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.

Here is a recap of industry happenings from the recent past:
Last Energy forms partnership with NATO center
The NATO Energy Security Center of Excellence (ENSEC COE), located in Vilnius, Lithuania, and Washington, D.C.–based Last Energy have formed a partnership to investigate military applications for microreactor technologies. The agreement was ENSEC COE’s first with a company in the nuclear energy sector. Last Energy, which is a spin-off of the research institute Energy Impact Center, will conduct research with ENSEC COE on microreactor applications for NATO military installations, explore opportunities for deploying microreactors on NATO bases, and serve as an industry advisor to ENSEC COE. Last Energy’s PWR-20 small modular reactor is a pressurized water reactor with a capacity of 20 MWe (60 MWt). It is designed to be built off-site and assembled in modules within a period of 24 months.

A 106-GHz electron cyclotron heating system is installed and operated for plasma production and heating of the Heliotron-E helical device. The Gaussian beam radiated from the gyrotron is coupled to the HE11 waveguide mode by the matching optics unit (MOU), then transmitted through 15-m corrugated waveguides and four miter bends. The system is closed for safety to prevent spurious modes from radiating into the free space and is operated at atmospheric pressure. The transmitted wave is launched from the outside of the torus, and the launched beam is focused on the magnetic axis so that the power deposition is expected to be localized at the desired resonance region. The measured transmission efficiency from the MOU output to the launcher output is 86%, which is in good agreement with the theoretical estimate. The power losses arise mainly at the waveguide mouth where the Gaussian beam is coupled to the HE11 mode, at the miter bends and in the launching system.
