SpinChem signed an agreement in 2019 with AtkinsRéalis for the exclusive use of their Rotating Bed Reactor (RBR) technology in nuclear environments, coined Spinionic™. AtkinsRéalis engaged with a client currently using an Advanced Liquid Processing System (ALPS) for water treatment. In this case, ALPS is unable to remove all contaminants, specifically iodine-129 (I-129). To verify that this effluent can be treated with RBR technology, pilot tests in 1 m3 containers were performed.
AtkinsRéalis and SpinChem are capable of deploying an RBR into either standard containers such as an IBC, or into non-standard containers with custom/modified deployment rigs.
SpinChem supplied an RBR as well as a deployment assembly. Factory acceptance tests were run with a standard IBC container. The assembly is clamped to the vessel, the RBR and driveshaft lowered with an appropriate lifting system.

This deployment rig was subsequently installed into a non-standard container on site, where site acceptance tests were performed prior to the operation of Spinionic™.

Tests were performed using multiple types of media (‘READ’, ‘AgZ’, ‘Kurare’) for different durations and effluent samples.

The tests were concluded successfully, and the results indicated excellent performance of the Spinionic RBR technology. Comparing test data to ALPS technology, conclusions about Spinionic™ include:
In short, Spinionic™ achieves a high processing rate, a high decontamination factor, and lower media consumption.
