In the current design of the international thermonuclear experimental reactor (ITER) cooling system heat exchangers (HX), the primary water flows in the shell side of the component and the secondary water in the tube bundle and the channel head. The reason behind this design is the need to reduce the collective dose to the operators working inside the HX channel head. To evaluate the effectiveness of the design, the radiological dose accumulated by all the personnel involved in the different working activities connected with the HX operation was assessed. The collective dose was calculated using a procedure applied to assess the occupational radiation exposure since the end of the ITER conceptual design phase.
