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.

Atomic Museum marks 20 years of education
The National Atomic Testing Museum, better known as the Atomic Museum, is celebrating its 20th anniversary this year. Located in Las Vegas, Nev., the museum was established in 2005 to preserve the legacy of the Nevada Test Site, now called the Nevada National Security Sites.

Safety analysis of fast reactors requires knowledge of the vapor pressure of the fuel material under the condition of rapid heating in the temperature region from 3000 K upwards, where up to now no measured data have been available. An experimental technique to determine the vapor pressure of refractory fuel materials in the temperature range between 3000 and 5000 K is based on laser beam heating of the specimen surface for ∼1 msec and measurement of both the recoil momentum of the specimen and the mass and momentum carried away by the vapor jet flowing into a vacuum. The determination of the vapor pressure requires application of gas dynamics and development of a suitable mode. The application limits of such a measuring technique using laser heating and the reliability of the vapor pressure data thereby determined have been assessed.
