The Event Is Getting Old and Repeated

I see eventually all the reactors there will melt down. However, the longer time they delay it, the less damage.

All depends on the containment shell getting compromised badly. So far there is no evidence one way or the other.
The reactor at Chernobyl had NO such shell! Result was major radiation fallout over many neighboring countries.
The reactor at Three Mile Island never got its containment shell compromised, result was minor radiation leaks
and no fatalities.

I have heard two different news broadcasts that have mentioned that cesium has been detected. This is a fission product which means that the the containment somewhere has been breached. I don't like what I am hearing.

Not necessarily. Note that the cooling medium comes in direct contact with the fuel rods and thus is radiation
contaminated. And all the sea water they are pumping into the reactor means the exiting water is contaminated.
And that is enough to detect radiation levels on Geiger counters or similar devices.

The real lethal fallout of Gamma rays comes from exposure of the fuel rods. When cooling system fails, those rods
go into uncontrolled fission mode and get extremely hot and can melt through the containment.

Then we have a genuine China Syndrome. But there is no evidence that has already occured. The possibility is
always there.

This reactor is a 40 year old design with steel containment. The newer reactors have a better containment design.
This reactor is a GE design and the story goes some scientists resigned because they were not satisfied with the
containment design.

Just turned on CNN - they are talking about pulling the 50 remaining workers out of the facility. These people are heros and will probably not live long. I used to sample ground water around around a nuclear plant - they had a boron leak from their spent storage tanks - just an alpha source with heavy water - not a big deal - but my radiation badge would fill in one day and I could not go back to a nuclear facility for a year - great - I didn't have to sample again for another year. Cesium on the other hand is a gamma source and a fission product. A small speck in your lungs (<0.45 microns which is the filtering capacity of most gas masks) is a gamma source and will kill tissue fast. Not good. They need to begin to bring in air force dumping lead pellets and lots of sand - but if this melts down to the water table which has got to be only a few feet below grade - it will blow and big time - Krakatoa style. I believe the potential for a nuclear winter is possible. Its time to pray. Mary Anne

Chernobyl was as bad as it gets and did not result in a nuclear winter! That said, I would not want to be within 100 miles
of the reactor site. Also can you believe they designed storage of spent fuel rods on top of the reactor! Fortunately that practice
is no longer followed.

Chernoble blew out and up, the reactor - literally blew the reactor into the air - not down into the ground - there was no melt down into the water table which will produce a huge pressure release. The workers at the plant are in grave danger and if hurt or killed and no one will enter the plant with the skills to deal with this - the system is overwhelmed. It's curious that once the EQ occurred that the control rods were not immediately brought up via a computer program and fast unless the EQ did damage to the system that would not allow the rods to be raised (a shift or bend in the critical mass shaft line) even though they still had power until the tsunami hit - which would have taken little time - literally seconds to pull a control rod in an emergency.

Some of the reports just don't give enough details
