Nuclear power plant explosion following earthquake tsunami in Japan

Fukushima Daiichi nuclear power plant had an explosion today after the nuclear core could not cool down due to lack of cooling system, which went down due to the earthquake damage. Though the plant crew tried to bring the reactor’s temperature down during the last 24 hours, the manual effort was not enough compared to the coolant requirements for the nuclear reactor. And the explosion of the reactor building is an indication that manual cooling was not successful, and now radiation leakage is on. Workers at the Fukushima Daiichi plant plan to flood the reactor containment structure with sea water to bring the reactor’s temperature down to safe levels, which may take two days. Radiation levels are said to have fallen since the explosion but authorities have expanded the evacuation to include a radius of 20 km. Continue reading
