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 single quartz crystal microbalance (QCM) is cooled to 18 K to measure condensation rates inside of a retractable shroud enclosure. The shroud is designed to minimize condensate on fusion targets to be fielded at the National Ignition Facility (NIF). The shroud has a double-walled construction with an inner wall that may be cooled to 75 to 100 K.The QCM and the shroud system were mounted in a vacuum chamber and cooled using a cryocooler. Condensation rates were measured at various vacuum levels and compositions and with the shroud open or closed. A technique for measuring total condensate during the cooldown of the system with an accuracy of >1 × 10-6 g/cm2 was also demonstrated. The technique involves a separate measurement of the condensate-free crystal frequency as a function of temperature that is compared to the measurement for the cooldown trend of interest. The shroud significantly reduces the condensation rates of all gases and effectively eliminates H2O condensation.
