2003 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 2003 Annual Radiological Environmental Operating Report No. 20.

This report provides the 2003 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 I-131, were found in any pathway modeled by the REMP. Cesium-1 37 levels detected in sediment were similar to those found in previous years. Iodine-1 31 activity was found in two downstream sediment samples and was the result of medical treatments. The calculated dose to the maximum exposed individual from the sediment pathway was 1.29 E-03 mrem. This dose represented 0.006%

of the 10 CFR 20, Appendix I limit of 20 mrem per year for any organ.

If you have any questions, please do not hesitate to contact us.

Sincerely, Ron J.D3?or' Vice President -LGS

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 2003 through 31 December 2003. During that time period, 1,160 analyses were performed on 892 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-137 concentrations consistent with levels observed during the preoperational years. In addition, positive 1-131 activity was found in sediment samples at two downstream indicator locations and was the result of medical treatments. The dose to a teenager's skin through the sediment pathway was calculated as 1.29 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 10CFR20.2002 permitted storage area indicated no offsite radionuclide transport was evident.

IL. 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 prograrn 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 2003 through 31 December 2003.

On 6 July 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 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. -

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.,

IIl. Program Description '

A. Sample Collection Samples for the LGS REMP were collected for Exe'lon Nuclear by Normandeau Associates, RMC Environmental Services Division (RMC).

This section describes the geneoral collectin methods used by RMC to obtain environmental samples for the LGS REMP in 2003. 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 BS-3. '

Aqtuatic Fnvironment

• 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). Qne.additional surface water location (1OF2) 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, 166B2 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. Airbome 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

- A;t approximately one cubic foot per minute. The filters were replaced weekly and sent to the laboratory for analysis.'

'Milk samples were collepted biweekly at five locations (9G1, 10F4, 18C1, 19B1, and 21 B1) 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 Ganmma Radiation' Direct radiation m'e'asurerments were made.using Panasonric 814 calcium sulfate (CaSQ4),t oIurnirescerit dsirmeters.(TLD).' The TLD locations were placed onand around t-)e;LGS'site as f6llow'.:

The specific TLD locations were determin'ed by the following chiteria:

1. ' The presence of 'relatively dense populatio'n; '

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); . . '

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

-1 downwind direction.

Two TLDs -each comprised of three CaSO4 thermoluminescent phosphors enclosed in plastic-were placed at each location in a PVC conduit located approximrately three feet above ground level. The TLDs were exchanged quarterly and sent to ICN foranalysis.

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.

.. ,, . . . . . ..  ; , ,, . I 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 2002. 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, mi!k, 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:

1. Lower I imit 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'counh (above background)'that would be detected with only a 5%/piobability of falsely concluIding that a blank observation represents a "real" signal. -Thle-LLD wasIntended as a before the fact estimate of a system (including instrumentation, procedure and sample type) aid not as an after the fact-criteria-for-the presence of activity. All analyses were designed to achieve the required LGS detestidf capabilities for-envirbnm6ntal sample analysis.

The minimum detectable-activity (MDA)Iis defin6d above with the exception that the mnieas'urement is-an after the fact estimate of the presence of activity.'-

.and lUia-140 were reported.

' For fish eight nuclides,-K-40, Mn-54, Co-58, Fe-59, Co-60,

'Zn-65, Cs 134,'aand Cs-137 were reported.

Forsediment six nuclides, K-40, Mn-;-54,- Co-58, Co-60, Cs-134, and Cs-137 were reported.

For' air particulate six nuclides,'Be-7, Mn-54, Co-58, Co-60, Cs-134, and Cs-137 w'ere reported.

For milk five nuclides',K-40 ,-Cs-i 34, 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.

Ambient"Gafr~rna-Radiation;:.-."- .................

Ambient gamma radiation levels were mreasured 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-VI11.3, Appendix.C.

Most TLD measurementswere'below 10 mRistandard month, with a

• range of 4.7 to 11.4 mR/standard month. A comparison of the Site Boundary and Intermediate Distance data to the Control Location data, indicate that the ambient gamima 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, 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

' 2551 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 Surveyi A Land Use Survey conducted during'the May to September 2003 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 % 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.
