Abstract
The microstructural features present in reactor pressure vessel steels after low fluence neutron irradiation have been characterized by atom probe field-ion microscopy. Unlike the clusters and precipitates which have been reported in pressure vessel steels irradiated to intermediate and higher fluences, very diffuse solute-enriched atmospheres have been observed. Although copper is associated with a high proportion of these atmospheres, phosphorus appears to play a more dominant role in the formation of these features.
