“…Processing characteristics can be obtained from small-scale column testing with actual tank waste. From the column testing, the transfer zone, 50% Cs breakthrough, and overall process volumes to maintain the desired decontamination factor can be assessed (Nash et al 2006;Fiskum et al 2006b;Helfferich 1962;Harland 1994). However, column tests require significant effort; they require about 1 gallon of filtered tank waste supernate diluted to process specification, work in a shielded hot cell facility, and about 2 weeks of actual process time and sample collection, followed by sample analysis.…”

“…Resorcinol-formaldehyde resins are characterized with greater chemical stability to alkaline solutions and can selectively remove Rb and Cs at high background concentrations of Na + [14]. RF-resins are used mainly under dynamic conditions, when ion-exchanger is put into the sorption column with consequent feeding of LRW [15]. RF-resins were also used in the form of spheres to treat highly mineralized LRW followed by radionuclide desorption using HNO 3 solution [2,[16][17][18].…”

Porous ion-exchanging resorcinol-formaldehyde resins were prepared by removing an inorganic template (CaCO3) and by polymerization of a highly concentrated emulsion with toluene as a dispersing phase. As compared to original resorcinol-formaldehyde resins, the porous one is characterized with higher values of internal diffusion, providing exceptional purification coefficients. However, the amounts of the introduced CaCO3 and toluene have to be below 10 wt.% and 25 wt.%, respectively, to avoid fast degradation of the ion-exchanger. Under dynamic conditions, average purification coefficients in the model solution of Cs-137 are twice higher than those of the non-porous sample. The prepared porous ion-exchange resin can be used in cases when high Cs-137 uptake from liquid media should be realized at increased rates of solution percolation.

“…The purpose of this document is to provide the function and requirements for the Radioactive Waste Test Platform (hereafter called "test platform"). Historically, testing has been performed at the bench scale with actual waste samples (Fiskum et al 2006a(Fiskum et al , b, 2008(Fiskum et al , 2009Lumetta et al 2009;Edwards et al 2009;Smith et al 2000Smith et al , 2001. These tests form the basis for waste treatment operations at the Hanford Site.…”
