      abstract     = {Seeding of impurities into JET resulted in a pronounced
                      modification of plasma confinement properties. In order to
                      analyse the underlying mechanisms a predictive transport
                      modelling has been performed by means of two approaches. (i)
                      The Chalmers advanced fluid model for temperature gradient
                      driven instabilities is applied to determine all transport
                      coefficients necessary for transport modelling. In the
                      present code computations the radial profiles of the
                      particle densities and temperatures are computed using
                      experimentally measured sources. The computations give good
                      agreement of the temperature profiles with the measured
                      ones. (ii) The Julich transport model, used earlier to
                      simulate the plasma evolution in TEXTOR radiative improved
                      mode, has been amended by a proper description of trapped
                      electron transport, which is important at low collisionality
                      typical for JET. This model incorporated into the transport
                      code RITM, which self-consistently computes particle sources
                      due to plasma recycling and impurity ionization, reproduces
                      well the peaking in density and pressure profiles caused by
                      impurity seeding.},
