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 2001 through 31 December 2001. During that time period, 1,282 analyses were performed on 977 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. Cesium-1 37 levels detected in sediment were consistent with levels detected in previous years and were due to previous plant releases and fallout from nuclear weapons testing. No other LGS-produced fission or activation products were detected 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 I-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 10CFR20.2002 permitted storage area indicated no offsite radionuclide transport was evident.

Introduction The Limerick Generating Station (LGS), consisting of two 3458 MWt boiling water reactors owned and operated by Exelon Corporation (formally PECO Energy), 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 Environmental Inc.
(Midwest Labs), ICN Pharmaceutical and Teledyne Brown Engineering (TBE) on samples collected during the period 1 January 2001 through 31 December 2001.
On July 6, 1996 a 10CFR20.2002 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 while in storage will decay to background. 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.
- 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 Normandeau 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 2001. Sample locations and descriptions can be found in Tables B-1 and B-2, and Figures B-I through B-3, Appendix B. The collection procedures used by RMC are listed in Table B-3.
A.atEnvironment The aquatic envircnment.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 (1 3B1 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 1 0F2, 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 Fn-,i'rinment 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.II
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 0F4, 18C1, 19B1, and 211B1) 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, refrigerated, and shipped promptly to the laboratory. No preservative was added.
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 sixteen locations (36S2, 3S1, 5S1, 7S1, 10S3, 11S1, 13S2, 14S1, 18S2, 21S2, 23.S2,._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 sixteen locations (36D1, 2E1, 4E1, 7E1, I1OE1, 10F3, 13E1, 16F1, 19D1, 20F1, 24D1,:25D1, 28D2, 29E1, 31,D2, and-34E1)* extendihg to approximately 5 miles from the site designed. to measure possible exposures to close-in population.
Thebalance of eight locations (51-1,-6C1, 9C1., 1301; 15D1, 17B1, 20D1 and 31 D1):representing control and-special interests areas such as population centers; schools, etc.z-,:.
The. specific TLD locations, were determined. bythe following criteria:
- 1.
The presence of relatively dense population;
- 2.
Site meteorological data taking.intoaccount.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 sign ifi~ca nt;
- 3.
On hills free from local obstructions and withinsight of the vents (where practical)t-I
- 4.
And near the closest dwelling to the vents in the prevailing downwind direction.
Two TLDs -each comprised of three CaS04 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.

- 1. The.results of the surface water sampling program were used to determine any radioactive nuclide transport from the storage area into the Schuylkill River.
B.
Sample Analysis This section describes the general analytical methodologies used by Midwest:Labs and TBE to.analyze.the environmental samples for radioactivity for the LGS REMP in 2001. The analytical procedures used by the laboratories were 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,ý 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 I'I
factors were important in the interpretation of the data:
L ower Iimit 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 alculatio nn of Re sults 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 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 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-I 34, and Cs-I 37 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 standard deviations represent the variability of measured results for different samples rather than single analysis uncertainty.
D.

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 133B1 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 <160 pCi/I.

Naturally occurring K-40 was found at all stations and ranged from 2,201 to 2,966 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were found.
Historical levels of Cs-1 37 are shown in Figure C-3, Appendix C.
- 4.
Sediment Aquatic sediment gampres were collected at three locations (16B2, 16C4 and 33A2) semiannually. Of these locations two 16B2 and I6C4 located downstream, could be affected by Limerick's effluent re!eases. The following analysis was performed:
14-
Gamma Spactrom.try 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 alt stations and ranged from 11,755 to 15,790 pCi/kg dry. Concentrations of the fission product Cs-137 were found in sediment samples in all samples. Location 16C4 had the highest average concentration of 136 pCi/kg dry. The activity detected was consistent with those detected in the pre operational years (FigureC-4, Appendix C). No other Limerick fission or activation products were found.

Atmospheric Environment 1.
Airborne
- 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 (1 0S3, 11S1, and 14S1),
Group ll.represents the location at an intermediate distance fromthe L.GSsite (13C1), and.Group III represents the
.,control location at apremote distance from LGS (22G 1). The followinganalyses were, performed::.
£ros B t..ta Veekly 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.
Commparisor.of results among the. three groups aid in idetermining 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/min with a mean of 21 E-3 pCi/m 3. The results from the Intermediate Distance location
.(Group 11) -anged fro 74o 43 E-t3.-pCiim 3 with a mean of 21 E-".3 pCi/.
The results from the Distant locations (Group Il) ranged from :8 to 37* -,, pC-i/m3 With a mean of 21 E-3 pCi/m.:. Qomparison of the 2001:. 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 2001 indicate no notable differences among the three groups (Figure C-6, Appendix C).
Gamma Spectrornetry 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 45 to 83 E-3 pCi/m 3. All other nuclides were less than the MDA.
- b.
Airborne Iodine Continuous air samples were collected from five (10S3, 11 S1, 14Sl, 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, 18CI, 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:
1*ndi=.Ml_31 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, 19B1, 211B1 and 22F1 were analyzed for Concentrations of gamma emitting nUclides (Table C-V'L1.2, Appendix C).
Naturally occurring K-40 activity was found in all samples and ranged from 1,235 to 1,681 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 mrad/standard month, with a range of 4.9 to 11,.8 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 area.
E.
Land Use Survey A Land Use Survey conducted during the May to September 2001 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 nearest resident,milk producing animal and garden of greater than 500 ft2 in each of the sixteen 22 1/2A 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.

I ne E-nvironmental, 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/L for water, Bq/kg (dry) forý soil, Bq/kg (wet) for vegetation and total Bq for air filters.
F.
The control limits (min ratio and max ratio) are established by 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 the development of the control limits are presented in DOE report EML-564. The control limits listed in this table were developed from percentiles of data distributions for the years 1993 - 1999.

LIMERICK GENERATING STATION UNITS 1 AND 2 2001 ANNUAL ENVIRONMENTAL OPERATING REPORT (NON-RADIOLOGICAL)

Limerick Generating Station 2001 Annual Environmental Operating Report (Non Radiological)
Introduction This report describes the implementation of the Environmental Protection Plan (EPP), Limerick Generating Station (LGS) Appendix B Technical Specifications, from January 1 through December 31, 2001.
Provided herein are summaries and results of the environmental protection activities required by Subsection 4.2 of the EPP.
2.0 Environmental Protection Activities 2.1 Aquatic Monitoring The Environmental Protection Plan states that the NRC will rely on decisions made by the Commonwealth of Pennsylvania, under the authority of the Clean Water Act, for any requirements for aquatic monitoring. Industrial waste NPDES Permit PA 0051926 provides the mechanism for protecting water quality and, indirectly, aquatic biota. In accordance with the requirements of Section 3 of the Permit, monitoring results were summarized for each month and reported on Discharge Monitoring Reports (DMR) which were submitted to the PA DEP and US EPA.
A summary of the results as reported in the monthly DMRs is presented in Table 1 for discharge points at the Limerick Station and the Bradshaw Reservoir discharge to the East Branch Perkiomen Creek.
In 2001, general observations were made to determine if the exotic zebra mussel was present in the surface waters used for cooling purposes for Limerick Station. Locations were visited upstream and downstream of the Limerick Station site on the Schuylkill River, as well as near the pumping station on the Perkiomen Creek (Graterford, PA). None of the observations revealed any sign of mussel infestation. In addition, general observations were made on several occasions to determine the presence of zebra mussel at several points along the Point Pleasant water diversion route. Sites visited included the diversion outfall structure on the East Branch and several locales along the East Branch Perkiomen Creek water diversion route.
No zebra mussels were found, although Asiatic clams were common at all locations.
Fish tissue samples were collected bi-annually as part of the Radiological Environmental Monitoring Program (REMP) on the Schuylkill River, both upstream and downstream of Limerick
Limerick Generating Station 2001 Annual Environmental Operating Report (Non Radiological)
Generating Station. These collection efforts allow for a descriptive assessment of the fish community in the vicinity of Limerick. Most common were spottail shiner, spotfin shiner, common shiner, carp, goldfish, white sucker, redbreast sunfish, pumpkinseed, smallmouth and largemouth bass, brown and yellow bullhead, and channel and white catfish. Smallmouth bass was one of the most common species of game fish. The species composition of the fish community upstream and downstream of Limerick appeared to be similar.
2.2 Terrestrial Monitoring No terrestrial monitoring is required.
2.3 Maintenance of Transmission Line Corridors Transmission line maintenance records concerning herbicide use are maintained by the PECO Energy Company Consumer Energy Services Group - Power Delivery Division (Electric Transmission and Distribution Department). As required by the LGS Appendix B Technical Specifications, Section 4.2.3, these records can be made available to the NRC upon request.
2.4 Noise Monitoring All noise surveys required by the LGS Final Environmental Statement, Section 5.14.4, Atomic Safety Licensing Board (ASLB) ruling LBP-83-11, dated March 8, 1983, and LGS Appendix B Technical Specifications, Sections 2.3 and 4.2.4. were completed in 1990 for Limerick Generating Station Unit 2 operation and Bradshaw Reservoir. These studies were reported on in the 1990 Annual Environmental Operating Report (Non-radiological). No further noise monitoring is required per LGS Appendix B Technical Specifications, Section 4.2.4.1.
2.5 Environmental Protection Plan There were no Environmental Protection Plan (EPP) non compliances identified by the Nuclear Oversight Department or by Station Self-Assessment in 2001.
2.6 Changes in Station Design or Operation, Tests or Experiments There were no changes in the Limerick Generating Station design or operation and performance of tests or experiments that
Limerick Generating Station 2001 Annual Environmental Operating Report (Non Radiological) required an Environmental Evaluation in accordance with the requirements of Section 3.1 of the Environmental Protection Plan.
2.7 Non-routine Reports Submitted In 2001, one non-routine report containing one incidence of non compliance was submitted in accordance with EPP Section 5.4.2.
Copies of all letters were supplied to the NRC.
The non-routine report was generated to document a hazardous material spill at the Limerick Generating Station (LGS) near the Unit 2 Cooling Tower Sodium Hypochlorite tank at approximately 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br /> on 1/1/2001. The spill occurred due to failed PVC piping used to transfer Sodium Hypochlorite. The likely cause of the failure was ice falling from the nearby cooling tower and hitting the piping. Approximately 20 gallons spilled onto the manmade concrete platform; approximately 1 gallon ran into a dirt area forming a small puddle.
All contamination was contained onsite at the location of the spill.
The spill was cleaned up upon discovery without offsite consequences. The Sodium Hypochlorite that was contained on a manmade surface was immediately cleaned up with assistance from our offsite spill response vendor, Lewis Environmental. The dirt which was contaminated by Sodium Hypochlorite was excavated and placed into a 55-gallon drum for disposal. The ground was frozen at the time of the event, thereby precluding a significant penetration into the soil.
A total of four 55-gallon drums of Sodium Hypochlorite, associated cleanup materials, and soil resulted from the spill. The drums were shipped for disposal.
Subsequent to the event, the station incident commander performed a visual investigation of the area to ensure that all of the Sodium Hypochlorite was cleaned up.
The entire Hypochlorite system was replaced with a new injection system and operational controls were increased. The modification involved the installation of double walled piping and a leak detection system to provide a barrier in preventing further spills.
The operational controls include increased monitoring of the system during operation to identify any potential precursors to spills. An eductor pumping system replaced the positive displacement pumping system to eliminate the excessive dynamic shocks, thereby providing additional assurance that no further spills occur from this system.
