Registration is now open!

We are delighted to announce that registration is now open for the IGD-TP’s international Symposium and Webinar on the role of optimisation in geological disposal programmes for radioactive waste.  Hosted by Nagra in January 2022, the event is open to anyone interested in geological disposal of radioactive waste.

Register for the Symposium, Webinar or both, and submit your poster application here.

Geological disposal projects are first of a kind projects, span several decades, and are multi-billion endeavours.  In order to build and operate repositories safely, to make consistent progress, and to ensure efficiency, optimisation of all aspects plays a critical role and is a continuous activity throughout its implementation.  While safety optimisation is well established, also through international guidelines, optimisation of the implementation of geological disposal has gained increased attention.  This symposium and webinar aim to summarise the status of the main aspects of repository optimisation from a technical-scientific viewpoint and to discuss future directions.

To enable access and involvement of all interested parties, the event will be held in two parts.  The first, physical event, will consist of a two-day meeting in Zurich with sessions on:

  • the role of optimisation in selected national geological disposal programmes
  • technology and material optimisation
  • lessons learned from optimisation in large infrastructure projects
  • integrating optimisation for safety
  • global optimisation approaches – concepts and numerical applications

A number of side events will also be arranged to make the most of attendee time.  Registration for such meetings will be arranged separately to the Symposium.

The third day will provide an opportunity for attendees to tour the Mont Terri underground research laboratory, the ZWILAG interim storage facility or a Nagra drill site as part of the ongoing exploration programme for the site selection process (see below for facility descriptions).  Tour numbers are limited.

The second part of the event will consist of a live webinar that will include a panel discussion and question and answer session.  Talks and posters presented at the Symposium will be recorded and made available online, prior to the webinar.  It will be possible to submit questions for the webinar panelists in advance on the IGD‑TP website and during the webinar.

Interested parties can attend the Symposium, the Webinar, or both events.

Call for Posters!

Throughout the Symposium the IGD-TP will host a series of themed poster sessions that aim to showcase the cutting-edge radioactive waste management RD&D of our community.  The posters will also be displayed on this website.  We strongly encourage you to submit poster applications that align to the IGD‑TP Strategic Research Agenda.

Poster applications can be submitted when registering here.
