dc.description.abstract The safety analysis of CANDU (CANada Deuterium Uranium) reactors includes postulated accident scenarios in which a steam-water mixture is to be present in the headers and the feeders (components of the CANDU heat-transport system). Knowledge of phase and liquid distribution in the headers and feeders is essential to predict behaviour of the reactor under LOCA conditions. In the present study, an experimental flow loop was designed and constructed to investigate the two-phase flow distribution in a simulated CANDU header-feeder system. The header in this experiment, made of a transparent material, was a scaled-down version of the one used in Kowalski and Krishnan (1987) using a scaling ratio of approximately 8.5:1. Experiments were conducted using air-water mixtures at room temperature and a nominal header pressure of 170.3 kPa (abs). The test matrix included one- and two-turret injection, two inlet water flow rates (15 and 30 kg/min) and four different air flow rates for each water flow rate, giving inlet qualities of 3%, 1.5%, 0.75% and 0.375%. The outlet flow rates of air and water were measured in all the feeders under the condition of equal pressure drop across the feeders. (Abstract shortened by UMI.) en_US
