[ RadSafe ] RE: Greenpeace nuclear video

[Graham, Christopher C.]

I have not yet had the pleasure of viewing the powerpoint, however,
Sizewell B is based on the US Wolf Creek and Callaway plant designs.
The containment building for these plants is 60 cm thick pre- stressed,
rebar- reinforced poured concrete with an inner steel liner.  It is
designed to withstand a direct hit from a 747 with no loss of
containment integrity.

I took a quick glance at the powerpoint by Dr. Large, famed consulting
engineer, and was amazed at the leaps of faith necessary to believe any
of
this.  Clearly Dr. Large either has an agenda or as a consulting
engineer,
needs to do a little more homework.  I won't bother the list with all
the
arguments about the validity of extrapolating low doses to significant
health effects, we all know that is unproven, controversial, and
probably
not correct.  However, the engineering aspects at the beginning of the
"presentation" are a bit surprising if he really is an engineer.  I
don't
know the Sizewell plant well but for US PWRs, the release of
radioactivity
necessary for the plume presented is pretty much impossible (engineers
never say never).  As are the "vulnerabilities" to an armed invasion by
insurgents.  Anyone interested should read some of the real science done
over the past few years on aircraft impacts to containment buildings to
learn what really might result - a big mess outside but no radiological
consequences.
