Abstract

An intensive integrated modelling work of main scenarios of the new tokamak DTT (Divertor Tokamak Test facility) with the Single Null divertor configuration has been performed using first-principle quasi-linear transport models, in support to the design of the device and to the definition of its scientific work-programme. First results of this integrated modelling work on DTT (R0= 2.14 m, a= 0.65 m) are presented here along with outcome of the gyrokinetic simulations used to validate the reduced models in the DTT range of parameters. As a result of this work, the heating mix was defined, the size of device was increased to R0= 2.19 m and a= 0.70 m, the use of pellets for fuelling has been advised and reference profiles for diagnostic design, estimates of neutron yields and fast particle losses have become available.
