ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

For the purpose of developing a cryogenic pressure swing adsorption (PSA) system, we have been studying the breakthrough behavior of hydrogen isotopes with synthetic zeolite packed-beds under conditions specified for designing a PSA process. Previously, we have reported that overshooting breakthrough curves of tracer D2 in H2 were obtained from experiments of exchange-adsorption carried out after replenishing a packed-bed column with H2 from its outlet, following evacuation for a given period. The overshooting behavior is considered due to the enrichment of the heavier component D2 not only in the adsorption process but also in the evacuation process. In the next work, we have examined the effects of priming flow rates and evacuation periods on the overshooting behavior, using synthetic zeolites 5A and 13X packed-bed columns. In this paper, it is reported that the overshooting profile depends on the conditions of evacuation but not sensitively on the mass flow rates in replenishing process. The overshooting is advantageous for the adsorption process, because of improvement of the breakthrough time. Since the replenishing period is shortened proportionally to the priming flow late, the insensitive dependence of the overshooting on the priming flow rate is favorable to the PSA process, resulting in saving the time for replenishing process.
