N2 - The Strategic Research Agenda (SRA; https://www.ejp-eurad.eu/publications/eurad-sra) of the European Joint Programme on Radioactive Waste Management(EURAD; https://www.ejp-eurad.eu/) describes the scientific and technicaldomains and sub-domains and knowledge management needs of commoninterest between EURAD participant organizations. Theme number 7 isentitled “Performance assessment, safety case development and safetyanalyses.” A list of research and development priorities and activities ofcommon interest to be addressed within EURAD for theme 7 have been established. Amongst others, the Understanding and modelling of multi-physicalThermo-Hydro-Mechanical-Chemical coupled processes (THMC) occurring inradioactive waste disposal is a major and permanent issue to supportoptimization of design and safety case abstraction. To tackle this challenge aresearch work package entitled “DONUT: Development and improvement ofnumerical methods and tools for modelling coupled processes” has beenconducted within the EURAD join programming initiative. The purpose of thiswork package is to improve/develop methods or numerical tools in order to go astep further in development of (i) relevant, performant and cutting-edge numericalmethods that can easily be implemented in existing or new tools, in order to carryout high-performance computing to facilitate the study of highly coupledprocesses in large systems, (ii) numerical scale transition schemes for coupledprocesses, (iii) innovative numerical methods to carry out uncertainty and sensitivityanalyses. In this paper the work carried out within the DONUT work package is putin perspective regarding the existing concept and literature on the field. It does notpretend to be exhaustive but rather to put emphasis on particular issues tackledduring the project.
