l i l o l l Normal CST water usage during plant startup and turbine testine. coincident with do- l li j i l lmineralizer regeneration, caused the CST level to no below the T.S. limit. I lij7l l The S/C blowdown rate was reduced until the demineralizer was back in service and the I gg l CST level was returned to normal. A T.S. proposed revision has been submitted l 3 . l (2-20-81) to permit the CST level to drop below 75,000 gallons during plant startup.
