EVENT DESCRIPTION AND PROBABLE CONSEQUENCt3 h I o 12 I l While operating at less than 2% thermal power, during regeneration of a batch of con- 1 ITTTl I densate polisher resin, waste water was discharged to the plant liquid effluent sys- l lo14l l tem rather than the waste neutralizing tank. As a result, the pH limits of Fort St. I loIsi lVrain Technical Specification LCO NR 1.1 was exceeded. This is reportable per l l 016 l l AC 7.5.2(b)2. No effect on public health or safety.
