2.0 ENVIRONMENTAL PROTECTION CONDITION Requirements of 2.1.1 and 2.1.2 (Temperature Limitations) and 2.3 (Chemical Analyses and Chemical Use Report) have been met as demonstrated by Table 1,

  • Tabic 2, and the following summary.

2.1.1 Maximum AT Across the Condenser Limitations for condenser AT have been met. During January, February, and March all temperatures above the 18 F limitation were during periods of deicing; there-fore, the temperatures were within applicable limits.

During June the AT values that exceeded the 18 F limitation were during periods of backwashing, however, the 30 F limitation was not exceeded; therefore, temperatures experienced in June were within applicable limits.

Effective June 24, 1980, the Environmental Technical Specifications 2.1.1/3.1.1, Maximum AT Across the Condenser were deleted by License Amendment 63, Cooper Nuclear Station (NRC Docket No. 50-298, DPE-46).

2.1.2 Maximum Discharge Temperature The maximum discharge temperature limit of 103 F was exceeded for various periods of time on seven separate days in 1980. Each of the dates and the maximum .

temperatures are listed as follows:

July 9, 1980 104.5 F July 10, 1980 105.00F July 11, 1980 105.0 F July 12, 1980 104.5 F July 14, 1980 104.00F July 15, 1980 104.5 F July 16, 1980 104.00F The 1030F maximum discharge temperature limit is based on a rivet temperature of 85 F and the Missouri River Temperature exceeded this value by several degrees during the month of July. Effective November 13, 1980, the Environmental Technical Specifications 2.1.2/3.1.2, Maximum Discharge Temperature were deleted by License Amendment 65, Cooper Nuclear Station (NRC Docket No. 50-298, DPR-46).

Table 1 is a summary of monthly maximum outlet temperatures and maximum condenser AT's for the appropriate periods that the Environmental Technical Specifications (ETS) were in effect. As noted above, ETS 2.1.1/ 3.1.1 Maximum AT Across the Condenser were deleted effective June 24, 1980; therefore, no values are reported af ter that date. Also ETS 2.1.2/3.1.2, Maximum Discharge Temperature were deleted effective November 13, 1980 and no values are reported following that date.

2.3 Chemical Chemical Analyses River water samples were collected by plant personnel and analyzed monthly from January through December at the river water intake and the discharge canal of Cooper Nuclear Station.

Analyses for turbidity, specific conductance, chlorine, copper, iron, potassium, sodium and pH were conducted by plant personnel as specified in the Cooper N2 clear Station Enviror. mental Technical Specifications (ETS).

Turbidity and specific conductance values in tne discharge canal were always within the ETS limit . tion of less than 10% greater than tne inlet values.

Total chlorine concentration in the discharge canal was less than 0.03 mg/l and, therefore, did not exceed the ETS maximum criterion of 0.1 mg/1.

Concentrations of copper, iron, potassium, and sodium in the discharge canal did not indicate any substantial increase due to plant operation.

The analyses for pH at the inlet and the discharge canal were well within the ETS limitations of 6.5 to 9.0 pH.

The limitations of the above mentioned parameters were not exceeded at any time, e therefore, there has not been any significant chemical affect on the Missouri River water due to plant operation in 1930. 3 s
