SEMIANNUAL MONITORING REPORT July 1, 1992 to December 31, 1992 3.0 PADICACTIVE LIOUID RELEASES The total radioactive liquid release, excluding tritium for this reporting period, was 3.32E-01 curies. This included 2.33E-01 curies in processed

'dioactive waste and primary coolant system letdown, 2.42E-04 curies in v4.. t 1 steam generator blowdown, 1.00E-01 c - les in Unit 2 steam generator blowdown and 1.70E-04 curies in retention pond effluent.

The total tritium release for this reporting period was 2.17E+02 curies.

This included 2.17E+02 curies in processed radioactive waste and primary coolant system letdown, 7.37E-02 curies in Unit I steam generator blowdown, 5.51E-01 curies in Unit 2 steam generator blowdown and 9.33E-02 curies in retention pond effluent.

1.1 Circulatina Water Radionuclide Pelease Summary 3.1.1 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.

5.0 FADIOLOGICAL ElWIPONMENTAL MONITORING 5.1 Introduction The results in this Semiannual Report are presented in the new format which was initiated with the January - June 1992 Report.

Results are reported directly as measured, including negative and zero values. This eliminates the distortion of the results and long-term trends which occurs when the LLD is used to censor results that are below the LLD.

This reporting convention follows that recommended in Health Physics Society Committee Report HPSR-1 (1980) released as document EPA 520/1-80-012.

The REMP results are presented in Table 5.1.

This table contains the following information:

the highest measured value i its associated 2e counting error Units:

the units of measurement Additional information also is presented in Table 5.1.

Not all of the results in Table 5.1 are required by the PBNP radiological effluent technical specifications (RETS)

Non-RETS items and values are noted by an asterisk (*).

For certain analyses, an 9

LLD which is lower than that required by RETS is used.

For these analyses, both LLDs are listed with the RITS LLD given in parentheses. Occasionally, anomalous results are obtained which lie well outside of the range of expected values.

If, upon investigation, these values are found not to be the result of PBNP operations they will not be listed in the cable.

In this case, the highest reported value will be footnoted and the omitted value discussed in the narrative portion of this section.

Blank values have not been subtracted from the results presented in Table 5.1.

5.2 Discussion Radiological environmental monitoring conducted at the Point Beach Nuclear Plant from July 1, 1992 through December 31, 1992 consisted of air filters, milk, lake water, well water, soil, fish, shoreline sediments, algae, vegetation, and TLDs.

All TLD results for the reporting period were within the normal range.

Although the third quarter value for site E-32 was above the average of the other sites, it was within the normal range.

This site had the highest result for three of the four quarters of 1992.

Results f; n two nearby sites were comparable to the remaining sites.

Tne reason for the higher values at E-32 is unknown. Results will be tracked to see if a pattern develops.

The analyses for individual radionuclides in environmental samples does not reveal any unexpected results.

Sr-90 and Cs-137 continue to persist in milk, water, sediment, fish, algae, and soil.

These radionuclides routinely occur in environmental samples collected around the world. The occurrence of these radionuclides in the environment is attributable to the large scale atmospheric weapons tests of the 1960's, less frequent testing in the 70's and 80's, and to the Chernobyl accident.

Tritium concentrations continue to be low and are slightly lower than the first 6 months of 1992.

Two H-3 concentrations are not statistically different from zero.

Measured concentrations of other radionuclides occur as positive and negative values scattered around zero.

Although the positive values are usually smaller than their associated error, small, non-zero values (below the associated LLDs) occur for Ba-La-140 in milk (1 of 18 samples), I-131 in water (3 of 30 samples), and Co-60 and Mn-54 in water (each 1 of 30 samples). However, the values are comparable to the values obtained for " blanks" so that there would be no statistical difference from zero if blank values were subtracted. Therefore, these results appear to be attributable to statistical variations. Three of the four filamentous algae samples had small amounts of Co-60 and/or Cs-134, both of which were discharged from PENP during this reporting period. This result is not surprising because these algae are known to have high bioaccumulation factors for Cs and Co: Cs-137, +1000; Co-60, 250-2800 (NCRP 76).

One of the Co-60 results may be due to statistical fluctuations. However, two October recults probably are real because they are associated with Cs-137 concentrations (0.100 and 0.071 Pci/g) about 2 times greater than the August samples.

Furthermore, in the sample with the highest Cs-137, the Cs.'34 value, 0.54 pCi/g, is six standard deviations greater than zero.

The highest October result for algae occurs at a site 1.6 miles N of PBNP where the predominant current direction is from N to S.

Pursuant to Technical Specification 15.7.7.D, a visual verification of animals grazing in the vicinity of the Point 10

Beach Nuclear Plant site boundary was completed on July 28, 1992, to ensure that milk sampling locations remain as conservative as practicable. No significant change in the use of pasture lands was noted. The existing milk sampling program conducted at PBNP continues to be acceptable.

The wastewater contained 6.47E+02 pounds of suspended solids and 4.14E+05 pounds of dissolved solids.

Scheduled chemical waste releases are based on the average analytical results obtained f rom sampling a representative number of neutralizing tanks.

8.0 LEAK TESTING OF RADICAC"TIVE SOURCES During this reporting period, all applicable sealed radioactive sources were leak tested in accordance with Technical Specification 15.4.12.

Leak test results were all <0.005 pCi.

9.0 MISCEL W EOUS REPORTING REOUIREMENTS 9.1 Pevisions to the PBNP Office Dose Calculation Manual (ODCM) and Process Control Procram (PCP)

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

The Environmental Manual, Revision 9, was issued in November.

The revision consisted of the addition of five new TLD sites and minor administrative changes such as the incorporation of the new PBNP form numbering system.
