The peculiarities of the electron temperature profile under dominant on- and off-axisheating in the Rijnhuizen Tokamak Project (RTP) were successfully described by a `shell model'. This model features electron transport barriers that are associated with simple rational values of the safety factor. In the present work, this model is tested against JET data. To this end, the model is incorporated into the JETTO code, which is used to simulate JET optimized shear discharges with pronounced electron transport barriers. It is found that the model is successful in reproducing the time and location of barrier formation, as well as the subsequent evolution of barrier location and strength.
