Nuclear power in Ukraine year 2030, which would almost double the current amount of nuclear power capacity. Ukraine's power sector is the twelfth-largest in the world in terms of installed capacity, with 54 gigawatts (GW). Renewable energy still plays a very modest role in electrical output; in 2005 energy production was met by the following sources: nuclear (47 percent), thermal (45 percent), hydroelectric and other (8 percent). The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over
Nuclear power phase-out K. Sovacool has reported that worldwide there have been 99 accidents at nuclear power plants. Fifty-seven accidents have occurred since the Chernobyl disaster, and 57% (56 out of 99) of all nuclear-related accidents have occurred in the USA. Serious nuclear power plant accidents include the Fukushima Daiichi nuclear disaster (2011), Chernobyl disaster (1986), Three Mile Island accident (1979), and the SL-1 accident (1961). Stuart Arm states, "apart from Chernobyl, no nuclear workers or members of the public have ever died as a result of exposure to radiation due to a commercial nuclear reactor incident."
