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
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

Gamma-ray heating rates from 60Co and 137Cs are measured independently in a stainless steel sphere using thermoluminescent dosimeters (TLDs) with different sensitivities and atomic numbers, a useful check on dosimetric measurements. Gamma-ray dose-weighting f factors, based on the general cavity ionization theory, are applied to convert the net TLD dose rates into gamma-ray heating rates in stainless steel. Gamma-ray spectra are calculated using the ANISN computer code together with the DLC-41/VITAMINC cross-section library. The experimental and the calculated gamma-ray heating rates are compared. The calculation-to-experiment (C/E) ratios of the heating rates are close to unity at experimental positions near the gamma-ray source and show drop-off at far positions. This C/E discrepancy comes primarily from the calculations; however, there is a minor contribution to the C/E discrepancy from the TLD overresponse at low gamma energies.
