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.

In the case of a fire accident in a fusion plant, tritiated organic substances will be produced. We have developed a Pd/ZrO2 catalyst applicable for the oxidation of tritiated organic substances. In this study, two different weight ratios of palladium, 5 and 10 g/l, were selected. The overall reaction rate constant of tritiated methane oxidation with the palladium catalysts in a flow-through system were determined as a function of space velocity from 1200 to 7000 h-1 , methane concentration in carrier from 0.004 to 100 ppm, and temperature of catalyst from 323 to 673 K. As-received catalysts showed a large overall reaction rate constant over the whole tested temperature range. However, the constants gradually decreased after a while. The considerable decrease was evaluated especially over the lower temperature range. The decrease has been explained as caused by the layers of produced water that formed on the surface of the catalyst playing the role of obstacle to reactant transport onto the noble metal deposited on the catalyst. The performance of 10 g/l catalyst was superior to that of 5 g/l over the whole tested temperature range. The overall reaction rate constant was dependent on the space velocity and independent of methane concentration in the carrier.
