“…Clearly, the model curves in figure 1 a are approximations and additional three-dimensional neutronics calculations are required to provide a more accurate dependence on A . As a cross-check, it is noted that the R = 2.7, A = 3.5 fusion development facility (FDF) [24,25] with copper magnets requires a 25 cm thick inboard DCLL blanket to achieve TBR ≥ 1. This implies a 73 cm inboard WC shield plus blanket total thickness is required to achieve a 60 cm WC-only shield equivalent, whereas figure 1 a indicates 78 cm at A = 3.5.…”

Compact tokamak fusion reactors using advanced high-temperature superconducting magnets for the toroidal field coils have received considerable recent attention due to the promise of more compact devices and more economical fusion energy development. Facilities with combined fusion nuclear science and Pilot Plant missions to provide both the nuclear environment needed to develop fusion materials and components while also potentially achieving sufficient fusion performance to generate modest net electrical power are considered. The performance of the tokamak fusion system is assessed using a range of core physics and toroidal field magnet performance constraints to better understand which parameters most strongly influence the achievable fusion performance.This article is part of a discussion meeting issue ‘Fusion energy using tokamaks: can development be accelerated?’.

“…3D neutronics analysis has been performed [36] to assess the compatibility of the baseline design of FNSF-AT with neutron damage, and evaluate the tritium-breeding ratio (TBR). The FNSF should have breeding blankets that produce adequate tritium to cover its need as well as generate the required startup inventory for the DEMO.…”

Physics based integrated modelling of the baseline scenario for a Fusion Nuclear Science Facility based on the Advanced Tokamak concept (FNSF-AT) (Chan et al 2010 Fusion Sci. Technol. 57 66) has found steady-state equilibria with good stability and controllability properties at the fusion performance required to accomplish FNSF's nuclear science mission with margin. 2D divertor analysis for this baseline scenario predicts that peak heat flux <10 MW m−2 can be obtained even with scrape-off layer power width ∼1 mm. Using this baseline fusion performance, high fidelity and high-resolution 3D neutronics calculations show acceptable cumulative end-of-life organic insulator dose levels in all the device coils, and TBR >1. Two current drive scenarios, two divertor configurations, and two blanket concepts have been analysed. FNSF-AT would complement ITER in addressing science and technology gaps to a commercially attractive DEMO, and could enable a DEMO construction decision triggered by the achievement of Q = 10 in ITER.
