Chernobyl Nuclear Power Plant in a turbine. Reactors 1 and 3 were eventually closed due to an agreement Ukraine made with the EU in 1995. Ukraine agreed to close the remaining units in exchange for EU assistance in modernizing the shelter over reactor N. 4 and improving the energy sector of the country, including the completion of two new nuclear reactors, Khmelnitski 2 and Rovno 4. Reactor N. 1 was shut down in 1996 with N. 3 following in 2000. On September 9, 1982, a partial core meltdown occurred in Reactor N. 1 at the Chernobyl plant. The extent of the damage was minor,
Nuclear power power is a safe, sustainable energy source that reduces carbon emissions. Opponents, such as Greenpeace and NIRS, contend that nuclear power poses many threats to people and the environment. Some accidents have occurred in nuclear power plants. These include the Chernobyl disaster in the Soviet Union in 1986, the Fukushima Daiichi nuclear disaster in Japan in 2011, and the more contained Three Mile Island accident in the United States in 1979. There have also been some nuclear submarine accidents. In terms of lives lost per unit of energy generated, nuclear reactors have caused the lowest number of fatalities per unit
