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.

Atomic Museum marks 20 years of education
The National Atomic Testing Museum, better known as the Atomic Museum, is celebrating its 20th anniversary this year. Located in Las Vegas, Nev., the museum was established in 2005 to preserve the legacy of the Nevada Test Site, now called the Nevada National Security Sites.

In 1971 the French Atomic Energy Commission (CEA) established itself as a candidate for 252Cf commercial encapsulation services. A production facility, designed and built at the Fontenay-aux-Roses Centre for Nuclear Studies, allows handling of up to 10 mg of 252Cf. This unit started operation in Sep. 1973. The main features of the californium facility are: (a) remote manipulation by means of two electrical robots, (b) TIG welding of capsules and assemblies using two machines, with variable positioning of the electrode along the three axis that allows the soldering of pieces as large as 50 mm in diameter and 2 m in length, (c) capsule decontamination by an electrolytic pickling technique, and (d) neutron source emission counting by means of a uranium fission chamber giving relative measurements versus a 252Cf standard with an accuracy of 3%. All sealed sources developed at the CEA are made of 252Cf2O3-Pd cermets encapsulated in stainless steel, Zircaloy, or nickel and are qualified as special form nuclear material. Present applications of 252Cf sealed sources in France are directed toward physical research and nuclear reactor design, nuclear reactor startup and nuclear materials assay, neutron activation analysis development for in situ determinations in the earth science and mineral exploration, and for process control in metallurgy. Furthermore, the CEA is involved in a government-sponsored program on a 252Cf source projector for neutron therapy. For the afterloading interstitial technique, the CEA has designed miniaturized sources made of a 252Cf2O3-Pd cermet containing 0.32 μg of 252Cf sealed in a platinum capsule 0.70 mm in diameter and 4 mm long.
