In 2022 we have performed a project for the Federal Office for the safety of Nuclear Waste Management on the requirements for inventory models of radioactive waste (InvEnd), which we also presented at the Safe ND conference in Berlin in 2023. During this project we developed a model for determining such requirements, which we wrote in a paper.

We are happy to announce that our article on the conceptual model for determining inventory data requirements has been published in the Annals of Nuclear Energy.

The article presents a model that can be used by regulatory authorities and waste management organizations at various stages of the site selection process for the final disposal of all types of radioactive waste. It is based on the relevant national legislation, from which the inventory parameters required for conducting safety assessments are derived. Furthermore, it takes into account data uncertainties and conceptual inaccuracies of the evaluated data. Finally, it assesses the sensitivity of the defined safety-relevant parameters and the relevant factors, leading to a prioritization of the identified parameters. The model makes it possible to identify potential gaps and thus, address the optimization process.
