I I I I. INTRODUCTION Ihis report contains a summary and analysis of the radiological environmental data collected during 1978 by the Environmental Studies Laboratory of the 11aine Yankee Atomic Power Company. I We measur e direct radiation in the station environs with LiF TLD chips. Maine Yankee personnel prepare, distribute, measure and calibrate these dosimeters. We refer all measurements of radionuclide concentrations to an of fsite environmental radioactivity laboratory. All the environmental samples were processed by the Yankee Environmental Laboratory (YEL) during 1978. The YEL participates in the EPA Interlaboratory Comparison Program (cross-check program). Section II of this report contains a list of all sampling stations used in 1978 as well as a tabulation of the media sampled at each station. Figures 1 through 8 indicate the location of the plant site, its topography and the 1(cations of the sampling stations. I Section III summarizes our environmental data. A computer program, EIOfAP, produces a digest of our 1978 measurements. Each environmental medium appears according to the alphabetical order of its medium code (c.f. Section II). At the top of each page, ETO!AP lists the units of measurement for each medium. The lef t hand column contains the radionuclide which is being reported, total number of analyses of that radionuclide, and the aumber of measurements which exceed ten times the yearly average background value. The latter are called "non-routine" measurements. The next column lists 4 I

lI 1 the average lower limit of detection (LLD) for each radionuclide as well L as the range of LLD's in the 1978 data. If all measurements happen to be positive ( i.e., above LLD), only a nominal LLD is printed. The LLD used l by the YEL for each sample, each radionuclide, is based on the methodology in the NRC Regulatory Guide 4.8 (Reference 1). 1I Those sampling stations which are adjacent to the plant and which could conceivably be affected by the operation of Maine Yankee are called " indicator" or " Zone 1" stations. Distant stations, which are beyond plant influence are called " control" or " Zone 2". l ERMAP calculates a set of statistical parameters for each radio nuclid e. This set of statistical parameters in:ludes separate analyses for (1) the indicator stations, (2) the control stations, and (3) the station having the highest annual mean concen*_. ion. For each of these three groups of data, ERMAP calculates; l 1) The mean value of positive concentrations (i.e., concentrations greater i l than the LLD); if no positive measurements exist, we print "LLD" in I the appropriate column. l 2) The square root of the mean square deviation. This is an estimate L of the sample variance. If only one positive measurement exists, ERMAP reprts the standard 95% countir.g error as an estimate of variance. 3) The lowest and highest positive concentrations; i l l 5 i r " ~ ~

4)

The number of positive measurements divided by the total number of measurements; 5) The probability, P, that the positive measurements are due to random occurrences of false positive errors. ERMAP assumes that the probability of an individual false positive measurement is 0.05; values of P are rounded and expressed in percent. Hence, the statement P=0 in ERMAP's output indicates that P is less than 0.50%. Section IV of this report contains our milk cow survey ret s. Section V discusses fallout from weapons' testing, and Section VI of this E 'I report discusses our own quality assurance program. i In the final sections, we analyze the results of our efforts in l 1978, calculate environmental radiation doses, and present our conclusions. l 1l E l l l l ) 6 1w F = -=

E IV. MILK COW CENSUS DATA E tiilk cow census was performed on June 12 and October 19. All the milk cows within 5 miles (8 Km) distance from the plant were tabulated -in Table - 1. During 1978, there was a change in one milk sample station. In October, the owner of Hutchins Farm sold most of his cows. Therefo re, Station Ut-11 was terminated in October. Baker Farm, Station Di-16, replaced Di-11 as the indicator station of milk sample. E-E [ [ [ l E E 46 p. m e I- ^ ____-__=_-.&:_-- - -~

A [ V. .A'D10S141ERIC FALLOUTS DURING 1978 On March 15, 1978, the People's Republic of China detonated a nuclear bomb. The fallout clouds arriven in the New England area on March 22 and 23, 1978. Even though this fresh fallout radioactivity was not manifested in the air particulate samples nor in the milk samples in our environment, { it was successfully detected in the aquatic plants along the Maine coast (Reference - 2). Sharp peak concentrations of fission product radionuclides [ (I-131, Ce-141, Ce-144, Ru-103, Ru-106, Zr-95, Nb-95, Te-132) in algae occured about one week af ter the arrival of fallout clouds. Also, the regional variation of fallout activity played a significant role. For example, the gross beta radioactivity of air particulate filters rose sharply among all air monitoring stations at the Pilgrim Plant (Reference 4) and a slight increase of air particulate gross beta radioactivity occured at the Yankee Rowe plant. The environmental samples collected during 1978 were also affected by the normal increase of radioactive particulates during spring and summer from the previous year detonation. This could be seen from the trend of [ air particulate gross-beta activity, which was slightly higher duiing spring { and summer and lower during fall and winter. The presence of Cs-137 and Cc-144 in terrestrial vegetation samples was likely due to both fresh and [ old fallouts. ( VI. QUALITY ASSURANCE PROGRAM Three separate quality assurance programs were performed during ( 48 ~

s 1978 to demonstrate the validity of laboratory analyses: (1) Yankee Environmental Laboratory (YEL) intra-laboratory quality control program, (2) the EPA Interlaboratory Comparison Program, (3) blind duplicate / replicate prog ram. YEL maintains an intra-laboratory quality control program to assure the validity and reliability of laboratory data. This includes quality control of laboratory instruments, use of reference standard sources, background and blank sample analysis, internal spike sample analysis and standardization of radionuclide carriers. The records of the quality control program are reviewed by the responsible cognizants, and corrective measures are taken whenever applicable. YEL also participates in the EPA Interlaboratory Comparison (cross-check) Program for those species and matrices routinely analyzed by the labora to ry. This provides an independent check of the accuracy and precision of the laboratory analyses. VII. ANALYSIS OF ENVIROM4 ENTAL DATA l l ( The analysis of our environmental data may be divided into three sections: airborne radioactivity, waterborne >:adioactivity and direct exposure (TLD) measurements. Accordingly, v shall discuss each environmental medium within one of these three major sections and correlate key environmental measurements with plant effluent data. E m +

7 [ 1. Airborne [ (a) Air Particulatas and Gaseous Radioiodine (I-131) E Figure 9 shows the gross behavior of radioactive concentrations of airborne particulates at Zone 1 and Zone 2 stations. Even though there was an atmospheric nuclear bomb test on March 15, these two graphs show { little indication of fresh fallout frcm this nuclear detonation. A seasonal trend shows increased gross beta radioactivity in Zone 1 and Zone 2 stations during spring and summer, and is due to the atmospheric intermixing between the upper and lower atmosphere. This effect is further demonstrated by the Cc-144 activity concentration in the air particulate filters (Figure 10). It was higher in both Zone 1 and Zone 2 stations during spring and Moreover, the mean concentrations of fission products (Ce-144, summer. Cs-13 7, Ru-103, Ru-106, Zr-95) at Zone 1 stations were about the same as l those at Zone 2 stations. There were four detectable I-131 activity concentrations in charcoal filters at Zone 1 and Zone 2 stations during 1978. All of them were the samples of the last week of March, when the fresh fallout arrived in the 1 New England area. However, the concentrations measured at those four samples { ere in the range of LLD. This suggests that the routine plant gaseous release of I-131 is not reutinely detected offsite in any significant quantity. [ 50 E L

I [ (b) Milk [ During 1978, there was no detectable I-131 in the milk samples among the indicator stations. There was one detectable I-131 in the milk sample at the control station (Zone 2), but the radioactivity concentration was in the range of LLD. The nominal value of LLD for I-131 in milk (low level counting analysis) is 0.09 pci/l. Even though the concentrations of Cs-137 and Sr-90 at the indicator stations were higher than those at the control station, there was little indication of effect from the plant gaseous release. For example, during 1978, the total gaseous release of Cs-137 from Maine Yankee was 2.56 KC1. { Using R. G. 1.109 (Reference 3) methodology and annual average D/Q at Station M-II, the expected Ca-137 concentration in milk at this station is several orders of magnitude smaller than the mean concentration measured in the milk. Similarly, with only 0.31 FCi annual release of Sr-90, its 'l concentration in milk is not likely from the plant's release during 1978. Figures 11 and 12 show the radioactivity concentrations of Cs-137 and Sr-90 in milk samples during 1977 and 1978. Notice that Station-ll was terminated in October 1978 (Section IV). The concentrations of Cs-137 { and Sr-90 in 1978 were in the range of fluctuation in 1977. Differences in animal diets and metabolisms may be related to the observed fluctuation. The above discussion suggests that the concentrations of Cs-137 and Sr-90 in milk samples are likely due to the weapons' testing fallout in the feed or forage. rL 53. G J. __.

[ (c) Food and Garden Crops Apples and cabbages were collected in September. The isotopic gamma analyses on those samples only revealed the naturally occurring radionuclide K-4 0. m l (d) Terrestrial Vegetation [ Terrestrial vegetation samples were collected in June and September. These samples consisted of mixed pasture grass. As usual the mixed grass [- sampeo were slighly contaminated with Cs-137 and Ce-144. The mean concentrations between Zone 1 and Zone 2 were not significantly different for these two radionuclides. Co-60 and Nb-95 were detected once out of 12 measurements at Zone 1 and Zone 2 stations. Their p-value (probability of false positive measurements) was 35%. This indicates that these positive measurements could be due to a random event. (e) Precipitation Water The 11-3 analysis of precipitation water samples did not show any significant difference between Zone 1 and Zone 2 stctions. ( f) Fresh Water Only K-40 and 11-3 were detected in the fresh water samples. For [ 11-3, the mean value of Zone 2 stations is higher than Zone 1 stations. E [i [ 56 l r

[' 2. WATERBORNE PATIMAYS (a) Estuary Water ( In November 1978, a change to Maine Yankee Technical Specifications was issued by the NRC (Amendment No. 42). Estuar; wa ter monitoring stations were changed from 6 to 3, and a continuous com.posite water sanpler was installed at Station WE-10, Plant Intake. However, all the old stations were continued until the end of 1978. The installation of continuous { composite samplers at the plant intake and outfall would allow one to quickly reveal any significant plant liquid release to the environment by comparing the radiological analysis of water samples from these two stations. The only signficantly detected radionuclide in the estuary water samples is H-3 measured in the second quarter samples at Station WE-15. These samples were actually the plant's circulating water taken directly i from the discharge forebay before the diffuser discharge. This undiluted discharge cannot be truly considered as a representative environmental water ( sam ple. When a dilution factor of 10 due to diffuser operation is applied to the Back River, the increase of H-3 level from the plant's liquid release is insignificant compared to the background H-3 level (approximately 350 1 60 pel/R )/ ( b) Aquatic Vegetation Several fission product radionuclides showed higher concentrations b in the samples collected on May 23. The increase could be attributed to the fallout from the nuclear bomb test of March 15, 1978, by the People's [ 57

~ L r l* Republic of China. This observation is supported by the study performed F L by Environmental Measurements Laboratory (EML) (Reference 2). EML measured the radionuclide concentrations in the Ibntsweag Bay seaweeds from Fbrch 1 th;ough June 1, 1978. In their study, fo r all fission produc ts (I-131, Cc-141, Cc-144, Ru-103, Zr-95, Nb-95, Te-132), sharp peak cone en trations L occurred about the same time as the arrival of fallout clouds ( April I s am pl es). Af ter this time, the radioactive concentrations gradually decreased and slowly leveled of f af ter one month. The activity { concentrations detected in our May 23 samples were comparable to or smaller than the values of EML's April 30 samples. (c) ! brine Organisms lL Fish, crabs, lobsters and mussels were the species collected during { 1978. Crabs and lobsters are categorized under Arthropods, while mussels are shellfish in our summary Tables in Section III. From the annual marine H L organism data, K-40, a natural occurring radionuclide, was the only I detectable radionuclide in the analyses. L (d) Sed imen t F L By comparing 1978 sediment data with previous year data, we notice that Stations SE-15 and SE-16 were still contain small Cs-134, Cs-137 and Co-60. These two stations were in the vicinity of the old liquid discharge po in t. Before 1975, routine liquid release from the plant was discharged in to this area with little diffusion. The installation of discharge diffuser m changed the liquid discharge from Bailey Cove to Back River. Figures 13 e L 58 F . = = _ = = _ - - - - - - - - - - - - - - - - - - - - - - - - - - -

I I 3. DIRECT RADIATION TLD's I Table 2 shows the yearly average exposure from direct gamma radiation in microrem per hour from eighteen TLD stations located on and off the Maine Yankee site. Zone I and restricted boundary stations exhibited monthly radiation exposures which range from 5.36 to 23.51 microrem per hour. This compares to the 7.44 to 21.88 range recorded at Zone II stations. Zone II stations had a higher average exposure rate than Zone I and restricted boundary sites. Although Zone II exhibited a higher exposure rate, the results from a t-test showed that the average exposure rates were not significantly different from each other. 1 I In conclusion, the direct radiation exposures at Zone I and restricted boundary stations are not different from Zone II stations.

I I I VIII. ENVIR0!MEhTAL DOSIMETRY The mean concentration of radionuclides observed in indicator and control station samples of air particulate filters, charcoal filters, drinking water, seafood, milk, and food crops were used to calculate total body doses to adults. The average individuals' usage factors were taken from UShRC Regulatory Guide 1.109 (October 1977). These usage factors are: 3 8000 m /yr of inhaled air 3701/yr of drinking water i 7.9 Kg/yr of seafood 1 110 f /yr of milk 190 Kg/yr of food products I The product of the mean radionuclide concentration and the usage factor yields the yearly radionuclide intake. The dose is calculated by using the dose conversion factors of USNRC Regulatory Guide 1.109. 1-131 doses to the thyroid were calcul u.5 4 separately from data for all nuclide. In addition, external whole body doses were measured with TLD's placed in indicator and control stations. I Table 4 summarizes the environmental doses from mean radionuclide j concentrations in indicator and control station samples. The whole body dose is almost entirely due to the contributions of Sr-90 in milk. I During 1978 total Sr-90 gaseous releases were 0.31 uC1. Using USNRC Regulatory Guide 1.109 methodology, the concentration of Sr-90 in milk from I 65 I

This indicates that the Sr-90 concentrations were not related to 1978 plant operation.. l TLD measurements indicate that nearby residents did not receive any measurable dose from plant operation.
