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.

Take steps on SNF and HLW disposal
Matt Bowen
With a new administration and Congress, it is time once again to ponder what will happen—if anything—on U.S. spent nuclear fuel and high-level waste management policy over the next few years. One element of the forthcoming discussion seems clear: The executive and legislative branches are eager to talk about recycling commercial SNF. Whatever the merits of doing so, it does not obviate the need for one or more facilities for disposal of remaining long-lived radionuclides. For that reason, making progress on U.S. disposal capabilities remains urgent, lest the associated radionuclide inventories simply be left for future generations to deal with.
In March, Rick Perry, who was secretary of energy during President Trump’s first administration, observed that during his tenure at the Department of Energy it became clear to him that any plan to move SNF “required some practical consent of the receiving state and local community.”1

As one of the key components in tokamak fusion reactor, the divertor is often exposed to tritium environment, high heat flux, and neutron radiation which are harmful for human beings and the divertor itself, which is damaged easily. So maintenance for the divertor is necessary. However, due to neutron damage and activation, maintenance for the divertor should be done in a remote way rather than by personnel directly, especially the process for installing the divertor into the inner and outer rails in the vacuum vessel from the outside. As an important compatible structure for the divertor remote handling (RH) process, inner and outer supports should be considered for ensuring the RH process goes well. Thus this paper introduces the China Fusion Engineering Test Reactor divertor support design mechanism, including inner support and outer support, which are based on the requirements of RH. Then the electromagnetic forces generated by Halo current and Eddy current due to plasma disruption are analyzed in order to validate the design of the newly designed support mechanism.
