In Regard to the Nuclear Meltdown at Fukushima Daiichi Plant:
Arnie Gundersen a U.S. nuclear engineer veteran has a lot to say about what we all have to live through during 2014:
“They are going to have difficulty in removing a significant number of the rods. There is a risk of an inadvertent criticality if the bundles are distorted and get too close to each other. The problem with a fuel pool criticality is that you cannot stop it. There are no control rods to control it. The spent fuel pool cooling system is designed only to remove decay heat, not heat from an ongoing nuclear reaction…
The rods are also vulnerable to fire should they be exposed to air...
I think TEPCO are belittling the complexity of the task...
If you think of a nuclear fuel rack as a pack of cigarettes, if you pull a cigarette straight up it will come out — but these racks have been distorted. Now when they go to pull the cigarette straight out, it’s going to likely break and release radioactive cesium and other gases, xenon and krypton, into the air…
I suspect come November, December, January we’re going to hear that the building’s been evacuated, they’ve broke a fuel rod, the fuel rod is off-gassing.”
