Analysis of the results of thermophysical experiments with multi-rod bundles. Elaboration of the SCP thermalhydraulic test facility design

Abstract

The present report is devoted to the analysis of the thermophysical properties of supercritical water in the cores of supercritical water-cooled reactors (SCWR) and results of the experiments with multi-rod bundles cooled with supercritical fluid (mainly – water) flows carried out in different countries. The most important results and specific heat transfer regimes observed in the experiments were summarized. On the basis of the experimental data analysis the design of a thermophysical test facility for full-scale experiments for the determination of the heat and mass exchange regimes and supercritical water hydraulic parameters in multi-rod bundles was elaborated. The need for the experimental data for the proper description of the said processes was stated, and the importance of obtaining them was underlined. The list of the controlled parameters and experiments was created.
