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.

A three-dimensional pipe element, with eight degrees-of-freedom per node, is developed to consider the stresses arising from the pipe internal pressurization as well as the stresses arising from the three-dimensional flexural motion of the piping system. The scheme is developed for coupling with piping hydrodynamics so that a realistic safety assessment of a reactor’s piping system can be achieved. Using rigid co-rotational coordinates, the finite element formulation is suited for large displacement but small strain situations. Both geometric and material nonlinearities are considered. The equations of motion are integrated by an explicit procedure. Sample results are presented to demonstrate the performance of the element in its individual as well as coupled modes of deformation.
