Notes:
The irradiation induced defects of irradiated reactor pressure vessel(RPV) steel wereinvestigated by a small angle neutron scattering. The degradation of the mechanical properties of RPVsteels during an irradiation in a nuclear power plant is closely related to the irradiation induceddefects. The size of these defects is known to be a few nanometers, and the small angle neutronscattering technique is regarded as the best non destructive technique to characterize the nano sizedinhomogeneities in bulk samples. The RPV steel was irradiated in the HANARO reactor in KAERI.The small angle neutron scattering experiments were performed at SANS instrument in theHANARO reactor. Both unirradiated and irradiated RPV steels were measured and the SANS data ofboth steels were compared. The nano sized irradiation induced defects were quantitatively analyzedby SANS. The type of defects was also analyzed based on the SANS results, and the effect of thechemical composition of the RPV steel on the irradiation induced defects was discussed
