SUMMARY:InCoManD webinars on microbial activity | Predicting and Managing Microbial Activity in Deep Geological Repositories
DESCRIPTION: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 of a repository. \nThis session provides a structured introduction to microbiology in the DGR environment\, focusing on safety-relevant processes and their implications for engineered barrier systems. Selected experimental case studies from EPFL will illustrate how microbial activity is investigated under repository-relevant conditions\, with reference to the Swiss repository concept proposed by Nagra. Particular focus will be given to microbial activity during the transient phase\, including decreasing oxygen concentrations and spatial constraints caused by bentonite buffer swelling. \nThe session concludes with a brief overview of how experimental microbiological data can inform and constrain modelling approaches\, and how modelling can\, in turn\, support hypothesis testing and improve understanding of long-term microbial behaviour in DGR systems. \nLearning Outcomes \nUpon completion of this session\, participants should be able to: \nKnowledge \n\nDescribe the origin and potential activity of microorganisms in repository-relevant environments\nExplain key safety-relevant microbial processes\, including corrosion\, gas generation\, and mineral alteration\n\nSkills \n\nRelate experimental observations of microbial activity to repository safety functions\nIdentify critical parameters that control microbial activity in engineered barrier systems\n\n  \nPractical information\nClick here to register.

SUMMARY:EURAD-2 Webinar | Domain Insight 3.2.2\, on LL-ILW containers
DESCRIPTION:Abstract\nLow 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 various containers designs in order to condition the LL&ILW considering their physical and chemical properties. The main safety functions of a radioactive waste repository for Low Level and Intermediate Level Waste (LL-ILW) are the isolation\, the containment and the shielding of the waste. Other safety functions can also be considered\, such as the retardation of the radionuclide transport and maintaining stable conditions in the repository. The fulfillment of these safety functions relies amongst other on the Engineered Barrier System (EBS). During all the phases of the disposal programme\, from its initiation to the closure of the disposal facility\, safety assessments are performed and requirements are defined and updated in order to guarantee the safe management of the radioactive waste (during the operational and post-closure phases of the facility). The requirements for the design of LL-ILW containers are related to those for the disposal facility. The container requirements shall take into account the surrounding Systems Structures and Components (SSC’s)\, as well as the external and internal potential perturbations (e.g. physico-chemical reactions) which could affect them. Depending on the concept of the repository and the defined safety functions and objectives\, various materials such as concrete or steel can be used for manufacturing LL-ILW containers fulfilling the requirements. Such materials are currently used for the containers in various near surface LL-ILW disposal facilities currently in operation in countries such as France (CSA\, Aube)\, the UK (LLWR\, West Cumbria) and Spain (El Cabril\, Cordoba). It shall be noted that LL-ILW can also be disposed in deep geological repository (e.g. Switzerland) \nEURAD-2 – Domain Insight 3.2.2 – LL-ILW containers | Eurad  \nLearning outcomes\nUpon completion of this webinar\, participants should be able to: \n\nUnderstand LL-ILW waste and container design\nExplain the role of containers in:\n\nachieving operational & long-term safety of the disposal system\nachieving interim storage safety and feasible implementation of disposal\n\n\nProvide international examples of LL-ILW containers\nDescribe the lifecycle & implementation phases\nDiscuss challenges & innovations in container design\n\nSpeaker\nRadouane Sghir (Bel V) \nPractical information\nAn MS Teams link will be shared with all registrants a few days before the webinar.

SUMMARY:Online Training Sessions – Impact of Climate Change on Radioactive Waste Management
DESCRIPTION:Content\nWithin WP 11 CLIMATE Task 2\, two online training sessions on the impact of climate change on radioactive waste management will be organized on 19 and 20 May 2026\, from 9:00-13:00 CEST. Participants are strongly encouraged to attend both sessions (see below). Attending the first session is highly recommended to be able to understand the second session. Registrations\, free of charge\, can be done at the top of this page. Registrations will close on Thursday 7 May. \nDescription \nThe first session (Tuesday 19 May) is a general session. Through several lectures\, fundamental concepts related to the causes of climate change will be presented\, covering different time periods in the past as well as possible future developments. The session will also address how climate models and broader climate knowledge can be used in different ways to define future climate scenarios relevant for radioactive waste management. This includes both the construction and operational phases of disposal facilities\, as well as the very long-term post-closure phase. Particular attention will be given to the different sources of uncertainty and to approaches for taking these uncertainties into account. The session will conclude with the presentation of the climate add-on for the PEP serious game. \nThe second session (Wednesday 20 May) will focus in more detail on several specific processes that are strongly driven by climate change and whose assessment can contribute to a better understanding of the long-term safety of disposal facilities. This interactive session consists of three parts and is based on the development of specific case studies. \nThe first case study will address the impact of climate-driven changes in precipitation on the stability of engineered multi-layer covers used for near-surface disposal facilities. The second case study will examine the effects of climate change on groundwater flow and radionuclide transport\, both in shallow and deeper systems. The third case study will focus on the impact of climate change on landscape evolution over different temporal and spatial scales and its implications for safety. During this session\, exercises will be provided to help participants gain a better understanding of the timing\, amplitude and impact of the relevant processes and their uncertainties. \nTargeted audience and background knowledge \nAs the impact of climate change is relevant for all types of disposal systems\, across all relevant timeframes and in all possible climatic settings\, participation is open to all EURAD-2 partners\, including stakeholders\, end-users and representatives of civil society. \nThe required background knowledge is a basic understanding of the main components of different types of disposal facilities (surface\, near-surface\, shallow geological and deep geological). No specific prior knowledge related to climate science is required. It should be noted\, however\, that the second session on Wednesday will include several technically detailed sections. \nLearning outcomes \nAfter completing the sessions\, participants should be able to: \n\nDiscuss of the fundamental aspects of climate change\, its underlying causes\, and the uncertainties associated with it.\nTranslate outputs from climate models into climate scenarios\, and understand how to account for extreme events and uncertainties in this process.\nAssess the magnitude and timing of climate-related processes and their potential impact on radioactive waste management under different climates and climate scenarios\, including:\n\nthe stability of engineered multi-layer covers for near-surface disposal facilities\,\ngroundwater flow and radionuclide transport in both shallow and deep subsurface systems\,\nlandscape evolution at different spatial and temporal scales.\n\n\n\n  \nThe preliminary program is as follows: \nSESSION I – Tuesday 19 May: INTRODUCTION \n\n\n\nTime\nTitle\nPresenter\n\n\n09:00 – 13:00\nWelcome and Introduction\nLeonie Peti (BGE)\n\n\nClimate fundamentals and modelling at various scales\, and uncertainties associated with future climate predictions\nJohan Liakka (SKB)\n\n\nBreak\n–\n\n\nClimate scenarios and risks for construction and operational phases\nJin Park (VTT)\n\n\nClimate scenarios and risks for post-closure phase\nKoen Beerten (SCK CEN)\n\n\nPresentation of the climate add-on of the PEP game\nAlexis Geisler-Roblin (NTW)\n\n\nBrief summary and closure of day 1\nLeonie Peti (BGE)\n\n\n\n  \n  \nSESSION II – Wednesday 20 May: ADVANCED SESSION \n\n\n\nTime\nTitle\nPresenter\n\n\n09:00 – 13:00\nWelcome and Introduction\nLeonie Peti (BGE)\n\n\nClimate change impact on multi-layer covers: heavy rainfall and erosion\nOlivier Stab (Mines Paris)\n\n\nBreak\n–\n\n\nClimate change impact on groundwater flow dynamics and radionuclide transport\nÁlvaro Sainz (Amphos 21)\n\n\nClimate change impact on long-term landscape evolution at various spatial and temporal scales and implications for safety\nKoen Beerten (SCK CEN)\n\n\nClosure of the training session\nLeonie Peti (BGE)\n\n\n\n  \nPractical information\nRegistrants will receive a MS Teams link prior to the start of the sessions. If you opt to only attend the first session\, please inform us by sending an email to euradmobility@sckcen.be.
