Overview of EPRI research in structural integrity

This paper is an overview of the structural integrity research within the Nuclear Safety and Analysis Department of the Electric Power Research Institute. This research addresses structurally related safety issues in light water reactors. Five major technical areas are covered: Analysis/Design Methods, Seismic/Vibratory Response, Fluid/Structure Response, Impact/Impulse Response, and Structure/Component Performance. Each technical area is briefly described and research results are highlighted. This paper puts in perspective the research and development work described in this special issue of the journal in addressing such safety and licensing issues as soil-structure interaction, seismic response of piping systems, hydrodynamic loads in pipes and vessels, pipe rupture and whip, jet impingement, missile impact, and concrete containment integrity.
