Integration Progress on ITER In-Cryostat Components

ITER overall Design Integration work is focused on processes to bring all different components together and to coordinate the interfaces. This is of special importance because the design maturity of the various systems is not always comparable which is causing some uncertainties and risks to the future development of the components. In 2010 the new ITER baseline was approved. Real physical interfaces were assessed under consideration of implemented changes coming from the ITER change process. Design Integration work was focused on resolution of identified clashes and providing design solutions on areas with high risk of interferences. Following examples will be discussed in the paper: - Cryostat integration; update of Cryostat components such as the top lid under consideration of assembly and welding procedures. In consequence related interface systems (e.g. Bioshield, Thermal Shield) were modified to meet space requirements. - Cooling Water System integration; a new In-Cryostat baseline design was developed by Design Integration in collaboration with CWS RO to accommodate new requirements from Blanket, Vacuum Vessel PHTS and Vacuum group. - Magnet Feeder integration; The ITER Magnet systems passed through their final design phase. The modified design caused interferences between adjacent components inside Cryostat. Clashes were identified with the help of Configuration Management Models, proposal were worked out to be compatible with assembly sequences and maintenance actions. The successful resolution of those integration items created an effective contribution to the preparation of the Cryostat and Magnet Feeder procurement arrangements which are signed or close to be signed. As the main In-Cryostat components are fixed more details on current missing items have to be shown, among them instrumentation lines, cable trays, Magnet structure cooling pipes and permanent platforms. The management of those space reservations inside the Cryostat will be introduced as a next step of the Integration approach.
