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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Laser powder bed fusion (LPBF), also known as selective laser melting, of Glenn Research Copper 84 (GRCop-84), a Cr2Nb (8 at. % Cr, 4 at. % Nb) precipitation-hardened alloy, produces a fully dense, high-conductivity alloy with tensile strength (470-MPa yield and 710-MPa ultimate tensile strength) superior to other competing copper alloys. Agglomeration and coarsening of precipitates in gas atomized GRCop-84 powder occurred above a threshold of 17 μm in diameter. Area of precipitates within cross sections is consistent among powder particles of different diameters indicating a consistent atomization process. Precipitates within gas atomized powder were shown to either melt and subsequently re-precipitate as the melt pool rapidly cools or break apart during LPBF resulting in precipitates smaller than in the initial powder. Precipitate size in powder therefore does not affect precipitate size, and thus tensile strength, in LPBF GRCop-84.
