Abstract
Model experiments have been carried out to investigate the impact of molten
core material against the head of a reactor pressure vessel. Results without and
with the mitigation influence of different internal structures suffering strong
plastic deformation and fracture are presented. Scaling rules to convert the
results to full scale dimensions are introduced and validated. It is believed that
this way of solution may be applicable also to other liquid structure impact
problems.
1 Introduction
In some accident scenarios severe loading and damage are produced by liquid
structure impact processes. Examples are: birds hitting air plane structures (the
birds can be treated as a liquid); water impact against ship walls and off-shore
