Abstract

Abstract

In this paper, the key issues in the development of reactor critical heat flux（CHF） correlation such as cold wall effect, non-uniform heating factor and statistical treatment of data have been studied, and based on the published CHF trial data we completed the localization of CHF correlation fitting and determination of the corresponding limit value. With a detailed statistical analysis of the calculation results, we established a rigorous method to determine the DNBR limits of CHF correlation.
