UPDATE
TEPCO started injecting nitrogen on Thursday into a reactor containment vessel at the Fukushima Dai-ichi nuclear power plant in an effort to prevent explosions, which could occur anytime.

TOKYO (majirox news) – TEPCO (Tokyo Electric Co) is considering injecting nitrogen into a reactor containment vessel at the Fukushima Dai-ichi nuclear plant, TEPCO said on Wednesday.

They may start Wednesday night. It would prevent the stored-up hydrogen from exploding at reactor No.1, according to TEPCO. Injecting nitrogen can reduce the amount of hydrogen in the reactor containment vessel.

“This would be the first time TEPCO is taking action to prevent a critical situation from occurring,” said NHK nuclear expert Mizuno. “They usually wait until after something happens to take action.”

Operator Of Japan Nuclear Power Plant Says Radiation-Contaminated Water Stopped
The outflow of highly radioactive water into the ocean from the troubled Fukushima Dai-ichi nuclear power plant has stopped after the injection of a chemical agent, TEPCO (Tokyo Electric Power Co.) said Wednesday.

In efforts to stop the leak, TEPCO, injected 1,500 liters of ”water glass,” or sodium silicate, and another agent near a seaside pit where the highly radioactive water had been seeping through.

However, they will keep monitoring the radiation levels of the sea water to make sure there are not any more holes or cracks at the plant.

The nuclear plant has been damaged by the earthquake and subsequent devastating tsunami on March 11.
