ABSTRACT

Safety analysis for nuclear facilities are performed in a conservative manner so that there is additional assurance that the nuclear facilities are safe to operate given the potential events that may impact or challenge the facilities. The degree of conservatism included in the analysis should be well know and be increased if there is a large degree of uncertainty associated with the analysis. If uncertainty is decreased, through better data or more sophisticated and/or rigorous analysis, a decrease in conservatism can be made without impacting the margin of safety of the design.
