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 new method for management of waste Zircaloy fuel hulls is proposed as an alternative to compaction and burial. It involves using the waste as a feedstock in a chemical process for preparing inorganic zirconate ion exchange material. Enough zirconate could be prepared from the waste hulls to stabilize all the high-level liquid waste generated in light water reactor fuel reprocessing, and in this way the two waste streams would be combined. The proposed conversion operation would involve chlorination of the Zircaloy waste with NH4Cl and distillation of volatile chlorides, reaction of the distillate with isopropyl alcohol to form intermediate alkoxides, and hydrolysis of the intermediate to form the zirconate. The conversion would be accomplished with recycle of all reagents so that no new major waste stream would be created. The chemical basis for the conversion process, simplified process flowsheets, and an analysis of the various options illustrate the feasibility of the full-scale process. A preliminary economic study was made that indicated that the full-scale operation should be technically and economically feasible.
