Flow Components in a NaK Test Loop Designed to Simulate Conditions in a Nuclear Surface Power Reactor

摘要: A test loop using NaK as the working fluid is presently in use to study material compatibility effects on various components that comprise a possible nuclear reactor design for lunar surface. DC electromagnetic (EM) pump has been designed and implemented means of actively controlling flow rate through system an EM sensor employed monitor developed rate. These allow matching conditions loops with those would be found full‐scale surface‐power reactor. The operating characteristics are presented. In pump, current applied set electrodes produce Lorentz body force fluid. measurement induced voltage (back‐EMF) provides monitoring Both compact, employing high magnetic field strength neodymium magnets thermally coupled water‐cooled housing. vacuum gap limits h...
