Current information on the surface infrastructure

In the ongoing Stage 3 of the site selection process for a deep geological repository, Nagra is concretising the surface infrastructure in collaboration with the potential siting regions.

A deep geological repository for radioactive waste also consists of facilities at or close to the surface. This "surface infrastructure" is required for the construction and operation of the repository. More detailed information is available here.

How is the surface infrastructure concretised together with the regions?

With a view to the upcoming general licence applications, in Stage 3 Nagra is concretising the surface infrastructure in the three remaining siting regions Jura Ost, Nördlich Lägern and Zürich Nordost in collaboration with the regions. In May 2019, Nagra published site-specific proposals for the surface infrastructure that serve as a basis for discussions. Information on this collaboration is available here.

The provisional statements of the regional conferences on Nagra's proposals are announced for the spring of 2020. By mid-2020, Nagra will compile a report on the advantages and disadvantages of placing the encapsulation plants outside the siting regions. This will form the basis for the following transregional collaboration. Affected regions, Cantons and neighbouring German districts will participate in these discussions.

Following this, the definitive responses of the regional conferences on the concretisation of the surface infrastructure are expected for the spring of 2021. These form an important point of reference for Nagra as to where and how to plan the surface infrastructure in the regions. The approximate location and size of the most important elements of the surface infrastructure will be submitted together with the general licence application.

The blue text-box to the right lists information sources for the surface infrastructure, including a brochure containing the most important facts on the surface infrastructure as well as factsheets that provide an overview of Nagra's proposals and work reports containing detailed information on these proposals.
