1 A.

RADIOLOGICAL 1.

INTRODUCTION The data obtained by an analysis of samples taken during 1982 was statistically analyzed at the 95% confidence level by the method described in Consumers Power Company internal procedures RSD-E-03.

The data was statically evaluated against two criteria. The first-is the critical level which indicates the analysis of samples taken from near sites are higher than those taken from remote control sites but the difference is not significant. The second is the detection level (two times the critical level) which indicates the minimum detectable difference has been exceeded. Doses to the public will be calculated if the detection level is exceeded.

2.

LISCUSSION AND INTERPRETAT' ION OF RESULTS a.

Air Samples Statistical analysis of the airborne particulate sampling results between near site and control sites did not exceed the critical level.

Control sites were often higher than the near plant sites.

No I-131 activity was reported above the minimum detectable level.

Analysis was done on 622 of the 636 required samples. Two samples had no flow and were not analyzed acd 12 samples were deleted because of sampling malfunctions where sample flow was estimated.

These missing analysis do not indicate a substan-tial reduction in the air sample program. The Technical Specification sensitivities requirements were met and no action levels were execeded.

These results are consistent with expected results based on actual plant effluents and site meteorology.

b.

Lake Water Statistical analysis between the site lake inlet and the South Haven treated drinking water showed the critical level was not exceeded for Gross Beta or tritium analysis results.

In addition, the South Haven analysis was compared with the Charlevoix drinking water and showed no difference above the critical level. The lake water outlet sample had tritium levels above the detection limit. This is consistent with i

l reported site effluents as tritium releases were made every l

month during 1982. These measured releases account for the observed concentrations within 25%.

IC0383-0013A-RS01 i

g These observations are consistent with expected results based upon the site effluent data. Technical Specification sampling and sensitivity requirements were met and no action levels were exceeded.

4 c.

Drinking Water See lake water and well water discussion.

d.

Well Water Statistical analysis between the site well supply and two off site locations showed the critical level was not exceeded. Two analysis at the State Park well location met or exceeded action level requirements of 10 pCi/l gross beta and the required gamma analysis was run. No detectable gamma activity was found in either sample. Location SP has been historically higher than the other two well locations.

Technical Specification sampling and sensitivities were met.

Ei_lh Problems with the milk sampling program indicated a special report was required by Technical Specification 6.9.3.2.

This was submitted on 2-28-83. Eight (8) near site samples and nine (9) control site samples were missed in 1982 until the program was corrected. The problems with missing samples are detailed in the special report and will not be repeated except as they affect statistical analysis. The missing control samples were not considered crucial as the Big Rock Point control sample could reasonably be used for our statistical analyses. At least two near site samples were analyzed each month except August when procedure inadequacies caused by the transfer of the analytical lab from Chicago, Illinois to Albuquerque, New hexico, allowed the samples to spoil and analyses could not be run.

Statistical analyses between near sites and control sites (including the Big Rock Point control) showed the critical l

level was not exceeded for Sr-90 and Cs-137 analysis.

I-131 was less than detectable for all samples. Sensitivities were greater than our procedural requirements but did not exceed Technical Specification requirements.

Samples data for Sr-90 and Cs-137 is consistent with 1981 analysis. Notwithstanding the missing samples, the sampling program analysis gives reasonable assurance that effluents did not result in exposure to the public in excess of 5% of 10 CFR 20 limits.

IC0383-0013A-RS01 l

3 f.

Sediment Statistical analyses for gross beta between near sites and the control site off South Haven Municipal Beach showed the criti-cal level was not exceeded. No detectable Sr-90 was reported and only one of six near sites showed a Cs-137 reading above the minimum detectable limit. This is consistent with histot-ical data and published environmental reports showing levels of Sr-90 and Cs-137 in Lake Michigan remaining from weapons testing.

g.

Organic - Fish and Crops The action limit for organic samples in Technical Specification 4.11.2 (50 pci) is not appropriate for organic type samples, so the listed analysis requirements to Technical Specification Table 4.11.2 are followed.

Fish sampling was added to the program this year. Sr-90 analysis ranged from.02 to.17 pCi/g (wet). Only one of six samples show Cs-137 above minimum detectable level (0.11 pCi/g 4

wet). This is consistent with levels published in environ-mental reports (Argonne Ecology Reports and Environmental Technology).

h.

Gamma Dose - TLD Both onsite and near site TLD analyses were evaluated against l

the control sites.

No monthly, quarterly or the annual anal-yses exceeded the critical limit. On site annual TLDs had a critical level of 3.7 mR/ year and near site annual TLDs had a

, critical level of 5.2 mR/ year. This is consistent with expected results based on reported effluents and meteorology and indi-cates that effluents did not exceed 5% of 10 CFR 20 limits.

Five of 216 on or near site monthly TLDs were missing and one of the 36 control sites samples was missing. Six of 73 on or near site quarterly TLDs and four of 18 on or near site annual TLDs were also missing. These missing samples do not indicate a substantial reduction in the gamma dose analysis program.

Technical specification analysis sensitivities were met.
