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.

The discrete gamma radiation in the interaction of 14.9-MeV neutrons and a natural copper sample is investigated with the total gamma radiation measurement technique. One hundred seven prompt gamma rays, which come mainly from the reactions (n,n'), (n,2n), (n,np), (n,d), (n,p) and (n,) of 63Cu and 65Cu, are identified by a high-resolution gamma-ray analysis code. According to the systematic knowledge of 14.9-MeV neutron-induced 63,65Cu(n,x) reactions, nine final nuclei are identified, and 139 possible transitions are designated. The differential elemental production cross sections of 107 gamma lines at 90 deg and 79 gamma lines at 55 deg are determined. The nine integral isotopic cross sections of 11 reaction channels including 63Cu(n,n')63Cu, 63Cu(n,2n)62Cu, 63Cu[(n,np) + (n,d)]62Ni, 63Cu(n,p)63Ni, 63Cu(n,)60Co, 65Cu(n,n')65Cu, 65Cu(n,2n)64Cu, 65Cu[(n,np) + (n,d)]64Ni, and 65Cu(n,p)65Ni are also obtained. The present results are in good agreement with some recent experimental and evaluated results.
