Steam explosion major cause of human fatalities in volcanic eruptions. The 1986 Chernobyl nuclear disaster in Soviet Union was feared to cause major steam explosion (and resulting Europe-wide fallout) upon melting the lava-like nuclear fuel through the reactor's basement towards contact with residue fire-fighting water and groundwater. The threat was averted by frantic tunneling underneath the reactor in order to pump out water and reinforce underlying soil with concrete. When a pressurized container such as the waterside of a steam boiler ruptures, it is always followed by some degree of steam explosion. A common operating temperature and pressure for a marine boiler
Solar power in Ukraine demolished afterwards. Solar power in Ukraine Solar power in Ukraine is obtained from photovoltaics or solar thermal energy. In 2011, 90% of electricity came from nuclear and coal. In order to reduce this, Ukraine adopted a feed-in tariff (FIT) which is one of the highest in the world - UAH 5.0509 (EUR 0.46) per kWh. Europe's largest solar park at the time, the 100 MW Perovo Solar Park was completed at the end of 2011. In 1985 there was (SES-5, 5MW), first and last build solar station in Soviet Union near town of Shcholkine in Crimea. It was stopped in
