Abstract. In the disposal of radioactive waste in Germany, a question arises with regards to how confidence safety and thus also acceptability deep geological repository can be increased. One way achieve this is involve interested public monitoring process repository, even after emplacement phase already backfilled areas repository. The transdisciplinary research project TRANSENS, specifically ...

Abstract. Nuclear waste governance is a technical and societal task with numerous complex challenges. The goal generally accepted clearly defined, which that high-level to be stored in deep geological repository. path this determined by the site selection procedure outlined Repository Site Selection Act (StandAG). Today (2023), we are phase of moving from potentially suitable areas Germany limi...

Geologic disposal is a promising solution for safe permanent isolation of accumulated high-level nuclear waste from powerplants. The behavior host rock highly coupled thermally, hydromechanically, and chemically. Numerical simulations such phenomena the extremely long term (>100,000 years) large length scale (>1 km) geologic remain to be computationally challenging. In this study, methodology h...

Direct disposal of spent nuclear fuel (SNF) in deep geological formations is the preferred option for the final storage of nuclear waste in many countries. In order to assess to which extent radionuclides could be released to the environment, it is of great importance to understand how they are chemically bound in the waste matrix. This is particularly important for long-lived radionuclides suc...

The properties of (79)Se make it of likely potential importance in safety studies for geological disposal of radioactive wastes. Despite a substantial literature on toxic and nutritional aspects of selenium in the environment little consideration has been given to the behaviour of radioactive selenium and its potential transfer from a radioactive waste repository to the biosphere. Column experi...
