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.

Bulgaria's Kozloduy plant switching to Westinghouse fuel
Bulgarian officials have approved the transition to Westinghouse fuel at the nation's Kozloduy nuclear power plant, as Bulgaria moves away from its reliance on Russian supplies. The fuel was recently delivered for use in Unit 5.

In this experiment, Type 316L stainless steel rods were fabricated through laser additive manufacturing (LAM) in three different orientations, and microstructural and mechanical changes induced by high dose ion irradiation were characterized based on orientation. The rods were irradiated with Fe2+ self-ions to a peak dose of 80 displacements per atom at 475°C. Results were compared to concurrently irradiated conventionally manufactured control specimens. Electron backscatter diffraction of the rods yielded statistically relevant information related to grain microstructure and texture. Transmission electron microscopy revealed a high density of elongated radiation-produced defects in the LAM specimens that were aligned with the major axes of the defects parallel to the build direction. Mechanical testing of LAM rods revealed anisotropic radiation-induced hardening, where hardening is greatest perpendicular to the build direction and least parallel to the build direction. Several radiation-induced hardening phenomena are considered that contribute to the observed anisotropic strengthening.
