Fortum worked as the technology provider for delivering a radioactive wastewater treatment system to Grafenrheinfeld Nuclear Power Plant. The work was conducted in two distinct phases: system design phase and implementation phase.
In design phase the properties and requirements for the project in question were developed. Fortum’s patented NURES® technology, based on 100% inorganic, highly selective, granular ion exchange materials, is a modular and turn-key technology that can be used to clean multiple sources of radionuclides in radioactive liquid. In Grafenrheinfeld, CoTreat, SbTreat and CsTreat were utilized, alongside a prefiltering module to collect suspended solids in the liquid.
After finalizing design for the project, the NURES treatment plant was manufactured and designed in Finland after which it was installed and commissioned at the project site where it was used from 2020 until 2022 to treat the said radioactive wastewater.
