Neutron Imaging Of Lithium Inside A High-Temperature Heat Pipe, Eric Henry Kirchoff
Neutron Imaging Of Lithium Inside A High-Temperature Heat Pipe, Eric Henry Kirchoff
Masters Theses
Neutron imaging of a high-temperature Mo-Li [molybdenum-lithium] heat pipe has been performed to assess Li flow visualization. The high neutron attenuation cross section of Li allows for imaging inside the heat pipe shell structure, which has a lower value of neutron attenuation, making neutron radiography an ideal choice for characterizing Li movement.
The gravity assisted, cylindrical heat pipe was heated to 903oC [degree] using a wire resistance Mo heater operating under vacuum. This Mo-Li heat pipe is 35 cm long with a square internal geometry 2.2 cm per side, utilizing small corner radii as the wicking structure for …
