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.

Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

During yield operations, the materials within the National Ignition Facility (NIF) cryogenic target positioner will be exposed to high fluences of high-energy neutrons. If left unchecked, these neutrons could deposit unacceptably high amounts of energy within the cryogenic fluids. In addition, these neutrons will induce residual radioactivity within the target positioner and may lead to intolerable dose rates for maintenance personnel. Through careful design and selection of materials, however, these effects may be mitigated. The present work uses nominal design characteristics for the cryogenic target positioner to show that traditional cryogenic and structural materials will not produce an acceptable design. Further, we develop an alternate design that addresses the issues of neutron shielding and activation.
