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
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.

Kathryn Huff stepping down from DOE Nuclear Energy post
Huff
After serving two years as the Department of Energy’s assistant secretary for Nuclear Energy, Kathryn Huff will vacate that position on May 3 and return to teaching. Huff had started at the DOE in May 2021, serving for one year as the principal deputy assistant secretary for Nuclear Energy
“Serving in this capacity has been an unparalleled privilege, and I’m immensely grateful for the opportunity to have worked alongside you--the dedicated and talented public servants in Nuclear Energy, in DOE, and across the Biden-Harris Administration,” Huff wrote in an email announcement to colleagues last week. “I chose this timing to enable the smoothest transition back to my professorship at the University of Illinois at Urbana-Champaign where my beloved research, students, husband, and dog await.”

The US/Japan collaboration (Japan-US Program of Irradiation Tests for Fusion Research: JUPITER) has been effective in accumulating an irradiation database and in understanding the mechanism of irradiation effects of reduced activation ferritic steels (RAFS). The irradiation data obtained up to now indicates rather high feasibility of ferritic steel for application to fusion reactors, because of their high resistance to degradation of material performance by both the displacement damage and helium. The martensitic structure of the RAFS consists of a kind of lattice defects before the irradiation, such as dislocations, lath boundaries, precipitates and carbides, which strongly reinforce the resistance to displacement damages through absorption and annihilation of the point defects generated by the irradiation. Transmutation helium can be trapped at those defects in the martensitic structure so that the formation of helium clusters at grain boundaries, which causes intergranular embrittlement, is suppressed. The martensitic structure of the RAFS is considered to be appropriate for fusion structural material. Efforts to increase high temperature strength have been made for RAFS.
