Effect of sodium pool temperature on grapple drive stem temperatures at seals in CRBRP IVTM
The effect of sodium pool temperature on the grapple drive stem temperatures at the seals of the CRBRP (Clinch River Breeder Reactor Plant) IVTM (In-Vessel Transfer Machine) has been calculated. Reducing the sodium pool temperature from 500 to 400/sup 0/F reduces the maximum grapple drive stem temperature at the seals from 510 to 472/sup 0/F on the initial up-stroke, and from 285 to 225/sup 0/F when system is at dynamic thermal equilibrium. The time the stem can remain in lowered position without stem temperature exceeding 300/sup 0/F at seals when stem is raised, increases from 4 minutes to 20 minutes, (the system being initially at dynamic thermal equilibrium).
