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.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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 fixed-bed adsorption processusing zeolite has been studied as one of the promising processes for the recovery of tritiated water in the field of nuclear fusion. In H2O-HTO binary systems, the difference in adsorption rate must be considered to obtain the isotopic distribution coefficient of tritiated water adsorbed on zeolite. The static method is probably the best approach to measure the distribution coefficient considering the difference in adsorption rate. In this study, the influence of framework SiO2/Al2O3 ratio ranging from 2.0 to 10.0 and of cations (K+, Na+, Ca2+) on isotopic distribution coefficient of tritiated water adsorbed on faujasite-type zeolite was systematically examined. The isotopic distribution coefficient of tritiated water between water adsorbed on zeolite absorbent was 1.1~1.4. The effect of framework SiO2 to Al2O3 ratio of the X/Y type zeolite on the isotopic distribution coefficient depended on the content of cation in zeolite. The framework SiO2 to Al2O3 ratio of the NaX/NaY zeolite had negligible effect on the isotopic distribution coefficient. The considerable effect of framework SiO2 to Al2O3 ratio was found in the case of KX/KY and CaX/CaY zeolite.
