When you pass Ridiculously Critical and start emitting plaid, we'll know to take cover.
It's nice that we have a broad enough user base that we have folks who're conversant in almost any given field for accessible, local expertise. TEPCO's website seems to be pretty forthcoming with frequent status updates, as well.
Driving home Friday evening, I heard an ABC Radio News' 'nuclear expert' state that the reactor 'might explode'. There wasn't much detail in the report, but the clear implication was that a weapons-type explosion was imminent. Nuc physics and engineering isn't my field, but even as an interested layman I know that that just isn't going to happen- even in a worst-case scenario. What passes for news coverage in this country is a national embarrassment.
“Driving home Friday evening, I heard an ABC Radio News’ ‘nuclear expert’ state that the reactor ‘might explode’.” I’d be more concerned about his head exploding. The reactor won’t.
