“…The maximal sodium inventory amounts to ~14 l, the mass flow rate specified is 300 kg/h and the maximal overpressure foreseen is 3.5 bar. Depending on the inner diameter of the test sample, sodium velocities up to ~5 m/s can be reached in the material probes [32].…”

The experimental liquid metal (LM) loops hosted within the Karlsruhe Sodium laboratory (KASOLA) com-prise a set of facilities to study Liquid Metal (LM) flows for various types of energy applications ranging from room temperature conditions used for education and training and fundamental research up to challenges posed by multi-physics problems such as material-fluid interactions at high temperatures. Extreme conditions, such as sodium boiling, relevant to thermo-electric conversion or fast reactor safety are covered in a dedicated facility small -scale (KARIFA). The complete experimental range is comple-mented by system code support and CFD simulation. The outcome is used for validation and develop-ment allowing application not only on component but also on system scale.

“…Also, new ideas are presented to extend the temperature range [1], [2] as well as proposals for dual systems including a topping system based on AMTEC [3]. The paper describes the safety oriented design as realized in the KASOLA facility [4] and gives hints for scale up to industrial size systems, especially for temperatures up to 900°C [5], [6] including different thermal energy storage options [7]. Options for fast return to operation in case of failures are under discussion, to reduce HTF caused outages.…”

“…Furthermore, the operational experience with sodium in the nuclear field and recently in small CSP facilities is extensive. To support the concept of a CSP power plant that uses sodium as HTF, several research topics have been identified that require thorough experimental and numerical investigations [3]. The major topics range between experimental investigations of fundamental thermal-dynamics in CSP relevant geometries, qualification of new materials based on creep-fatigue investigations and studies of corrosion and erosion, and development and tests of components (e.g.…”

“…flow sensors) for high temperature applications in CSP plants. Several high temperature sodium facilities have been erected at KIT to fulfill these tasks [3,4]. The lack of appropriate instrumentation for high temperature applications motivated the development at HZDR, Germany [5,6] and the experimental investigation at KIT, Germany of an innovative eddy current flow sensor.…”

Liquid metals, such as sodium, have been already successfully used as heat transfer fluids (HTF) in concentrating solar power (CSP) plants up to ~550 °C. Even higher temperatures can be achieved and are envisioned for future CSP plants. The lack of measuring flow rate devices at high temperatures for liquid metals motivated this study. The present paper presents the experimental mock-up and the experimental results obtained with the SOLTEC-2 facility for two test flow sensors, one innovative eddy current flow sensor (ECFM) developed at HZDR, Germany and a built-in permanent magnet fly-wheel sensor for runs up to a sodium temperature of 700 °C. The signals of the sensors are compared also against the power level of the sodium pump.
