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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

An eddy-current flowmeter (ECFM), designed to measure the velocity of coolant sodium exiting the fuel subassemblies of the Fast Flux Test Facility (FFTF) to be built at Richland, Washington, was tested in the Westinghouse Advanced Reactors Division’s General Purpose Loop No. 2 (GPL-2) during the period of October 2, 1971 to March 16, 1972. The ECFM was operated in both a wet and dry prototypic (FFTF) design test housing. In the wet design test housing, the ECFM is exposed directly to sodium; in the dry design test housing, the ECFM is shielded from sodium by a stainless-steel “thimble.” During both tests, the same ECFM electronics supply and associated wiring were used. The same ECFM electrical adjustments also were employed in both cases. Throughout the total testing period of 1351.6 h, the ECFM operated satisfactorily. No failures or malfunctions occurred in the ECFM, its power supply, or the three test thermocouples. Significantly, the data showed that the ECFM’s overall average dc output signal in the dry design was 62% of that in the wet design.
