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.

Analyses of property changes during reirradiations and anneals show that the technique of alternate reirradiations and anneals can be used consistently to remove radiation damage from graphite. Laboratory experiments, monitoring studies and reactor-height measurements all correlate favorably. It is shown that the recovery for a reirradiation and annealing cycle is independent of irradiation temperature between 30 C and 200 C and total damage over wide ranges. The reciprocal of the recovery per cycle is a linear function of the exposure between anneals with a slope that is determined by the anneal temperature.
