Leaks have been a persistent problem at the plant since it was struck by an earthquake and tsunami on 11 March. Three reactors operating at the time of the quake went into meltdown after the tsunami wiped out emergency generators designed to circulate water through the cores. TEPCO recently admitted that all three units probably suffered complete meltdowns before workers could flood them with seawater. [...]
[T]oday Reuters reports that the storage tanks appear to be leaking.
And that's just the start of the bad news because the reactors themselves appear to be leaking as well. TEPCO initially hoped that the leaks were largely coming from pipes that could be repaired, but they now concede that both the reactors' pressure vessels and primary containment vessels, which are designed to contain an accident, are probably leaking water. [...]
Given all these problems it may be no surprise that some scientists are simply floating the idea of turning Fukushima into a nuclear graveyard. It would be a simple solution, but given the plant's location on the coast, storing the waste there for millenia may be unrealistic.
