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.
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.

In a liquid blanket system, MHD effect or low heat-transfer property of high Prandtl number fluid makes it difficult to remove high heat load, therefore utilization of ducts with inserted rods or sphere-packed pipes has been proposed to enhance the heat transfer. It is important to reveal influence of arrangement of the rods or spheres upon the heat transfer characteristics. In this study, the influence of a distance between two rods in wall-normal and streamwise directions upon the flow structures is clarified by numerical simulation. When the rod is approaching to another rod in the wall-normal direction, Karman's vortex street is disrupted. On the other hand, the distance between the rod and the wall is shorter than a certain value, a separation occurs on the wall and then the separation position does not move when the distance is much smaller than that value. Moreover, the pressure drop depends on the distance between two rods, and then there exists the minimum pressure drop. When the distance between the two rods becomes shorter in the streamwise direction, the wake behind the upstream rod changes from Karman's vortex street to twin vortexes and the pressure drop decreases. The turbulent kinetic energy near the wall in case of Karman's vortex street, which is generated by the upstream rod, is higher than that in case of twin vortex.
