BASE is responsible for providing public information about incidents, accidents or other events relevant to nuclear safety at the Morsleben repository, Konrad and the Asse II mine. BGE mbH is obliged to report such events to BASE. All since 2017 are published on the BASE website.

The reporting criteria in the Nuclear Safety Officer and Reporting Ordinance form the basis for this. There are three reporting categories : Category S - Immediate report (without delay), Category E - Urgent report (within 24 hours), Category N - Normal report (within 5 working days).

The operator appoints one or more persons in accordance with nuclear law. These persons shall be responsible for ensuring compliance with the obligations arising from the Atomic Energy Act, the Radiation Protection Ordinance and the licensing documents.

BASE approves the appointment of persons in charge according to nuclear law (Sections 9b para. 4, 7 para. 2 no. 1 AtG). The person responsible under nuclear law is the first point of contact for BASE on all questions relating to repository safety and compliance with the obligations arising from the licensing documents or legal provisions.

Furthermore, the person in charge according to the Federal Mining Act is another contact point for BASE regarding final disposal in mines.

BASE is in charge of monitoring the surroundings of the Morsleben repository and the Asse II mine. It has commissioned independent metrology bodies to do this.

• For the Morsleben repository, this is currently the Saxony-Anhalt State Office for Environmental Protection (LAU).
• For the Asse II mine, this is currently the "IAF - Radioökologie GmbH".

The measurements cover the radioactive substances released from a repository to the environment via waste water and sewage. The air, precipitation, surface water, drinking water, groundwater and soil in the vicinity of a repository, but also the vegetation, the rural food chain such as crops and meat products as well as milk and dairy products are also sampled metrologically.

As the operator, BGE mbH regularly takes samples of air, water, soil, vegetation, fruit, vegetables and milk, and compare its measurement results with those of BGE mbH. It assesses the radiation exposure as well as compliance with the maximum permissible activity discharges. The maximum permissible activity data and dose limits must be complied with. This is based on the Guideline for Emission and Immission Monitoring of Nuclear Facilities (REI).

In addition to the legally required measurements, an additional measurement programme in the interest of the citizens and local agriculture took place near the Asse II mine until 2017.

BASE will publish the measurement results it has commissioned:

Environmental monitoring reports

BASE issues clearance certificates (Section 31 StrlSchV): Radioactive materials and movable objects, buildings and ground surfaces that could be activated or contaminated may not exceed certain clearance values so as to be disposed of as waste.

The clearance values can be found in the Radiation Protection Ordinance. Clearance measurements are frequently carried out, especially in the Asse II mine. This is necessary because the water running from the surrounding rock into the salt dome is being removed on a continuing basis.

So-called modification procedures will be implemented in case of changes to the way facilities are built or operated. Changes that do not deviate significantly from the approved planning will be examined and subsequently approved by BASE.

An application must be submitted to the licensing authority for any major modification. In the case of the Konrad repository and the Asse II mine, the competent authority would be the Lower Saxony Ministry for the Environment, Energy and Climate Protection.

In the case of the Morsleben repository, it would be the Ministry for the Environment, Agriculture and Energy of Saxony-Anhalt.

BASE carries out inspections of the repositories, and makes sure that construction work complies with the permits and legal regulations (e.g. planning approval decisions). In addition, BASE inspects the facilities, systems, components and facility safety.

BASE will also carry out an overall inspection once every five years for the Morsleben repository, and once every ten years for the Konrad repository and the Asse II mine.

BASE may issue instructions to initiate protective measures or to temporarily cease operation (Section 19 para 3 of the Atomic Energy Act). This will occur,

• if the facilities do not meet the requirements of nuclear and radiation protection law, or
• if there is a risk that radioactivity will have negative consequences for life, health or property.

BASE must verify the reliability of all persons relevant to the safety of the repositories and the Asse II mine (Section 12b AtG; AtZüV (Atomrechtliche Zuverlässigkeitsüberprüfungsverordnung (Nuclear reliability review ordinance)). This includes, for example, an identity check, an enquiry with the police and the Office for the Protection of the Constitution, an enquiry with the Federal Commissioner for Stasi Records and with the Central Register of Foreigners/Aliens Authority. Depending on the activity and responsibility of the persons to be examined, BASE will carry out correspondingly extensive checks. Such an examination will only be carried out if the persons have given their prior written consent.
