Tasks
As an internal staff unit of the Federal Office for Radiation Protection (BfS), the Repository Surveillance unit (EÜ) controls the operational procedures relevant under nuclear and radiation protection law in the Morsleben repository for radioactive waste (ERAM) in Saxony-Anhalt, the Konrad repository in Lower Saxony currently under construction and, since 1 January 2009, the Asse repository which is also located in Lower Saxony. Thus it is ensured that the repositories are operated in compliance with the legal and technical requirements. The Repository Surveillance unit is thus also a key component of the BfS-internal quality management. This also includes, apart from the supervision of the necessary measures concerning the erection, operation and decommissioning of these repositories, inspecting measurements in the vicinity of these installations and checking the reliability of the management companies' and contracting firms' staff in terms of the spectrum of tasks.

Examination of Monitoring Measurements
|
|
|
In the vicinity of a repository monitoring measurements of, among others, air, water, and agricultural produce must be carried out. The measurement results of the repository operator are examined by the Repository Surveillance unit (EÜ). Additionally, the EÜ gives order for carrying out independent measurements and compares the results with those gained by the operator.

Issuing of directives
|
|
|
If a repository does not comply with the legal requirements or in case of a hazardous situation, the Repository Surveillance unit (EÜ) can issue directives. Thus, the EÜ can, for example, arrange for certain safety precautions carried out by the operator. Normally, the repository operator himself proposes necessary safety precautions which are then approved by EÜ.

Technical Independence
|
|
|
The repository Surveillance unit (EÜ) performs its tasks in a professionally independent way. For this purpose it has extensive authorities. The EÜ is one of the BfS sections and is not subject to directives. The technical independence of the repository operator BfS has been ensured through the internal rules of procedure and own financial resources. The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) has the technical and legal supervision of disposal and of the Repository Surveillance unit (EÜ).
