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 re-porting period was 0.456 Curies which included 0.044 Curies of processed radioactive waste and primary coolant system letdown, 0.198 Curies of Unit I steam generator blowdown, and 0.214 Curies of Unit 2 steam generator blowdown. There was no detectable activity in retention pond effluent (other than tritium). The total tritium release for this reporting period was 297.7 Curies, which included 292.25 Curies of processed radioactive waste and primary coolant system letdown, 1.96 Curies of Unit I steam generator blowdown, 2.63 Curies of Unit 2 steam generator blowdown, and 0.862 Curies of retent_on 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.

4 The release paths contributing to radioactive airborne releases during this reporting period were the auxiliary building vent stack, Unit I containment purge stack, Unit 2 containment purge stack, drumming area vent stack, gas stripper building ventilation exhaust, combined air ejector decay exhaust and turbine building ventilation exhaust.

There were five gas decay tank releases during this report period.

5.0 RADIOLOGICAL ENVIRONMENTAL MONITORING Radiological environmental monitoring conducted by Point Beach Nuclear Plant from July 1, 1982, through December 31, 1982, consisted of air filters, gamma dose, vegetation, lake water, well water, milk, shoreline silt, soil, algae, and fish samples collected and analyzed in accord-ance with Technical Specification 15.4.10.

All measurements obtained during this period are within normal ranges, and no unusual results or significant departures from normal were noted.

6.0 NON-RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM In accordance with Amendment Nos. 29 and 33 to Facility Operating Licenses DIPR-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 the non-radiological envi-ronmental monitoring program pending NRC review of the summary report of the five years of monitoring. As a result, the semiannual report speci-fied by Item 16.6.2.a of the Technical Specification is not applicable.

l 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 July 1, 1982, to December 31, 1982, included 4,041,458 gallons of neutralized clear water waste. The waste water contained 456 pounds of suspended solids and 241,185 pounds of dissolved solids.* When averaged over the reporting period, these discharges represented 41.24% of the Technical Specification limit for dissolved solids and 0.18% of the Technical Specification limit for suspended solids.**

The concentration increases of chemical waste in the circulating water system during the period of chemical releases ranged from 0.386 to 9.301 ppm dissolved solids and from 0.000 to 0.062 ppm suspended solids.**

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

Sodium 72,310 pounds Sulfate 155,656 pounds

Chemical releases calculated are based upon neutralized tank analysis prior to discharge.

- Based on calculations during times of actual discharges for each individual neutralizing tank.

7.2 Miscellaneous chemical Waste Releases Miscellaneous chemical waste releases to the circulating water system from the retention pond for the period of July 1, 1982 to December 31, 1982 included 14,426,000 gallons of clear water waste. The waste water contained 1,468 pounds of suspended solids and 142,531 pounds of dissolved solids.* When averaged over the l

reporting period, these discharges were 1.45% of the Technical Specification limit for dissolved solids and 0.033% of the Technical Specification 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 8,624 pounds Chloride 13,308 pounds Phosphate 168 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.

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 requirement 15.4.12.

Results of the leak testing showed no removable contamination equal to or greater than 0.005 microcuries from sealed radioactive sources.
