Nuclear Corrosion

Stefan Ritter (Dipl.-Ing., Material Science and Engineering, Friedrich-Alexander University Erlangen-Nürnberg, Germany) did his masters/diploma at Siemens Power Generation (KWU) in Erlangen (Germany) and performed research on stress corrosion cracking of austenitic stainless steels at Framatome ANP in Erlangen thereafter. Since 2001 he has been employed by the Paul Scherrer Institute (Nuclear Energy and Safety Research Division, Laboratory for Nuclear Materials) as a research scientist in the field of plant ageing management. He is currently working on different national and international research projects related to EAC of light water reactor structural materials and to mitigation technologies (e.g., noble metal chemical addition/NobleChem or Zn addition) and is also involved in consulting for EPRI. In 2004 he was one of the founding members of the ECG-COMON (European Cooperative Group on Corrosion Monitoring of Nuclear Materials, www.ecg-comon.org) and is currently Webmaster of this group. In 2012 he became the Scientific Secretary of the ICG-EAC (International Cooperative Group on Environmentally-Assisted Cracking of Water Reactor Materials, www.icg-eac.org) and in 2016 he was elected as Chairman of the Nuclear Corrosion Working Party of the European Federation of Corrosion (EFC).
