This Lunch and Learn session will focus on: nuclear energy development in China policy for nuclear fuel cycle strategy for geological disposal of high level radioactive waste (HLW) in China Concept of area-specific (3rd generation) underground research laboratory for geological disposal of HLW site selection and site characterization of Beishan URL Design of Beishan URL excavation […]

In 2023 the European Parliament adopted a Pilot Project called a ’Proposal for a Joint European Approach towards Radioactive Waste’. The aim was to enable policymakers to assess, data in hand, whether pooling European resources together to deal with radioactive waste makes sense. DG ENER responded to the EP’s initiative by launching two parallel projects […]

Nagra has applied for a general license to establish a combined repository for high-level radioactive waste (HLW) and low to intermediate-level waste (L/ILW) in the geologically siting region of Nördlich Lägern in northern Switzerland. Leupin’s contribution presents the synthesis of the post-closure safety case, delineating how Nagra substantiate the long-term safety of the proposed repository. […]

We are glad to invite you to the Monitoring Equipment and Data Treatment for Safe Repository Operation and Staged Closure (MODATS) work package (WP) synthesis session. The MODATS WP of the EURAD aimed to evaluate, develop and describe monitoring methods and technologies, and to provide the means to measure, treat, analyse and manage monitoring data […]

Addressing uncertainties is an essential part of Safety Cases for geologic disposal facilities. An important instrument for doing so is sensitivity analysis (SA), by which the impact of input parameter uncertainties on the output(s) of model calculations is studied and evaluated. While some SA methods (such as linear and rank-based methods) are routinely applied in […]

All analytical results of an analysis come (or should come) with an uncertainty. This uncertainty, the “plus/minus number”, is often just taken for granted by the user of the results, without much further thought. In this talk, we shall explore in more detail what is hidden (or not) behind the uncertainty number of a destructive […]

The Lunch&Learn session organized by CORI is summarizing main information relevant in the context of this workpackage. Aim is to introduce (i) the basic scientific facts and concepts underlying this research focused on Cement-Organics-Cement-Interactions, (ii) explain the relevance of CORI in view of enhancing Safety, and (iii) present selected technical highlights from this EURAD activity. […]

Based on the huge volume of raw and processed information (here grouped as “knowledge”) to be handled in a national geological disposal programme, it is no longer a question of whether advanced KMS will be introduced into radwaste management programmes or not – only whether such systems can be developed and implemented before total collapse […]

In this talk, Virginie Solans will present the role of Artificial Neural Networks (ANNs) in a nuclear waste management context and explain how ANNs are reshaping conventional methods. ANNs are an example of machine learning, where typically large amounts of data are analysed. After a brief introduction to ANNs, she will provide examples of where […]
