Description
The European Power Plant Physics and Technology (PPPT) programme, organised within the EUROfusion Consortium, aims at developing a conceptual design of a fusion power demonstration plant (DEMO) as a central element of the roadmap to the realisation of fusion energy.
Various integrated PPPT projects are being conducted to meet this goal including Breeder Blanket (BB), Safety and Environment (SAE), Magnets (MAG), Materials (MAT), Diagnostic and Control (DC), Divertor (DIV), and Remote Maintenance (RM). Neutronics plays an important role for all of the related activities since it has to provide essential data for the nuclear design of DEMO, assess and verify its performance. This requires, on one hand, the availability of suitable computational tools and data to ensure reliable neutronics simulations of DEMO, and, on the other hand, a coordinated approach for the variety of nuclear analyses performed within the PPPT projects.
Accordingly, the PPPT programme builds on a co-ordinated approach for DEMO neutronics including both development works on advanced computational tools and activities related to the nuclear design of DEMO and specific components. A dedicated “transversal” activity was implemented to co-ordinate the neutronics activities in an efficient way across the projects. The consistency of the analyses, e. g., is ensured by a methodological approach specified in guidelines for DEMO nuclear analyses. Development works on the improvement of nuclear data for DEMO are currently conducted in a complementary activity supported by F4E.
The paper presents in detail the outlined approach including the development works on advanced simulation tools and their application in PPPT nuclear analyses. The focus is on the methodological approach for DEMO nuclear analyses including blanket design, shielding, activation and radiation dose issues with the discussion of specific examples. In addition, the role of nuclear data for reliable DEMO neutronics design analyses and uncertainty assessments is addressed.
