Force-vs.-time curves determined in the Sandia experiments, from [

]
The shock load-vs.-time curve determined in the experiment is shown in
Fig.
7.10
. It shows the force-vs.-time curves measured (In the dashed smoothed
Japanese evaluation, more peaks were filtered out of the data determined experi-
mentally than in the GRS curve) [
39
].
Given the fact that the brief shock load peaks occurring in the Sandia experiment
were covered by the slightly longer curve of the smoothed RSK-LL shock load-vs.-
time relation, relatively good agreement was found between theory, experiment,
and the given shock load-vs.-time diagrams.
The demand to include load assumptions made for airplane crashes in the
construction of nuclear power plants in accordance with the RSK-guidelines [
10
]
in this strict form so far had existed only in Germany (one exception being the
Japanese reprocessing plant of Rokkasho-Mura). For the EPR, German-French
guidelines were elaborated which roughly correspond to the German
RSK-guidelines [
10
]. Consequently, the EPR has a wall thickness of the concrete
containment of two times 1.3 m (Chap.
3
).
