3rd International Workshop on Measuring Techniques for Liquid Metal Flows (MTLM2015)

April 15-17, 2015, Dresden, Germany
(Supported by the Helmholtz-Alliance LIMTECH and the EU-project ESNII+)


Liquid metal cooling or liquid metal targets are relevant for innovative reactor concepts such as Fast Neutron Reactors cooled by sodium or lead and the spallation targets with lead-bismuth in a Transmutation System. Moreover, some instrumentation approaches are relevant for Gas Fast Reactors as well. The safe and reliable operation of liquid metal systems requires corresponding measuring systems and control units, both for the liquid metal single-phase flow as well as for bubble-laden liquid metal two-phase flows. Moreover, the availability of appropriate measuring techniques is an inevitable necessity for any experimental work on liquid metal technologies, for monitoring, controlling and optimizing industrial processes in metallurgy, casting, crystal growth, etc.

Measurements in opaque liquid metal flows still represent a challenging task as commercial measuring systems are not available for such fluids. Specific problems arise from the fluid properties, from high process temperatures of metallic melts, from corrosion and chemical reactions. Measurement techniques are needed to determine flow rates, flow velocities, heat fluxes, pressures, free surface levels, void fractions, dissolved gases, etc.

A session dedicated to GEN-4 Reactor instrumentation, for Sodium, Lead or Gas Fast Reactors will allow to address some specific needs such as core outlet measurements, fuel cladding detection, structure monitoring, etc.

The workshop is intended as a platform where new developments and different approaches in the field of measuring techniques and signal processing methods for liquid metal flows will be presented. The spectrum of measuring techniques is wide open, covering, for instance, local probes (such as electrical potential probes, optical probes, conductance probes, etc.), radiation techniques (X-Rays, Gamma-Ray attenuation, PET, neutron radiography), ultrasonic techniques, thermal and electromagnetic measurements.

A key issue is the applicability of the techniques to industrial relevant processes such as nuclear engineering, metallurgy, casting, solidification or crystal growth.

The goal of the workshop is to assess the state-of-the-art in the respective field, to identify the demand and requirements arising from various applications, to share knowledge with students and engineers recently involved in the respective fields, to stimulate the discussion between the involved teams, and to trigger new innovative developments or co-operations. We want to bring together developers of different kinds of flow diagnostics and potential users from industry, research institutes and universities.
