      abstract     = {Effect of ELMs on fuel retention at the bulk W target of
                      JET ITER-Like Wall was studied with multi-scale
                      calculations. Plasma input parameters were taken from ELMy
                      H-mode plasma experiment. The energetic intra-ELM fuel
                      particles get implanted and create near-surface defects up
                      to depths of few tens of nm, which act as the main fuel
                      trapping sites during ELMs. Clustering of
                      implantation-induced vacancies were found to take place. The
                      incoming flux of inter-ELM plasma particles increases the
                      different filling levels of trapped fuel in defects. The
                      temperature increase of the W target during the pulse
                      increases the fuel detrapping rate. The inter-ELM fuel
                      particle flux refills the partially emptied trapping sites
                      and fills new sites. This leads to a competing effect on the
                      retention and release rates of the implanted particles. At
                      high temperatures the main retention appeared in larger
                      vacancy clusters due to increased clustering rate.},
