1.0 INTRODUCTION

This report summarizes and interprets results of the Radiation Environmental Monitoring Program (RD4P) conducted by Teledyne Isotopes Midwest Laboratory at the Prairie Island Nuclear Generating Plant, Red Wing, Minnesota, during i the period January - December, 1988. This program monitors the levels of radioactivity in the cir, terrestrial, and aquatic environments in order to assess the $mpact of the plant on its surroundings.

Tabulations of the individual analyses made during the year are not included in this report. These data are included in a reference document (Teledyne Isotopes Midwest Laboratory,1988) available at Northern States Power Company, Nuclear Generation Department.

Prairie Island Nuclear Generating Plant is located on the Mississippi River in Goodhue County, Minnesota, and operated by Northern States Power Company. The plant has two 550 MWe pressurized water reactors. Unit 1 achieved initial criticality on 1 December 1973. Commercial operation at full power began on 16 December 1973. Unit 2 achieved initial criticality on 17 December 1974.

Commercial operation at full power began on 21 December 1974.

3.0 RADIATION ENVIRONMENTAL MONITORING PROGRAM (REMP) 3.1 Program Design and Data Interpretation The purpose of the Radiation Environmental Monitoring Program (REMP)~ at the' Prairie Island Nuclear Generating Plant is to assess the impact of the plant on its environment. . For this purpose, samples are collected from ' the air, terrestrial', and aquatic environments and analyzed for radioactive content. In addition, ambient gamma radiation levels are monitored by thermoluminescent dosimeters (Ti.Ds). ,

Sources of environmental radiation include the following:

(1)~ - Natural background radiation arising from cosmic rays and primordial radionuclides; (2) Fallout from atmospheric nuclear detonations; (3) Releases from nuclear power plants; (4) Industrial and medical radioactive waste; and (5) Fallout from nuclear accidents.

In interpreting the data, effects due to the plant must be distinguished from those due to other sources.

A major interpretive aid in assessment of these effects is the design of the monitoring program at the Prairie Island Plant which is based on the indicator-control concept. Most types of samples are collected both at indicator locations (nearby, downwind, or downstream) and at control locations (distant, upwind, or upstream). A plant effect would be indicated if the radiation level at an indicator location was signifi-cdnlly Idrger than that at the control l ocation. The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising fron other sources.

An additional interpretive technique involves analyses for specific radionuclides present in the environmental samples collected from the plant site. The plant's monitoring program includes analyses for tritium and iodi ne-131. Most samples are also analyzed for gamma-emitting isotopes with resJlts for the following groups quantified: zirconium-95, 3

l i

cesium-137, cerium-144, beryll i um-7, and potassium-40. The first three 1 gamma-emitting isotopes were selected as radiological impact indicators because of the _ different characteristic proportions in which they appear in the fission product mix produced by a nuclear reactor and that pro-duced by a nuclear detonation. Each of the three isotopes is produced in roughly equivalent amounts by a reactor: each constitutes about 10% of the total activity of fission products 10 days after reactor _ shutdown.

On the other hand,10 days after _a nuclear explosion, the contributions of zirconium-95, cerium-144, and cesium-137 to the activity of the resulting debris are in the approximate ratio 4:1:0.03 (Eisenbud,1963).

Beryllium-7 is of cosmogenic origin and potassium-40 is a naturally-occurring isotope. They were chosen as calibration monitors and should not be considered radiological impact indicators.

The other group quantified consists of niobium-95, ruthenium-103, and

-106, cesium-134, barium-lanthanum-140, and cerium-141. These isotopes are. released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmospheric nuclear testing. Nuclides of the final group, manganese-54, iron-59, cobal t-58, and -60, and zi nc-65, are activation products and arise from . activation of corrosion products. They- are typical components of a nuclear power plant's effluents, but are not produced in significant quantities by nuclear detonations.

Other means of distinguishing sources of environmental radiation can be employed in interpreting the data. Current radiation levels can be compared with previous levels, including those measured before the Plant i became operational. Results of the plant's monitoring program can be '

related to those obtained in other parts of the world. Finally, results can be related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations.

3.2 Program Description The sampling and analysis schedule for the environmental radiation monitoring program at Prairie Island is summarized in Table 5.1 and briefly reviewed below. Table 5.2 defines the sampling location codes used in Table 5.1 and specifies for each location its type (indicator or control) and its distance, direction, and sector relative to the reactor -

site. To assure that sampling is carried out in a reproducible manner, detailed sampling procedures have been prescribed (Teledyne Isotopes Midwest Laboratory, 1987).

To monitor the air environment, airborne particulate are collected on membrane filters by continuous pumping at five locations. Also, airborne iodine is collected by continuous pumping through charcoal filters at all of these locations. Filters are changed and counted weekly. Particulate filters are analyzed for gross beta activity and charcoal filters for 4

J

i i odi ne-131. A monthly composite of all particulate filters is gamma-scanned on an 'HP Ge or Ge(Li.) detector. One of the five locations is a control (P-1), a'nd four are indicator (P-2, P-3, P-4, and P-6). One of the indicators (P-3) is located near. the residence expected to be most susceptible to any atmospheric. emissions ' from the plant (highest D/Q residence).

As' a " Lessons Learned" commitment, ambient gamma radiation is monitored at thirty-two (32) locations, using CaSo4:Dy dosimeter with four sensi-tive areas at each location: ten (10) in an inner "ing in the general area of the site boundary, fifteen (15) .in the outer ring within 4-5 mile radius, six (6) at special interest locations and one control. location, 11.1' niles distant from the plant. They are replaced and measured quarterly. Al so , a complete . emergency set of TLDs for all locations is placed in the field at the same time as regular sets. The emergency set

.is returned to TIML quarterly for annealing and repackaging.

Milk samples are collected monthly from five farms (four indicator and one controi). If the milch animals are on pasture; the milk is collected biweekly during the growing season (May - November). All samples are analyzed for iodine-131 and gamma-emitting isotopes.

For additional monitoring of the terrestrial environment, leafy green vegetables (cabbage) are collected annually from the highest D/Q garden and a control location (P-25) and analyzed for iodine-131. Corn is collected annually only' from fields irrigatec with river water and a control location (P-25) and analyzed for gamma-emitting isotopes. Al so ,

well water is collected quarterly from four locations and analyzed for tritium and gamma-emitting isotopes.

River water is collected weekly at two locations, one upstream of the plant (P-5) and one downstream (P-6, Lock and Dam No. 3). Monthly composites are analyzed for gamma-emitting isotopes. Quarterly compo-sites are analyzed for tritium.

Drinking water is collected weekly from the City of Red Wing well.

Monthly composites are analyzed for gross beta, i odi ne-131, and gamma-emitting isotopes. Quarterly composites are analyzed for tritium, The aquatic environment is also nonitored by semi-annual upstream and downstream collections of fish, periphyton or invertebrates, and bottom sediments. Shoreline sediment is collected semi-annually from one location. All samples are analyzed for gamma-emitting isotopes.

3. 3 Program Execution The Program was executed as described in the preceding section with the following exceptions:

1. The TLD data for the first quarter' of 1988 for. Location P-05S was not available because TLD was lost in the fiel d.

P Deviations from the program are summarized in Table 5.3.

3.4 ' Laboratory Procedures All iodine-131 analyses in milk and drinking water were made by using a sensitive radiochemical procedure which involves separation of the element by use of an ion-exchange resin and subsequent beta counting.

All gamma-spectroscopic analyses were performed with an HP Ge or Ge(Li)..

detector. Levels of iodine-131 in cabbage were determined by HP Ge or Ge(Li) spectrometry. Levels of airborne iodine-131 in charcoal sampl es. j were measured by HP Ge or Ge(Li) spectrometry.

Tritium . levels were determined by liquid' scintillation technique.

Analytical procedures used by .the Teledyne Isotopes Midwest Laboratory i are specified in detail elsewhere (Teledync Isotopes Midwest Laboratory, !

1985). Procedures are. based on those prescribed by the National Center for Radiological Health of the U. S. Public Health Service (U. S. Public Health Service, 1967 ) and by the Health and Safety Laboratory of the U. S. Atomic Energy Commission (U. S. Atomic Energy Commission, 1972).

Teledyne Isotopes Midwest Laboratory has a comprehensive quality control /

quality assurance program designed to assure the reliability of data obtained. Details of TIML's Quality Assurance Program are presented elsewhere (Teledyne Isotopes Midwest Laboratory,1988). The TIML Quality Assurance Program includes participation in Interlaboratory Comparison (Crosscheck) Programs. Results obtained in crosscheck programs are presented in Appendix A.

3.5 Program Modifications During the growi ng season, milk producers were monitored to determine when the dairy animals were on pasture or fresh cut feed. The frequency of milk samples was increased to semimonthly at one indicator location (Gustafson) and one control location (Kinneman) during the period because animals were on pasture or fresh cut feed.

3.6 Land Use Census In accordance with Technical Specification 4.10, paragraph B1, a land use census is conducted in order to identify the location of the nearest milk i

i animal the nearest residence, and the nearest garden of greater than 3 500 ft$ producing fresh leafy vegetables in eacn of the 16 meteorological j sectors within a distance of 5 miles. This census is conducted at least I l once per 12 months between the dates of May 1 and October 31. New- i locations are added to the radiological environmental monitoring program within 30 days, and sampling locations having lower calculated doses or a lower dose commitment may be deleted from this monitoring program after !

October 31 of the year in which the land use census was conducted. i 1

This land use census insures the updating of the radiation environmental monitoring program should sampling locations change within the 5 mile radius from the plant.

The 1988 Land Use Census was completed on July 8,1988. This census did not identify any locations of exposure pathways different from those used in the program during the first six months of the year. Milk and garden sample locations did not change due to the requirements of the land use Census.

4.0 RESULTS AND DISCUSSION All of the scheduled collections and analyses were made except those listed in Table 5.3.

. All results are summarized in Table 5.4 in a format recommended by the Nuclear Regulatory Commission in Regulatory Guide 4.8. For each type of analysis of each sampled medium, this . table lists the mean and range for all . indicator locations and for all. control locations. The locations with the highest mean and range are also shown.

4.1 Atmospheric Nuclear Detonations and Nuclear Accidents There were no reported atmospheric nuclear tests'in 1988. The last reported test was conducted on October 16, 1980 by the People's Republic of China. .The reported yield was in the 200 kiloton to 1 megaton range.

There were no reported accidents at nuclear reactor facilities in 1988.

4.2 Program Findings Results obtained show background levels of radioactivity in the environ-mental samples collected in the vicinity of the Prairie Island Nuclear Generating Plant in 1988.

Ambient Radiation (TLDs) h Ambient radiation was measured in the general area of site boundary, at l outer ring 4 - 5 mi distant from the Plant, at special interest areas, l~ and at one control l ocation. The means ranged from 14.9 mR/91 days at inner ring locations to 15.8 mR/91 days at outer ring locations. The mean at special locations was 14.4 mR/91 days and 16.0 mR/91 days at the control location. The dif ferences are not statistically significant.

The dose rates measured at all indicator and control locations were similar to those observed in 1978 (12.1 and 15.1 mR/91 days, respec-tively); in 1979 (12.6 and 15.3 mR/91 days, respectively); in 1980 (11.2 and 13.5 mR/91 days, respectively),; in 1981 (13.0 and 14.5 mR/91 days, respectively); in 1982 (12.0 and 13.0 mR/91 days, respectively),; in 8

L .

1983 (13.0 and 14.9 mR/91 days, respectively); in 1984 (13.9 and 15.3 i mR/91 days, respectively); in 1985 (13.9 and 15.3 mR/91 days, respec-tively); in 1986 (16.6 and 17.0 mR/91 days, respectively) and in 1987 (15.4 and 16.0 mR/91 days, respectively). No plant effect on ambient gamma radiation was indicated.

l Airborne Particulate The average annual gross beta concentration in airborne particulate was identical at both indicator and control locations (0.030 pCi/m3) and was slightly higher than the levels observed in 1982 (0.026 1983 l

(0.023 1984 (0.024 pC1/m3), 1985 (0.025 pCi/m3) 1986 ,pCi/m3)

(0.025, pC1/m3) ,pC1/m3) ,and 1987 (0.024 pCi/m3).

The average of 0.025 pCi/m3 for 1986 does not include the results from May 19 to June 9, 1986, which were influenced by the accident at Chernobyl.

A spring peak in beta activity had been observed almost annually for many years (Wilson et al., 1969). It had been attributed to fallout of nuclides from tFe stratosphere (Gold et al., 1964). It was pronounced in 1981, occurred to a lesser degreT f51982, and did not occur in 1983, 1984, 1985, 1987 or 1988. In 1986, the spring peak could not be identified because it was overshadowed by the releases of radioactivity from Chernobyl . The highest averages for gross beta were for the month of December and the fourth quarter, as in 1983, 1984, 1985, 1986 (ex-clusive of the period between May 19, 1986 and June 9, 1986) and 1987.

Two pieces of evidence indicate conclusively that the elevated cctivity observed during the fourth quarter was not attributable to the Plant op-eration. In the first place, elevated activity of similar size occurred simultaneously at both indicator and control locations. Secondly, an identical pattern was observed at the Monticello Nuclear Generating Plant, about 100 miles distant from the Prairie Island Nuclear Generating Plant (Northern States Power Company,1988).

Gamma spectroscopic analysis of quarterly mmoosites of air particulate filters yiel ded similar results for inu. ator and control locations.

Berylliun-7, which is produced continuously in the upper atmosphere by cosmic radi atic'1 ( Arnol d and Al-Sal i h, 1955), was detected in all samples. All other gamma-emitting isotopes were below their respective LLD limits.

Airborne Iodine .

Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.07 pCi/m3 in all samples.

9 I

Milk Iodine-131 results were below the detection limit of 1.0 pCi/l in all sempl es.

Cs-137 results were below the LLD level of 15 pCi/l in all samples. No other gamma-emitting isotopes, except potassium-40, were detected in any milk samples. This is consistent with the finding of the National Center for Radiological Health that most radiocontaminants in feed do not find their way into milk due to the selective metabolism of the cow. The common exceptions are radioisotopes of potassium, cesium, strontium, barium, and iodine (National Center for Radiological Health,1968).

In summary, the milk data for the 1988 show no radiological effects of !

the plant operation.

Drinking Water In drinking water from the City of Red Wing well, tritium activity was below the LLD level of 330 pCi/l in all camples. Iodine-131 activity was ;

also below the LLD level at 1.0 pCi/l in all samples. As with the other well water sampl es , all analyses for gamma-emitting isotopes yielded results below detection limits. Gross beta averaged 8.0 pCi/1 and was similar to the levels observed in 1979 (10.5 pCi/1),1980 (11.8 pCi/1),

1981 (10.7 pCi/1),1982 (8.9 pCi/1),1983 (8.0 pCi/1),1984 (7.9 pCi/1), i 1985 (7.1 pCi/1), 1986 (6.8 pCi/1) and 1987 (7.9 pCi/1). I I

i River Water At the upstream and downstream collection sites, quarterly composite i tritium levels were below the LLD level of 330 pCi/1 in all sampl es.

River water was also analyzed for gamma-emitting isotopes. All gamma-emitting isotopes were below their respective detection limits. There was no indication of a plant effect.

Well Water At the control well P-25, Kinneman Farm and three indicator wells (P-8, Community Center; P-10, Lock and Dam No. 3; and P-9, Plant Well No. 2) no tritium was detected above LLD level of 330 pC1/1 in all samples.

Gamma-emitting isotopes were below the detection limits in all sampl es.

a Crops Two samples of cabbage were collected in August and analyzed for I-131.

The I-131 level was below 0.034 pCi/g wet weight in both samples. There was no indication of a plant.effect.

Fish Fish samples were collected in June, September, and October,1988. The only isotope detected was naturally-occuring potassium-40 and there was no significant difference between upstream and downstream results. There was no indication of a plant effect.

Aquatic Insects or Periphyton Aquatic insects (invertebrates) or periphyton were collected in June, May, and September,198G. The samples were analyzed for gamma-emitting isotopes. All gamma-emitting isotopes were below their respective LLDs.

No plant effect was indicated.

Bottom and Shoreline Sediments Sediment collections were made in April and September,1988. The samples were analyzed for gamma-emitting isotopes.

Cs-137 was detected in two bottom sediment upstream samples and averaged 0.083 pC1/g dry weight.

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 programs 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. The purpose of such a program is to provide an independent check on the laboratory'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
. limits 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. Environmental 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) during the period 1976,1977,1979,1980,1984, and 1985-1986 through partici-pation in the Second, Third, Fourth, Fifth, Seventh, and Eighth International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2.
Table A-3 lists results of the analyses on in-house spiked samples.
Table A-4 lists results of the analyses on in-house " blank" samples.
Attachment B lists acceptance criteria for " spiked" samples.
Addendum to Appendix A provides explanation for out of limit results.

I-Data Reporting Conventions i
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 mea'surement is reported as follows:
xis where x = value of the measurement; s = 2a 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 i s1 x2
~~52 Reported result: xis where x = (1/2)'(x1 + x2) s=(1/2) s 2+sf 3.2. Individual results: <L1~~
<L2 Reported retult: <L where L = lower of L1 and L2 3.3. Individual results: xis
<L Reported result: x i s if x > L;
<L otherwise B-2

l l
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 x and standard deviation (s) of a set of n numbers x1, x2 Xn are defined as follows:
x= hex s= E (*~ )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.

ADDENDUM TO APPENDIX A l
l The following is an explanation of the reasons why certain samples were outside the I
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 STit-504 Sr-89 - 57.024.3 60.3-77.7 Milk had high fat content which Sr-90 32.011.0 32.4-37.6 made analyses difficult. Ad-dition of errors to TIML result would put values within EPA control limits. EPA also hed the same problem in analyzing its own sample.
STW-511 Ra-228 8.121.4 4.6-8.0 TIML results are usually within EPA control limits. Analysis of the next sample was within '
EPA control limits. No further action is planned.
STW-516 Cr-51 is.3217.5 61.3-78.7 Results in the past have been within EPA control limits and TIML will monitor the situation in the future.
ST F-524 K 1010.72158.5 1123.5-1336.5 Error in transferrance of data.
Correct data was 1105233.
Results in the past have been within the limits and TIML will monitor the situation in the future.
STW-532 I-131 9.012.0 6.2-8.8 Sample recounted after 12 days.
The average result was 8.821.7 (within EPA control limits).
The sample was recounted in order to check the decay.
Results in the past have been
{
within the limits and TIHL will j continue to monitor the situ-ation in the future.
STW-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-c ove ry of cont ami nation and sample was recounted. Recount results were 53.223.6 and 50.922.4.

Maximum pennissible concentrations of radioactiv'ty in air and water above natural background in unrestrictcJ areas.a Air Water Gross alpha 3 pCi/m3 Strontium-89 3,000 pCi/1 Gross beta 100 pCi/m3 Strontium-90 300 pCi/1 Iodine-131b 0.14 pCi/m3 Cesium-137 20,000 pC1/1 Barium-140 20,000 pC1/1 Iodine-131 300 pCi/1 Potassium-40c 3,000 pCi/1 Gross alpha 30 pCi/1 Gross beta 100 pCi/1 Tritium 3 x 106 pCi/1 a
Taken from Code of Federal Regulations Title 10, Part 20 Table 11 and appro-priate footnotes. Concentrations may be averaged over a period not greater than one year.
b From 10 CFR 20 but adjusted by a f actor of 700 to reduce the dose resulting from the air-grass-cow-milk-child pathway.
