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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

The foundation of the Versatile Economic Risk Tool is based on the methodologies of the Generation Risk Assessment (GRA) and uses a systematic approach to prioritizing systems, structures, and components based on estimated operation reliability and the impact on future power generation. The GRA provides management with insight that helps with decisions on maintenance, component repair/replacement, design modifications, and other issues associated with electricity generation and equipment reliability programs. Although the benefit of the GRA is understood in the nuclear community, there are negative aspects associated with the current approaches. Traditional GRA modeling is time consuming, convoluted, and considers only the static portion of generation risks. The Versatile Economic Risk Tool addresses the drawbacks of the traditional GRA through simplifying and/or automating the requirements for an effective GRA model. The Versatile Economic Risk Tool also integrates in-depth parametric variability within models to evaluate system, structure, and component generation risks as a function of time. The Versatile Economic Risk Tool addresses the shortcomings of the GRA by automating the study of equipment reliability and degradation from an electricity generation perspective by coupling fault tree analysis and statistical analysis software that support repetitive, parametric analyses. Versatile Economic Risk Tool case studies are presented to provide insight into the potential benefit provided.
