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.

ARG-US Remote Monitoring Systems: Use Cases and Applications in Nuclear Facilities and During Transportation
As highlighted in the Spring 2024 issue of Radwaste Solutions, researchers at the Department of Energy’s Argonne National Laboratory are developing and deploying ARG-US—meaning “Watchful Guardian”—remote monitoring systems technologies to enhance the safety, security, and safeguards (3S) of packages of nuclear and other radioactive material during storage, transportation, and disposal.

Photon buildup factors provide a convenient method for radiation protection professionals to calculate dose and exposure behind various shielding configurations. Examination of buildup factors can also provide insight into the behavior of photons in these shields. Recent work has developed dual-layer buildup factors for several shielding configurations and a limited number of energies while slant-path buildup factors have been developed for single-layer shields. This work develops slant-path buildup factors for slab-geometric, dual-layer shields comprising polyethylene and lead at 25 energies conforming to the energies used in the buildup factor standard ANSI/ANS-6.4.3-1991 (W2001), “Gamma-Ray Attenuation Coefficients and Buildup Factors for Engineering Materials,” between 10 keV and 10 MeV. Further, the increased energy resolution of the calculations performed in this work allows the energy at which the previously identified “buildup reversal” phenomenon occurs to be more precisely identified. The effect of mesh spacing and quadrature resolution on fluence through the shields is also considered.
