[en] The Studsvik Melting Facility has been in operation for almost 30 years. Many turbines, heat exchangers and other retired components, pipes, structures has been treated in the facility during those years. Studsvik treats low level radioactive contaminated metallic scrap, slightly activated metallic scrap and large components from power reactors. The ambition of all projects is to minimize the waste volumes for final disposal and to maximize the amount of material that can be recycled. Another objective, respecting ALARA, is to keep dose exposition to the personnel at very low levels. The overall concept comprises the whole sequence of preparations from road and sea transports, the management of the metallic waste by segmentation, decontamination and sorting using specially devised tools and shielded treatment cell, to the decision criteria for recycling the metals, radiological analyses and conditioning of the residual waste into a final form suitable for customer-related disposal. The records shows that the amount of material possible for conditional clearance to open market after treatment is between 95 - 97 % on weight for falling metallic scrap. For large components there is a larger span and especially for heat exchangers. This paper describes Studsvik's technical concept and experience related to treatment of metals from the program for modernisation and power upgrade of the Swedish nuclear power plants. (authors)
