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 buildup of radioactivity was measured on Type 304 stainless steel and carbon steel coupons exposed to reactor water in a test loop, which operated for ∼3 yr in a commercial boiling water reactor. Most of the activity buildup could be ascribed to 60Co. After an initial rapid increase, the activity buildup slowed down and kept increasing linearly up to 10 000 h of effective exposure to reactor water. No correlation was found between the 60Co activity in reactor water and the 60Co activity on the coupons. Preoxidation of Type 304 stainless steel coupons reduced the initial activity buildup. Carbon steel picked up much less activity than stainless steel during the tests. Measurements of the activity buildup after filtration of the primary coolant indicated that soluble impurities rather than particulates are primarily responsible for the radiation buildup phenomena. Increasing the coolant velocity also resulted in a reduction of the initial activity buildup on the coupons.
