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
Chernobyl Nuclear Power Plant of the Object Shelter or the New Safe Confinement. No variances in radiation levels as a result of the incident were detected. The roof which collapsed was built after the Chernobyl disaster. It was later repaired. On June 17, 2017, a cyberattack affected the radiation monitoring system and took down the power plant's official website which hosts information about the incident and the area. After the explosion at Reactor N. 4, the remaining three reactors at the power plant continued to operate. The schedule for plant decommissioning is intimately wrapped with the dismantling of Reactor N. 4 and the decontamination
