Optimisation of loading Konrad-containers with nuclear waste arising from the decommissioning of a MOX-facility

During decommissioning of the Siemens MOX facility in Hanau plutonium contaminated waste with a high content of fissionable material are accumulated. Main contributions to these solid wastes are plastics and metals from the decommissioning of glove boxes. The conditioning methods of the individual waste streams for disposal are qualified on a campaign-by-campaign basis. The responsibility for the approval of the applied conditioning method is with the German Bundesamt fuer Strahlenschutz (BfS). An essential part of the waste qualification process is the evidence that the activity as the quantity of fissile material respectively fulfil the repository's demands on the acceptable amount of fissile material. For waste minimisation it is essential to exploit the marginal values of the waste acceptance criteria of the repository. At the same time it is necessary by minimize the steps to be taken during conditioning due to health physics aspects. For this reason different measurement devices are applied during decommissioning of the Hanau Mox plant. (orig.)
