Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

We have hydrided thin (500 nm) films of Er with tritium to a stoichiometry of ErT2, and have been observing their 3He release characteristics at very low 3He/Er ratios. The films are stored in vacuum-tight metal containers and sampled on a timescale ranging from a day to several months. Analysis is performed with very high sensitivity using static noble gas mass spectrometry. For the first several years, 3He release is a fairly constant function of helium generation, and does not depend on the amount of helium accumulated in the film. There appears to be somewhat higher helium release at very early times (up to 2%), decreasing over 6 months to a fairly flat value (0.7%). This observation is consistent with a bubble nucleation and growth mechanism. The very early release behavior does not appear to be dependent upon the presence or growth of surface oxide layers.
