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.
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.

NC State celebrates 70 years of nuclear engineering education

The Department of Nuclear Engineering at North Carolina State University has spent the 2020–2021 academic year celebrating the 70th anniversary of its becoming the first U.S. university to establish a nuclear engineering curriculum. It started in 1950, when Clifford Beck, then of Oak Ridge, Tenn., obtained support from NC State’s dean of engineering, Harold Lampe, to build the nation’s first university nuclear reactor and, in conjunction, establish an educational curriculum dedicated to nuclear engineering.
The department, host to the 2021 ANS Virtual Student Conference, scheduled for April 8–10, now features 23 tenure/tenure-track faculty and three research faculty members. “What a journey for the first nuclear engineering curriculum in the nation,” said Kostadin Ivanov, professor and department head.

Burning plasma spherical tokamaks (STs) rely on off-axis current drive (CD) and nonsolenoid start-up techniques. Electron Bernstein waves (EBWs) may provide efficient off-axis heating and CD in high-density ST plasmas. EBWs may also be used in the plasma start-up phase because EBW absorption and CD efficiency remain high even in relatively cold plasmas. EBW studies on the Mega Ampere Spherical Tokamak (MAST) can be subdivided into four separate subjects: thermal electron cyclotron emission observations from overdense plasmas, EBW modeling, proof-of-principle EBW heating experiments with the existing 60-GHz gyrotrons, and EBW assisted plasma start-up at 28 GHz. These studies are also aimed at determining the potential for a high-power EBW system for heating and CD in MAST. The optimum choice of frequency and launch configuration is a key issue for future applications in MAST. This paper describes diagnostics, modeling tools, and high-power radio frequency systems developed specifically for EBW research in MAST. The experimental methodology employed in proof-of-principle EBW heating experiments along with experimental results is discussed in detail. EBW heating via the ordinary-extraordinary-Bernstein (O-X-B) mode conversion has clearly been observed for the first time in an ST.
