1.0 ' RADIOACTIVE LIQUID RELEASES j*

Radioactive liquid releases via the circulating water discharge are-summiarized 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 1.2685 curies which included 1.0316 curies of processed radioactive waste.and primary coolant system letdown, 0.0329 curies of Unit I steam generator blowdown and 0.2028 curies _of Unit 2 steam generator j

blowdown. There was 0.0012 curies of detectable activity'in retention pond effluent (other than tritium). The total tritium release for this reporting l

period was.398.92 curies, which included 397.500 curies of processed radioactive _ waste.and primary coolant system letdown, 0.074 curies of Unit 1 steam generator blowdown, 1.262 curies of Unit 2 steam generator blowdown, and 0.081 curies of retention pond. effluent.. All radioactive liquid l

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 stick, Unit 1 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 three gas decay tank releases during this report period.

9.0 ERRATUM FOR 1984 SEMIANNUAL MONITORING REPORTS A confirmatory measurements program conducted on the Point Beach Nuclear Plant gamma spectroscopy system identified incorrect radioiodine charcoal cartridge calfbration factors for one of the four GeLi detectors. The calibration factors used to quantify radio-iodines in gaseous effluents were found to be non-conservative by a factor of approximately three (3). The gaseous effluent radiciodine values determined on the one detector have been corrected and the appropriate revisions have been made to the gaseous effluent release data. Revised Tables-2-1 for gross activity and corrected radio-iodine values for Tables 2-2 for both 1984 Semiannual Monitoring Reports are presented herein. The appropriate changes should be made to the corresponding tables in the 1984 reports.
