SEMIArWAL MONITORING REPORT January 1, 1993 to June 30, 1993 1.0 RADIOACTIVE LIOUID RELEASES The total radioactive liquid release, excluding tritium for this reporting period, was 1.40E-01 curies. This included 5.75E-2 curies in processed radioactive waste and primary coolant system letdown, 1.91E-04 curies in Unit I steam generator blowdown, 8.22E-02 curies in Unit 2 steam generator blowdown and 1.9BE-04 curies in retention pond effluent.

The total tritium release for this reporting period was 2.09E+02 curies.

This included 2.05E+02 curies in processed radioactive waste and primary coolant system letdorn, 2.01E-02 curies in Unit 1 steam generator blowdown, 2.82E+00 curies in Unit 2 steam generator blowdown and 7.60E-01 curies in retention pond effluent.

5.0 RADIOLOGICAL ENVIRONMENTAL MONITORING 5.1 Introduction The results in this Semiannual Report are presented in the new i 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 l 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:

Sample: the type of the sample medium

Description:

the type of measurement LLD: the a criori lower limit of detection N: the number of samples analyzed Low: the lowest measured value i its associated 2a counting error Average: the average value i the standard deviation of N samples High: the highest measured value i its associatcd 20 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 LLD which is lower than that required by RETS is used. For these analysec, both LLDs are listed with the RETS 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 table. 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 January 1, 1993 through June 30, 1993 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. Site E-12, located on the discharge flume pier continues l to exhibit some of the lowest values.

l The analyses for individual radionuclides in environmental samples does not reveal any unexpected results. Sr-90 continues to persist in milk and water. Cs-137 continues to persist in milk, water, sediment, fish, algae, vegetation, 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.

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 I-131 in milk (1 of 18 samples), I-131, Co-60, Fe-59, and Zr-Nb-95 in water (each 1 of 30 samples). Although the concentration of Zr-Nb-95 in the composite from the discharge flume appears to be a real positive value at 7.1 1 3.6 pCi/1, this value is is not statistically different from typical blank values for this analysis. Blank values for Zr-Nb-95 are 2.4115.02-and 1.50 3.17 pCi/1. Other values also 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.
