Fukushima Reactor 1 China Syndrome

May 25, 2011

Energy News is reporting a dramatic increase in radiation.

From commenter TraderGreg:

It entered the dry well on May 21st. Based on 15 ft of concrete, it probably will burn completely through this this week – based on the limed information that we have. Actually, based on rough calculations, it may have already burned through it, by now.

The big question is – how much rock/soil is between the concrete and the water bed?

Once we have steam/hydrogen explosion (or whatever), the huge geyser may damage the other buildings around, and it will be game over.

This has been described as an extinction level event. It may take a generation, but we are all doomed to die of cancer… unless something else gets us first.

Fukushima is out of control.

    China Syndrome is a physical impossibility.

    Nevertheless, it remains an apt term to describe what is happening:

    The term “China Syndrome” refers to a possible result of a catastrophic meltdown of a nuclear reactor. Also called a loss of coolant accident, the scenario begins when something causes the coolant level in a reactor vessel to drop, uncovering part—or all—of the fuel element assemblies. Even if the nuclear chain reaction has been stopped through use of control rods or other devices, the fuel continues to produce significant residual heat for a number of days due to further decay of fission products. If not properly cooled, the fuel assemblies may soften and melt, falling to the bottom of the reactor vessel. There, without neutron-absorbing control rods to prevent it, nuclear fission could resume but, in the absence of a neutron moderator, might not. Regardless, without adequate cooling, the temperature of the molten fuel could increase to the point where it melts through the structures containing it. Although many[who?] feel the radioactive slag would stop at or before the underlying soil, such a series of events could release radioactive material into the atmosphere and ground, potentially causing damage to the local environment’s plant and animal life.
