    Main benefits

    Pump performances in conformance with known S/C manufacturer expectations:

    • Flow rate (150 l/h)
    • Pressure rise (DPMAX = 1.5 bar)
    • Operating temperature (TQUALIF = +85 °C)
    • Operating with two-phase fluids (tolerant to bubbles)
    • Limited sub-cooling.

    Next steps

    • EM Pump Test (mid-2020)
    • Pump lifetime demonstration with EM model (began in 2020)
    • CDR Review and Qualification campaign (began in 2020)
