Abstract

This R&D project showed that the melting of radioactive waste metal from the dismantling/refurbishing of nuclear installations is an acceptable way of recycling nuclear waste. This material can be used for the casting of qualified products such as type-A and type-B waste containers. The results of the melting facility TAURUS were used to build the industrial scale melting facility CARLA. Individual tests and long-term investigations of the facilities showed that the licensing conditions are respected and that the radiation exposure of workers is in the range of the admissible limit for non-exposed people. The activity distribution within the cast product is homogeneous, so that its activity can be measured exactly before it is sent back to the nuclear area. By melting waste copper, it is possible to respect the specific limits for unrestricted re-use, whereas for brass the limit for conditioned re-use in the industrial field was reached. Radioactive carbon can only be bound in the form of small graphite lamellas or nodules in the cast iron. During the research programme around 2000 Mg of waste steel was melted on an industrial scale and used for the production of shielding blocks and waste containers.
