Report on Tests Using a Flow Visualization Rig - Three Channel Per Pass Configuration

摘要

The flow visualization rig was upgraded to have 3 heated channels per pass. A series of natural circulation flow tests were done. Under test conditions, long periods of flow stagnation with high heater temperatures were observed in one of the channels. This 3 channel per pass rig shows flow patterns with some reverse channel flows, together with continued heat removal by the boiler. (Atomindex citation 16:078240)
