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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

This panel will discuss how the emerging compounds called PFAS/PFOS or "forever chemicals" have impacted the decommissioning of both nuclear plants as well as DOE facilities with respect to license termination. This panel will host Industry Subject Matter Experts (SMEs) to provide an overview of the chemical properties that lead to their wide used across industries and why they are in the focus of many community oversight committees and state/federal agencies. This panel will also host representatives from Nuclear Plants and DOE facilities to share their lessons learned with respect to the characterization and remediation of impacted media, and the challenges faced as state cleanup levels are being approved at values often far lower than EPA's Maximum Contaminant Limit (MCLS).
