Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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?

A station has been installed at the Rocky Flats Nuclear Safety Laboratory to volume-calibrate their storage tank farm housing 560 kg of enriched (93.2% 235U) uranium solution. The calibration (relating contained solution volume to height) of tanks used to store or process fissile materials is often complicated by the large surface area presented by thousands of borosilicate glass rings used for criticality prevention. Yet, an accurate and reliable measurement of this relation is important to good material accountability and possibly to nuclear safety. The latter purpose can be served by detecting accumulations of insoluable precipitates or the formation of critically unsafe voids in the bed of rings. With this station, calibrations are easily accomplished with an accuracy better than 1 liter at any point within a 500-liter tank. Additional benefits include increased safety through reduced potential for contamination release, improved efficiency since one operator replaces the previously required two, and the complete elimination of both solid and liquid contaminated waste generation.
