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.

Off-axis neutral beam (NB) current drive (CD) (NBCD) has the potential to supply substantial off-axis CD for the demonstration steady-state, Advanced Tokamak scenarios. A modification of the two existing DIII-D NB beamlines is proposed to allow off-axis CD with NB injection (NBI) vertically steered to drive current as far off axis as half the plasma radius. The profile and magnitude of the driven current is calculated using the NUBEAM Monte Carlo module in the TRANSP and ONETWO transport codes. When the beam is injected in the same direction as the toroidal field, off-axis CD of [approximately equal to]45 kA/MW is calculated at normalized radius (square root of the toroidal flux), = 0.5 with full-width at half-maximum of 0.45 in . The dimensionless CD efficiency is comparable or somewhat better than that for electron cyclotron CD (ECCD) at the same location and plasma parameters. The efficiency stays nearly constant in going from on-axis to off-axis CD. The localization and magnitude of the off-axis NBCD are sensitive to the alignment of the NBI relative to the helical pitch of the magnetic field lines and thus to the direction of the toroidal field and plasma current. The driven current is still localized off axis for fast ion diffusivities up to 1 m2/s. The calculations show that the off-axis NBCD can supply much of the off-axis CD for the steady-state scenarios under consideration, leaving ECCD for fine-tuning of the current profile and real-time control.
