_EVENT DESCRIPTION AND PROBABLE CONSEQUENCES@

[IJIJ I Steam generator chemistry e~ceeded TS 3.18 pH lower limit* 9f* 8.2 when condensate polishers were placed in service to control water chemistry during a condenser in-leakage.

Chemical additions were initiated to increase pH resulting in steam generator pH and conductivity upper limits I being exceeded on June 4, 1979 and June 5, 1979. No threat to Public [IJIJ I health or safety existed.

44 47 rr:TIJ I The pH drop was caused by resin leakage from the condensate polishers due I to defective septums.

A subsequent over addition of morpholine raised pH and conductivity to out of spec levels.

Chemistry was _brought under EII1J I control by changing the resin mixture and terminating chemical feed.
