1.0 RADIOACTIVE LIQUID RELEASES Radioactive liquid releases via the circulating water discharge are summar-ized for total release and by individual source on a monthly basis in Table 1-1.

An isotopic breakdown of the total radioac ive liquid release is presented in Table 1-2.

The total radioactive liquid release excluding tritium for this reporting period was 1.14E-01 Curies which included 7.28E-02 Curies of processed radioactive waste and primary coolant system letdown, 4.15E-02 Curies of Unit 1 steam generator blowdown and 3.00E-04 Curies of Unit 2 steam generator blowdown. The total tritium release for this reporting period was 379 Curies, which included 574 Curies of processed radioactive waste and primary coolant system letdown, 3.69 Curies of Unit 1 steam generator blowdown, 3.85E-02 Curies of Unit 2 steam generator blowdown, and 2.38E-01 Curies of retention pond effluent. All radioactive liquid releases to Lake Michigan were made through the circulating water discharge.

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 containment 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 two gas decay tank releases during this report period.

Thirty-six (36) new assemblies were also received for Unit 2.

No spent fuel assemblies were shipped from Unit 1 or Unit 2.

m 5.0 RADIOLOGICAL EINIRONMENTAL MONITORING Radiological environmental monitoring conducted by Point Beach Nuclear Plant for the period July 1, 1978, through December 31, 1978, consisted of air filters, gamma dose, vegetation, Lake water, well water, milk, shoreline silt, and soil samples collected and analyzed in accordance with Technical Specification 15.4.10.

Minor amounts of Cs-137 have been occasionally noted in milk samples as expected from the atmospheric nuclear weapons tests conducted by the Chinese within the last few years. The most recent Chinese detonation on December 14, 1978, did not produce any immediately noticeable fallout but can be expected to result in increased airborne activity accompanying the mixing of atmospheric layers this coming spring.

All other measurements obtained this period are well within the normal range, and no unusual results or significant departures from the normal were noted.

No.

    • Low chemical yield for one milk sample resulted in poorer sensitivity.

6.0 NON-RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM In accordance with Amendment Nos. 29 and 33 to Facility Operating License Nos. DPR-24 and DPR-27, dated November 4, 1977, the Environmental Technical Specifications for the Point Beach Nuclear Plant Unit Nos. 1 and 2 were modified to allow temporary suspension of the non-radiological environmental monitoring program. Licensees were required to analyze the results of the five years of monitoring and compare to preoperational and historical data to assess trends in environmental impact over the period of the study and submit a summary report to the NRC.

This sumary report was submitted on July 3, 1978, and is referenced in lieu of the semiannual report specified by 16.6.2.a.

7.0 NON-RADIOACTIVE CHEMICAL RELEASES 7.1 Scheduled Chemical Waste Releases Scheduled chemical waste releases to the circulating water system for the period of 07-01-78 to 12-31-78, included 2,841,948 gallons of neutralized clear water waste.

The waste water contained 481.4 pounds of suspended solids and 148,926 pounds of dissolved solids.*

When averaged over the reporting period, these discharges represented 37.62% of the Technical Specification limit for dissolved solids and 0.250% of the Technical Specification limit for suspended solids.**

The concentration increases of chemical waste during period of chemical releases ranged from 1.24 to 7.83 ppm dissolved solids and from 1.08E-03 to 7.48E-02 ppm suspended solids.**

Plant chemical records indicated that the following amounts of chemicals were released in the form of neutralized waste:

Sodium 44,379 pounds Sulfate 103,849 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 07-01-78 to 12-31-78 included 2,360,000 gallons of clear water waste.

The waste water centained 258 pounds of suspended solids and 15,491 pounds of dissolved solids.* When averaged over the reporting period, these discharges were insignificant with respect to Technical Specification limits.

Retention pond analysis and plant chemical records indicate that the following amounts of chemicals were released in the form of clear water waste from the retention pond.

Sodium 6,420 pounds Chloride 9,909 pounds Phosphate 25 pounds Chemical release calculations are based on retention pond analysis during the period 07-01-78 to 12-31-78.

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.

9.O LEAK TESTING OF RADIOACTIVE SOURCES During the reporting period, all applicable sealed 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 microcuries from sealed radioactive sources.
