"Evaluation of fuelling requirements for core density and divertor heat load control in non-stationary phases of the ITER DT 15 MA baseline scenario"

F. Koechl R. Ambrosino P. Belo M. Cavinato G. Corrigan L. Garzotti D. Harting A. Kukushkin A. Loarte M. Mattei E. Militello-Asp V. Parail M. Romanelli G. Saibene R. Sartori

To ensure optimal plasma performance at high Qfus for the baseline scenario foreseen for the International Tokamak Experimental Reactor (ITER), fuelling requirements, in particular for non-stationary phases, need to be assessed by means of integrated modelling due to different expected fuelling behaviour and additional challenges that need to be…

"Integrated core-SOL modelling of fuelling, density control and divertor heat loads for the flat-top phase of the ITER H-mode D-T scenario"

L. Garzotti P. Belo G. Corrigan D. Harting F. Köchl A. Loarte E. Militello Asp V. Parail R.Ambrosino M. Cavinato M. Mattei M. Romanelli R. Sartori M. Valovič

The operation of a tokamak designed to test the sustainability of a thermonuclear grade plasma like the International Tokamak Experimental Reactor (ITER) presents several challenges. Among them is the necessity of fuelling the plasma to reach the density required to generate enough fusion power to achieve Q = 10 and, at the same time, to protect th…

"Modelling of Plasma Performance and Transient Density Behaviour in the H-mode access for ITER Gas Fuelled Scenarios"

M. Romanelli V. Parail P. da Silva Aresta Belo G. Corrigan L. Garzotti D. Harting F. Koechl E. Militello-Asp R. Ambrosino M. Cavinato A. Kukushkin A. Loarte M. Mattei R. Sartori

ITER operations require effective fuelling of the core plasma for conditions in which neutral dynamics through the scrape-off layer (SOL) is expected to affect significantly the efficiency of gas penetration. On the basis of previous analysis for stationary conditions, pellets are foreseen to provide core fuelling of high-Q DT scenarios. In this pa…
