...

United States Nuclear Regulatory Commission historian Tom Wellock notes that scram is English-language slang for leaving quickly and urgently, and he cites this as the original and most likely accurate basis for the use of scram in the ...
Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...
Nuclear fusion, the process that powers the sun and other stars, occurs when two atoms’ nuclei collide under extreme temperatures, causing a reaction that can generate incredible amounts of ...
Generator systems have been found to have cracks at the V.C. Summer nuclear plant north of Columbia. Generators are important to prevent nuclear meltdowns in an emergency.
