SpinChem® signed a contract with AtkinsRéalis in 2019 for the exclusive use of their Spinionic™ Rotating Bed Reactor (RBR) technology in nuclear environments. Spinionic™ is ideal for in-situ deployment into vessels containing contaminated effluent, such as the caesium and cobalt removed in this case study using SpinChem® S14 RBR. The deployment rig was mounted to the main aperture at the top of the vessel and sat just 3 feet below the ceiling.
An effluent sample was taken from the vessel, and bench-scale tests were performed to identify the most suitable type and quantity of media.
bench-scale test results
CFD assessment performed by SpinChem® ensured the RBR generated continuous flow of solution throughout the vessel (no ‘deadspots’).

3D assembly model
The deployment rig lowered the driveshaft and frame down in segments due to the minimal head height above the aperture. A stainless steel drive system and an aluminum frame ensured durability in the highly corrosive environment.
deployment assembly
The deployment rig was mounted to the existing flange of the aperture at the top of the vessel, so no modification to the existing infrastructure was required.
in-situ deployment on the vessel
The deployment rig was manufactured in SNC Lavalin’s SP3 facility in Canada. Factory acceptance tests were virtually attended by engineers and team members from the UK, Canada, Sweden, and the USA.
