Title: UPDATE ON FUKUSHIMA

Chris Harris, former licensed Senior Reactor Operator and engineer: Proof that fuel fragments were “sneezed” out of the Unit 1 Fukushima Reactor and into the Torus.
I don’t agree with Arnie’s analysis where he states that the fuel fragments have left the Containment based solely on radiation levels. Such radiation levels (92 R/hr) might come from a piece of fuel stuck inside the Torus. The gamma ray detector used by TEPCO would still be influenced by the strong radiation field right through the wall of the Torus.In the long run it doesn’t matter because the fuel fragments and byproducts are being transported outside the Containment and into filters in the make-shift cooling systems. This is why any core damage is intolerable. [...]
