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.

In conventional electron cyclotron resonance heating systems, beam steering for current drive is achieved by rotating the mirrors of the launcher. Alternatively, it could be achieved remotely using a rectangular/square-corrugated waveguide (SCW). Symmetric beam steering is achieved at a length L (8a2/), where "a" is the width of the waveguide and "" is the wavelength of the microwave while at L/2 (4a2/) antisymmetric steering is seen. At a length of 2a2/, beam splitting into two equal lobes is observed.A low-power experiment on a remote steering antenna is carried out with an SCW at 2a2/ and a plane fixed mirror at the exit of the SCW, which diverts the microwave beam in one direction. The microwave instrumentation consists of a Gunn oscillator (82.6 GHz/~40 mW/TE10), an isolator, an attenuator, waveguides, and a mode converter (TE10 to HE11). The output of the mode converter is a 63.5-mm-diam corrugated waveguide, which couples the microwave beam to the SCW. The microwave power emerging from the waveguide is scanned in the far-field region using calibrated detectors. The power spectrum at the output of the SCW shows that the peak appears at the same angle input to the SCW. Effective steering is achieved for a smaller length of the waveguide at various input angles from 6 deg to 18 deg.
