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?

This report presents the results of a study of the design and use of pinhole gamma-ray cameras in examining irradiated fuel rods nondestructively. A theory is presented for the performance in terms of sensitivity, resolution, field of view, contrast, and magnification. The performance is described in terms of parameters that are analogous to those used in describing ordinary visible-light cameras. Several cameras were built of depleted uranium to achieve a desired level of resolution and sensitivity. All the cameras have been used successfully to examine irradiated fuel pins nondestructively, and are capable of demonstrating damage, swelling, and cracking in fuel rods. Resolution is of the order of 10 to 20 mils depending on the average photon energy of the source being viewed; they have a 3½-in.-diam field of view at a distance of 2 ft from the camera's center.
