( The total radioactive liquid release excluding tritium for this -

/ reporting period was 4.61E-02 curies. This included 3.04E-02 curies in processed radioactive waste and primary coolant system letdown, 6.23E-03 curies in Unit I steam generator blowdown, 9.54E-03 curies in Unit 2 steam generator blowdown and <MDA curies in the retention pond.

The total tritium release for this reporting period was 2.05E+02 curies. This included 2.04E+02 curies in processed radioactive waste and primary coolant system letdown, 1.50E-01 curies in Unit 1 steam generator blowdown, 7.60E-01 curies in Unit 2 steam generator blowdown, and 8.05E-02 curies in the retention pond.

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

The new fuel assemblies received for Unit 2 were used for the fall 1988 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, 1988 through December 31, 1988 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.

6.0 NON-RADIOACTIVE CHEMICAL RELEASES 6.1 Scheduled Chemical Waste Releases

• Scheduled chemical waste releases to the circulating water system from July 1, 1988, to December 31, 1988, included 2.81E+06 gallons of neutralized wastewater. The wastewater contained 4.67E+02 pounds of suspended solids and 3.16E+05 pounds of dissolved solids. j l

l

• Scheduled chenical waste releases are based on the average analytical results obtained from sampling a representative number of neutralizing tanks. '

9.0 MISCELLANEOUS REPORTING REQUIREMENTS 9.1 Revisions to the PBNP Offsite Dose Calculation Manual (ODCM) and Process Control Program (PCP)

}

No revisions were made to the PCP or ODCM during this reporting l period.

9.2 Interlaboratory Comparison Program The analytical laboratory contracted to perform the radioanalyses of the PBNP environmental samples participated in the EPA l Interlaboratory Comparison Program during this reporting period.

9.3 Deviations from Jpecified Environmental Sample Types, Locations, and Frequencies No fish were available during the normal August collection period.

Therefore this sample was collected in November.

An airborne iodine sampling cartridge was missing from one monitoring site for the week ending November 14, 1988. Vandalism I is suspected.

l I

Two TLDs for the fourth quarter of 1988 were lost in the field.

Vandalism is suspected for one. The other was attached to a telephone pole that was replaced.

9.4 Summary of Unachievable Specified Environmental LLDs All LLDs listed in Table 15.7.7-2 of the PBNP Technical Specifications were achieved during this sampling period.

9.5 Special Circumstances No special circumstances report regarding operation of the explosive gas monitor for the waste gas holdup system was needed during this reporting period.
