Armin Roth

Armin Roth, born in 1959, received his engineering diploma (“Dipl.-Ing.”) in materials science from the Friedrich-Alexander-Universität of Erlangen-Nürnberg, Germany, in 1986. His major subject was corrosion & surface technology, supported by in-depth studies in general properties of materials and physical chemistry. For five years he worked as a research scientist at the Institute for “Corrosion and Surface Technology” of the same university. During this period, he performed a major governmentally funded research project on corrosion of Aluminium-Lithium alloys for aircraft structures. He received his PhD in corrosion engineering from the same university in 1991. 

Since then, he has worked in the department of “Materials, Corrosion and Welding” for Siemens AG / Power Generation Group (KWU), followed by Siemens Nuclear Power GmbH, Framatome ANP GmbH, AREVA NP GmbH, AREVA GmbH, and most recently for Framatome GmbH. 

From 1996 to 2003 he was section leader of the mechanical materials testing section within this department. Since 2003, he concentrates his expertise on the performance of technical and scientific engineering projects as well as on consultancy in direct contact with customers from plants and utilities. 

Armin Roth has gained a broad experience in scientific investigations and interpretations as well as the application of scientific knowledge for the engineering assessment of mechanical components of nuclear power plants such as reactor pressure vessels of boiling water reactors (BWR) and pressurized water reactors (PWR) pipes, pumps and valves. In particular, he was consulting for various root cause analyses of failed parts, for projects of component replacement or refurbishment of the installed base of Siemens/KWU design plants, and for Framatome’s new build EPR projects of Olkiluoto 3, Flamanville 3, and Hinkley Point C.

His knowledge and experience comprise general corrosion, uniform and localised corrosion, environmentally assisted cracking (EAC) including stress corrosion cracking (SCC), irradiation assisted stress corrosion cracking (IASCC), strain-induced corrosion cracking (SICC), and corrosion fatigue (CF) respectively environmentally assisted fatigue (EAF), according to the more recently applied terminology. His main materials of concern are all kind of steels, i.e. carbon steel, low-alloy steel, stainless ferritic and ferritic-martensitic chromium steels, and austenitic stainless chromium-nickel steels. He has also basic knowledge in corrosion and EAC of Ni-alloys, Cu-alloys, Al-alloys, Ti-alloys. Moreover, he has worked with ageing mechanisms of metallic materials in general and has authored a catalogue of ageing mechanisms for mechanical components in nuclear power plants with light water reactors.

From a project perspective, he represented the company in several national and international projects and working groups. In particular, since 2000 he serves as a member of the board of directors of the International Cooperative Group on Environmentally Assisted Cracking (ICG-EAC), a non-profit organisation of experts registered in the USA. He was appointed chairman of this group in the period from 2019 to 2022. Furthermore, for more than 10 years he served as working group leader of the “low-alloy steel”-section of this scientific and engineering group. 

He was awarded the level of Chief Advisor by Framatome GmbH and Fellow Expert by the Framatome Group. Furthermore, he received the title of Fellow by the EdF group.

His work is documented in the international public domain in more than 50 scientific publications at conferences and in scientific journals. 

Since January 2025 he has entered the state of retirement.
