ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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 experimental assembly to study irradiation effects on the compatibility of BeO with graphite at 1500°C held one-inch-diameter rings of BeO and graphite in close contact for nine-months exposure at 1200 to 1500°C for a neutron dose of 1 × 1021 n/cm2 (E > 0.18 MeV). Postirradiation evaluations indicated that no chemical reaction had occurred. The components of the irradiated assembly were sampled and analyzed for 6Li. It was found that a massive BeO component (1-in. diam by 4.5-in. long) retained a major portion of the 6Li which was generated within it during the irradiation. No gross radiation-induced physical damage was observed in either the BeO or the graphite components. The physical changes observed were in general agreement with previously reported results.
