For the Konrad mine the zoning approval for the construction of a repository has been available since 05.22.2002. By decree of 30.05.2007 the BMUB has instructed the BfS to carry out the conversion of the Konrad mine into a repository for radioactive waste with negligible heat generation.
The plans for the Konrad repository and the results of safety analyzes were summarized in the plan "radioactive waste repository Konrad Salzgitter" Konrad. By the end of the planning approval process, the state of science and technology (S & T) as well as the rules and regulations was (particularly the revision of the Radiation Protection Ordinance in 2001) considered regularly.
Based on the approval authority has established with the participation of experts in 2002 that the necessary financial security is ensured against damages resulting from the disposal of radioactive waste in accordance with the then current state of S & T.
As a responsible operator, the BfS sees a duty to a "review of the safety requirements of the Konrad repository according to the state of science and technology" (ÜsiKo) carried out before commissioning.
The BfS is based on high principles of transparency, accountability, openness and an independent review.
The ÜsiKo consists entirely of the following phases:
1. Determination of the verification needs;
2. If necessary, updating of Safety analyzes;
3. If necessary adaptation planning;
4. If necessary implementation under construction.
When ÜsiKo all safety analyzes for the Konrad repository are considered in the previous steps. This concerns the following aspects:
- long-term safety;
- accident analyzes;
- the intended operation;
- thermal influence of the host rock.
