Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Three Mile Island Nuclear Station (TMINS) by AmerGen covers the period 1 January 2004 through 31 December 2004. During that time period, .1,729 analyses were performed on .1338 samples. In assessing all the data gathered for this report and comparing these results with preoperational data, it was concluded that the operation of TMINS had no adyerse radiological impact on the environment.

Surface, drinking, effluent, storm, and ground water samples were analyzed for concentrations of tritium and gamma emitting nuclides. Surface, drinking, and effluent water samples were also analyzed for concentrations of 1-131. Drinking and effluent water samples were also analyzed for concentrations of gross beta.

Effluent water samples were also analyzed for concentrations of Sr-89 and Sr-90.

Ground water samples were also analyzed for concentrations of Sr-90. No Sr-89 and Sr-90 activities were detected. Gross beta, 1-131, and tritium activities detected were consistent with those detected in previous years. lodine-131 detected in surface water was from upstream medical sources. No other fission or activation products attributed to TMI release were detected.

Fish (predator and bottom feeder) and sediment samples were analyzed for concentrations of gamma emitting nuclides. Fish samples were also analyzed for concentrations of Sr-89 and Sr-90. No Sr-89 and Sr-90 activity was detected.

No fission or activation products were detected in fish. Cesium-137 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 TMINS-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 1-131, gamma emitting nuclides, Sr-89 and Sr-90. No 1-131 and Sr-89 activities were detected.

Concentrations of naturally occurring K-40 were consistent with those detected in previous years. Sr-90 activities detected were consistent with those detected in previous years and were attributed to fallout from nuclear weapons testing. No other fission or activation products were found.

Food Product samples were analyzed for concentrations of gamma emitting nuclides (including 1-131) and Sr-90. Sr-90 activities were detected in both the indicator and control samples. This was a result of plant uptake of Sr-90 in soil as a result of past nuclear weapons testing. Concentrations of naturally occurring K-40 were consistent with those detected in previous years. No fission or activation products were detected.

Environmental gamma radiation measurements were performed quarterly using thermoluminescent dosimeters. Levels detected were consistent with those observed in previous years.

A practice of the TMI site is to analyze rodents for radioactivity as a part of the Non-routine REMP. This program is to determine the transport of radioactive materials to unrestricted areas by rodents. Analyses are performed by TMI personnel when samples are available. These results are presented in this report. A pest control program is in place at TMI. This program minimizes the potential for rodents to transport radioactive material to unrestricted areas.

II. Introduction The Three Mile Island Nuclear Station (TMINS), consisting of two pressurized water reactors (PWR), is located on the northern one-half of Three Mile Island in the Susquehanna River approximately 2.5 miles south of Middletown in Londonderry Township, Dauphin County, Pennsylvania. TMI-1 is owned and operated by AmerGen and became'operational in 1974. TMI-2 is operated by GPU Nuclear, Inc. and owned by Metropolitan Edison (50%), Pennsylvania Electric (25%) and Jersey Central Power & Light (25%). TMI-2 became operational in 1978 and was shut down following the 1979 accident. At the end of 1993, TMI-2 was placed in a'condition called Post-Defueling Monitored Storage. TMI-2 is maintained by Amergen under contract with GPU Nuclear.

A Radiological Environmental Monitoring Program (REMP) for TMINS was initiated in 1974. This report covers those analyses performed by Teledyne Brown Engineering (TBE), Global Dosimetry Solutions, Inc., and Environmental Inc. (Midwest Labs) on samples collected during the period 1 January 2004 through 31 December 2004.

A. Objective of the REMP The objectives of the REMP are to.

1. Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure.

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

3. To verify inplant controls for the containment of radioactive

- materials. -

4. To determine buildup of long-lived radionuclides in the environment and changes in background radiation levels.

5. To provide reassurance to the public that the program is capable of

adequately assessing impacts and identifying noteworthy changes in'the radiological statds 6f the environment.

6. To fulfill the requirements of the TMI-I and TMI-2 Technical Specifications.

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 TMINS REMP were collected for AmerGen by Normandeau Associates, RMC Environmental Services Division (RMC).

This section describes the general collection methods used by RMC to obtain environmental samples for the TMINS REMP in 2004. 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 environment was evaluated by performing radiological analyses on samples of surface water, drinking water, effluent water, storm water, ground water, fish, and sediment. Two gallon water samples were collected monthly from continuous samplers located at three surface water locations (A3-2, J1-2 and Q9-1), three drinking water locations (G15-2, G15-3 and Q9-1), and one effluent water location (K1-1). Control locations were A3-2 and Q9-1. Monthly grab water samples were taken from one storm water runoff location (EDCB). Grab ground water samples were collected quarterly at eight locations (48S, GP-1, GP-6, GP-8, GP-9, MS-22, OSF and OS-18), semiannually at 12 locations (GP-12, MS-2, MS-5, MS-8, MS-20, NW-A, NW-B, NW-C, NW-CW, OS-14, RW-1 and RW-2) and annually at seven locations (E1-2, MS-1, MS-4, MS-7, MS-19, MS-21 and N2-1). All water 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, bottom feeder and predator, were collected semiannually at an upstream control (BKG) and a downstream Indicator (IND) location. Location IND could be affected by TMINS' effluent releases. Sediment samples composed of recently deposited substrate were collected semiannually at three locations (J2-1, Kl-3 and Al-3). In addition, one sediment sample was collected annually at the EDCB.iLocation AI-3 was the control.

Atmospheric Environment -' '

The atmospheric environment was evaluated by performing radiological analyses on samples of air particulate, airborne iodine, milk, and Food Product. Airborne iodine and particulate samples were'collected and analyzed weekly at seven locations (A3-1, El-2, F1-3, G2-1, H3-1, M2-1, and Q15-1). The cohtrol location was Q15-1. Airbome 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 four locations (K15-3, D2-1, E2-2, and G2-1) from March through November, and monthly from December through February. The control location was K15-3. 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.

Milk was collected at station F4-1 quarterly as part of the Non-routine REMP.

Food Products were collected annually at two locations (B10-2 and E1-2).

The control location was BI0-2. Four different kinds of samples were collected and placed in new unused plastic bags, and sent to the laboratory for analysis.

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 TMINS site as follows:

A site houndary ring'consisting of 21 locations (A1-4, B1-1, B1-2, C1-2,

'D1-1, E1-4, F1-2, F1-4, G1-3, G1-5, G1-6, H1-1,'1-1, J1-3, K1-4, 1-1, MI-1, N1-3, P1-2, Q1-2, and R1-i) 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 TMINS release.

An offsita ring consisting of 58 locations (A3-1, A5-1, A9-3, B2-1, B5-1, B10-1, C1-1, C2-1, C5-1, C8-1, D1-2, D2-2, D6-1, E1-2, E2-3, E5-1, E7-1, F1-1, F2-1, F5-1, F10-1, G1-2, G2-4, G5-1, H3-1, H5-1, H8-1, J3-1, J5-1, J7-1 K2-1, K3-1, K5-1, K8-1, L1-2, L2-1, L5-1, L8-1, Ml-2, M2-1, M5-1, M9-1, Ni-i, N2-1, N5-1, N8-1, P1-1, P2-1, P5-1, P8-1, Q1-1, Q2-1, Q5-1, Q9-1, R1-2, R3-1, R5-1, and R9-1) extending to approximately 5 miles from the site designed to measure possible exposures to close-in population.

The balance of 11 locations (D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K15-1, L15-1, N15-2, Q15-1, and R15-1) represent control areas.

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 TMINS, 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 downwind direction.

Each TLD station consists of two primary program TLD badges, each of which has three CaSO4 thermoluminescent phosphors enclosed in plastic, placed at each location in a frame located approximately three feet above ground level. Since each TLD responds to radiation independently, this provides six independent detectors at each station. The TLDs were exchanged quarterly and sent to ICN for analysis.

B. Sample Analysis This section describes the general analytical methods used by TBE and Midwest Labs to analyze the environmental samples for radioactivity for the TMINS 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 and effluent water, and air particulates.

2. Concentrations of gamma emitters in surface, drinking, effluent, storm, and ground water,'air particulates, milk, fish, sediment, and Food Product.

3. Concentrations of tritium in surface, drinking, effluent, storm, and ground water.

4. Concentrations of 1-131 in surface,.drinking, and effluent water, air, milk and Food Product.

5. Concentrations of strontium in effluent and ground water, fish, milk, and Food Product.

6. Ambient gamma radiation levels at various site environs.

C. Data Interpretation The radiological and direct radiation data collected prior to TMINS becoming operational was used as a baseline with which these operational data were compared. For the purpose of this report, TMINS 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 TMINS

'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 Calciulation 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, drinking, effluent, storm, and ground 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-I 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-134 and Cs-i 37 were reported.

For milk five nuclides, K-40, Cs-1 34, Cs-137, Ba-140 and La-140 were reported.

For Food Products four nuclides, K-40,1-131, Cs-1 34 and Cs-1 37 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. Program Exceptions For 2004 the TMINS REMP had a sample recovery rate in excess of 99%.

Exceptions are listed below:

1. Air particulate and air iodine samples were not available for the following periods and locations, due to pump failures:

06/16/2004 - 06/23/2004, Location G2-1 08/18/2004 - 08/25/2004, Location M2-1

2. Air particulate and air iodine sample volumes were low for the following periods and locations, due to pump malfunction:

06116/2004 - 06/23/2004, Location E1-2 06/16/2004 - 06/23/2004, Location H3-1 09/15/2004 -09/22/2004, Location El-2Q (Calculated stop date as 09/18/2004)

3. 'Surface water was collected as a grab sample'. The continuous sampler did not operate for one or more hours due to frozen water/ice in sample line, power failure or sampler malfunction:

12/30/2003 - 02/03/2004, Location J1-2 02/03/2004 - 03102/2004, Location J1-2 03/02/2004 - 03/30/2004, Location J1-2 06/01/2004 - 06/29/2004, Location J1-2 and Q9-1 06/29/2004 - 08/03/2004, Location Jl-2 08/03/2004 - 08/31/2004, Location J1-2 08/31/2004 - 09/28/2004, Location J1-2 and Q9-1 12/01/2004 - 12/28/2004, Location J1-2

4. Drinking water was collected as a grab sample. The continuous sampler did not operate for one or more hours due to power failure or pump malfunction: -

06/01/2004 - 06/29/2004, Location Q9-1

5. -TLD station and sample lost due to flooding on the river:

10/10/2004 - 01/10/2005, Location N1 -1 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 l There were no' changes t6 the program in 2004.

IV. Results and Discussion A. Aquatic Environment

1. Surface Water Samples were taken from a continuous sampler at three locations (A3-2, J1-2, and Q9-1) on a monthly schedule. Of these locations only J1-2 located downstream, could be affected by TMINS' effluent releases. The following analyses were performed.

Tritiunm Monthly samples from all locations were analyzed for tritium activity (Table C-1.1, Appendix C). Positive tritium activity was detected in eight of 24 samples, primarily at location J1-2 which is located immediately downstream of the TMINS effluent outfall. All samples ranged from <143 to 4,390 pCi/I. Concentrations detected were consistent with those detected in previous years and were well below any regulatory limits. (Figures C-1 and C-2, Appendix C).

Iodine Monthly samples from location A3-2 were analyzed for iodine-131 activity (Table C-1.2, Appendix C). lodine-131 activity was detected in three samples. The values ranged from <0.4 to 1.4 pCi/I.

Concentrations detected were consistent with those detected in previous years. lodine-131 activity was the result of medical treatments.

Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-1.3, Appendix C). All nuclides were less than the MDA.

B. Atmospheric Environment

1. Airbome

a. Air Particulates Continuous air particulate samples were collected from seven locations on a weekly basis. The seven locations were separated into three groups: Group I represents locations within the TMINS site boundary (E1-2 and F1-3),

Group II represents the location at an intermediate distance from the TMINS site (A3-1, G2-1, M2-1, and H3-1), and Group IlIl represents the control location at a remote distance from TMINS (Q1 5-1). The following analyses were performed:

-Gross Flpt; Weekly samples were'analyzed for concentrations of beta emitters (Table C-VIII.1 and C-VIl.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 TMINS. The results from the On-Site locations (Group I) ranged from <6 to 4T E'3 pCi/M 3 with a mean of 17 E-3 pCi/M 3. The results from the Offsite location (Group II) ranged from' <7 to 34 E-3 pCi/M 3 with a mean of 17 E-3 pCi/M 3. The results from the Control locations (Group l1l) ranged from 8 to 31 E-3 pCi/M3 with a mean of 17 E-3 pCiM 3 . Comparison of the 2004 air particulate data with previous years data indicate no effects from the operation of TMINS (Figure C-6, Appendix C). In addition a comparison of the weekly mean values for 2004 indicate no notable differences among the three groups (Figure C-7, Appendix C).

Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table C-VIII.3, Appendix C).

Naturally occurring Be-7 due to cosmic ray activity was detected in all sarnples. These values ranged from 43 to 82 E-3 pCi/i 3. All other nuclides were less than the MDA.

- results were less than the MDA.

2. Terrestrial -

a. Milk Samples'were collected fromi four locations (K15-3, D2-1,

-E2-2, and G2-1) biweekly March 'through November and monthly December through February. Station F4-1 was sampled quarterly. The following analyses were performed:

lodinl 31 Milk samples from all locations were analyzed for concentrations of 1-131 (Table C-X.1, Appendix C). All results were less than the MDA.

Strontium Milk samples from all locations were composited quarterly and analyzed for Sr-89 and Sr-90 (Table C-X.2, Appendix C). No Sr-89 activity was detected. Sr-90 activity was detected. The values ranged from <0.4 to 1.6 pCi/l. The activity detected was consistent with those detected in the pre-operational years (Figure C-8, Appendix C).

Gamma Spectrometry Milk samples from all locations were analyzed for concentrations of gamma emitting nuclides (Table C-X.3, Appendix C).

Naturally occurring K-40 activity was found in all samples.

The values ranged from 819 to 1,560 pCi/l. All other nuclides were less than the MDA.

b. Food Products Samples were collected from two locations (B10-2 and E1-2) annually. The following analyses were performed:

Strontium Each Food Product sample was analyzed for concentrations of Sr-90 (Table C-XI.1, Appendix C). Sr-90 activity was detected in one sample at 22 pCi/kg wet. Laboratory reanalysis confirmed the result. The hypothetical dose to the maximum exposed individual was 1.75 mrem from consumption of this food product.

Gamma Spectrometry Each Food Product sample was analyzed for concentrations of gamma emitting nuclides (Table C-XI.1, Appendix C).

16 -

Naturally occurring K-40. activity was found in all samples.

The values ranged from 1,550 to 3,540 pCi/I. All other nuclides were less than the MDA.

c. Rodents Gamma Spectrometry One rat from the restricted radiologically clean area was obtained and analyzed for gamma emitting nuclides. All nuclides were less than the MDA.

C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic 814 (CaSO 4) thermoluminescent dosimeters. Fifty-eight TLD locations were established around the site. Results of TLD measurements are listed in Tables C-XII.1 to C-XII.3, Appendix C.

TLD measurements were below 10 mR/standard month, with, a range of

1.6 to 6.3 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 Locations D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K15-1, L15-1, N15-2, Q15-1, and R15-1 were consistently higher. The historical ambient gamma radiation data from Locations D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K15-1, L15-1, N15-2, Q15-1, and R15-1 were plotted along with similar data from the Site, Intermediate Distance and Outer Ring Locations (Figure C-9, Appendix C). Locations D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K1 5-1, LI 5-1, N1 5-2, Q1 5-1, and R1 5-1 have 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. Land Use Survey A Land Use Survey conducted in the September and October 2004 growing season around the Three Mile Island Nuclear Station (TMINS) was performed by Normandeau Associates, RMC Environmental Services Division for AmerGen to comply with Sections 2.15 and 3.4.2 of the Plant's Offsite Dose Calculation Manual (ODCM). The purpose of the survey was to document the nearest resident and milk-producing animal in each of the sixteen 22 1/2 degree sectors around the site. There were no changes required to the TMINS REMP, as a result of this survey. The results of this survey are summarized below.

Results obtained by Environmental. Inc. .Midwest Laboratory as a participant In the Department of Energy's Mixed Anatyte Performance Evaluation Program. Idaho Operations office, Idaho Falls. Idaho b All results are In Bqlkg or Bq/L as requested by the Department of Energy.

a MAPEP results are presented as the known values and expected laboratory precision (1 sigma,1 determination) and control limits as defined by the MAPEP.

d The cause of the deviation seems to be Incomplete dissolution of the sample.

a A spiked soil sample was prepared. Known actIvity', 32.98 pCI/g; laboratory result 33.47 pClIg.

f The sample was reanalyzed with the same results. Investigation Is In progress.

D Based on the results of gamma emitting Isotopes (Cs-137 and Co-60), the filter geometry appears to be biased by -10%. Addition of the summation peak at 1400 KeV results in a recalculaton of 2.12 +/- 0.15 Bqlsample.

h Ratio of Environmental, Inc. to MAPEP results.
