ATTACHMENT Consumers Power Company Palisades Plant Docket 50-155 1984 RADIOLOGICAL ENVIRONMENTAL MONITORING REPORT Covering the Period from January 1 through December 31, 1984 April 16, 1985 30 pages IC0385-0099A-NL04
1 A. INTRODUCTION The data obtained by an analysis of samples taken during 1984 was statis-tically analyzed at the 95% confidence level by the method described in Consumers Power Company internal procedures RSD-E-03. The data was statistically evaluated against two criteria. The first is the statistical 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 report level (two times the statistical level) which is the minimum detectable difference that
~xceeds zero at a 95% confidence level. Doses to the public will be evaluated if the report level is exceeded. A total of 32 analytical results (15-Sr89, 15-Sr90, and 2-gross beta) were unavailable from the laboratory contractor in the following sample categories: 1) aquatic -
fish, 2) food crops, and 3) bottom sediments at time of report prepara-tion. A supplemental report will be issued when the sample results are received. Palisades was off-line for most of 1984 due to an extensive refueling outage. Power generation was resumed on November 22, 1984.
B. DISCUSSION AND INTERPRETATION OF RESULTS
- 1. Air Samples Statistical analysis of the airborne particulate sample data between perimeter and control sites did not exceed reporting level. In many instances; control sites sample values were higher than the peri-meter site values.
No I-131 activity was reported above minimum detectable levels.
A total of 627 samples were collected and analyzed; however 18 sample results were deleted from statistical evaluation due to low and/or estimated sample volumes. The missing sample results do not indicate any significant reduction in the overall sample program.
Technical Specification sensitivities were met. July air sample results exceeded the statistical levels but not any reportable limits.
The results are consistent with actual effluent releases and site-specific meteorology.
- 2. Lake Water Statistical analysis between the plant lake water intake and the South Haven treated drinking water samples showed that statistical levels for gross beta or tritium were not exceeded. The plant lake water outlet samples contained tritium above the statistical limit; however, this is consistent with monthly reported tritium effluent releases. There were no gross beta releases above the administra-tive notification limit of 10 pCi/l from lake-out discharge.
Technical Specification sampling and sensitivity requirements were met.

- 3. Drinking Water See lake water and well water discussion.
- 4. Well Water Statistical sample data analysis between the site well supply and two off-site locations showed that the statistical level was not exceeded. The State Park off-site control location has been historically higher in gross beta concentrations than either the township park off-site well or on-site well locations. To establish the cause of the higher State Park well water gross beta concentrations, a comparative K-40 analytical study between the State Park off-site well and the Palisades site well was initiated October 1984. Well water samples taken since June 1984-on have been analyzed. Results are inconclusive at this time. All Technical Specification sampling and sensitivity requirements were met.
- 5. Milk No problems were encountered in obtaining milk samples for 1984.
I-131 and Cs-137 were less than detectable for all sample locations.
Statistical analysis between site and control locations initially indicated that Sr-90 levels exceeded the reporting level. The difference between the means of the near site locations and the control locations was 1.29 pCi/l. The validity of this value is questionable because of an abnormally low control value. Values for 1984 for both Big Rock Point and Palisades were lower than 1983 values, as expected, from fallout decay. In addition there were no values for Sr-89 or Cs-137 above LLD values in the 1984 analysis results. The control value for Big Rock in 1984 was 2.3 pCi/l while Palisades was 1.5 pCi/l. In the years 1983 through 1984, Palisades had a control value over 1 pCi/l higher than Big Rock Point. For the above reasons and the fact that Palisades had been off-line during late 1983 and most of 1984, the positive indication is invalid. Copies of the milk analysis are attached. This trend will be closely monitored in 1985.
- 6. Sediment Statistical analyses of sediment data was done using control samples from the Ludington Pump Storage Facility (located approximately 200 miles North of South Haven) and site samples. Gross beta results did not exceed a statistical significance level. In many cases the control sample beta values were higher than the site values. The results of 10 analyses (5-Sr89 and 5-Sr90) were unavailable to complete a full data report for sediment samples; however initial results on 7 completed analyses from 12 samples indicate that Sr89 levels are MDL with Sr90 quantities being slightly above LLD limits.
No reportable Sr89 or Sr90 levels have yet been reached. Levels of Sr90 from 1984 and 1983 samples appear to be within 4% of each IC0385-0099A-NL04
1-1 3
other. No detectable levels of Csl37 were found at any sample location. Technical Specification sampling and analysis require-ments were met.
- 7. Organic - Fish .and Crops A total of 22 analyses results (10-Sr89, 10-Sr90 and 2-gross beta) were unavailable to complete a full data report for organic samples; however, initial results on 16 completed analyses from 26 samples indicated that reportable limits of Sr90 (from Technical Specifica-tion 4.11.2) were not exceeded. Sr90 results ranged from <.005 pCi/gm to 0.009 pCi/gm with no detectable levels of Csl37 found.
Technical Specification sampling and analysis requirements were met.
- 8. Gamma Dose - TLD There were 5 reported missing TLD's during 1984 with an additional 4 TLD reader cards being damaged (unreadable) at the laboratory.
Statistical analysis of TLD data was done by comparing all indicator locations to control locations. No monthly, quarterly or annual analyses exceeded the statistical level. The Palisades gamma dose sampling program consists of 23 TLD stations: 10 directly on-site; 10 off-site (1-6 mi); and *3 control locations. In separate compari-son of off-site TLD data and on-site TLD data to the control TLD locations, the on-site locations had an average of 5.1 mR/month to an average of 5.3 mR/month for control TLD's. The off-site TLD's average 5.5 mR/month. This is consistent with expected results based on reported ef(luent releases. Technical Specification analytical sensitivities were met.
C.
SUMMARY
No required Technical Specification analysis was missed in 1984.
Eighteen of the 627 air samples collected in 1984 were deleted from the statistical analysis because of estimated flows due to meter malfunctions.
- 1. Technical Specification requirements for calibration of air sampler meters was met.
- 2. A supplemental 1984 Palisades Annual Report will be forthcoming as soon as the 32 analytical results from 16 samples become available.
- 3. The missing or deleted results did not constitute a significant reduction in the overall program and no special reports per Techni-cal Specification 6.9.3.2 were made on 1984 requirements.
D. The 1984 data analysis was done by Teledyne Isotopes Midwest Laboratory, Northbrook, Illinois.
