Broken Reactor Components
A nightmare confirmed:
Steam tube degradation is increasingly likely to cause a nuclear meltdown
Part II - what would occur in a meltdown
|During a cascading tube rupture, radioactive primary water will flash into steam in the secondary water loop.|
|Steam-line pressure relief valves outside the containment vessel will open, and vent radioactive steam to the atmosphere.|
|As primary water hemorrhages into the
secondary loop, primary water pressure will drop. This will cause water
in the core to boil. Steam pressure inside the core will force water out,
and the core, no longer cooled by water, will melt.
|Molten fuel will collect at the bottom of the reactor
vessel and melt down through the floor and into the ground beneath.
This has been called the China Syndrome.
During a meltdown, it is virtually certain that molten fuel will contact groundwater under the plant. Resulting steam explosions will spread radioactive fuel particles throughout a wide area.
Millions of people could be contaminated.
