Investigation of the melting of radioactive metallic KKN-plant components under controlled conditions
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 (< 60 Bq/g) steel components from the decommissioned nuclear power plant of Niederaichbach (KKN) were melted under controlled conditions in the period from June to November 1989. Co-60 and other ironlike nuclides remained, as expected, nearly completely in the ingot, whereas Cs-137 and Eu-152 concentrated in the slag. In spite of the short operation time, it was shown that a long-term operation of the melting plant would be possible without significant radiation exposure of the workforce. The main goal of the research contract, i.e. melting of 200 t of various higher contaminated steel wastes (200 Bq/g and 500 Bq/cm2) was not reached, due to the premature decommissioning of the melting plant by the KfK (for economic reasons).
