Abstract
SANS data are presented for as-irradiated, irradiated and annealed, and re-irradiated weld material from units 4, 2, and 1, respectively, of the decommissioned NPP Greifswald. The unirradiated reference condition is represented by a data scatter band obtained for several unirradiated weld materials of the same kind. The effects or irradiation, annealing and re-irradiation are worked out. Comparison of the SANS data with available atom probe data for the same material from unit 4 indicates an apparent discrepancy between both methods. Possible reasons are carefully discussed. The dominant reason is the overestimation of the Fe fraction in the irradiation-induced clusters by APT due to trajectory overlaps.
