Risk insights from seismic margin methodologies

The objective of this report is to discuss the current information on methodological aspects of obtaining risk insight from seismic margins methodologies. It is feasible in the context of a seismic margins review to gain an understanding of the risk significance of important seismic-induced accident sequences. These insights will be approximate and qualitative, and sometimes conservative in character. However, it is not feasible to obtain detailed characteristic of containment breach, timing, quantity of radioactive release or offsite consequences. 10 refs.
