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?

An evaluation of the radiation from higher exposure light water reactor fuel that is of significance in shipping container design has been made. Because these fuels contain significant quantities of transplutonium nuclides, it has been established that the neutron emission rate and the associated biological dose rate are of large enough magnitude to require special consideration in the shielding design. This analysis is based on experimental determination of heavy element nuclide concentrations in both PWR and BWR fuels and the use of ANISN-type shielding calculations. The results indicate that a conventional cask would not have sufficient neutron shielding capability to permit shipment of spent fuel with exposures in excess of ∼22 000 MWd/MT. Hence, a new generation of shipping casks with specific provisions for neutron shielding is required.
