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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Measurements have been made of the decay constant of thermal neutrons in water poisoned with boron and with the non-1/v absorber cadmium. An experimental method has been used in which proper spatial integration of the neutron flux enables data that are representative of the infinite medium to be accumulated without waiting for the establishment of a fundamental mode distribution. The measurements yield effective absorption cross sections in good agreement with presently adopted values. The change in effective absorption cross section with concentration of the dissolved cadmium (dσeff)/ (dN) has been determined for an infinite medium at 20°C. Two- and three-parameter fits of the decay constant yield −(0.32 ± 0.09) · 10−17 b cm3 and −(0.47 ± 0.10) · 10−17 b cm3, respectively, for the coefficient (dσeff)/ (dN). Earlier published measurements have resulted in two to five times larger values, whereas a published calculated value for Nelkin's model is −0.33 · 10−17 b cm3.
