i 1.0 RADI0 ACTIVE LIQUID RELEASES J
The total radioactive liquid release excluding tritium for this reporting i period was 7.01E-01 Curies. This included 3.77E-02 Curies in processed
- . radioactive waste and primary coolant system letdown, 1.58E-01 Curies in Unit 1 steam generator blowdown, 5.05E-01 Curies in Unit 2 steam generator
, blowdown, 2.0E-04 Curies in the retention pond effluent and 2.S9E-05 Curies in sewage sludge.
l The total tritium release for this reporting period was 3.89E+02 Curies.
This included 3.86E+02 Curies in processed radioactive waste and primary coolant system letdown, 5.70E-02 Curies in Unit 1 steam generator blowdown, 2.77E+00 Curies in Unit 2 steam generator blowdown, and 2.80E-02 Curies in the retention pond effluent.
l All radioactive liquid releases to Lake Michigan were made through the I circulating water discharge system.
l 1.1 Circulating Water Radionuclide Release Summary 1.1.1 Releases During Current Reporting Period 1 Radioactive liquid releases via the circulating water discharge i are summarized by individual source, total, and equivalent Curie i release on a monthly basis and presented in Table 1-1.

4.0 NEW & SPENT FUEL SHIPMENTS AND RECEIPTS During this reporting period, a total of 28 new fuel assemblies were received from Westinghouse Electric Corporation for Unit 1. The new fuel assemblies received for Unit 1 were used for the Spring, 1986 refueling.
There were no spent fuel shipments made from Point Beach Nuclear Plant during this reporting period.

5.0 RADIOLOGICAL ENVIRONMENTAL MONITORING Radiological environmental monitoring conducted at Point Beach Nuclear Plant from July 1, 1985 through December 31, 1985 consisted of air filters, milk, lake water, well water, soil, fish, shoreline sediments, algae, vegetation, and TLDs.
No significant deviations from normal results, attributable to the operation of the Point Beach Nuclear Plant, were identified during this six month reporting period. However, elevated radioactivity levels were observed in environmental samples collected in May and June following the April 26 Chernobyl Nuclear Plant accident. Elevated I-131 and Cs-137 levels were detected in two milk samples collected on June 4, 1986. Above normal levels of I-131, Cs-137, and Ru-103 were detected in air samples collected on May 12, 19, 27 and on June 2. These elevated levels were determined to be attributable to the Chernobyl accident.

9.0 MISCELLANEOUS REPORTING REQUIREMENTS 9.1 Revisions to the PBNP Offsite Dose Calculation Manual (ODCM) and Process Control Progra (PCP)
No revisions were made to either the ODCM or PCP during this reporting period.
9.2 Interlaboratory Comparison Program The analytical laboratory contracted to perform the radioanalyses of the environmental samples participated in the EPA Interlaboratory Comparison Program during this reporting period.
9.3 Deviations from Specified Environmental Sample Types, locations, and Frequencies There were no deviations from the sampling types, frequencies, and locations specified in Technical Specification 15.7.7 during this reporting period.
9.4 Summary of Unachievable Specified Environmental LLDs LLDs listed in Table 15.7.7-2 of the PBNP Technical Specifications were not accomplished for all samples during this reporting period.
Those a priori LLDs which were not accomplished included the follow-ing:
- 1. The LLD for Fe-59 in one fish sample was not achieved due to a small sample size.
- 2. The LLD for Ba-La-140 in two lake water samples was not achieved due to a delay in saicple analysis.
- 3. Tne LLD for I-131 was not achieved in six airborne and seven vegetation samples due to a delay in sample analysis.
The delay in analyses of water, vegetation, and air samples which resulted in the inability to achieve the a priori LLDs occurred due to a backlog of samples at the contracted analytical laboratory following the April 26, 1986 Chernobyl Nuclear Plant accident.
l Following the Chernobyl accident, a significant increase in the number of samples received and analyzed by the analytical laboratory resulted in less timely analyses which precluded achieving the specified a priori LLDs.
9.5 Special Circumstances No special circumstances report regarding operation of the explosive gas monitor for the waste gas holdup system were needed during this reporting period.
