URGENT: Gov't eyes injecting nitrogen into reactor vessels to prevent blasts | Kyodo News
The government and Tokyo Electric Power Co. are considering injecting nitrogen into containment vessels of the Fukushima Daiichi nuclear power plant's reactors to prevent hydrogen explosions, government sources said Friday.

Huh!? The hydrogen generated during the initial water depletion should have been mostly vented by now, so does that mean that they still have hydrogen generation?

Why are they suddenly worried? does this mean that were at the point of reaction occurring again?

I recall that hydrogen is produced by the thermal decomposition of the zirconium rods. This might indicate that there is concern over the ability to maintain even the existing reduced water levels around the rods in the reactors. If they can prevent hydrogen explosions inside the containment vessel that would be good. Venting a mix of hydrogen and nitrogen should be much less vulnerable to immediate explosion than just venting hydrogen into a norma oxygen/nitrogen atmosphere.
