The Nuclear Corrosion Summer School (NuCoSS-19) has been held this week (July 7 – 12, 2019) and was a great success with 37 attendees (25 students and 12 scientists or engineers) and 12 lecturers from 15 countries, even from outside Europe (Canada, South Korea and USA). Also thanks to the perfect preparation by the local host (Slovenian National Building and Civil Engineering Institute – ZAG, Slovenia) it became a memorable event, not only from a technical/scientific point of view.
