What is the latest on the attempts to cool the reactors?
Plant workers are using the improvised technique of pumping seawater with added boron (which slows down nuclear fission) into the reactors at Fukushima Daiichi. As of Thursday in Japan, officials said that a hydrogen explosion has occurred in a second building which contains the hot nuclear reactor core. The containment vessel, in which the reactor is held, may have been breached at the No. 2 and 3 reactors, according to a New York Times report today. The explosions that have occurred are likely hydrogen explosions when hydrogen from the water mixes with the metal cladding over the uranium rods.
