1 gl High vessel conductivity was caused by high conductivity condensate in the heater l i i l drains system being concentrated in the vessel. Forward pumping to the vessel of  ;

heater drains condensate was reduced until its conductivity was lowered, and Nn'CU g i ., l 2

gl was used to reduce vessel conductivity to less than 2 umhos/cm . This is considered; i 4 l to be an isolated event and no further action is required. l 30 7 8 9
