SOL modelling is a key requirement to design the next generation of burning plasma experiments. This is particularly true for Edge Localized Modes, because the energy released by an ELM in ITER could raise the target temperature above the tolerable limits. The simplest ELM models introduce ad-hoc transport multipliers. They should be carefully benchmarked against existing experimental data, before attempting any extrapolation to ITER. The ideal test case should be sufficiently well diagnosed to provide the input information required to define uniquely all the free parameters in the model, plus a set of additional measures to test the output. These are demanding conditions, often met only partially in practice. We illustrate the benchmark of the B2-solps5.0 code using an ELM from JET. In section 2 we describe the test case we choose, in section 3 we present our results and in section 4 we draw our conclusions.
