Plugging Indicator - Measurement of Low Impurity Concentrations at a Constant Orifice Temperature

  • Damien Feron


Plugging indicators have been used extensively to measure impurity concentrations in liquid sodium systems. Simplicity of design, installation and operation is the most commonly quoted advantage. If there is no problem when the plugging temperature is important, it is more difficult to measure a plugging temperature when the impurity concentration is low. Then, the plugging temperature is often reported as inferior to 110 °C. This measurement is sufficient for the technicien. Sometimes, however, a more precise indication is required in cases where the implantation either an oxygenmeter or a hydrogenmeter is impossible. We propose a use for plugging indicator which satisfies this type of requirement.
