As the focus of this book is on nuclear fuel reprocessing and nuclear-waste cleanup, we will focus on applications in these areas. This section will look at the reprocessing of nuclear fuel and the cleanup and segregation of nuclear waste with SRL and ANL contactors. Finally, other centrifugal contactors used for nuclear processing in France, Japan, Russia, and China will be discussed.

Patents on new module designs have been recently presented. Nitto Denko (Japan) patented a spiral wound design for membrane contactor applications [51]. The system includes a central feed pipe around which one or more membranes are wound. Tests on water ozonation demonstrated that it is possible to achieve a concentrahon of ozone 10% higher than in hollow hber. 

These findings are compared with extraction units already in operation in spent nuclear reprocessing plants. A summary of three solvent extraction contactors that are currently employed in recycling plants with throughput of 5 tonnes per year (e.g. THORP, SeUafield, UK UP3, Cap La Hague, France and the Rokkasho Reprocessing Plant, RRP, Rokkasho Mura, Japan) as found in literature (Nash and Lumetta 2011) is shown in Table 6.3.
