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.

Following the Fukushima accident, research of accident tolerant fuel (ATF) and cladding materials began in order to improve the nuclear power plant safety following a Beyond Design Basis Accident (BDBA). National laboratories, industry, and universities are involved in this activity. Researchers at the University of Wisconsin are simulating BDBA’s to examine the effect of ATF cladding material using MELCOR. Use of alternate cladding materials (FeCrAl) and potential operator recovery actions have been previously studied. In this work, we examine the effect of FeCrAl coating on Zircaloy using a special version of MELCOR-1.8.6 (YU) developed by Idaho National Laboratory. This MELCOR version allows one to examine the effect of cladding coatings (Cr, FeCrAl) assuming appropriate thermo-physical data are available. FeCrAl is used as a first application of this modeling approach for clad coatings. Using a Short- Term Station Blackout (STSBO accident sequence shows that overall accident progression is quite similar to events without a coating, except for the start rapid core heatup, degradation and significant hydrogen generation. These events are delayed for more than an hour compared to nominal conditions.
