      abstract     = {Fusion reactor systems codes (SCs) are 0.5d codes used for
                      optimization studies towards the design of a tokamak
                      demonstration power plant (DEMO). These codes usually
                      comprise a description of the core plasma physics,
                      technology aspects and reactor economy, while only a coarse
                      description of plasma-wall interaction (PWI) aspects is
                      included. Therefore, the new systems code extension CELLSOR
                      (Code to Estimate the Lifetime Limited by Sputtering Of a
                      Reactor wall) was developed in order to allow inclusion of
                      PWI effects into reactor optimization studies. CELLSOR is
                      foreseen to be used as a secondary tool for PWI evaluations,
                      taking design point parameters from the European PROCESS
                      systems code as input. CELLSOR consists of an analytical
                      treatment of the plasma in the scrape-off layer (SOL) for
                      fuel ions (D, T), solving the 1.5d continuity equation in
                      fluid approximation to obtain perpendicular flux and ion
                      density in the SOL, and a fast Monte-Carlo description of
                      the neutral particle (D, T) behavior. The Monte Carlo (MC)
                      implementation of the new code extension was successfully
                      benchmarked with results from the EIRENE code. The
                      trajectories of eroded neutral W were computed within
                      CELLSOR ERO, an add-on code used for calculations of prompt
                      re-deposition and self-sputtering. The damage by ions was
                      calculated analytically for fuel (D, T), ash (He), seeding
                      gas (N) and wall material (W), including the acceleration by
                      a sheath in front of the wall, assuming radially constant
                      impurity concentrations.},
