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?

The Isotopes Division of Oak Ridge National Laboratory has developed procedures for providing accurately defined deposits of 239 PuO2 and 235 UO2 for use in precision neutron cross-section measurements. Encapsulated samples of 6Li, 10B, 45Sc, 232Th, 235U, 238 U, 237Np, 238Pu, 239Pu, and 241 Pu for use as neutron monitors in reactors can also be provided. These dosimeters are used to determine integral reaction rates from which the neutron energy spectrum, flux, and fluence at particular locations within a reactor can be computed. Methods for the preparation and characterization of reactor dosimeters and other reaction rate samples provide an accuracy of ≤±1% at the 95% confidence level (CL).
