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.

The 10B(n,0)7Li and 10B(n,1)7Li angular distributions have been measured at the Geel Electron Linear Accelerator time-of-flight spectrometer in the incident neutron energy range from 0.1 keV to 1 MeV. A twin Frisch-grid ionization chamber has been used with two very thin 94% 10B-enriched samples mounted back-to-back on the common cathode. With this type of charged-particle detector, it is possible to measure the angular distribution of the alpha particles in a nearly 2x2 solid angle, with a clear separation of the alpha-particle yields from both reaction channels: -emission to the 7Li ground state {0} and to its first excited state {1}. Hence, for the first time nearly the full solid angle at all incident neutron energies investigated has been covered. A strong angular anisotropy was observed and is discussed in the frame of the compound nucleus reaction mechanism. The alpha-particle center-of-mass angular distributions have been used to calculate the branching ratio 10B(n,0)/10B(n,1). Both data sets had a strong impact at the International Atomic Energy Agency Coordinated Research Project “Improvement of the Standard Cross Sections for Light Elements” and the corresponding evaluation of the standards data file for this reaction.
