High Performance Cation Exchange Media

The Department of Energy’s Naval Marine Propulsion (NNL) is soliciting proposals for high‑performance cation‑exchange media that exceed the limitations of current mixed‑bed organic resins. Required characteristics include: (1) thermal stability sufficient for normal operating temperatures of ≥ 250 °F at saturation pressure; (2) a total mixed‑bed ion‑exchange capacity greater than 0.8 meq / mL; and (3) low solubility in dilute alkaline solutions at elevated temperatures. Offerors must describe the chemical or structural modifications to conventional organic resins—or propose entirely new materials—that satisfy these criteria. Selected candidates will undergo testing for cation‑exchange capacity, solubility, and physical integrity across a range of temperatures and exposure times. A Q&A session will be held over the next four weeks; interested parties should contact the point of entry (ATIP, at ATIP@unnpp.gov) to be included. The cognizant scientist is John Arnason and the cognizant manager is Cassandra Dickson. Proposals are due by 17 Mar 2026, 17:00 EST (notice NNL‑FMP‑0045).
