Progress in the Swiss national search for a nuclear waste repository

In September 2019 the Swiss National Cooperative for the Disposal of Radioactive Waste (NAGRA) commisioned Gesteinslabor with UCS, Brazilian and triaxial tests on neighbouring rocks of the Opalinus Clay - the rock which will host Switzerland's future facilities for nuclear waste disposal.

So far, stress-strain tests have been done on three different deep bore holes. The test results of the strength tests carried out at Gesteinslabor for the borehole Bülach and Trüllikon are now published on the NAGRA website: 

TBO Bülach-1-1: Data Report

TBO Trüllikon-1-1: Data Report

At the moment, Gesteinslabor is working on strength tests for the fourth deep borehole Bözberg.

Gesteinslabor receives funding from BMWi for the development of a new test rig. With this funding, our company will open up a new business field in renewable energies by implementing an innovative technology to determine the capillary threshold pressure with hydrogen on cap rock of underground gas storage facilities.
