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.

Constellation seeks rezone for property adjacent to Illinois plant
While no development details have been released, Constellation is asking to rezone 658.8 acres of land it owns around the Byron nuclear plant in Illinois for possible long-term use.

This paper reports the results of the high-power tests of a remote-steering-launcher mock-up at 140 GHz, which were performed at the electron cyclotron resonance heating installation for the future stellarator Wendelstein 7-X (W7-X) at Max-Planck-Institut für Plasmaphysik, Greifswald. The mock-up test system consists of a 6.62-m-long square corrugated waveguide with a steerable optic at the entrance and various diagnostics at the exit of the waveguide. A straight launcher and a version with two integrated miter bends were investigated.The ohmic loss of the waveguide was measured via the temperature increase of the waveguide wall and was used to calibrate the calculated angular dependence of the total ohmic losses of the waveguide. Short-pulse radiation pattern measurements with thermographic recording show high beam quality and confirm the steering range of -12...12 deg. The version with two miter bends produces similar results but with an increased level of side lobes.Although the tests were performed under atmospheric pressure, no arcing was observed in the straight waveguide. In the version with the miter bends, however, arcing limited the power and pulse length.
