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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

Nuclear new build procurement considerations
It may seem counterintuitive, but the best time to enhance the ability to support operations and maintenance for a new plant is before construction starts. This is one of many lessons learned by the currently operating nuclear fleet. As construction and startup of many nuclear facilities was completed, it quickly became evident that the ability to efficiently support operations and maintenance was limited. Most of the information necessary to establish and manage procurement of spare and replacement items, maintenance, and configuration of the facilities was unavailable and had to be gathered on a case-by-case, “on-demand” basis. Absence of necessary information and the associated challenges resulted in the need for staff augmentation and multiyear-long projects to develop equipment bills of material and maintenance programs and to perform technical evaluations for the huge quantities of spare and replacement items being requested.

An outline of Next European Torus safety and its impact on the environment is presented. Included are a short characterization of the basic safety approach, current radiological recommendations, and the potential hazards due to tritium, neutron-induced radioactivity, and energy inventories. Significant accidents that could be initiated and propagated by these energies and finally lead to releases of radioactivity are characterized by typical initiating events such as after-heat under loss-of-cooling conditions and ruptures of blanket components. The environmental impact of releases is dealt with by reporting experimental results on tritium behavior in the environment as well as by broadly quantifying tritium dispersion and activation product releases under both routine and accidental conditions. Finally, the categories of wastes produced, their approximate amounts, and a strategy for their final disposal are presented.
