Abstract

For nearly thirty years, significant research has been performed at Sandia National Laboratories to improve the understanding of the response of nuclear power plant steel and concrete containment structures and their capacity to withstand accidents beyond their design basis and other extreme loads. This work has consisted of experimental programs and analytical studies to investigate the response and capacity of containment structures and components for a wide variety of loading conditions with a primary emphasis on internal overpressurization. This report summarizes the work that has been performed and the results of these efforts, and identifies common themes that have emerged. The most detailed information provided is of the research conducted at Sandia National Laboratories, sponsored by the Nuclear Regulatory Commission. But effort is made to also highlight work conducted by other research organizations throughout the world to put the Sandia/NRC research into context and to attempt to summarize the current practice for evaluating containments subjected to accident loads.
