Thanks to the Site Ion Exchange Plant at Sellafield, we can remove the majority of radioactive isotopes from water used in our nuclear operations, ensuring that any water we discharge into the sea is safe and well within permitted discharge limits.
What is the Site Ion Exchange Plant (SIXEP)?
SIXEP filters and removes radioactive isotopes – such as Caesium and Strontium – from water that’s been used in nuclear operations across the Sellafield site so that those isotopes aren’t discharged into the sea.
