Behavior of a Nine-Rod Fuel Assembly during Power-Cooling-Mismatch Conditions - Results of Test PCM-5

摘要

This report presents the results of power-cooling-mismatch (PCM) Test PCM-5, an experiment designed to investigate the behavior of pressurized water reactor type fuel rods during postulated PCM accident conditions. The primary objective of the test was to subject a nine-rod fuel bundle to stable film boiling conditions to investigate the potiential for rod-to-rod interactions. In addition, the previously established PCM single-rod data base was assessed for multiple-rod geometries.
