Summary and Conclusions This report on the Radiological Environmental Monitoring Program conducted for the Three Mile Island Nuclear Station (TMINS) by Exelon covers the period 1 January 2014 through 31 December 2014. During that time period, 1,931 analyses were performed on 1,325 samples. In assessing all the data gathered for this report and comparing these results with preoperational data and operational REMP data, it was concluded that the operation of TMINS had no adverse radiological impact on the environment.
Surface, drinking and effluent 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. All groundwater, precipitation water and storm water results are now being reported in the ARGPPR, Appendix G. No Sr-89 and Sr-90 activities were detected.lodine-131 and gross beta concentrations detected were consistent with those detected in previous years. Tritium activity in four surface water samples and monthly effluent water samples was due to TMINS activities or releases.
No other fission or activation products potentially attributed to TMI liquid releases 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-90. No Sr-90 activity was detected.
No fission or activation products were detected in fish samples. Cesium-1 37 was not detected in any sediment samples. Occasionally Cs-137 is detected at very low levels (just above LLD) and is not distinguishable from background levels.Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides.
Gross beta activity is consistent with data from previous years. Cosmogenic Be-7 was detected at levels consistent with those detected in previous years. No other activation products were detected.High sensitivity 1-131 analyses were performed on weekly air samples. All results were less than the minimum detectable activity for 1-131.Cow milk samples were analyzed for concentrations of 1-131, gamma emitting nuclides, Sr-89 and Sr-90. One milk sample was initially positive for 1-131.Upon further investigation, recounting the sample twice showed an increase in activity, which is not congruent with 1-131 decay. Additionally, a gamma spectroscopy analysis was performed on the 1-131 sample, which determined that K-40 was the interfering isotope. No Sr-89, Sr-90 activities were detected.Concentrations of naturally occurring K-40 were consistent with those detected in previous years. Occasionally Sr-90 activities are detected and are consistent with those detected in previous years and were attributed to fallout from nuclear weapons testing. No other fission or activation products were found. No Sr-90 was detected in milk samples for this year.
Food Product samples were analyzed for concentrations of gamma emitting nuclides (including 1-131) and Sr-90. Strontium-90 activity was 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 Be-7 and K-40 were consistent with those detected in previous years.No other fission or activation products were detected.
I Beginning in 2012, Exelon changed the type of dosimetry used for the Radiological Environmental Monitoring Program (REMP). Optically Stimulated Luminescent Dosimetry (OSLD) were deployed and Thermo-luminescent Dosimetry (TLD) were discontinued.
This change resulted in a slight change in process and reporting of quarterly results. The relative comparison to control locations remains valid. OSLD technology is different than that used in a TLD but has the same purpose (to measure direct radiation).
In conclusion, radioactive materials related to TMINS operations were detected in environmental samples, but the measured concentrations were low and consistent with measured effluents.
The environmental sample results verified that the doses received by the public from TMINS effluents in 2014 were well below applicable dose limits and only a small fraction of the doses received from natural background radiation.
Additionally, the results indicated that there was no permanent buildup of radioactive materials in the environment and no increase in background radiation levels.Therefore, based on the results of the radiological environmental monitoring program (REMP) and the doses calculated from measured effluents, TMINS operations in 2014 did not have any adverse effects on the health of the public or on the environment.
II. Introduction The Three Mile Island Nuclear Station (TMINS), consisting of two pressurized water reactors (PWR), is located on the northern end of Three Mile Island in the Susquehanna River approximately
2.5 miles
south of Middletown in Lpndonderry Township, Dauphin County, Pennsylvania.
TMI-1 is owned and operated by Exelon 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 Exelon 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), Landauer and Environmental Inc. (Midwest Labs) on samples collected during the period 1 January 2014 through 31 December 2014.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 status of the environment.
- 6. To fulfill the requirements of the TMI-1 and TMI-2 Technical Specifications.
B. Implementation of the Objectives The implementation of the objectives is accomplished by: 1. Identifying significant exposutre 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 Exelon 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 2014. 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, fish and sediment.
Two gallon water samples were collected monthly from continuous samplers located at two surface water locations (J1-2 and Q9-1), three drinking water locations (G15-2, G15-3 and Q9-1), and one effluent water location (KM-1). A composite of weekly grab samples at one surface water location (A3-2) were collected.
The control locations were A3-2 and Q9-1. All groundwater and storm water results are now being reported in the ARGPPR, Appendix F. All water samples were collected in unused plastic bottles, which were rinsed at least twice with source water prior to collection.
Fish samples comprising the flesh of two groups, bottom feeders and predators, 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 (A1-3, J2-1 and KM-3). In addition, one sediment sample was collected annually at the EDCB. Location A1-3 was the control.Atmospheric Environment The atmospheric environment was evaluated Ihy performing radiological analyses on samples of air particulates, airborne iodine, milk and food product. Airborne iodine and particulate samples were collected and analyzed weekly at seven locations (A3-1, E1-2, FI-3, G2-1, H3-1, M2-1 and Q15-1). The control location was Q15-1. 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.Terrestrial Environment The terrestrial environment was evaluated by performing radiological analyses on samples of milk and food product. Milk samples were collected biweekly at five locations (E2-2, F4-1, G2-1, K15-3 and P4-1)from March through November, and monthly from December through February.
The control location was K1 5-3. 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.
Food products were collected monthly at three locations (B10-2, E1-2 and H 1-2), in lieu of milk sampling and annually from the four food product groups at two locations (B10-2 and H 1-2). B10-2 was the control location for both annual and monthly sampling.
Five different kinds of vegetation samples and ten different kinds of vegetation leaves were collected and placed in new unused plastic bags, and sent to the laboratory for analysis.Ambient Gamma Radiation Beginning in 2012, Exelon changed the type of dosimetry used for the Radiological Environmental Monitoring Program (REMP). Optically Stimulated Luminescent Dosimetry (OSLD) were deployed and Thermo-luminescent Dosimetry (TLD) were discontinued.
This change may result in a step change in readings, up or down, depending on site characteristics.
The relative comparison to control locations remains valid. OSLD technology is different than that used in a TLD but has the same purpose (to measure direct radiation).
The OSLDs were placed at locations on and around the TMINS site as follows: A site boundary ring consisting of 19 locations (A1-4, B1-2, C1-2, D1-1, E1-4, F1-2, F1-4, G1-3, G1-5, G1-6, H1-1, J1-3, K1-4, 1-1I, M1-1, N1-3, P1-2, Q1-2 and R1-1) 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.I I An indicator rinq consisting of 60 locations (A3-1, A5-1, A9-3, B1-1, 12-1, 85-1, 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, J1-1, J3-1, J5-1, J7-1 K2-1, K3-1, K5-1, K8-1, LI-2, L2-1, L5-1, L8-1, M1-2, M2-1, M5-1, M9-1, N1-1, 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 10 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, Lb5-1, N15-2, Q15-1 and R1 5-1) represent control areas.The specific dosimeter 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 station has two A120 3:C Optically Stimulated Luminescence Dosimeters enclosed in plastic placed at each location in a frame located approximately three to six feet above ground level. Since each OSLD responds to radiation independently, this provides two independent detectors at each station.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 2014. 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, and effluent water, air particulates, milk, fish, sediment and food products.3. Concentrations of tritium in surface, drinking and effluent water.4. Concentrations of 1-131 in surface, drinking and effluent water, air, milk and food products.5. Concentrations of strontium in effluent water, fish, milk and food products.6. Ambient gamma radiation levels at various site environs.C. Data Interpretation Data were compared to previous years' operational data for consistency and trending.
In addition, comparison to pre-operational data is sometimes made. For the purpose of this report, TMINS was considered operational at initial criticality.
Several factors were important in the interpretation of the data: 1. Lower Limit of Detection and Minimum Detectable Concentration 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 concentration (MDC) 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 affecting a negative number. An MDC 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, and effluent water 11 nuclides, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-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-134 and Cs-137 were reported.For air particulate eight nuclides, Be-7, Mn-54, Co-58, Co-60, Nb-95, Zn-95, Cs-134 and Cs-137 were reported.For milk five nuclides, K-40, Cs-1 34, Cs-1 37, Ba-140 and La-140 were reported.For food products five nuclides, Be-7, K-40, 1-131, Cs-134 and Cs-137 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 2014 the TMINS REMP had a sample recovery rate in excess of 99%.Issue Reports (IR) were initiated to document significant exceptions and missing samples.

- 2. G15-2 During sampling period 2/25/14 to 3/5/14, sampler had an error, per data logger FLOAT/WEIGHT TRIPPED, 119 samples were collected.
Sufficient sample volume was collected and no grab sample required.During sampling period 3/5/14 to 3/11/14, sampler was found with no LCD on ISCO and unable to retrieve data from data logger. The cause for the malfunction is not known. The electronics were replaced and the unit was calibrated on 3/11/14. Sufficient sample volume was collected and no grab sample required. (IR 1662133)3. A3-2 Due to Swatara Creek being frozen over could not break ice and collect grab sample for 1/21/14-1/28/14 sampling period. January composite will consist of 3 rather than 4 samples. (IR 1617591)4. Q9-1 Drinking Water For the sampling period 6/24/14-7/1/14, No weekly sample was available and a grab sample was collected.
The suction strainer was found not submerged in the source bucket. Suspect strainer did not reseat in source water bucket after sample collection on 6/24/14.During previous weekly sample collection the regular TMI REMP sampler was on vacation.
Backup sampler was coached to self check and ensure first sample after collection operates correctly.
A supplier FMS observation was submitted to document inadequate human performance. (IR 2115414)5. G15-2 For the sampling periods 7/22/14-7/29/14 and 7/29/14-8/5/14, there were low collection volumes in the compositor.
Sufficient sample was collected for analyses and no grab samples were required.
The lost volume was due to ISCO hose problems and the hose was replaced on 7/30/14. (IR 2423641)Milk 1. K15-3 Control The 7/23/14 sample initially showed activity for 1-131. The sample was recounted two days later and again the next day. Both recounts showed an increase in activity.
These results are not congruent with normal 1-131 decay. A gamma scan was then performed and K-40 was detected.
The non-decaying activity was attributed to this naturally occurring isotope. No 1-131 analysis result is available for this sample.
Dosimeter 1. A5-1 New pole recently installed.
Old pole still standing but third quarter dosimeters not attached/found.
The dosimeters were presumably removed and discarded by utility personnel during new pole installation.
Fourth quarter dosimeters mounted on newly installed pole. (IR 2384588)2. E5-1 New pole recently installed.
Per personnel (who were present) old pole will be removed. Fourth quarter dosimeters mounted on newly installed pole instead. (IR 2384588)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 No program changes for 2014.IV. Results and Discussion A. Aquatic Environment
- 1. Surface Water Samples were taken weekly from a continuous sampler at two locations (J1-2 and Q9-1) and weekly grab samples from one location (A3-2). Weekly samples were composited on a monthly schedule.
Of these locations only J1-2 located downstream could be affected by TMINS' effluent releases.
The following analyses were performed:
Tritium Monthly samples from J1-2 and Q9-1 were analyzed for tritium activity (Table C-1.1, Appendix C). Positive tritium activity was detected in four of 12 samples at location J1-2 which is located immediately downstream of the TMINS effluent outfall. The concentrations ranged from 291 to 2,280 pCi/l. The increased tritium concentrations detected were a result of TMINS releasing radwaste treatment system effluent water under permitted discharges in accordance with NRC regulations.
The indicator surface water sample is taken just downstream of the liquid discharge outfall where mixing of liquid effluents with the river water is incomplete.
More complete mixing is not achieved until liquid effluents pass over the York Haven Dam. This water is normally not consumed by humans. The concentrations detected were well below any regulatory limits (Figures C-1 and C-2, Appendix C).Iodine Monthly samples from location A3-2 were analyzed for 1-131 activity (Table C-1.2, Appendix C). This is a control or background station sampled because known medical discharges of radiopharmaceuticals occur into the surface water upstream of TMI from a nearby hospital.Gamma Spectrometrv Locations J1-2 and Q9-1 were analyzed for gamma emitting nuclides (Table C-1.3, Appendix C). All nuclides were less than the MDC.2. Drinking Water Monthly samples were collected from continuous water samplers at three locations (G15-2, G15-3 and Q9-1). Two locations (G15-2 and G15-3) could be affected by TMINS' effluent releases.
The following analyses were performed:
Gross Beta Monthly samples from all locations were analyzed for concentrations of gross beta (Tables C-I1.1, Appendix C). Gross beta activity was detected in 22 of 36 samples. The concentrations ranged from 1.9 to 4.2 pCi/l. Concentrations detected were consistent with those detected in previous years (Figure C-3, Appendix C).Iodine Monthly samples from all locations were analyzed for concentrations of 1-131 (Table C-11.2, Appendix C). lodine-131 activity was not detected in any samples.Tritium Monthly samples from all locations were analyzed for tritium activity (Table C-11.3, Appendix C). Tritium was not detected in any samples (Figures C-4, Appendix C).Gamma Spectrometry Samples from all locations were analyzed for gamma emitting nuclides (Table C-11.4, Appendix C). All nuclides were less than the MDC.3. Effluent Water Monthly samples were collected from a continuous water sampler at one location (K1-1). The following analyses were performed:
Gross Beta Monthly samples from location K1-1 were analyzed for concentrations of gross beta (Tables C-111.1, Appendix C). Gross beta was detected in all 12 samples. The concentrations ranged from 2.8 to 7.0 pCi/l. Concentrations detected were consistent with those detected in previous years.Iodine-1 31 Monthly samples from location K1-1 were analyzed for concentrations of 1-131 (Tables C-111.1, Appendix C). lodine-131 was not detected in any of the samples.Tritium Monthly samples from location K1-1 were analyzed for tritium activity (Table C-111.1, Appendix C). Tritium activity was detected in 4 of 12 samples. The concentrations ranged from 2,300 to 27,000 pCi/I. The elevated results were a result of TMI releasing radwaste treatment system effluent water under permitted discharges in accordance with NRC regulations.
These results were from the liquid discharge mixing basin. The concentrations detected agree with those obtained from the TMINS Effluent Monitoring Program.The concentrations were well below any regulatory limits. (Figure C-4, Appendix C)Strontium Semiannual composite samples from location K1-1 were analyzed for Sr-89 and Sr-90 (Table C-I11.1, Appendix C). No strontium activity was detected.
The highest MDC was calculated at <4.6 pCi/I for Sr-89 and at <0.9 pCi/I for Sr-90.Gamma Spectrometry Samples from location K1-1 were analyzed for gamma emitting nuclides (Table C-I11.2, Appendix C). All nuclides were less than the MDC.4. Storm Water Storm water results are now included in the Annual Radiological Groundwater Protection Program (ARGPPR), Appendix F.5. Ground Water Groundwater results are now included in the Annual Radiological Groundwater Protection Program (ARGPPR), Appendix F.6. Fish Fish samples comprised of bottom feeders and predators were collected at two locations (IND and BKG) semiannually.
Location IND could be affected by TMINS' effluent releases.
The following analyses were performed:
Strontium The edible portions of fish samples from both locations were analyzed for Sr-90 (Table C-IV.1, Appendix C). No strontium activity was detected.
The highest MDC was calculated at <3.7 pCi/kg wet for Sr-90.
Gamma Spectrometrv The edible portions of fish samples from both locations were analyzed for gamma emitting nuclides (Table C-IV.2, Appendix C).Naturally occurring K-40 was found in all fish samples and ranged from 2,411 to 3,869 pCi/kg wet and was consistent with levels detected in previous years. No fission or activation products were detected.7. Sediment Aquatic sediment samples were collected at three locations (A1-3, J2-1 and K1-3) semiannually.
Of these locations two (J2-1 and KI-3) could be affected by TMINS' effluent releases.
The following analysis was performed:
Gamma Spectrometrv Sediment samples from all locations were analyzed for gamma emitting nuclides (Table C-V.1, Appendix C). Potassium-40 was found in all sediment samples and ranged from 8,369 to 17,610 pCi/kg dry. No other fission or activation products were detected.Cesium-1 37 is occasionally found in sediment at very low levels (just above LLD) and is not distinguishable from background levels (Figure C-5, Appendix C).B. Atmospheric Environment 1 .Airborne Particulates
- a. Air Particulates Continuous air particulate samples were collected from seven locations on a weekly basis. Six locations (A3-1, E1-2, F1-3, G2-1, H3-1 and M2-1) were indicator stations located in the highest D/Q sectors and the nearest communities to TMI. One sample (Q15-1) represents the control location at a remote distance from TMINS. The following analyses were performed:
Gross Beta Weekly samples were analyzed for concentrations of beta emitters (Table C-VI.1 and C-VI.2, Appendix C).
Detectable gross beta activity was observed at all locations.
Comparison of results aid in determining the effects, if any, resulting from the operation of TMINS. The results from the closest to the site boundary locations (Group I) ranged from 8 to 32 E-3 pCi/m 3 with a mean of 16 E-3 pCi/m 3.The results from the intermediate offsite locations (Group II)ranged from 6 to 38 E-3 pCi/m 3 with a mean of 17 E-3 pCi/m 3.The results from the Control location (Group Ill)ranged from 9 to 31 E-3 pCi/m 3 with a mean of 17 E-3 pCi/m 3.Comparison of the 2014 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 2014 indicate no notable differences between indicator and control stations (Figure C-7, Appendix C).Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma emitting nuclides (Table C-VI.3, Appendix C).Naturally occurring Be-7 due to cosmic ray activity was detected in 26 samples. These concentrations ranged from 37 to 102 E-3 pCi/m3. All other nuclides were less than the MDC.b. Airborne Iodine Continuous air samples were collected from seven (A3-1, E1-2, F1-3, G2-1, H3-1, M2-1 and Q15-1) locations and analyzed weekly for 1-131 (Table C-VII.1, Appendix C). All results were less than the MDC for 1-131.2. Terrestrial
- a. Milk Samples were collected from five locations (K1 5-3, E2-2, F4-1 G2-1 and P4-1) biweekly March through November and monthly December through February.
The following analyses were performed:
Iodine-1 31 Milk samples from all locations were analyzed for concentrations of 1-131 (Table C-VIII.1, Appendix C). The K15-3 sample collected on 07/23/14 initially showed activity for 1-131. The sample was recounted two days later and again the next day. Both recounts showed an increase in activity.
These results are not congruent with normal 1-131 decay. A gamma scan was then performed and K-40 was detected.
The non-decaying activity was attributed to this naturally occurring isotope. No 1-131 analysis result is available for this sample. All other results were less than the MDC.Strontium Milk samples from all locations were composited quarterly and analyzed for Sr-89 and Sr-90 (Table C-VIII.2, Appendix C). No Sr-89 or Sr-90 activity was detected.
Occasionally Sr-90 is detected and is 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-VIII.3, Appendix C).Naturally occurring K-40 activity was found in all samples.The concentrations ranged from 636 to 1,517 pCi/l. All other nuclides were less than the MDC.b. Food Products Food products were collected monthly at three locations (B10-2, E1-2 and H1-2), in lieu of milk sampling and annually from the four food product groups at two locations (B10-2, E1-2 and H1-2). B10-2 was the control location for both annual and monthly sampling.
The following analyses were performed:
Strontium Twenty-six of 32 food product samples were analyzed for concentrations of Sr-90 (Table C-IX.1, Appendix C).Strontium-90 activity was detected in 11 of 26 samples. The concentrations ranged from 2 to 18 pCi/kg wet.
Gamma Spectrometry Each food product sample was analyzed for concentrations of gamma emitting nuclides (Table C-IX.1, Appendix C).Naturally occurring Be-7 due to cosmic ray activity was detected in 14 of 32 samples. These concentrations ranged from 353 to 2,515 pCi/I. Naturally occurring K-40 activity was found in all samples. The concentrations ranged from 1,672 to 8,693 pCi/I. All other nuclides were less than the MDC.C. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Optically Stimulated Luminescence Dosimeter (OSLD). Ninety OSLD locations were established around the site. Results of OSLD measurements are listed in Tables C-X.1 to C-X.3, Appendix C All of the OSLD measurements were below 40 mR/quarter, with a range of 16.2 to 37.4 mR/standard quarter. A comparison of the Site Boundary and Indicator 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 averaged higher than indicator stations.
Locations D15-1, F25-1, G10-1, G15-1, H15-1, J15-1, K15-1, L15-1, N15-2, Q15-1 and R15-1 have a historical high bias, but tracked with the data from all three groups this bias is most likely due to radon and other naturally occurring nuclides, e.g. K-40, emanating from the ground.D. Land Use Survey A Land Use Survey conducted in the July through November 2014 growing season around the Three Mile Island Nuclear Station (TMINS)was performed by Normandeau Associates, RMC Environmental Services Division for Exelon to comply with Sections 8.2 of the Plant's Offsite Dose Calculation Manual (ODCM). 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 /2 degree sectors around the site. For 2014, a meat census was also performed.
The results of these surveys are summarized below.

Radiological Impact of TMINS Operations An assessment of potential radiological impact indicated that radiation doses to the public from 2014 operations at TMINS were well below all applicable regulatory limits and were significantly less than doses received from natural sources of radiation.
The 2014 whole body dose potentially received by an assumed maximum exposed individual from TMI-1 and TMI-2 liquid and airborne effluents was conservatively calculated to be 0.12 mrem. This dose is equivalent to 0.04% of the dose that an individual living in the TMI area receives each year from natural background radiation.
- 1. Determination of Radiation Doses to the Public Dose assessments can be performed by using either effluent data and an environmental transport model or environmental sample data. To the extent possible, doses to the public are based on the direct measurement of dose rates from external sources and the measurement of radionuclide concentrations in environmental media which may contribute to an internal dose of radiation.
Optically Stimulated Luminescent Dosimetry (OSLDs) positioned in the environment around TMINS provide measurements to determine external radiation doses to humans. Samples of air, water and food products are used to determine internal doses.The quantity of radioactive materials released during normal operations are typically too small to be measured once distributed in the offsite environment.
Therefore, the potential offsite doses are more effectively calculated for TMINS operations using a computerized model that predicts concentrations of radioactive materials in the environment and subsequent radiation doses based on measured effluents.
Doses are calculated using a model that incorporates the guidelines and methodology set forth by the USNRC in Regulatory Guide 1.109 and NUREG 0133. Due to the conservative assumptions that are used in the model, the calculated doses are generally higher than the doses based on actual environmental sample concentrations.
Therefore, the model predicts doses that are higher than actual doses received by people. The type and amount of radioactivity released from TMINS is calculated using measurements from effluent sample analyses.Airborne releases are diluted and carried away from the site by atmospheric diffusion, which continuously acts to disperse radioactivity.
Variables that affect atmospheric dispersion include wind speed, temperature at different elevations, terrain, and shift in wind direction.
A weather station on the north end of TMI is linked to a data logger that records the meteorological data.Computer models also are used to predict the downstream dilution and travel times for liquid releases into the Susquehanna River.Actual monthly Susquehanna River flows are obtained from the USGS Stream gauging station 01570500 located at Harrisburg, PA.The human exposure pathways also are included in the model and are depicted in Figure 1. The exposure pathways that are considered for the discharge of TMINS liquid effluents are consumption of drinking water and fish. The exposure pathways considered for the discharge of TMINS airborne effluents are plume exposure, inhalation, cow milk consumption, fruit and vegetable consumption, and meat consumption.
When determining the dose to humans, it is necessary to consider all applicable pathways and all exposed tissues, summing the dose from each to provide the total dose for each organ as well as the whole body from a given radionuclide.
Dose calculations involve determining the energy absorbed per unit mass in the various tissues. Thus, for radionuclides taken into the body, the metabolism of the radionuclide in the body must be known along with the physical characteristics of the nuclide such as energies, types of radiations emitted and half-life.
The dose assessment model also contains dose conversion factors for the radionuclides for each of four age groups (adults, teenagers, children and infants) and eight organs (total body, thyroid, liver, skin, kidney, lung, bone and GI tract).2. Result of Dose Calculations The maximum hypothetical doses due to 2014 TMI-1 and TMI-2 liquid and airborne effluents are summarized in Tables 1 and 2.Table 1 compares the calculated maximum hypothetical individual doses to the USNRC 10 CFR 50 App. I guidelines.
This table also compares the calculated doses (to an individual of the public) from effluents and direct radiation to USEPA 40 CFR 190 dose limits.Table 2 presents the maximum hypothetical whole body doses to an individual.
As shown in Table 1, the doses calculated for 2014 operations at TMINS were well below the Federal dose limits (USEPA 40 CFR 190) and the guidelines of USNRC 10 CFR 50 App. I. This conclusion was supported by radionuclide concentrations detected in actual environmental samples.Doses from natural background radiation provide a baseline for assessing the potential public health significance of radioactive effluents.
Natural background radiation from cosmic, terrestrial and natural radionuclides in the human body (not including radon), averages about 81 mrem/yr (Ref. 5). Additionally, the average individual living in the United States receives an annual dose of about 2,760 mrem to the lung from natural radon gas. This lung dose is considered to be equivalent to a whole (or total) body dose of 230 mrem (Ref. 5). Therefore, the average person in the United States receives a whole body dose of about 311 mrem/yr from natural background radiation sources.As shown on Table 2, the maximum hypothetical whole body dose received by an individual from 2014 TMI-1 and TMI-2 liquid and airborne effluents combined was conservatively calculated to be 0.12 mrem. This dose is equivalent to 0.04% percent of the dose that an individual living in the TMI area receives each year from natural background radiation (311 mrem).The low doses calculated for 2014 TMINS operations were the result of efforts to maintain releases "as low as reasonably achievable" (ALARA).
In conclusion, radioactive materials related to 2014 TMINS operations were detected in environmental samples, but the measured concentrations were low and consistent with measured effluents.
The environmental sample results verified that the doses received by the public from TMINS effluents in 2014 were well below applicable dose limits and only a small fraction of the doses received from natural background radiation.
Additionally, the results indicated that there was no permanent buildup of radioactive materials in the environment and no increase in background radiation levels.Therefore, based on the results of the radiological environmental monitoring program (REMP) and the doses calculated from measured effluents, TMINS operations in 2014 did not have any adverse effects on the health of the public or on the environment.

The direct radiation dose is calculated from environmental dosimeter data. For this calculation, exposure is assumed to be equal to dose.The direct radiation dose from 2014 TMINS operations was 0.65 mrem. This dose was based on a maximum net fence-line exposure rate and a shoreline/fence-line occupancy factor of 67 hours7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br /> (Regulatory Guide 1.109). The combination of the maximum organ dose from TMI-I and TMI-2 effluents (0.12 mrem) and the dose from direct radiation (0.65 mrem) yielded a maximum hypothetical dose of 0.77 mrem.

Errata Data There is no errata data for 2014.G. Summary of Results -Inter-Laboratory Comparison Program The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation and water matrices (Appendix E). The PE samples, supplied by Analytics Inc., Environmental Resource Associates (ERA) and DOE's MAPEP, were evaluated against the following pre-set acceptance criteria: 1. Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of TBE's result and Analytics' known value. Since flag values are not assigned by Analytics, TBE-ES evaluates the reported ratios based on internal QC requirements, which are based on the DOE MAPEP criteria.2. ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's acceptance limits are established per the USEPA, NELAC, state specific PT program requirements or ERA's SOP for the Generation of Performance Acceptance Limits, as applicable.
The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.3. DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values.The MAPEP defines three levels of performance:
Acceptable (flag = "A"), Acceptable with Warning (flag = "W"), and Not Acceptable (flag = "N"). Performance is considered acceptable when a mean result for the specified analyte is +/- 20% of the reference value. Performance is acceptable with warning when a mean result falls in the range from +/-20% to +/-30% of the reference value (i.e., 20% < bias < 30%). If the bias is greater than 30%, the results are deemed not acceptable.
In reviewing our environmental inter-laboratory crosscheck programs, we identified
- 1) duplication of efforts on some matrices and isotopes and 2) that we are performing crosscheck samples on some matrices and isotopes that we do not perform for clients.Since the DOE MAPEP is designed to evaluate the ability of analytical facilities to cprrectly analyze for radiological constituents representative of those at DOE sites, the needed changes were made to the MAPEP program. Therefore, the following isotopes were removed from the MAPEP program: Soil -gamma -will be provided by Analytics twice per year, starting in 2015. For 2014, one soil gamma is provided by MAPEP, the 2 nasoil gamma is provided by Analytics.
AP -gamma -is currently provided by Analytics.
Water -gamma, H-3, Sr-90, uranium, gross alpha and gross beta currently provided by ERA.MAPEP evaluates non-reported (NR) analyses as failed if they were reported in the previous series.For the TBE laboratory, 163 out of 169 analyses performed met the specified acceptance criteria.
Six analyses (Ni-63, K-40 and 1-131 in water, and two Sr-90s and one Gross Alpha in AP samples) did not meet the specified acceptance criteria for the following reasons: 1. Teledyne Brown Engineering's MAPEP March 2014 Ni-63 in water result of 32.7 +/- 1.69 Bq/L was overlooked when reporting the data but would have passed the acceptance range of 23.9 -44.2 Bq/L. NCR 14-04 2. Teledyne Brown Engineering's MAPEP March 2014 K-40 in water result of 1.63 +/- 2.49 Bq/L was overlooked when reporting the data but would have passed the false positive test. NCR 14-04 3. Teledyne Brown Engineering's ERA November 2014 1-131 in water result of 15.8 pCi/L was lower than the known value of 20.3 pCi/L, failing below the lower acceptance limit of 16.8.The result was evaluated as failed with a found to known ratio of 0.778. No cause could be found for the slightly low result. All ERA 1-131 evaluations since 2004 have been acceptable.
NCR 14-08 4. Teledyne Brown Engineering's MAPEP March 2014 Sr-90 in AP result of 0.822 Bq/sample was lower than the known value of 1.18 Bq/sample, failing below the lower acceptance limit of 0.83 Bq/sample.
The rerun result was still low, but fell within the lower acceptance range of 0.836. The rerun result was statistically the same number as the original result. No cause could be found for the slightly low results.NCR 14-04 5. Teledyne Brown Engineering's MAPEP September 2014 Sr-90 in AP result of 0.310 Bq/sample was lower than the known value of 0.703 Bq/shmple.
The gravimetric yield of 117% was very high (we normally see yields of 60% to 70%) and could account for the low activity.
NCR 14-09 6. Teledyne Brown Engineering's MAPEP September 2014 Gr-Alpha in AP result of 0.153 Bq/sample was lower than the known value of 0.53 Bq/sample.
The AP sample was counted on the wrong side. The AP was flipped over and recounted with acceptable results. NCR 14-09 For the EIML laboratory, 85 of 90 analyses met the specified acceptance criteria.
Five analyses (Water -Pu-238, Pu-239, Fe-55; AP -Co-57; Soil, Cs134) did not meet the specified acceptance criteria for the following reasons: 1. Environmental Inc., Midwest Laboratory's MAPEP February 2014 water Pu-238 result of 1.28 Bq/L was higher than the known value of 0.83 Bq/L, exceeding the upper control limit of 1.08 Bq/L. The high bias on the plutonium was traced to contamination from a newly purchased standard.
The result of the reanalysis with the new tracer was 0.68, which fell within the acceptance criteria.2. Environmental Inc., Midwest Laboratory's MAPEP February 2014 water Pu-239/240 result of 0.91 Bq/L was higher than the known value of 0.68 Bq/L, exceeding the upper control limit of 0.88 Bq/L. The high bias on the plutonium was traced to contamination from a newly purchased standard.The result of reanalysis with the new tracer was 0.66 Bq/L, which fell within the acceptance criteria.3. Environmental Inc., Midwest Laboratory's MAPEP February 2014 AP Co-57 result of 1.60 +/- 0.05 Bq/total sample failed the false positive test. Interference from the Eu-1 52 resulted in the misidentification of Co-57.4. Environmental Inc., Midwest Laboratory's MAPEP February 2014 soil Cs-134 result of 6.10 +/- 1.80 Bq/kg failed the false positive test. Long sample counting time lead to interference from naturally occurring Bi-214 in the sample matrix with a close spectral energy.
- 5. Environmental Inc., Midwest Laboratory's MAPEP August 2014 water Fe-55 result of 55.10 +/- 14.80 Bq/L was higher than the known value of 31.50 Bq/L, exceeding the upper control limit of 41.00 Bq/L. The result of the reanalysis of tFe-55 was 32.63 +/- 16.30 Bq/L, which fell within thp acceptance criteria.The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.V.

Summary and Conclusions In 2006, Exelon instituted a comprehensive program to evaluate the impact of station operations on groundwater and surface water in the vicinity of Three Mile Island Nuclear Station. At Three Mile Island Nuclear, 31 new permarent groundwater monitoring wells were installed in 2006. The results for all TMI wells are included in this report. This report covers groundwater, surface water, storm water and precipitation samples collected from the environment, both on and off station property in 2014. During that time period 694 analyses were performed on 258 samples from 68 locations.
In assessing all the data gathered for this report, it was concluded that the operation of Three Mile Island Nuclear Station had no adverse radiological impact on the environment.
Gamma-emitting radionuclides associated with licensed plant operations were not detected at concentrations greater than their respective Lower Limits of Detection (LLDs) as specified in the Offsite Dose Calculation Manual (ODCM) in any of the groundwater, surface water, storm water and precipitation samples. In the case of tritium, Exelon specified that its laboratories achieve a lower limit of detection 10 times lower than that required by federal regulation.
Strontium-89 and strontium-90 were not detected at a concentration greater than their respective LLD of 10 and 1 picoCurie per liter (pCi/L) in the groundwater samples tested.Tritium was not detected in any groundwater, surface water, storm water or precipitation water samples at concentrations greater than the United States Environmental Protection Agency (USEPA) drinking water standard (and the Nuclear Regulatory Commission Reporting Limit) of 20,000 pCi/L. Low levels of tritium were detected at concentrations greater than the LLD of 200 pCi/L in 30 of 60 groundwater monitoring locations.
The groundwater tritium concentrations ranged from 184 +/- 115 pCi/L to 17,700 + 1,810 pCi/L. Tritium that was detected in groundwater at the Station is believed to be the result of a potential leak, historical releases, the recapture of gaseous tritium releases via rainwater and/or background from external sources greater than 200 pCi/L. Tritium was detected in three of four precipitation water locations.
The concentration ranged from 246+/- 83 to 2,470 + 299 pCi/L. Tritium was not detected at any surface water location.
Tritium was detected in two storm water samples. The concentrations ranged from 289 +/- 118 to 312 +/- 114 pCi/L.Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during the second quarter sampling in 2014. Gross Alpha (dissolved) was not detected at any of the groundwater locations.
Gross Alpha (suspended) was detected at four of 39 groundwater locations.
The concentrations ranged from 3.2 to 4.3 pCi/L. Gross Beta (dissolved) was detected at 38 of 39 groundwater locations.
The concentrations ranged from 1.2 to 13.7 pCi/L. Gross Beta (suspended) was detected at six of 39 groundwater locations.
The concentrations ranged from 1.9 and 8.2 pCi/L.Hard-To-Detect analyses were performed on a select group of groundwater locations.
The analyses included Fe-55, Ni-63, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-234, U-235 and U-238. All hard-to-detect nuclides were not detected at concentrations greater than their respective MDCs.
II. Introduction The Three Mile Island Nuclear Station (TMINS) established a revised and more comprehensive groundwater monitoring program in 2006 as part of an Exelon Nuclear fleetwide assessment.
Conestoga Rovers & Associates (CRA) performed the initial assessment.
CRA prepared a Hydrogeologic Investigation Report (HIR) for Exelon to determine whether groundwater at and near TMINS has been adversely impacted by any releases of radionuclides.
The CRA report documents the results of the May 2006 Hydrogeologic Investigation Work Plan. CRA assessed groundwater quality at the Station and identified locations designated as Areas for Further Evaluation.
The results and conclusions of this Phase 1 study were made available to state and federal regulators, as well as the public on an Exelon web site for station specific reports.As a result of the Phase 1 study, the Radiological Groundwater Protection Program (RGPP) was revised to a long term monitoring program. This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Environmental Inc. (Midwest Labs) on well water, surface water, precipitation water and storm water samples collected in 2014. TMINS groundwater movement is into the Susquehanna River which surrounds the station on all sides.This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Environmental Inc. (Midwest Labs) on samples collected in 2014.A. Objective of the RGPP The long-term objectives of the Radiological Groundwater Protection Program (RGPP) are as follows: 1. Identify suitable locations to monitor and evaluate potential impacts from station operations before significant radiological impact to the environment and potential drinking water sources.2. Understand the local hydrogeologic regime in the vicinity of the station and maintain up-to-date knowledge of flow patterns on the surface and shallow subsurface.
- 3. Perform routine water sampling and radiological analysis of water from selected locations.
- 4. Notify stakeholders in a timely manner for new leaks, spills, or other detections with potential radiological significance.
- 5. Regularly assess analytical results to identify adverse trends.6. Take necessary corrective actions to protect groundwater resources.
B. Implementation of the Objectives The objectives identified have been implemented at Three Mile Island Nuclear Station as discussed below: 1. Three Mile Island Nuclear Station continues to sample and monitor the groundwater at the station in accordance with station procedures.
Sample frequencies and locations are adjusted based on monitoring results and investigations.
- 2. The Three Mile Island Nuclear Station reports describe the local hydrogeologic regime. Periodically, the flow patterns on the surface and shallow subsurface are updated based on ongoing measurements.
- 3. Three Mile Island Nuclear Station will continue to perform routine sampling and radiological analysis of water from selected locations.
- 4. Three Mile Island Nuclear Station has implemented procedures to identify and report leaks, spills, or other detections with potential radiological significance in a timely manner.5. Three Mile Island Nuclear Station staff and consulting hydrogeologist assess analytical results on an ongoing basis to identify adverse trends.C. Program Description
- 1. Sample Collection Sample locations can be found in Table A-1 and Figures A-1 and A-2, Appendix A.Groundwater, Surface Water, Storm Water, and Precipitation Samples of water are collected, managed, transported and analyzed in accordance with approved procedures.
Groundwater, surface water, storm water and precipitation are collected.
Sample locations, sample collection frequencies and analytical frequencies are controlled in accordance with approved station procedures.
Contractor and/or station personnel are trained in the collection, preservation management and shipment of samples, as well as in documentation of sampling events. For split samples, collectors will periodically collect samples that are sent to Midwest Labs to confirm that TBE is producing comparable data. Analytical laboratories are subject to internal quality assurance programs, industry cross-check programs, as well as nuclear industry audits.Station personnel review and evaluate all analytical data deliverables as data are received.Analytical data results are reviewed by both station personnel and an independent hydrogeologist for adverse trends or changes to hydrogeologic conditions.
D. Characteristics of Tritium (H-3)Tritium (chemical symbol H-3) is a radioactive isotope of hydrogen.
The most common form of tritium is tritium oxide, which is also called "tritiated water." Tritiated water behaves chemically and physically like non-tritiated water in the subsurface, and therefore tritiated water will travel at the same velocity as the average groundwater velocity.Tritium is created in the environment from naturally occurring processes both cosmic and subterranean, as well as from anthropogenic (i.e., man-made) sources. Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules.
This "cosmogenic" tritium combines with oxygen to form tritiated water, which will then enter the hydrologic cycle. Below ground, "lithogenic" tritium is produced by the bombardment of natural lithium present in crystalline rocks by neutrons produced by the radioactive decay of naturally abundant uranium and thorium. Lithogenic production of tritium is usually negligible compared to other sources due to the limited abundance of lithium in rock. The lithogenic tritium is introduced directly to groundwater.
A major anthropogenic source of tritium and strontium-90 comes from the former atmospheric testing of thermonuclear weapons. Levels of tritium in precipitation increased significantly during the 1950s and early 1960s and later with additional testing, resulting in the release of significant amounts of tritium to the atmosphere.
The Canadian heavy water nuclear power reactors, other commercial power reactors, nuclear research and weapons production continue to influence tritium concentrations in the environment.
The chemical properties of tritium are essentially those of ordinary hydrogen.
Tritium can be taken into the body by drinking water, breathing air, eating food, or absorption through skin. Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body.Tritium is excreted primarily through urine with a clearance rate characterized by an effective biological half-life of about 14 days. Within one month or so after ingestion, all tritium is essentially cleared.Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the body for a longer period.Tritium has a radiological half-life of approximately 12.3 years. It decays spontaneously to helium-3 (He-3). This radioactive decay releases a beta particle (low-energy electron).
The radioactive decay of tritium is the source of the health risk from exposure to tritium. Tritium is one of the least dangerous radionuclides, because it emits very weak radiation and leaves the body relatively quickly. Since tritium is almost always found as water, it goes directly into soft tissues and organs. The associated dose to these tissues is generally uniform and is dependent on the water content of the specific tissue.Ill. Program Description A. Sample Analysis This section describes the general analytical methodologies used by TBE and Midwest Labs to analyze the environmental samples for radioactivity for the Three Mile Island Nuclear Station RGPP in 2014.In order to achieve the stated objectives, the current program includes the following analyses: 1. Concentrations of gamma emitters in groundwater, surface water and storm water.2. Concentrations of strontium in groundwater.
- 3. Concentrations of tritium in groundwater, surface water, precipitation water and storm water.4. Concentrations of Am-241 in groundwater.
- 5. Concentrations of Cm-242 and Cm-243/244 in groundwater.
- 6. Concentrations of Pu-238 and PU-239/240 in groundwater.
- 8. Concentrations of Fe-55 in groundwater.
- 9. Concentrations of Ni-63 in groundwater.
- 10. Concentrations of Gross Alpha and Gross Beta (Dissolved and Suspended) in groundwater.
B. Data Interpretation
- 1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is specified by federal regulation as a minimum sensitivity value that must be achieved routinely by the analytical parameter.
- 2. Laboratory Measurements Uncertainty The estimated uncertainty in measurement of tritium in environmental samples is frequently on the order of 50% of the measurement value.Statistically, the exact value of a measurement is expressed as a range with a stated level of confidence.
The convention is to report results with a 95% level of confidence.
The uncertainty comes from calibration standards, sample volume or weight measurements, sampling uncertainty and other factors. Exelon reports the uncertainty of a measurement created by statistical process (counting error).Analytical uncertainties are reported at the 95% confidence level in this report for reporting consistency with the AREOR.Gamma spectroscopy results for each type of sample were grouped as follows: For groundwater, surface water, and storm water 13 nuclides, Be-7, K-40, Mn-54, Co-58, Fe-59, Co-60, Zn-65, Nb-95, Zr-95, Cs-134, Cs-137, Ba-140 and La-140 were reported.The radio-analytical laboratory is counting tritium results to an LLD of 200 pCi/L. Typically, the lowest positive measurement will be reported within a range of 40 -240 pCi/L or 140 +/- 100 pCi/L.Clearly, these sample results cannot be distinguished as different from background at this concentration.
IV. Results and Discussion A. Groundwater Results Samples were collected from on and off-site wells in accordance with the station radiological groundwater protection program.Analytical results and anomalies are discussed below.Tritium Samples from 60 locations were analyzed for tritium activity.
Tritium values ranged from the detection limit to 17,700 pCi/L (Table B-I.1, Appendix B).Tritium Split Samples Tritium values ranged from 186 to 8,916 pCi/L (Table C-1.1, Appendix C).Strontium Strontium-89 and strontium-90 were not detected above their required detection limit of 10 and 1.0 pCi/L, respectively (Table B-1.1, Appendix B).Strontium Split Samples Strontium-89 and Strontium-90 were not detected above the required detection limit (Table C-1.1, Appendix C).Gross Alpha and Gross Beta (dissolved and suspended)
Gross Alpha and Gross Beta analyses in the dissolved and suspended fractions were performed on groundwater samples during the second quarter sampling in 2014. Gross Alpha (dissolved) was not detected at any of the 39 groundwater locations.
Gross Alpha (suspended) was detected at four of 39 groundwater locations.
The concentrations ranged from 3.2 to 4.3 pCi/L. Gross Beta (dissolved) was detected at 38 of 39 groundwater locations.
The concentrations ranged from 1.2 to 13.7 pCi/L. Gross Beta (suspended) was detected at six of 39 groundwater locations.
The concentrations were 1.9 and 8.2 pCi/L (Table B-1.1, Appendix B).
Gross Alpha and Gross Beta Split Samples Two split samples were analyzed for Gross Alpha and Gross Beta in 2014. Gross Alpha was not detected at either groundwater location.
Gross beta was detected in both samples analyzed.

Surface Water Results Samples were collected from surface water locations in accordance with the station radiological groundwater protection program.Analytical results and anomalies are discussed below.Tritium Three locations were analyzed for tritium in 2014. Tritium was not detected above the required detection limit of 200 pCi/L in any of the 13 samples analyzed (Table B-11.1, Appendix B).Tritium Split Samples One location was analyzed for tritium in 2014. Tritium was not detected above the required detection limit (Table C-I1.1, Appendix C).Strontium Surface water samples were not analyzed for Sr-90 in 2014 (Table B-II.1, Appendix B).Gamma Emitters Three locations were analyzed for gamma-emitting nuclides in 2014. None of the four samples detected gamma-emitting nuclides (Table B-1I.2, Appendix B).Gamma Emitters Split Samples One location was analyzed for gamma-emitting nuclides in 2014.No gamma emitting nuclides were detected (Table C-11.2, Appendix C).C. Storm Water Results Samples were collected from storm water locations in accordance with the station radiological groundwater protection program.Analytical results and anomalies are discussed below.Tritium One location was analyzed for tritium. Tritium was detected in two of samples above the required detection limit of 200 pCi/L. The concentration ranged from 289 to 312 pCi/L (Table B-Ill.1, Appendix B).Gamma Emitters Samples from one location were analyzed for gamma-emitting nuclides.
No gamma emitting nuclides were detected (Table B-Ill.2, Appendix B).
D. Precipitation Water Results Samples were collected at four locations.
The following analyses were performed:
Tritium Samples from five locations were analyzed for tritium activity.
Tritium activity was detected at three of four locations.
The concentrations ranged from 246 to 2,470 pCi/L (Table B-IV.1, Appendix B).Tritium Split Samples Samples from one location were analyzed for tritium activity.
Tritium activity was detected in three of four samples. The concentrations ranged from 246 to 2,350 pCi/L (Table C-111.1, Appendix C).Gamma Emitters Precipitation water was not analyzed for Gamma Emitters in 2014.Gamma Emitters Split Samples No gamma-emitting nuclides were analyzed in 2014.E. Leaks, Spills, and Releases A potential leak was identified at TMI in 2012 due to elevated MS-22 tritium concentration readings.
TMI continues to monitor MS-22 and surrounding wells, in addition to tritium plumes from previous years, and reports the activity and dose to the public in the ARERR. The elevated MS-22 well tritium concentrations were voluntarily reported under the reporting requirements for the NEI Groundwater Protection Initiative (GPI)as implemented in Exelon's Reportability procedure LS-AA-1 120, RAD 1.34 ( IR 1385497/1515261)
As reported previously a number of potential sources were mitigated in 2013. The Borated Water Storage Tank (BWST) tunnel sump was cleaned and repaired.
An active input to the BWST tunnel sump (packing leak-off of a BWST isolation valve) was corrected.
A tank leak on CST B and a leaking buried pipe flange were repaired, and BS-T-1 & 2 and ancillary piping were drained and emptied.In June 2014 an inspection of the BWST external connections revealed that a 24 inch flange was found coated in boron deposits indicating leakage. The flange was cleaned and the boron deposits removed. The repair of the flange is scheduled during TMI's refueling outage in the Fall of 2015. In December 2014, a follow-up inspection showed additional boron deposits.
In January 2015, an enclosure with a catch containment was installed to help in preventing the small amounts of leakage from migrating to the environment.
F. Actions Taken 1. Compensatory Actions In 2013, TMI installed eight new wells to help isolate and investigate the area of the leak. TMI has an extensive groundwater monitoring program with over 50 monitoring wells. No monitoring wells outside the investigation area have seen elevated tritium concentrations.
TMI continues to monitor the BWST area wells closely. The leakage has been mitigated by preventing rain/snow from entering the area of concern and by placement of a catch containment for any moisture that might accumulate.
The containment is inspected regularly, and the permanent flange repair is scheduled during TMI's next refueling outage in Fall 2015.
