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 occurred. The severity of nuclear accidents is generally classified using the International Nuclear Event Scale (INES) introduced by the International Atomic Energy Agency (IAEA). The scale ranks anomalous events or accidents on a scale from 0 (a deviation from normal operation that pose no safety risk) to 7 (a major accident with widespread effects). There have been 3 accidents of level 5 or higher in the civilian nuclear power industry, two of which, the Chernobyl accident and the Fukushima accident, are ranked at level 7. The Chernobyl accident in 1986 caused approximately 50 deaths from direct and indirect effects, and
