Shutdown is the state of a nuclear reactor when the fission reaction is slowed significantly or halted completely. Different nuclear reactor designs have different definitions for what "shutdown" means, but it typically means that the reactor is not producing a measurable amount of electricity or heat and is in a stable condition with very low reactivity.
Reactor unit 4 is in "hot shutdown", mainly for heating purposes. IAEA Director General Rafael Grossi says that fighting a war around a nuclear plant has put nuclear safety and security in ...
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 clean-up crew working to remove radioactive contamination after the Three Mile Island accident. Nuclear safety is defined by the International Atomic Energy Agency (IAEA) as "The achievement of proper operating conditions, prevention of accidents or mitigation of accident consequences, resulting in protection of workers, the public and the environment from undue radiation hazards".
Reactors 1, 2, 5 and 6 are in cold shutdown, while Reactor No. 3 is shut down for repair and Reactor No. 4 is in so-called hot shutdown, according to the plant.
Launch on warning (LOW), or fire on warning, [1] [2] is a strategy of nuclear weapon retaliation where a retaliatory strike is launched upon warning of enemy nuclear attack and while its missiles are still in the air, before detonation occurs. It gained recognition during the Cold War between the Soviet Union and the United States.
Europe's largest nuclear plant was captured by Russian forces in March 2022. Ukraine and Russia accuse each other of shelling around the station and the International Atomic Energy Agency (IAEA ...
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).
