As part of the second-phase testing at the HDR (Heißdampfreaktor) Test Facility high-level seismic experiments were performed on an in-plant piping system to study the response of piping subjected to seismic excitations. Various dynamic pipe support systems, ranging from very flexible to very stiff support configurations have been investigated. In general it was observed that the peak dynamic support loads, at least at some locations, were significantly higher than those predicted by the design calculations.
