Endurance test of prototype test loop for evaluation of refractory alloys in boiling and condensing potassium environments simulating space electric power systems
Friction and wear resistant alloy materials for potassium lubricated journal bearings and shafts
Refractory alloy corrosion, discussing columbium and tantalum base tubing alloy resistance to refluxing potassium between 1800 and 2400 degrees F
Thermionic energy converter converts nuclear generated heat directly into high frequency and direct current output. It consists of a potassium plasma cell, a tantalum emitter, and a silver plated copper collector. This conversion process eliminates the steam interface usually required between the atomic heat source and the electrical conversion system.
