Configuration management of the EU DEMO conceptual design data

Progress in the pre-conceptual CAD engineering of European DEMO divertor cassette

“…According to Systems Engineering (SE) principles [1], the divertor CAD model is reviewed, considering the updates in the DEMO configuration model presented by the Programme Management Unit (PMU) in 2017. The DEMO configuration management of CAD design data aims to support the concurrent engineering and to ensure consistency and robust working data as discussed in [2]. The conceptual design of the whole system, the design change and the interface requirements are mainly based on the initial definition of a DEMO baseline configuration model, released by PMU, containing the volume allocation and interfaces of the main sub-system [2].…”

“…The first divertor pre-conceptual design phase has been developed basing on the 2015 DEMO baseline model and the design activities have been described by authors in [3] [4]. Following the Design Change Request (DCR) procedure described in [2], in 2017 a change in the baseline DEMO configuration model has been implemented [5], mainly impacting the machine aspect ratio and providing a new volume allocation for the divertor cassette ( Fig. 1).…”

A New Interactive Railway Virtual Simulator for Testing Preventive Safety

“…Use of Virtual Reality (VR) in design has an important potential in addition to the others already well known in literature [1], [2]: it makes possible the analysis and the improvement of requirements and safety features of the product, by the user or by people demanded to maintain it during its life cycle [3], before it is physically realized [4]. Today VR is used in all fields of product design, where it is a fundamental tool to improve the safety in environments not always suitable for the human presence, such as transportation systems [5], multi-physics [6], [7] or fusion field [8]- [10], especially coupled with other well-known design methodologies, such as systems engineering [11], [12].…”
