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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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?

For the destruction of nitric acid in radioactive waste solutions from the reprocessing of nuclear fuel, a batch process has been developed using formic acid as a reducing agent. The main reaction products are N2O and CO2, which can be discharged into the environment. The process has been tested on a lab scale with simulated and real waste solutions as well as on a pilot scale with simulated solutions. Nitric acid turnovers between 80 and 90% are obtained. The final nitrate concentrations in high- and medium-level waste solutions are below 0.5 and 0.2 mol.ℓ−1, respectively. The induction period that occurs when starting the reaction can be described by a reaction rate equation. For our special conditions it lies within the range of a few seconds. The loss of solid particles and formic acid into the off-gas during the whole process amounts to a few parts per million. Corrosion tests under realistic conditions have shown that Incoloy 825 is an appropriate material for the denitration vessel.
