 As officials scrambled to determine the source of the radioactive water, chief Cabinet Secretary Yukio Edano repeated Monday that the contaminated water in Unit 2 appeared to be due to a temporary partial meltdown of the reactor core.end quote.

Though I am a little surprised that the partial meltdown is occuring in Reactor number 2 in order to have 100,000 times normal radiation in the water it makes sense that there has been at least a partial meltdown for radiation to be this high.

However, all information up until now was indicating that the 100,000 times higher reading was in the plutonium reactor (#3) not the uranium reactor(#2). So, did number 2 have a partial meltdown or did number 3? Or is it both?
