INTRODUCTION i

A pre-operational environmental radioactivity survey, initiated 7

in March 1960, was conducted by Nuclear Science & Engineering Corp-oration for the Philadelphia Electric Company in connection with Peach Bottom Atomic Power Station located in Peach Bottom Township, York County, Pennsylvania.

The initial loading of fuel into Unit 1,

a 40 MWe (net) high temperature, gas-cooled reactor, was started on February 5, 1966, and initial criticality was achieved on March 3, 1966.

Shutdown of Peach Bottom Unit i for decommissioning was on October 31, 1974.

For the purposes of this monitoring program, the j

beginning of the operational period for Unit 1 is February 5, 1966.

A summary of the Unit 1 pre-operational monitoring program is presented in a previous report.

(1)

Peach Bottom Units 2 and 3 are boiling water reactors each with a power output of 1050 MWe (net).

First fuel was loaded into Peach Bottom Unit 2 on August 9, 1973, criticality was achieved on

)

September 16, 1973, and full power was first reached on June 16, 1974.

The first fuel was loaded into Peach Bottom Unit 3 on July 5,

1974, criticality was achieved on August 7, 1974, and full power

_[

was first reached on December 21, 1974.

A pre-operational summary report (2) for Units 2 and 3 has been issued previously and sum-

=-

marizes the results of all analyses performed on samples collected i

from February 5,

1966 through August 8, 1973.

Detailed program

-=

description, station designations, reporting units, abbreviations, etc.,

are given in that report reflecting the program status at that time.

Where changes had been made from the original program, they J

are indicated in the appropriate sections of that report.

In general, any such changes have been made to increase the scope and specifi-city of the program to fulfill the program objective.

In 1967, site preparation for Units 2 and 3 at the Peach Bottom site was undertaken.

This has resulted in certain physical changes which required moving some of the original sampling stations.

Also, beginning in 1971, several sampling stations of significance to Units 2 and 3 were added to the program.

Some additions and changes have i

been made in the analytical requirements to reflect the latest recom-mendations of various government agencies.

These changes are detailed in previous reports.

i This report summarizes the results of analyses performed by Interex on samples collected during the period January 1 through December 31, 1978 in the Interex portion of the overall Peach Bottom program.

l The laboratory responsibility for performance of the environment-al radiation monitoring program has been modified several times since s

the Peach Bottom Unit 1 pre-operational program was first undertaken in 1960.

From the start of the program until the first quarter of 1969, a single laboratory located in Pittsburgh, Pa.,

was used.

This J

2339 074

I I.

INTRODUCTION was initially called Nuclear Science and Engineering Corporation and later became Nuclear Science Division, International Chemical and Nuclear Corporation as the result of a change of ownership.

During l

the first quarter of 1969, the program was transferred to ICN/ Tracer-lab, also part of the International Chemical and Nuclear Corporation E

and was performed by ICN in the Waltham, Mass.,

laboratory until the end of the first quarter of 1972.

At this time the program was trans-g ferred to Interex Corporation laboratories in Waltham.

The Interex 5

Corporation laboratory, which is presently carrying out sample collec-tion, analysis and report preparation, was moved to Natick, Mass. in May 1974.

During the various change-overs and moves, extreme care was taken to insure that continuity in all aspects of the overall program was maintained.

For example, samples were collected by the same in-dividual throughout the entire period.

The objective of this program is to acquire quantitative data for the concentrations of radioactivity in environmental media in the g

vicinity of the reactor site prior to and during operation of the 5

reactor plant.

These data are then examined to determine the extent of the impact of the plant or plants on the environment as reflected by any changes in the radioactivity levels from those observed during l

the pre-operational survey.

Generally, this is done by comparing the W

observed levels at those sampling stations which would be expected from various considerations to show maximum effects of plant operation g

to levels at stations remote from the site.

When possible, comparison 3

is also made to data obtained by various government agencies.

Since there are both natural and man-made radioactivity present in the en-vironment which are not related to plant operation, it is important to understand and adequately measure these contributions.

A number of radioactive elements occur in nature.

The most important of these are uranium and thorium, along with their respective radioictive decay products, and potassium-40 (K-40).

The concentrations of natural radioactivity vary with geo-g graphical location and with time and are primarily dependent on the 5

concentration of the respective elements in the constituents of the lithosphere.

Therefore, environmental radioactivity measurements must be performed at a number of locations representative of the general geographical area of interest.

E Other radionuclid es have been introduced into the biosphere as a result of the detonation of nuclear devices in the atmosphere.

A 3

significant fraction of these nuclides is generally disseminated throughout the upper atmosphere with the fine particulate debris from 3

the detonation.

Varying fractions of the nuclear debris eventually g

are deposited at ground level, principally in conjunction with precipitation.

After their arrival at ground level, the radionuclides enter soil or bodies of water, and varying fractions may enter drink-ing water supplies or be assimilated by edible plants or animals and thus enter the human food chain.

Natural radioactivities are also introduced into the human diet by analogous processes.

The deposition patterns of nuclear debris depend on many factors, ll 2339 075 e^oe 2

I.

INTRODUCTION including latitude, proximity to detonation sites, annual accumulation of precipitation, and the frequency, magnitude, location, and alti-tude of the detonations.

In the absence of detonatons, seasonal variations have been noted for several years, including maximum deposition rates in the spring and summer months and minimum rates in the late fall or early winter.

Distinct variations have also been noted in individual precipitations.

These latter variations have been attributed to variations of meteorological conditions prevailing during the respective precipitation events.

Since significant geographical and temporal variations are expected in the concentrations of both natural and man-made radio-activity in environmental media, it is necessary to acquire experi-mental values for their concentrations over a period of several years to achieve statistically-significant data.

Such an approach also provides data for seasonal or annual trends in the temporal behavior of these conc entrations and permits correlations of these trends with meteorological or climatological factors or with known injections of man-made radionuclides into the atmosphere.

II. PROGRAM DESCRIPTION The program as it existed at the end of the report period is described below.

Since its inception, several changes have been made to better accomplish the program goals.

A.

Environmental Monitoring Stations and Media Collected The environmental monitoring stations are described in Table II.1 and are shown in Figures II.1 through II.3.

In general, stations have not been moved significantly since the start of the program.

Two new sampling locations were created by installation of continuous water samples in the Units 2 and 3 intake and discharge canal.

The intake location is designated 1LL and first started sampling on January 16, 1978.

The discharge canal station 1MM was first sampled on January 1,

1978.

B.

Sampling and Analysis Program The types of analyses performed, the frequency of sampling and analysis, the locations of samples, and the number of analyses per statio. scheduled for each location as of the end of the report period, are given in Table II.2.

A summary of the analyses performed on samples representing J 'uary 1,

1978 through December 31, 1978 is given in Table II.3.

In addition to starting the analysis of samples from Stations 1LL and 1MM several modifications were made ingsampligg7and analysis cJJl Ui0 during 1978.

PAGE 3

I I I.

PROGRAM DESCRIPTION These changes are as follows:

1.

Sampling was discontinued at surface water station 1P and discharge water station IR.

2.

Fish sampling in Peters and Pequea Creeks (Stations 25A through E and 30A, B and C) was stopped.

3.

Shellfish sampling was terminated at all locations (Stations 9,

10 and 11).

4.

Well water sampling at Station 8 was eliminated.

5.

Gross alpha analusis of fish and vegetation samples was discontinued.

These changes were made after a thorough review of the program in late 1977.

Elimination of the above sampling and related analyses does not in any way compromise the program and its ob Jectives.

Detailed reasons for making the changes are given in an earlier report (3).

In addition, beginning with 1978 the data from the NMC gamma radiation monitors is not being reported as part of the environs radiation monitoring program since the normal environmental levels are below the sensitivity threshold of the instrument.

C.

Program Changes for 1979 As a result of further analysis cf the results of the Peach g

Bottom program several changes will be made in 1979.

None of these g

changes involved the PBAPS Tech Spec program.

Sampling and analysis of silt from Station 4C will be stopped l

and replaced with sampling at a new station, 4J.

Previous studies W

have found that sedimentation can occur at closer range to the PBAPS canal discharge than 4C.

Therefore, if any plant effect is present, g

it wi"1 be evident at 4D.

The new station is at the nearest shore-g line recreation area downstream and is consistent with the latest NRC recommendations.

I Water samples from Station IT will no longer be collected.

This station is in the discharge canal upstream from the current rad waste discharge. Sampling is done at the canal exit.

All current analyses on soil will be performed semi-annually rather than quarterly. In addition gross alpha analysts will be g

discontinued on all soil samples. Soil is a poor media to sample g

because of the high natural background. Sampling of soil is no longer recommended by the NRC. Some soil analyses are being con-tinued due to existing Tech. Specs.

Radiochemical analysis for St-89, Sr-90 and Cs-137 in fish will}} ](( PAGE 4

~ II. PROGRAM DESCRIPTION be eliminated. Data from operating reactors indicates that radio-strontium is not a significant contributor to the dose to man. This ^ is supported by data from PBAPS. The NRC no longer recommends radio-strontium analysis. Cs-137 is measured to an appropriate level by GeLi measurements, which are made on each sample. Gamma spectra on air particulate composites will be measured using GeLi spectrometry rather than Nal. This will result in better resolution of nuclides present as well as increased sensitivity. Cs-134 will also be reported with an MDL below 0.008 pCi/ cubic meter. These changes reflect the latest NRC recommendations and elimi-nate analyses which contribute little to the goals of the program. The ability of the program to detect releases from PBAPS into the environment is in no way compromised. on ,d m [JU/ / PAGE 5

I. PROCEDURE

S Detailed sample collection and handling procedures and reporting procedures are given in a previous report (2). The sample preparation and analytical procedures as well as equipment specifications are also given in an earlier report (3). Three changes were made in the analytical procedures for 1978. The c oun t ing of radiochemically separated cesium in milk was done using a GeLi detector rather than a low background beta coun6er. Since nuclear power plant releases contain Cs-134 in addition to Cs-137, while fallout from nuclear testing does not, it is important to measure the two isotopes separately. These nuclides are now being measured individually using the GeLi system. The initial portion of the procedure used to separate I-131 from milk was also changed. An aliquot of ion exchange resin is added to the milk samp le and stirred for at least two hours. The milk is then decanted and the resin washed to remove the last traces of milk. The oripinal procedure (3) is then followed starting at step 4. An ultra-1cw backgruynd I-131 counter was put in operation during 1978 and was used for counting approximately half (second and third quarter) of the milk samples. One of the detectors was out for repairs during the fourth quarter. The system detects the I-131 gamma rays with a well-type NaI detector and the I-131 beta with a plastic scintillation detector. The gamma detector output is put through a single channel analyzer, which generates a pulse when a gamma event corresponding to.31 to 41 MeV is measured. A count is recorded when a beta pulse is in coincidence with the analyzed gamma pulse. The separated PdI2 is filtered, drieu and weighed as was done previously. The filter paper is placed on a piece of sticky paper, precipitate side up. The precipitate is then covered with a thin piece of plastic wrap which adheres to the piece of sticky paper around the edges of the filter paper. For counting the mounted sample is placed f ac e-up in the gamma detector well. The beta detector is then inserted into the well to rest flat on the sample. The system typically has an efficiency of 10 percent and a background of 0. 05 cpm. 2237 092 PAGE 19

I I IV. DISCUSSION OF RESULTS The results obtained from the program are presented in the data tables and figures following this section and at e discussed below according to sample type. In this report, resulta, of analyses which are performed on ashed samples are reported in units of pCi/g original sample in addition to pCi/g ash. This is done to enable one to more easily estimate doses to man by reporting concentrations of radio-g activity in food products, as determined by the radiation monitoring 3 program, in terms of the sample state which is eaten by man. The results reported in these units, however, offer poorer comparisons of data because biological variables, such as water content, greatly affect the results. Results reported as radioactivity concentrations in terms of the ashed weights eliminate these variables and put the data on a more uniform basis for comparisen. For this reason, the graphs in this report which are intended to show comparisons of con-centrations of radioactivity between locations and time periods illustrate data reported in terms of the ashed weight, not the 3 original sample weight. 5 All results are given with an error corresponding to two standard deviations in the net count rate except for K-40 which is generally 10% when significantly above the detection limit. Results which are less than the calculated error are reported as less than (<> the value corresponding to the error. In calculating averages, results reported as "less than" a value are included as that value. The average of a series of numbers which g contains at least one real number is given as a real number. If all 5 of the numbers in a series to be averaged are "less than" numbers, the average value is given as a "less than" value. The deviation listed with means is equal to two standard deviations of the data comprising the mean. In the discussion of data, general trends in the data are g stressed as are comparisons of results from stations which would most W likely be affected by Peach Dottom Atomic Pou Station (PBAPS) operation, with data from those which are more remote from the site. Because of the presence of generally lower levels of radioactivity in the environment compared to earlier periods of major atmospheric nuclear testing, precise trends tend to become obscured in the normal variability of data. There were two atmospheric nuclear weapons tests during 1978 both by the Peoples Republic of China. The first test on March 14, 1978 g was seen in air particulate, milk, precipitation, and rabbit samples g using the techniques normally employed in the PDAPS program. The test on December 13, 1978 was not seen in samples from the PBAPS program or by beta measurements on samples taken nationwide as part of the ERAMS PAGE 22 2339 095 g

IV. DISCUSSION OF RESULTS network operated by the EPA. A few air particulate filters from the ERAMS program from central United States showed traces of I-131 when examined by GeLi spectrometry. A. AIR PARTICULATES The values of the concentrations of gross beta radioactivity observed in air particulate samples are listed in Tables IV.1.1 through IV.1.4 and are presented graphically in Figures IV.1.1 through I V.1. 5. Comparative available EPA data are given in Table IV.1.5. Gamma spectral analyses are given in Table IV.1. 6. For comparative purposes, stations have been divided into three groups. Group I, which is on the Peach Bottom site and closest to the plant release points, consists of Stations 1 A, 1B, and 2. Group II rings the site at further distances and consists of Stations 3A, 4A, 4B, 5, 6B, 14, 15, 17, 31, 32, 33A, and 38. Group III, which is in Philadelphia, Pennsylvania serves as a reference group and consists of Stations 12A and 12D. Gross beta radioactivity concentrations showed the effects of the March 14, 1978 test superimposed on the typical trend seen in most earlier years. The maximum monthly average concentrations, exclusive of those months influenced by the March test fallout were about O.1 - 0.2 pCi/m3. These are lower than the values of 0.4 - 0.5 pCi/m3 seen in 1977 and are indicative of a lower atmospheric inventory of radio-activity as would be expected from the limited testing. The maximum values seen in individual March samples were about 1.5 pCi/m3, similar to values resulting from other recent tests. As can be seen from Figures I V. 1. 1 and IV.1.2, there was no significant difference between the values obtained for the three groups of stations indicating no effects due to PBAPS operations. For comparison, data from the Environmental Protection Agency (EPA) (4) are presented in Table IV.1.5 and shown on the long term plots in Figures IV.1.3, IV.1. 4, and IV.1.5. The values observed in the Peach Bottom program are somewhat higher than those seen at the EPA station in Harrisb urg, Pennsylvania. The difference in results is apparently due to differences in laboratory techniques and is not attributable to PBAPS operation because it exists for all three groups. The EPA data also exhiS it the same trend as the PBAPS data. The EPA values listed in Table IV.1.5 are based on laboratory measurements in contrast to the less sensitive field estimates available for some periods before 1974. Figures IV.1.3 through IV.1.5 show comparable trends and values over the period 1966-1978 for all three groups of stations even though the composition of the groups has been changed by adding more sampling stations. This would indicate that the distribution of 7 ' l( PAGE 23 as

I I V. DISCUSSION OF RESULTS activity over the entire area is relatively uniform and is not affected by PDAPS. Gamma spectrum measurements are made on monthly composite samples from each station. These samples generally consist of all weekly samples for the month from the given station taken together. Results or these analyses are given in Table I V.1. 6. Other than Zr-95 and Nb-9S from nuclear test fallout and naturally-occurrino De-7 and K-40 no nuclides were detected by NaI gamma spectrometry. The observed values tended to follow the same trend as was found for gross g beta radioactivity concentrations. Measurable values were similar at 5 all locations. No contribution from the operation of PDAPS is indicated. D. PRECIPITATION The concentrations and surface densities of gross beta, Sr-89, Sr-90, and Cs-137 radioactivity in precipitation samples collected at Stations l A, 1D, and 4M are presented in Tables IV.2.1, IV.2.2, and g IV.2.3. Results from the EPA stations in Harrisburg are given in 3 Table IV.2.4. Most of the radioactivity in precipitation samples is in the form of particulates which are washed oct of the air by rainfall and collected in the sample containers. Since most of the particulate material is washed out in the initial part of a rainfall, the surface l

density, i.e.,

pCi/m2, is usad in addition to concentration (pC1/1), W because it tendn to minimize the effect of sample volume. Lack of complete correlation with air particulate values comes about because rainfall general.' ' 7e s not occur at frequent intervals. The dependence of the -tivity levels on the precise conditions occurring at the start of i rainfall can cause wide variability between samples even whr over limited geographical areas. The March 197L icar test produced increases in gross beta radioactivity c on c er. - Jions in the March and April samples from all g locations. The March.anthly values were somewhat above 100 pCi/l m and 10000 pC1/m2. April values were significantly lower. Excluding the March and April results, the values for gross beta radioactivity monthly concentrations observed in samples collected at Stations lA and 3D show an increase reaching maxima during the summer at values cf about 15-30 pCi/1. The surface densities values were generally a few hundred to a few thousand pCi/m2. There did not appear to be any discernable difference between locations. The values observed were similar to those seen in earlier years and are in the range of preoperational data. ~ The values of monthly gross beta radioactivity concentrations observed in the precipitation samples collected at Station 4M are PAGE 24 ~7' 1 ~0 7 0

IV. DISCUSSION OF RESULTS similar to those from samples from Stations 1A and 1B except that they are generally slightly lower. This has been the case since 1974 and was seen in several years during the preoperational period. EPA data from Harrisburg, Pa. presented in Table IV.2.4 show concentrations and surface densities of gross beta radioactivity. The higt March values are evident. The values are generally lower than the values seen in this program. Prior to July 1973, the published EPA values were the results of field measurements. Since then, laboratory measurements have been reported. This changeover had the ef f ec t of decreasing the general level of reported monthly mean values due to an increased analytical sensitivity. The reason for the difference between data from this program and the EPA's is probably due to a difference in analytical procedure. Sr-89 radioactivity concentration was barely detected in the June sample from Station 1A. This is consistent with the absence of fresh nuclear weapons test debris as evidenced by the air partsco-late data. Sr-90 radioactivity concentrations were generally measured to be between a few tenths and 2 pCi/1. Surface densities ranged from tens to about 200 pCi/m2. These levels are comparable to what has been observed in previous periods. Cs-137 radioactivity concentrations and surface densities at Stations 1 A, 18, and 4M as given in Tables IV.2.1 and IV.2.2 are generally less than 2 pCi/l or 150 pCi/m2. Station 4M tends to be somewhat lower than Stations 1A and 18 as was explained above. = The observed radioactivity concentrations at Station 1A, 1D, and 4M show the extreme variability typical of precipitation and collectively do not indicate any contribution from the operation of PBAPS. C. SURFACE WATER AND DISCHARGE WATER The concentrations of gross alpha and gross beta radioactivity in the soluble and insoluble fractions of surface water and discharge water grab samples are given i r. Tables IV.3.1 and IV.3.2. Similar values for the composite samples from Stations 1LL, 1MM, 4L, and 6I are given in Tables IV.3.3 and IV.3.4. Mean radioactivity concentra-tions are given in Tables IV.3.5 and IV.3.6. Comparative monthly and annual values are presented in Figures IV. 3.1 through IV.3.6. No measurable alpha radioo-tivity was found in the soluble fractior, in any of the samples. The gross alpha radioactivity con-centrations in the insoluble fraction were generally a few tenths of a pCi/1 with two values as high as 5 and 7 pCi/1. The latter values were associated with samples which had large amounts of suspended material. 2339 098 PAGE 2"

I I V. DISCUSSION OF RESULTS I Data for gross beta radioactivity concentration in composite s mples from Units 2 and 3 intake and discharge are shown in Figures g IV.3.1 and IV.3.2. Similar to results from other stations most of g the soluble fraction values were at or slightly aLove the detection limits. The insoluble fractions generally were higher at Station 1 MM, g however, except for the result from the January composite, they were 5 within the range of values obtained from Station ILL and other stations. An examination of the weights of the insoluble fractions from both locations shows very good correlation between those weights l and the observed radioactivity concentrations. The January samples W from Station 1MM contained almost 1g of insoluble material. The February and April samples from the same station contained about 0.2 g and 0.4 g respectively. The January sample from Station 1LL had a 5 weight of about 0.25 g and the March sample 0.1 g, similar to weights found in samples from Station 1MM which showed radioactivity levels of about 2 pCi/1. It would thus appear that the higher levels seen at Station 1MM are due to the naturally-occurring nuclides in the suspended sediment. When compared on a per gram basis Stations 1MM and ILL have very similar radioactivity concentrations. Composite wa t e r samples from Stations 4L and 6I are shown in Figures IV.3.3 and IV.3.4. The gross beta radioactivity concentra-g tions for Me4" ' ar i t ans are similar to each othat and to the other 5 locations sampled. The correlation between the weight of the in=el-uble fraction and the observed adioactivity is similar to that dis-l cussed above for Stations 1MM and ILL indicating that the increased levels found arly in the year at Stattion 4L are due to naturally- = occuring nuc1 h es. There was generally no apparent difference between the composite samples and the grab samples taken near the same loca-g tion with the apparent exception of the insoluble fraction from W Station 4F. This location generally has more insoluble material because it is a deep sampling point and its radioactivity concentra-tions reflect the naturally-occurring nuclides in the sediment. Annual mean gross beta radioactivity concentrations in surface water samples from Stations 6A, 4F, and 13A are given in Figures IV.3.5 and IV.3.6. As has been the case in the past, these stations have relatively uniform concentrations. The slightly higher values in the insoluble fraction at Station 4F are attributable to the g greater amount of sediment in the sample. The majority of the 3 individual higher values in the insoluble fractions are associated with larger amounts of sediment. I The similarity of results among stations shows no indication of any maasurable radioactivity in receiving water bodies due to the operation of PDAPS during the period of this report. D. WELL WATER Results of the analysis of well water samples for pross alpha, 9l)'O 000 Ls / U/ PAGE 26 8

I V. DISCUSSION OF RESULTS gross beta, S r-89, Sr-90, and Cs-137 radioactivity and uranium are given in Tables IV.4.1 and IV.4.2. Radioactivity in well water samples generally arises from the leaching of naturally occurring nuclides from the rocks and soil past which the water flows. As levels of the water table changes, varia-tions can be encountered in the flow pattern followed by the water in a given well. This can cause changes in the radioactivity content of the water since the leachability of the radioactivity varies as the permeability of the soil and rock encountered by the water differs. An additional factor which can change radioactivity concentration is the well usage. A well which is used at a constant rate tends to maintain a more constant radioactivity level. Lack of usage can cause buildup of radioactivity concentration if conditions very close to the well are amenable to leaching, or it can cause concentrations to decrease i f wa t er from the major sources of the radioactivity does not reach the well when samples are taken. Gross alpha radioactivity concentrations were found to be below the detection limit of several tenths of a pCi/1. This is consistent with data from the Units 2 and 3 preoperational period. All but 2 of the gross beta values were below the detection limit of approximately 2 pCi/1. The two measured values were 3 +/- 2 pCi/1. Uranium was also detected in about half of the samples from on-site and off-site locations. The levels in general are similar to those seen in previous periods. A relatively high concentration of 0.6 ug/l was seen at an off-site station. Uranium is naturally occur-ring in most rocks and is not of plant origin. No Sr-89 or Cs-137 radioactivity was detected in any of the samples except for Cs-137 in one sample from Station 1U. Hydro-logical considerations make it improbable that the radioactivity is of plant origin. Very low concentrations of Sr-90 were found in several of the samples from both on-site and off-site stations. Because of the small net count rates it was not possfble to confirm the V-90 decay so the c oncentrations may not be real. Mean values as given in Table IV.4.2 show no significant differences between wells close to or on site and those at distant locations indicating no measured radioactivity from the operation of PDAPS. E. SOIL The results obtained for concentrations of acid-leachable gross alpha, gross beta, K-40, net beta, Sr-90, Sr-89, and Cs-137 radio-activity in soil samples are given in Tables IV. 5.1 and IV. 5. 2. PAGE 27 2339 100

I E I V. DISCUSSION OF RESULTS I Mean values for Sr-90, Sr-89, and Cs-1J7 are plotted in Figures IV.S.1 through IV.S.3. Alpha and beta radioactivity are found in soil samples because of the presence of naturally-occurring nuclides in the uranium and l thorium series and K-40, and from nuclides present in fallout from nuclear testing. Specific analysis for Sr-89, Sr-90, and Cs-137 which 5 are normally present in fallout are done to measure these nuclides in the presence of the larger quantities of naturally-occurring radio-activity. The gross alpha radioactivity concentration was generally a few pCi/g dry weight, with the majority of the values below 2 pCi/g dry weighu The observed differences are most often the result of different soil composition at the various locations. Net beta radioactivity, which was detectable in the majority of samples, was between 2 and 7 pCi/g dry weight. These values are with-in the range of normal variability. The majority of the Sr-90 concentrations were grouped in a range of a few tenths of a pC1/g dry weight. All of the values are consistent with previous annual averages. As a result of the atmospheric nuclear testing Sr-89 was found in many of the samples analyzed, especially those taken early in the year. Values were generally a few hundredths of a pCi/g dry weight and were not significantly different between locations. The concentration of Cs-137 generally was several tenths of a pCi/g dry weight and measurable in all samples. All values were with-in the range of preoperational data. Values obtained from samples taken at the Peach Dottom site are comparable to or lower than the average values from the surrounding sampling stations indicating no measurable radioactivity in soil from PBAPS operation F. SILT Tables IV.6.1 and IV.6.3 give the analytical results and annual means for concentrations of acid-leachable gross alpha, gross beta, Sr-89, St-90 and Cs-137 radicartivity for salt samples. gel 1 gamma g spectrum analysis results are given in Table IV.6.2. Gross beta and 3 specific nuclide activities observed at several stations are presented in Figures IV.6.I through IV 6.4. Silt samples are expected to contain naturally-oc, curring radio-activity, as discussed above for soil samples, in addition to any other activity introduced into the aquatic environment which would g settle ento or be absorbed by the silt. As can be seen by comparison W PAGE 28 c A i0i n,,

IV. DISCUSSION OF RESULTS of the data in Tables IV.6.1 and IV.S.1, the activity levels in silt generally are similar to those found in soil, although soil may tend to be somewhat higher due to the presence of fallout from previous atmospheric nuclear weapons testing. The concentrations of gross alpha radioactivity at all sampling stations was generally a few pCi/g dry weight and are well within the range of variability observed in PBAPS Units 2 and 3 preoperational data. Gross beta radioactivity concentration was similar to gross alpha concentration. The results and variations between stations are consistent with the PBAPS Units 2 and 3 preoperational period. Sr-90 concentrations occurred within the approximate range of

0. 01 to 0.07 pCi/g.

All results are within the range of variability observed during the PB APS Units 2 and 3 preoperational period. Sr-89 was measured in two of the samples, most probably due to the atmospheric nuclear testing by the Peoples Republic of China All samp les analy zed showed Cs-137 generally at low levels of a few tenths of a pCi/g dry weight which is well within the range of PBAPS preoperational data. Any apparent discrepancy between the radiochemistry values and gamma spectrum values most probably accors because the gamma spectrum values given in Table IV.6.2 are more representative of the whole sample, which is inhomogenious, rather than only the aliquot analyzed. The differences between stations. are discussed below under gamma spectrum analysis. Figures IV.6.1 and IV.6.2 compare Stations 4D, 4C, and 4T which are at increasing distances from the PBAPS discharge. There does not appear to be any correlation of the observed levels with particular locations when normal variability is taken into account. The pre-operational data show approximately the same spread in values and values of similar magnitude to those seen during 1978. A comparison of Stations I BB, in the discharge canal down-flow the liquid rad-waste discharge, and Station 6F, above Holtwood Dam, in Figures IV.6.3 and IV.6.4 indicates no pocitive addition of radio-activity by PBAPS operation, when normal variability is taken into account, except for cesium as is discussed below. Gamma spectrum analysis showed primarily the presence o f K-40 and the U, Th series as represented by Ra-226 and Th-228 respective-ly, all of which are naturally-occurring and Cs-137. Cs-134 was found in some samples from Stations 1BB, IX, 4C, and 4D and is most likely from PBAPS operation because it is a reactor generated product. Nb-95 and Ru-103 commonly found in atmospheric nuclear testing fallout were found in several samples. The overall similarity of results between locations and with the PAGE 29 2339 102

I I IV. DISCUSSION OF RESULTS I preoperational data indicates no addition of radioactivity due to the operation of PDAPS except for very small concentrations of Cs-134 g near the plant discharge water system. If it is assumed that all g cesium found is due to PDAPS releases, a dose calculation using the USNRC Regulatory Guide 1.109 model and assumptions results in a calculated dose of 5.63 E-3 mrem to a teenager's skin. This calcula-l tion conservatively assumes that the teenager was exposed to the W maximum concentration found for the entire exposure period. Silt sampling stations 4C and 4D have been labeled incorrectly in the 1973 through 1977 reports. These stations were sampled such that the reported locations were reversed from those actually sampled. The long term plots (Figures IV.6.1 and IV.6.2) have been corrected. There are no major differences in radioactivity concentrations between the stations, so the conclusions in previous reports do not change. G. FISH The results of the analysis of fish samples for concentrations of g gross beta, K-40, net beta, Sr-89, Sr-90 and Cs-137 radioactivity are g given in Tables IV.7.1 and IV.7.2. Gamma spectrum data are presented in Table I V.

7. 3.

Mean values are presented in Tables IV.7.4 and IV.7.5. Sr-90 and Cs-137 concentrations are plotted in Figures IV.7.1 and IV.7.2. Net beta radioactivity generally ranged from <10 to 50 pCi/g ash g with the majority of the results below 20 pCi/g ash. The values were 3 well within the range of PDAPS preoperational data. Sr-89 was barely detected in a few fish. This is most likely due to atmospheric nuclear test fallout. l Sr-90 radioactivity concentration as determined in samples from all locations was generally a few tenths to a few pCi/g ash w corresponding to several hundredths of a pCi/g original sample. The concentraticn of Cs-137 radioactivity measured in samples from all stations was between aporoximately 0. 1 and 4 pCi/g ash with the majority of values several tenths of a pCi/g ash. Corresponding values for the original samples were 0.006 to 0.12 pCi/g with the majority of values a few hundredths of a pCi/g. Stations 1EE and 4J, as a group of stations which could be g affected by FBAPS operation, and Stations 6H and 6J, which are 3 above Holtwood Dam and therefore unaffected, are compared in Figures IV.7.1 and IV.7.2. There is essentially no difference in the range of concentrations for St-90 radioactivity in fish from the two groups of locations as can be seen from Figure IV.7.1. As has been the case since 1976, the quarterly mean Cs-137 concentrations tended to be l higher at Stations 1EE and 4J. The levels found in catfish, which are bottom feeders, were again higher than those found in white c.appie. W ^1 1n7 "~"/ iJJ PAGE 30

F I V. DISCUSSION OF RESULTS Gamma sp ectrum analyses as shown in Table IV.7.3 generally indicate the presence of only naturally-occurring K-40 and Cs-137 from nuclear test fallout. No Cs-134 was detected in any samples. Zn-65 was barely detected in a sample from Station IEE which is in the plant water discharge system. No Zn-65 was found in fish caught at any off-site location. Examination of the data for fish indicates no apparent difference in radioactivity concentration between species or station except for cesium concentrations. The species mean values given in Tables IV 7.4 and IV.7.5 indicate a higher concentration of Cs-137 in catfish Examination of data from all stations in Tables IV.7.1, IV. 7. 0, and IV.7.3 indicates essentially no difference other than normal variability between off-site stations for all nuclides except cesium There is a small amount of Zn-65 in one sample from the onsite environment probably due to the operation of PDAPS. The maximum doso calculated using the USNRC Regulatory Guide 1.109 model and assump-tions is 0.21 mrem to a teenager's liver. The actual dose due to PDAPS operations is much less than 0. 21 mrem since only one fish was found to contain Zn-65 and Cs-137 is present at all stations from sources other than PDAPS. H. VEGETATION The concentrations of gross beta, net beta, K-40, Sr-89, Sr-90, and Cs-137 radioactivity are given in Tables IV. 8.1 and IV. 8. 2 for vegetation samples. Mean values are in Tables IV.8 3 and I V. 8. 4. Figures IV. O.1 and IV.8.2 show annual mean values for Sr-90 and Cs-137 radioactivity concentrations. The concentrations of net beta radioactivity are similar for all stations and appear to have approximately the same spread. Measur-able values ranged from about <30 to 150 pCi/g ash with the majority of values nearer the low end of the range. All results are in range measured during the PBAPS Units 2 and 3 preoperational period. Corresponding values were in the general range of a few tenths to about 3 pCi/g original sample. The raw weight to ashed weight ratto varies markedly between samples as would be expected from the different water content of various types of vegetables and vegetation. Sr-90 radioactivity concentrations had a range from about 2 to approximately 50 pCi/g ash with the majority of values between 1 and 20 pCi/g ash. These concentrations are well within the range of PDAPS preoperational data. The corresponding values in terms of pCi/g original sample showed a similar range from a few hundredths to a few tenths of a pCi/g. As can be seen from the annual mean values shown in Figure IV. 8.1 there is no significant difference between station groups. 2339 104 PAGE 31

I I IV. DISCUSSION OF RESULTS Sr-89 was barely detected in one sample from Station 8 which is a remote location. I Cs-137 radioactivity was measured at concentrations from a few tenths to a few pCi/g ash. The corresponding average values were about 0.01 to 0.05 pCi/g original sample. As was the case in previous g years, wild vegetation tended to have values well above the overall 3 average. The annual mean values shown in Figure IV.8.2 indicate similar results at both groups of sample stations. There is no indication of a contribution to the radioactivity in vegetation from the operation of PDAPS as can readily be seen in Tables IV.8.3 and IV.8.4 and Figures IV. 8.1 and IV.O.2 comparing potentially affected stations with unaffected stations. Wide variabi-lity is to be expected between sample types because of differences in growing season and conditions. I. MILK The c onc en tra t ion s of gross beta, K-40, net beta, Sr-89, Sr-90, Cs-137, and I-131 radioactivity are given in Table IV.9.1, Mean values are presented in Table IV.9.2. Mean concentrations of Sr-90, Cs-137, and I-131 are plotted in Figures IV.9.1 through IV.9.3. For purposes of data comparison, farms have been divided into three groups: one containing Farms G, H, and J, which are regional farms near the Peach Bottom site; a second consisting of Farms A, D, C, and E, which encircle the Peach Bottom site at remote distancesi and a third consisting of Farms D, L, M, and N, which are at inter-mediate distances from the Peach Bottom site. The concentration of net beta radioactivity generally ranges from undetectable to a few hundred pC1/1 as has been the case during and g since the preoperational period. The major beta activity in milk is 3 due to the presence of naturally-occurring K-40 at concentrations of approximately 1100 pCi/1. The residual net beta values are most probably the result of the difference between two types of measure-ments and are not real. The gross beta radioactivity is measured directly on milk ash while the K-40 value is calculated from chemical measurement of potassium on dissolved ash. From the known metabolic process of cows, it is unlikely that any radioactive nuclides from a nuclear power plant other than those of strontium, cesium, barium-lanthanum, hydrogen or iodine would be present in milk. The Sr-90 ' radioactivity concentration for all farms was in the range of about 1 to 15 pCi/l with the majority of samples approxi-mately 5 pCi/1. This range is similar to or slightly lower than the ranges for 1975 through 1977. These concentrations are well within the range of PDAPS preoperational data. The quarterly mean values of Sr-90 for each farm group as shown tnr 9 ' )7 q 1UJ PAGE 32 ca e

IV. DISCUSSION OF RESULTS in Figure IV.9.1 generally lie between 4 and 9 pCi/1 and do not show any consistent difference between groups. The overall values are similar to those obtained during the PBAPS Units 2 and 3 preoperation-al period. St-89 was found in a few of the samples analyzed at levels up to 9 pCi/1. Most of the measurable values were obtained in samples taken in the first and second quarters and probably reflect fallout from 1977 and early 1978 atmospheric nuclear weapons testing. Values for Cs-137 radioactivity concentration range from about 2 to 15 pCi/1, similar to that seen in 1977. No significant difference was observed among the three farm groups as can be seen from Figure IV.9.2. The higher individual values tended to occur in samples taken during the second and third quarters. The results are similar to those measured during Units 2 and 3 preoperational period. I-131 radioactivity concentration results, corrected for decay to date of sampling, are presented in Table IV.9.1. I-131 was detectable in only one of the regularly scheduled samples. The May sample from Farm J had a value of 7+/.2 pCi/1. Data from another portion of the Peach Bottom environmental monitoring program indicated detectable values of I-131 in samples from all groups through most of May as a result of the March, 1978 atmospheric nuclear weapons test. None of the samples contained radioactivity which can be attri-buted to the operation of PBAPS. J. RADDITS Tables IV.10.1 through IV.10.4 present the analytical data and mean values obtained from the snalysis for gross beta, K-40, and net beta radioactivity concentrations in rabbit bone, soft tissue, and muscle, and Sr-89 and St-90 in bone. Iodine-131 concentrations in rabbit thyroids are also given. Guarterly mean values for net beta and Sr-90 radicartivity concentrations are shown in Figures IV.10.1 and IV.10.2. No rabbits could be obtained during the second half of 1978. An additional set of rabbits will be obtained during the first quarter of 1979 to fulfill the sampling and analysis requi-ements. Measureable net beta radioactivity concentration in muscle and soft tissue ranged from 20 to 50 pCi/g ash indicating again that the majority of the activity is due to K-40. Corresponding values are about a factor of 100 lower as pCi/g original sample. For bone, values ranged from about <10 to 20 pCi/g ash decreasing by a factor of 3-5 as pCi/g original sample. These values are consistent with the values seen during the PBAPS Units 2 and 3 preoperational period. Sr-90 radioactivity values in bone ranged from about 4 to 13 PAGE 33

I I IV. DISCUSSION OF RESULTS pCi/g ash similar to the range seen in 1977. The pCi/g original sample values are a factor of 2-5 lower. Sr-89 was detected in one rabbit bone. The value of 2.3 pCi/g ash was similar to those found in 1977 and is probably the result of fallout from atmospheric nuclear weapons testing. I-131 was barely measurable in three of the thyroids analyzed. This is probably the result of fallout from atmospheric nuclear l weapons testing. W There is no indication of radioactivity in rabbits which can be attributed to operation of PBAPS. 2539 107 l I I I I I I I I I I PAcg 34 8

SUMMARY

The environs radiation monitoring program detected plant related radioactivity at very low levels in two sample types in or near the discharge water system. Cs-134 was detected in silt at several loca-tions. 2n-65 was found in one fish from the onsite environment and slightly higher concentrations of Cs-137 were found in fish from some affected stations than unaffected stations. There was no other measurable environmental radioactivity which is attributed to the op era tion of PD APS. Several nuclides such as Sr-89, I-131, Zr-95, and Nb-95 were found in certain samples as a result of nuclear weapons testing by the Peoples Republic of China in September, 1976 and March, 1977. Another atmospheric nuclear weapons test in December, 1978 also by the Peoples Republic of China was not detected in this program or in any but a few locations in the nationwide ERAMS program operated by the Environment-al Protection Agency. Samples such as soil, fish, etc. showed gross and/or net activi-ties which are consistent with the known presence of naturally-occur-ring nuclides or which are most probably attributable to fallout from earlier nuclear testing and therefore did not result from PDAPS operation. 2ij9 108 PAGE 35
