I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Peach Bottom Atomic Power Station (PBAPS) by Exelon Nuclear covers the period 1 January 2001 through 31 December 2001. During that time period, 1101 analyses were performed on 968 samples.

Surface water samples were analyzed for concentrations of tritium and gamma emitting nuclides. No fission or activation products were found. Tritium levels were consistent with those observed in previous years and lower than levels seen during the preoperational years.

Drinking water samples were analyzed for concentrations of gross beta (soluble and insoluble fractions),

tritium, and gamma emitting nuclides. No fission or activation products were found. Gross beta and tritium activities detected were consistent with those observed in previous years.

The remaining sample media representing the aquatic environment included fish and sediment samples.

These media were analyzed for concentrations of gamma emitting nuclides. Fish samples showed no detectable fission or activation products from the operation of PBAPS. Cesium-137 activity was found at all sediment locations and was consistent with data from previous years. No other fission or activation products were found. The dose to a teenager's skin from the sediment pathway was calculated to be 5.93 E-04 mrem, which represents 0.003% of the allowable fraction of 10 CFR 50, Appendix I limits.

The atmospheric environment was divided into two parts for examination: airborne and terrestrial.

Sample media for determining airborne effects included air particulates and air iodine samples.

Analyses performed on air particulate samples included gross beta and gamma spectrometry. No fission or activation products were found. The gross beta results were consistent with results from the previous years. Furthermore, no notable differences between control and indicator locations were observed. These findings indicate no measurable effects from the operation of PBAPS.

High sensitivity Iodine-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity.

Examination of the terrestrial environment was accomplished by analyzing milk samples for low level concentrations of Iodine-1 31 and gamma emitting nuclides. No fission or activation products were found.

Ambient gamma radiation levels were measured quarterly throughout the year. All measurements were below 10 mR/standard month and except for the fourth quarter, results were consistent with those measured in previous years. The fourth quarter results were about 1 mR to 2 mR higher than results observed in the other quarters. The results were consistent at all stations indicating a non Peach Bottom induced effect.

The results of the TLD monitoring program were used to determine if the Independent Spent Fuel Storage Installation (ISFS[) had any measurable impact on the dose rate in the environs. Ecept for the fourth quarter data discussed above, no increase in dose was evident.

In assessing all the data gathered for this report and comparing these results with preoperational data, it was evident that the operation of PBAPS had no adverse radiological impact on the environment.

Intentionally Left Blank II. Introduction Peach Bottom Atomic Power Station (PBAPS) is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Township, York County, Pennsylvania. The initial loading of fuel into Unit 1, a 40 MWe (net) high temperature, gas-cooled reactor, began on 5 February 1966, and initial criticality was achieved on 3 March 1966. Shutdown of Peach Bottom Unit 1 for decommissioning was on 31 October 1974. For the purposes of the monitoring program, the beginning of the operational period for Unit 1 was considered to be 5 February 1966. A summary of the Unit 1 preoperational monitoring program was presented in a previous report (1). PBAPS Units 2 and 3 are boiling water reactors, each with a power output of approximately 1159 MWe. The first fuel was loaded into Peach Bottom Unit 2 on 9 August 1973. Criticality was achieved on 16 September 1973, and full power was reached on 16 June 1974. The first fuel was loaded into Peach Bottom Unit 3 on 5 July 1974. Criticality was achieved on 7 August 1974, and full power was first reached on 21 December 1974. Preoperational summary reports (2)(3) for Units 2 and 3 have been previously issued and summarize the results of all analyses performed on samples collected from 5 February 1966 through 8 August 1973.

A. Objectives The objectives of the REMP are:

1. To identify, measure, and evaluate existing radionuclides in the environs of PBAPS site and any fluctuations in radioactivity levels, which may occur.

2. To monitor and evaluate ambient radiation levels

3. To determine within the scope of the program, any measurable quantity of radioactivity introduced to the environment by the operation of PBAPS.

B. Implementation of the Objectives Implementation of the objectives is accomplished by:

1. Identifying significant exposure pathways.

2. Establishing baseline radiological data of media within those pathways.

3. Continuously monitoring those media before and during plant operation to assess plant effects (ifany) on man and the environment.

Ill. Program Description A. Sample Collection Samples for the PBAPS REMP were collected by Normandeau Associates, RMC Environmental Services Division (RMC). This section describes the general collection methods used by RMC to obtain environmental samples for the PBAPS REMP in 2001. Sample locations and descriptions can be found in Table B-1 and Figures B-i through B-3, Appendix B.

The collection procedures used by RMC are listed in Table B-2, Appendix B.

Aquatic Fnvironment The aquatic environment was examined by analyzing samples of surface water, drinking water, fish, and sediment. Surface water from two locations. (1ILL and 1 MM) arid drinking water from two locations (4L and 61) were collected weekly by automatic sampling equipment. Weekly samples from each of the surface and drinking water locations were composited into a separate monthly sample for analysis. Approimately, two quadts of water were removed from the weekly sample container and placed into a clean two-gallon polyethylene bottle to form a monthly composite. Control locations were 1LL and 61.

Fish samples comprising the flesh from two groups: Bottom Feeder (catfish) and Predator (smallmouth bass, largemouth bass, or bass) were collected semiannually from two locations: 4 and 6 (control) using several methods such as trapnet, seine or electroshocking.

Sediment samples composed of recently deposited substrate were collected semiannually at three locations: 4J, 4T and 6F (control) using one of two methods, determined by the depth from which the sediment was obtained. In water greater than 4 feet deep, either a Ponar or Ekman Grab was used to collect sediment. In shallow water (1-4 feet), sediment was collected by scooping up mud with a plastic bucket.

The atmospheric, environment was examined by anaryz~ing airbomrre and terrestrial samples.

These consisted of air particulates, airborne iodine, and milk. Air-particulate and air iodine samples were collected and analyzed weekly from five locations (1B, 1Z, I C, 3A, and 5H2). The control location was 5H2; Air samples were obtained us*ig a vacuum sampler, glass fiber and charcoal filters, respectively. The filters were replaced weekly and sent to the laboratory for analysis. The vacuum samplerswere run continuously at approinately 1 cubic foot per minute.

Milk samples were collected from fve locations (A, J, R and S) monthly from December through March and biweekly April' through Novembe*. Additionally, samples from seven locations (B, C, D, E, L, and P) were collected quarterly. Locations.A, B, C, and E were controls.

Milk samples were obtained by. removing two gallons from the dairyman's bulk tank after mixng. The sample from each location was therefore a composite of all the milk collected from the dairy herd (from 1 to 3 milkings). The milk was scooped from the agitated bulk tank and placed in new plastic containers.

Ambient Gamma Radiation Direct radiation measurements- were made using Panasornic 814 calcium sulfate (CaSO4) thermoluminescent dosimeters (TLD). The TLD locations were placed on and around the PBAPS site as follows:

A siteboundarying consisting of eighteen locations (1L, 1P, 1A, 1Q, 1D, 2, IM, 1R, 11, 1C, 1J, 1F,,40, 1NN, 11-t, 1G,. IB, .qnd IE) near and within the site, perimeter representing fence. post doses (i.e;, at locations where the, doses will be potentially greater than m*n*num annual off.-site doses) from PBAPS releases, An ijffta diata_ ne.i consisting of nineteen locatior-s (15, 22, 44, 32, 45, 14, 17, 31A, 4K, 23, 27, 48, 3A, 49, 50, 51, 26, 6B, and 42) exiending to approximately 5 miles from the site designed to measure possible exposures to close..-O population.

The balance of nine locations (2B, 43, 5, 16, 24, 46, 47, 18, and 19) representing control and special interests areas such as population centers, schools, etc.

The specific TLD locations were determined by the following criteria:

1. The presence cfrelatively dense population;

2. 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 PBAPS, if any, "wouldbe more significant;

3. On hills free from local obstructions and within sight of the vents (where practical);

4. Near the dwelling closest to the main stack in the prevailing down wind direction.

A TLD set was placed at each location in a Formica "birdhouse" or polyethylene jar located approamately six feet above ground level. The TLD sets were exchanged quarterly, then sent "tothe laboratory for analysis.

B. Sample Analysis This section describes the general analytical methodologies used by.Environmental Inc. and Teledyne Brown Engineering to analyze the environmental samples for radioactivity for the PBAPS REMP. in 2001. The nalytical procedures used by the laboratories are listed Table B-3, AppendixB.

The current program includes the following analyses:

1. -Concentrations. of,beta emitters in drinking water and air particulates.

.2. Concentrations .of gamma emitting nuclides in surface and drinking water, air particulates, nilk, fisl, and sdiment.

-,3. Concentrations oftritium in surface and'drinking water. .

Cpncentrai6n~s o 1V131 jn air and milk.

- 5. Ambient gamma radiatiowrevels at various site environs. .

C. Data Interpretation Several factors are-important in the interpretation of the data. These factors are discussed here to avoid ;undue repetition in the discussionmof thezresults.÷

1. Lower Limit of Detection and Minimum Detectable Activity The, ower. limit of detection.(LI-) was defined as the smallest concentration of

...radioactive

.. rnateriaLin a-sample that would yield a net count (above background) that would be detected with only.a 5% probability of falsely concluding that a blank observation represents a "real" signal. The LLD was intended as a before the fact Zestktateof a system (including~instrumentation, procedure and sample type) and

-notas-anafter Tefact criteria for the presence of actMty. All analyses were designed to achieve the required PBAPS detection capabilities for environmental sample analysis.

-11 -

The minimum detectable activity (MDA). is defined above with the exception that the measurement is an after the fact estimate of the presence of activity.

2. Net Activity Calculation and Reporting of Results Net activity ior a sample was calculated by subtracting background activity from the sample acdvity. Since the REMP measures extremely smiall changes in radioactivity in the environment, background variaiiorns will result in sample activity being lower than the background activity effecting a Tiegative number.

An MDA was reported in all cases where positive activity was not detected.

Gamma spectroscopy results for each type of sample were grouped as follows:

For surface and drinking eleven nuclides,,Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, Cs-134, Cs-137, Ba-140, and La-140 were reported.

For fish eight nuclides, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Cs-1 34, and Cs-1 37 were reported.

For sediment five nuclides, K-40, Co-58, Co -60, Cs-1 34, and Cs-1 37 were reported.

For air partiuulate six nuclides, Be-7, Mn-54, Co-58, Co-60, Cs-1 34, and Cs-1 37 were reported.

For milk five nuclides, K-40 , Cs-1 34, Cs-1 37, Ba-1 40, and La-1 40 were repoited.

Means and standard deviatoios of the results (including MDA values) were calculated. The standard avheaions r present the variability of measured results for different samples rather than single analysis uncertainty. Including the MDA values will bias the mean calculations high.

D. Program Exceptions For 2001 the PBAPS REMP had a sample collection recovery rate of better than 99%. The exceptions to this program are listed below:

1. Drinking water sampler at locat;on 4L was'out of service for thc following dates:

03/16/2001 to 03/23/2001 due to maintenance work in area.

06/08/2001 to 06/15/2000 due to equipment problems.

A weekly grab sample was taken.

2. Air particulate and air iodine sampiesftorn ,ocdtiw 1lC wer. 1iot available for the period 08/09/2001 to 08/1G/2001 due to a purp failurn. most likel, caused by an electrical storm.

3. The following samples processed by I-BE, the QC iaboratoiy, did not meet the LLDs required by Table -8.&E.2 of the Peach Bottom ODCM:

a. Drinking water- 4L, January, Ba-140 and La-140 The LLDs were missed because samples were not processed in a timely manner. TBE was shipping the QC samples to another laboratory while they were staffing up their laboratory in Knoxville, TN.,

Each program exeption was reviewed to understand the causes of the program exception.

Sampling and. maintenance errors were reviewed .with the personnel involved to prevent a recurrence. Occasional equipment breakdowns and power outages were unavoidable. The overall sample recovery rate indicates that the appropriate procedures and equipment are in place to assure reliable program implementation.

E. Program Changes No changes were made to the REMP in 2001.

IV. Results and Discussion A. Aquatic Environment

1. SuifaceWater.

Samples were collected from two locations monthly (1 LL and 1M). 1LL served as the control location. The following analyses were performed.

Tilium Samples from both locations were analyzed for.concentrations of tritium (Table C-1.1, Appendix C). Results ranged from <106 to 177 pCi/l and averaged 112 pCi/l at the

,cotrol,location and 128 .pCi/I at the. rjdicator location.. Concentrations found were lower.than~those pbserved.duing tha preoperationalperiod.

Gamma Spectromery Samples from both locations were analyzed for conce.ntrati.ons of gamma emitting nuclides (Table C-1.2, Appendix C). All nuclides were less than the MDA.

2. Dikn..ae

- .Sampleswere collected from. two. locations monthly (4L and 61). 61 served as the control location. The following analyses were performed.

Gros Beta Samples from both locations were analyzed for concentrations of gross beta activity in insoluble and soluble fractions. (Tables C-41 I and C-11.2 and Figures C-1 and C-2, SAppen~1iaC)-. *Gross bt ctivity.-in the insoluble fraction ranged from <1.0 to < 1.9 pCii. The values in the soluble fraction ranged from 1.6 to 4.4 pCOI. No differences were observed between the means of the control and indicator stations. The values were generally below those seen in the preoperational period.

Idibm.

Samples from both locations were analyzed for tritium quarterly (Table C-I1.3, Appendix C). The values for the indicator location (4L) ranged from <106 to 177 pCVI with a mean of 126 pCVI. Control location (61) values ranged from <106 to 144 pCV1 with a mean of 118 pCOI. The concentrations found were lower than those observed during the preoperational period.

Gamma Spectrometrv Samples from both locations were analyzed for concentrations of gamma emitting nuclides (Table C-11.4, Appendix C). All nuclides were less than the MDA.

3. Eish Samples were collected from two locations semiannually (4 and 6). The control location was 6. The following analyses were performed.

The edible portion of fish samples from both locations was analyzed for concentrations of gamma emitting nuclides (Table C-l11.1, Appendix C). Naturally occurring K-40 was found at all stations and ranged from 2,328 to 3,232 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found. Figure C-3 illustrates the Cs- 37 actvMty for indicator and control locations from the beginning of the operational period through the present. Cesium-137 activity has declined to non detectable levels.

4. Sediment Samples were collected from three locations semi-annually (4J, 4T and 6F). The controi location was 6F. The follcirg .ana!y.. were performed.

Sediment samples from 0P focatirm's %'re analyzed for concentrations of gamma emitting nudides (Table C-IV.1, Appendix C). Naturally occurring K-40 was found at all locations. K-40 results ranged from 8,711 to 23,482 pCVkg (dry).

Statistfc.ly significant acivitylfor 0s-137 was found at all locations with a mean value of 139 pCVkg (dry) for the indicator locations and 70 pCi/kg (dry) for the control location.

No other fission or acti'aticn products were found. The maxmum calculated dose from this pathway to a teenager's skin was 5.93 E-04 mrem/yr. This value is based upon the assumption the maximum concentrations of Cs-137 at the downstream location (4T) was present the entire year. This dose' represents 0.003% of the allowable fraction of 10 CFR 50, Appendix I limits. Results found were consistent with those from previous years. Figure C-4, Appendix C illustrates the comparison of activities of Cs-137 detected at the control location and indicator locations from the preoperational period through the-present.

B. - Atmospheric Environment

1. Airborne ..  :

a. AirParticulates Samples were collected from five locations (1B, 1Z, IC, 3A, and 5H2).

Control location was 5H2. The following analyses were performed.

GrossBeta Samples from all locations were analyzed for concentrations of gross beta (Tables C-V.1- and C-V.2 and Figures- C-5 and C-6, Appendix C). Air particulate locations were divided into three groups: Group I, consisting of 1B, 1Z, and 1C, located on PBAPS site; Group II,comprised of 3A, located at an intermediate distance from PBAPS;'and Group.1.I, consisting of 5H2, located at a remote distance from PBAPS. The results from these three groups help in

.:-determining the .effects; if any, resulting. from*:the operation of PBAPS. The results from the on-site 'locations 'rgnged from 10 E-3 to 49 E-3 pCVm 3 , with a "mean of 21' E-3 pCVmrn., The 'esults from: intermediate distance location ranged from 9 E-3 to 44..E-3"pCi/m3, with .aý mean of 21 E-3 pCi/M 3. The results from the distant-location ranged fromr 4.E-3 to 38 E-3 pCi/m 3, with a 3

mean of-.20 E-3 .pCimm . -Comparison of tihe values indicates no notable difference among the three groups suggesting no effects from the operation of PBAPS (Figure C-5, Appendix C).

Gamma Spectrometry Weekly samples'from five locations (1B1 3Z, lC, 3A, and 5H2) were composited and analyzed quarterly for the presence of gamma emitting nuclides (Table C-V.3). Naturally occurting Be-7Twas found in all samples with activity values similar to those from the preoperational years. No other fission or activ_.'on nudides were detected.,'

b. *Airborne Iodine Continuous air samples-were collected weekly at five locations (1B, IZ, 1C, 3A, and 5H2) and analyzed for 1-131 via gamma spectroscopy (Table C-VI.1, Appendix C).. Alt results were less thaný MDA.

2. Terrestrial  :

Samples were collected from eleven locations (A, B, C, D, E, J, L, 0, P, R, and S). Farms A, B, C, and E were control locations. The following analyses were performed.

Samples from all locations were analyzed for low level concentrations of 1-131 (Tables C-VII.1, Appendix C). All results were less than MDA.

Gamma a* ejpcrmetry Samples from five locations were analyzed quarterly for concentrations for gamma emitting nuclides (Table C-VII.2, Appendix C). Naturally occurring K-40 was found in all samples with values ranging from 1,260 to 1,587 pCi/I.

All other nuclides searched for were less than MDA. Figure C-7 (Appendix C) illustrates the Cs-137 activity in milk from the beginning of the operational period through the present. Cesium-137 activity has declined to non detectable levels.

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured quarterly at forty-six locations (as described in the program description section) using Panasonic 814 (CaSO 4) thermoluminescent dosimeters.

Each 814 badge has three CaSO4 phosphors. All TLD readings were below 10 mR/std. month with a range of 2.9 to 9.0 mR per standard month (Tables C-VIII.1 through C-VIII.3 and Figure C-8, Appendix C). Except for the fourth quarter, results were consistent with those measured in previous years. The fourth quarter results were about 1 mR to 2 mR higher than results observed inthe other quarters The results were consistent at all stations indicating a non Peach Bottom induced effect.

D. Independent Spent Fuel Storage Installation (ISFSI)

The Independent Spent Fuel Storage Installation (ISFSI) was utilized beginning in June 2000. A total of nine TN-68 casks were each loaded with 68 fuel bundles. As part of the overall REMP, additional TLDs were place at locations near the site boundary and at the nearest resident.

Ec)ept for the fourth quarter data discussed above, no increase in dose was evident due to operation of the ISFSI (Figure C-9, Appendix 0). As a result the doses observed were below both 40CFR190 and 10CFR72.104 limits.

E. Land Use Census A Land Use Census around 1he Peach-Bottom Atomic Power Station (PEBAPS) was conducted by Normandeau Associates, Inc., RMC Environmental Services Division for Exelon Nuclear to comply with Seclon 3.8.E.2 of PBAPS's Offsite Dose Ca!cuiation Manual Specifications (ODCMS) and Bases. The census to lom-te the nearest milk p-cducing animal in each of the sixteen meteorological sectors out to five miles was conducted during the May to October 2001 growing season. The distance and direction of all locations were positioned from the bam to the PBAPS vents using Global Positioning System (GPS) technology.

A small number of goats were discovered in the SSW sector at a distance of 11,414 feet from the vent stacks. Because of the distance from PBAPS and the small number of goats (2-4) the farm was not added to the REMP. The results of this survey are summarized below.

APPENDIX D I-DATA TABLES AND FIGURES COMPARISON LABORATORY

Intentionally Left Blank The following section contains data and figures illustrating the analyses performed by the QC laboratory, Teledyne Brown Engineering (TBE). Duplicate samples were obtained from several locations and media and split between the primary laboratory, Environmental, Inc. and the QC laboratory. Comparison of the results for most media were within expected ranges.

The QC laboratory results for gross beta insoluble and soluble in drinking water samples were very similar to those reported by the Primary laboratory. All results between the laboratories were within 4 pCi/I of each other. The data reported were well within the historical range.

The gross beta results for air particulate samples collected at the collocated stations 1Z (Primary) and 1A (QC) compared very well (Figure D-3). Week No 1 showed the only significant difference between the two collocated samplers. Both results were analyzed by the same laboratory.

Only analyses performed routinely for the REMP are included on this table.

B The Environmental, Inc. value is the mean of 1 or 3 measurements/determinations.

C. The Environmental, Inc. uncertainty is the 2-sigma counting uncertainty for one determination and one standard deviation for three determinations.

D. The DOE EML value is the mean of replicate determinations for each radionuclide.

E. Reporting units are Bq/I for water, Bq/kg (dry) for soil, Bq/kg F. The control limits (min ratio and max ratio) are established by(wet) for vegetation and total Bq for air filters.

DOE EML. Acceptable agreement is achieved if the ratio of the Environmental, Inc. value divided by the DOE EML value falls within the control limits.

G. This naturally-occurring radionuclide is present in the shield background.

No follow-up actions were performed because all of the other gamma scan results were acceptable and the subject result was just outside of the upper control limit.

The control limit concept was established from percentiles of historic data distributions (1982 - 1992). The evaluation of this historic data and development of the control limits are presented in DOE report EML-564. the The control limits listed in this table were developed from percentiles of data distributions for the years 1993 - 1999.
