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
Balakovo Nuclear Power Plant which ameliorates radiation damage and extends service life by between 15 and 30 years. This had been demonstrated on unit 1. On 27 June 1985 during startup of the first reactor unit, a human error (later attributed to inexperience and haste) unexpectedly opened a pressurizer relief valve, and 300 °C steam entered the staff work area. Fourteen people were killed. This event is cited as one of the predecessors of the Chernobyl disaster. Balakovo Nuclear Power Plant Balakovo nuclear power station ( []) is located in the city of Balakovo, Saratov Oblast, Russia, about 900 kilometers south-east of Moscow. It
