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
Accelerator Applications
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.

The structure of the catalyst used in a passive autocatalytic recombiner (PAR) is crucial for making the PAR reliably functional in environments of high humidity and for concentrations of hydrogen above 8 to 10 vol %. The temperature of the catalyst has to be kept below 500°C to avoid the autoignition of hydrogen. A new type of catalyst for the PAR, a hydrophobic catalyst on a low porous metal carrier with a screen [HCm(screen)], was designed by Russian Energy Technologies. It consists of a porous Ti plate with the adsorbtion metal Pt. The surface of the catalyst was completely covered by a metal grid. In a series of tests with different small-scale PARs, the HCm(screen) catalyst was found to function under concentrations of hydrogen up to at least 20 vol %. The effects of mass and heat transfer processes (Fick diffusion, Knudsen diffusion, and Stefan flow) on the thermal regime and characteristics of the working catalyst are discussed. Metal grids of dense weaving appear to be the most suitable for a screen because they have a double function: removing the heat and acting as a gas separation membrane enriching with hydrogen the gas mix in the zone of the catalytic reaction.
