The melting plant for radioactive waste metals, EIRAM, is located in the premises of the decommissioned research reactor FR2 at the Kernforschungszentrum Karlsruhe. About 250 t of low radioactive steel components from the decommissioned nuclear power plant of Niederaichbach (KKN) were melted in a controlled area from June to November 1989. Co-60 and other iron-like nuclides remained, as expected, almost entirely in the ingot, whereas Cs-137 and Eu-152 concentrated in the slag. In spite of the short operation time, it was shown that long-term operation of the melting plant would be possible without significant radiation exposure of the workforce. The main goal of the research, the melting of 200 t of various higher contaminated steel wastes (200 Bq/g and 500 Bq/cm2) was not achieved due to the premature decommissioning of the melting plant by the KfK.
