Development Status of the LMCD-II Potassium Cooled Inductor Generator
The configuration and design features of a potassium cooled 50 kw model (LMCD-II) generator are described, including the stator bore seal, bearing and shaft seal configuration, and cooling path arrangement. The unique fabrication techniques discussed include precision machining of the rotor, joining of components by electron beam welding, and assembly of the ceramic-glass insulation system. Results of tests both in conventional fluids and liquid potassium are compared with calculated performance. The problems encountered and the areas requiring further development are presented. Finally, the requirements anticipated for the integration of a generator with the power conversion portion of the SNAP-50/SPUR system are discussed.
