                      components in the DEMO scrape-off layer (SOL) with a
                      divertor is reworked to describe limiter discharge phases.
                      It provides radial profiles of the plasma density and
                      temperatures of electrons and ions, averaged over flux
                      surfaces, which are calculated self-consistently at the edge
                      of the confined region and in the SOL, without prescribing
                      any decay lengths at the last closed flux surface. It is
                      assumed that on the limiter discharge phase in question the
                      plasma will be in the L-mode of the energy confinement and
                      the radial transport in the SOL is modeled with coefficients
                      of the Bohm type. Computations give the plasma particle
                      flows both to the limiters and to the first wall (FW). This
                      allows us to assess the erosion rates by plasma ions of
                      these reactor components. In the case of the FW physical
                      sputtering with hot atoms generated in charge-exchange
                      collisions of ions with neutral species, recycling from the
                      wall and limiters is also taken into account.},
