ASCE/SEI Standard 43, “Seismic Design Criteria for Structures, Systems, and Components in Nuclear Facilities,” is a consensus US national standard developed by the American Society of Civil Engineers. It provides design criteria for nuclear structures and should be used in conjunction with ASCE/SEI Standard 4 – “Seismic Analysis of Safety-Related Nuclear Structures”. The two standards are […]
Becht Nuclear Services recently applied ANSYS® multi-surface, with fluid-structure interaction (FSI) capabilities to evaluate the effects of seismic loading on vessel internals that are immersed in the fluid. Before proceeding with the analysis of the actual vessel, the FSI capabilities were benchmarked to an analytical solution of a simpler liquid-filled flexible tank under seismic loading. […]
Currently there are nearly 100 commercial nuclear power plants operating in the US with most of the plants commissioned between the mid 1960’s and the mid 1980’s. All plants are designed to be capable of safely withstanding a postulated earthquake, known as the safe shutdown earthquake. Similar requirements are imposed on US Department of Energy […]
