Abstract

The aim of this R&D program is to demonstrate for ITER the feasibility of an in-vessel remote handling inspection using a long reach, limited payload carrier (1 to 10 kg). This device is dedicated to close inspection processes of the Plasma Facing Components (PFCs). The work includes the design, manufacture and testing of an articulated device demonstrator called Articulated Inspection Arm (AIA).

Tests of a scale one mock up of a single module focused on its ability to withstand the most critical loads. The main results concern improvement in the design margin to enhance AIA performances under ITER Temperature and vacuum operational conditions. New AIA technologies, including components and materials have been qualified through outgassing tests at 230°C with success. An upgraded AIA single module has been designed and its manufacturing is launched. This prototype module will be tested on the CEA Cadarache test facility under real vacuum and baking temperature conditions. A feasibility study of a full AIA operation in Tore Supra was performed, taking into account ITER reference requirements. A scale one demonstration of the AIA under ITER relevant condition is feasible on Tore Supra and would give significant improvement in R&D results for ITER remote handling equipment. The test of the AIA demonstrator behaviour is foreseen in 2005 in real Tokamak conditions.

The paper presents the full robot concept, the results of the first test campaign, the AIA new design and its integration on Tore Supra.
