Achieving 95% Probability Level Using Best Estimate Codes and the Code Scaling, Applicability and Uncertainty (CSAU) (Code Scaling, Applicability and Uncertainty) Methodology.

摘要

Issue of a revised rule for loss of coolant accident/emergency core cooling system (LOCA/ECCS) analysis of light water reactors will allow the use of best estimate (BE) computer codes in safety analysis, with uncertainty analysis. This paper describes a systematic methodology, CSAU (Code Scaling, Applicability and Uncertainty), which will provide uncertainty bounds in a cost effective, auditable, rational and practical manner. 8 figs., 2 tabs.
