Abstract :
The thermal shield system of ITER plays the role of reducing heat loads transferred by thermal radiation and conduction from warm components to the components and structures that operate at 4.5 K. In the design of thermal shields, it is of importance to ensure that they maintain thermal loads within the specified design criteria. In the present work, a study is conducted on thermal analyses in order to confirm that the thermal shield design can accommodate the thermal loads during the plasma operation state and the baking state of the ITER vacuum vessel. Design of the cooling tube layout of a vacuum vessel thermal shield is followed based on the results of thermal analyses. It is demonstrated that the present results can be applied to the detailed design of the ITER thermal shield system.
