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.

Since the introduction of the angular segmentation or Sn method some 60 years ago, there have been many advances in the understanding of the method and many improvements to it. Indeed, the Sn method is now a widely used technique for deterministic solution of the transport equation. For three-dimensional (3-D) calculations, the method relies on numerical quadratures for the sphere, which integrate certain subspaces of spherical harmonics. The construction of such quadratures can be difficult. Here we report the development of new, highly efficient quadratures for the sphere that are invariant under the icosahedral rotation group. We compare the efficiency of the standard level-symmetric quadratures commonly used for 3-D Sn calculations and see that the new quadratures can be as much as 70% more efficient than the standard quadratures.
