Abstract
Many existing containments in the United States have been shown to acc ommodate credible severe accident loads. Future containments should be explicitly designed for severe accident loads to reduce the uncertain ty associated with the response of containments to these low-probabili ty events. This paper examines the experiences from the application of current structural design codes for concrete containments, ultimate p ressure capacity evaluation of existing containments, and pressure fra gility testing of scale model concrete containments to arrive at the d irections for modification of national codes. Recommendations are prov ided to consider the severe accidents directly in the concrete contain ment design.
