Engineering design. (Safety aspect and plant design.)

Results of safety analyses and plant design conducted in the ITER Conceptual Design Phase are briefly reported. Safety analyses concluded that radiological doses from operational effluents and accidents are consistent with anticipated regulatory requirements. To improve safety further and meet the ambitious goal of “passive safety”, efforts are needed to reduce inventories of tritium and activation products. In the ITER plant design, no crucial problem is identified. The efforts in the Engineering Design Phase should be done for improving cost efficiency of the plant not jeopardizing safety features.
