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?

Specimens of SYNROC B were fabricated under a variety of conditions and doped with simulated radwaste species. Two of the component phases of SYNROC B, perovskite and zirconolite, doped with strontium and uranium, respectively, were also fabricated. All specimens were carefully characterized for both phase content and dopant partitioning via x-ray diffraction and electron beam microanalysis techniques. These specimens were then subjected to neutron activation and leached, and the leachant was analyzed by gamma spectrum analysis. All data were compared with similar analyses of Pacific Northwest Laboratory glass 76-68, a borosilicate glass. It was found that both perovskite and properly prepared SYNROC B leach at about the same rate as the borosilicate glass, while zirconolite appears to be at least an order of magnitude more resistant to leaching. When SYNROC is prepared under undesirable conditions and contains Ba2Ti9O20, cesium leach rates are one to three orders of magnitude higher than in the correctly composed SYNROC B.
