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

For the safe storage of zeolite wastes generated by treating radioactive saline water at the Fukushima Daiichi Nuclear Power Station, this study investigated the fundamental properties of the herschelite adsorbent and evaluated its adsorption vessel for hydrogen production and corrosion. The hydrogen produced by the herschelite sample is oxidized.

Summary written from the published abstract. It reproduces no proprietary data, methods, or results.

02 Why it matters

  • The back end of ion exchange: loaded media is itself a waste. This paper documents what a spent inorganic zeolite bed does in storage.
  • Hydrogen and corrosion: the two questions every waste-acceptance reviewer asks about a loaded vessel are answered with measured data.
  • Why inorganic media matter: the storage behaviour of inorganic zeolite is the reason Fluid Tech's ISM approach favours inorganic, vitrification-compatible media.
