Grimsel Training Centre: Use of radioactive tracers in URL experiments (input to safety cases)

The Grimsel Test Site (GTS) is one of only a few URLs where radioactive tracers can be used in tracer migration tests in the geosphere at activities requiring a licence.  This course aims to show how such in-situ tests can produce results that are more reliable and realistic than standard in-situ tests using non-radioactive tracers.  The focus is on showing how results from laboratory based experiments, (the derived parameters of which are used as input to performance assessment calculations), are linked to field scale (1 – 10 m) in-situ tests, as well as improving process understanding of how radionuclides behave both in water conducting fault zones and in the rock matrix.
