Opening of the Exhibition „Underground Research - World Wide“

Dr. Ingo Blechschmidt, Head of Grimsel Test Site:

Opening of the Exhibition „Underground Research - World Wide“

As already highlighted by the previous speakers, international cooperation is one of the major factors ensuring the ongoing success of the work at the Grimsel Test Site and at other underground research facilities. Not just by sharing resources but also by sharing expert knowledge while working together allows the development of outstanding projects and experiments which often run for many years.

Moreover, having a number of underground research laboratories operating around the globe helps to develop, test and demonstrate disposal concepts for radioactive waste under a variety of realistic boundary conditions in different geological environments. The contribution of the URLs and the focus of the activities depend on the stage of the national programmes, so each URL programme has its own special characteristics.

30 years of the Grimsel Test Site - its contribution to the realisation of deep geological repositories in Switzerland

Dr. Piet Zuidema, Head of Science & Technology, Nagra:

30 years of the Grimsel Test Site - its contribution to the realisation of deep geological repositories in Switzerland

Dear partners, dear guests, dear colleagues

I would like to welcome you all here to Nagra’s underground research laboratory - the “Grimsel Test Site” (GTS) at around 400 metres below the surface, high up in the Swiss Alps. This small ceremony is dedicated to the celebration of 30 years of research at Grimsel.

I would like to open the celebrations by highlighting the last decades of the successful research performed here and its contribution to our national repository programme and by addressing the very valuable and mutually beneficial role of our international partners, which is exemplified in a new permanent exhibition to be opened today.

Die Untertage-Forschung ist weltweit vernetzt

Von Andreas Staeger, Berner Zeitung.

Seit dreissig Jahren besteht an der Grimsel ein Felslabor, in dem die Grundlagen für die Lagerung radioaktiver Abfälle erforscht werden. Aus Anlass des Jubiläums ist dort eine Ausstellung eingerichtet worden.

Energiewende hin oder her – das Problem der Entsorgung radioaktiver Abfälle muss gelöst werden. Dieser Aufgabe widmet sich im Auftrag von Bund und Kernkraftwerksbetreibern die nationale Genossenschaft für die Lagerung radioaktiver Abfälle (Nagra). Seit 1984 betreibt sie im Grimselgebiet ein Felslabor. Die Anlage befindet sich nahe der Gerstenegg 400 Meter tief unter dem Juchlistock und liegt damit mitten im harten kristallinen Gestein des Aarmassivs. Sie ist über einen Zugangsstollen der Kraftwerke Oberhasli erschlossen.

USA DOE becomes a partner in Nagra’s GTS

Media Release : The Department of Energy of the USA (USDOE) has become a research partner in Nagra’s Grimsel Test Site, taking part in an international research project looking at the transport behaviour of radioactive substances in granite.

The scientific community in countries producing nuclear power, including Switzerland and the United States of America (USA), has come to recognise that deep geological disposal is the best option for safe, long-term management of high-level radioactive waste resulting from reactor operations. In 2009, the USDOE initiated a Used Fuel Disposition Campaign aimed at conducting research and development for generic repositories in various geological media, including crystalline rock. As a result of its interest in becoming more involved in international collaboration with ongoing R&D programmes, the USDOE decided to join the research programme at Nagra’s Grimsel Test Site. Organisations from eleven other countries are currently partners in the underground laboratory projects.

Press Release :

Testing a gas-permeable seal for deep geological repositories

Guttannen (Bern) – A multi-year, large-scale demonstration experiment has started at Nagra’s Grimsel Test Site, with the aim of confirming important aspects of the functioning of tunnel seals in future geological repositories. The experiment seal consists of a clay (bentonite)/sand mixture and will be used to demonstrate the feasibility of controlled gas transport from a radioactive waste repository on a realistic scale.

The GTS underground facilities are also available to interested 3rd parties for underground testing and research. The GTS offers cost-effective access to a fully developed, well characterised underground research facility with round the year logistical support - please contact Dr. Ingo Blechschmidt, Head of the Grimsel Test Site, for further details.
