DIII-D water-cooling system upgrades through modeling and power saving projects
The DIII-D water-cooling system for the fusion facility at General Atomics consists of the vessel and coil cooling water systems (DIII-D water), components cooling water systems (power supplies, ion-sources, diagnostics and gyrotrons), and heat rejection system (cooling tower and heat exchanger) for the operation of the fusion facility. Since 2005 the water-cooling systems have undergone major upgrades, resulting in average power savings of over 50%. The water-cooling system is now capable of handling future heat loads for long pulse duration (10 s) while operating at lower cost.
