Reboot: Nuclear needs a success . . . anywhere
The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.
Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?
As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?

Field-flow fractionation (FFF) is a versatile analytical separation technique that has proven to be applicable to a wide range of polymers, colloids,and fine oarticles over the effective molecular weight range 103 to 1016, corresponding to diameters of 0.001 to 30 µm. Several subtechniques of FFF have been developed for which there are precise theoretical relationships of retention to particle parameters. Fractionation takes place in a thin flow channel by the interaction of a lateral field (gravitational or centrifugal in the case of sedimentation FFF, cross flow in flow FFF, electrical in electrical FFF, and temperature differential in thermal FFF) with the flow profile. Steric FFF, a limiting form of FFF, is applicable to the largest particles, from 1 up to 30 μm or more in diameter, and can also be used in a preparative mode. Altogether FFF has the potential of separating and characterizing radioactive species and the diverse materials with which they are associated in the environment over a size range where analysis by conventional techniques is difficult or impossible.
