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.

Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

High-purity V-4Cr-4Ti low activation alloy products, such as plates and wires, were fabricated from the NIFS-HEAT-1 ingot with improvements of the conventional manufacturing processes. During fabrication, significant and small increase in hydrogen and oxygen level were observed, respectively. However, these contaminants were released by a heat treatment at 673 K or higher in a vacuum. For the purpose of obtaining an appropriate thermomechanical treatment condition, recrystallization behavior of plate products, which were 6.6, 4.0, 1.9 mm thick, was investigated after cold rolling. It was revealed that annealing at 1273 K for one to two hours provides recrystallized grains of 20-30 μm. Only in the case of 1.9 mm-thick plates which experienced large degree of cross rolling, a layer of finer grain was observed in the vicinity of the surface. The NIFS-HEAT-1 products are going through Round-robin tests by Japanese universities.
