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.

Teenager’s school project achieves plasma
Cesare Mencarini’s recent extended project qualification (EPQ) earned him an “A” for his studies in the United Kingdom—and became, it is believed, to be the first nuclear reactor built in a school environment.

Dynamic behavior of cryogenic distillation columns has been studied with an H-D-T system (1.5 g of tritium) under single column and two-column cascade operation modes. The columns used were different in inner diameters (1 cm and 2 cm) and in size packings (3 mm Dixon rings for the larger column and 1.5 mm Dixon rings for the smaller column). For both of the columns, the experimental observations for composition distribution at the steady-state was in close agreement with calculated results for all the components. The HETP values measured were in the range from 3 to 6 cm. The dynamic variations of compositions in bottom product streams experimentally observed were well predicted by computer-aided simulation. For top product streams, the variations were significantly slow in comparison with those of the calculated results using an assumption that liquid holdups in condensers were negligible. These results indicate that the columns have appreciable liquid holdups at the condensers.
