What is a Nuclear Meltdown - Nuclear Power Info What is a Meltdown? A nuclear meltdown is the worst case scenario for a nuclear power plant, causing widespread releases of deadly radiation into the environment that can spread hundreds of miles away impacting wildlife as well as humans This type of accident is known under term a nuclear meltdown (core meltdown), but this is not officially defined by the International Atomic Energy Agency or by the Nuclear Regulatory Commission. The core melt accident is a severe nuclear reactor accident that results in core damage from overheating In a nuclear meltdown, we're faced with a reactor burning out of control, to the point where it sustains damage from its own heat. Typically, this stems from a loss of coolant accident ( LOCA ). If coolant circulation through the reactor core slows or stops altogether, the temperature goes up 11 Nuclear Meltdowns and Disasters Nuclear Meltdowns and Disasters.
