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 in Russia Nuclear power in Russia Russia is one of the world's largest producers of nuclear energy. In 2018 total electricity generated in nuclear power plants in Russia was 202.87 TWh, 20,8% of all power generation. The installed gross capacity of Russian nuclear reactors is 31,315 MW by December 2018. Russia has made plans to increase the number of reactors in operation from 31 to 59. Old reactors will be maintained and upgraded, including RBMK units similar to the reactors at Chernobyl. The Russian energy strategy of 2003 set a policy priority for reduction in natural gas based power supply, aiming to
