CHLORINE MONITORING DATA D. C. COOK NUCLEAR PLANT UNIT NO. 1 DOCKET NO. 50-315

1. Chlorination is normally on a twice per day automatic program. Each period of chlorination consists of five minutes of system operation (chlorine injection water supply pump running) to establish a vacuum, twenty minutes of chlorine injection, and the last five minutes for system flushing, for a total chlorination program of thi'rty minutes.

These programs are scheduled to begin twelve hours apart. Each period of chlorination is sampled at the condenser outlet water box at five minute intervals until a zero total chlorine residual is seen or the program ended. The only system treated thus far has been the unit I main condenser.

2. Total chlorine residual analysis is done by the amperimetric titration method.

3. The instrument which is used and the concentration of reagents gives a sensitivity of 0.03 ppm total chlorine residual.

4. A. Continuous unit chlorination was begun in February 1975.

B. No additional methods are used to maintain condenser cleanliness.

few minor equipment problems have occurred such as leaks, heater C. A failures, and electrical equipment failures, however, in 'spi redundancy in the system few complete system outages have been te'f the encountered.

5. In the attached list of chlorination the times given are start time of the chlorination program. Samples were taken as described in number I above. The total chlorine residuals reported are at the condenser outlet water box. It has been shown in tests that the, actual concentration at the discharge in the lake at a point which is inhabitable by fish is on the order of 50Ã of the value at the condenser outlet water boxes.
