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.

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.”

Dose buildup factors for normally incident 662-keV gamma rays penetrating multilayered aluminum-lead slabs were measured for various combinations using thermoluminescence dosimeters. The results were compared with calculated values obtained from a gamma-ray transport code and with values inferred from a semiempirical formula using single-layer slab buildup factors. This formula, a slightly modified version of the Kalos formula, predicts buildup factors in excellent agreement with both experiments and calculations, even for multilayered combinations. The formula also provides buildup factors which are in good agreement with transport calculations for other source energies and slab materials, indicating a probable wide range of validity.
