RBI is focused on a systematic determination of relative risks 运 用 系 统 化 的 确<br />

定 相 对 风 险 . In this way, facilities, units, systems, equipment, or components<br />

can be ranked based on their relative risk.<br />

This serves to focus the risk management efforts on the higher ranked risks<br />

and allow decisions to be made on the usefulness of risk management efforts<br />

on lower ranked risks. If a quantitative RBI study is conducted rigorously and<br />

properly, the resultant risk number should be a fair approximation of the actual<br />

risk of loss of containment due to deterioration.<br />

Numeric relative risk values determined in qualitative and semi-quantitative<br />

assessments using appropriate sensitivity analysis methods also may be used<br />

effectively to evaluate risk acceptance.<br />
