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".
The AP600 has passive safety features characteristic of the Generation III reactor concept. The projected core damage frequency is nearly 1000 times less than today's Nuclear Regulatory Commission (NRC) requirements, on par with plants currently being considered for construction.
The AP1000 design traces its history to two previous designs, the AP600 and the System 80.. The System 80 design was created by Combustion Engineering and featured a two-loop cooling system with a single steam generator paired with two reactor coolant pumps in each loop that makes it simpler and less expensive than systems which pair a single reactor coolant pump with a steam generator in each ...
The reactor that was hit was offline, but still contains highly radioactive nuclear fuel. Four of the other six reactors have now been taken offline, leaving only one in operation.
The United States 9/11 Commission has said that nuclear power plants were potential targets originally considered for the September 11, 2001 attacks. If terrorist groups could sufficiently damage safety systems to cause a core meltdown at a nuclear power plant, and/or sufficiently damage spent fuel pools, such an attack could lead to widespread ...
A fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing so, it bypasses the Carnot cycle and can achieve efficiencies of up to 90% instead of 40–45% attainable by efficient turbine-driven thermal reactors.
The largest nuclear power plant in Europe faces “a relatively dangerous situation” after a dam burst in Ukraine and Kyiv launches a counteroffensive to retake ground occupied by Russia, the ...
A map claiming to show the areas of the US that may be targeted in a nuclear war that originally circulated in 2015 is making the rounds again, amid the Russian war in Ukraine.. The map indicates ...
