For the Japanese JT60-SA reactor, the goal is to absorb peak powers of about 12 kW with average cooling power over a 6 kW plasma cycle. HELIOS operates with forced convection of supercritical helium at 4.4 K and 5 bar pressure.
We realized the design of the loop and subcontracted the realization. Cold setting, circulation of the cryogenic fluid, calibrations and obtaining the nominal operating conditions have been successfully tested. The test campaign with pulsed loads starts in October.
