How to Use Qualitative Analysis to Support a DSA
The use of judgement-based analyses that produces qualitative results can be a very effective method to demonstrate the safety posture of a nuclear facility. Such methodologies are recognized as appropriate through the graded approach established by the 10 CFR 830, Nuclear Safety Management and DOE-STD-3009. To successfully implement judgement-based analysis requires recognition of the uncertainties and biases that may be inherent with this approach. This paper will summarize the common errors that can occur when conducting judgement-based analyses and recommend techniques to improve the reproducibility and accuracy of such qualitative analyses. This paper will examine some of the Apparent and Not-So-Apparent Weaknesses associated with expert judgement and how to minimize these weaknesses. Examples related to the development of Documented Safety Analyses will be presented.
