Brazed thermocouple pass-through for sodium service in a liquid-metal- cooled fast breeder reactor
Conference
·
OSTI ID:4159067
Sensors installed in special fuel elements for the EBR-II reactor had 30- ft-long leads that would pass from the sodium environment through a sealed bulkhead. A hydrogen-atmosphere, induction-heated brazing furnace was constructed to simultaneously braze 20-26 separate sensor leads at one time. The brazed seals were leak-tight, and the sheath wall has less than 10 percent interaction with the braze alloy. (auth)
