The Hydrogen Explosions at Fukushima nuclear complex in Japan was result of the effort to prevent the meltdown of the core.
The core which contains fuel rods is inside a 6 inches thick stainless steel vessel.
Water is being injected into the vessel to keep the temperature for rising to the level were it will melt down.
The blast actually lessened pressure building inside the troubled reactor, and officials said the all-important containment shell - thick concrete armor around the reactor - had not been damaged.
In that case, the uranium core can melt through the outer containment shell, releasing radioactive byproducts like iodine and cesium. That endangers the environment and people nearby.

This process results in generation for steam and hydrogen and in order to release the pressure inside the vessel it released in to atmosphere.
The hydrogen combines with atmospheric oxygen resulting in big explosions.
