- Abstract
- It is readily recognized that a significant source of damage from earthquakes is due to interactions between structures and components, such as the fall of a masonry wall or a ceiling on equipment, or the impact of a vlave on a wall or structure. There are also other significant, while less intuitively evident, sources of seismic interaction damage, such as flooding, spraying, fires, or electrical shorts. The understanding of all these sources of interaction damage and their evaluation in the field can easily turn into a significant effort. Yet, it is the opinion of the Senior Seismic Review and Advisory panel (SSRAP) that the evaluation of interactions, in a commercial nuclear power plant, should account for about 10 to 20% of the seismic "walkdown" devoted to equipment seismic qualification. To this end, SSRAP recognizes the need for "exercising of considerable udgement and experience - so that the program remains cost effective".
