Japan : Pressure rises inside No.1 reactor container

From NHK News :

" Tokyo Electric Power Company is taking measures to reduce pressure inside the No.1 reactor containment vessel at the troubled Fukushima Daiichi nuclear plant.

The power company began injecting more water into the No.1 reactor on Wednesday, after temperatures on the reactor surface reached about 400 degrees Celsius, exceeding the safety limit of 302 degrees.Japan's Nuclear and Industrial Safety Agency says the influx of massive amounts of water has raised the pressure inside the reactor containment vessel.

The power company cut back on the water injection early on Thursday. This resulted in pressure inside the container dropping to 0.3585 mega-pascals, below the safety limit of 0.528 mega-pascals.The reactor temperature also dropped to 243 degrees as of 5:00 AM on Thursday."
