Selection of our Projects

We work on around 450 projects every year. This involves a lot of knowledge, experience and team spirit.

We have compiled a selection of projects from our subject areas of reactor safety, decommissioning and dismantling, storage, disposal, safety, radiation protection and environment and energy, so that you can get an idea of what our work as a research and expert organisation looks like in concrete terms.

Geo-Dat
2011 - 2013

The aim of the integrated Geo-Dat project was to set up a thermodynamic database for the modelling of complex geochemical processes in deep geothermal layers of the North German Basin. Results from the integrated project are incorporated into the thermodynamic reference database THEREDA.

VIRTUS: Virtual underground laboratory as a new tool for repository research
2008 - 2014

Together with the Federal Institute for Geosciences and Natural Resources (BGR), DBE TECHNOLOGY GmbH, and the Fraunhofer Institute for Factory Operation and Automation (IFF), GRS has developed a new tool for repository research: the virtual underground laboratory VIRTUS.

2009 Konrad Transport Study
2007 - 2009

In its "2009 Konrad Transport Study", GRS examined and assessed the possible radiological effects of shipments of radioactive waste to the Konrad repository. The study concludes that these shipments do not result in any relevant radiological risk for man and the environment.

RepoTREND: Repository Safety Analysis
2007 - 2016

For a long-term assessment of the safety of final repositories for radioactive waste, the program package RepoTREND (Transport and REtention of Non-decaying and Decaying contaminants in a final REPOsitory) is being developed and applied by GRS. In this program package, all relevant processes which contribute to the mobilisation and release of contaminants from the repository, transport through the host rock and adjacent rock formations as well as exposure in the biosphere have been implemented.

THEREDA: Thermodynamic reference database
2006 - 2025

The main objective of THEREDA is the creation of a comprehensive, internally consistent thermodynamic reference database for geochemical modelling, with the work focusing on the special conditions in the near-field of a repository for radioactive waste in Germany.

Atmospheric Radionuclide Transport Model – ARTM
2004 - 2021

GRS has developed the atmospheric dispersion code ARTM on behalf of the Federal Ministry for the Environment and the Federal Office for Radiation Protection. ARTM simulates the dispersion of airborne radioactive substances and their deposition on the ground.

TOUGH2-GRS: Movement of groundwater, gases and radionuclides
1991 - Project ongoing

For repository search and design, it is important to have a good understanding of the geology of a possible site and the processes that take place in the host rock. In Germany, the three potential host rocks for disposal are salt, clay and crystalline rocks (e.g. granite). The term deep underground gives the impression of being rigid and inactive. Only a closer look reveals the diverse chemical, mechanical and hydraulic processes that play a role in the underground.

2024

Germany is currently looking for a site for a repository for about 27,000 cubic metres of highly radioactive waste. The future repository will be built in a geological formation of crystalline rock, salt rock, or clay rock. The radioactive materials are to be safely confined in the repository for one million years and retrievable for 500 years.

FENNECS: Simulating the neutron-physical behaviour of complex reactor cores
2024

Researchers worldwide are working on small modular reactors (SMR) and microreactors (very small modular reactor, vSMR). Many of these new reactor concepts are being developed for specific applications and have special core geometries. In order to be able to simulate the neutron-physical behaviour of these cores, GRS is developing the simulation code FENNECS (Finite ElemeNt NEutroniCS).

Reactor Safety
Storage
2024

Until a suitable repository is commissioned, radioactive waste will remain in interim storage. There are 15 storage facilities for high-level radioactive waste in Germany, including 12 decentralised storage facilities directly at the power plant sites and three centralised storage facilities at Ahaus, Gorleben and Lubmin.
