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?

A small-scale semicontinuous pilot plant for studying chemical reactions carried out in remote environments is described. The all-stainless system features modular construction enabling rapid exchange of various elements. The equipment design permits purification, sampling, and other manipulative tasks to be performed in a “safe” operating area. Dissolved gases and moisture are removed from the reactant mass prior to circulation in the primary reaction loop. In this particular application, moisture is removed by low-temperature adsorption on molecular sieves. Progress of the drying is monitored continuously by a commercially available instrument in which moisture passes through a semi-permeable foil to a capacitance element. The rate of reaction in the remote reaction zone is reflected continuously in the time rate of change of conversion as measured by in situ differential refractometry. Utilization of this system has permitted accurate measurement of the rate of 60Co radiation-induced polymerization under super-dry conditions.
