1.0 INTRODUCTION

This report summarizes and interprets results of the Environmental Radiological Monitoring Program conducted by Teledyne Isotopes Midwest Laboratory at the Duane Arnold Energy Center, Cedar Rapids,

Iowa, during the period January December, 1989.

This Program monitors the levels of radioactivity in the air, terrestrial, and aquatic environments in order to assess the impact of the Plant on its surroundings.

Tabulation of the individual analyses made during the year are included in Part II of this report.

Duane Arnold Energy Center (DAEC) is located in Linn County on the Cedar River, Iowa, and is operated by Iowa Electric Light and Power Company.

Duane Arnold Nuclear Station is a 565.7 MW(e) boiling water reactor.

Initial criticality was attained on 23 March 1974.

The reactor reached 100% power on 12 August 1974. Commercial operation began on 1 February 1975.

SUMMARY

The Environmental Radiological Monitoring Program required by the U.S. Nuclear Regulatory Commission (NRC) Technical Specifications for the Duane Arnold Nuclear Generating Plant is described.

Results for 1989 are summarized and discussed.

Program findings show background levels of radioactivity in the environmental samples collected in the vicinity of the Duane Arnold Energy Center. No effect on the environment due to the operation of the Duane Arnold Nuclear Plant is indicated.

3.0 ENVIRONMENTAL RADIOLOGICAL MONITORING PROGRAM 3.1 Program Design and Data Interpretation The purpose of the Environmental Radiological Monitoring Program at the Duane Arnold Energy Center (DAEC) 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 nuclear power plants; and (4) Industrial and medical radioactive waste.

In interpreting the data, effects due to the DAEC operation 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 DAEC 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 station 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 radio nuclides present in the environmental samples collected from the DAEC site.

The DAEC's monitoring program includes analyses for strontium-90 and iodine-131, which are fission products, and tritium, which is pro duced by cosmic rays, atmospheric nuclear detonations, and also by nuclear power plants.

Most samples are also analyzed for gamma-emitting isotopes with results for the following groups quantified:

zirconium-95, cesium-137, and cerium-144.

These three gamma-emitting isotopes were 3

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 detona tion.

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 ten (10) days after reactor shutdown.

On the other hand, ten (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).

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 next group, manganese-54, cobalt-58 and -60, and zinc-65, are activation products and arise from activation of corrosion products.

They are typical components of nuclear power plant effluents, but are not produced in significant quantities by nuclear detonations.

Nuclides of the final group, beryllium-7, which is of cosmogenic origin, and potassium-40, a naturally-occuring isotope, were chosen as calibration monitors and should not be considered radio logical impact indicators.

Characteristic properties of isotopes quantified in gamma-spectroscopic analyses are presented in Table 5.1.

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 became operational.

Results of the DAEC'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 radiological monitoring program at the DAEC is summarized in Table 5.2 and is briefly reviewed below.

Table 5.3 defines the sampling location codes used in Table 5.2 and specifies for each location its type (indicator or control) and its distance, direction, and sector relative to the reactor site.

The types of samples collected at each location and the frequency of collections are presented in Table 5.4 using codes defined in Table 5.5.

To monitor the air environment, airborne particulates are collected on membrane filters by continuous pumping at twelve (12) locations.

Also, airborne iodine is collected by continuous pumping through charcoal filters at six (6) of these locations.

Nine (9) of the twelve (12) locations are indicators and three (3) are controls (D-1, D-2, and 4

0-13).

Filters are changed and counted weekly.

Particulate filters are analyzed for gross beta activity.

If gross beta activity exceeds 10 times the yearly mean of the control samples gamma isotopic analysis is performed.

Quarterly composites of airborne particulates from each location are gamma scanned on a germanium detector.

All charcoal filters are analyzed weekly for 1-131 on all samples.

Ambient gamma radiation is monitored at twelve (12) air sampling loca tions.

In addition, gamma radiation is monitored at thirty-two (32) special locations:

seventeen (17) in a circle within 0.5 mi radius of the DAEC stack; six (6) in 22.50 sectors within 1 mi of the DAEC stack; and nine (9) in 22.50 sectors between 1 and 3 miles of the DAEC stack. The sensors are placed in quadruplicate at each location and are exchanged and analyzed quarterly.

Precipitation samples are collected monthly from one location and ana lyzed for gamma-emitting isotopes.

Quarterly composites are analyzed for tritium.

Milk samples are collected monthly from seven (7) locations during the non-grazing season, October through April, and biweekly during the grazing season, May 1 through September 30.

One of the locations is a control (D-105) and the rest are indicators.

All samples are analyzed for 1-131 and gamma-emitting isotopes.

For additional monitoring of the terrestrial environment, grain, hay, and broad leaf natural vegetation samples are collected annually from nine (9) locations:

one control (0-105) and eight (8) indicators (D-57, D-58, D-63, D-72, D-93, D-94, D-106 and D-16).

Grain, hay, and broad leaf (green leafy) vegetation samples are analyzed for gamma-emitting isotopes and at least one broad leaf vegetation is analyzed for iodine-131.

When meat is slaughtered for home

use, it is collected annually during or immediately following a grazing period from animals grazing on site.

The sample is analyzed for gamma-emitting isotopes.

Also, potable ground water is collected quarterly from a treated municipal water system (D-53),

the inlet to the municipal water treatment system (D-54),

and four (4) additional ground water locations (D-55, D-57, D-58, and D-72).

The samples are analyzed for gross beta and tritium. If gross beta activity exceeds 10 times yearly mean of the control samples, gamma isotopic, strontium-89, and strontium-90 analyses are performed.

Soil samples are collected once per year at two indicator locations (D-15 and D-16).

The samples are analyzed for strontium-90 and gamma-emitting isotopes.

Surface water is collected monthly from five (5) river, pond, and sewage effluent locations, one (1) control (D-49) and four (4) indicator (D-50, D-51, 0-99, and D-107).

All monthly samples are analyzed for gamma emitting isotopes.

Tritium analyses are performed on quarterly compo sites from each location.

In addition, all samples from Location D-107 (plant sewage discharge) are analyzed for K-40 by flame photometry.

5

The aquatic environment is also monitored by upstream and downstream (D-49 and D-61) semiannual collections of fish.

River bottom sediment is also collected semiannually at the plant's intake and discharge (D-50 and D-51) and downstream of the sewage plant (D-107).

The 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) No TLD data were available for Locations D-44 and D-39 for the second quarter of 1989 because the TLDs were lost in the field.

(2) No TLD data were available for Location D-10 for the third quarter of 1989 because the TLD was lost in the field.

(3) No TLD data were available for Location D-36 for the fourth quarter of 1989 because the TLD was lost in the field.

(4) No milk samples were collected from Locations D-93 and D-101 on 01-04-89 because samples were not available.

(5) No milk samples were collected from Locations D-93 and D-101 on 02-08-89 because samples were not available.

(6) No milk sample was collected from Location D-101 on 03-07-89 because the sample was not available.

(7) No milk sample was collected from Location D-93 on 05-31-89 because the sample was not available.

(8) Meat samples were not available in 1989 because no meat animals were slaughtered for home use.

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

All gamma-spectroscopic analyses were performed with high resolution germanium detectors.

Levels of iodine-131 in natural vegetation were determined by germanium spectrometry.

Levels of airborne iodine-131 in charcoal samples were measured by germanium spectrometry.

Tritium levels were determined by the liquid scintillation technique.

Analytical Procedures used by TIML are specified in detail elsewhere (Teledyne 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).

Details of TIML's QA Program are presented elsewhere (Teledyne Isotopes Midwest Laboratory, 1989).

The TIML QA Program includes participation in the Interlaboratory Comparison (Crosscheck)

Program.

Results obtained in the crosscheck program are presented in Appendix A.

3.5 Program Modifications There were no program modifications in 1989.

4.0 RESULTS AND DISCUSSION All of the scheduled collections and analyses were made on schedule except those listed in Table 5.6.

All results are summarized in Table 5.7 in a format recommended by the Nuclear Regulatory Commission in Regulatory Guide 4.8.

For each type of analysis of each sample medium, this table lists the mean and range of all indicator and control locations.

The locations with the highest mean and range are also shown.

The tabulated results of all measurements made in 1989 are not included in this section, although references to these results will be made in the discus sion.

The complete tabulation of the 1989 results is contained in Part II of the.1989 Annual Report on the Environmental Radiological Monitoring Program for the Duane Arnold Energy Center.

4.1 Atmospheric Nuclear Detonations and Nuclear Accidents There were no reported atmospheric nuclear tests in 1989.

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 reactor facilities in 1989.

4.2 Program Findings Results obtained show background levels of radioactivity in the environ mental samples collected in 1989.

Airborne Particulates The average annual gross beta concentration in airborne particulates was similar at indicator and control locations (0.026 and 0.029 pCi/m 3,

respectively) and was similar to levels in 1982 (0.026 pCi/m3, at both indicator and control locations),

1983 (0.022 and 0.024 pCi/m 3, respec tively),

1984 (0.025 and 0.026 pCi/m 3, respectively),

1985 (0.024 pCi/

m3 at both locations), in 1986 (0.024 pCi/im3, at both indicator and control locations),

in 1987 (0.024 and 0.026 pCi/m 3, respectively) and in 1988 (0.026 and 0.028 pCi/m 3, respectively).

The average of 0.024 pCi/m 3 for 1986 does not include the results from May 15 to June 12, 1986, which were influenced by the accident at Chernobyl.

8

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 the stratosphere (Gold et al., 1964).

It was pronounced in

1981, occurred to a lesser degree in 1982, and did not occur in 1983,

1984, 1985,

1987, 1988 or 1989.

In 1986, the spring peak could not be identified because it was overshadowed by the releases of radioactivity from Chernobyl.

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.

All other gamma-emitting isotopes were below their respective LLD limits.

No plant effect was indicated.

Airborne Iodine Weekly levels of airborne iodine-131 were below the lower limit of de tection (LLD) of 0.07 pCi/m 3 in all samples.

Ambient Radiation (TLDs)

At twelve (12) air sampling locations, the TLD readings averaged 15.4 mR/quarter at indicator locations and 13.6 mR/quarter at control loca tions.

At locations within 0.5 mile, 1.0 mile, and 3.0 mile radius of the stack, the measurements averaged 18.0 mR/quarter, 19.9 mR/quarter, and 16.5 mR/quarter, respectively.

The 'average for all locations was 17.1 mR/quarter.

This is slightly lower than the estimated average natural background radiation for Middle America, 19.5 mR/quarter, which is based on data on Pages 71 and 108 of the report, "Natural Background Radiation in the United States" (National Council on Radiation Protection and Measurements, 1975).

The terrestrial absorbed dose (uncorrected for structural and body shielding) ranges from 8.8 to 18.8 mrad/quarter and averages 11.5 mrad/quarter for Middle America. Cosmic radiation and cosmogenic radionuclides contribute 8.0 mrad/

quarter for a total average of 19.5 mrad/quarter. No plant effect was indicated.

Precipitation In precipitation, the tritium concentration was below the LLD of 330 pCi/1 in all samples.

All gamma-emitting isotopes were below their respective LLDs. No plant effect was indicated.

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

9

No gamma-emitting isotopes, except naturally occurring potassium-40, were detected in any milk samples.

This is consistent with the finding of the National Center for Radiological Health that most radiocontami nants in feed do not find their way into milk due to the selective metabolism of the cow.

The common exceptions are radioisotopes of po tassium, cesium, strontium, barium, and iodine (National Center for Radiological Health,1968).

In summary, the milk data for 1989 show no radiological effects of the plant operation.

Ground Water The annual mean for gross beta activity measured 3.2 pCi/l and was similar to the levels observed in 1980 through 1988.

The location with the highest mean, 6.8 pCi/l, was D-58, a farm 1.0 miles distant from the plant.

Tritium was below the LLD of 330 pCi/l in all samples.

No plant effect was indicated.

Vegetation Iodine-131 results in broad leaf vegetation were below the LLD level of 0.051 pCi/g wet weight in all samples.

Except for potassium-40, which was observed in all samples (broadleaf vegetation,

corn, hay, and green beans),

all other gamma-emitting iso topes were below detection limits in all samples.

No plant effect was indicated.

Soil Strontium-90 was detected in both samples and averaged 0.046 pCi/g dry weight.

Cesium-137 was detected in both samples and averaged 0.18 pCi/g dry weight.

Both strontium-90 and cesium-137 concentrations were similar to levels observed in 1987 (0.08 and 0.30 pCi/g dry weight, respectively) and in 1988 (0.064 and 0.33 pCi/g dry weight, respectively).

The only other gamma-emitting isotope detected was potassium-40 and averaged 13.1 pCi/g dry weight.

No plant effect on soil was indicated.

Surface Water Tritium was below the LLD level of 330 pCi/l in all samples.

All gamma-emitting isotopes were below their respective LLDs.

10

K-40 was measured at one location, D-107 (plant sewage discharge onsite).

The concentration ranged from 15.6 to 24.0 pCi/1 and averaged 19.3 pCi/l.

No plant effect on the radioactivity of surface water was indicated.

Fish All gamma-emitting isotopes, except naturally-occurring potassium-40, in edible portions were below detection limits.

The potassium-40 level was similar at both indicator and control locations (3.16 and 3.09 pCi/g wet weight, respectively).

No plant effect on fish was indicated.

River Sediments River sediments were collected in May and November,

1989, and analyzed for gamma-emitting isotopes.

Cesium-137 was detected in one sample and measured 0.13 pCi/g dry weight.

Potassium-40 ranged from 6.79 to 11.34 pCi/g dry weight and averaged 8.91 pCi/g dry weight.

All other gamma-emitting isotopes were below detection limits.

There was no indication of plant effect on the environment.

a GB = Gross beta; GS = Gamma scan.

b LLD = Nominal lower limit of detection based on 4.66 sigma error for background sample.

c Mean and range based upon detectable measurements only. Fraction of detectable measurements at specified locations is indicated in parentheses (F).

d Locations are specified by: (1) name and code (Table 5.3); and (2) distance, direction, and sector relative to reactor site.

e Nonroutine results are those which exceed ten times the control station value.

If a control station value is unavailable, the result is considered nonroutine if it exceeds ten times the preoperational value for the location.

f One (1) result has been excluded in the determination of LLD for gross beta.

Higher than normal LLD (<0.01 pCi/m 3) resulted from low volume due to pump malfunction.

9 LLD for airborne iodine could not be reached at two locations during 1989.

Values of <0.289 and <0.279 resulted from extremely low volumes due to air sampler pump malfunctions.

TIML participates in intercomparison studies administered by U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. The results are reported in Appendix A. Also reported are results of in house spikes and blanks. Appendix A is updated twice a year and the complete Appendix is included in January and July monthly reports only.

Please refer to January and July Reports for information.

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 January 1986 through November, 1989.

This program has been conducted by the U.S.

Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Labora tory, 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. Also Teledyne testing results are listed.

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.

Appendix B Data Reporting Conventions B-1

Data Reporting Conventions 1.0.

All activitiesexcept 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 = 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 where L = is the lower limit of detection for a background sample.

3.0. Duplicate Analyses 3.1.

Individual results:

Reported result:

based on 4.66a uncertainty xl +/-s X2 S2 x

s where x = (1/2) (x1 + x2) s=(1/2) S2 + 2 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 xl, x2,.

xn are defined as follows:

1 x

x n

5 (x-x) 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.

SUMMARY

OF THE LAND USE CENSUS D-1

SUMMARY

OF THE 1989 LAND USE CENSUS The 1989 land use census was completed in September. It consisted of a house-by-house inspection out to three (3) miles from DAEC for all sectors except the NW and WNW sectors that were surveyed to five (5) miles from DAEC. The Cedar River water usage was surveyed by contacting the Iowa Department of Natural Resources. No direct observation by boat was performed for the second consecutive year due to extremely low river stages.

The Iowa DNR reported no new water use permits issued for 1989.

The main usage of the Cedar River within three (3) miles downstream of DAEC continues to be recreation and fishing.

The census results indicated less changes in land use due to the drought in 1989, than were observed in 1988.

More gardens were observed, as soil moisture improved slightly. A continuation of the home building trend in the SE sector was observed.

No changes in the environmental sampling locations were recommended, as changes in land use did not present any new station-receptor relationships that are not already monitored.

Additionally, a review of the dose calculations included in Appendix E of this report shows that the maximally exposed receptors are in sectors with appropriate sampling.

In all cases, the calculated doses were insignificant.

D-2

APPENDIX E ANNUAL RADIATION DOSE ASSESSMENT E-1

ANNUAL RADIATION DOSE ASSESSMENT The annual offsite radiation dose to a member of the public was determined using environmental dosimeters and by calculations based on monitored effluent releases.

Section A.

Dose Contribution from Direct Radiation Direct radiation dose from the operation of DAEC was recorded by TLDs placed at locations in the surrounding environment as described in the Offsite Dose Assessment Manual (ODAM).

Observations from the collected data follow:

1.

Pre-operational and 1989 TLD results were compared using a paired difference test. No difference in the populations were observed at 0.5 and 1 mile using a confidence level of 99%.

2.

As stated earlier in this report (part 1, page 9) no plant effect was indicated by the TLDs, as dose results were less than the estimated average natural background for Middle America.

Section B.

Calculated Dose from Effluent Releases The contribution of dose to a member of the public most likely to be exposed from effluent releases was calculated by the Meteorological Information and Dose Assessment System (MIDAS) computer program in accordance with the ODAM. The calculation methods follow those prescribed by Reg Guide 1.109.

Results of these calculations are discussed below:

1.

There were no liquid releases in 1989.

2.

The doses to air from noble gas released were 1.09E-2 mrad from gamma radiation and 1.25E-2 mrad from beta radiation, both at the south site boundary.

3.

The total body dose equivalent to the maximally exposed individual from noble gases was 7.71E-4 mrem, at 1561 meters NNW.

4.

The skin dose equivalent to the maximally exposed individual from noble gases was 2.02E-3 mrem, at 1561 meters NNW.

5.

The dose equivalent to the maximally exposed individual from iodines and particulates with half-lives greater than eight days was 1.31E-2 mrem to the thyroid of a child at 1561 meters NNW.

E-2

Conclusion No measurable dose was detected by environmental TLDs in 1989.

The calculated dose to the maximally exposed individual for 1989 was 1.39E-2 mrem, and represents the contributions to the total body from noble gases and to a child's thyroid from particulates and iodines. The calculated doses are well below the regulatory limits stated in Appendix I to 10CFR50 and in 40CFR190.
