Going beyond – requirements for long-term strategies

TRANSENS Summerschool 2023

The school is thematically structured around a set of guiding questions on decision-making and the involvement of the different participants (stakeholders, science, public) in the field of nuclear waste disposal. We focus on the known-unknowns that have shown to emerge unexpectedly already in the past and can be expected to arise throughout the future processes of implementing disposal pathways in countries around the world.Each day will spotlight a specific topic of waste handling ranging from interim to final storage and their interdependences and interfaces, guided by the general questions How to handle unexpected developments: When to decide? Who to involve? Ensuring legitimization. Taking responsibility. Building trust in sustainable decisions.


The Summerschool takes place from Aug. 13th. to 20th. 2023 in Bad Honnef (Germany).

Lectures and workshops will be held by international experts in the field. The language of the Summerschool is english.
