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.
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.

Destruction of Ukrainian dam threatens Zaporizhzhia
A Soviet-era dam downstream from the Zaporizhzhia nuclear power plant in southeastern Ukraine collapsed last evening, causing the water level of the Kakhovka Reservoir north of the dam to drop and raising new concerns over the already jeopardized safety of the Russian-occupied nuclear facility, Europe’s largest. The reservoir supplies water for, among other things, Zaporizhzhia’s cooling systems.

Simulation of reactor antineutrino signatures is vital to verify the experimental measurements of antineutrinos emitted from a reactor. It also provides an insight into detector configurations required to monitor different reactor types and potential fuel diversion scenarios. In this study, we perform simulations of antineutrino signatures for light water reactors (LWRs) using the industry standard reactor simulation tools, CASMO-4 and SIMULATE-3. Three different LWR reactors have been modeled, and several diversion scenarios involving uranium dioxide and mixed-oxide fuel have been simulated. The simulation results are also benchmarked with the antineutrino counts measured by the SONGS1 antineutrino detector that was used to monitor the operation of San Onofre Nuclear Generating Station (SONGS), unit 2, cycle 13, during the period 2004-2005. Three-dimensional simulations of the reactor cores have been performed for improved accuracy of the detector response. The dependence of the antineutrino rate on the reactor type, fuel loading pattern, and amount of fresh fuel have also been analyzed.
