Low and intermediate level radio active waste has been produced in Germany for several decades. While a part of the waste had been deposited in the Morleben repository and the Asse mine which have been operated for just a limited period of time, the major amount is conditioned and packaged in temporarily stored waste containers.
Those containers are designated for final disposal in the KONRAD repository being currently under construction and expected to start operation in 2022. As a consequence, an assessment of the waste container documentation and safety is strongly needed to receive an approval for the KONRAD repository. This requalification is challenging because those old containers have to meet the same safety requirements as new containers.
Federal approval of legacy waste containers for the Konrad repository - strategies and challenges
(2016)
The approval of an increasing number of legacy waste containers for the Konrad re-pository is expected in the next years. While well documented young legacy waste containers can rather easily be approved, the assessment is challenging for contain-ers which were manufactured some decades ago. All parties have to work closely together to find a specifically fitted strategy for such approvals. Thereby, rework of documents and requalification can be a promising approach. Details about three basic strategies have been shown to give a hint which options are available.
