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.

The measurement of the amount of impurities in tritiated gases can be achieved by means of mass spectrometry or gas phase chromatography.A growing number of disadvantages associated to the "life expectancy" of the mass spectrometer and its tricky maintenance (when enclosed in a gloves box) have led us to acquire a micro gas phase chromatograph. This device is based on a modular concept with the injector, the column and the detector packed in a compact unit which is easy to replace. Thanks to constant improvement in the field of capillary column, new micro chromatographs are now able to perform measurement in absence of pre-column and presence of argon instead of nitrogen as a carrier gas. Of importance, this new apparatus allow better performances (running time: 1 m 30 sec, limit of detection: < 10 ppm).However, in normal use, this apparatus requires 800 millibar in the inlet, a pressure that doesn't match with the feature of our process gas. To overcome this inconvenience, we have developed an automatic functioning system with a bellows that samples and compresses the gas to pressures compatible with the micro gas chromatograph.The apparatus and the experimental procedures will be presented as well as experimental performances (reproducibility, detection limits. . .) for some impurities such as nitrogen, oxygen and helium.
