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?

Satisfactory performance of superalloy capsules at conditions typical of those expected in radioisotopic heat sources was demonstrated. Capsules of Hastelloy X, Hastelloy C, InconeI 600, and Haynes 25 were heated in air at 850 to 1000°C; those containing unirradiated cobalt metal were tested for up to 39 400 h (4.5 yr), and those containing irradiated cobalt metal for up to 19 500 h (2.2 yr). These tests indicated that Hastelloy X is the best encapsulating material for these applications , and Hastelloy C is a good alternative. General agreement of the data on inactive and active capsules indicates that the performance of active capsules is not significantly affected by the radiation field or the buildup of nickel from radioactive decay of the cobalt.
