Data for: Electronic model «FC-FNS» of the fusion neutron source DEMO-FNS fuel cycle and modeling hydrogen isotopes flows and inventories in fueling system

The key task of the fuel cycle (FC) design is to create a closed system providing the conditions for fusion burning in plasma, with reduce tritium inventory in the system elements. For this purpose “FC-FNS” electronic model has been actively developing as a tool for estimating fluxes of DT fuel and T inventories in systems where tritium is used. The paper describe the conceptual fuel cycle design for the DEMO-FNS facility and results of the modeling of hydrogen isotopes flows and inventories in fuel systems for steady-state operation mode.
