Serpent neutronics model of Wendelstein 7-X for 14.1 MeV neutrons
'Elsevier BV', 2021Co-Authors: Äkäslompolo Simppa, Koschinsky, Jan Paul, Kontula Joona, Bidermann Christoph, Bozhenkov Sergey, Kurki-suonio Taina, Leppänen Jaakko, Snicker Antti, Wolf Robert, Wurden GlenAbstract:In this work, a Serpent 2 neutronics model of the Wendelstein 7-X (W7-X) stellarator is prepared, and an response function for the Scintillating-Fibre neutron detector (SciFi) is calculated using the model. The neutronics model includes the simplified geometry for the key components of the stellarator itself as well as the torus hall. The objective of the model is to assess the 14.1 MeV neutron flux from deuteron-triton fusions in W7-X, where the neutrons are modelled only until they have slowed down to 1 MeV energy. The key messages of this article are: demonstration of unstructured mesh geometry usage for stellarators, W7-X in particular; technical documentation of the model and first insights in fast neutron behaviour in W7-X, especially related to the SciFi: the model indicates that the superconducting coils are the Strongest Scatterers and block neutrons from large parts of the plasma. The back-scattering from e.g. massive steel support structures is found to be small. The SciFi will detect neutrons from an extended plasma volume in contrast to having an effective line-of-sight.Comment: Proceedings of the SOFT2020 conference, to be sumbitted to Fusion Engineering and Desig
