International audienceThe WEST project aims at transforming Tore Supra into an X-point divertor tokamak in order to adapt it to a unique relevant facility as test bed for ITER offering the key capability of testing the ITER technology of high flux components in real plasma environment. All equipment of the existing cooling loop B30 cannot ensure the cooling of the W divertor elements under ITER nominal conditions (12 m/s), so a new pressurized water loop must be designed to exhaust all the heat coming from the plasma and transmitted to the in-vessel components. It includes additional piping networks of around 50m3, replacement of the E30 exchanger and add of a P33 pump
