Establishment of V&V procedure of numerical estimation method for thermal-hydraulic phenomena in sodium-cooled fast reactor, 1; Development of a least square version GCI estimation method (SLS-GCI) and uncertainty quantification

Tanaka, Masaaki  

In development of numerical simulation codes and estimation methods for plant design and safety assessment, implementation of verification and validation (V&V) and uncertainty quantification is required. To establish the practical procedures of the uncertainty quantification, the SLS-GCI (Simplified Least Square version GCI) method modified from the Eca's least-square version GCI method was established. Through the several examinations, the applicability of the SLS-GCI method was confirmed.
