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".
For some countries, nuclear power affords energy independence. In the words of the French, "We have no coal, we have no oil, we have no gas, we have no choice." [19] Japan—similarly lacking in indigenous natural resources for power supply—relied on nuclear power for 1/3 of its energy mix prior to the Fukushima nuclear disaster; since March 2011, Japan has sought to offset the loss of ...
Recent concerns have been expressed about safety issues affecting a large part of the nuclear fleet of reactors. In 2012, the Union of Concerned Scientists , which tracks ongoing safety issues at operating nuclear plants, found that "leakage of radioactive materials is a pervasive problem at almost 90 percent of all reactors, as are issues that ...

The Energy Department estimates the US will need approximately 700-900 GW of additional clean, firm power generation capacity to reach net-zero emissions by 2050, adding that nuclear energy ...
Here are the challenges facing the government and plant operator Tokyo Electric Power Co (Tepco) as they try to draw a line by the middle of the century under the world's worst nuclear accident ...
Nuclear energy and renewable energy have reduced environmental costs by decreasing CO 2 emissions resulting from energy consumption. [ 2 ] There is a catastrophic risk potential if containment fails, [ 3 ] which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the ...
