Developement of the New Basic Correlation "MG-S" for CHF Prediction of the PWR Fuels

Year: 2024

Type: article

Abstract: It is important for core thermal-hydraulic design and plant safety analysis of PWR (Pressurized Water Reactor) to predict CHF (Critical Heat Flux) accurately. The accurate CHF prediction can enhance the reliability of the safety analysis and bring more efficient plant operations such as up-rating and higher burn-up fuel management. The new CHF correlation, MG-S (Mitsubishi Generalized correlation - for Standard grid), has been developed as a basic correlation of the new correlation series, which are for conventional and new-generation Mitsubishi fuel assemblies. Through comparisons with existing CHF data and a conventional CHF correlation, it was confirmed that MG-S can predict CHF with sufficient accuracy and extend its applicability to wider fluid parameters of interest.
