Description
In the framework of the EUROfusion DEMO Programme, the Programme Management Unit (PMU) is assuming the role of the plant and tokamak design integration. It is recognized, in part thanks to the ITER experience, that due to the large number of complex systems assembled into the tokamak vessel for integration it is of vital importance to address the in-vessel integration at an early stage in the design process. Furthermore in DEMO the auxiliary, heating, and fueling systems integrated in the tokamak will have to interface with and be integrated into a breeding blanket and will face a harsh nuclear environment during operation. The in-vessel components as a whole will have to satisfy the top level requirements of remote maintainability and high reliability; however for the engineering integration of single systems inside the vessel and breeding blanket, a deep understanding of the requirements of the interfacing systems is mandatory and has to be developed at an early stage in the design process.
In the EU DEMO design, after a first phase in which the different systems have been developed independently based on the baseline DEMO design defined by the PMU, an effort has been made here to define the interface requirements and to propose the integration strategies for the auxiliary, heating, and fueling systems into the vacuum vessel and the breeding blanket. This work presents the options studied, the engineering solutions proposed, and the issues highlighted for the in-vessel integration of the DEMO fueling lines, auxiliaries, heating systems, and diagnostics.
