Research interests - Dr. Soraia Barroso:

My research experience and expertise are in the areas of mechanical testing, thermal ageing, irradiation effects, empirical research on material degradation and characterisation and non-destructive testing (NDT). It includes the material testing aspects, application of reactor safety and surveillance programmes of nuclear power plants.

I have worked at and collaborated with various European and International organisations, workgroups and institutions such as the INSA National Institute of Applied Science (Institut National des Sciences Appliquées), Fraunhofer Institute for Nondestructive Testing IZFP, MTA-KFKI Atomic Energy Research (AEKI) Institute, Joint Research Centre (JRC) of European Commission (EC), the Institute for Energy (IE) and the International Atomic Energy Agency (IAEA).

My research interests lie in the performance testing and characterisation of aeronautical and nuclear metallic materials in high temperature and irradiated environments. Also my interest includes the development and application of NDT, Barkhausen noise and acoustic signal and the incorporation of these into healthy monitoring systems and structural integrity assessment. In mechanical testing I specialize in the use of fracture mechanics, miniaturised samples and Master Curve.

Presently, my research work focuses on the development of nano- and oxide-dispersed strengthened (NDS-ODS) steel for applications in advanced nuclear reactor concepts, generation VI and future fusion energy, including the characterisation of irradiated material, e.g. Barkhausen measurements.
