I for one, hope that the post is rubbish.
Obviously, I am just a layperson, but it seems to me that only one thing could account for a surge in the radiation readings at the plant. That would
be a change in the physical disposition
of the nuclear fuel, which has resulted in more fissionable material coming into closer proximity.
Assuming that the monitoring equipment is working properly, then we can take it as a given that something physical has changed within the reactor to
bring fuel closer together.
Here is one scenario. Concrete in the containment vessel of the reactor has deteriorated because of a combination of heat and radioactivity. Because
of the water being pumped into the vessel, the heat has hitherto not been excessive for more than short periods. However with the passage of time,
even this lower level of heat, together with continued radioactive decay of the fuel has caused a noticeable erosion of the concrete under the
This erosion has created a depression into which melted fuel has begun to settle. The effect of this is twofold: one, there is a speedup of the
nuclear fission process due to the gathering
of fuel into a pocket which concentrates fissionable material, thus increasing the rate of the
reaction, thus increasing the radiation readouts.
The second effect of this situation is to create a physical deployment of the fuel like one would see of soup in a bowl. The cooling water would now
be unable to reach part of the fuel and would be less effective, like blowing on the surface
of a bowl of soup, rather than being able to
aerate the whole mass. This leads to increased heat, and increased deterioration of the containment vessel from both the increased heat and the
This is extremely serious and could lead to the scenario predicted in the post I quoted.
Reliable information has been scarce from the beginning of the Fukushima incident, for a number of reasons, some of which are beyond the control of
the authorities. Obviously all of us are hypothesizing to some extent, but the sudden surge in radiation levels, if not the result of a failure of
monitoring systems, has got to signal a significant physical
change within the reactor.
