3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 3.1 Program Design and Data Interpretation The purpose of the Radiological Environmental Monitoring Program at the Duane j 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 j radionuclides;

{

1 (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 l for by typical fluctuations in radiation levels arising from other sources.

An additional interpretive technic ue involves analyses for specific radionuclides present l

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 t

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 l 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 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.

3.1 Program Design 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 o perational. 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 locations. Also, airborne iodine is collected by continuous pumping through charcoal filters at six of these locations. Nine of the twelve locations are indicators and three are controls (D-1, D-2, and D-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.

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

Ambient gamma radiation is monitored at twelve air sampling locations. In addition, gamma radiation is monitored at thirty-three special locations: seventeen in a circle within 0.5 mi. radius of the DAEC stack; six in 22.5 sectors within 1 mi. of the DAEC stack; and ten 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, j l

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 five locations during the non-grazing season, l October through April, and biweekly during the grazing season, May 1 through l 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 vegetation samples are collected annually, as available, from nine locations: one control ,

(D-105) and eight indicators (D-16, D-57, D-58, D-63, D-72, D-93, D-94, and D-106).  !

Grain, hay and broad leaf (green leafy) vegetation samples are analyzed for gamma-4

Program Description (continued) emitting isotopes and at least one broad leaf vegetation is analyzed for iodine-131. If cattle are slaughtered for home use, a meat sample 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 additional ground water locations (D-55, D-57, D-58, l and D-72). The samples are analyzed for gross beta and tritium. If gross beta activity exceeds 10 times the yearly mean of the control samples, gamma isotopic, strontium-89 l and strontium-90 analyses are performed.

t l 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 river, pond and sewage effluent locations, one control (D-49) and four 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 also monitored by upstream and downstream (D-49 and D-

61) semiannual collections of fish. River bottom sediment is also collected semiannually l at the plant's intake and discharge (D-50 and D-51) and downstream of the sewage l plant (D-107). The samples are analyzed for gamma-emitting isotopes.

3.3 Procram Execution I l

l The program was executed as described in the preceding section with the following exceptions:

(1) No air particulate sample was available from location D-13 for the week ending January 23,1997. The sample was lost in the field due to strong winds.

! (2) TLD data was not available for the third quarter,1997 from locations D-31 and D-91. The TLDs were lost in the field.

(3) TLD data was not available for the fourth quarter,1997 from location D-35. The i TLD was lost in the field. l (4) No milk was available from location D-93 and D-101 for January and February,

1997. The goats v'ere dry.

(5) No milk was available from location D-105 for the week ending June 17,1997.

i 5

3.4 ' Laboratory Procedures All iodine-131 analyses in milk 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-spectrosco:>ic analyses were performed with high resolution germanium detectors. Levels of loc ine-131 in vegetation were determined by gamma spectrometry.

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

Tritium levels were determined by the liquid scintillation technique.

Analytical Procedures used by TBEESML 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).

Details of TBEESML's QA program are presented elsewhere (Teledyne Isotopes Midwest Laboratory,1992 ). The TBEESML 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 during the year,1997, i

6  ;

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 1997 are not included in this section, although references to these results will be made in the discussion. The complete tabulation of the 1997 results is contained in Part II of the 1997 Annual Report on the Radiological Environmental Monitoring Program for the Duane Arnold Energy Center.

4.1 Atmospheric Nuclear Detonations and Nuclear Accidents There were no reported atmospheric nuclear tests in 1997. 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 1997.

4.2 Program Findings Results obtained show background levels of radioactivity in the environmental samples collected in 1997. l Airborne Particulates The average annual gross beta concentration in airborne particulates was similar at indicator and control locations (0.023 and 0.024 pCi/m3, respectively) and similar to levels in 1984 (0.025 and 0.026 pCi/m3 , respectively), 1985 (0.024 pCi/m3 at both locations), in 1986 (0.024 pCi/m3, at both indicator and control locations), in 1987 (0.024 and 0.026 pCi/m3, respectively), in 1988 (0.026 and 0.028 pCi/m3 ,

respectively), in 1989 (0.026 and 0.029 pCi/m3, respectively), in 1990 (0.022 and 0.024 pCi/m3, respectively), in 1991 (0.023 and 0.022 pCi/m 3, respectively), in 1992 (0.022 and 0.023 pCi/m 3, respectively), in 1993 (0.022 and 0.023 pCi/m3, respectively), in 3 3 1994 (0.023 and 0.024 pCi/m , respectively),3in 1995 (0.025 and 0.024 pCi/m ,

respectively) and in 1996 (0.024 and 0.023 pCi/m , respectively). The average of 0.024 pCi/m3 orf 1986 does not include the results from May 15 to June 12,1986, which were influenced by the accident at Chernobyl.

A s 3 ring peak in beta activity had been observed almost annually for many years (Wi. son d al.,1969). It had been attributed to fallout of nuclides from the stratosphere (Gold d al.,1964). It was pronounced in 1981, occurred to a lesser degree in 1982, and did not occur from 1983 through 1997, 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 7

Airborne Particulates (continued) in all samples. All other gamma-emitting isotopes were below their respective LLD limits. No plant effect was indicated.

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

Ambient Radiation (TLDs)

At twelve air sampling locations, the TLD readings averaged 13.3 and 12.7 mR/ quarter for indicator and control locations, respectively. At locations within 0.5 mile,1.0 mile, and 3.0 mile radius of the stack, the measurements averaged 14.8 mR/ quarter,15.5 mR/ quarter, and 12.8 mR/ quarter, respectively. The average for all locations was 14.0 mR/ quarter. This is lower than the estimated average natural backgrou: .1 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, j

)

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 Ca 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 Health,1968).

In summary, the milk data for 1997 show no radiologica! 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 1996. The location with the highest mean (5.0 pui/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.

S

l Vegetation Iodine-131 results in broadleaf vegetation were below the LLD level of 0.053 pCi/g wet weight in all samples.

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

Soil Strontium-90 was detected in both samples and averaged 0.051 pCi/g dry weight.

Cesium-137 was detected at an average concentration of 0.20 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), in 1992 (0.040 and 0.26 pCi/g dry weight, respectively), in 1993 (0.058 and 0.26 pCi/g dry weight, respectively), in 1994 (0.040 and 0.27 pCi/g dry weight, respectively),in 1995 (0.044 and 0.21 pCi/g dry weight, respectively) and in 1996 (0.050 and 0.17 pCi/g dry weight, respectively).

The only other gamma-emitting isotope detected was potassium-40 at an average concentration of 12.94 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 9.5 to 23.4 pCi/L and averaged 16.4 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 de+cction limits. The potassium-40 level was similar at both indicator and control locations (2.88 and 2.80 pCi/g wet weight, respectively). No plant effect on fish was indicated.

River Sediments River sediments were collected in June and September,1997, and analyzed for gamma-emitting isotopes. Traces of Cobalt-60 were detected in two samples from location D-107 (sewage effluent) at an average concentration of 0.20 pCi/g dry weight. Potassium-40 ranged from 5.15 to 10.99 pCi/g dry weight and averaged 7.25 pCi/g dry weight.

All other gamma-emitting isotopes were below detection limits.

Interlaboratory Comparison Procram Results i l

\ l Teledyne Brown Engineering Environmental Services Midwest Laboratory (formerly Hazleton i l 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 1 l provide an independent check on the laboratory's analytical procedures and to alert it to any po>sible l problems.

Participant laboratories measure the concentration of .pecified 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 and air filters during the past twelve months. Data for previous years is available upon request.

This program is conducted by the U.S. Environmental Protection Agency Office of Research and Developement National Exposure Research Laboratory Characterization Research Division-Las Vegas, ,

l Nevada. i i 1 The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various l International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2.

l Also Teledyne testing results are listed.

Table A-3 lists results of the analyses on in-house " spiked" samples for the past twelve months. All j samples are prepared using NIST traceable sources. 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.

i l Table A-5 list 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.

Attachment A lists acceptance criteria for " spiked" samples.

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

APPENDIX B DATA REPORTING CONVENTIONS B-1

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

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

x s where x = value of the measurement; s = 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 where L = the lower limit of detection based on 4.660 uncertainty for a background sample.

3.0. Duplicate analyses 3.1 Individual results: x1 is1 x2 i s2 Reoorted result: xis where x = (1/2)(x3 + x2) s = (1/2) k sf + s!

3.2. Individual results: <Li

<L2 Reoorted result: <L where L = lower of L 3and L2 3.3. Individual results: xis

<L Reoorted result: x i s if x 2 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 x and standard deviation s of a set of n numbers x3, x2 xnare defined as follows:

x=fEx s= I(x- x)2 n-1 L

l 42 Values below the highest lower limit of detection are not included m 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:

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 equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example,11.445 is rounded off to 11.45.

SUMMARY

OF THE LAND USE CENSUS 1

l 1

I .

i D-1

L Appendix D SummaIV of the Land Use Census The Duane Arnold Energy Land Use Census for 1997 was completed during the third week of September 1997. All milk animals and gardens greater than 500 square feet were identified within three miles for each of the 16 meteorological sectors. If none were identified within the three mile range, additional surveys were performed out to a distance of five miles. The Cedar River was suneyed by boat on July iIth 1997 for water use downstream of the DAEC to Cedar Rapids.

l There were 147 gardens found in the 1997 Census. This number exceeds the number of gardens found in the 1996 survey by 10. This difference can be attributed to the removal of 47 gardens and the addition of 57 new gardens.

Milk animals locations remained unchanged since the 1995 census. Two of the locations j have goats that do not provide samples during the winter months.

l The locations of the nearest resident for each sector remained the same. Twenty-two new homes were built or were under construction within three miles of the DAEC, compared to the thirty new homes identified in 1996. Most of the new houses built were located in the sectors between the plant and Cedar Rapids (SSE, and SE) and in Palo (S and SSW).

A listing of the newly identified homes is attached.

The Cedar River survey revealed no new withdrawals of river water compared to previous j surveys. Irrigation of the strawberry farm in Palo and fishing remain the only food i pathway uses of river water between the DAEC and Cedar Rapids.

l Several adjustments were made to the MIDAS dose projection model based on the results of this census. They include changes to the location of the nearest gardens for the NNE, ENE, ESE, SE, SSW, SW and WNW sectors.

ANNUAI. RADIATION DOSE ASSESSMENT l

I t

E1 i i l

Appendix E 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 the DAEC was reported by TLDs placed at locations in the surrounding environment as described in the Offsite Dose Assessment Manual (ODAM).

1. Pre-operational and 1997 TLD results were compared using a paired difference test.

No significant differences in the TLD populations were observed for the 0.5 mile and one mile TLD populations using a confidence level of 99%.

2. As stated in Part 1, page 8 of this repon, 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 EfHuent 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 ODAM. The calculation methods follow those prescribed by Reg Guide 1.109. Because there were no nuclides detected in the environment at or beyond the site boundry that were due to the operation of the DAEC, no comparison of calculsted dose from stack releases and dose calculated from environmental contamination was performed.

Results of the MIDAS dose calculations are discussed below and are shown in tabular form on page E-4

1. There were no releases of radioactive material to liquid effluents in 1997, i
2. The dose to air from noble gases released was 2.76E-03 mrad from gamma radiation at 455 meters South and 2.87E-04 mrad beta radiation at 4022 meters WNW. .

)

3. The total body dose equivalent to the maximally exposed individual from noble gases was 1.78E-03 mrem, at 805 meters West.

E-2

4. The skin dose equivalent to the maximally exposed individual from noble gases was 1.82E-03 mrem, at 805 meters West.
5. The maximally exposed organ due to iodines and particulates with half-lives greater than eight days was the thyroid of a child at 805 meters West, with and estimated dose equivalent of 5.62E-03 mrem.

==

Conclusion:==

No measureable dose due to the operation of the DAEC was detected by environmental TLDs in 1997. The calculated doses are below the regulatory limits stated in Appendix I to 10 CFR 50 and in 40 CFR 190.
