2002 Annual Radiological Environmental Operating Report

Dear Sir:

In accordance with the requirements of Section 3.5 of the Limerick Generating Station (LGS), Units 1 and 2 Offsite Dose Calculation Manual (ODCM), this letter submits the 2002 Annual Radiological Environmental Operating Report No. 19. This report provides the 2002 results for the Radiological Environmental Monitoring Program (REMP) as called for in the Offsite Dose Calculation Manual. In assessing the data collected for the REMP, we have concluded that the operation of LGS, Units 1 and 2 had no adverse impact on the environment. No plant-produced fission or activation products with the exception of Cs-1 37 and Co-60 were found in any pathway modeled by the REMP. Cesium-1 37 levels detected in sediment were similar to those found in previous years. Cobalt-60 activity was found in one downstream sediment sample and was the result of routine liquid effluent discharges. The calculated dose to the maximum exposed individual from the sediment pathway was 1.95 E-03 mrem. This dose represented 0.01 % of the 10 CFR 20, Appendix I limits. If you have any questions, please do not hesitate to contact us. Sincerely, Robert C. Braun Vice President (acting) Attachment cc: H. Miller, Administrator, Region I, USNRC A.

I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Limerick Generating Station (LGS) by Exelon covers the period 1 January 2002 through 31 December 2002. During that time period, 1,246 analyses were performed on 960 samples. In assessing all the data gathered for this report and comparing these results with preoperational data, it was concluded that the operation of LGS had no adverse radiological impact on the environment. Surface and drinking water samples were analyzed for concentrations of tritium and gamma emitting nuclides. Drinking water samples were also analyzed for concentrations of gross beta (soluble and insoluble fractions). No fission or activation products were detected. Gross beta activities detected were consistent with those detected in previous years. Positive tritium activity was detected in 1 of 16 samples. The activity was slightly above the detection level. Fish (predator and bottom feeder) and sediment samples were analyzed for concentrations of gamma emitting nuclides. No fission or activation products were detected in fish. Sediment samples collected below the discharge had Cesium-137 concentrations consistent with levels observed during the preoperational years. In addition, positive Co-60 activity was found in a sediment sample at a downstream indicator location and was the result of LGS releases. The dose to a teenager's skin through the sediment pathway was calculated as 1.95 E-3 mrem. Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. Cosmogenic Be-7 was detected at levels consistent with those detected in previous years. No fission or activation products were detected. High sensitivity 1-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity. Cow milk samples were analyzed for concentrations of 1-131 and gamma emitting nuclides. All 1-131 results were below the minimum detectable activity. Concentrations of naturally occurring K-40 were consistent with those detected in previous years. No fission or activation products were found. Environmental gamma radiation measurements were performed quarterly using thermoluminescent dosimeters. Levels detected were consistent with those observed in previous years. Review of the gamma spectroscopy results from the surface water sampler (25S1) located at the Limerick's intake and downstream of the I OCFR20.2002 permitted storage area indicated no offsite radionuclide transport was evident. 1

II. Introduction The Limerick Generating Station (LGS), consisting of two 3458 MWt boiling water reactors owned and operated by Exelon Corporation is located adjacent to the Schuylkill River in Montgomery County, Pennsylvania. Unit No. 1 went critical on 22 December 1984. Unit No. 2 went critical on 11 August 1989. The site is located in Piedmont countryside, transversed by numerous valleys containing small tributaries that feed into the Schuylkill River. On the eastern river bank elevation rises from approximately 110 to 300 feet mean sea level (MSL). On the western river bank elevation rises to approximately 50 feet MSL to the western site boundary. A Radiological Environmental Monitoring Program (REMP) for LGS was initiated in 1971. Review of the 1971 through 1977 REMP data resulted in the modification-of the program to comply with changes in the Environmental Report Operating License Stage (EROL) and the Branch Technical Position Paper (Rev. 1, 1979). The preoperational period for most media covers the periods 1 January 1982 through 21 December 1984 and was summarized in a separate report. This report covers those analyses performed by Teledyne Brown Engineering (TBE), ICN Pharmaceutical, and Environmental Inc. (Midwest Labs) on samples collected during the period 1 January 2002 through 31 December 2002. On 6 July 1996 a 1 OCFR20.2002 permit was issued to Limerick for storage of slightly contaminated soils, sediments and sludges obtained from the holding pond, cooling tower and spray pond systems. These materials will decay to background while in storage. Final disposition will be determined at Station decommissioning. A. Objective of the REMP The objectives of the REMP are to:

1.

Provide data on measurable levels of radiation and radioactive materials in the site environs.

2.

Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure. B. Implementation of the Objectives The implementation of the objectives is accomplished by:

1.

Identifying significant exposure pathways.

r

2.

Establishing baseline radiological data of media within those pathways.

3.

Continuously monitoring those media before and during Station -operation to assess Station radiological effects (if any) on man and the environment. 111.. Program Description A. Sample Collection Samples for the LGS REMP were collected for Exelon Nuclear by Normandeau Associates;, RMC Environmental Services Division (RMC). This section describes, the general collection methods used by RMC to obtain environmental samples for the LGS REMPI in, 2002. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-1 through B-3, Appendix B. The collection procedures used by RMC are listed in Table B-3. Aquatic Environment -The aquatic environmentwas evaluated by performing radiological analyses on samples of surface water, drinking water; fish, and sediment. Two gallon water samples were collected monthly from continuous samplers located at two surface water locations (13B1 and 24S1) and four drinking water locations (15F4,15F7, 16C2, and 28F3). -One additional surface water location (10F2) was sampled only during the months when water was taken from the Perkiomen Creek for cooling.-, Control locations were 10F2, 24S1, and 28F3. All samples were collected in new unused plastic bottles, which were rinsed at least twice with source water prior to collection. Fish samples comprising the flesh of two groups, catfish/bullhead (bottom feeder) and sunfish (predator), were collected semiannually at two locations,,16C5 and 29C1,(control). Sediment samples composed of recently deposited substrate were collected at three

locations semiannually, 16B2 and 16C4 and 33A2 (control).

Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on samples of air particulate, airborne iodine, and milk. Airborne iodine and particulate samples were collected and analyzed weekly at five locations (10S3, 11S1, 13C1, 14S1, and 22G1). The control location was 22G1. Airborne iodine and particulate samples were obtained at each location, using a vacuum pump with charcoal and glass fiber filters attached. The pumps were run continuously and sampled air at the rate of approximately one cubic foot per minute. The filters were replaced weekly and sent to the laboratory for analysis. Milk samples were collected biweekly at five locations (9G1,1 OF4, 18C1, 19B1, and 21B1)from April through November, and monthly from December through March.- Four additional locations (36E1, 22C1, 23F1 and 25C1) were sampled quarterly. Locations 36E1, 9G1 and 23F1 were controls. All samples were collected in new unused two gallon plastic bottles from the bulk tank at each location, preserved with sodium bisulfite, and shipped promptly to the laboratory. Ambient Gamma Radiation Direct radiation measurements were made using Panasonic 814 calcium sulfate (CaSO4) thermoluminescent dosimeters (TLD). The TLD locations were placed on and around the LGS site as follows: -A site boundary ring consisting of 16 locations (36S2, 3S1, 5S1, 7S1, 10S3, 11S1, 13S2,14S1, 18S2, 21S2, 23S2, 25S2, 26S3, 29S1, 31S1 and 34S2) near and within the site perimeter representing fence post doses (i.e., at locations where the doses will be potentially greater than maximum annual off-site doses) from LGS release. An intermediate distance ring consisting of 16 locations (36D1, 2E1, 4E1, 7E1, 1OE1, 10F3, 13E1, 16F1, 19D1, 20F1, 24D1, 25D1, 28D2, 29E1, 31 D2, and 34E1) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population. The balance of eight locations (5H1, 6C1, 9C1,13C1, 15D1, 17B1, 20D1 and 31D1) 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 of relatively dense population;

2.

Site meteorological data taking into account distance and elevation for each of the sixteen-22 1/2 degree sectors around the site, where estimated annual dose from LGS, if any, would be most significant;

3.

On hills free from local obstructions and within sight of the vents (where practical); I 4., And near the closest dwelling to the vents in the prevailing .downwind direction. Two TLDs -each comprised of three CaSO4 thermoluminescent phosphors enclosed in plastic-.were'placed at each location in a PVC conduit located approximately three feet above ground level. The TLDs were exchanged'quarterly and sent to ICN for analysis.

Data Interpretation The radiological and direct radiation data collected prior to LGS becoming operational wags used as a baseline with which these operational data were compared. For the purpose of this report,. LGS was considered operational at initial criticality. In addition, data were compared to previous years' operational data for consistency and trending. Several factors were important in the interpretation of the data:

1.

Lower Limit of Detection and Minimum Detectable Activity The lower limit of detection (LLD) was defined as the smallest concentration of radioactive material in 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 estimate of a system (including instrumentation, procedure and sample type) and not as an after the fact criteria for the presence of activity. All analyses were designed to achieve the required LGS detection capabilities for environmental sample analysis. 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 for a sample was calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations may result in sample activity being lower than the background activity effecting a negative 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 water 11 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-134, and Cs-137 were reported. For sediment six nuclides, K-40, Mn-54, Co-58, Co-60, Cs-1 34, and Cs-137 were reported. For air particulate six nuclides, Be-7, Mn-54, Co-58, Co-60, Cs-134, and Cs-137 were reported. For milk five nuclides, K-40, Cs-134, Cs-137, Ba-140, and La-140 were reported. Means and standard deviations of the results were calculated. The IrI standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty. D. Program Exceptions, For, 2002 the LGS REMP had a sample recovery rate in excess of 99%. Exceptions are listed below:. 1.'

6.

Air particulate and air iodine samples were not available for the following periods and locations, due to pump failures: 04/22/2002 - 04/29/2002 (week 17), Location 11 S2 11/25/2002 - 12/02/2002 (week 48), Location 14S1.

7.

Milk sample 1-131 results for Location 199B1 collected 11/5/2002 were not reported by the laboratory due to the presence of a non-decaying beta emitter. This laboratory issue was not Limerick specific. Each program exception was reviewed to understand the causes of the program exception. Sampling and maintenance errors were reviewed with the personnel involved to prevent 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 Beginning the second quarter 2002, Teledyne Brown Engineering Environmental Services became the primary laboratory and Environmental Inc. (Midwest Labs) became the QC laboratory. Commencing with the second quarter, sodium bisulfite preservative was added to milk samples to prevent protein binding of iodine. IV. Results and Discussion A. Aquatic Environment

1.

Surface Water Samples were taken from a continuous sampler at three locations (1 OF2, 113B1, and 24S1) on a monthly schedule. Of these locations only 13B1 located downstream, could be affected by Limerick's effluent releases. The following analyses were performed. Tritium Monthly samples from all locations were composited quarterly and analyzed for tritium activity (Table C-1.1, Appendix C). No tritium activity was detected. The highest MDA calculated was <191 pCi/l. I Gamma Spectrometry 'Samples from all locations were analyzed for gamma emitting nuclides (Table C-1.2, Appendix C). All nuclides were less than the MDN'

2.

Drinking Water Monthly samples were collected from continuous water samplers at four locations (15F4,- 15F7, 16C2,-and 28F3). tThree locations (15F4, 15F7, and 16C2) could be affected by Limerick's effluent releases. The following analyses were performed: Gross Beta Samples from all locations were analyzed for concentrations of gross beta in the insoluble and soluble fractions (Tables C-11.1 and C-11.2, Appendix C). The values ranged from <0.6 to <2.2 pCi/I for the insoluble fraction and from <1.2 to 9;7-pCi/I for the soluble fraction. Concentrations detected in both fractions were consistent with those detected in previous years (Figures C-1 and C-2, Appendix C). Tritium Monthly samples from all locations were composited quarterly and analyzed for tritium activity (Table C-11.3, Appendix C). Positive tritium activity was detected in one sample at downstream Location 15F4 at a concentration of 105 pCi/l. The activity detected was slightly above the detection limit. Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-11.4, Appendix C). All nuclides were less than the MDA.

3.

- Fish Fish samples comprised of catfish/bullhead (bottom feeder) and sunfish (predator) were collected at two locations (1 6C5 and 29C1) semiannually. Location 1 6C5 could be affected by Limerick's effluent releases. The following analysis was performed: Gamma Spectrometry The edible portion of fish samples from both locations was analyzed for gamma emitting nuclides (Table C-111.1, Appendix C). Naturally occurring K-40 was found at all stations and ranged from 2,940 to 4,080 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found. Historical levels of Cs-137 are shown in Figure C-3, Appendix C.

4.

Sediment Aquatic sediment samples were collected at three locations (1 6B2, 16C4 and 33A2) semiannually. Of these locations two 16B2 and 16C4 located downstream, could be affected by Limerick's effluent releases. The following analysis was performed: Gamma Spectrometry Sediment samples from all three locations were analyzed for gamma emitting nuclides (Table C-IV.1, Appendix C). Nuclides detected were naturally occurring K-40, and the fission product Cs-1 37. Potassium-40 was found at all stations and ranged from 9,750 to 21,870 pCi/kg dry. Concentrations of the fission product Cs-I 37 were found in sediment samples in all samples. Location 16B2 had the highest average concentration of 222 pCi/kg dry. The activity detected was consistent with those detected in the pre-operational years (Figure C-4, Appendix C). Cobalt-60 at a concentration of 116 pCi/kg dry was found at the downstream indicator station 16B2 and was the result of LGS releases. The does to a teenager's skin through the sediment pathway was calculated as 1.95 E-03 mrem. No other Limerick fission or activation products were found. B. Atmospheric Environment

Air Particulates Continuous air particulate samples were collected from five locations on a weekly basis. The five locations were separated into three groups: Group I represents locations within the LGS site boundary (10S3, 11S1, and 14S1), Group II represents the location at an intermediate distance - 1 1 -

II from the LGS site (13C1); and-Group IlIl represents the control location at a remote distance from LGS (22G1). The following analyses were performed:

Gross Beta i

Weekly samples were analyzed for. concentrations of beta emitters (Table C-V.1 and C'V.2, Appendix C). Detectable gross beta activity was observed, at all locations. Comparison of results among the three groups aid in determining the effects, if any, resulting from the operation of LGS. The results from the OnSiteR locations (Group I) ranged from 7 to 33 E-3 pCUm" with a mean of 18 E-3 - pCi/M3. The results from the Intermediate Distance location (Group II) ranged from 8 to 29 E-3 pCi/M3 with a mean of 18 E-3 pCi/M3. The results fromr the Distant locations (Group l1l) ranged from <7 to 26 E-3 pCi/M3 with a mean of 16 E-3 pCi/M3._ Comparison of the 2002 air particulate data with previous years data indicate no effects from the operation of LGS'(Figure C-5, Appendix C). In addition a comparison of the weekly mean values for 2002'indicate no notable differences among the three groups (Figure C-6, Appendix C). Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table C-V;3, Appendix C). -Naturally occurring Be-7 due to cosmic ray activity was detected in all samples. These values ranged from 48 to 85 E-3 pCi/m3. All other nuclides were less than the MDA.

b.

Airborne Iodine Continuous air samples were collected from five (10S3, 11S1, 14S1, 13C1, and 22G1) locations and analyzed weekly for 1-131 (Table C-VI.1, Appendix C). All results were less than the MDA.

2.

Terrestrial

a.

Milk Samples were collected from five locations (9G1, 10F4, 18C1, 19B1 and 21B1) biweekly April through November and monthly December through March. Samples from four additional locations (22C1, 23F1, 25C1 and 36E1) were taken quarterly. The following analyses were performed: 1odine-131 Milk samples from all locations were analyzed for concentrations of 1-131 (Table C-VII.1, Appendix C). All results were less than the MDA. Gamma Spectrometry Each milk sample from locations 18C1, 199B1, 21 B1 and 22F1 were analyzed for concentrations of gamma emitting nuclides (Table C-VII.2, Appendix C). Naturally occurring K-40 activity was found in all samples and ranged from 1,200 to 1,890 pCi/I. All other nuclides were less than the MDA. C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic 814 (CaSO4) thermoluminescent dosimeters. Forty TLD locations were established around the site. Results of TLD measurements are listed in Tables C-VIII.1 to C-VIII.3, Appendix C. Most TLD measurements were below 10 mR/standard month, with a range of 5.1 to 12.4 mR/standard month. A comparison of the Site Boundary and Intermediate Distance data to the Control Location data, indicate that the ambient gamma radiation levels from the Control Location 5H1 were consistently higher. The historical ambient gamma radiation data from Location 5H1 was plotted along with similar data from the Site, Intermediate Distance and Outer Ring Locations (Figure C-7, Appendix C). Location 5H1 has a historical high bias, but tracked with the data from all three groups. This bias is most likely due to radon emanating from the ground. D. 10 CFR 20.2002 Permit Storage Area The results of the surface water aquatic monitoring program from Location 25S1 were used to determine if radioactivity from the 2002 permit area has made it to the Schuylkill River. The data obtained from the gamma analysis program did not detect any radioactivity from the 2002 permit I area. E. Land Use Survey A Land Use Survey conducted during the May to September 2002 growing season around the Limerick Generating Station (LGS) was performed by Normandeau Associates, RMC Environmental Services Division for Exelon Nuclear to comply with Sections 2.15 'and 3.4.2 of the Plant's Offsite Dose Calculation Manual; -The purpose of the survey was to document the n6arestfresident, milk producing animal and garden of greater than 500 ft2 in each of the sixteen 22 1/2 degree sectors around the site. The distance and direction'of all locati6ns from the LGS reactor buildings were positioned using Global Positioning System (GPS) techiiolog-There were no changes required to the LGS REMP, as a result of this survey.
