I. INTRODUCTION A pre-operational environmental radioactivity survey, initiated 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 1 for decommissioning was on October 31, 1974. For the purposes of this monitoring program, the 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 reectors each with a power output of approximately 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 reached on June 16, 1974. The first fuel was loaded into Peec$ Dottom Unit 3 on July 5, 1974, criticality was achieved on Aug_,st 7, ,974, 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 ano sum-marizes the results of all analyses performed on samples collected from February 5, 1966 through August 8, 1973. Detailed program description, station designations, reporting units, abbreviations, etc., +re given in that report reflecting the program status at that time. Where changes had been made from the original program, they are indicated in the appropriate sections of that y2ar s report. In general, any such changes have been made to increase the scope and spccificity of the program to fulfill the program objective and to reflect the latest recommendations of various government agencies.

These changes are detailed in previous reports.

This report summarizes the results of analyses performed by Interex on samples representing the period January 1 through December 31, 1979 in the Interex portion of the overall Peach Dottom program.

The laboratory responsibility for performance of the environment-al radiation monitoring program has been modified several times since 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 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 the first quarter of 1969, the program was transferred to ICN/ Tracer-lab, also part of the International Chemical and Nuclear Corporation

, 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-ferred to Interex Corporation laboratories in Waltham. The Interex

I. INTRODUCTZON 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 concentrations 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 er.eted at the end of the report pe,iod is described below. Since 5. t u inception, several changes have been made

, to better accomplish the "rogram goals.

A. Environmental Monitoring Stations and Media Collected The environmental monitoring stations are described in Table II.1 and are shown in Figures I I .1 through II.3. In general, stations have not been moved significantly since the start of the program.

A new location designated Station 4J was added to replace Station 4C for silt sampling. The first sample from Station 4J was taken on May 3, 1979.

. Sampling and Analysis Program The types of analyses performed, the frequency of sampling and analysis, the locations of samples, and the number of an;1gses per station scheduled for each location as of the end of the report period, are given an Table II.2.

A summary of the analyses performed on samples representing January 1, 1979 through December 31, 1979 is given in Table II.3.

Several modifications were made in sampling and analysis during 1979.

These changes are as f ollows:

1. Sampling was discontinued at discharge water station I T.

2. Current analyses on soil are done semi-annually rather than quarterly. Gross alpha analysis are no longer done.

3. Silt sampling was terminated at Station 4C and initiated at Station 4J.

4. Radiochemical analysis of fish for Sr-89, Sr-90 and Cs-137 was eliminated from the basic program. Sr-89 and Sr-90 analyses

l IV. DISCUSSION OF RESULTS The results obtained from the program are presented in the data tables and figures following this section and are discussed below according to sample type. In this report, results 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-activity in food products, as determined by the radiation monitoring program, in terms of the sample state which is eaten by man. The results r,* ported in these units, however, offer poorer comperisons 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 comparison. 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 original sample weight.

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 ares 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 contains at least one real number is given as a real number. If all 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 stressed as are comparisons of results from stations which would most likely be affected by Peach Bottom Atomic Power Station (PBAPS) operation, with data from those which are more r eino t e 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.

A. AIR PARTICULATES The values of the concentrations of gross beta radioactivity observed in air particulate samples are listed in Tables I V. 1. 1 through IV.1.4 and are presented graphically in Figures I V. 1. 1 and I V.1. 2. Gamma spectral analyses are given in Table I V.1. 5.

For comparative purposes, stations have been divided into three groups. Group I, which is on the Peach Bottom site and closest to the PAGE 21

I V. DISCUSSION OF RESULTS density, i . e. , pCi/m2, is used in addition to concentration (pCi/1),

because it tends to minimize the effect of sample volume. Lack of complete. correlation with air particulate values comes about because rainfall generally does not occur at frequent intervals. The dependence of the activity levels on the precise conditions occurring at the start of each rainfall can cause wide variability between samples even when taken over limited geographical areas.

Similar to air particulate values, the gross beta radioactivity concentrations in samples collected at Stations 1A and IB were relatively constant throughout the year and were lower than found in 1978 when there was nuclear testing. Individual monthly results ranged from a few to 15 pCi/1 corresponding to a few hundred to 1800 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 similar to those from samples from Stations 1A and 1B except that they are generally slightly lower when compared as pCi/m3. This has been the case since 1974 and was seen in several years during the pre-operational period.

No Sr-89 radioactivity concentration was detected in any of the samples. This is consistent with the absence of fresh nuclear weapons test debris as evidenced by the air particulate data.

Sr-90 radioactivity concentrat.sns *oere generally measured to be a few tenths of a pCi/1. Surface densit: es were a few tens of pCi/m2. These levels are comparable to ar lower than what has been observed in previous periods.

Cs-137 radioactivity concentrations and surface densities at Stations 1 A, 1B, and CM as given in Tables IV.2.1 and IV.2.2 are generally less than 1.5 pCi/l or 100 pCi/m2.

The observed radio.sctivity concentrations at Station 1A, 1B, and 4M show the 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 in Tables IV.3.1 and IV.3.3. Similar values for the composite samples from Stations 1LL, 1 MM, 4L and 6I are given in Tables IV.3.2 and IV.3.4. Mean radioactivity concentra-tions are given in Tables IV.3.1 through IV.3.4. Comparative monthly and annual values are presented in Figures IV.3.1 through IV.3.6.

No measurable alpha radioactivity was found in the soluble fraction in any of the samples. The gross alpha radioactivity con-centrations in the insoluble fraction were generally a few tenths of a PAGE 23

I V. DISCUSSION OF RESULTS permeability of the soil and rock encountered by the water differs.

An additional factor which can enange 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 builoup of radioactivity concentration if conditions very close to the well are amenable to leaching, or it can cause concentrations to decrease if water from the major sources of the radioactivity does not reach the well when samples are taken.

Cross 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.

Approximately one quarter of the gross beta values were above the detection limit of 2 pCi/1. The measured values were in the range of 2 - 4 pCi/1.

Uranium was also detected in most of the samples from on-site ano off-site locations. The levels in general are similar to those seen in previous periods. Uranium is naturally-occurring in most rocks and is not of plant origin.

No St-89 or Cs-137 radioactivity was detected in any of the samples.

Very low concentrations of 57-90 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 possible to confirm the Y-90 decay so the concentrations may not be real.

Mean values as given in Table IV.4.1 show no significant dif,ferences between wells close to or on site and those at distant locations indicating no measured radioactivity from the operation of PBAPS.

E. SOIL The'results obtained for concentrations of acid-leachable gross beta, K-40, net beta, St-90, Sr-89, and Cs-137 radiosctivity in soil samples are given in Table I V. 5.1. Mean values for Sr-90, St-89, and Cs-137 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 thorium series and K-40, and from nuclides present in fallcut from atmospheric nuclear weapons testing. Specific analysis for Sr-89, Sr-90, and Cs-137 which are normally present in fallout are done to measure these nuclides in the presence of the larger quantities of naturally-occurring radioactivity.

Net beta radioactivity, which was detectable in all of the samples, was between 2 and 8 pCi/g dry weight. These values are with-in the range of normal variability.

P E 25

I V. DISCUSSION OF RESULTS few tenths of a pCi/g dry weight which is well within the range of PBAPS preoperational data. One sample from Station 4J had a value of

. 1.22 pCi/g dry weight. Any apparent discrepancy between the radio-chemistry values and gamma spectrum values most probably occurs 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, 4J. and 4T which are at increasing distances from the PBAPS discharge. There does not appear to be any consistent correlation of the observed levels with particular locations when normal variability is taken into account.

The preoperational data show approximately the sane spread in values and values of similar magnitude to those seen during this period.

The observance of Cs-134 at two of the locations is discussed below.

A comparison of Stations 1DD, 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 positive addition of radio-activity by PBAPS operation, when normal variability is taken into account.

Gamma spectrum analysis showed primarily the presence of K-40 and the U. Th series as represented by Ra-226 and Th-228 respective-ly, all of which are naturally-occurrinD and Cs-137. Cs-134 was found in some samples from Stations 4J and 4T and is most like}y from PBAPS operation because it is a reactor generated product.

The overall similarity of results between locations and with the preoperational data indicates no addition of radioactivity due to the operation of PBAPS except for very srall concentrations of Cs-134 and Cs-137. If it is assumed that all cesium found is due to PBAPS releases, a dose calculation using the USNRC Regulatory Guide 1.109 model and assumptions results in a calculated dose of 9.16 E-3 mrem to a teenager's skin. This calculation conservatively assumes that the teenager was exposed to the maximum concentration found for the entire exposure period.

G. FISH The results of the analysis of fish samples for concentrations of gross beta, K-40, net beta. Sr-89 and Sr-90 radioactivity are given in Tables IV.7.1 and IV.7.2. Gamma spectrum data are presented in Table IV.7.3. Mean values are presented in Tables IV.7.1, IV.7.2, IV 7.4, and IV.7.5. Sr-90 concentrations are plotted in Figure IV 7.1.

Net beta radioactivity generally ranged from <10 to 80 pCi/g ash with the majority of the results below 20 pCi/g ash. The values were well within the range of PBAPS preoperational data.

Radiostrontium analysis was resumed on a temporary basis during l the second half of 1979 because of the possibility of release of Sr-89 l PAGE 27

T V. DISCUSS 10N OF RESULTS 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 pC1/g. As can be seen from the annual mean values shown in Figure I V. 8. 1 there is no significant difference between station groups.

St-89 was barely detected in three samples. The considerations discussed previously also apply here.

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 years, wild vegetation tended to have values above the overall 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 I V. 8.1 and IV.8.2 and Figures I V. 8. 1 and IV.8.2 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 concentrations of gross beta, K-40, net beta, St-89, St-90, Cs-137, and 1-131 radioactivity are given in Table I V. 9.1. Mean values are presented in Tables IV.9.1 and IV.9.2. Mean concentrations of St-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, B, C, and E, which encircle the Peach Bottom site at remote distances; 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 pCi/1 as has been the case during and since the preoperational period. The major beta a c '. i v i t y in milk is 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 3 to 12 pCi/1 with the majority of samples approx 1-mately S pCi /1. This range is similar to or slightly lower than the PAGE 29 )

I V. DISCUSSION OF RESULTS orig s1 sample values are a factor of 3-6 lower.

.+-89 was possibly detected in a few rabbit bones. The considerations discussed earlier apply to t h e's e results also.

A small amount of I-131 was measurable in three of the thyroids analyzed. The maximum value was 9+/-5 pCi per thyroid. This may be attributed to PBAPS operation since I-131 activity was found in milk around the same time in another portion of the monitoring program.

Other than the I-131 activity, there it no indication of radioactivity in rabbits which can be attibuted to operation of PBAPS.

V.

SUMMARY

The environs radiation monitoring program detected plant related radioactivity at very low levels in two sample types in Conowingo Pond and in or near the discharge water system. Cs-137, Cs-134, and Zn-65 were found in fish samples obtained from 4 locations in the last half of the year. Silt samples at 2 locations showed Cs-137 and Cs-134. The resulting doses to the maximum exposed individual were well below 10 CFR 50 Appendix I design ob Jectives. .

As indicated by the radioactivity concentrations measured in air particulate and precipitation samples, fallout from previous nuclear testing has decreased to levels seen before testing resumed in fall of 1976.

Samples such as-soil, fish, et . showed gross and/or net activities which are consistent with the known presence of naturally-occurring nuclides or which are most probably attributable to fallout from earlier nuclear testing and therefore did not result from PBAPS operation.

There was no other measurable environmental radioactivity which is attributed to the operation of PBAPS.
