1. 0 INTRODUCTION The preoperational radiological environmental monitoring program for Fermi-2 was initiated on March 15, 1978. Fermi-2 attained initial criticality in June, 1985 and operated at less than five percent power for testing until shutdown during October,1985; the plant remained inoperative for the balance l

of the year. This Annual Report of Fermi-2's radiological environmental monitoring program summarizes the results of measurements and analyses ofi data obtained by Teledyne Isotopes for samples collected during 1985.

Fermi-2 is a boiling water reactor (BWR) designed to operate at a power level of about 1150 megawatts of electrical output with the main condenser circu-1ating water cooled by two natural-draf t, wet-type hyperbolic cooling towers.

The plant is located on approximately 1120 acres about 8 miles east-northeast a of Monroe, Michigan; 30 miles southwest of downtown Detroit, Michigan; and 25 miles northeast of downtown Toledo, Ohio. Fermi-2, bounded on the east by Lake Erie, is situated in Frenchtown Township in Monroe County, Michigan.

3. 0 RADIOLOGICAL ENVIRONMENTAL MONITORIriG PROGRAM 3.1 Program Design and Interpretation United States Nuclear Regulatory Commission (NRC) regulations (10 CFR 50.34) require that nuclear power plants be designed, constructed, and operated to keep levels of radioactive material in effluents to f.

~

unrestricted areas as low as reasonably achievable (ALARA). To ensure '

that these criteria are met, each license authorizing reactor operation includes technical specifications (10 CFR 50.36a) governing the release of radioactive effluents.

In-plant monitoring is used to ensure that these predetermined release limits are not exceeded. However, as a precaution against unexpected and undefined processes that might allow undue accumulation of radioactivity in any sector of man's environment, a program for monitoring the plant environs is also conducted.

The regulations governing the quantities of radioactivity in reactor effluents allow nuclear power plants to contribute, at most, only a few percent increase above normal background radioactivity. Background levels at any one location are not constant but vary with time as they are influenced by such external events as cosmic ray bombardment, weapons test fallout, and seasonal variations. These levels also can vary spatially within relatively short distances reflecting variation in geological composition. Because of these spatial and temporal varia-tions, the radiological surveys of the plant environs are divided into

,i preoperational and operational phases. The preoperational phase of the program of sa@ ling and measuring radioactivity in various media permits a general characterization of the radition levels and concentrations prevailing prior to plant operation, along with an indication of the degree of natural variation to be expected. The operational phase of the program obtains data that, when considered along with the data obtained in the preoprational phase, assist in the evaluation of the radiological impact of plant operation.

I@lementation of the preoperational monitoring program fulfilled the following objectives:

l

Evaluation of procedures, equipment, and techniques, i

Identification of potentially important pathways to l be monitoreo af ter tne plant is in operation. !

i 3

f

- Measurement of background levels and their variations along potentially important pathways in the area surrounding the plant.

Provision of baseline data for statistical comparison with future operational analytical results.

1 Sampling locations were selected on the basis of local ecology, meteor-I ology, physical characteristics of the region, and demographic and land-use features of the site vicinity. The preoperational program was l originally designed on the basis of the NRC Branch Technical Position on radiological environmental monitoring issued by the Radiological Assessment Branch (March 1978). When this position document was revised ..

in November, 1979, the Fermi-2 environmental monitoring program was i modified accordingly. ,

Each year a " Land Use Census" is conducted to determine what changes, if any, have occurred in the locations of the milk animals, gardens, and residences within five (5) miles of Fermi-2. The results of this census are analyzed to ensure that the sampling locations remain representative and that dose projections continue to be conservative. The results of the 1985 Land Use Census are included in this report as Appendix C.

In 1985, the radiological monitoring program included the measurement of ambient gamma radiation by thermoluminescent dosimetry; the determination of gamma-emitters in drinking and surface water, fodder, food products, shoreline sediments, and fish; the determination of gross beta and gamma-emitters in air particulates; the measurement of airborne I-131 in charcoal cartridges; the measurement of gross beta in drinking water; the determination of gamma-emitters and I-131 in milk and grass; and the measurement of tritium in drinking and surf ace water.

3. 2 Program Description "

Fif ty-seven (57) locations within a radius of about 20 miles of the

) Fermi-2 site were monitored. The number and location of monitoring points were determined by considering the locations where the hignest of f -si te environmental concentrations were predicted utilizing plant effluent source terms, site hydrology, and site meteorological condi-

! tions. Other factors considered were applicable regulations, population distribution, ease of access to sagling stations, security, and future

, program integrity.

The environmental radiological monitoring program for Fermi-2 is suma-rized in Table 5.0-1. Table 5.0-2 describes sample locations, associated i media, and approximate distance and direction from the site. Figures 1 through 3 designate sampling locations by station number.

3.2.1 Airborne Particulates and Iodine-131 To monitor the air environment, airborne particulates are collected on glass fiber filters by continuous pumping at a volumetric rate of approximately one cubic foo per minute at five locations.

Also, airborne iodine is collected by continuous pumping through charcoal filters at all of these locations. Four of the five locations are indicators (F-1, F-4, F-5, F-17), and one is a control (F-7). Filters are exchanged weekly and analyzed for gross beta activity. Quarterly composites from each location are analyzed for gamma-emitting iosotopes. Data are presented in Section 7.0, Tables 3 through 9. Additionally, monthly averages ,

3 of gross beta concentrations are graphed and presented in Section J 7.0, Figures 1 through 5.

1 3.2.2 kbient Gamma Radiation - TLD Mblent gamma radiation is measured at thirty-eight (38) locations with CaSO4:Dy dosimeters (Teledyne). Thirty-four (34) loca-tions are indicators (F-1 through F-6, S-1 through S-20, S-23, and S-25 through S-30), and four (4) are controls (F-7, S-21, S-22 and S-24).

Two cards, "A" and "B," each with four readout areas, are placed at each location. They are exchanged and read quarterly. Data are presented in two separate formats, one by location and the other by meteorological sector in Section 7.0, Tables 1 and 2. -

3.2.3 Surface Water Monthly composite samples are collected from two (2) locations, -

F-12 (indicator) and F-14 (control). The samles are analyzed monthly for gamma-emitting isotopes, and then composited quarterly l and analyzed for tritium. Data are presented in Section 7. 0, Tables 10 and 12.

3.2.4 Drinking Water Monthly composite samples are collected from two (2) locations, F-13 (indicator) and F-15 (control). The sagles are analyzed-monthly for gross beta and gamma-emitting isotopes, and then composited quarterly and analyzed for tritium. Data are presented in Section 7.0, Tables 11 and 12.

O 3.2.5 Milk Milk samples are collected semimonthly, June 15 through October 15, and monthly October 15 through June 15, from five (5) loca-tions, four (4) indicator (F-19, F-I, F-31, and F-32) and one (1) control (F-7). The samples are analyzed for iodine-131 and gamma-emitting isotopes. Data are presented in Section 7.0, Table 14.

3.2.6 Grass Grass samples are collected semimonthly June 15 through October 15 and monthly October 15 through June 15 in lieu of milk from one (1) indicator location, F-18. Grass samples are to be collected from any milk location when the milk sample is unavailable to the collector. The samples are analyzed for iodine-131 and gama-emitting isotopes. Data are presented in Section 7.0, Table 15, 3.2.7 Food Crops Vegetables are collected twice during the growing season at four locations, two (2) indicator (Masserant Farm and Roland Farm) and two (2) control (Dennison Farm and Happy Farm). Samples are analyzed for gamma-emitting isotopes. Green leafy vegetables are analyzed for iodine-131 in addition to gamma-emitting isotopes.

Data are presented in Section 7.0, Table 17, 3.2.8 Fish Fish art collected semiannually from two (2) locations, one indicato.- (F-16) and one control (F-1). The edible flesh is separated from the bone and is analyzed for gamma-emitting iso-topes. Data are presented in Section 7.0, Table 18.

3.2.9 Bottom Sediments Sediment samples are collected semiannually from four (4) loca-tions. Three (3) of f-site (F-8, F-9, and F-10) and one (1) on-site (F-22). The samples are analyzed for gamma-emitting isotopes. Data are presented in Section 7.0, Table 13.

.s 3.2.10 Fodder Fodder is collected annually when milk animals are on stored feed from five (5) -locations, four (4) indicator (F-19, F-20, F-31, and F-32), and one (1) control (F-7). The samples are analyzed for gamma-emitting isotopes. Data are presented in Section 7.0, Table 16.

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

1. No grass was available for analysis from Location F-18 J for the collection dates of 01-13-85, 02-11-85, 03-09-85, and 12-15-85. Grass from this location was tenporarily unavailable due to snow cover.

2. No milk was available for analysis from Loction F-32 for the collection date of 03-09-85. Milk was un-

' available because the cow was dry.

3. No TLD data were available, from Locations F-3, S-10, ,

S-14, and 5-28 for the second quarter, or from Loca- -

tions S-17 and S-30 for the third quarter, 1985 1 because the TLDs were lost in the field.

4. No air particulate or air iodine data was available for analysis from Location F-4 for the collection period ending 06-24-85. The samples were unavailable due to a pump malfunction.

i

5. No ' grass was available for analysis from Location F-18

for the month of August. The sample was inadvertently missed by the collector.

6. No fodder was available for analysis from location l

F-19 for the collection date of 12-29-85. The sanple was inadvertently missed by the collector.

3. 4 Analytical Procedures Analytical procedures used by Teledyne Isotopes Midwest Laboratory are

, described in detail elsewhere (Teledyne Isotopes Midwest Laboratory, 1985). Procedures are based on those prescribed by the National Center of 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 collections and analyses were made as scheduled except as listed in the Listing of Missed Samples, Section 7.0 (as well as Page 7, Section 3.3).

All results are summariied in Table ~ 5.0-4 in a format recommended by the Nuclear Regulatory Commission in Regulatory Gu i de 4. 8. For each type of ',

analysis of each sampled medium, this table lists the mean and range for all indicator locations and for all control locations. The locations with the highest mean and range are also shown.

4.1 Atmospheric Nuclear Detonations There were no reported atmospheric nuclear tests in 1985. The last reported test was conducted by the People's Republic of China on 16 October 1980. The reported yield was in the 200 kiloton to 1 megaton range.

4. 2 Program Findings Program findings show background levels of radioactivity in the environ-mental sanples collected in the vicinity of the Fermi-2 Atomic Power Plant. No plant effect on the environment was indicated.

Airborne Particulates and Iodine-131 The annual gross beta concentration in airborne particulates averaged 0.022 pCi/mJ at both indicator and control locations. The highest annual mean concentration was for location F-17 (0.023 pCi/m3),

Food Crops Gama-emitters in food crops, except potassium-40, were below their respective LLDs in all samples. Iodine-131 was belcw tha !.LD level of 60 pCi/kg wet weight in all leafy samples analyzed. No station effect was indicated.

Fish In fish, all gama-emitters, except for potassium-40, .were below their respective LLDs. Cs-137 concentrations averaged 20.0 pCi/kg wet weight and 56.6 pCi/kg wet weight at indicator and control locations, respec-tively. No station effect was indicated.

13

l Bottom Sediments In bottom sediments, the concentrations of Cs-134 were below the detec-

tion limit of 150 pCi/kg dry weight in all samples. Cs-137 concentra-tion averaged 360 pCi/kg dry. No other gamma-emitting isotopes, except naturally-occuring, were detected in any of the samples analyzed. No i station effect was indicated.

4 c Fodder Gamma-emitting isotopes, except naturally-occurring beryllium-7 and potassium-40, were below their respective LLDs. No station effect.was

TABLE NOTATION a

This list does not mean that only these nuclides will be considered.

Other peaks that are identifiable, together twith those of the above nuclides, will also be analyzed and reported.

b Required detection capabilities for thermoluminesce.nt dosimeters used for environmental measurements are given in Regulatory Guide 4.13. ,. .

4 C

The LLD is defined, for purposes of these specifications, as the small-est concentration of radioactive material in a sample that will yield a net count, above system background, that be detected with 95% probablilty with only 5% probability of falsely con,cluding that a blank observation represents a "real" signal.

t For a particular measurement system (which may include radiochemical separation): ,

LLD =

4.66 sb

-E x V x 2.22 x Y x exp ( A At) where LLD is the lower limit of detection as defined above (as pCi per unit mass or volume).

sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute).

E is the counting efficiency (as counts per transformation).

V is the volume or mass of sample.

Y is the fractional radiochemical yield (when applicable).

A is the radioactive decay constant for the particular radionuclide.

At is the elapsed time between sample collection (or end of the sample collection period) and time of counting.

em 26

Table 5.0-3. (continued)

?

TABLE NOTATIONS (continued)

The value of sb used in the calculation of the LLD for a detection system will be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD.for a radionuclide determined by gamma-ray spectrometry, the background will include the typical contrib'utions of other radionuclides normally present in the samples (e.g., potassium'-40 in milk samples). .

Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other circumstances may render these LLDs unachievable. In such cases, the contributing factors will be identified and described in the Annual Radio-logical Environmental Operating Report.

1. O INTRODUCTION ,

The following constitutes the Annual Progress Report for the Radiological Environmental Monitoring Program conducted at the Fermi-2 Atomic Power Plant, Newport, Michigan. Results of completed analyses are presented in the attached tables.

Data obtained in the program are well within the ranges previously encountered in the program and to be expected in the environmental media sampled.

None of the media sampled contained radioactivity attributable to the opera- ,

tion of the Fermi-2 Atomic Power Plant.

For all gamma isotopic analyses, spectrum is computer scanned from 80 to 2048 kev. Specifically included are Mn-54, Co -58, Fe -59, Co -60, Zn -65, Zr-95, Nb-95, I-131, Cs-134, Cs-137, and Ba -La -140. Naturally occurring gamma-emitters, such as Ra daughters are frequently detected but not listed .here.

Potassium-40 is listed only if detected. Data listed as "<" are at the 4.66 sigma level, others are 2 sigma. Unless noted otherwise, the less than value

("<") for air particulates listed under "other Gammas" is for Nb-95 and may be higher or lower for other radionuclides.

All concentrations, except gross beta, are decay corrected to the time of collection.

I Grass was collected at Location F-18 in lieu of milk as of April,1985 due to the unavailability of milk samples.

Collection of milk at Location F-19 began on September 23, 1985.

0 4pendix A Interlaboratory Comparison Proaram 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 procepures 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 environ-mental sample crosscheck program for milk, water, air filter.s,- and food samples during the period 1982 through October 1985. This program has been conducted by the U. S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada.

The results in Table A-2 were obtained for thermoluminescent dosimeters (TLD's) during the period 1976, 1977, 1979, 1980, and 1981 through parti-cipation in the Second, Third, Fourth, and Fif th International Intercomparison -

of Environmental Dosimeters under the sponsorships listed in Table A-2. ,

Data Reporting Conventions 1.0. All activities are decay corrected to collection time. -

2.0. Single Measurements _ ,

Each single measurement is reported as follows:

xis where x = value of the measurement; s = 2a counting uncertainty (corresponding to the 95% confidence -

level).

In cases where the activity is found to be below the lower limit of detection L it is reported as ---

<L where L = is the lower limit of detection based on 4.66a uncertainty.

for a background sample.

3.0. Duplicate Analyses 3.1. Individual results: x1 i s1 x2 i s2 Reported result: xis where x = (1/2) (x1 + x2) s = \fs2+s2 3.2. Individual results: <L1

<L2 Reported result: <L where L = lower of L1 and L2 3.3. Individual results: xis

<L Reported result: x i s if x > L;

<L otherwise

I 4.0. Comoutation of Averaaes 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 x and standard deviation (s) of a set of n numbers x1, x2, Xn are defined as follows:

x=1n Ex E (*-*I2 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.

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 ex~ ample, 11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42.

I. J3.n_d __U s e Census J Bases A. Title 10 of the Code of Federal Regulations, Part 50, Appeidix I,Section IV. B.3 states that "The Licensec shall establish an appropriate surveillance and monitoring program to:

Identify changes in the use of unrestricted areas (e.g.,

for agricultural purposes) to permit modification in monitoring programs for evaluating doses to ind iv id u a ls from principal pathways of exposure."

B. The following requirements are from the Fermi-2 Plant Specific Tec hnic a l Specifications:

1. Section 3/4.12.2 - Land Use Census, states that "A land use census shall be conducted and shall identify within a distance of 8 km (5 miles) the location in each of the 16 meterological sectors of the nearest milk animal, the nearest regidence, and

~

ghe nearest garden of greater than 50 m (500 ft

) producing broad leaf vegetation."

2. Section 4.12.2 states that:

"The land use census shall be conducted during the growing season at least once per 12 months using .

that information that will provide the best results, such as by a door-to-door survey, aerial survey, or by consulting local agriculture authorities. The results of the land use census shall be included in the Annual Radiological Environmental Operating Report pursuant to Specification 6.9.1.7."

C. NE-5.14 -

Radiological Environmental Monitoring Program.

Section 3.2.3 states that " Nuclear Technology assures that an annual land use census is conducted per Reference 6.8.2 ( Re f e renc e 6.8.2 is Instruction NE-5.14.2 Land Use Census -

REMP)"
