The Experimental Breeder Reactor 2 (EBR-2) is a sodium-cooled nuclear reactor with thermal and electrical outputs of 62 and 20 megawatts, respectively. EBR-2 has plugging temperature indicators (PTIs) in the sodium coolant system to measure the temperature that impurities will precipitate from the coolant. High plugging temperatures are undesirable because impurities can precipitate in cold reactor piping and inhibit sodium flow. Reading a plugging temperature accurately from a typical plugging run is important. A computer simulation program performs simulated plugging runs to optimize PTI operation. The simulation program also assisted electrical engineers in designing and testing a new PTI control …
