Droplet Measurement Across a Grid Spacer in a 2x2 Rods During Reflood

  • 1. Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)

Description

Spacer grids are the essential structures used in nuclear fuel rod assemblies to maintain a constant distance between fuel rods. The droplet behavior across a spacer grid has received a great attention because droplets reduce significantly the temperature of fuel rods during the reflood in a postulated loss of coolant accident. The present study presents preliminary results for the droplet breakup during reflood. Measurements were made of droplets across a spacer grid in a rectangular channel with 2x2 electrically-heating rods. The sizes and velocities of droplets were measured by the help of image processing. The experimental data was statistically analyzed and compared with an existing correlation, in order to confirm the validity of the present experiment
