Eddy current flowmeters at core outlet in french sodium fast reactors

Abstract

Eddy current flowmeter (ECFM) is envisaged to measure sodium velocity at core outlet in sodium fast reactors. Firstly, sodium tests in a pipe were carried out to ensure the feasibility of this detecting principle. The sensor exhibited a good behaviour the flow rate dependence of its response is linear and a particular frequency exists for which the ECFM's normalized response is temperature independent. Moreover, a numerical modelling was developed with COMSOL to assess the efficiency of the measurement in an opened flow, i.e. without a pipe confining the flow. Despite the decrease of sensitivity, the signal keeps linearity. However, the frequency for which the signal is temperature independent has vanished.
