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.

Fast-neutran irradiations in the EBR-II have been completed an biaxial stress rupture, creep, and tensile specimens of AISI 304 and 316 stainless steel. Postirradiation test results show that irradiations in the 480 to 650°C range to fluences of 1 × 1022 n/cm2 (E > 0.1 MeV) substantially reduce the time-dependent rupture life and ductility of these materials. Tensile ductility is also severely reduced. Bulk-density measurements and electron-microscopy examinations on specimens of annealed 304 from EBR-II core components and mechanical property specimens have been made for fluence levels to 7 × 1022 n/cm2 and at temperatures in the 360 to 470°C range. Both the bulk-density measurements and microscopy examinations correlate well and indicate that volume changes of 4% can be expected under these conditions. The temperature and fluence dependency for annealed 304 stainless steel has been determined and can be expressed as: The mechanisms responsible for the observed degradation of mechanical properties and metal swelling are being studied. Some observatians are presented. However, as yet, no adequate nucleatian and growth model has been determined to enable an acceptable extrapolatian of these data-to-goal fluence levels to be achieved in Liquid Metal Fast Breeder Reactor core companents or fuel-pin cladding.
