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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Correlations of data characterizing arrays of subcritical units that interact to render whole arrays critical show that the resulting thickness of fissile material solution contained in an array, when “smeared” over the base area of that array, can be compared to the thickness of a single homogeneous unit having a composition and shape similar to that of the array. The correlations resulted in curves that can be used to predict critical arrays of solutions or to determine safe spacing using appropriate safety factors. Although the same relationship between array-smeared thickness and single-unit thickness does not appear to apply to metal systems, a useful curve that guides the determination of criteria for adequate spacing is developed.
