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.

The results of the bulk material examinations performed on samples from the Three Mile Island Unit 2 (TMI-2) reactor pressure vessel (RPV) are summarized and the materials chemistry that resulted in the observed behavior is reviewed. As part of the TMI-2 core examination program, core material samples from all regions within the RPV were examined, from lead screws in the top head to previously molten material relocated to the lower plenum of the RPV during the accident. These results indicate that >99% of the core materials were retained within the RPV; however, the constituents of the various core components were redistributed within the original core volume and RPV. The data suggest redistribution of the core materials based mostly on the thermodynamic properties of the metallic constituents and oxides.
