perform calculations of pressure build-up in the cemented waste. However, due to the large number of factors involved in the calculation this is very difficult and cannot be successfully performed in every case. Fig. 144: Waste product cemented in lost concrete shielding without pressure relief Packages which cannot be verified must be re-conditioned in a laborious process. Substances relevant to water legislation Finally, consideration should be given to a topic of current interest – the declaration of “substances of relevance with respect to water legislation´”. This requirement, which has been taken over from legislation on conventional waste disposal sites, must be fulfilled for both newly conditioned waste and also for legacy waste. Fig. 145 shows an excerpt from the list of description and declaration thresholds for substances in accordance with List 1 of the Appendix to the Groundwater Directive [3]. Since a draft of the requirements to be fulfilled has only been available since October it is difficult to comment on the verification demanded. It does, however, seen apparent that in this case as well it will be more difficult to provide verification for packages that have already been produced than for those yet to be fabricated. As in the preparation of documentation described above, the main problem here will probably also is the quality of the old documents. In accordance with the draft of the repository conditions, no analysis of the waste product itself for verifying the substances of relevance for water legislation will be permitted. Verification will have to be provided by plausibility checks and analogous considerations. As with testing, application in practice will show how practicable this solution is. 205
Fig. 145: List of description and declaration thresholds [3] Results The fulfillment of the requirements for the repository KONRAD generates a challenge for a part of the legacy wastes. Because the requirements and enhancements of the repository conditions were late-specified, a part of the waste has to be treated again. This waste was conditioned in accordance to plans for the KONRAD repository. However, today much more stringent requirements have to be met for packages to be emplaced in KONRAD. Nevertheless the repository condition allows possibilities, to fulfil the requirements. References [1] B.-R.
