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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The NCSU electrothermal plasma gun, SIRENS, has been used to evaluate the erosion behavior of plasma-facing components under conditions simulating plasma disruption in tokamaks. The device is capable of producing conditions with heat fluence up to 10 MJ/m2 over 0.1 and 0.25 ms pulse duration. In future large tokamaks, plasma-facing components are expected to receive heat fluxes during a plasma disruption, which may exceed 100 GW/m2 over 0.01–5 ms. The vapor, which is developed at the ablating surface, absorbs a fraction of the incoming plasma energy. Candidate plasma-facing materials have been exposed to heat fluxes in the SIRENS facility (primarily from a blackbody spectrum photons), up to 100 GW/m2 over 0.1–0.25 ms. The vapor shielding effect has been demonstrated and analyzed for the divertor candidate materials.
