The participants to the conceptual design review of ITER's cooling water systems.
The conceptual design review of ITER's component cooling water system, the chilled water system, and the heat rejection system was completed this week in Cadarache. The review was performed together with representatives from the Domestic Agencies in the US and in India, and experts from the international power producing industry of India and the ITER Organization. All three cooling systems will be supplied by the Indian Domestic Agency.
The component cooling water system (CCWS) will manage the heat rejected from the Tokamak cooling water system (TCWS), and the heat rejection system (HRS) rejects this heat to the atmosphere. The TCWS is used to remove the heat from the vacuum vessel and its internal components of the blanket and diverter. The chilled water system (CHWS) has two functions. One main function is to provide normal cooling to building HVAC units. Its other main function is to remove heat from safety-important components including heat removal from the vacuum vessel during loss of offsite power events using dedicated chiller package units that reject this heat directly to the atmosphere.
