The course programme covers scientific topics of direct relevance to the physical, chemical and radiological phenomena occurring during progression of severe accidents in Water Cooled Reactors, including an overview of past events and advanced technologies designed to cope with such events.
The course aims at building a comprehensive understanding of the complex phenomena associated with progression of severe accidents in WCRs and their consequences. Knowledge transfer will be facilitated between the international expert lecturers and the young nuclear professional and engineer participants through discussions and hands-on learning, with the goal to gain a comprehensive understanding of the physical, chemical and radiological phenomena specific to severe accidents in WCRs. Relevant nuclear safety principles, recent advancements in scientific methods, approaches and simulation tools to assess the interrelated phenomena during different phases of severe accident progression, and the role of technologies designed to prevent progression of, and mitigate consequences from, such accidents in WCRs will be presented.
Prerequisites:
As part of the application, participants should submit a 2-page original essay, covering two of the course topics of their choice from the topic Phenomenology in Severe Accident Progression.
