1.0 INTRODUCTION

The following constitutes the current Monthly Progress Report for the Radio-logical Environmental Monitoring Program conducted at the Palisades Nuclear Generating Plant, Covert, Michigan. Results of completed analyses are pre-sented in the attached tables. Missing entries indicate analyses that are not completed and the results will appear in subsequent reports.

Data obtained in the program are well within the ranges previously encountered in the program and to be expected in the envtronmental media sampled.

None of the media sampled this month contained radioactivity attributable to the operation of Palisades N~clear Generating Plant.

For all gamma isotopic analyses, spectrum is computer scanned from 80 to 2048 Kev. Specifically included are Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, I-131, Ba-La-140, Cs-134, and Cs-137. Naturally occurring gamma-emitters, such as K-40 and Ra daughters, are frequently detected but not listed here. Data listed as 11 <11 are at the 4.66 sigma level, others are 2 sigma. Unless noted otherwise, the less than value ( 11 <11 ) reported under "Other Gammas" is for Co-60 and may be higher or lower for other radio-nuclides.

All concentrations except gross beta are decay corrected to the time of collection.

Deviations from Scheduled Sampling and Corrective Actions Taken All samples were collected within the scheduled period unless noted otherwise in the Listing of Missed Samples.

c Low gross beta value probably due to loose filter housing. Filter paper was light. and torn. Gross beta value will be excluded from the mean.

ENCLOSURE D APPENDIX A TELEDYNE INTERLABORATORY COMPARISON PROGRAM RESULTS OC0589-0127-NL04

Appendix A Interlaboratory Comparison Program Results

• Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These prograr.is are operated by agencies which supply environmental-type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. rhe purpose of such a program is to provide an independent check on the laboratory 1 s analytical procedures and to alert it to any possible problems.

Participant laboratories measure the concentrations of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits.

Results consistently higher or lower than the known values or outside the control lir.iits indicate a need to check the instruments or procedures used.

The results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water, air filters, and food samples during the period May 1984 through November, 1988. This program has been conducted by the U.S. Envirrinmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada.

The results in Table A-2 were obtained for thermoluminescent dosimeters (TLD s)1 during the period 1976, 1977, 1979, 1980, 1984, and 1985-1986 through partici-pation in the Second, Third, Fourth, Fifth, Seventh, and Eighth International Intercompari son of Environment al Dosimeters under the sponsorships listed in Table A-2.

Table A-3 lists results of the analyses on in-house spiked samples.

11 11 Table A-4 lists results of the analyses on in-house blank samples.

11 Attachment B lists acceptance criteria for spiked 11 samples.

Addendum to Appendix A provides expl4nation for out of limit results.

ADDENDUM TO APPENDIX A The following is an explanation of the reasons why certain samples were outside the control limit specified by the Environmental Protection Agency for the Interlabora-tory Comparison Program starting January 1987.

EPA Lab Code Analysis TIML Result Control Limit Explanation STr1-504 Sr-89 57.0+/-4.3 60.3-77.7 Milk had high fat content which Sr-90 32.0+/- 1.0 32.4-37 .6 made analyses difficult. Ad-di ti on of errors to TIML result would put values within EPA control limits. EPA al so had the same problem in analyzing its own sample.

STW-511 Ra-228 8.1+/-1.4 4.6-8.0 TIML results are usually within EPA control limits. Analysis

• of the next sar.iple was within EPA control limits. No further action is planned.

SHJ-516 Cr-51 80.3+/-17.5 61.3-78.7 Results in the past have been within EPA control limits and TIML will monitor the situation in the future.

STF-524 K 1010.7+/-158.5 1123.5-1336.5 Error in transferrance of data.

Correct data was 1105+/-33.

Results in the past have been within the limits and TIML will monitor the situation in the future.

STW-532 I-131 9.0+/-2.0 6.2-8.8 Sample recounted after 12 days.

The average result was 8.8+/-1. 7 (within EPA control limits).

The sample was recounted in order to check the decay *.

Results in the past have been within the limits and TIML will continue to monitor the situ-ation in the future.

ST\J-534 Co-60 63.3+/-1.3 41.3-58.7 High level of Co-60 was due to contamination of beaker.

Beaker was discarded upon dis~

cove ry of cont ami nation and sample was recounted. Recount r*esults were 53.2+/-3.6 and 50.9+/-2.4.

Appendix B Data Reporting Conventions B-1

Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.

2.0. Single Measurements Each. single measurement is reported as follows:

x +/- s where x = value of the measurement; s = 2o counting uncertainty (corresponding to the 95% confidence level}.

In cases where the activity is found to be below the lower limit of detection L it is reported as

<L where L = is the lower limit of detection based on 4.66a uncertainty for a background sample.

3.0. Duplicate Analyses 3.1. Individual results: x1 +/- s1 x2 +/- s2 Reported result: x +/- s where x = (1/2} (x1 + x2}

s = (1/2} ~sf+ s~

3.2. Individual results: <L1

<L2 Reported result: <L where L = lower of L1 and L2 3.3. Individual results: x+/- s

<L Reported result: x +/- s if x ~ L;

<L otherwise B-2

4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from _all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average i and standard deviation(s) of a set of n numbers x1, x2, * . . xn are defined as fallows:

-X = -1l ; X n

s*= E (x-i)2 n-1 4.2 Values below the highest lower limit of detection are not included in the average.

4.3 If all of the values in the averaging group are less than the highest LLD, the highest LLD is reported.

4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.

4.5. In rounding off, the following rules are followed:

4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged. As an example, 11.443 is rounded off to 11.44.

4.5.2 If the figure following those to be retained is greater than 5, the figure is dropped, and the last retained figure is raised by 1. As an example, 11.446 is rounded off to 11.45.

4.5.3. If the figure following those to be retained is 5, and if there are no figures other than zeros beyond the five, the figure 5 is dropped, and the last-place figure retained is increased by one if it is an odd number or it is kept unchanged if an even number. As an example, 11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42.
