Resumo

In a burning plasma machine like International Thermonuclear Experimental Reactor (ITER), diagnostic integration has to face among others, problems arising from the activation and dust contamination. The high flux of gamma rays and neutrons induces a deterioration of some diagnostic components imposing a relatively high rate of maintenance. Therefore, the design has to minimise the amount of radiation on diagnostic components and detection systems as well as making them as radiation hard as possible. Also, reliable and standardised remote handling (RH) procedures have to be developed for maintenance in an activated and dusty environment. The equatorial port #7 and upper port #10 presently integrates ten diagnostic systems. They require different types of vacuum connections: (i) extension of the primary vacuum, (ii) extension of the secondary vacuum and (iii) no vacuum extension. This paper describes the solutions for the implementation as well as the maintenance activities for the specific diagnostics installed on these ports.
