The Indian portion of the cooling water system consists of three large subsystems—the component cooling water system, the chilled water system and the heat rejection system. The component cooling water system provides cooling water to various components of ITER, including the primary heat transfer system, at an inlet temperature of 28 °C. It transfers a total of ~1.2 GW of heat from these components to heat rejection system with a water flow rate up to ~8000 kg/s. The chilled water system will provide chilled water mainly for HVAC applications and also for cooling of some components with an inlet water temperature of 6oC and a total water flow rate of ~750kg/s. The heat rejection system is a system of large cooling towers—the final heat sink of the overall ITER plant, rejecting a total heat of up to 1.2 GW to the atmosphere.
