In the workshop Optimising the safety case through transdisciplinary research?, we want to discuss how safety cases on the disposal path for high-level radioactive waste can be optimised in a transdisciplinary way. The workshop not only offers the opportunity to exchange ideas on topics concerning the safety case, such as the design of a digital safety case, but also to get experiences with transdisciplinary methods and tools first hand.

Peer reviews are conducted to improve the quality of scientific publications and can also be applied to the safety case. Research within the TRANSENS project suggests that extending the spectrum of reviewers and using transdisciplinary methods and tools in reviews not only opens perspectives to improve the quality, legitimacy, and acceptance of a safety case, but also increases the resilience of safety on the disposal pathway.

Using case examples, insights and experiences from a complex conceptualisation and application process and two years research experience in the TRANSENS project will be presented taking the views of the involved (standing Working Group Population and scientists). Particularly, the understanding of transdisciplinarity will be discussed given the varying definitions in literature.
