The special structural situations of nuclear power plant facilities also have to be
taken into account for the target accessibility considerations. In order to clarify the
relationships and to review the possible scenarios from the “bird's eye view,”
models of power plant facilities were manufactured among other thing. For exam-
ple it was examined whether it is possible to approach the unprotected regions of the
reactor building in realistic scenarios even with the encircling buildings. In the
areas of a containment with buildings in front the resulting impact force is consid-
erably reduced.
Figure
13.9
shows the reactor building of a convoy plant in a size comparison
with three aircraft models in a possible approach situation for clarification. It shows
that even with apparently advantageous terrain and buildings, an approach in the
scenarios above is still possible (Fig.
13.10
).
In summary with respect to the approach scenarios it is initially to be assumed
that it is possible for a large commercial aircraft to hit the reactor building in the
unprotected area in the case of a deliberate forced crash. A detailed examination
could be carried out for all sites.
