1.0 RADIOACTIVE LIQUID RELEASES The total radioactive liytid release excluding tritium for this reporting

! period was 1.01E-02 curies. This included 3.50E-04 curies in processed

{ radioactive waste and primary coolant system letdown, 2.67E-03 curies in Unit 1 steam generator blowdown, 7.06E-03 curies in Unit 2 steam generator blowdown and <MDA curies in the retention pond.

The total tritium release for this reporting period was 1.64E+02 curies.

This included 1.82E+02 curies in processed radioactive waste and primary coolant system letdown, 3.51E-02 curies in Unit I steam generator blowdown, l 1.61E+00 curies in Unit 2 steam generator blowdown, and 4.51E-01 curies in the retention pond.

All radioactive liquid releases to Lake Michigan were made through the circulating water discharge system.

1.1 Circulating Water Radionuclides Release Summary l

1.1.1 Releases During Current Reporting Period Radioactive liquid releases via the circulating water discharge are summarized by individual source, total, and equivalent curie release on a monthly basis and presented in Table 1-1.

1.1.2 Additions to Previous Semiannual Monitoring Report The follo.iing information was not available at the time of the previous report preparation and should be added to Table 1-1 of the Semiannual Monitorir.g Report for July 1, 1988, through December 31, 1988.

6.0 NON-RADI0 ACTIVE CHEMICAL RELEASES 6.1 Scheduled Chemical Waste Releases

• Scheduled chemical waste releases to the circulating water system from January 1, 1989, to June 30, 1989, included 4.68E+06 gallons of I neutralized wastewater. The wastewater contained 3.98E+02 pounds of suspended solids and 3.66E+05 pounds of dissolved solids.

• Scheduled chemical waste releases are based on the average analytical '

results obtained from sampling a representative number of neutralizing tanks.

6.2 Miscellaneous Chemical Waste Releases

• Miscellaneous chemical waste releases from the retention pond (based lg

'g on effluent analyses) to the circulating water for Janaury 1, 1989, to June 30, 1989, included 3.33E+07 gallons of clear wastewater.

The wastewater contained 2.19E+03 pounds of suspended solids.

• Miscellaneous chemical waste released directly to the circulating water, based on amount of chemicals received, for January 1, 1969, to June 30, 1989, included 4.80E+04 pounds of sodium bisulfite and I 1.70E+04 pounds of sodium hypochlorite.

7.0 CIRCULATING WATER SYSTEM OPERATION The circulating water system operation during this reporting period for periods of plant operation is described in Table 7-1.

8.0 LEhK TESTING OF RADIOACTIVE SOURCES During this reporting period all applicable sealed radioactive sources were I leak tested in accordance with Technical Specification 15.4.12. Leak test results were all <0.005 pCi.
