COMPARATIVE ANALYSIS OF TWO TABULAR METHODS FOR CALCULATING CRITICAL HEAT FLUXES IN ROD ASSEMBLIES

摘要

The purpose of this work is to draw conclusions, on the basis of a comparative statistical analysis, about the accuracy and reliability of two tabular methods for calculating the critical heat fluxes in fuel assemblies (method of [8, chapter 3] with the latest corrections and the method of [9]). Both methods use the latest international version of tables for tubes with substantially different corrections. It is concluded that there is a large discrepancy in the description of the experimental data and that the method of Canadian investigators need to be improved. 3 tables, 20 references.
