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.

The fire that powers the universe: Harnessing inertial fusion energy
It was a laser shot for the ages. By achieving fusion ignition on December 5, 2022, Lawrence Livermore National Laboratory proved that recreating the “fire” that fuels the sun and the stars inside a laboratory on Earth was indeed scientifically possible.

The present shortage of fast reactor test space, particularly for test regions > 2cm in diameter, led to a series of tests to develop an adequate spectrum-hardening filter so that a suitable fast-neutron flux environment could he obtained in a large thermal test reactor. A boron filter was the best of a number of filter materials tested, and verification measurements were made in the Engineering Test Reactor II (ETR) Critical Experiment. After several design modifications, fast-neutron flux spectra typical of the Experimental Breeder Reactor II (EBR-II) were obtained at levels ∼½ of those obtainable in the peak region of the EBR-II but with a test hole diameter of 3.5 cm. Softer neutron spectra, typical of some of the proposed fast breeder designs, can be obtained in a filtered ETR experiment with fissile fission rates greater than those in the EBR-II.
