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?

Solubility effects were measured on ceramic and single crystal alumina, titania, SrTiO3 (perovskite structure), and ceramic zirconia at 300 and 400°C for times of 7 and 18 days. Selected fluids were deionized water, a high-bicarbonate, high-sulfate simulated connate water (∼1% total dissolved solids), saturated NaCl brine, and a high-magnesium, high-calcium bittern brine. There is measurable dissolution of Al3+ in the connate water and in the bittern brine only. In both cases this can be related to the low pH conditions expected in these fluids at high temperature and to the increase in aluminum solubility with decreasing pH. The SrTiO3 breaks down to some extent in all fluids in the order bittern brine >NaCl >bicarbonate water >deionized water. Dissolution attack on both titanium and zirconium oxides is very small, indicating that the oxides are stable in the pressure-tempera-ture-fluid composition regime. Breakdown of the perovskite phase appears to be by incongruent dissolution with concurrent precipitation of the titanium oxide.
