Decommissioning of fast reactors and other sodium bearing facilities is a domain in which considerable experience has been accumulated. This publication arises from an IAEA technical meeting convened to address decommissioning experience with fast reactors, in particular with regard to the decommissioning of components after sodium draining. Experience gained from the decommissioning of both active sodium loops and sodium cooled fast reactors was reviewed and analysed. The publication presents information on decommissioning and treatment process development, reactor and facility decommissioning experimental feedback, sodium cooled fast reactor waste characterization and treatment, and reactor decommissioning strategy.
