SUMMARY

I This report was prepared by the Detroit Edison Company in compliance with the requirements of This !s a revised report and supersedes the U S. Nuclear Regulatory Commission (NRC) revision 0, due to incomplete sample results and program omissions from the initial report.

The Radiological Environmental Monitoring Program (REMP) at Fermi 2 was established by Detroit Edison in 1978. At that time the program was designed to 1stabilah a preoperational baseline. lne program consisted of monitoring air, drinking water, surf ace water, lake sediments, milk, vegetables, fish, and direct radiation in the environment surrounding Fermi 2 Fermi 2 became operational in 1985. The REMP has since been modified to assess any radiological impact upon the surrounding environment due to the operation of the plant Sampling locations which are most likely to Indicate any measurable radioactivity are called I

• indicator' locations. Data is also obtained from sampling locations which are distant from Fermi

2. These locations are areas that should not be affected by the operation of the p! ant and are called ' control' locations.

Throughout the year, the Environmental Assessment statt at Fermi 2 compares the indicator data with the control data. This ccmparison is used to determlne if there has been any measurable I impact to the environment which is related to operating Fermi 2. Any significant difference between the indicator data and the control data is reported to the NRC.

in 1990, Detroit Edison collected more than 900 environmental indicator and conttol samples I and contracted more than 1200 enalyses bs part of the REMP.

Initial analysis of two (2) sediment samples indicated trace levels of radioactivity just above the laboratory's lower limit of detection (LLD). The samples were reenalyzed with the result that only one of the samples indicated detectable radioactivity, The sample results were well below any regulatory reporting limits and were consistent with the activity released from the plant in liquid effluents, None of the other sample analysis in the REMP indicated radioactivity attributable to Fermi 2 I operations. Results showed that the radioactivity levels were similar to the preoperational levels Comparisons of 1990 operational data, pre 1990 operational data, and preoperational data I showed that the operation of Fermi 2 had no impact of any significance upon the environment in 1990.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGR AM I

REGULATIONS Title 10 of the Code of Federal Regulations (CFR) Part 50, Appendix I, " action IV.B requires that Detroit Ed: son establish an appropriate surveillance and monitoring prom 4.n to assure that radioactive I products released to the environment are kept at extremely low levels, Section 20.201 of 10 CFR Part 20 further requires that a licensee conduct surveys of levels of radiation or concentrations of ra dioactive products as necessary to show compliance with Commission regulations, I PREOPE3 AT10N AL PROGR AM The preoperational environmental monitoring program was established seven years before operating the Fermi 2 reactor. This preoperational program determined the existing levels of radiation and radioactive products occurring naturally and from man-made sources in the environment around the I Fermi 2 site. The program included continuous monitoring of direct radiation, radioactivity in air, lake sediments and water, drinking water, cow and goat milk, and local garden vegetables OPER ATION AL PROGR AM The elements that made up the preoperational monitoring program are still in effect today. The I preoperational program became the operstional program in June of 1985 when initial criticality was achieved for the Fermi 2 reactor, The sampling and analysis program in the operational phase still continuously monitora direct radiation, radioactivity in air, lake sediments and water, drinking water, I groundwater, cow and goat milk, and local garden vegetables.

QU ALITY CONTROL Detroit Edison participates in a Nuclear Regulatory Commission (NRC) approved interlaboratory comparison program In this program, simulated environmental samples are prepared by the Oustity Assurance Branch of the Environmental Protection Agency (EPA) and sent to the Fermi 2 REMP laboratory, The laboratory performs the required analysis and returns the results to the EPA The EPA performs a statistical analysis and comparison to known values and returns the results to the laboratory.

INTRODUCTION The terrestrial monitoring program provides continuous monitoring of the land environment surrounding Fermi 2, The program consists of monitoring the atmosphere, milk, grass, and l vegetables for radioactivity due to the operation of the plant. Also, the program monitors direct radiation in the environment surrounding Fermi 2. The following sections discuss the type of sample, analysis performed, and a comparison to previous years' data including preoperational data.

DIRECT R ADI AT10H Gemma racNtion is continuously monitored in the environment surrounding Fermi 2. Detroit I Edison deploi, thermoluminescent dosimatgs (TLDs) to measure this radiation. The TLDs are thoroughly tested to assure accurate measurements under varying environmental conditions be. ore being placed in the field. Environmental TLDs are exchanged and processed on a quarterly basis. While in the field, these TLDs are exposed to background radiation and. it measurable, gaseous effluents and direct radiation from Fermi 2. Indicator TLDs are located within a ten mile radius of the plant and control TLDs are located greater than ten miles.

The average exposure for indicator TLDs during the preoperational program was 17.3 mrem /Std Otr and 17.5 mrem /Std Otr for control TLDs. The annual means for indicator TLDs ranged from I 13.6 inRem/Std Otr to 21.0 mrem /Std Otr. The annual means for control TLDs ranged from 15.5 mrem /Std Otr to 21.9 mrem /Std Otr.

From 1985 to 1989 the average exposure for indicator TLDs was 16.9 mrem /Std Otr and 10.1 I mrem /Std Otr for cLntrol TLDs. The annual means for indicator TLDs ranged from 14 8 mrem /Std Otr to 20.3 mrem /Std Otr. The annual means for control TLDs ranged from 16 2 mrem /Std Otr to 22.2 mrem /Std Otr. As Figure 31 shows, the operational period from 1985 to 1989 was consistent with the preoperational program.

FIGURE 31 In 1990, the TLD monitoring program included fody six (46) TLDs for the first three quarters, and sixty three (63) TLDs in the fourth quarter, in tne fourth quarter, en additional seventeen (17)

TLDS were placed in the field to enhanco the direct radiation monitoring program. Eight (8)

TLDs were placed around the site boundary, six (6) were placed at schools within five miles of the plant and three (3) additional TLDs were placed bt the ten mile radius.

In 1990, the TLDs nearest the plant indicated a mean value of 16.0 mrem /Std Otr, The TLDs E considered not to be affected by operating Fermi 2, (i.e., control TLDs) indicated a mean value E of 13.9 mrem /Std Otr. The indicator TLDs had a mean value of 14.7 mrem /Std Ctr and ranged from 6.7 to 36.8 mrem /Std Otr. T 43 (the II.D with the h!ghest mrem /Std Otr value) read 36.8 mrem /Std Otr because it is located onsite adjacent to the Condensate Storage Tank (CST). The control TI.Ds ranged from 9.5 to 18.2 mhem/Std Otr. As Figure 31 shows, the average exposure for indir:etor and control TLCs was sihht!/ Icwor than previous years, including preoperational yests. Although the exposme; were lower than previous years, they are still consistent with the it.,ng-term trend.

From 1985 to 1989 the average gross beta for indicator samples was .025 pCi/ cubic meter and

.024 pCi/ cubic meter for coritrol samples. The annual mecn gross beta for indicator samples ranged from .021 pCi/ cubic meter to .034 pCi/ cubic meter. The annual i.e.. pross beta for g control samples ranged from .020 pCi/ cubic meter to .033 pCl/ cubic meter. In 1986, as shown g in Figure 3 2, there was a slight increase in gross beta activity and a .27 pCL/ cubic meter ' spike" in the lodine 131 activity. These elevated activity levels have been attributed to the nuclear accident at Chernobyl (U.S.S.R ) on April 26,1986. For the operational period from 1985 to 1989, excluding 1986, the alt sampling data is consistent with the preoperational data.

During 1990, two hundred and fitty nine (259) air particulate sarnples were collected and two l hundred forty nine (249) were counted for gross beta radioactivity. Five samples were lost at E the laboratory while being transferred from one storage facility to another. Five were cross-contaminated at the laboratory by a liquid sample while in storage. The average gross E bete activity was .025 oCi/ cubic meter for indicator samples. The average gross beta activity for 3

$ the control location was .024 pCl/ cubic meter, The range of the indicating locations was .010 pCi/ cubic meter to .060 pCl/ cubic meter. The range of the controllocation was .012 pCl/ cubic meter to .075 pCi/ cubic meter, s At the same locatians as the particulate filters, two hundred and fifty nine (259) charcoal filters were collected and two hundred fifty eight (258) were counted to determine the presence of iod:ne 131 in the atmosphere. One sample was lost at the laboratory while in storage. None of the filters showed detectable levels of lodine 131.

. Twenty (20) quarterly composites of particulate filters from each sampling location were counted. Composite samples are prepared by combining the wcGkly samples which wers obtained during the quarter at each of the air sarnple locations. One control sample showed 5 detectable activity for Sr 89 and two indicator sam tes showed detectable activity for Sr 89 Just E above the lab's LLO. This activity is most likely owe to statistical variation in sample counting.

Nine indicator samples showed activity for Sr.90 and three out of four control samples showed activity for Sr-90. Also, one indicator sample showed activity for Cs-137. The St-90 end Cs-137 activity detected in these samples is mostly likely due to residual fallout from past weapons testing. All other gamma or beta emitting radioactivity that was detected was due to naturally occurring isotopes.

I I Fermi 2 1990 Annual Radiological Environmental Monitoring Report Revision 1 I MILK AND ORASS SAMPLING r The m!!k and grass sampling portion of the REMP is the most important aspect of the program This is because the major radiation exposure pathway to the public is due to the consumption of milk from grazing animals (dairy cows or goats).

Milk is collected from two indicator locations and one control location monthly or bi monthly during the grazing season. The milk is analyzed for 1131, gamma emitting isotopes, and St 69/90.

Milk sampling did not begin until 1979 in the preoperational program During the preoperational 3 pecgram oniy 1131 and gemma emitting isotopes were analyzed From 1979 to 1964 Cs 137 g and natural K 40 were the only isotop(s detected in milk samples.

During the operational period between 1985 and 1987, the lab only analyzed for 1131 ;nd gamma emitting isotcpes in 1988 the REMP lab began to analyze for Sr 89/90. In 1986,1131 in activity concentrations ranging from .7 pCill to 37.5 pCill were detected in milk samples.

Also in the same year, Cs-137 in activity concentrations ranging from 6 0 pCill to 7.3 pCill were I detected in these samples. These activity concentrations have been attributed to the nuclear accident at Chernobyl (U.S.S R) on April 26,1986. For the operational period from 1985 to 1989, excluding 1986, the milk sampling data is consistent with the preoperational data.

During 1990, fifty-two (52) milk samples were collected from farms participating in the Fermi 2 environmental program. In May and June, six (6) samples, including the Quality Control sample, at all control and Mdicating locations were reported as having 1131 activity greater J. than the Fermi 2 Technica) bpecification LLO of 1.0 pCill. The range of these samples was 1,1

(

pCl/l to 17.8 pCill. After a detailed investigation, it was determined that the 1131 concentrations y g in milk for May and June were not due to operating Fermi 2. A summary of this evaluation is g included as Appendix B.

The control sample for July showed detectable activity for 1131 which is believed to be relatect I to the May and June activities. This sample is not discussed in the summary due to the Sample not being reported at the time of the investigation Some of the remaining samples showed detectable 1-131 at such low concentrations in both indicator and control samples that the activity is most likely due to statistical variation in sample counting One sample showed a detectable activity of 5.5 pCill for Co-58 The range for the lab's LLDs was 3 5 pCill to 11.0 pCi/l, This activity falls within this range and is most likely due t >

statistical variation in sample counting I 3-6 I ,

i I Fermi 2 1990 Annual Radiological I

Environmental Monitoring Report Revision 1 Two samples showed detectablo ac0vity for Co-60. One sample was 14.7 pCill and the other was 10.2 pCi/L The range for the lab's LLDs was 6.0 pCi/l to 17.0 pCl/l. This activity falls within this range and is also most likely due to statistical variation in sample counting.

Analyses of Sr-90 and Cs 137 showed activity in both control and indicator locations. Fermi 2 started sampling for St 90 in 1988 and the levels of activity reported for 1990 are consistent with previous years and are most likely due to residual fallout from weapons testing. Five samples l were reported having detectable activity for Cs 137 The range of these samoles was 3.52 pCill 5 to 7.06 pCl/l, The range for the lab's LLDs was 4.3 pCl/l to 13 0 pCill. The sample results were within or below this range and are mostly likely due to statistical variation or fallout from past weapons testing.

During March 1990, the family at the milk sampling control location ( 7512 N. Custer Rd. Doty Farm) sold their daily cattle and subsequently dropped out of the program. A new control location was identified in April at 9334 Finzel Rd. (Calder Farm). The Calder Farm location is 15.7 km distant from the reactor and at 287 degrees WNW, and is in approximately the sector with the least prevalent wind direction as determined oy 1989 ten and sixty meter annual wind reses. The Calder Farm was sampled for the firLt time in May for milk and grass.

In addition to milk sampling, grass samples are collected at the control location during each g sampling period. Also, grass samples are taken adjacent to the critical receptor location, N instead of milk samples, since this residence declines to participate in the REMP program. In 1983, Cesium-137 was detected in grass samples which was attributed to past weapons testing.

Also, in 1986 and 1987 Cesium-137 and lodine-131 were detected in various concentrations which were attributed to the Chernobyl accident.

E During 1990, twenty-nine (29) grass samples were taken with milk samples. All indicator g location samples showed no detectab e activity. One st.mple from the control location showed 42 pCi/kg for Cs-137 which was just obove the lab's LLD but below Fermi 2 Technical Specification LLD. The range of the lab's vlO for Cs-137 was 14 to 85 pCi/kg. This activity falls l M

within this range and is most likely due to statistical variation or fallout from weapons testing.

One control grass sample showed activity for Co 60 just above the lab's LLD and is most likely I due to statistical variation in sample counting. E I

Indicator wa*or samples are obtained at the Monroe water intake located approximately 1,1 miles south of the plant Detroit municipal water is used for the control samples which are obtained at the Allen Park water intake located I approximately 18.0 miles north of the plant. Drinking water samplos are coll 9cted on a monthly basis and analyzed for gross beta, strontium, and gamma emitting isotopes. Also, quarttily composites of the monthly samples are analyzed for tritium, See Appendix E for a discussion on I tritium in the environment.

Environmental Monitoring Report g Revision 1 g Drinking water sampling did not start until 1979 and did not include strontium analysis. The average gross beta for indicator drinking water samples, excluding 1981, during the preoperational program was 3.4 pCi/ liter. In 1981, as shown in Figure 41, the average gross beta was 9.8 pCilliter for indicator water samples. This elevated gross beta activity tes been attributed to an atmospheric weapon test by the Peoples Republic of China in late 1980, in 1960 and 1983 Cs-137 was detected at levels ranging from 5.4 pCi/ liter to 19 pCi/ liter. Additionally. l tritium was detected during preoperational years at concentrations ranging from 190 pCi/ liter to a 540 pCl/ liter.

From 1985 to 1989 the averaDe gross bots activity for drinking water indicator samples was 2.6 pCi/ liter and 2.3 pCi/ liter for control samples. In 1988 the REMP began to analyze for strontium and in that year Sr-90 was detected at a concehtration of 1.2 pCi/ liter. Also, in 1988 tritium was detected at a concentration of 338 pCi/ liter. For the operational period from 1985 to 1989, the drinking water sampling data is consistent with the preoperational data.

For 1990, the average gross beta activity concentration for drinking water indicator samples was l 2.9 pCi/ liter and 2.5 pCi/ liter for control samples. Indicator samples ranged from 1.9 pCi/ liter to E 4.5 pCi/ liter and the control samples ranged from 1.7 pCi/ liter to 3,1 pCi/ liter. Two indicator samples were reported by the lab as having detectable activity for Co-60. One sample was 6.38 and the other was 5.79 pCl/l. The reported range of the lab's lower limit of detection (LLD) for Co-60, however, was B.3 to 15.0 pCi/l. Since the reported ar.,tivity falls below this range, it is most likely due to statistical variance in counting due to the random nature of radioactivity g decay. g-Strontium was detected in both indicator and control samples. The average St-90 activity g concentration was .05 pCi/ liter for indicator samples and .07 pCitiiter for control samples, Also, g Sr.89 was detected in some samples just above the lab's LLD and is most likely due to statistical variance in sample counting.

Tritium was detected in three out of the four quarterly composite samples in both indicator and control samples The average tritium activity concentration for indicator samples was 221 pCi/ liter and 291 pCi/ liter for control samples.

For 1990, the drinking water sampling data is consistent with prior operational dats and preoperational data.

SURFACE WATER SAMPLING Detroit Edison continuously monitors surfac . at6r at two locations surrounding Fermi 2.

Indicator surface water samples are obtained u ine Fermi 1 water intake which is approximately I .3 miles south south east from Fermi 2. The control surface water samples are obtained from Trenton Channel Power Plant's cooling water intake on the Detroit River. This control location is approximately 11.7 miles north north east of Fermi 2. Surface water samples are collected on a monthly basis and analyzed for strontium s.nd gamma emitting isotopes. Also, quarterly composites of the monthly samples are analyzed for tritium.

I Surface water sampling started in 1979 and was analyzed for gamma emitting isotopes and tritium, During the preoperational program no gamma emitting isotopes, except for those naturally occurring, were detected. During this time period the average tritium concentration for indicator samplos was 323 pCi/ liter and 308 pCl/ liter for control samples.

From 1985 to 1989 tritium was detected in surface water samples at an average concentration of 236 pCilliter for indicator samples For this period no tritium was detected greater than the LLD for control samples. In 1988 strontium analysis for surface water began and in 1989 Sr 90 was detected at a concentration of 2.4 pCi/ liter in one indicator sample.

During 1990, twenty three (23) surface water samples were collected and analyzed. No plant related gamma emitting isotopes were detected m these samples. The average tritium concentration for indicator samples was 219 pCi/ liter and 239 pCi/ liter for control samples The I average St.90 concentration was .08 pCl/ liter for indicator samples and for control samples Also, Sr 89 was detected in both indicator and control samples just above the lab's LLD and is most likely due to statistical variance in sample counting. Two indicator samples showed detectable activity for Cs-137 just above the lab's LLD which is most likely due to tast weapons I testing.

For 1990, the surface water sampling data is consistent with prior operational data and I preoperational data.

Groundwater sampling did not begin until 1987. From 1987 to 1989 no radioac-detected in groundwater samples. 1 In trM, Cs-137 and tritium were detected in groundwater samples. Cr.-137 was detected in < $

sample at location GW-4 at an activity concentration of 7.7 pCi/ liter. Tritium was detecteo .. Yi i two well locations. At locatic n GW-4 the tritium concentration was 89 pCi/ liter and at location GW 1, approximately .4 miles south of the plant, the concentration was 99 pCi/ liter. The Cs-137 activity is most likely due to past weapons testing The tritium activity detected is most likely due to past weapons testing and from naturally occurring tritium.

SEDIMENT SAMPLING Shoreline and lake bottom sediments from five locations are collected on a semiannual basis. l There is one control location and four indicator locations. These samples are analyzed for u gamma emitting isotopes and strontium.

During the preoperational program there was not a control location and samples were not analyzed for strontium, Between the years 1978 and 1984 Cs 137 was detected every year except 1982. The average Cs 137 activity concentration for the preoperational program was 326 pCilkg. No other, except naturally occurring, gamma emitting isotopes were detected during this time period.

From 1985 to 1989, the average Cs 137 activity concentration was 233 pCi/kg. In 1989, Sr-90 was detected in both indicator and control samples. The Sr-90 average activity concentration for indicator samples was 159 pCi/kg and 308 pCi/kg for control samples. The activity found during this time period can be attributed to past weapons testing.

Fermi 2 1990 Annual Radiological g Environmental Monitoring Report g Revision 1 I in 1990, two lake sediment samples collected in Ms y showed detectable activity for Mn 54 I Co-60,2n-65, and Cs 137. One sample was taken at the Fermi 2 discharge line (S 2) showed detectable activity for Mn-54, Co-60,2n-65, and Cs 137. The other sampfe was taken at indian Traits Beach (S 4) down stream of the discharge line and showed detectable activity for Mn 54 I and Cs 137. The activity in these samples was just above the lower limit of detection and was well below reportable action limits. The two samples were retrieved from the laboratory and sont to a different laboratory for reanalysis.

A confirmatory sample was taken at S 4 on 4-17 91, and sent to the laboratory for analysis The results of this sample showed no activity above the lower limit of detection.

On May 2,1991, the dats for the October 1990 sediment samples was received These samples showed no detectable plant related activity.

I On May 10,1991, the results of the reanalyzed samples were received The sample taken down stream, Indian Trails Beach, showed no activity above the lower limit of detection. The sample taken at the discharge line showed detectable activity for Mn 54 and Co 60 at comparable concentrations as originally reported Liquid ef:luent data for the 4th quarter of 1989 and the 1st quarter of 19ED was reviewed The data indicated the total activity for Mn 54 was .02 Ci, Co-60 was ,02 Cl, and Zn-65 was .02 Ct for this period. Liquid effluent data from 1986 to 1991 is included in Appendix C.

Based on the effluent data and the sampic data, it has been determh.ed that the Mn 54 and Co 60 activity in the sample taken at the diacharge line (S-2) is due to liquid radwaste from Fermi 2. Also, it has been determined the clivity indicated in the sample taken down stream (S 4) can not be confirmed nor denied due to the lower limit of detection on the secor d count I being higher than the originally reported activity, in view of the extremely low activity levels found in these samples, they have negligible impact upon the envi.onment.

Cs 137 and Sr 89/90 were detectori in 1993 sediment samples in May, Cs 137 was detected in I both indicator and control samples at levels consistent with preoperational data and past operational data, in October, Cs-137 and Sr-90 were detected in both indicator ano control samples at levels consistem with preoperational data and past operational data. Also, St 89 was I detected in the October sarr.pten with high counting errors, in some cases the error was higher than the reported activity, and so the results are considered f alse positive I

Environmental Monitoring Report Revision 1 FISH SAMPLING l

Samples of fish are collected from Lake Erie at three locations on a semiannual basis. There are two control locations and one indicator location. Edible portions (fillets) of the fish are =

analyzed for gamma emitting isotopes and strontium.

During the preoperational program only naturally occurrinn isotopes t.nd Cs-137 were detected.

The average Cs-137 activity concentration for indicator samples was 35 pCi/kg and 42 pClikg for control samples. Preoperational samples were not analyzed for strontium.

From 1985 to 1989 Cs 137 was also detected in fish samples. 'Ihe average Cs-137 activity concentration for indicator samples was 46 pCI'kg and 56 pCi/kg for control samples. This activity is due to past weapons teating and is censistent with preoperational data. In 1989, Fe 59 was detected in one out of eleen control samples. This activity is most likely due to statistical variance in sample counting. During this time period, fish samples were not analyzed for strontium.

During 1990, twenty four (24) fish samples were collected and analyzed. Cs-137 was detected in both indicator and control samples. The average Cs-137 activity concentration for indicator g samples was 72 pCl/kg and 39 pCl/kg for control samples. In 1990, the REMP first began to E analyze for strontium in fish samples and Sr 90 was detected in both indicator and enntrol samples. The average St 90 activiy concentration for indicator samples was 129 pCi/kg and 77 g pCi/kg for control samples Also, Sr 89 was detected in some samples and is most likely due to g statistical variance it' sample counting.

For 1990, the fish sampling data is consistent with prior operational data and preoperational data.

LAND USE CENSUS I'

1990 LAND USE CENSUS As required by the U.S. Nuclear Regulatory Commission, Detroit Edison performs an Annual Land Use Census. The land use census is a formal, documented evaluation of the changes in the location of the nearest resident, dairy animals (goats and cows), and gardens. Locations were identified through Detroit Edison's continuing contact with neighbors of the Fermi 2 plant

as company personnel performed routine environmental sampling and observation. Using cartography and meteorology, each identified location was evaluated R ESULTS During the 1990 Land Use Census dairy cows were identified at 3979 Dixie Highway. Thi

location is approximately 2.8 miles from the plant in the WSW sector. As a result of this finding,

the critical recep*or was changed to this location (M-9). This change was based on the calculation of potential dose to the critical receptor using foliage cf.,vidumption rates of ecws vs goats, After a thorough evaluation, the critical receptor location was changed back to the original

' cati n at 42e2 post Road (u 73. Tnis change was due to tne factinat tne iodine transfer factor E is ten times greater for gosta th::', cows During this evaluation, two grass samples (i.e., one

{g sample period) were collected at 3979 Dixie Highway and are included in this report.

Labo, M 3 is at 3239 Newport Rd, and M 8 (control location) is at 9344 Finzel Rd. The M-3 (OC) samples are dup!!cato quality control l samples taken from the same allotment of milk.

The Formi 2 Technical Specification Lower Limit of Detection (LLD) for 1131 is 1.0 pCl/l.

I Anything equal to or above that is considered a detectable quantity. A detected quantity of from 1 to 3 pCl/l soon occasionally would not be unusual due to the counting statistics at that low level.

Two factors triggered the ovaluation: two sample results that were well'above the statisti-cal variation limits, and the frequency of the detectable results; six samples above LLD in .

one month.

The first stop was to determino reportability with one key point in mind; were the elevated I results due to plant offluents? A preliminary problem so;ving session was ho!d on Oc-tober 29. It was agrood in this session to exploro all possibilities of I 131 sourcos. A reactor scram on April 10,1990 appeared to be the most likely sourco of an 1131 releano of suffici9nt magnitudo to result in the concentrations seen in the May milk I samples. Subsequently apptopriato data was acquired to perform an evaluation, focus-Ing on tho 4/10/90 scram timo period.

I Additionally, calculations woro performod to determino the amount of I 131 that would have to t, ave boon released in order to soo the lovels reported in the milk samplos, and the concontration in cows' milk following a deposition on grvs.

Rased on an ovaluation of the sbovo information,it is concluded that the I 131 did not como from Formi 2 plant offluents. Thoro is no conclusive evidence pointing to where it I did como from. At this timo, the best assumption is that olthor:

1. The milk samples woro cross contaminated at the vendor laboratory

2. The instrumentation used at the laboratory was out of tolerance "high*, which would  ;

" Environmental Monitoring Report Revision 1 I Tr' tium in The Environment Evet since the earth has had an atmosphere containing oxygen and nitrogen, there has been tritium present in nature it is produced continuously by the interaction of cosmic rays with the I nuclei of oxygen and nitrogen atoms It also decays continuously so that a steady state has been reached for natural tritium. There is some uncertainty concerning ine amount of tritium arising from cosmic rays, but an average of the best estimates of the world inventory is about 50 megacuries (MC6) 81 MCI = 1 million Cl).

About 90 percent of the tritium from cosmic rays is in the hydrosphere (i e., in the ocean and other terrestrial waters ). Nearly all of the femainder is in the stratosphere, where the tritium is I actually produced by the cosmic ray reactions. From the stratosphere, the tritium gradually descends into the lower part of the atrnosphere by natural diffusion It is then brought down as tritiated water by rain or snow to the esfth's surface, and accumulates in the hydrosphere. As a result of natural circulation . namely, evaporation of water, cloud formation, and precipitation tritium is fairly uniformly distributed wherever water is present, including plants and animals I The testing of thermonuclear weaponsin the atmosphere, particularly between 1954 and 1963, brought about an increase in the amount of trittum on the earth. The total quantity introduced in this manner before the Nuclear Test Ban Treaty was signed, in 1963, has been estimated to be approximately 1700 MCl. Smaller quantities of tritium have been added since 1963 from the E atmospheric testing of nuclear explosives by China and France, but, on the whole, there has been a general decline due to radioactive decay. Nevertheless, by the year 2000 there will still remain at least 300 mci of tritium from this source.

The amounts of tritium that will be produced by the generation of electric power from worldwide nuclear teactor plants up to the year 2000 have been estimated by the Environmental Protection Agency (EPA). According to this estimate, the worldinventory of tritium in the year 2000 from nuclear power operations will be approximately 450 MC6.

In t990, the amount of tritium released to the environment by Fermi 2 effluents was 0 75 Ci. This is an extremely small fraction of the amount of tritium, when compared to 50 million Cl that are naturally occurring and 1700 million Ci from weapons testing, that already exist in the environment. Because this is such a small fraction of the total amount of tritium in the I environment surrounding Fermi 2, it is highly unlikely that an increase in tritium concentrations from Fermi 2 effluents could be detected in environmental samples 10 22 I
