1.0 RADIOACTIVE LIQUID RELEASES Radioactive liquid releases via the circulating water discharge are summarized for total release and by individual source on a monthly basis in Table 1-1. An isotopic breakdown of the total radioactive liquid release is presented in Table 1-2. The total radioactive liquid release excluding tritium for this reporting period was 3.77E-1 Curies which included 2.60E-2 Curies of processed radioactive waste and primary coolant system letdown, 3.40E-1 Curies of Unit 1 steam generator blowdown, 1.10E-2 Curies of Unit 2 steam generator blowdown and 1. 83E-4 Curies of retention pond ef fluent. The total tritium release for Obis reporting period was 436 Curies, which included 428 Curies of processed radioactive waste and primary coolan t system let-down, 5.45 Curies of Unit 1 steam generator blowdown, 1.99 Curies of Unit 2 steam generator blowdown, and 1. 32 Curies of retention pond effluent. All radioactive liquid releases to Lake Michigan were made through the circulating water discharge. 1.1 Additions to Semiannual Monitoring Report January 1, 1979, through June 30, 1979 May J une Total Total Activity Released, Ci Gross Alpha <MDA 8.64E-7 1.50E-6 Average Diluted Discharge Concentration, PCi/cc Gross Alpha 1.32E-14 % MPC 4.42E-5 The following data which was not available at time of report preparation should be added to Table 1-2 of the Semiannual Monitoring Report January 1,1979, through June 30, 1979.

2.0 RADIOACTIVE AIRBORNE RELEASES Radioactive airborne releases during normal plant operation are reported by total release in Table 2-1, and summarized by isotope in Table 2-2. The release paths contributing to radioactive airborne releases during this reporting period were the auxiliary building vent stack, Unit 1

ontainment purge stack, Unit 2 containment purge stack, drumming area vent stack, gas stripper building ventilation exhaust, combined air ejector decay duct exhaust and turbine building ventilation exhaust.

There were five gas decay tank releases during this report period. 2.1 Additions to the Semiannual Monitoring Report, January 1,

As a result, the semiannual report specified by item 16.6.2.a of the Technical Specification is not applicable. 9 7.0 NON-RADIOACTIVE CHEMICAL RELEASES 7.1 Scheduled Chemical Waste Releases Scheduled chemical waste 1 leases to the circulating water system for the period of 07-01-79 to 12-31-79 included 3,217,292 gallons of neutralized clear water waste. The waste water contained 638 pounds of suspended solids and 183,123 pounds of dissolved solids.* When averaged over the reporting period, these discharges represented 37.79% of the Technical Specification limit for dissolved solids and .277% of the Technical Specification limit for suspended solids.** The concentration increases of daemical waste in the circulating water system during the period of chemical releases ranged from 4.89 to 7.89 ppm dissolved solids and from 3.14E-04 to 8.45E-02 ppm suspended solids.** Plant chemical records indicated that the following amounts of chemicals were released in the form of neutralized waste: Sodium 48,211 pounds Sulfate 109,536 pounds

  • Chemical releases calculated are based upon neutralized tank analysis prior to discharge.
    • Based on calculations during times of actual discharges.

7.2 Miscellaneous Chemical Waste Releases Miscellaneous chemical waste releases to the circulating water system from the retention pond for the period of 07-01-79 to 12-31-79 included 11,600,000 gallons of clear water waste. The waste water contained 1,680 pounds of suspended solids and 84,200 pounds of dissolved solids.* When averaged over the reporting period, these discharges were 2.49% of the Technical Specification limit for dissolved solids and 0.089% of the limit for suspended solids. Retention pond analysis and plant chemical records indicate that the following daemicals were released in the form of clear water waste from the retention pond. Sodium 7,689 pounds Chloride 11,866 pounds Phosphate 130 pounds The balance of the dissolved solids were in the form of soluble calcium and magnesium compounds resulting from the plant makeup water cold lime softening process.

  • Chemical release calculations are based on retention pond analyses during the period 07-01-79 to 12-31-79.

8.0 CIRCULATING WATER SYSTEM OPERATIONS The circulating water system operation during this reporting period for periods of plant operation is described in Table 8-1. d 9.0 LEAK TESTING OF RADIOACTIVE SOURCES During the reporting period, all applicable scaled radioactive sources were leak tested according to Technical Specification requirement 15.4.12. Results of the leak testing showed no removable contamination greater than 0.005 micro-Curies from sealed radioactive sources. p TABLE 8-1 CIRCULATING WATER SYSTEM OPERATION July August Sentember October November Dece mbe r Average Volune Cooling UNIT 1 598.1 505.9 579.8 51.'. 2 270.9 327.9 Water Discharge, Million Gal / Day UNIT 2 474. 3 596.7 593.1 634.9 633.4 434.2 Average Cooling Water UNIT 1 55.6 57.2 55.3 53.1 41.6 37.9 Intake Temperature 4) Degrees F UNIT 2 55.4 58.1 54.9 52.3 43.3 39.0 Average Cooling Water UNIT 1 71.9 69.2 71.4 64.4 43.3 53.7 Discharge Temperature 4) Degrees F UNIT 2 67.9 74.0 70.6 67.7 58.1 61.5 Average Ambient UNIT 1 52.4 55.3 52.5 50.6 41.7 35.7 Temperature Degrees F UNIT 2 (3) ( 3) (3) ( 3) ( 3) ( 3) (1) Unit 1 was shut down for refueling from October 8, 1979, to November 22, 1979.
