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.

Nuclear waste contains a significant amount of long-lived non-gamma-emitting nuclei such as 129I and 14C. A method of nondestructive detection for monitoring long-lived waste products is proposed as an application of the (,n) reaction. This method is useful for surveying long-lived "difficult-to-measure" nuclides, e.g., 129I. Iodine-128 produced from the reaction of 129I(,n)128I emits gamma rays that can easily be measured by a gamma-ray counter. We measured the inclusive photonuclear 129I(,n)128I reaction cross section induced by bremsstrahlung photons. The photons were produced at a Ta target bombarded by 30-MeV electrons from a linear accelerator. The intensity of the slow neutrons was considered in the reactions of 127I(n, )128I and 129I(n, )130I. The activity of 128I was measured by a high-purity germanium spectrometer. The gamma-ray flux and the neutron flux were calculated using the EGS and MCNP codes, respectively. The average activation cross section of the 129I(,n)128I reaction had a 12% deviation from the evaluated International Atomic Energy Agency photonuclear data.
