dc.description.abstract© 2022, Pleiades Publishing, Ltd.Abstract: As a result of self-consistent simulations using the ASTRA + SOLPS and FC-FNS codes, the range of parameters was found, within which the required fraction of tritium in the core plasma, fcoreT = 0.5, can be maintained by the injection of pellets with different isotope composition. For the DEMO-FNS tokamak, in the operating window of parameters, the interdependence of the fuel component fluxes used for plasma fueling is analyzed. The effects of the pellet injection from the high-magnetic-field and low-magnetic-field sides, used for the core plasma fueling and stimulating ELMs, on the fluxes in the DEMO-FNS fuel cycle systems are considered. It is shown that in the regimes with driven, convective ELMs, it is necessary to increase by one order of magnitude the capacities of the systems for pellet injection and separation of hydrogen isotopes, as compared to the estimates made previously without taking ELMs into account. The dependence of the frequency of the fuel pellet injection from the high-field side on their size and the particle confinement time in the plasma is found. It is shown that in the operating window of parameters found, it is necessary to inject pellets from the low-field side to stimulate ELMs. It is demonstrated that the additional stimulation of ELMs affects the requirements for the core plasma fueling.
