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.

A neutron production rate (NPR) of 2.3 × 106 1/sec has been achieved in a spherically convergent D-D fusion neutron generator with the applied voltage 60 kV and the steady-state discharge current 40 mA. The scaling of NPR with respect to the current, however, is linear. The results revealed the fact that the fusion reaction occurs mainly between the accelerated molecular ion D2+ and neutral gas D20. In considering a future application of the neutron source, the dependence on a square current, i.e., the fact that the main reactions are caused by accelerated ion beam-beam colliding fusions is most desirable. A new IEC device has been constructed in order to obtain evidence of beam-beam colliding fusions. The device is designed to operate in a short pulse of the voltage -70 kV and the large current 100 A. This is the first experiment to draw a current of several tens of amperes in IEC devices. The discharge characteristics were studied with regard to the relations of the current, applied voltage and gas pressure. The neutron production rate was also measured, and the conditions to realize accelerated ion beam-beam fusion are discussed.
