The project aims to develop understanding of the generation and release of C-14 from radioactive waste materials under conditions of underground geological repositories. KIT-INE contributes with experimental studies to work packages “Steels” and “Zircaloy” as well as to the work package “Dissemination of knowledge”. Within the two experimental work packages, KIT-INE conducts studies with highly active stainless steel and Zircaloy-4 samples in the shielded box-line of KIT-INE.
