TEM analysis of Zirconium alloys using the “ChemiSTEM” Titan
Under certain operating conditions, zirconium alloys used as cladding material in nuclear reactors show accelerated growth behaviour induced by neutron irradiation. The occurrence of accelerated growth has been linked to the formation of c-component dislocation loops and an increase in solute concentration around second phase particles, but the mechanisms are still not fully understood. Improvements in analytical electron microscopes mean that smaller variations in the local composition can be determined and mapped with greater spatial resolution than previously possible. First results will be presented here of such high resolution EDX mapping on various zirconium alloys to show the capabilities of this technique regarding the study of irradiation damage.
