We are pleased to invite you to participate in our second
DFN Modelling Workshop Nuclear Waste Repositories - Stuck Between a Rock and a Hard Place?
The workshop is hosted by The Chair of Repository Safety (ELS) and Geological Survey of Finland (GTK) from 9th – 12th of June 2026 in Uppsala, Sweden at Ångströmslaboratoriet. While the main workshop will be held 9th to 11th of June, an excursion to Forsmark, the Swedish deep geological repository site in crystalline fractured rock, is scheduled for 12th of June. The excursion is optional and, like the workshop, free of cost. However, spaces for the excursion are limited, so please sign up early to secure your spot.
Objectives
The workshop brings together experts in discrete fracture network (DFN) modelling to explore and discuss free and open-source software solutions for nuclear waste repositories in fractured rock. The software to be demonstrated will include OpenGeoSys and porepy, and the number of software will continue to be updated here as registration starts. The objectives are to:
- Showcase and critically evaluate existing open-source software tools through presentations and hands-on demos/hackathons
- Foster exchange and collaboration on DFN-modelling approaches and challenges across geological settings
- Develop recommendations for modelling approaches in nuclear waste disposal
Preliminary structure
- Day One: Expert presentations from participants addressing current challenges and advancements in DFN modelling (10:00 - 17:00)
- Day Two: Hands-on demos/hackathon sessions of free and open-source software to learn about functionalities and possible use cases (10:00 - 17:00)
- Day Three: Presentations and demos alongside gathering of collective recommendations for future research collaboration and modelling considerations for nuclear waste disposal (10:00 - 13:00)
- Day Four: Optional excursion to Forsmark (08:00 - 16:00)
Logistics & Costs
- Participants are expected to cover their own travel and accommodation costs.
- We strongly encourage participants to bring their own laptops to both present their own software/projects and test software discussed during the workshop.
- See https://www.uu.se/en/campus/angstrom-laboratory/visit-us for information about the venue.
Platform notes
Before the workshop, if you have submitted a presentation contribution, we would prefer if you uploaded presentation materials through the platform by creating an account at indico.global. Please note the "Protected" field. It determines if you presentation is publicly available to everyone, only for participants or only for the organizers. Guideline to only show for participants: Toggle on "Protected", then click "Registrants" and choose the "Registrations for ..." option.
For those holding demos/hackathons, we will contact you separately regarding how materials will be distributed to participants.
This site will continue to be actively updated until and after the workshop so please stay tuned. The timetable of presentations and demos along with their titles and abstracts will be published at the latest shortly after the call for contributions/abstracts has ended mid April.
Please do not hesitate to contact us about the workshop, any issues or about this platform! See contact emails on the left.
