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 sarcophagus seeping through the reactor's floor into the soil. A new containment device will allow the sarcophagus to be dismantled and radioactive material to be removed. The New Safe Confinement was expected to replace the existing sarcophagus in 2015. However, delays and a €100 million funding gap caused a yearlong delay, before being moved into place in November 2016. Chernobyl Nuclear Power Plant sarcophagus The Chernobyl Nuclear Power Plant sarcophagus or Shelter Object () is a massive steel and concrete structure covering the nuclear reactor number 4 building of the Chernobyl Nuclear Power Plant. It was designed to limit radioactive contamination
