The present workshop dealt both theoretically and experimentally with issues of primary damage and irradiation induced defect evolution, helium and other impurities, dislocation-defect interactions, deformation to large plastic strains and fracture. It was focused on the bcc structure (Fe, V and their alloys), but a number of presentations and discussions were centred around results in the fcc and hcp structures. (C) 2003 Elsevier B.V.
