Alternatives to on-site disassembly
Large components such as steam generators and reactor pressure vessels are not always disassembled on site but may be transported in their entirety for further processing or decay storage elsewhere.
For example, after initial decontamination, the steam generators from Stade nuclear power plant (KKS) were shipped to Sweden for further processing. There, they were dismantled, further decontaminated and melted down piece by piece. Most of the radioactive substances were then contained in the slag, so most of the steel could be reused. The residual radioactive waste, which only accounted for a small proportion of the total mass, was returned to Germany.
