Description Even though the feasibility and safety of established container solutions has been demonstrated, recent progress in understanding of materials and processes has shown that optimisation of container manufacturing and performance is possible. Widespread interest in repository optimisation exists and relevant projects are ongoing, e.g., WP HITEC and the HotBENT experiment in Grimsel. The systematic […]

Management of knowledge, information and data can be a challenge in radioactive waste disposal and decommissioning. Planning, construction, operation and closure of a repository involves large volumes of information over an extended duration. At the same time information, data and knowledge about repositories must be accessible and understandable by numerous generations. Managing knowledge, archiving records […]

About the workshop During times of war, licensees of nuclear and radiation technology facilities may be unable to meet regulatory safety requirements designed for peacetime. This challenge has arisen in Ukraine, particularly within the radioactive waste and spent nuclear fuel management facilities located in the Chornobyl Exclusion Zone and units of the Chornobyl Nuclear Power […]

Introduction EURAD and PREDIS are organising a joint Summer School on Waste Acceptance Criteria (WAC) for radioactive waste. During this five day Summer School, participants will learn about the basics of WAC, WAC development and application, and examples of WAC in national programs. Theoretical lectures are complemented with excercises and two technical visits. Target audience […]

Background information Geomechanics plays a significant role in the understanding of the multiphysics and multiscale processes taking place in a geological disposal facility for radioactive waste. The objective of the training course is to introduce state-of-the-art understanding, concepts and methods related to thermo-hydro-mechanical coupled processes, the physical impacts of thermal loading and the mechanistic understanding […]

Abstract The presentation will be based on the State of Knowledge report for HLW/SF Containers (Domain 3.2.1).  Various aspects of container design and long-term performance will be covered in the talk, including: (i) safety functions, performance targets and container requirements, (ii) the factors underlying the choice of container material, (iii) a description of the nature […]

Training aims The main aim of the training is to address the training need “7.3.1 Treatment of uncertainty” identified in EURAD deliverable D13.1 as one the five most urgent and highest priority topics. The training will also address other urgent and high priority topics such as “7.1 Safety strategy”, “3.1 Confirm wasteform compositions, properties and […]

Background information The geochemical evolution of the near field barrier system of a geological disposal is important in view of the safety and performance analyses of the repository as it will influence (i) the durability of the different materials, and (ii) speciation and mobility of radionuclides. Given the time scales involved (ten thousand to hundred […]

During this online lecture, Kastriot Spahiu, the author of the Spent Fuel State-of-Knowledge (SoK) document, will discuss the SoK document, which focusses on the release of radionuclides from the spent fuel during disposal. He will focus on the highlights from the document and will dive deeper into issues related to spent fuel which are not […]

Background information EURAD WP13 in cooperation with NEA, IGD TP and SITEX.Network would like to invite you to participate in the EURAD Training Course on Safety Case Development and Review. Every national programme dealing with radioactive waste management is obliged to develop the safety case in relation to the radioactive waste facility and related licensing […]

Summary WP FUTURE is holding Education & Training Event on the scientific basis and safety relevant aspects of radionuclide transport and retention. The event could be of relevance to a broad audience of researchers, especially early carrier scientists, interested at better understanding the radionuclide retention mechanisms and their role in different disposal concept. Objectives Provide […]

HITEC deals with thermal impact and GAS concerns gas transfer, both in the context of geological disposal of radioactive waste. This school allowed the attendees to improve their understanding of heat transfers, water and gas migration, stress and strain evolution in a repository. The school addressed both experimental and numerical investigations, at small (lab) and […]
