D7.9 Mobility of staff

Mobility of students staff is a key issue in the project The strong focus on modelling activities and of the assembling and reuse of existing data in the project gives good opportunities for this kind of activities and partners are strongly encouraged to undertake exchanges within the Beacon programme Most of the partners within the project are ready to receive staff from the other partners In particular where synergies are identified by the crosscutting theme coordinator exchanges of students and staff are encouraged The target is to enable personnel to gain experience of working in different cultures types of organisations and gain appreciation of other scientific aspects of the project This forms an important aspect of the professional development offering to the Beacon project partners The key target group for the staff exchange is PhD students involved in the project at the different European universities The following staff exchanges are already planned by the partnersVTT Finland and LEI Lithuania will each visit the partner institute for at least two weeks within WP5 to couple expertise and training of junior researchers or PhD students in COMSOL modelling work ICL will host visiting lectures from Beacon partners which are open to students staff and general civil engineering industry to crossfertilise ideas and future collaboration This is relevant for all working WPsICL also have tradition and experience of hosting visiting PhD students academics or postdocs who wish to use their experimental and computational facilities to conduct some aspects of their research This is foreseen to be offered as a training possibility and mobility measure in Beacon This is relevant for all working WPs

The outcome of the this work package is planned to be a hydromechanical assessment of the case studies given a range of uncertainties in the boundary conditions based on empirical and numerical evidence that based on a probabilistic approach would ultimately result in a set of requirements under consideration of the host rock and the repository design For this work package three case studies were defined the ANDRA tunnel plug the Nagra disposal cell and the KBS3 deposition tunnel backfill

D7.5 Training Course

The Beacon project will arrange one specific training course during the project, within WP7. The course is envisaged to take place at Universitat Politècnica de Catalunya (Spain). It will take place very early in the project to maximize the impact. The duration is expected to be ~3 days. The topics of the course will be: 1. The issues around the mechanical evolution of bentonite in nuclear waste management 2. The fundamental science behind the mechanical properties of bentonite 3. Current conceptual and mathematical approaches 4. Hands on training with a computer code The main focus will be on 2), 3) and 4) above. The course will be directed toward the waste management community as well as students in areas of soil science, mechanical engineering, etc. The course will be arranged in collaboration of at least three of the academic institutions that are involved in the project.
