The aim of this work is to assess the effect of neutral beams on the current version of ITER, principally in terms of the ability to ignite the plasma using neutral beam injection (NBI). The work makes use of the JET transport model by Taroni, Cherubini, Erba, Parail and Springmann. A feature of this model is that the transport in the whole of the plasma depends on the edge temperature and edge temperature gradient. The model is implemented in the JET version of the PRETOR code which is the vehicle for the present simulations. Using this new model, the route to ignition on ITER by NBI is explored. Various beam energies are considered and the plasma rotation resulting from the momentum input of the beams is described.
