Take steps on SNF and HLW disposal
Matt Bowen
With a new administration and Congress, it is time once again to ponder what will happen—if anything—on U.S. spent nuclear fuel and high-level waste management policy over the next few years. One element of the forthcoming discussion seems clear: The executive and legislative branches are eager to talk about recycling commercial SNF. Whatever the merits of doing so, it does not obviate the need for one or more facilities for disposal of remaining long-lived radionuclides. For that reason, making progress on U.S. disposal capabilities remains urgent, lest the associated radionuclide inventories simply be left for future generations to deal with.
In March, Rick Perry, who was secretary of energy during President Trump’s first administration, observed that during his tenure at the Department of Energy it became clear to him that any plan to move SNF “required some practical consent of the receiving state and local community.”1

Controlled reflux was studied as a method for improving the efficiency of removing strontium from solution by foam separation. Tests were performed with solutions containing 85S, 10−6 M Sr2+ carrier, and 90 to 100 ppm of the surfactant sodium dodecyl benzene sulfonate (NaDBS) in either distilled water or 0.005 M NaOH to 0.005 M Na2CO3 solution. Nearly constant feed rates were maintained at about 40 gal/ft2 of column cross section per hour. With these conditions, the volume reduction factor was increased to 3700 (from a value of ≈ 30 for nonrefluxing systems) and the strontium decontamination factor was in excess of 103. In general, the volume reduction was inversely proportional to the gas/liquid volume ratio but directly proportional to the percent of foam reflux; the strontium decontamination factor, however, did not change very much within the throughput range studied.
