In addition to the usual radiation and conventional hazards present during the decommissioning of disused nuclear installations, the presence of residual sodium or the alloy sodium potassium used in primary, secondary and support systems in reactors using liquid metal as a coolant presents additional technical, safety and cost challenges for decommissioning. This results from the propensity of these materials to react exothermically with water and moisture in the air potentially resulting in toxic and explosive reactions. This publication discusses a variety of treatment methods to be considered when dismantling components that still contain residual quantities of sodium or sodium potassium, several of which were presented as contributed papers to the IAEA session during the 5th International Conference and Exhibition on Decommissioning Challenges, in Avignon, France, 711 April 2013. The publication provides a synthesis of information presented. |
