SUMMARY

AND CONCLUSIONS This report on the radiological environmental monitoring program con-ducted at the Peach Bottom Atomic Power Station for Philadelphia Electric Company by Radiation Management Corporation covers the period January 1, 1982 to December 31, 1982. During this period 4613 analy-ses were performed on 3971 samples.

Surface water and discharge water samples were analyzed for concentra-tions of tritium, gross beta, and gamma-emitting nuclIdes. Surface water was also analyzed for concentrations of gross alpha. Compari-sons of unaf fected stations with potentially af fected stations, in Conowingo Pond, showed no significant difference in concentrations of the radionuclides studied. It was shown that no significant differ-ences existed between the preoperational and operational periods; therefore, it ca1 be concluded that the levels of radioactivity in Conowingo Pond wster have not been measurably influenced by the operation of the Peach Bottom Atomic Power Station.

High sensitivity .-131 analyses wsre performed on weekly air samples.

All results were is:s than the minimum detectable level.

High sensitivity 1-13' analyses were also performed on weekly milk samples while cows were on pasture and on monthly samples when cows were not grazing. All results were less than the minimum detectable level.

Soll samples were analyzed for concentrations of Sr-89, Sr-90 and gamma-emitting nuclides and levels observed were not significantly different from preoperational data.

Environmental gamma radiation measurements were made using thermolumi-nescent dosimeters. Results from the site-boundary, middle and outer l

rings were found to be not significantly different, so it can be con-cluded that the operation of Peach Bottom Atomic Power Station did not

( produce measurable levels of ambient gamma radiation at any of f-site location.

In assessing alI the data gathered for this report and comparing the results with preoperational data, it was evident that the operution of the Peach Bottom Atomic Power Station resulted in no significant radiological impact on the environment.

f II. INTRODUCTION Radiation Management Corporation (kMC) began conducting a radiologi-cal environmental monitoring program in September 1970 for the Phila-delphia Electric Company in connection with the Peach Bottom Atomic Power Station (PBAPS) located in Peach Bottom Township, York County, Pennsylvania. This RMC program complements an existing program being conducted by others which has been carried out since March 1%0.

PBAPS is located along the Susquehanna River between Holtwood and Conowingo Dams. The fourteen mile long pond created by Conowingo Dam is called Conowingo Pond.

The initial loading of fuel into Peach Bottom Unit #1, a 40 MWe (Net) 1 high temperature gas-cooled reactor, was started on February 5,1%6, and initial criticality was achieved March 3, 1966. Final shutdown of Peach Bottom Unit #1 was on October 31, 1974. Peach Bottom Unit #2 and #3 are boiling water reactors each with a power output of approxi-mately 1050 MWe (Net). The first fuel was loaded into Unit #2 on August 9,1973, and criticality was first achieved on September 16, 1973. The fuel was loaded into Unit #3 on July 5, 1974 and criticali-ty was first achieved on August 7, 1974. Peach Bottom Unit #2 first reached full power on June 16, 1974. Peach Eottom Unit #3 first reached fulI power on December 21, 1974.

Results of the RMC portion of the overall regional radiological environmental monitoring program have been reported in semi-annual reports. Semi-annual reports were discontinued af ter 1975. This report contains data for samples representing the period January 1, 1982 through December 31, 1982.

A special preoperational report (1) for Peach Bottom Units #2 and #3

.' has been issued previously which summarizes results of all analyses

( performed by RMC on samples collected from the start of the RMC por-tion of the overall program through August 8, 1973, the day before r fuel was first loaded into Peach Bottom Unit #2.

A. PROGRAM OBJECTIVES

[ 1. Identify, measure, and evaluate existing radionuclides in the environs of the Peach Bottom Site and any fluctuations in radioactivity levels which may occur.

2. Monitor and evaluate ambient radiation levels.

3. Determine, within the scope of the program, any measurable quan-tity of radioactivity introduced to the environment by the opera-tion of the Peach Bottom Atomic Power Station.

4. Complement other existing radiological environmental monitoring programs at Peach Bottom Atomic Power Station, t

3 f

B. PROGRAM IMPLEMENTATION in order to achieve these objectives, Radiation Management Corporation performed the following analyses on samples collected during the period of this report.

A. SAMPLE COLLECTION AND TLD PLACEMENT PROCEDURES The program being conducted by RMC is described in Tables I and iI and Figures 1-3.

1. Sample Collection

a. Water (except precipitation)

All samples were collected in new polyethylene bottles. All

) persons involved in sample collection and handling were ad-vised not to wear tritium luminous dial watches in order to avoid possible cross contamination from that source. Sample containers were rinsed at laast twice with the water to be sampled before collection.

All water samples were grab samples except those collected at stations ILL, IMM, 61 and 4L. Weekly samples were taken from a tank which continually collects a sample at these four locations. The weekly samples were composited into a monthly samplo for analysis. Collection methods are de-scribed in more detail in Table 11,Section V.

I

b. Precipitation Precipitation was collected in ar. apperatus consisting of a new polyethylene bottle with a plastic funnel 8 inches in e diameter. The bottle was replaced monthly and the sample l

bottle was shipped to RMC for analysis. The amount of pre-cipitation was recorded continuously by a separate rain gauge at station IA.

c. Air Particulates f Air particulate samples were obtained using a vacuum sampler H and glass fiber filters, approximately 2" in diameter. The filter was replaced weekly and sent to RMC for analysis.

r The vacuum sampler was run continuously at approximately 1 l cubic foot per minute.

d. Air lodine 1

Air Iodine samples were obtained using a vacuum sampler and charcoal filters, approximately 2" in diameter. The filter was replaced weekly and sent to RMC for analysis. Tha vacuum sampler was run continuously at approximately I cubic foot per minute.

F

e. Milk Milk samples were coilected in new polyethylene bottle from the bulk tank at each farm, refrigerated and shipped immedi-ately. No preservative was added.

5 P

f. Soll Soll samples consisting of seven cores, 2" in diameter and 6" deep were collected f rom a 50 X 50 f t. area at each sam-pling location. Top soll (upper 1 inch) and bottom soll (lower 5 inches) were separated, then sealed in separate plastic bags, and shipped to RMC.

2. TLD Placement A system using thermoluminescent dosimeters (TLDs) was used to measure the direct radiation levels in the PBAPS environment.

The TLD stations were placed on and around the Peach Bottom Site using the "three ring concept". Two on-site stations, designated as plant omnplex stations are not included in any of the three rings.

a. A site boundary ring near and within the site perimeter, representing fencepost doses, i.e., at locations where the doses are greater than maxitnum annual off-site doses from Station releases;

b. A middle ring extending to approximately 10 miles from the Site, designed to measure possible exposures to close-in l population;

c. An outer ring extending f rom approximately 10 to about 60 miles from the Site; and considered not to be affected by Station releases;

d. The specific location of each station was determined by the following criteria:

(1) The presence of relatively densely populated areas; (2) From Site meteorological data taking into account distance and elevation for each of the 36 ten-degree sectors around the Site, where estimated annual dose from the Station, if any, would be more significant; (3) On hills and (where practical) within sight of the stack, and free from local obstructions; (4) Near the closest house to the stack in the prevailing down-wind direction,

e. Each TLD set (4 TLDs por set) was placed in a sealed poly-ethylene package to verify the integrity of the dosimeters when collected. Two packages were kept in a locked formica

" birdhouse" or polyethylene jar, about six feet above the ground or supporting surface at each location. At each station one package was exchanged for measurement on a monthly schedule, and one on a quarterly schedule.

None C. ANALYSES PERFORMED The schedule of analyses performed by RMC is listed by sample g type in Table 11. This schedule was followed except where noted 1 below. Table lll lists the type and number of analyses performed during this period by sample type and station location. Methods used in performing these analyses can be found in Section Vil of L this report.

D. EXCEPTIONS TO THE PROGRAM q 1. Discharge water samples were not collected from station IMM from 1/08/82 to 1/15/82 and 5/21/82 to 5/28/82 due to pump malf unc-tions.

2. 1-131 data were not available for surface water samples collected f rom stations 4L and 61 f rom 11/27/82 to 12/04/82 due to a computer malfunction.

3. TLD data were unavailable from station 46 for October,1982 due to vandalism.

4. Milk sample from station A collected 6/28/82 was unavailable for analysis due to shipping loss.

IV. RESULTS AND DISCUSSION f

A. DATA INTERPRETATION AND STATISTICAL ANALYSIS Several factors are important in the interpretation of the data.

In order to avoid undue repetition in the discussion which fol-lows, these factors are described below.

1. Grab SampiIng Grab sampling is a useful and acceptable procedure for

( taking environmental samples of a medium in which the con-centration of radionuclides is expected to vary slowly with time or where intermittent sampling is deemed sufficient to

{ establish the radiological characteristics of the medium.

This method, however, is only representative of the sampled

[ medium for that specific location and instant of time. As L. a result, variation in the radionuclide concentrations of the samples wilI normally occur. Since these variations will tend to counterbalance one another, the extraction of averages based upon repetitive grab samples is va!Id.

2. Minimum Detectable Levels (MDL)

It is characteristic of environmental monitoring data that many results occur at or below the specified detection level. Formal statistical error analysis of groups of such data is difficult. Pragmatic approaches to the problem in-clude counting the detection level entries as zero, as half the detection level value, or as full detection level value.

For reporting and calculation of averages in this report, any result occurring.at or below the minimum detectable level is considered to be at that level. Averages obtained

( using this method are therefore biased high.

3. Standard Deviation of Analytical Results E Within the data tables an approximate 95% (2 sigma) confi-dence interval is supplled for those data points at and

[ above the minimum detectable level. These Intervals repre-L sent the range of values into which 95% of repeated counts of the prepared sample would fall.

I 4. Table Means and Standard Deviations Results for each type of sample were grouped according to the analysis performed. Means and standard deviations of these results were calculated. These standard deviations represent the variability of measured results for different I samples rather than single analysis uncertainty. For these calculations, all results below the MDL were considered to be at the MDL. As a result, the means are biased high, and d

the standard deviations are biased low.

t

B. DISCUSSION OF RESULTS Results are summarized in brief form in Tables IV, V and VI (Section V). Tablos of results for individual sample types and analyses performed can be found in Section V, Tables Vil to XXVI. Graphical presentations of results can be found I.

Section VI.

1. Surface Water Samples were taken from eight stations on a monthly sche-dule. Three stations (ILL, 4L and 61) were continuous com-posite samples and f ive (1Q, 4F, 4G, 6A and 13A) were grab i samples. Station 13B was sampled a total of eight times in 1982. Of these stations, seven could be af fected by re-leases from Peach Bottom Atomic Power Station. The re-maining stations (6A and 61) were above Holtwood Dam and, therefore, could not be af fected by plant discharges (re-fer to Figures 1 and 2,Section VI, for station locations).

The fol lowing analyses were performed on surf ace water sam-ples.

a. Tritium Total samples from seven stations were analyzed for con-centrations of aqueous tritium. Samples from stations ILL, 1Q, 4L and 61 were analyzed on a monthly basis, while ]

samples from stations 4F, 6A and 13A were composited >

monthly into a quarterly sample. Results of this analysis for surf ace water samples can be found in Tables Vil and Vill,Section V. The concentrations detected were within the range found during the Peach Bottom Units #2 and #3 preoperational period (1). Graphical comparisons of the unaf fected stations (6A and 61) above Holtwood Dam with potentially affected stations (4F and 4L) at Cono-wingo Dam showed no detectable addition of tritium to '

Conowingo Pond from the operation of PBAPS (Figures 4 and 5,Section VI).

b. Gross Alpha Samples f rom four stations (4F, 4L, 6A and 61) were analyzed for gross alpha concentrations in tho soluble and insoluble fractions. Results of gross alpha anal-ysis in surface water samples can be found in TaDles Vil and Vill,Section V. Results at all locations were generally at or below tha minimum detectable level in the soluble fraction. Results of the insoluble fraction Indicated a small amount of activity present.

Most activity levels found were within the range of the MDL values observed.

r 10

f c. Gross Beta Samples from all stations, were analyzed for concentrations of gross beta in the soluble and insoluble fractions. Re-suits of gross beta analysis in surface water samples can be found in Tables Vll and Vlli,Section V. The concentra-tions detected in the soluble fraction were within the range observed during the preoperational period for Units #2 and and #3 (1). Detectable activities were observed in the in-soluble fraction of surface water. The activities observed f were within the range of the MDL values. A graphical comparison of two Conowingo Dam stations (4F and 4G) with one Holtwood Dam station (6A) showed the results of the

( soluble and insoluble fractions to be generally the same for all three locations (Figures 6 and 7,Section VI).

d. iodine-131

{

Samples collected during the last week of each month from 1/09/82 to 12/04/82 from two stations (4L and 61) were anal-

yzed for concentrations of I-131. Results of I-131 analysis of surf ace water samples can be found in Table Vill,Section V. Most results were below the minimum detectable level.

f Detectable concentrations were found at station 4L in Febru-ary, and at station 61 in March. The 1-131 activity was attributed to upstream sources.

e. Gamma Spectrometry r Samples from alI stations were analyzed for gamma-emitting

( nuclides by gamma spectrometry. Results of gamma spectro-metry on surface water samples can be found in Table IX, e Section V. The nuclides searched for were below the mini-L mum detectable level with the exception of K-40 which was found at two stations, 61 and 138.

2. Discharge Water Sanples were taken from two stations (IM and IMM) on a monthly schedule (refer to Figure 1,Section VI, for L

station locations). The following analyses were performed on discharge water samples.

a. Tritium Total samples from both stations were analyzed for concen-( trations of aqueous tritium on a monthly basis. Results of tritium analysis in discharge water samples can be found in

, Table X and XI,Section V. The concentrations detected s

11

were within the range found during the Peach Bottom Units

2 and #3 preoperational period (1). A graphical compari-son of concentrations of aqueous tritium results for com-posite surface water and discharge water samples showed no significant differences (Figure 8, Sectin VI).

b. Gross Beta Monthly samples from both stations were analyzed for gross beta concentrations in the soluble and insoluble fractions.

Results of these analyses in discharge water samples can be found in Tables X and X:,Section V. The concentrations detected in the soluble and insoluble fractions were simi-lar to those observed in surface water samples (Figures 9 and 10,Section VI).

c. Gamma Spectromotry Samples from both stations were analyzed for gamma-emitting nuclides by spectrometry. Results of gamma spectrometric analysis are given in Table XI1,Section V. AlI nuclIdes were less than the minimum detectable level.

3. Well Water Samples were taken from four stations on a quarterly sche-dule. Two stations (1U and IV) were located within the Site area. The other stations were located approximately one mile (station 40) and 10 miles (station 7) from the Plant. These station locations are shown in Figures 1 and 2,Section VI. The following analyscs were performed on welI water samples.

a. Tritium Total samples from ai! four stations were analyzed for aqueous tritium concentrations. Results of tritium anal-ysis of well water samples can be found in Table Xill,Section V. Results of all samples were within the range found during the Peach Bottom Units #2 and #3 preopera-tional period (1). A graphical comparison of the distant site-area, and on-site wells showed that tritium le is have been gradually decreasing with time due to the a sa-tion of routine atmospheric nuclear weapons testing (Figure 11,Section VI).

b. Gross Beta Samples from all four stations were analyzed for gross beta concentrations in the soluble and insoluble fractions. Re-suits of gross beta analysis on well water samples can be found in Table Xill,Section V. The concentrations detec-ted in the soluble fraction were within the range observed 12

l during the Peach Bottom Units #2 and #3 preoperational period (1). Concentrations detected in the insoluble frac-tion were similar to data observed for surface and discharge water.

4. Precipitation 4

Precipitation was collected f rom two stations on a monthly schedule. Station IA is located at the on-site Peach Bottom Weather Station #1. Station 8, located in Colora, f MD., is approximately 10 miles from the Site (for station locations, refer to Figures 1 and 2,Section VI). The fol-lowing analyses were performed on precipitation samples.

a. Gross Beta Monthly samples were analyzed for gross beta concentrations

{ in the total sample. Results of gross beta analysis in precipitation samples can be found in Table XIV,Section V.

Concentrations detected were within the range found during

(.

the Peach Bottom Units #2 and #3 preoperational period (1).

b. Gamma Spectrometry Monthly samples were analyzed for gamma-emitting nuct ides by spectrometry of the total sample. Results of gamma spec-trometric analysis of samples from both stations are given

{ in Table XV,Section V. Be-7 was found in two of twenty-four samples and can be attributed to cosmic ray activity.

5. Air Particulates Continuous air particulate samples were collected from the r

( on-site Peach Bottom Weather Station #1 (1Z) and from the intermediate location, Conowingo Dam (4A) (For station locations, see Figure 1 and 2, section VI). The following analyses were performed on air particulate samples,

a. Gross Beta Weekly samples were analyzed for concentrations of beta emmitters. Results of gross bete analysis of air particu-(

late samples can be found in Table XVI,Section V. Results

( observed were similiar to levels observed in previous years.

b. Gamma Spectrometry Monthly composite samples were analy:cd for gamma-emitting nuclides by gamma spectrometry. Results of gamma spectro-metric analysis are given in Table XVil,Section V. Be-7 was detected in 22 of 24 samples and was the result of cosmic ray activity. Naturally occuring K-40 was found in 5 of 24 samples. Co-60 was found at the on-site station 1Z in July

with an activity of 611 pCI/m3. Confirmation was made by recount analysis.

6. Air lodine Continuous air samples were collected at eight stations and analyzed weekly for 1-131. Three stations (18,1Z, 2) were located within the Site area. Four stations (3A, 5, 6B, 14) were located at Intermediate distances of 1.9 to 5.8 miles from the site. One station (12D) was located 62 miles from the Site. Results of I-131 analysis can be found in Table XVill,Section V. All results of the 416 analyses performed were less than the minimum detectable level.

7. Milk Milk was sampled at eleven f arms; three f arms (G, J and 0) located within two miles of PBAPS were designated "near farms"; four farms (D, L, M and N) located 3 to 5 miles from PBAPS were designated as " Intermediate farms"; and four farms (A, B, C and E) located greater than five miles from PBAPS were designated as " distant f arms". The following analyses were performed on milk samples.

a. Tritium Milk from four farms (A, C, G and J) was analyzed for tri-tium concentrations in the aqueous fraction on a quarterly basis. Results of tritium determinations in milk samples s

can be found in Table XIX,Section V. Concentrations de-tected were within the range found during the Peach Bottom Units #2 and #3 preoperational period (1).

b. lodine-131 Milk from eight farms (A, B, C, D, G, J, N and 0) near Peach Bottom was analyzed for concentrations of I-131, monthly in January, February, March and December. Weekly 1-131 analy-ses resumed during the last week of March and continued 14

. - _ _ _ _ _ _ _ _ _ - _ _ l

f through the fourth week of November. Three additional farms (L, M and E) were sampled and analyzed quarterly for 1-131.

Results of I-131 analysis can be found in Tables XIX and XX,

( Section V and Figure 12,Section VI. All results were less I than the minimum detectable level.

c. Strontium-89 and Strontium-90 One milk sample was collected at farm J in each quarter and analyzed for Sr-89 and Sr-90. Results can be found in Table XXI,Section V. Except for the third quarter which had a f result of 6+3 pCi/l, Sr-89 results were less than the minimum detectable level. Sr-90 concentrations were similar to those observed in previous years.

{

d. Gamma Spectrometry One milk sample collected at f arra J in each quarter was analyzed for gamma-emitting nuct ides by gamma spectrometry.

Results can be found in Table XXI,Section V. Nuclides de-( tected were naturally occurrng K-40 and Cs-137. Cesium-137 is commonly found in rallk as a result of world-wide f allout.

8. Soll

(

Semiannual samples were taken at three locations, one on-site station (2) and two distant stations (3A and 5) located

{ about four miles from PBAPS (for station locations, see Figures 1 and 2,Section VI). The area at station 2 is heavily wooded with rock outcroppings. The soll at this location would be expected to contain substantial humus from the accumulation of natural vegetative debris. Station 3A is covered only with grass. Station 5 is a combination of

( grass and cultivated land. The following analyses were per-formed on soll samples.

a. Strontium-89 and Strontium-90

Samples from alI stations were analyzed for Sr-89 and Sr-90 concentrations in the top one inch and bottom five inches

[ separately. Results of Sr-89 and Sr-90 analysis in soll samples can be found in Table XXil,Section V. Concentr a-tions of Sr-89 were less than the minimum detectable

, level in all samples. Concentrations of Sr-90 detected were within the range found during the PBAPS Units #2 and #3 pre-operational period (1). Graphical comparisons of Sr-90 in

( the top one Inch and bottom cut can be found in Figures 13 and 14,Section VI. Dif ferences between the on-site location (2) and distant locations (3A and 5) were attributed to the accumulation of vegetative debris at station 2.

b. Gamma Spectrometry l

Samples from all stations were analyzed for gamma-emitting l nuclides oy Ge(LI) gamma spectrometry (Table XXil,Section V). Nuclides identified were generally the same as those -

found during the PBAPS Units #2 and #3 preoperational period with most at the same or lower concentrations (1). Some naturally-occurring nucIldes were found (K-40, Ra-226, Th-232). Small concentrations of Cs-137 were detected in (

all twelve samples and were similiar to levels observed in 1 l previous years. The 30 year half-life and biological assimilation of Cs-137 accounts for the continued appearance of this nuclide in soll samples many years after atmospheric testing of nuclear weapons. Dif ferences between the on-site

location (2) and distant locations (3A and 5) were attribu-ted to the accumulation of vegetative debris at station 2 (Figures 15 and 16,Section VI). Sb-125, a Plant produced nuclide, was observed at the detection level at the on-site station 2.

9. Ambient Gamma Radiation Ambient gamma radiation levels were measured with calcium sulfate: Tm thermoluminescent dosimeters.

l Thirteen stations (1B,10,1D, IE,1F,1G,1H, IJ, IL, IM, 1NN, 2 and 40) were located around the Sito boundary and designated for comparison purposes as the " sit'e boundary ring". Twenty-five stations (3A, 4K, 5, 6B, 14, 15, 17, 22, 23, 26, 27, 31, 32, 33A, 38, 42, 43, 44, 45, 46, 47, 48, 49, 50 and 51) were located within u 10 mile radius of the Site and designated as the " middle ring". Seven sta-tions (12B,16,18,19, 20, 21B and 24) were located f rom 10 to 60 miles from the Site and designated as the " outer ring". Since they could be more directly affected by Plant activities and do not represent doses to the public, t A stations (1A and 11) located within the plant complex con-stitute a fourth group called plant-complex stations (fcr station locations, see Figures 1, 2 and 3,Section VI).

Results of TLD measurements are Iisted in Tables XXII 1, XXIV and XXV,Section V. The annual average of monthly and quarterly radiation levels were within the range found during the Peach Bottom Units #2 and #3 prooperational period (1). Graphical comparisons of the site-boundary, middle and outer rings on monthly and quarterly readings showed no sign-Ificant differences in ambient radiation levels with distance from PBAPS, Indicating no measurabla Station contribution (Table XXV,Section V, Figures 17 and 18,Section VI).
