Abstract Materials degrade in various ways: some corrode, some erode, some fracture. I will discuss our recent results on quantitative predictions for these phenomena. These results are obtained using Peridynamic (PD) models, which offer new ways to simulate complex problems by eliminating restricting assumptions inherent in classical models, like differentiability of the unknowns. I will […]

The host rock is the natural barrier that hosts the underground structure of the geological disposal facility (GDF). It  has a crucial contribution in either the isolation of the waste (crystalline rock) or the containment of radionuclides in the waste (clay and salt rocks). The host rock can be perturbed by the chemical and physical […]

About The presentation outlines the strategic role and planned research and development (R&D) program of the Radioactive Waste Management Plant (ZUOP), which is the sole operator of radioactive waste disposal facilities in Poland and is responsible for the management of radioactive waste and spent nuclear fuel. The program is closely aligned with the national policy […]

This talk will examine the role of microorganisms in deep geological repositories (DGRs) for nuclear waste. We will explore who these microbes are, how they survive in extreme environments, and how their activity affects the safety of the repository over thousands of years. Microbial Diversity: the key groups of bacteria, fungi, and archaea found in […]

Abstract Low and intermediate level waste (LL&ILW) represent the main part of the volume of radioactive waste which are produced by nuclear industry. This waste contains a large variety of materials such as paper, cardboard, plastics and metals with. The waste can also vary strongly in size and weight. Therefore, there is a need of […]

Deep geological repositories (DGRs) evolve through coupled thermal, hydraulic, mechanical, chemical, and biological processes. Within this multi-barrier system, microorganisms naturally present in host rocks — as well as those introduced during construction and operation — may induce corrosion, gas production, and mineral transformations, all of which are relevant for predicting the long-term performance and stability […]

Content The DI describes the concept of co-disposal - the final disposal of radioactive waste in different areas, and at the same or different depths in a single facility. It focuses on the interactions of materials used in the EBS in case of co-disposal and how to confirm that interactions between different EBS materials in […]

Join us for the EURAD-2 Webinar on Radioactive Waste Management (RWM) Infrastructures on Monday, 9 March 2026. Open to EURAD-2 partners and the wider RWM community, it will focus on the role of research and technical infrastructures in supporting RWM across Europe. It will also provide opportunity for stakeholder input and perspectives. This webinar is […]

About This Webinar Joëlle will explain where we are for the fusion energy development in the world and in EU. The technological gaps will be also presented with the associated R&D/industrial strategies to fulfill them.  A special focus will be given on the characterization of the radioactive wastes produced in a fusion reactor vs fission […]

About This Webinar Simon Morgan will explain the work of a nuclear safety regulator based on his time working in the Office for Nuclear Regulation (ONR) in the UK. He will also describe the role of the Western European Nuclear Regulators Association (WENRA) and in particular its Working Group on Waste & Decommissioning (WGWD) which […]

About This Webinar The Next Generation Network of the IGSC - building a platform for the next generation of safety case professionals S. Tillmann, A. Gehrke, H. El Fatihi, H. Javanmard, J. Rimando, S. Schiffmann The OECD Nuclear Energy Agency (NEA) Integration Group for the Safety Case (IGSC) was established in 2000 and works on […]

About This Webinar The NEA has launched several initiatives to advance understanding and solutions for the back end of innovative rector systems, including small modular reactors and Generation IV technologies, recognising this as a critical element for their responsible and sustainable deployment. A key effort in this area has been the Focus Group on the […]

Ireland is a small country with no historic or current civil or defence nuclear reactors or spent nuclear fuel storage or reprocessing activities. There is currently no centralised radioactive waste store. However, like all modern societies, Ireland uses radioactive materials in the form of sealed and unsealed sources in support of its high technology industries […]

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. […]
