the nuclear situation in japan is getting worse with every statement they make to the media. Basically once a nuclear reactor is shutdown there is still a need for continuous cooling of the fuel due to "decay" heat. the fuel, even when not undergoing fission reaction, creates a lot of decay heat and if let uncooled will heat up to dangerous levels. When they lost their primary cooling system, the secondary and the back-up power sources after the quake that meant adding straight sea water was the last ditch attempt to cool the fuel. When you rapidly shutdown a reactor there is a build of a lot of different gasses and addition of sea water had also produced high levels of hydrogen gas. hydrogen gas is highly explosive between the range of 4-75% concentration, which is what seems to have caused the explosion at one of the plants.
the explosion itself, they say (lets hope its true), was in an outer concrete structure and did not breach containment (a "boundary" that contains the reactor core and its radioactive sub-systems). The major worry should be the fact that one of the meters sensed Cesium in the air, although in small amounts. cesium is a byproduct of fission reaction and is only contained within the fuel bundle. failed fuel, one where inner radioactive byproducts are released outside the fuel package itself, is not an unusual situation. at my work we have systems that monitor for failed fuel, then we remove that particular fuel and replace it with fresh fuel. if the cesium detected isn't from any build up from the past, then it becomes worrying because it points to at least some of the fuel melting its structure. this means that the coolant inside the reactor core evaporated enough to exposure top layers of the fuel.
they had earlier stated that they released small amounts of steam into the atmosphere, which is a definite release of radioactivity. the solution though, is dilution. its just a pressure relief operation and the consequence will be rather minor. but lets all hope they can somehow gain control of emergency cooling. or that the engineers dont confirm a partial meltdown and progressing further south.

It is amazing seeing the media spread fears that the explosion was the reactor itself exploding. The containment structure is designed to handle whatever pressure a reactor loss of coolant accident would produce.

Update:
TBS having a conference right now...something about preventing a meltdown and using sea. water ...2/4 pumps working....radiation level decreasing....not much new info just a
bunch of figures that I don't understand

don't worry bros this won't be another chernobyl but i expected japanese nuclear reactors to be able to withstand this, no way it would have been built otherwise. they design these things around worse case scenarios, how was an 8.9 earthquake and tsunami not in the equation...

They were and that is the reason it isn't worse. The problem is that they lost their diesels, for a reason yet unknown. If the diesels were able to kick in when the reactor tripped and off-site power was lost then nothing would have happened. Core cooling would have been maintained.
