Even if the plant were destroyed, public health would not be jeopardized. As
proposed plants increased significantly in size after the mid-1960s, however,
experts began to worry that under some improbable but still plausible conditions,
a core melt could lead to a breach of containment. They postulated that, in the
event of a loss-of-coolant accident, the decay heat in newer, larger plants could
cause the containment structure to fail. The greatest worry was that fuel would
melt not only ...

in which the molten core would melt through the reactor vessel and then through
the floor of the containment building. Or, once the core melted, it might somehow
come in contact with water and set off a steam explosion powerful enough to
breach containment. A core melt would not inevitably lead to failure of
containment, for the containment building would withstand the effects of some
core melts, even in large plants. But the maximum credible accident might breach

type and characteristics of the containment system, type of stress, amount of
stress applied, intensity of stress, and duration of stress. . Predict the way in
which the containment system will breach. A breach is an opening (failure)
caused by damage to the containment system through which matter and/or
energy can or does escape. The types of breach include disintegration, runaway
linear cracking, closures that open up, punctures, and splits or tears.
Considerations include type and ...

A minimum figure of 0.7 m s-" breach velocity (inward velocity of air through a
breach) with a single glove removed, is widely used and is currently specified in
BS EN 12469. As the value of 0.7 m s” is arbitrary for one particular breach
condition, any additional requirements for containment or validation should be
agreed between customer and supplier. Lower breach velocities have been
successfully tested for containment. If such lower breach velocities are to be
specified, then the ...

spent fuel assemblies, incidents involving dropping of spent fuel assemblies, and
hoist failure accidents during the lowering of the waste container to the repository
can also cause breach of containment. Other repository operations involving
potential accidents in the handling of packaged spent fuel in steel containers
within a massive, shielded transfer cask are judged incapable of breaching

Other possible dangers of a core meltdown were that the molten fuel would
breach containment by reacting with water to cause a steam explosion or by
releasing elements that could combine to cause a chemical explosion. The
precise effects of a large core melt were uncertain, but it was clear that the results
of spewing radioactivity into the atmosphere could be disastrous. The ACRS and
the regulatory staff regarded the chances of such an accident as low; they
believed that it would ...

In this analysis, the researchers extended the decision tree in Figure 10-2 to
include additional chance nodes that include containment-building failure. The
probabilities and costs of the decision and chance nodes through vessel breach
are the same as in Figure 10-2. The additional chance nodes are described in
the following subsections. Vessel breach? The pressure in the reactor vessel at
the time of its breach influences the phenomena within the containment building
and the ...

The AEC had always sought to guard against such occurrences, but at the same
time it had recognized that the possibility of a major accident could not be
dismissed. Once it became apparent that under some circumstances the
containment building might not hold, the key to protecting the public from a large
release of radiation was to prevent accidents severe enough to threaten
containment from occurring. Reactor experts thought that a breach of
containment was most likely to ...
