Bounding Domains for Validation of Criticality Safety Calculations

摘要

Area of Applicability isrnsubdivided into Benchmark Applicabilityrn(BA) and Validation Applicability (VA).rnThe BA is the hyperspace formed by thernmultivariate set of benchmark parametersrnwith values that make a system orrnprocess critical. It is limited in scope byrnits restriction to a selected set ofrnbenchmarks. The more poorlyrncharacterized a benchmark experiment,rnthe larger a margin that will be needed.rnThe VA broadens the BA scope byrnaugmenting the specific benchmark datarnwith results from narrow interpolation,rnwide interpolation, and extrapolation, orrnwith results from other sources. Suchrnaugmentation comes with a price, whichrntakes the form of additional margins.rnSensitivity studies can be useful tornquantify these margins so that they arernsuitable for the system or process.
