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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.

Neutron energy spectra at 90 deg produced from stopping-length graphite, aluminum, iron, and lead targets and at 180 deg produced from a thin lithium target bombarded with 140-MeV protons were measured in the irradiation room of the neutron time-of-flight (TOF) course at the Research Center of Nuclear Physics of Osaka University. The neutron energy spectra were obtained by using the TOF technique in the energy range from 10 MeV to the incident proton energy of 140 MeV. The experimental data for a thick target at 90 deg were compared with calculations performed with the Particle and Heavy Ion Transport code System (PHITS) using the evaluated nuclear data. It was shown that PHITS using the evaluated nuclear data is able to reproduce the secondary neutron spectra at 90 deg. The experimental data for a thin target at 180 deg were compared with calculations using the nuclear physics models in PHITS and the Monte Carlo N-Particle eXtended code (MCNPX). We found that the two codes work well at 180 deg in the neutron energy region above 10 MeV.
