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
Economics of nuclear power plants but has been estimated to cost around $100 billion. Chernobyl is not yet decommissioned, different estimates put the end date between 2013 and 2020. A 2011 report for the Union of Concerned Scientists stated that "the costs of preventing nuclear proliferation and terrorism should be recognized as negative externalities of civilian nuclear power, thoroughly evaluated, and integrated into economic assessments—just as global warming emissions are increasingly identified as a cost in the economics of coal-fired electricity". When a country pursues civilian nuclear power, it is often indistinguishable whether the country's motives are honest or if it is a cover for
