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?

Received August 4, 1981 Accepted for Publication March 18, 1982 The uranium ore requirement under a given world energy demand scenario is studied for the light water reactor, high temperature reactor (HTR), and fast breeder reactor (FBR), respectively. Both HTRs, when operated in the thorium fuel cycle, and FBRs achieve favorable conservation of uranium, but in different chronological periods: the HTR during the introductory phase of the nuclear power for ∼100 yr; the FBR during the later phase of saturation for many centuries. The advantages can be combined by introducing both systems in parallel, which brings a definite further improvement. Beyond that, the world uranium requirement can be limited to a total of 5 million Mg if accelerator breeders or fusion-fission hybrids are introduced for breeding 233U out of thorium starting 40 yr from now.
