1.0 RADIOACTIVE LIQUID RELEASES Radioactive liquid relear.es via the circulating water discharge are summarized for total release and by individual source on a monthly basis in Table 1-1.
7a 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 7.18E-01 Curies which included 4.86E-02 Curies of processed radioactive waste and primary coolant system letdown,
- 6. 37E-01 Curies of Unit 1 steam generator blowdown, 3.23E-02 Curies of Unit 2 steam generator blowdown.
There was no measurable release other than tritium via retention pond effluent. The total tritium release for this reporting period was 479 Curies, which included 473 Curies of processed radioactive waste and primary coolant system let-down, 5.03 Curias of Unit 1 steam generator blowdown,.783 Curies of Unit 2 steam generator blowdown, and.431 Curies of retention pond effluent. All radioactive liquid releases to Lake Michigan were made through the circulating water discharge.

l 5.0 RADIOLOGICAL ENVIRONMENTAL MONntRING Radiological environmental monitoring conducted by Point Beach Nuclear Plant for the period from July 1,1980, through December 31, 1980,.
consisted of air filters, gamma dose, vegetation, lake water, well l
water, milk, shoreline silt, soil, algae, and fish samples collected and analyzed in accordance with Technical Specification 15.4.10.
i l
All measurements obtained during this period are well within the i
i normal range except one milk sample in November which indicated a minor amount of I-131 (1.3 pCi/1). This is attributed to fallout from a Chinese nuclear detonation on October 16, 1980.
In addition, l
one shoreline silt sample in October yielded a slightly elevated gross beta concentration (19 pCi/g).
Investigation indicated no connection between this result and operation of Point Beach Nuclear plant.

6.0 NON-RADIOLOGICAL ENVIRO?24 ENTAL MONITORING PROGRAM In accordance with Amendment numbers 29 and 33 to Facility Operating
[
Licenses DPR-24 and DPR-27 respectively,, dated November 4, 1977, the
[
Environmental Technical Specifications for the point Beach' Nuclear
[
plant Units 1 and 2 were modified to allow temporary suspension of i
the non-radiological environmental monitoring program pending NRC re-view of the summary report of the five years of monitoring. As a result, the semiannual report specified by Item 16.6.2.a of the Tech-
[
nical Specification is not applicable.

7.0 NON-RADICACTIVil CHEMICAL RELEASES 7.1 Scheduled Chemical Waste Releases Scheduled chemical waste releases to the circulating water system for the period of 07-01-80 to 12-31-80 included 3,983,675 gallons of neutralized clear water waste.
The waste water contained 416 pounds of suspended solids and 210,353 pounds of dissolved solids.*
When averaged over the reporting period, these discharges represented 39.14% of the Technical Specification limit for l
dissolved solids ar;d.15% of the Technical Specification limit for suspended solids.**
The concentration increases of chemical waste in the circulating water system deing the period of chemical releases ranged from 0.62 to 8.23 ppu dissolved solids and from 3.0E-04 to 2.6E-02 ppm suspended solids.**
Plant chemical records indicated that the following amounts of chemicals were released in the form of neutralized waste:
Sodium 50,589 pounds Sulfate 130,604 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 th retention pond for the period of 07-01-80 to 12-31-80 included 13,500,000 gallons of clear water waste. The waste water contained 1,200 pounds of auspended solids and 52,200 pounds of dissolved solids.* When averaged over the reporting period, these discharges were 0.68% of the Technical Specification limit for dissolved solids and 0.028% of the limit for suspended solids.
Retention pond analysis and plant chemical records indicate that the following chemicals were released in the form of clear water waste from the retention pond.
Sodium 6,662 pounds Chloride 10,281 pounds Phosphate 16.6 pounds The balance of the dissolved sclids were in the form of soluble calcium and magnesium compounds resulting from the plant makeup water cold lime sof tening process.
- Chemical release calculations are based on retention pond analyses during the period 07-01-80 to 12-31-80.,

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.
9.0 LEAK TESTING OF RADIOACTIVE SOURCES During the reporting period, all applicable sealed radioactive sources were leak tested according to Technical Specification require-ment 15.4.12.
Results of the leak testing showed no removable con-tamination greater than 0.005 microcuries from sealed radioactive so urces.
