[ RadSafe ] TOKYO (AP) - Japanese authorities will release slightly radioactive vapor to ease pressure

[WesVanPelt at verizon.net]

You can get up-to-date information on the two Japanese reactors that are in
trouble from the IAEA at
http://www.iaea.org/press  
I pasted the lasted press announcement below...

The more disturbing is the increase in pressure in Unit 1 containment and
the decision to vent radioactive gas.

Japanese authorities have informed the IAEA's Incident and Emergency Centre
(IEC) that officials are working to restore power to the cooling systems of
the Unit 2 reactor at the Fukushima Daiichi nuclear power plant.  Mobile
electricity supplies have arrived at the site.

Japanese officials have also reported that pressure is increasing inside the
Unit 1 reactor's containment, and the officials have decided to vent the
containment to lower the pressure.  The controlled release will be filtered
to retain radiation within the containment.

Three reactors at the plant were operating at the time of the earthquake,
and the water level in each of the reactor vessels remains above the fuel
elements, according to Japanese authorities.

The IAEA's IEC continues to liaise with the Japanese authorities, and is in
full response mode to monitor the situation closely round the clock.
