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?

Chemical analysis techniques were demonstrated for three uranium nitride specimens. Sintered uranium mononitride (UN), unsintered UN powder, and UN1.572 powder were analyzed for the major constituents, and a mass balance of 100.00 ± 0.03% was realized in every case. The gravimetric determination of uranium in these materials by an oxidation-reduction-oxidation method gave good precision and accuracy. Results from the direct oxidation method were strongly dependent on the oxygen content of the gas used to oxidize the sample. The controlled-potential cou-lometric method was used to confirm the gravimetric uranium results. The Dumas method for nitrogen determinations was shown to be superior to the Kjeldahl for both UN and UN1.572. Inert gas fusion is suitable for the determination of oxygen and a conventional combustion method is suitable for carbon determinations. Sintered UN provided a mass balance of 99.989% with a mole ratio N+O + C/U = 0.997 and a crystal lattice parameter a = 4.8896 ± 0.0001 Å. The micro structure of this sample consisted of single phase mononitride.
