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.

One of the peculiar characteristics of the HANBIT discharge is that plasma density varies as stepwise manner on applied RF power and there does not exist stable discharge between the each of steps.We believe that the plasma density is determined as the balance of loss power caused by transport and absorbed power coupled with radio frequency antenna. According to previous simulation concerning RF wave coupling with the plasma, the antenna loading impedance or the plasma resistance is very peaky on the plasma density variation. It implies that the plasma impedance at the density at which the power is balanced is not continuous on applied RF power. Even though the plasma resistance is very sensitive to the plasma conditions of density and external magnetic field and have peaky dependence on plasma conditions, up to now we have used fixed RF matching condition and successfully implemented discharge experiments. To investigate the characteristics of density variation on applied RF power and reason how does the impedance well adjust to separated discharge conditions, we performed self-consistent discharge simulation. The results well explain the behavior of the plasma density on applied RF power and the reason why we can use fixed matching condition for various plasma conditions.
