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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

BREAKING NEWS: Trump issues executive orders to overhaul nuclear industry
The Trump administration issued four executive orders today aimed at boosting domestic nuclear deployment ahead of significant growth in projected energy demand in the coming decades.
During a live signing in the Oval Office, President Donald Trump called nuclear “a hot industry,” adding, “It’s a brilliant industry. [But] you’ve got to do it right. It’s become very safe and environmental.”

A high fidelity wall-resolved Large Eddy Simulation has been performed for the flow through a guide plate of a Control Rod Guide Assembly (CRGA) at a hydraulic Reynolds number of 10,000. The computational mesh contains more than 1 billion computational cells and the simulation is run over six flow passes, which corresponds to almost 1 million time steps. The pressure forces are computed for all the rods and their average and rms values analyzed. This simulation can be either used to validate coarser LES/URANS computations, to understand the origin of physical phenomena such as deformations and vibrations or to model the pressure load along a rod.
