DRESDYN - A new platform for sodium related thermohydraulic studies and measurement developments

The safe and reliable operation of liquid metal systems in innovative reactor concepts like sodium cooled fast breeder reactors or lead-bismuth targets in transmutation systems requires appropriate measuring systems and control units, both for the liquid metal single-phase flow as well as for gas bubble liquid metal two-phase flows. We report on the liquid sodium facility DRESDYN (DREsden Sodium facility for DYNamo and thermohydraulic studies), presently under construction, that will comprise experiments with geo- and astrophysical background as well as experiments for thermohydraulic studies and for the development and the test of measurement techniques for sodium flows.
