9,0 RADIOL,0GICAL ENVIRONMENTAL MONITORING PROGRAM (REMP) 9.1 Introduction l The REMP results in this Annual Report are presented in the new format which was initiated with the January - June 1992 Semiannual Monitoring Report. Results are reported directly as l 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. l This reporting convention follows that recommended in Health Physics Society Committee Report HPSR-1 (1980) released as document EPA 520/1-80-012. '
9.2 Objective l
The objective of the PBNP REMP is to fulfill the requirements of 10 CFR 20.1302, PBNP General Design Criterion (GDC) 17, GDC 64 of Appendix A to 10 CFR 50, and Sections IV.B.2 l
and IV.B.3 of Appendix I to 10 CFR 50. Therefore, the REMP collects samples from various l cmironmental media in order to provide data on measurable levels of radiation and radioactive materials in the principal pathways of emironmental exposure.
l For the water exposure pathway, the samples include water as well as the biological integrators, fish and filamentous algae. Because of their migratory behavior, fish are wide area integrators.
l In contrast, the filamentous algae periphyton are attached to shoreline rocks and concentrate nuclides from the water flowing by their point of attachment.
The air-grass-cow-milk exposure pathway is important because of the many dairy farms around PBNP. Therefore, the REMP includes samples of air, general grasses, and milk in the PBNP emirons.
For the measurement of the levels of ambient emironmental radiation that may be affected by direct radiation from PBNP, the REMP employs a series of TLDs which are situated around PBNP.
9.3 Sampling Parameters l Samples are collected at the fregoency indicated in Table 9-1 from the locations described in Table 9-2 and shown in Figures 9-1 and 9-2 9.4 Analytical Parameters
, The types of analyses and their frequencies are given in Table 9-3. The LLDs for the various analyses are found in Table 9-4 with the summary of the REMP results.
15 l
9.5 Summary of REMP Results A summary of the REMP results are presented in Table 9-4. The table contains the following information:
Sample: the type of sample medium
Description:
the type of measurement LLD: the a onorilower limit of detection N: the number of samples analyzed Low: the lowest measured value
- its associated 2s counting error Average: the average value
- the standard deviation of N samples High: the highest measured value
- its associated 2s counting error Units: the units of measurement Additional information also is presented in Table 9-4. Not all of the results in Table 9-4 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 analyses, 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. These results will be investigated and discussed in the narrative portion of this section. Blank values have not been subtracted from the results presented in Table 9-4.

9.6 Discussion Radiological environmental monitoring conducted at the Point Beach Nuclear Plant from January 1,1995 through December 31,1995 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 to exhibit some of the lowest values whereas E-32, approximately 1 mile west of the plant, continues to exhibit some of the highest. The higher values at E-32 have been noted since TLDs were first located at this site. The reason for this result is not known and continues to be tracked. However, during 1995 the TLD results at E-32 have been lower than in the previous years. Therefore, the differences between TLD results from E-32 and from sites E-3 and E-31, located about 1200 feet north of E-32 at about the same distance from the plant, which typically have been 0.1 - 0.4 mR/ week, were only 0.1 - 0.2 mR/ week in 1995.
The analyses for individual radionuclides reveals that Sr 90 and Cs-137 continue to ocur in emironmental samples. Sr-90 continues to persist in milk and lakewater. Cs-137 occurs in shoreline sediment deposits, fish, algae, vegetation, and soil. These radionuclides routinely occur in emironmental samples collected around the world and are attributable to the large scale atmospheric weapons tests of the 1960's and the less frequent testing in the 70's and 80's, and as a well as to the Chernobyl accident. The lughest Cs-137 concentrations in soil occurs at E-06, the Point Beach State Forest. This occurs because campfire ashes, from trees which incorporated fallout Cs-137 in the 1960s, is being scattered around various camp sites in the area. The occurrence of Cs-137 in tree ash has been obseived in other areas of the United States.
Lake water tritium concentrations continue to be low. These samples are composited monthly for quarterly analysis. Most of the results are in the 100 - 250 pCi/l range. Three of the H-3 results i are in the 950 - 5500 pCi/l range. Two of these results were obtained approximately 1.7 and 4 l miles north of PBNP with the highest concentration the furthest north. The predominant current along this side of Lake Michigan is from north to south which indicates that PBNP is not the i likely source of these elevated H-3 concentrations. One composite result of 1348 pCi/l from the l discharge canal, E-12, included a monthly sample taken at the same time as a holdup tank was l 4 '
being discharged in November. Analyses of the monthly samples showed that the October and December H-3 concentrations were less than 175 pCi/l whereas the November concentration
' from the discharge canal was 3900 pCi/1. Over the past two years, tritium blanks have yielded results in the range of-74.6
- 80.5 to 148
- 101 pCi/1. Only the H-3 results from E-01 for the first quarter of 1995 and from E-12 for the 4th quarter appear to be attributable to PBNP discharges. Tritium, in addition to being produced by water-cooled reactors such as PBNP, also is a naturally occurring radionuclide.
All of the isotopic well water results are small positive and negative values indistinguishable from zero. Only the gross beta results, which are attributable to naturally occurring radionuclides, are significantly positive.
For the remaining suite of RETS specified radionuclides, measured concentrations 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) whose
- 2s error does not overlap zero occur for Co 58 and Co-60 in algae. These cobalt concentrations are low, two to four times lower than the Cs-137 concentrations which are the result of fallout which circulates through the Lake Michigan ecosystem. The October Co-60 concentration is 22 l l
l
T s
about two times the 2a counting error at E-05 (0.02310.012), about 1.7 miles north of PBNP.
This also occurs for Co 58 at the same site in both the August and October samples (0.017 i 0.011 and 0.043 i 0.021) and at E-12, near the PBNP discharge (0.029 i 0.012), in August.
Both of these radionuclides were discharged by PBNP during 1995: Co-60 every month during 1995 and Co-58 from March - December. However, as previously discussed with regard to H 3, most of the positive results are obtained north of PBNP and not near the discharge as expected if PBNP were the primary source of these cobalt isotopes. Although no measurable Co-58 or Co-60 were found in the water samples from E-05 during the year, it is known that filamentous algae have cobalt bioaccumulation factors on the order of 250 to 2800. Therefore, it is not surprising that the cobalt isotopes were found in the algae and not in the water. Freshwater fish have a bioaccumulation factor for Co-60 comparable to that of algae, about 1000. However, neither Co-58 nor Co-60 were observed in fish analyzed during the year. Therefore, it is possible that the algae results are false positives. Finally, it should be noted that the Co-58/60 levels found in the ,
algae are at least ten times lower than the applicable LLDs and about 1000 times lower that the '
NRC notification levels.
l 9.7 Land Use Census l
In accordance with the requirements of Technical Specification 15.7.7.D, a sisual verification of animals grazing in the vicinity of the Point Beach Nuclear Plant site boundary was completed in July of 1995 to ensure that the milk sampling locations remain as conservative as practicable. No significant change in the use of pasture lands was noted. Therefore, the existing milk sampling program continues to be acceptable.
9.8 Conclusion Based on the results of the PBNP REMP for 1995, PBNP effluents had a minimal affect on the PBNP emirons. Only the elevated H-3 concentrations in the one water sample from the effluent I channel, E-12, and one lakewater sample from E-01, the meteorological tower, are attributable to I I' PBNP cfliuent. All other positive results are from other sources and from the persistence and recycling of fallout in the emironment.
