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 updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

This research reveals the results of a thermo-mechanical stress analysis of the beryllium and CuCrZr components of the Enhanced Heat Flux (EHF) First Wall (FW). Under the EHF thermal load, differential thermal expansion at the Be/CuCrZr interface can potentially lead to failure of the beryllium tiles. We have shown that the stress profile in both beryllium and CuCrZr can be improved by reducing the dimensions of the beryllium tiles covering the FW panels.In addition, our research investigated a failure condition for the FW finger's design. Specifically, we assessed the temperature profile at the CuCrZr/water interface of the EHF FW finger in the event of a single failed tile. This was done in order to determine whether or not the critical heat flux condition occurs in the coolant channel after a single tile failure. Assuming the failure of a single tile between 11.75mm and 50mm in size, temperature profiles were generated assuming flat, rectangular water cooling channels. It was found that tile failure from the edges of the finger resulted in considerably higher temperatures than tile failures at the middle of the finger. Failure of a tile along the edge of the finger may cause catastrophic failure, as the critical heat flux condition occurred at the CuCrZr/water interface even for tiles as small as 11.75mm in size.
