Methodology for phenomenological code assessment with integral test data

The use of codes in the licensing process requires a rigorous validation that can be accomplished by means qualitative and quantitative assessment. In thermal hydraulics, this has to performed at different levels, from separate effects integral response plant design. Even though assessment is preferred, for complex phenomenology involving behaviour whole system approach difficult usually through expert judgement. present article, methodology proposed combines adequacy simulation experiments test facilities. method makes statistical quantification Best Estimate Plus Uncertainty calculations.
