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.

IEA report: Challenges need to be resolved to support global nuclear energy growth
The International Energy Agency published a new report this month outlining how continued innovation, government support, and new business models can unleash nuclear power expansion worldwide.
The Path to a New Era for Nuclear Energy report “reviews the status of nuclear energy around the world and explores risks related to policies, construction, and financing.”

The influence of the port void on the thermal-neutron scalar flux at the source plane and on the current at the exit plane of a beam port is examined experimentally and analytically. Activation experiments on 1 1/2, 3-, and 5-in. diam ports inserted into the water and graphite reflectors of a swimming-pool reactor are compared with an elementary P1 analysis. The exit current is found to be well-predicted by the theory, which depends only upon a knowledge of the scalar-flux distribution when the beam port is absent.
