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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Miniaturized specimen technology enables mechanical behavior determination using a minimum volume of material. A method for obtaining the ductile-brittle transition temperature (DBTT) of ferritic steels was developed using a miniaturized notch test (MNT Comparisons between conventional and miniaturized specimen DBTTs show that the MNT specimens are capable of delivering a 41-J transition temperature shift with the same accuracy as that obtained using conventional specimens. The work reported here was performed on an American Society for Testing Materials A508 steel. Based on the promising results obtained, future work should be directed toward benchmarking and assessing the uncertainty of the method for other pressure vessel steels.
