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 2004 through 31 December2004. During that time period, 1,150 analyses were performed on 890 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. No tritium activity was detected.

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-1 37 concentrations consistent with levels observed during the preoperational years. No Plant produced fission or activation products were found in sediment.

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 (24S1) located at the Limerick's intake and downstream of the 10CFR20.2002 permitted storage area indicated no offsite radionuclide transport was evident.

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 Programr (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), Global Dosimetry, and Environmental Inc. (Midwest Labs) on samples collected during the period 1 January 2004 through 31 December 2004.

On 6 July 1996 a 10CFR20.2002 permit was issued to Limerick foWr storage of slightly contaminated soils, sediments and sludges obtained from the holding pond, cooling tower and spray pond systemns.- These materials will decay to

background while' in storage. Final disposition will be determined at Station decommissioning.'

A. 'i-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.

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.

Ill. Program Description A. Sample Collection Samples for the LGS REMP were collected for Exelon Nuclear by Nomiandeau Associates, RMC Environmental Services Division (RMC).

This section describes the general collection methods used by RMC to obtain environmental samples for the LGS REMP in 2004. Sample locations and descriptions can be found in Tables B-I and B-2, and Figures B-1 through B-3, Appendix B. The collection procedures used by RMC are listed in Table B-3.

Agiiatic Environment The aquatic environment was 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, catfishlbullhead (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 six locations (9G1,'10F4, 18E1, 19B1, 23F1; and 25C1) from April through November, and monthly from December through March: Two additional locations (36E1 and 22C1) 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 bnundary ring consisting of 16'1ocations (36S2, 3S1, 5S1, 7S1, 10S3, 11 Si, 13S2,14S1,18S2, 21 S2, 23S2, 25S2, 26S3, 29S1, 31 S1 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, 1OEI, 10F3,13E1, 16F1, 19D1, 20F1, 24D1, 25D1, 28D2, 29E1, 31D2, 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); '

--:5-

4. And near the closest dwelling to the vents in the prevailing downwind direction.

Two TLDs - each comprised of three CaSO 4 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 Global for analysis.

I CFR20 2002 Permit Storage Area

1. The results of the surface water sampling program were used to determine if radioactive nuclide transport from the storage area into the Schuylkill River had occurred.

B. Sample Analysis This section describes the general analytical methodologies used by TBE and Midwest Labs to analyze the environmental samples for radioactivity for the LGS REMP in 2004. The analytical procedures used by the laboratories are listed in Table B-3.

In order to achieve the stated objectives, the current program includes the following analyses:

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

2. Concentrations of gamma emitters in surface and drinking water, air particulates, milk, fish, and sediment.

3. Concentrations of tritium in surface and drinking water.

4. Concentrations of 1-131 in air and milk.

5. Ambient gamma radiation levels at various site environs.

C. Data Interpretation The radiological and direct radiation data collected prior to LGS becoming operational was 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:

I ower Limit of Detection and Minimium 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 measiurement 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 I1 riuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb 95, Cs- 34, 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 seven nuclides, Be-7, K-40, Mn-54, Co-58, Co-60, Cs-1 34, and Cs-1 37 were reported.

'For air particulate six nuclides, Be-7, Mn-54, Co-58, Co-G0, Cs-134, and Cs-137 46're reported.'

For milk five'nuclides, K-40, Cs-1 34, Cs-I 37, Ba-140, and La-140 were reported.

'Means and standard deviations of the results were calculated. The I.

standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty.

D. Program Exceptions For 2004 the LGS REMP had a sample recovery rate in excess of 99%.

IV. Results and Discussion A. Aquatic Environment

1. Surface Water Samples were taken from a continuous sampler at three locations (10F2, 13B1, 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.

Trium 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 <198 pCi/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 MDA.

2. Drinking Water Monthly samples were collected from continuous water samplers at four locations (155F4, 15F7, 16C2, and 28F3). Three locations (15F4, 15F7, and 16C2) could be affected by Limerick's effluent releases. The following analyses were performed:

• rkos& Reta 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 <1.4 to 6.1 pCi/I for the insoluble fraction and from <1.8 to 5.2 pCi/l 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). No tritium activity was detected. The highest MDA calculated was <196 pCi/I.

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 (16C5 and 29C1) semiannually., Location 16C5 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 2,920 to 3,590 '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 (16B2, 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:

KG3mm' Spectrometry Sediment samples from all three locations were analyzed for gamma emitting nuclides (Table C-IV.1, Appendix C). Nuclides detected were'naturally occurring Be-7, K40, and the fission product Cs-137.

Beryllium-7 and K-40 were found at all stations and ranged from

<739 to 8,040 and12,400 to 17,000 pCi/kg dry, respectively.

Concentrations of the fission product Cs-1 37 were found in

-sediment samples at all stations. Location 16C4 had the highest average concentration of 183 pCi/kg dry. The activity detected was consistent with those detected in the'pre-operational years (Figure C-4, Appendix C). No other Limerick fission or activation products were found.

a. 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, 11SI, and 14S1),

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

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 On-Site locations (Group I) ranged from <6 to 43 E-3 pCi/M 3 with a mean of 16 E-3 pCiM 3 . The results from the Intermediate Distance location (Group II) ranged from 6 to 29 E-3 pC/rn3 with a mean of 15 E-3 pCi/m 3. The results from the Distant locations (Group l1l) ranged from <7 to 35 E-3 pCi/M 3 with a mean of 16 E-3 pCi/M3 . Comparison of the 2004 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 2004 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 34 to 73 E-3 pCi/M3 . All other nuclides were less than the MDA.

b. Airborne Iodine Continuous air samples were collected from'five locations (10S3, 11S1, 14S1, 13C1, and 22G1) 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 six locations (9G1, 10F4, 18E1, 19B1, 23F1 and 25C1) biweekly April through November and monthly December through March. Samples from two additional locations (36E1 and 22C1) were taken quarterly.

-The following analyses were performed:

-  :-odinee 13-1

'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 Sbectrometry Each milk sample was analyzed for concentrations of gamma emitting nuclides (Table C-VI1.2, Appendix C).

Naturally occurring K-40 activity was found in all samples and ranged from 1,060 to 1,530 pCi/l. 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 aro'und 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 5.0 to 12.5 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 were plotted along with similar data from the Site,

--'13 -

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 24S1 were used to determine if radioactivity from the permit storage area had made it to the Schuylkill River. The data obtained from the gamma analysis program did not detect any migration of radioactivity from the permit storage area.

E. Land Use Survey A Land Use Survey conducted during the May to September 2004 growing season around the Limerick Generating Station (LGS) was performed by Normandeau Associates, RMC Environmental Services Division for Exelon Nuclear to comply with Control 3.3.2 of the Limerick's Offsite Dose Calculation Manual. The purpose of the survey was to document the nearest resident, milk producing animal and garden of greater than 500 ft2 in each of the sixteen 22 Y/2 degree sectors around the site. The distance and direction of all locations from the LGS reactor buildings were positioned using Global Positioning System (GPS) technology. There were no changes required to the LGS REMP, as a result of this survey.

The results of this survey are summarized below.
