The explosion was a pressurized hydrogen gas explosion. They let out too much superheated steam from the reactor at the same time they were drying to flood the core with seawater mixed with boric acid.
Luckily this didn't cause enough damage to the reactor vessel so for now it seems the fuel is still cooling down and should be safe to go in there in about a week
However the reactor core is now directly exposed to the outside. The slowly video shows the containment buildings roof being blown off.
This is NOT the same incident as Chernobyl.
They already slammed all the control rods into the core. The problem is the core takes a long time to cool down if you can't run enough chilled water through it so it was still creating super pressurized steam.
Chronobyl was a complete core meltdown with a steam explosion inside the reactor vessel itself with a runaway reaction of fuel. That spewed contamination everywhere.
3 Mile Island was also just as serious since half the fuel decomposed and it came very close to breeching the reactor vessel.
If the Fuki reactor is mostly stable with miniml damage it may be possible to wait for criticality to come to a complete halt and the fuel can be removed, the containment building to be repaired and the reactor to be repaired.
