Extensive Characterization of Novel Classes of Inorganic Ion Specific Media Designed for Highly Selective Removal of Salient Liquid Waste Radionuclides: Co, Cs, Sr, Ni and Tc

The characterization study behind a new class of inorganic ion-specific media, targeted at the five radionuclides that most often drive liquid-waste treatment: cobalt, cesium, strontium, nickel, and technetium.

Conference Paper

The scientist behind this work is Fluid Tech's Chief Technology Officer. Mark S. Denton led media technology at Kurion, Inc. during the Fukushima Daiichi response (the affiliation printed on the paper), and the isotope-specific media science documented here is the foundation of Fluid Tech's WTZ® and FHA products. The media and systems in this paper were Kurion's; Fluid Tech's current products are described under Ion Exchange Media. The summary below is for reference only; full details are in the cited paper.

01 Overview

Proper management of certain radionuclides is necessary for clean, safe, and secure radioactive-waste management at commercial nuclear power plants and DOE Environmental Management sites. Selective removal of specified isotopes through ion exchange is a proven treatment method. This paper extensively characterizes novel classes of inorganic ion-specific media developed for that purpose.

02 Why it matters

  • The five that matter: Co-58/60, Cs-137, Sr-90, Ni-63, and Tc-99 are the isotopes that set discharge limits and waste class.
  • Inorganic on purpose: inorganic media are leach-resistant, sluiceable, and compatible with vitrification.
  • The science behind FHA and WTZ®: selective inorganic media for cobalt, cesium and strontium is the approach Fluid Tech applied at Salem in 2023.
