Thermoelectric power measurements: A non-destructive technique to evaluate ageing of reactor pressure vessel steels
The STEAM technique (Seebeck and Thomson Effect on Aged Materials), is a novel non-destructive method able to detect in a simple way degradation of materials, in particular to be applied on those steels that form the reactor pressure vessels of nuclear power plants. The STEAM method is based on the measurement of the thermoelectric voltage generated by the Seebeck and Thomson effects taking place in the material under test. The laboratory prototype device, designed and commissioned at the JRC-IAM, has demonstrated a high potential in materials damage evaluation. Within this study the capabilities of the STEAM technique to assess thermal ageing, irradiation embrittlement, and materials properties recovery after annealing treatments have been proved. In this paper the results of the application of the STEAM to irradiated material are shown.
