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
Environmental impact of nuclear power of global nuclear power capacity. A release of radioactive materials followed the 2011 Japanese tsunami which damaged the Fukushima I Nuclear Power Plant, resulting in hydrogen gas explosions and partial meltdowns classified as a Level 7 event. The large-scale release of radioactivity resulted in people being evacuated from a 20 km exclusion zone set up around the power plant, similar to the 30 km radius Chernobyl Exclusion Zone still in effect. But published works suggest that the radioactivity levels have lowered enough to now have only a limited impact on wildlife. In Japan, in July 2016, Fukushima Prefecture announced that
