Japanese Plug Nuclear Plant Leak

Sounds good eh? And it is, it is awesome news. But the problem now is Hydrogen buildup within one of the containment vessels, this is not so good.
If they can not properly treat this situation and get it under control we will have a Chernobyl style situation.
Let's hope they are already building the sarcophagus for this one.

VOA
Troubles continue at Japan's crippled nuclear plant, where technicians believe they have solved one big problem but are confronting another.

Officials said Wednesday they have finally stopped a leak of radioactive water from the Fukushima power station that was raising radiation in the nearby ocean to millions of times the legal limit.

But now they are worried about a build-up of hydrogen inside the containment vessel at another of the plant's six reactors, creating the risk of an explosion that could release large amounts of radiation into the atmosphere. Plant officials said they may pump nitrogen into the reactor in an attempt to halt the chemical reaction.
