CA0108181) . A smmary of the generating unit's status aM significant analytical results is provided below.

The unit was in operation during April. All sampled water sources were fouM to be within permit limits. On April 24, 1988, the circulating watar delta tanperature exceeded the daily average allowed by one degree.

This occurred due to a series of unusual coMitions. A heat treat:nent was in progreso on Unit 2 incitxling the Unit 2 saltwater coolia) discharge

" line, which was lined up to discharge to the Unit 3 intake. '!his lineup caused the delta temperature to increase. Although prompt action was taken to reduce power, limits on th.. Late of power reduction were such that it was not possfble to inmediately reduce the averaga temperature rise to less than 23 F without shutting the unit down. To avoid this problem in the future, we have initiated operating procedure changes.
