Pressure in No.1 reactor drops close to atmosphere
"Tokyo Electric Power Company has found that pressure inside the Number 1 reactor at its Fukushima Daiichi power plant has dropped to close to the outside atmospheric pressure. It reaffirms that the reactor has been damaged."

"The reading was 1.26 atmospheres as of 11 AM on Saturday, almost equal to normal air pressure. The company says this proves that air inside the reactor is escaping outside.
But the utility estimates that the lack of a big hole in the reactor is keeping steam inside, leading to the slightly higher interior pressure."
