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.

Neutron kinetics investigations at the zero-power LR-0 reactor in Czechoslovakia are described. The reactor is fueled with WWER-1000 assemblies. Reactivity perturbations generated by absorber cluster movements are investigated. It can be shown that, under certain conditions, space-dependent effects can be corrected by a simple model. The experimental results are used to verify a nodal three-dimensional, two-group neutron kinetics code.
