Pressure in Reactor No. 1 drops close to normal air pressure — Proves that ‘air’ inside reactor is escaping outside

Pressure in No.1 reactor drops close to atmosphere, NHK, June 05, 2011:

On Friday, the utility replaced the gauge with a new one and made measurements again.
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. [...]
