3.0 RADIATION ENVIRONMENTAL MONITORING PROGRAM (REMP) j j
3.1 Procram Desien and Data InteroretatiRB 1
Tl e purpose of the Radiation Environmental Monitoring Program (REMP) at the i
Monticello 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 (TLD's).
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 nuc! car 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 monitormg i
program at the Monticello 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 significantly larger than that at the control location. The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising from other sources.
An additional interpretive technique involves analyses for specific radionuclides present in environmental samples collected from the Plant site. The Plant's monitoring program i
includes analyses for tritium and iodine-131. Most samples are also analyzed for gamma-emitting isotopes with results for the following groups quantified: zirconium-95, i
cesium-137, cerium-144, beryllium-7, and potassium-40. The first three 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 produced 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 as radiological impact indicators.
The other group quantified consists of niobium-95, ruthenium-103 and -106, cesium-134, l
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 3
i Emgram Design and Data Interpretation (continued) j environment has been atmospheric nuclear testing. Nuclides of the final group, I
manganese-54, iron-59, cobalt-58 and -60, and zinc-65, are activation products and l
l 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 are employed in interpreting the data. Current radiation levels are compared with previous levels, including those measured before the plant became operational. Results of the Plant's l
l 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.
I 3.2 Program Description The sampling and analysis schedule for the Radiation Environmental Monitoring l
Program (REMP) at the Monticello Plant 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 l
4 sector relative to the reactor site. To assure that sampling is carried out in a reproducible manner, detailed sampling procedures have been prescribed (Monticello Generating Plant REMP Surveillances, Current Revision). Maps of sampling locations are included in Appendix D.
l To monitor the air environment, airborne particulates are collected on membrane filters l
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 l
and counted weekly. Particulate filters are analyzed for gross beta activity and charcoal l
filters for iodine-131. Quarterly composites of particulate filters from each location are gamma-scanned on a HP Ge or Ge(Li) detector. One of the five locations is a control (M-1), and four are indicators (M-2, M-3, M-4, M-5). One of the indicators is located in the geographical sector expected to be most susceptible to any atmospheric emissions from the Plant (highest D/Q sector).
As a " Lessons Learned" cornmitment, ambient gamma radiation is monitored at thirty-seven (37) locations, using CaSO4:Dy dosimeter with four sensitive areas at each location: fourteen (14) in an inner ring in the general area of the site boundary, sixteen (16) in the outer ring within 4-5 mile radius, six (6) at special interest locations and one control location,11.1 miles distant from the plant. They are replaced and measured quarterly. Also, a complete emergency set of TLD's for alllocations is placed in the field l
at the same time as regular sets. The emergency set is returned to TBEESML quarterly for annealing and repackaging.
Milk samples are collected monthly from three farms (two indicator and one control).
There are currently only two milk producers within the indicator area. The milk is collected biweekly during the growing season (May - October), because the milk animals may be on pasture. All samples are analyzed for iodine-131 and gamma-emitting isotopes.
Leafy green vegetables (cabbage) are collected annually from the highest D/Q garden and a control location and analyzed for iodine-131. Corn and potatoes are collected 4
l
l Program Description (continued) i l
annually only if the field is irrigated by water in which radioactive effluent has been i
discharged. Analysis is for gamma-emitting isotopes.
The terrestrial environment is also monitored by collection of well water from four locations on a quarterly basis. All samples are analyzed for tritium and gamma-emitting l
isotopes.
l River water is collected weekly at two locations, one upstream o.he plant and one downstream. Monthly composites are analyzed for gamma s.mitting isotopes.
Quarterly composites are analyzed for tritium.
Drinking water is collected weekly from the City of Minneapolis water supply, which is taken from the Mississippi River downstream of the Plant. Monthly composites are analyzed for gross beta, iodine-131, and gamma-emitting isotopes. Quarterly composites are analyzed for tritium.
The aquatic environment is also monitored by semi-annual upstream and downstream collections of fish, invertebrates, and shoreline sediments. Shoreline sediment is also collected semi-annually from one downstream recreational location. All samples are analyzed for gamma-emitting isotopes.

' 3.4 Laboratory Procedures The iodine-131 analyses in milk and drinking water were made using a sensitive radiochemical procedure which involves separation of the iodine using an ion-exchange j
method and solvent extraction and subsequent beta counting.
All gamma-spectroscopic at alyses were performed with an HPGe or Ge(Li) detector.
Levels of iodine-131 in cabbge and natural vegetation were determined by HPGe or Ge(Li) spectrometry. The concentrations of airborne iodine-131 in charcoal samples were measured by HPGe or Ge(Li) spectrometry.
Tritium was determined by a liquid scintillation technique.
Analytical procedures used by the Teledyne Brown Engineering Environmental Services, Midwest Laboratory are on file and are available for inspection. 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 Brown Engineering Environmental Services, Midwest Laboratory has a comprehensive quality control / quality assurance program designed to assure the reliability of data obtained. Details of TBEESML's QA Program are presented elsewhere (Teledyne Isotopes Midwest Laboratory,1992). The TBEESML QA Program includes participation in Interlaboratory Comparison (crosscheck) Programs. Results obtained in crosscheck programs are presented in Appendix A.
3.5 Program Modifications There were no program modifications made during 1996.
3.6 Land Use Census In accordance with the Technical Specifications 4.16 Paragraph B1, a land use census shall be conducted and shall identify the location of the nearest milk animal, the nearest residence, and the nearest garden of greater than 500 ft2 producing fresh leafy vegetables, in each of the 16 meteorological sectors within a distance of 5 miles. The census shall also identify the locations of all milk animals and all 500 ft2 or greater gardens producing broad leaf vegetation in each of the meteorological sectors within a distance of three miles. This census shall be conducted at least once per year between the dates of May 1 and October 31. New locations shall be added to the radiation environmental monitoring program within 30 days and sampling locations having lower i
calculated doses or a lower dose commitment may be deleted from this monitoring j
program after October 31 of the year in which the land use census was conducted. The i
1996 land use census was conducted between August 28 and September 16,1996. No changes to the highest D/Q garden, residence or dairy locations from the 1995 census were identified. The highest D/Q locations remained; Resident (0.6 mi./SW), Garden (0.7 nii./SSW), and Dairy (3.7 mi./WNW). Detailed land use census data are l
contained in the Land Use Census and Critical Receptor Report, October 14, 1996, Monticello Nudear Generating Plant, Radiological Services Department.

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 Atmosoheric Nuclear Detonations and Nuclear Accidents There were no reported atmospheric nuclear tests in 1996. The last reported test was conducted by the People's Republic of China on October 16,1980. The reported yield was in the 200 kiloton to 1 megaton range.
There were no reported accidents at nuclear facilities in 1996.
4.2 Summary of Preocerational Data The following constitutes a summary of preoperational studies conducted at the Monticello Nuclear Generating Plant during the years 1968 to 1970, to determine background levels expected in the environment, and provided, where applicable, as a means for comparison with present day levels. Strict comparisons, however, are difficult to make, since background levels of radiation were much higher in these years due to radioactive fallout from the atmosphere. Gross beta measurements in fallout averaged 20,600 pCi/m2 in 1969 and 12,000 pCi/m2 in 1970. These levels are reflected throughout the various media tested.
In the air environment, ambient gamma radiation (TLDs) averaged 9.1 mR/4 weeks during preoperational studies (1970). Gross beta in air particulates in 1969 and 1970 averaged 0.20 pCi/m3. Present day levels have stabilized at around 0.025 pCi/m,
3 Airborne radiciodine remained below detection levels.
In the terrestrial environment of 1968 to 1970, milk, agricultural crops, and soil were monitored. In milk samples, low levels of Cs-137 and Sr-90 were detected. Cs-137 levels averaged 16.7 pCi/L. Soybean crop measurements in 1969 averaged 35.5 pCi/g for gross beta and 0.3 pCi/g for Cs-137. Gross beta measured in soil averaged 51.7 pCi/g. Present day measurements for cesium-137 are below detection levels in milk and agricultural crops.
The aqueous environment was monitored by testing of river water, bottom sediments, fish, aquatic vegetation, and periphyton. Specific location comparison of drinking, river, and well water concentrations for tritium and gross beta are not possible. However, tritium background levels, measured at seven sesarate locations from 1968 to 1970, averaged 970 pCi/L. Present day environmental samples measure below detection l
levels. Values for gross beta, measured from 1968 to 1970, averaged 9.8 pCi/L in upstream and downstream Mississippi River water,4.4 pCi/L for well waters, and 18.6 aCi/L for lake waters. Gamma emitters were below the lower limit of detection (LLD).
En shoreline sediments, gross beta background levels in 1970 averaged 49.8 pCi/g for both upstream and downstream samples. Cs-137 activity averaged 0.10 pCi/g for both upstream and downstream samples. The lower levels of Cs-137 occasionally observed today can still be attributed to residual activity from atmospheric fallout.

Summarv of Preocerational Data (continued)
Gross beta levels in fish flesh averaged 5.3 pCi/g in 1968 and 1969. Cs-137, measured in 1969 and 1970, averaged 0.044 pCi/g. Gross beta background levels, in 1970, for l
aquatic vegetation, algae, and periphyton samples measured 86.7 pCi/g, 76.5 pCi/g, and 28.1 pCi/g respectively.
4.3 Procram Findines Results obtained show background levels of radioactivity in the environmental samples collected in the vicinity of the Monticello Nuclear Generating Plant in 1996.
Ambient Radiation (TLD's)
Ambient radiation was measured in the general area of site boundary, at outer ring 4 - 5 mi. distant from the Plant, at special interest areas and at one control location. The means were similar for both inner and outer rings (14.0 and 13.5 mR/91 days, respectively). The mean for speciallocations was 13.9 mR/91 days. The mean for the control location was 12.7 mR/91 days. The differences are not statistically significant.
The dose rates measured at the inner and outer ring locations and the control location were similar to those observed in 1984 (13.6 and 13.4 mR/91 days, respectively); in 1985 (12.7 and 12.4 mR/91 days, respectively); in 1986 (14.3 and 12.8 mR/91 days, respectively); in 1987 (15.4 and 14.2 mR/91 days, respectively) in 1988 (14.7 and 13.0 mR/91 days, respectively); in 1989 (15.2 and 14.1 mR/91 days, respectively); in 1990 (16.2 and 15.2 mR/91 days, respectively); in 1991 (15.5 and 15.0 mR/91 days, i
respectively); in 199.2 (15.1 and 14.4 mR/91 days ); in 1993 (15.8 and 15.3 mR/91 days, respectively), in 1994 (14.3 and 13.2 mR/91 days, respectively) and in 1995 (14.0 and 12.7 mR/91 days, respectively). No plant effect on ambient gamma radiation was indicated (Figure 5-1).
Airborne Particulates The average annual gross beta concentration in airborne particulates was identical at 3
both indicator and control locations (0.023 pCi/m ) and were similar to levels observed in 1984 (0.025 and 0.024 pCi/m3, respectively), 1985 (0.025 and 0.024 pCi/m3, respectively), 1986 (0.026 pCi/m3),1987 (0.026 pCi/m3), in 1988 (0.030 pCi/m3), in 1989 (0.027 and 0.026 pCi/m3, respectively), in 1990 (0.023 pCi/m3), in 1991 (0.024 pCi/m3), in 1992 (0.023 pCi/m3),1993 (0.024 and 0.023 pCi/m3, respectively), in 1994 (0.023 and 0.024 pCi/m3, respectively) and in 1995 (0.024 and 0.025 pCi/m3, respectively). The data for 1986 does not include the results from May 19 to June 9, 1986, which were influenced by the accident at Chernobyl. (Figure 5-2).
A s aring peak in beta activity had been observed almost annually for many years (Wi son et al.,1969). It had been attributed to fallout of nuclides from the stratosphere (Gold et al.,1964). It was pronounced in 1981, occurred to a lesser degree in 1982, and did not occur in 1983 through 1996. 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 months of January and December, and the first and fourth quarters, as in 1984 through 1996 (exclusive of the period between May 19,1986 and June 9,1986).
Two pieces of evidence indicate conclusively that the elevated activity observed during i-the first and fourth quarters was not attributable to the Plant operation. In the first 8
l l
t l
Airborne Particulates (continued) q place, elevated activity of similar size occurred simultaneously at both indicator and control locations. Secondly, an identical pattern was observed at the Prairie Island j
Nuclear Generating Plant, about 100 miles distant from the Monticello Nuclear Generating Plant (Northern States Power Company,1997b).
l
- Gamma spectroscopic analysis of quarterly composites of air particulate filters yielded similar results for indicator and control locations. Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation (Arnold and Al-Salih,1955) was detected in all samples, with an average of 0.080 pCi/m3 at both indicator and control locations. All other gamma-emitting isotopes were below their respective LLD limits.
Airbome lodine Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 0.07 pCi/m3 in all samples.
Milk Iodine-131 results were below the detection limit of 1.0 pCi/L in all samples.
Cesium-137 results were below the LLD level of 15 pCi/L in all samples.
No other gamma-emitting isotopes except naturally-occurring potassium-40, were detected in any of the 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 1996 show no radiological effects of the plant operation.
River Water and Drinkine Water Tritium was below the LLD of 330 pCi/L in all samples. Gross beta in Minneapolis drinking water averaged 2.1 pCi/L and was less than or similar to average levels observed in 1977 (3.4 pCi/L), in 1978 (3.8 pCi/L), in 1979 (3.4 pCi/L), in 1980 (3.2 pCi/ L),-in 1981 (3.5 pCi/L), in 1982 (2.9 pCi/L), in 1983 (3.3 pCi/L), in 1984 (2.8 pCi/L), in 1985 (2.8 pCi/L), in 1986 (2.5 pCi/L), in 1987 (2.4 pCi/L), in 1988 (2.7 pCi/L), in 1989 (2.6 pCi/L), in 1990 (2.2 pci/L), in 1991 (2.9 pCi/L), in 1992 (2.1 pCi/L), in - 1993 (2.6 pCi/L), in 1994 (2.0 pCi/L) and in 1995 (2.3 pCi/L).
Comparisons with gross beta data reported by EPA for Minneapolis drinking water sample collected in 1975,1976,1977. and 1978 indicates that concentrations of these nuclides are remaining fairly constant and are in the range of drinking water levels in other parts of the country (U.S. Environmental Protection Agency, 1975,1976,1977, 1978). Gamma-emitting isotopes were below detection limits in all surface water samples. There was no indication of a plant effect.
l 9
Well Water The tritium level was below the LLD level of 330 pCi/L in all samples. All gamma isotopic results were below detection limits. There was no indication of a plant effect.
1 Crops Two (2) samples of cabbage were collected in September and analyzed for iodine-131.
The I-131 level was below 0.023 pCi/g wet weight in both samples. There was no t
indication of a plant effect. There were no crops irrigated from the Mississippi River l
within 5 miles of the plant in 1996; therefore, no corn or potato samples were collected for analysis from irrigated fields.
Eish l
Fish samples were collected in April and October. Flesh was separated from the bones and gamma-scanned. Potassium-40, the naturally-occurring isotope, was found to be similar in upstream and downstream samples (2.98 and 2.84 pCi/g wet weight, respectively). All gamma-emitting isotopes were below their respective LLD levels.
There was no indication of a plant effect.
Invertebrates Two samples were collected in May and two in October. The samples were analyzed for gamma-emitting isotopes. All isotopes were below detection limits. There was no indication of a plant effect.
l Shoreline Sediments Upstream, downstream and downstream recreational area shoreline sediment collections were made in May and October and analyzed for gamma-emitting isotopes.
Cesium-137 was detected in one downstream sample, averaging 0.07 pCi/g dry weight, and in both recreational area samples, averaging 0.14 pCi/g dry weight, indicating the influence.of fallout deposition. Similar levels of activities and distribution were observed in 1978-1995. The only other gamma-emitting isotope detected was naturally-
- occurring potassium 40. There was no indication of a plant effect.

Interlaboratory Comoarison Program Results l
Teledyne's Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's 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 concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laborateries 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 and air filters during the past twelve months. Data for previous years is available upon request.
'Ihis program is conducted by the U.S. Environmental Protection Agency Intercomparison and Calibratiori Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, t
Nevada.
The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs) since 1976 via various InternationalIntercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2.
Teledyne testing results are also listed.
Table A-3 lists results of the wnalyses on in-house " spiked" samples for the past twelve months. Data for previous years available upon request.
Table A-4 lists results of the analyses on in-house " blank" samples for the past twelve months. Data for previous years available upon request.
Table A-5 lists results of the in-house " duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.
The results in Table A-6 were obtained through participation in the mixed analyte performance evaluation program.
The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.
l Attachment A lists acceptance criteria for " spiked" samples, Out-of-limit results are explainad directly below the result.

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 i
Each single measurement is reported as follows:
j xts where x = value of the measurement; s = 20 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
<L l
where L = the lower limit of detection based on 4.66o uncertainty for a background sample.
3.0. Duplicate analyses 3.1 Individual results:
x1 i s1 x2 i s2 Reported result:
x' s
where x = (1/2)(x1 + x2) s = (1/2) k s + s!
2 3.2. Individual results:
<L1
<L2 Reported result: <L where L = lower of L and L2 1
3.3. Individual results: x i s
<L Reported result:
x i s if x 2 L; l
<L otherwise l

4.0. Computation of Averages and Standard Deviations l
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 xi, x2... x are n
defined as follows:
i I
x=fEx E (x-x)2 s=
n-1 i
4.2 Values below the highest lower limit of detection are not included in the average.
l 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:
l 4.5.1. If the figure following those to be retained is less than 5, the figure is l
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 equal to or greater than 5, the i
figure is dropped and the last retained figure is raised by 1.
As an example,11.445 is rounded off to 11.45.
