ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Colin Judge: Testing structural materials in Idaho’s newest hot cell facility
Idaho National Laboratory’s newest facility—the Sample Preparation Laboratory (SPL)—sits across the road from the Hot Fuel Examination Facility (HFEF), which started operating in 1975. SPL will host the first new hot cells at INL’s Materials and Fuels Complex (MFC) in 50 years, giving INL researchers and partners new flexibility to test the structural properties of irradiated materials fresh from the Advanced Test Reactor (ATR) or from a partner’s facility.
Materials meant to withstand extreme conditions in fission or fusion power plants must be tested under similar conditions and pushed past their breaking points so performance and limitations can be understood and improved. Once irradiated, materials samples can be cut down to size in SPL and packaged for testing in other facilities at INL or other national laboratories, commercial labs, or universities. But they can also be subjected to extreme thermal or corrosive conditions and mechanical testing right in SPL, explains Colin Judge, who, as INL’s division director for nuclear materials performance, oversees SPL and other facilities at the MFC.
SPL won’t go “hot” until January 2026, but Judge spoke with NN staff writer Susan Gallier about its capabilities as his team was moving instruments into the new facility.
Advanced Reactor Safety (ARS) SPeaker
Anders Gilbertson (preferred pronouns he/him/his) started work at the U.S. Nuclear Regulatory Commission in 2009 and served as a Reliability and Risk Analyst until 2022 when he became a Senior Project Manager in the Office of Nuclear Reactor Regulation, Division of Advanced Reactors and Non-Power Production Utilization Facilities.
Prior to starting with the NRC, Anders earned a Bachelor’s degree in physics and astronomy in 2002 and a Master’s degree in nuclear engineering in 2009, both from the University of Maryland, College Park. Since working at the NRC, Anders has been involved in several high-profile, risk-related projects as a lead for the development team for the NRC’s trial Regulatory Guide on PRA acceptability for non-LWR reactors, Regulatory Guide 1.247, and the lead for the development of other key risk-informed NRC regulatory guide revisions related to PRA acceptability for LWRs, Regulatory Guide 1.200, and risk-informed licensing basis changes for LWRs, Regulatory Guide 1.174. Anders was the Technical Lead for the Other Hazards Evaluation under the NRC’s Level 3 PRA Project and supported the development of the Level 2 PRA model for that project. More recently, Anders supported the development of guidance on construction permit PRA acceptability published in RG 1.253, Revision 0. When not working, Anders enjoys spending as much time with his family as he can, rock climbing, and motorsports.
