That doesn’t sound good. I really feel for them and all they are dealing with.

Kathy:

Dr. Akihide Hidaka (the Japanese researcher who is participating in our peer review of the revised NUREG-1465 for HBU and MOX fuel) told me that at the Fukushima No. 1 NPP, the fuel could have been broken because iodine concentration in air began to be increased at the site boundary.
Containment Venting is imminent.

I am not sure what he meant by “broken.” I asked him whether the dose at the site boundaries are within regulatory limits. I have not received any answers yet.

Akihide is on loan to the Japanese Nuclear Safety Commission (NSC) from JAEA. Last night, all NSC staff slept in the office because all transportation in Toyko was shutdown.
