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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Thomson scattering system based on a ruby laser was applied in the GDT to measure the electron temperature during intense neutral beam injection. The system is capable of measuring the radial profile of electron temperature in the midplane over plasma radii varying from 0 to 12 cm. For this purpose the focusing lens is moved from shot to shot along the laser beam. The scattered light condenser with the polychromator is correspondingly rotated. Angle of scattering is in the range of 86–97 degrees. Thomson scattering system enables measurement of the electron temperature at minimal plasma density of ∼1013 cm−3. The time between shots (about 3 minutes) is long enough to collect, store the data and subsequently calculate the electron temperature. In the paper, the data on radial profiles and temporal behaviour of electron temperature during neutral beam heating at GDT are presented. In the experiments, electron temperatures of the target exceeding 100 eV was observed.
