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 1993. 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 11 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. The Duane Arnold Energy Center 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 j

1975.

3.0 ENVIRONMENTAL RADIOLOGICAL MONITORING PROGRAM 3.1 Procram Desien and Data Intercretation 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 (TLDs).

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 controllocation. 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 technic ue involves analyses for specific radionuclides present in the environmental samples co.lected 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 produced 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 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 i

detonation. Each of the three isotopes is produced in roughly equivalent amounts by a l

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.

. 'l 3.1 Procram Desien and Data Interoretation (continued)

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

Characteristic properties of isotopes quantified in gamma-spectroscopic analysis 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 Procram Descriotion The sampling and analysis schedule for the environmental n c'iological 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 i

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 D-13).

i Filters are changed and counted weekly. Particulate filters are analyzed for gress 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.

Charcoal filters are analyzed weekly for I-131 on all samples.

Ambient gamma radiation is monitored at twelve (12) air sampling locations. In addition, gamma radiation is monitored at thirty-two (32) special locations: seventeen j

(17) in a circle within 0.5 mi. radius of the DAEC stack; six (6) in 22.5' sectors within 1 i

mi. of the DAEC stack; and nine (9) in 22.5' sectors between 1 and 3 miles of the DAEC stack. Two TLDs are placed at each location and are exchanged and analyzed quarterly.

Precipitation samples are collected monthly from one location and analyzed 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 location is a control (D-105) and the rest are indicators. All samples are analyzed for I-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 (D-105) and eight (8) indicators (D-57, D-58, D-63, D-72, D-93, D-94, D-106 and 4

3.2 Procram Description (continued)

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 cattle are 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).

i 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, D-99, and D-107).

All monthly samples are analyzed for gamma-emitting isotopes. Tritium analyses are performed on quarterly composites from each location. In addition, all samples from Location D-107 (plant sewage discharge) are analyzed for K-40 by flame photometry.

The aquatic environment is qlso 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.

i 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 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 gamma spectrometry. Levels of airborne iodine-131 in charcoal samples were measured by 4

gamma spectrometry.

j Tritium levels were determined by the liquid scintillation technique.

Analytical Procedures used by TIML are specified in detail elsewhere (Teledyne Isotopes Midwest Laboratory,1993). Procedures are based on those prescribed by the National l

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).

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 1993 are not included in this section, although references to these results will be made in the discussion. The complete tabulation of the 1993 results is contained in Part II of the 1993 Annual Report on the Environmental Radiological Monitoring Program for the Duane Arnold Energy Center.

4.1 Atmosoheric Nuclear Detonations and Nuclear Accidents There were no reported atmospheric nuclear tests in 1993. 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 1993.

4.2 Procram Findines Results obtained show background levels of radioactivity in the environmental samples collected in 1993.

Airborne Particulates The average annual gross beta concentration in airborne particulates was similar at 3

indicator and control locations (0.022 and 0.023 pCi/m, respectively) and was similar 1982 (0.026 pCi/m, at both indicator and control locations), 1983 (0.022 3

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

pCi/m, respectively), in 1989 (0.026 and 0.029 pCi/m, respectively), in 1990 (0.022 3

3 and 0.024 pCi/m, respectively), in.1991 (0.023 and 0.022 pCi/m, respectively), and 3

in 1992 (0.022 and 0.023 pCi/m3, respectively). The average of 0.024 pCi/m for 1986 does not include the results from May 15 to June 12,1986, which were influenced by the accident at Chernobyl.

A spring peak in beta activity had been observed almost annually for many years (Wilson d d.,1969). It had been attributed to fallout of nuclides from the stratosphere (Gold d M.,1964). It was pronounced in 1981, occurred to a lesser degree in 1982, and did not occur in 1983,1984,1985,1987,1988,1989,1990,1991,1992, or 1993. In 1986, the spring peak could not be identified because it was overshadowed by the releases of radioactivity from Chernobyl. Gamma spectroscopic analysis of c uarterly composites of air paniculate filters yielded similar results for indicator anc control locations. Beryllium-7, which is produced continuously in the upper atmosphere by 7

Airborne Particulates (continued) 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 k> dine Weekly levels of airborne iodine-131 were below the lower limit of detection (LLD) of 3

0.07 pCi/m in all samples.

)

Ambient Radiation (TLDs)

At twelve (12) air sam aling locations, the TLD readings averaged 14.4 mR/ quarter at indicator locations anc 13.8 mR/ quarter at control locations. At locations within 0.5 mile,1.0 mile, and 3.0 mile radius of the stack, the measurements averaged 16.8 i

uarter, and 16.2 mR/ quarter, respectively. The average for all mR/ quarter,17.6 mR/q/ quarter. This is slightly lower than the estimated avera locations was 16.1 mR 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 1

radiation and cosmogenic radionuclides contribute 8.0 mrad / quarter for a total average of 19.5 mrad / quarter. No plant effect was indicated.

Precioitation In precipitation, the tritium concentration was below the LLD of 330 pCi/L in all samples. No gamma-emitting isotopes were detected. No plant effect was indicated.

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

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 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 i

Health,1968).

l In summary, the milk data for 1993 show no radiological effects of the plant operation.

Ground Water The annual mean for gross beta activity measured 3.5 pCi/L and was similar to the levels observed in 1980 through 1992. The location with the highest mean (7.0 pCi/L) was D-58, a farm 1.0 mile distant from the plant. Tritium was below the LLD of 330 pCi/L in all samples. No plant effect was indicated.

Vecetation Iodine-131 results in broad leaf vegetation were below the LLD level of 0.060 pCi/g wet weight in all but one sample. The LLD could not be reached for location D-105, due to the small sample size.

Cs-137 was detected in one vegetable sample at a concentration of 0.036 pCi/g wet.

Except for potassium-40, which was observed in all vegetation samples ( broadleaf, grain, and forage ), all ather gamma-emitting isotopes were below detection limits in all samples. No pla.i offect is indicated.

Soil Strontium-90 was detected in both samples and averaged 0.058 pCi/g dry weight.

Cesium-137 was detected in both samples at a concentration of 0.26 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), in 1988 (0.064 and 0.33 pCi/g dry weight, respectively), in 1989 (0.046 and 0.18 pCi/g dry weight, respectively), in 1990 (0.066 and 0.21 pCi/g dry weight, respectively), in 1991 (0.064 and 0.34 pCi/g dry weight, respectively), and in 1992 (0.040 and 0.26 pCi/g dry weight, respectively).

The only other gamma-emitting isotope detected was potassium-40 and averaged 13.68 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.

K-40 was measured at one location, D-107 (sewage effluent). The concentration ranged from 9.1 to 19.9 pCi/L and averaged 15.4 pCi/L..

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

Eish 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 (2.80 and 2.68 pCi/g wet weight, respectively). No plant effect on fish was indicated.

River Sediments River sediments were collected in September and October,1993, and analyzed for gamma-emitting isotopes. Cobalt-60 was detected in one sample from location D-107 (sewage effluent) at a concentration of 0.035 pCi/g dry weight. Cesium-137 was detected at both indicator and control locations at an average concentration of 0.027 pCi/g dry weight. Potassium-40 ranged from 7.16 to 9.91 pCi/g dry weight and averaged 8.54 pCi/g dry weight.

All other gamma-emitting isotopes were below detection limits. There was no indication of a plant effect on the environment.

a Gamma isotopic analysis end analysis for gamma-emitting nuclides refer to high resolution gamma ray spectrum analysis. Any radionuclide detected at a concentration greater than the lower limit of detection (LLD) should be reported quantitatively; conversely, any radionulcide concentration less than the LLD should not be reported.

b Tlw grazing season is considered to be May 1 through September 30.

  • GB = gross beta; GS = gamma scan.

b LLD = Nominallower lumt of detection based on 4 66 sigma countmg error for the background sample.

Mean and range based upon detectable measurements only. Fraction of detectable measurements at specified locations is C

indicated in parenthews (F).

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

8 Non routine results are those which exceed ten times the control station value for the location. If a control station value is not available, the result is considered non-routme if it exceeds ten times the preoperational value for the location.

3 I Three locations (D-1, D-2, D-3) had identical means of 0.023 pCi/m Only D-1 is detailed in this summary table.

8 One sample could not reach the required LLD due to small sample size (40 grams).

NOTE: Tehdyne's Midwest Laboratory 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 four times a year, the complete Appendix is included in March, June, September and December monthly progress reports only. Please refer to March, June, September and December progress reports for information.

Appendix A Interlaboratorv Comoarison Program Results Teledyne's 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 conctntrations 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 agen'cy. 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 and air filters during the period 1990-1993.

This program is 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 (TLDs), since 1976 via various Intemational Intercomparisons 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 for the past twelve months.

Data for previous years are 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 are available upon request.

Attachment A lists acceptance criteria for " spiked *' samples.

Out-of-limit results are explained directly below the result.

Gross Alpha analysis was repeated with similar results. An investigation of possible causes for the deviation from the EPA was conducted with no cause discovered. The sample was spiked with Th-230; so Alpha Spec Analysis for Th-230 was performed in triplicate with results of 15.5i2.1,13.411.4, and 14.812.0. It should be noted that 66% of all participants failed this analysis with a grand average of 17.1. This coupled with the support of the Alpha Spec results leaves TIML cause to believe that there may have been 'a dilution error at the EPA. It should be noted that on the next Gross Alpha EPA check, TIML reported results that where exactly the known value. Since ne apparent cause can be found, and TIML had outstanding results on the I

following sample, it is felt that no further investigation is needed.

l 2.0 Sincie Meas.urements l

Each single measurement is reported as follows:

L xts 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 I

<L

)

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

3.0 Duplicate analyses l

3.1 Individual results:

Comoutation of Averaces 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) are defined as follow:,

of a set of n numbers x1, x2

.xn 1

i = - E, x

E(R - x,)2 s=

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.

i 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 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 five 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 1993 LAND USE CENSUS The annual Land Use Census for DAEC was completed on August 6, 1993.

All milk animals and gardens greater than 500 square feet were identified within three miles for each of 16 sectors.

Within five miles, the nearest resident, milk animal and garden in each sector were identified.

Additionally, on September 25, 1993 the Cedar River was inspected for water use downstream of DAEC to Cedar Rapids.

There were no new uses of water.

Gardening activity was subdued this year due to heavy rains in the spring and summer.

A total of 15 new homes were built or under construction since the last census.

Most of the new homes were built in the sectors toward Cedar Rapids (SSE, SE and ESE) where increased building rates have been noted in previous land use census.

Three new homes were noted in the town of Palo (S and SSW) and four were noted near Pleasant Creek (WNW).

No changes in the DAEC Radiological Environmental Monitoring Program are recommended based on the Land Use Census.

ANNUAL RADIATION DOSE ASSESSMENT The annual offsite radiation dose to a member of the public was determined by assessment of environmental dosimeter results 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) 1.

Pre-operational and 1993 TLD results were compared using a paired difference test.

No difference in the TLD populations were observed at 0.5 and 1 mile using a confidence level of 99%.

2.

As stated in Part 1, page 8 of this report, no plant effect was indicated by the TLDs when dose results were compared to the estimated average natural background for Middle America.

SECTION B.

ESTIMATED OFFSITE DOSE FROM EFFLUENT RELEASES The contribution of dose to a member of the public most likely to be exposed f_om effluent releases was calculated by the Meteorological Information and Dose Assessment Systems (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 and shown in tabular form on Page E-4:

1.

There were no releases of radioactive material to liquid effluents in 1993.

2.

The dose to air from noble gases released was 5.25E-3 mrad from gamma radiation at the West site boundary and 6.73E-3 mrad from beta radiation at the West site boundary.

3.

The total body dose equivalent to the maximally exposed individual from noble gases was 2.70E-3 mrem, at 805 meters t

West.

4.

The skin dose equivalent to the maximally exposed individual from noble gases was 6.73E-3 mrem, at 805 meters West.

5.

The maximally exposed organ due to iodines and particulates with half-lives greater than eight days was the skin of a child at 805 meters West, with an estimated dose equivalent of 1.08E-2 mrem.

E-2

CONCLUSION:

No measurable dose due to operation of DAEC Eas detecteck by environmental TLDs in 1993.

The calculated doses are below the regulatory limits stated in Appendix I to 10 CFR 50 and in 40 CFR l

190.
