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.”

Two-group integral neutron capture cross sections have been measured for 144Sm and 145Sm. Mass spectrographic assays were carried out on highly enriched samples of 144Sm that were irradiated in a high-flux nuclear reactor making use of cadmium filters and cobalt as a flux monitor. Under the assumption that these nuclides have a (1/ν) dependence in the thermal region, the following are reported: for 144Sm, σc2200 = 1.64 ± 0.10 and Ic = 2.38 ± 0.17 b; for 145Sm, σc2200 = 280 ± 21 and Ic = 600 ± 90 b.
