Abstract

The safety study performed until December 2001 to assess the collective dose to the workers based on the International Thermonuclear Experimental Reactor (ITER) Fusion Energy Advanced Tokamak (FEAT) project, is presented in this work together with the relevant results. All systems located in the tokamak building of ITER FEAT facility important from the radiological point of view are considered. Radiological source terms with an important collective dose impact are airborne tritium and activated corrosion products (ACP) in the coolant of the water cooling system (WCS). A suitable computer code is used to assess the ACP inventory in the different WCS components. The dose rate is then assessed by considering walls attenuation with the 3D transport code MCNP, a Monte Carlo code that performs gamma ray transport calculation. Working activities needed to operate, maintain and replace each component of systems under study are partly provided by system designers and partly derived from the experience developed in operating nuclear fission reactors. In conclusion the collective dose result is shown and partly compared with that of previous ITER design stages considering the different systems and solutions and pointing out ALARA improvements. © 2002 Elsevier Science B.V.
