5B354 - PFR Ion Exchange Columns
The Sodium Disposal Plant (SDP) was used to dispose of bulk sodium from the PFR primary and secondary circuits. Initially sodium was reacted with water to produce NaOH that was treated with HCl to produce NaCl. The caesium removal plant removed radioactive contaminants from the brine by passing the solution through ion exchange columns. Ion Exchange Columns will also be used for cleaning of PFR pond water and for cleaning the effluent discharge from sodium cleaning operations within the Size Reduction Facility (PFRSRF).
