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.

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.

Cryogenic pumps are convenient machinery for handling hydrogen isotopes in fusion fuel processing systems. Not only ultra-vacuum pumps working at such as liquid helium or hydrogen temperature but also sorption pumps using liquid nitrogen are applicable. The latter type is suitable to a means of temporary storage and/or transportation between process units. In the cryogenic pumping, there is an issue that the pressure in a pump is not necessarily identical with the pressure measured in its evacuating vessel in equilibrium, because of an effect of thermal transpiration. Thermal transpiration is important in adsorption isotherms which characterize cryo-sorption pumping. In this study, the effect of thermal transpiration was investigated for He, H2 and D2 in a closed system consisting of a volume at room temperature and a volume at cryogenic temperature, connected together by a simple narrow pipe or a pipe containing baffle plates as thermal shield. The effect is here described by an equation of nominal-distribution function with respect to the pressure measured in the hot end volume. Defining an effective inner diameter for the latter pipe, agreement is shown of characteristic curves for geometrically different pipes. The error-functional curves for H2 and D2 are agreed together. The curve for He is also perfectly approximated but with a constant shift. This shift results in the difference of a molecular property among He, H2 and D2.
