Corrosion of nuclear materials, i.e. the interaction between these materials and their environments, is a major issue for plant safety as well as for operation and economic competitiveness. Understanding these corrosion mechanisms, the systems and materials they affect, and the methods to accurately measure their incidence is of critical importance to the nuclear industry. Combining assessment techniques and analytical models into this understanding allows operators to predict the service life of corrosion-affected nuclear plant and storage canister materials, and to apply the most appropriate maintenance and mitigation options to ensure safe and economic long-term operation and waste storage.


The summer school will cover all necessary topics, starting with fundamental electrochemistry, to provide a self-consistent understanding of nuclear corrosion issues. Internationally renowned experts (e.g., F. Scenini, D. Engelberg, R. Kilian, H.P. Seifert, P. Efsing, J. Noël, S. Ritter, L. Martinelli, J. Macák) will give lectures on the following topics (the programme will be available at a later stage):

  • Electrochemistry and corrosion (incl. hands-on experiments)
  • Overview on corrosion in the nuclear cycle
  • Corrosion in light water reactor plants (incl. monitoring & mitigation aspects and a focus on environmentally-assisted cracking)
  • Corrosion in nuclear waste disposals
  • Corrosion in Gen IV systems
  • Case studies and ageing management
  • Advanced technologies to characterize corrosion

Target audience

The summer school is primarily intended for people from nuclear authorities, industry and research organizations/universities who would like to get a comprehensive overview on the field of nuclear corrosion.

Between lectures – have some (networking) fun!

The schedule consists of morning and evening lecture sessions with plenty of free time in between, intended for networking and organized sport & leisure activities.


The summer school will take place in Hotel Špik, in the beautiful alpine area of Slovenia (close to Kranjska Gora). The Hotel is situated about 60 km (45 min by car) from the International Airport Ljubljana (see map below).

Špik, Alpine Resort, Slovenia
