Nuclear power plant components withstanding even the strongest earthquakes

The HDR Safety Program Project has entered the third phase. While the first phase, from 1975 to 1983, was concerned with experiments under normal operating conditions or conditions of an incident for the study of fluid-dynamic and thermodynamic processes and the behaviour of safety-relevant components, the second phase which was successfully concluded in 1988 was concerned with the causes and scenarios of accidents, quantification of safety margins of nuclear reactors, and the modelling of accidents. The third phase which started in the spring of 1988 is intended to yield insight into the long-term behaviour of components and will cover experiments for data acquisition for accident management.
