N2 - Irradiation-induced changes of the atomic distributions of solute and impurity elements around carbides in a reactor pressure vessel steel of a Belgium nuclear power reactor were investigated by laser-assisted local electrode-type three-dimensional atom probe, before and after in-service irradiation of 12 years.

The atomic distributions of Mn, Cr and Mo inside the carbide indicate that their concentrations around the inner carbide–matrix interface were enhanced, while a clear segregation of P at the interface was observed.
