International Co-operation

© iStockphoto.com/ philpell The political goal of the Federal Government laid down in the Atomic Energy Act - to put an end to the utilisation of nuclear energy in an orderly manner - provides restricted operating lives of the German nuclear power plants during which the highest international standards will have to be complied with. The scientific bases required are made available by a national governmental precautionary research that is independent of interests of the industry and their organisations.

The maximum possible degree of technical competence and the availability of advanced assessment methods continue to be absolutely necessary for a scientifically based safety assessment of nuclear installations according to the state of the art in science and technology. The maintenance of the technical competence required for it is also indispensable against the background of nuclear phase-out in order to maintain the high quality of the safety practice for the remaining operating lives of the nuclear power plants. Moreover, it is a prerequisite for an active participation in the further development of international safety requirements, as well as for enabling Germany to influence the further development of nuclear safety, and thus the safety level worldwide.

Therefore, it has to be ensured that Germany does not fall behind in the dynamic process of developments which takes place in the field of reactor safety internationally. For these reasons, the international co-operation, intensively promoted in Germany by the Federal Government since the beginning of the peaceful use of nuclear energy, is of special importance today.

The GRS Research Management Division assists the BMWi in the planning as regards contents and the technical co-ordination of its international co-operation activities.

OECD projects

In addition to the bilateral co-operation and exchange agreements on reactor safety research, the projects within the framework of the OECD-NEA (Nuclear Energy Agency) are to be mentioned in particular which have gained in importance in the last years. These projects bring together the interests of many countries in the solution of jointly identified safety issues in the efficient use of the experimental resources still available internationally by joint financing of the necessary investigations. Moreover, they render a scientific added value because experts from different countries jointly develop in detail the planning of the projects and their realisation as well as the interpretation of the results and their impacts on safety.

For each of the OECD projects, a contract is concluded by the participants which stipulates the work programme, the financial obligations of the participating countries, the regulations for the realisation of the project and the access to its results.

In general, half of the costs for OECD projects is borne by the country which provides the experimental facility. The remaining costs are shared among the participating OECD countries. The respective shares are calculated according to a special distribution key of the OECD-NEA.

The financial participation of Germany is realised in most of the cases as projects within the framework of project-sponsored reactor safety research of the BMWi. On behalf of the ministry, GRS assumes the tasks of the signatory of the international agreements. The GRS Research Management Division represents the interests of Germany in the board of management or steering committees of the projects. In projects with financial participation of the German industry, the industry is also represented in the steering committee of the project. Technical issues of these projects are discussed and specified in detail by a Programme Review Group (PRG), consisting of experts from the participating countries. The final results of the PRG are submitted to the steering committee for decision-making. Depending on the topic, PRGs consist of experts from GRS, research centres or universities or the German industry.
