Introduction PBAPS is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Township, York County, Pennsylvania. PBAPS Units 2 and 3 are boiling water reactors, each with a rated full-power output of approximately 4,016 MWth while Unit 1 is a decommissioned 115 MWth High Temperature, Gas-cooled Reactor (HTGR). The initial environmental monitoring program began 5 February 1966.
A summary of the Unit 1 preoperational monitoring program was presented in a previous report <1l. Preoperational summary reports <2,3l for Units 2 and 3 have been previously issued and summarize the results of all analyses performed on samples collected from 5 February 1966 through 8 August 1973.
The sampling and analysis requirements are contained in the PBAPS ODCM and the ODCM Specifications (ODCMS). This AREOR covers those analyses performed by
. Teledyne Brown Engineering (TBE), Landauer, Exelon Industrial Services (EIS) and GEL Laboratories on samples collected during the period 01 January 2018 through 31 December 2018.
A Objectives The objectives of the REMP are:
- 1.
Provide data on measurable levels of radiation and radioactive materials in the publicly-used environs;
- 2.
Evaluate the principal pathways of exposure to the public as described in the ODCM and determine the relationship between quantities of radioactive material released from the plant and resultant radiation doses to members of the public.
B.
Implementation of the Objectives 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 plant operation to assess station radiological effects (if any) on man and the environment.
As the REMP is established to measure the impact of power plant operations (release of radionuclides) on man and the environment; it is important to understand radiation/radioactivity, the units used to measure them, and natural sources of radiation in the environment. A brief explanation is provided to differentiate between radiation from nuclear power production and other sources, be they man-made or natural. The doses produced from the other sources of radiation can be compared to the data presented in this report.
measurements were 8.8 +/- 2.6 mR/standard month, consistent with those measured in previous years, indicating that the Independent Spent Fuel Storage Installation (ISFSI) had no measurable impact to the environs.
In.2018, the doses from both liquid and gaseous effluents were conservatively calculated for the Maximum Exposed Member of the Public due to PBAPS Operation. Doses calculated were well below all Offsite Dose Calculations Manual (ODCM) limits. The results of those calculations were as follows:

C.
Radiation and Radioactivity All matter is made of atoms. An atom is the smallest part into which matter can be broken down and still maintain all its chemical properties. Nuclear radiation is energy, in the form of waves or particles that is given off by unstable, radioactive atoms. Radioactive material exists naturally and has always been a part of our environment. The earth's crust, for example, contains radioactive uranium, radium, thorium and potassium. Some radioactivity is a result of nuclear weapons testing. Examples of radioactive fallout that is normally present.in environmental samples are Cs-137 and Strontium-90 (Sr-90). Some examples of radioactive materials released from a nuclear power plant are Cs-137, 1-131, Sr-90 and Cobalt-60 (Co-60).
Radiation is measured in units of millirem; much like temperature is measured in degrees. A millirem is a measure of the biological effect of the energy deposited in tissue. The natural and man-made radiation dose received in one year by the average American is 300 to 400 mrem (References 5, 6, 7 in Table 1 below).
Radioactivity is measured in curies. A curie is that amount of radioactive
. material needed to produce 3.70E+10 nuclear disintegrations per second. This is an extremely large amount of radioactivity in comparison to environmental radioactivity. That is why radioactivity in the environment is measured in picocuries. One picocurie is equal to 1.00E-12 (one trillionth) of a curie.
D. Sources of Radiation As mentioned previously, naturally occurring radioactivity has always been a part of our environment. Table I shows the typical doses received from natural and man-made sources.

<1 Nuclear Power Plants
<1 Approximate Total 311 Approximate Total 314 Cosmic radiation froin the sun and outer space penetrates the earth's atmosphere and continuously bombards us with rays and charged particles.
Some of this cosmic radiation interacts with gases and particles in the atmosphere, making them radioactive in turn. These radioactive byproducts from cosmic ray bombardment are referred to as cosmogenic radionuclides.
Isotopes such as Beryllium-7 (Be-7) and Carbon-14 (C-14) are formed in this way. Exposure to cosmic and cosmogenic sources of radioactivity results in a dose of 33 mrem per year.
Additionally, natural radioactivity is in our body, in the food we eat (about 29 millirem/yr), in the ground we walk on (about 21 millirem/yr), and in the air we breathe (about 228 millirem/yr). One percent of all potassium in nature is the radioactive Potassium-40 (K-40). The majority of a person's annual dose results from exposure to radon and thoron in the air we breathe. These gases and their radioactive decay products arise from the decay of naturally occurring uranium, thorium and radium in soil and in building products such as brick, stone and concrete. Radon and thoron levels vary greatly with location, primarily due to changes in the concentration of uranium and thorium in the soil. Residents at some locations in Colorado, New York, Pennsylvania, and New Jersey have a higher annual dose as a result of higher levels of radon/thoron gases in these areas. In total, these various sources of naturally occurring radiation and radioactivity contribute to a total dose of about 311 mrem per year.
In addition to natural radiation, we are normally exposed to radiation from a number of man-made sources. The single largest dose from man-made sources result from therapeutic and diagnostic applications of x-rays and radiopharmaceuticals. The annual dose to an individual in the U.S. from medical and dental exposure is about 300 mrem. Consumer products, such as televisions and smoke detectors, contribute about 13 mrem/yr. Much smaller doses result from weapons fallout and nuclear power plants (less than 1 mrem/yr). Typically, the average person in the United States receives about 314 mrem per year from man-made sources.
Some of the natural radioactive nuclides discussed above were identified in PBAPS REMP samples. The typical power production radionuclides, describ1:1d in the next sections, were not identified and thus it can be concluded that PBAPS did not impact man and the' environs during the 2018 operating period.

Program Description A.
Sample Collection Exelon Industrial Services (EIS) collected samples for the REMP for PBAPS Exelon Nuclear. This section describes the collection methods used by EIS to obtain environmental samples for the PBAPS REMP in 2018. Sample locations and descriptions can be found in Table B-1 and Figures B-1 through B-3, Appendix B. The collection procedures used by EIS are listed in Table B-2, Appendix B.
Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of surface water, drinking water, fish and sediment. Surface water is sampled from two locations as prescribed by the ODCM: one upstream (1 LL) and one downstream (1 MM) of the plant discharge canal. Drinking water is sampled from a control location (61) and up to 3 locations nearest to public drinking water supplies. Two locations are identified in the ODCM as the closest drinking water supplies, the Conowingo Dam (4L) and Chester Water Authority (138). All samples were collected weekly by automatic sampling equipment or as grab samples. Weekly samples from each location were composited into two one-gallon monthly samples for analysis. A separate quarterly composite of the monthly samples was also collected.
Fish sample collection locations required by the ODCM are in an area close to the discharge of PBAPS (4) and a control location, unaffected by plant discharge (6).
These samples were comprised of the flesh of commercially and recreationally important species specific to the environs around PBAPS. Fish samples were
. collected semiannually from two groups: Bottom Feeder (channel catfish, flathead catfish, and carp) and Predator (smallmouth and largemouth bass), as these are the types of fish commonly collected by the public from the river around PBAPS.
The total weight of fish flesh was approximately 1000 grams. The samples were preserved on ice for shipping to the laboratory.
The ODCM requires one sediment sample to be collected downstream of the plant in an area with existing or potential recreational value. The REMP collects samples from three locations (4J, 4T and 6F; 6F is the control). Sediment samples, composed of recently deposited substrate, were collected semiannually.
Multiple grab samples of the sediment were collected to obtain an approximately homogenous, representative sample totaling 1000 grams.
Terrestrial Environment The terrestrial environment was evaluated by performing radiological analyses on milk and food product samples. The ODCM requires milk samples at three locations with the highest dose potential, within three miles of PBAPS and one sample at a control location. The REMP meets these requirements and samples extra locations. Milk samples were collected biweekly at five locations (J, R, S, U, X and V; V is the control) from April through November, when the cows were on pasture, and monthly from December through March, when the cows were primarily on feed. Six additional locations (C, D, E, L, P and W; C and E are the controls) were sampled quarterly. Two-gallon samples were collected directly from the bulk tank at each location, preserved with sodium bisulfite, and shipped promptly to the laboratory.
The ODCM requires food products to be collected from the area of highest dose impact and a control location, if milk sampling is unavailable in those locations.
Milk sampling occurs in most every sector, but one, and a garden was established there for sampling. Food product samples, comprised of annual broad green leaf vegetation, were collected monthly at four locations (1 C, 20, 3Q and 55; 55 is the control) from June through September. Typically, the 'planting' season starts late April/early May, with the plants gaining sufficient mass for collection in late June or July. Approximately 1000 g of unwashed samples were collected in plastic bags and shipped promptly to the laboratory, but sample size varied on garden production.
Airborne Environment The airborne atmospheric environment was evaluated by performing radiological analyses on air particulate and radioiodine samples. The ODCM requires sampling from five locations, including three site boundary locations with greatest dose impact, one location within a local community with the highest dose impact, and one control location. Air particulate and radioiodine samples were collected and analyzed weekly from five locations (1 B, 1C, 1Z/1A, 3A and 5H2; 5H2 is the control, 1A is the duplicate QA location). Airborne iodine and particulate samples were obtained at each location using a vacuum pump to pull air through a glass fiber filter and charcoal cartridge. The pumps were run continuously and sampled air at the rate of approximately 1 cubic foot per minute to obtain a minimum total volume of 280 cubic meters. The weekly filters were composited for a quarterly sample.
Ambient Gamma Radiation The ambient gamma radiation in the areas surrounding PBAPS is measured using dosimeters, which are exposed to ambient radiation in the field and exchanged quarterly. The ODCM requires at least 40 routine monitoring stations with two or more dosimeters at each location for continuous monitoring.
The REMP contains 48 dosimeter monitoring locations.
Optically-Stimulated Luminescent Dosimeters (OSLO) replaced the Thermo-Luminescent Dosimeter (TLD) starting in 2012. However, PBAPS continued using TLD in addition to OSLO to compare the two technologies. The primary data reported after 2012 is from OSLO. Additionally, only the "gross" OSLO exposure (i.e. no background or control subtraction) is reported; prior to 2012, "net' TLD exposures data were reported. This explains the increase in ambient radiation levels displayed in Figure C-6.
The OSLO locations were placed on and around the P8APS site as follows:
Site boundary monitoring consists of 19 locations (1A, 18, 1 C, 1 D, 1 E, 1 F, 1 G, 1 H, 11, 1 J, 1 K, 1 L, 1 M, 1 NN, 1 P, 1 Q, 1 R, 2, and 40), 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).
Intermediate distance monitoring consists of 23 locations (14, 15, 17, 22, 23, 26, 27, 31A, 32, 3A, 42, 43, 44, 45, 46, 47, 48, 49, 4K, 5, 50, 51 and 68), extending to approximately 5 miles from the site and designed to measure possible exposures to close-in population.
Six locations (16, 18, 19, 24, 28 and 1T) represent control and special interests areas such as population centers, schools, and nearest residents.
The specific dosimeter locations were determined by the following criteria:
- 1. The presence of relatively dense population, nearby residences, schools, and control locations;
- 2. Site meteorological data taking into account distance and elevation for each of the sixteen 22.5 degree sectors around the site, where estimated annual dose from P8APS, if any, would be more significant;
- 3. And on hills free from local obstructions and within sight of the vents (where practical).
Each dosimetry location in the environment has 2 OSLO and 2 TLD dosimeters which were enclosed in plastic as a moisture barrier. Dosimeter housing are mesh plastic tubes, aligned horizontally and oriented such that dosimeter windows face the plant. Dosimeters themselves were placed vertically in the tubes so that no dosimeter was covered by another dosimeter and all dosimeters properly faced the plant.
8.* Sample Analysis This section describes the analytical methods used by T8E, EIS and GEL Labs to analyze the environmental samples for radioactivity. The analytical procedures used by the laboratories are listed in Table 8-2, Appendix 8.
The required OCDM analyses include:
- 1. Concentrations of beta emitters in drinking water and air particulates;
- 2. Concentrations of gamma-emitting nuclides in surface and drinking water, air particulates, milk, fish, sediment and food products;
- 3. Concentrations of tritium in surface and drinking water;
- 4. Concentrations of 1-131 in air, milk, and food products. Although not required by the ODCM, 1-131 is also analyzed in drinking and surface water;
- 5. Ambient gamma radiation levels at various site environs.
C. Data Interpretation The radiological environmental and direct radiation data collected prior to PBAPS becoming operational was used as a baseline with which the 2018 operational data were compared. In addition, data were compared to previous years' operational data for consistency and trending. Several factors are important in the interpretation of the data.
- 1. Lower Limit of Detection and Minimum Detectable Concentration The lower limit of detection (LLD) is 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 is intended as a "before-the-fact" (a prion) estimate of a system (including instrumentation, procedure and sample type) and not as an "after-the-fact" (a posterior,) measurement. All analyses are designed to achieve the required detection limits for environmental samples, as described in the PBAPS ODCM.
The minimum detectable concentration or activity (MDC or MDA) is defined as the "after-the-fact" (a posterior,) estimate determined during the analysis of the sample.
- 2. Net Activity Calculation and Reporting of Results Net activity for a sample is calculated by subtracting background activity from the sample activity. Since the REMP measures extremely small changes in radioactivity in the environment, background variations can result in sample activity being lower than the background activity causing a negative number.
MDC is reported in all cases where positive activity was not detected. In previous years, when net activity was reported, a lower baseline is seen in trending when compared to 2018 results.
Gamma spectroscopy results for each type of sample were grouped as follows:
For surface and drinking water, twelve nuclides, Manganese-54 (Mn-54),
Cobalt-58 (Co-58), lron-59 (Fe-59), Cobalt-60 (Co-60), Zinc-65 (Zn-65),
Zirconium-95 (Zr-95), Niobium-95 (Nb-95), 1-131, Cesium-134 (Cs-134),
Cs-137, Barium-140 (Ba-140), and Lanthanum-140 (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, seven nuclides, K-40, Mn-54, Co-58, Co-60, 1-131, Cs-134 and Cs-137 were reported.
For air particulates, six nuclides, Be-7, Mn-54, Co-58, Co-60, Cs-134 and Cs-137 were reported.
For milk, six nuclides, K-40, 1-131, Cs-134, Cs-137, Ba-140 and La-140 were reported.
For food products, eight nuclides, Be-7, K-40, Mn-54, Co-58, Co-60, 1-131, Cs-134 and Cs-137 were reported.
Positive activity values (greater than MDC) were recorded and the mean and
- two standard deviation of the results were calculated. The standard deviation represents the variability of measured results for different samples of the same media rather than a single analysis uncertainty.
D. Program Exceptions For 2018, the PBAPS REMP had a sample collection recovery rate of> 99%.

- APIA/ = Air Parliculates/Air Iodine For the two weeks that location 5H2 missed air samples (IR# 2701975-03-01) the results from a co-located Limerick air sampling station were reviewed. These results did not show any abnormal results of concern; therefore, these missed samples are an acceptable deviation. 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 a recurrence.
Occasional equipment breakdowns and power outages were unavoidable.
Equipment with electrical issues were returned to manufacturer for repair or replacement.
IV.
Program Changes In 2018, PB upgraded the REMP air sampling equipment. Two restricted flow orifice pumps and four Hi-Q VS23 constant flow air sampler with gas totalizing meter and timer were replaced with Radeco AVS-28A portable constant air flow sampler with timer. This was done to improve equipment reliability. Also the sampling hoses and shrouds were replaced. The old shrouds were bell shaped and havens for wasps' nests. The new shrouds are more ring shaped and open and eliminated this environmental safety hazard.
V.
Results and Discussion Appendix A contains a summary of all 2018 PBAPS REMP results which meets the requirement of Table 3 of NU REG 1302 'Branch Technical Position Paper'9. Table A-1 lists results by each sample media and analyses performed. The total number of analyses performed, required LLD, the number of positive results for each indicator and control location are also listed. From the positive results identified (greater than the MDA) the mean value, range and station locations with highest annual mean are listed.
Commonly identified nuclides are gross beta, K-40, and Be-7. A graphical representation is provided in Figure A-1.
A.
Aquatic Environment
- 1. Surface Water A summary of the 2018 analysis results for surface water samples from stations 1 LL and 1 MM are listed below:
Tritium Quarterly samples were analyzed for tritium activity (Table C-1.1, Appendix C). No tritium activity was detected and the required LLD was met.
Iodine Monthly samples were analyzed for low level 1-131. All results were less than the MDC and the required LLD was met. (Table C-1.2, Appendix C).
Gamma Spectrometry Monthly samples were analyzed for gamma-emitting nuclides (Table C-1.3, Appendix C). All nuclides were less than the MDC and all required LLDs were met.
- 2. Drinking Water The results from the drinking water samples collected in 2018 from stations 138, 4L and 61 are described below:
Gross Beta Samples from all locations were analyzed monthly for concentrations of gross beta activity (Table C-11.1 and Figure C-1 Appendix C). Gross beta activity was detected in 18 of 36 samples. The values ranged from 1.8 to 4.0 pCi/L with a mean value of 2. 7 +/- 1.4 pCi/L. The mean detected gross beta activity was less than the required LLD (4 pCi/L) which indicates the sensitivity of the measurement technique. The detectable gross beta activity was well below the procedural investigation level (15 pCi/L). Concentrations detected were generally below those detected in previous years. (
Tritium Monthly samples were composited quarterly and analyzed for tritium activity (Table C-11.2, Appendix C). Tritium activity was not detected in any samples and the required LLD was met.
Iodine Monthly samples were analyzed for low level 1-131 (Table C-11.3, Appendix C). All results were less than the MDC and the required LLD was met.
Gamma Spectrometry Samples from the three locations were analyzed monthly for gamma-emitting nuclides (Table C-11.4, Appendix C). All nuclides were less than the MDC and all required LLDs were met.
- 3. Fish Results from fish samples collected at locations 4 and 6 in 2018 are described below:
Gamma Spectrometry The edible portions of the collected fish samples were analyzed semiannually for gamma-emitting nuclides (Table C-111.1, Appendix C). Naturally occurring K-40 was found at all stations and ranged from 3,034 to 4,107 pCi/kg (wet),
with a mean value of 3,620 +/- 770 pCi/kg (wet), consistent with levels detected in previous years. No fission or activation products, due to plant operations were found in 2018 and all required LLDs were met. Figure C-2, Appendix C, displays the various gamma radionuclide MDC results for locations 4 and 6, based on the type of fish collected. All MDC results are less than the.nuclide specific LLDs. The last 15-year average Cs-137 MDC is also shown to trend 2018 results with historical results. There have been no detectable levels of Cs-137 in fish since 1983.
- 4. Sediment Sediment samples were collected at locations 6F, 4J, and 4T and the results are described below:
Gamma Spectrometry Sediment samples were analyzed for gamma-emitting nuclides (Table C-IV.1, Appendix C). K-40 was found in all locations and ranged from 10,070 to 24,360 pCi/kg (dry) with a mean value of 16,675 +/- 10,196 pCi/kg (dry). The fission product Cs-137 was detected in 1 of the 6 samples at a concentration of 158 pCi/kg +/- 103 (dry), which is below the required LLD of 180 pCi/kg (dry). The positive result was also significantly less than the procedural investigation level of 1000 pCi/kg (dry), (IR #02701975-03-03).
2018 Cs-137 results are plotted against the average value from the last 15 years (Figure C-3, Appendix C). All values are significantly below the reporting level and there was not enough Cs-137 to indicate that the positive sample result was a consequence of plant operation. No other fission or activation products were found and all LLDs were met.
B.
Atmospheric Environment
- 1. Airborne Particulates Continuous air particulate samples were collected from five locations. The five locations were separated into three groups: Group I represents locations within the PBAPS site boundary (1 B, 1C and 1Z/1A), Group II represents the location of the closest local community (3A) and Group 111 represents the control location ata remote distance from PBAPS (5H2). 1A results are discussed in Section H. The results from samples collected in 2018 are described below:
Gross Beta Weekly samples were analyzed for concentrations of beta-emitters (Tables C-V.1, Appendix C). Detectable gross beta activity was observed at all locations. The results from Group I ranged from 6E-3 to 32E-3 pCi/m3, with a mean of 14E-3 +/- 1 OE-3 pCi/m3. The results from Group II ranged from 6E-3 to 28E-3 pCi/m3 with a mean of 14E-3 +/- 10E-3 pCi/m3. The results from the Group Ill ranged from 6E-3 to 28E-3 pCi/m3 with a mean of 13E-3 +/- 9E-3 pCi/m3.
The mean value from all locations are the same within error, indicating the gross beta activity is not a result of the operation of PBAPS, as shown in Figure C-4, Appendix C. In addition, a comparison of the 2018 air particulate data with historical data indicates a decreasing trend in gross beta activity since initial operation of the plant (Figure C-4, Appendix C).
Gamma Spectrometry Quarterly samples were analyzed for gamma-emitting nuclides (Table C-V.2, Appendix C). Naturally-occurring Be-7 activity, from cosmic rays, was detected in all 20 samples. The values ranged from 43E-3 to 90E-3 pCi/m3, with a mean value of 66E-3 +/- 30E-3pCi/m3* All power production nuclides were less than the MDC and all required LLDs were met.
- 2. Airborne Iodine Weekly samples were also analyzed for low level 1-131 (Table C-Vl.1, Appendix C). All results were less than the MDC for 1-131 and the required LLD was met.
C.
Terrestrial
- 1. Milk During 2018, 156 milk samples were collected and analyzed from the following locations: D, J, R, L, P, S, U, W, X (indicators) and C, E, V (controls). The results are described below:
lodine-131 Milk samples from all locations were analyzed for concentrations of 1-131 (Tables C-Vll.1, Appendix C). All results were less than the MDC for 1-131 and all required LLDs were met. Figure C-5 displays the 2018 milk 1-131 results for both indicator and control locations. All results are less than the LLD (1 pCi/L) and much less than the reporting level (3 pCi/L).
Gamma Spectrometry Milk samples from all locations were analyzed for concentrations of gamma-emitting nuclides (Table C-Vll.2, Appendix C). Naturally-occurring K-40 was found in all samples and ranged from 947 to 2, 129 pCi/1, with a mean value of 1262 +/- 283 pCi/L. All other nuclides were less than the MDC and all required LLDs were met.
2018 Cs-134 and Cs-137 MDC results are plotted in Figure C-5 with the required LLDs and Reporting Levels. All results are much less than the LLDs and reporting levels. The last 15-year average MDC of Cs-137 in milk is also plotted in Figure C-5, Appendix C. There is no statistical difference between the 2018 MDC Cs-137 results and the 15-year historical MDC.
- 2.
Food Products Throughout 2018, 47 samples of various green leafy vegetation (kale, cabbage, collard greens, broccoli, etc.) were collected and analyzed for concentrations of gamma-emitting nuclides (Table C-Vlll.1, Appendix C). The results are discussed below:
Gamma Spectrometry Naturally-occurring Be-7 activity was found in 33 of 47 samples and ranged from 262 to 26,950 pCi/kg (wet), with a mean of 2,062 +/- 9,620 pCi/kg (wet).
Also, naturally occurring K-40 activity was found in all samples and ranged from 905 to 9,595 pCi/kg (wet), with a mean of 3,845 +/- 3,527 pCi/kg (wet). All power production nuclides were less than the MDC and all required LLDs were met.
D.
Ambient Gamma Radiation Results of OSLO measurements are listed in Tables C-IX.1 and C-IX.2 and Figure C-6, Appendix C.
The mean gross OSLO measurement for all indicator locations was 8.8 +/- 2.6 mRem per standard month, with a range of 5.5 to 12.9 mRem per standard month.
The period mean for the control locations (16, 18, 19 and 24) was 8.1 +/- 2.1 mRem per standard month, with a range of 6.5 to 9.5 mRem per standard month, which is the same as the OSLDs located within the site boundary and intermediate distances. These results indicate P8APS operation had no impact on the ambient gamma radiation levels in the areas surrounding P8APS. This trend has occurred throughout the history of the plant and can be seen in Figure C-6, Appendix C.
The 2012 increase in ambient radiation reading in 2012, seen in Figure C-6, was due to the change from TLD to OSLO monitoring and the reporting of gross rather than net measurement values.
E.
Independent Spent Fuel Storage Installation (ISFSI)
ISFSI was initiated in June 2000. Six new casks were added to the ISFSI pad in 2018. Site boundary OSLDs which measure the ambient gamma radiation closest to ISFSI are locations 1A, 1 D, 1 M, 1 P, 1 Q, 1 R, with 1 R being the closest.
Location 28 is the nearest real resident which could be impacted by ISFSI.
Location 1 R, showed a general increase of 1 to 3 mRem per standard month from pre-lSFSI loading (Figure C-7, Appendix C). Location 28, follows closely with values from locations 1A, 1 D, and controls, indicating no impact from ISFSI on nearest real resident. Data from location 28 is used to demonstrate compliance to both 40CFR 190 and 10CFR72.104 limits. All radiation levels are well below regulatory limits.
The pre-operational (pre-op) ambient gamma radiation level is not a gross value, therefore, Figure C-7 displays a 'Pre-Op + Transit' value which adds an average transit dose to the pre-op value. Transit dose is any dose recorded by the OSLDs when they are not actively measuring ambient radiation in the field (e.g.
during transportation and dosimeter change outs). Transit dose can be measured anywhere from 3 to 8 mrem per month. An average value of 5 mrem per month was added to show that even though an increased dose is observed due to ISFSI operations, ISFSI is not increasing ambient gamma radiation levels above background and pre-operation levels. Location 1 R is approaching the pre-operational levels, but the other locations around ISFSI are still well below background levels.
The dosimetry system is undergoing an evaluation to align with the new methodology presented in ANSI 13.37, "Environmental Dosimetry".(10l This methodology is included in part of a revision to Regulatory Guide 4.13 (Draft Regulatory Guide DG-4019, "Environmental Dosimetry - Performance, Specifications, Testing, and Data Analysis").(11l The dosimetry results will be presented in the new methodology starting in 2019.
F.
Land Use Census A Land Use Survey, conducted during the fall of 2018, was performed by Exelon Industrial Services (EIS), to comply with Section 3.8.E.2 of PBAPS's ODCM Specifications. The survey documented the nearest milk-producing and meat animal, nearest residence, and garden larger than 500 square feet in each of the sixteen meteorological sectors out to five miles.
Also, because PBAPS is an elevated release facility, an additional requirement of identifying all gardens larger than 500 square feet and every dairy operation within three (3) miles was included in the survey. The distance and direction of all locations were positioned using Global Positioning System (GPS) technology. The results of this survey are summarized below.
There was no change in nearest residents compared to the 2017 report. There were gardens identified in all sectors except the NNW sector. Four (4) new gardens were located this year in SSE, SSW, WSW and W sectors. The garden in sector SSW was identified as the closest garden for that sector. Animals used for meat consumption were identified in 14 of the 16 sectors. Five new sites were identified this year in WNW, WSW, W, and E sectors, with the nearest meat animal updating in the WSW sector. Dairy sites were identified in 12 of 16 sectors with no changes in nearest milk-producing animal in any sector.

Errata Data In the 2017 AREOR, the location for Milk Farm C was incorrect in Table B-1, Appendix B (IR #04174541). Table B-1 has been incorrect since 2011 (the AREOR for 2010) when the units in that table changed from miles to feet.
Review of previous AREORs identified that Milk Farm C was never included on a map until the 2017 AREOR. The distance is 9.54 miles or 50,400 ft.
The corrected table is shown in Appendix F.
H.
Secondary Laboratory Analysis Appendix D of this report presents the results of data analyses performed by the QC laboratory, EIS and GEL. Duplicate samples were obtained from several locations and analyzed by both the primary and QC laboratories.
GEL was only used for H-3 analyses of water samples because EIS could not perform those analyses. Comparisons of the results for all media were within expected ranges.
Figure D-2 shows the gross beta results for both TBE and EIS. These.
samples are from two separate air samplers co-located within a few feet of each other, but there is a distinct bias. Limerick Generating Station noticed similar results with their duplicate samples and performed in investigation tracked under IR# 4048258-02. During that investigation it was verified that each lab has passed their crosscheck program blind sample analyses. The only difference between each lab's calibration and sample analyses identified at this time is the sample count time. There does appear to be a slight low bias for TBE compared to EIS but based on cross check results the bias appears to be negligible compared to actual sample results. The fact that the samples being compared are not the same samples but different samples from the same location adds to the potential differences in reported values.
The results between the labs do appear to trend together though with the slight bias identified.
In December of 2018, there were elevated gross beta results for 1A that were not seen in the 1 Z filter. EIS did investigate by recounting samples and swapping the sample pumps, but not until over a month past sample collection. The filter deposition was noticeably darker than previous weeks, but sample results returned to normal ranges within the next month. No reportable or investigation limits were exceeded with the elevated results.
There was no detectable gamma activity on the quarterly filter, therefore, these results were not a concern.
I.
Summary of Results - Quality Control (QC) Laboratory Analysis The primary and secondary laboratories analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, food products and water matrices (Appendix E). The PE samples, supplied by Eckert & Ziegler Analytics, Inc., Environmental Resource Associates (ERA) and DOE's Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against a pre-set acceptance criteria described in Appendix E.
For the Teledyne Brown Engineering (TBE) laboratory, 166 out of 172 analyses performed met the specified acceptance criteria. Six analyses (Water - Sr-90, Milk - Fe-59 & 1-131, Vegetation - Sr-90 (2) and Soil - Cr-51) did not meet the specified acceptance criteria and are documented in Appendix E. TBE has addressed each issue through the TBE Corrective Action Program.
For the EIS laboratory, 63 of 63 analyses met the specified acceptance criteria.
For the GEL laboratory, For the GEL laboratory, 345 of 352 analyses met the specified acceptance criteria. Tritium (water matrix) was the only nuclide analyzed for Peach Bottom REMP and all analyses met the specified acceptance criteria. Nuclides analyzed for Peach Bottom RGPP included H-3, Sr-89/90, Gross Alpha, Gross Beta, Gamma, and Alpha Spec (water matrix). One nuclide, Uranium did not meet the specified acceptance criteria and is documented in Appendix F. All failures were addressed through GEL's Corrective Action Program.
The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

APPENDIX E ERRATA DATA
Intentionally left blank
An error was found in the 2017 AREOR. Milk Farm C location in Appendix B is incorrect and has been incorrect since 2011 (AEROR for 2010), when units changed from miles to feet. Review of previous AREORs identified that Milk Farm C was never included on a map until the 2017 AEROR. The distance is 9.54 miles or 50,400 ft. (IR 04174541).

APPENDIX F INTER-LABORATORY COMPARISON PROGRAM ACCEPTANCE CRITERIA AND RESULTS
Intentionally left blank
A. Pre-set Acceptance Criteria
- 1.
Analytics Evaluation Criteria Analytics' evaluation report provides a ratio of laboratory results 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 The Environmental Resource Associates' evaluation report provides an acceptance range for control and warning limits with associated flag values.
The Environmental Resource Associates' acceptance limits are established per the United States Environmental Protection Agency (USEPA), National Environmental Laboratory Accreditation Conference (NELAC), state-specific performance testing program requirements or ERA's standard operating procedure 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.
Note: The Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) samples are created to mimic conditions found at DOE sites which do not resemble typical environmental samples obtained at commercial nuclear power facilities.
B. TBE PE Results and Discussion
- 1.
TBE was unable to report the February 2018 DOE MAPEP vegetation Sr-90 result due to QC failure and limited sample amount. (NCR 18-09)
- 2.
The Analytics September 2018 milk Fe-59 result was evaluated as Not Acceptable (Ratio of TBE to known result at 132%). The reported value was 158 +/- 17.6 pCi/L and the known*value was 119 +/- 19.9 pCi/L. No cause for the failure could be determined. TBE has passed 24 of the previous 27 milk cross-check results since 2012. This sample was run in duplicate on a different detector with comparable results (162 +/- 16 pCi/L). NOTE: TBE's 4'h Qtr result passed at 105% (NCR 18-20)
- 3.
The Analytics September milk 1-131 result was evaluated as Not Acceptable (Ratio of TBE to known result at 143%). Due to a personnel change in the gamma prep lab, the sample was not prepped/counted in a timely manner such as to accommodate the 1-131 8-day half-life. Analysts have been made aware of the urgency for this analysis and it will be monitored more closely by QA (NCR 18-24)
NOTE: TBE's 4'h Qtr result passed at 101%
- 4.
The Analytics September soil Cr-51 result was evaluated as Not Acceptable (Ratio of TBE to known result at 131 %). As with #3 above, the sample was not prepped/counted in a timely manner such as to accommodate the Cr-51 27-day half-life. The same corrective action applies here as in #3. (NCR 18-21)
- 5.
The MAPEP November vegetation Sr-90 result of 0.338 Sq/sample was evaluated as Not Acceptable (Lower acceptable range was 0.554 Sq/sample).
It appears that there has been incomplete dissolution of Sr-90 due to the composition of the MAPEP vegetation "matrix. To resolve this issue, the TBE-2018 procedure has been modified to add H202 to assist in breaking down the organic material that comprises this "matrix". This corrective action will be monitored closely by QA (NCR 18-25).
- 6.
The ERA October 2018 water Sr-90 sample was evaluated as Not Acceptable.
TBE's initial reported result of 36.8 pCi/L exceeded the upper acceptance range (22.9 - 36.4 pCi/L). After reviewing the data for this sample, it was discovered that there was a typographical error at the time the results were entered at the ERA website. The correct result in LIMS of 36.2 should have been submitted instead. This result is within ERA's acceptance limits. In addition to the typo error, ERA's very stringent upper acceptance limit of 116%
is not a reflection of TBE's ability to successfully perform this analysis. (NCR 18-23)
C. EIS Laboratory PE Results and Discussion All analyses met the specified acceptance criteria.
D. GEL Labs PE Results and Discussion
- 1.
The ERA February 2018 water Natural Uranium (and mass) results of 65.4 pCi/L and 97.6 µg/L were evaluated as Not Acceptable. No determination could be made as to a reason and all quality control criteria were met. The samples were re-analyzed and results fell in the acceptable range.
(Corrective Action Request and Report, CARR 180226-1150). All other analyses done for Peach Bottom met the specified acceptance criteria.

I.
Summary and Conclusions This report on the Radiological Groundwater Protection Program (RGPP) conducted for the Peach Bottom Atomic Power Station (PBAPS) by Exelon Nuclear covers the period 01 January 2018 through 31 December 2018. This evaluation involved numerous station personnel and contractor support personnel. At PBAPS, there are 31 permanent groundwater monitoring wells.
Installation of the wells began in 2006. Of these monitoring locations, none were assigned to the station's Radiological Environmental Monitoring Program (REMP). This report covers groundwater, surface water, seep water, and precipitation water samples collected from the environment on station property in 2018. During that time period, 437 analyses were performed on 238 samples from 39 locations. These 39 locations include 25 groundwater monitoring wells, 3 surface water sample points, 3 groundwater seeps, 2 yard drain sumps, and 6 precipitation water sampling points. Phase 1 of the monitoring was part of a comprehensive study initiated by Exelon to determine whether groundwater or surface water in the vicinity of PBAPS had been adversely impacted by any releases of radionuclides. Phase 1 was conducted by Conestoga Rovers and Associates (CRA) and the conclusions were made available to state and federal regulators as well as the public. Phase 2 of the RGPP was conducted by Exelon corporate and station personnel to initiate follow up of Phase 1 and begin long-term monitoring at groundwater and surface water locations selected during Phase 1. All analytical results from Phase 2 monitoring are reported herein.
Samples supporting the RGPP were analyzed for Tritium (H-3), Strontium-89 (Sr-89), Strontium-90 (Sr-90), gross alpha, gross beta, gamma-emitting radionuclides associated with licensed plant operations and isotopes known as
'hard to detects'.
In assessing all the data gathered for this report, it was concluded that the operation of PBAPS had no adverse radiological impact on the environment and there are currently no known active releases into the groundwater at PBAPS.
Tritium was not detected at any location in concentrations greater than the United States Environmental Protection Agency (USEPA) drinking water standard (and the Nuclear Regulatory Commission [NRG] Reporting Limit) of 20,000 pCi/L.
Tritium was not detected at concentrations greater than the minimum detectable concentration (MDC) in any surface water, seep water or precipitation water sample locations. Based on the sample data, tritium is not migrating off the station property at detectable concentrations.
II.
Introduction PBAPS is located along the Susquehanna River between Holtwood and Conowingo Dams in Peach Bottom Township, York County, Pennsylvania. The initial loading of fuel into Unit 1, a 40 MWe (net) high temperature gas-cooled reactor, began on 5 February 1966, and initial criticality was achieved on 3 March 1966. Shutdown of Peach Bottom Unit 1 for decommissioning was on 31 October 197 4. For the purposes of the monitoring program, the beginning of the operational period for Unit 1 was considered to be 5 February 1966. A summary of the Unit 1 preoperational monitoring program was presented in a previous report (1>. PBAPS Units 2 and 3 are boiling water reactors, each with a power output of approximately 1366 MWe. The first fuel was loaded into Peach Bottom Unit 2 on 9 August 1973. Criticality was achieved on 16 September 1973 and full power was reached on 16 June 1974. The first fuel was loaded into Peach Bottom Unit 3 on 5 July 197 4. Criticality was achieved on 7 August 197 4 and full power was first reached on 21 December 1974. Preoperational summary reports (2>(3> for Units 2 and 3 have been previously issued and summarize the results of all analyses performed on samples collected from 5 February 1966 through 8 August 1973.
This report covers those analyses performed by Teledyne Brown Engineering (TBE) on samples collected in 2018.
A Objective of the RGPP The objectives of the RGPP are as follows:
- 1. Ensure that the site characterization of geology and hydrology provides an understanding of predominant groundwater gradients based upon current site conditions.
- 2. Identify site risk based on plant design and work practices.
- 3. Establish an on-site groundwater monitoring program to ensure timely detection of inadvertent radiological releases to ground water.
- 4. Establish a remediation protocol to prevent migration of licensed material off-site and to minimize decommissioning impacts.
- 5. Ensure that records of leaks, spills, remediation efforts are retained and retrievable to meet the requirements of 10 CFR 50.75(g).
- 6. Conduct initial and periodic briefings of their site specific Groundwater Protection Initiative (GPI) program with the designated State/Local officials.
- 7. Make informal communication as soon as practicable to appropriate 2
State/Local officials, with follow-up notifications to the NRC, as appropriate, regarding significant on-site leaks/spills into groundwater and on-site or off-site water sample results exceeding the criteria in the REMP as described in the Offsite Dose Calculation Manual (ODCM).
- 8. Submit a written 30-day report to the NRC for any water sample result for on-site groundwater that is or may be used as a source of drinking water that exceeds any of the criteria in the licensee's existing REMP/ODCM for 30-day reporting of off-site water sample results.
- 9. Document all on-site groundwater sample results and a description of any significant on-site leaks/spills into groundwater for each calendar year in the Annual Radiological Environmental Operating Report (AREOR) for REMP or the Annual Radioactive Effluent Release Report (ARERR).
- 10. Perform a self-assessment of the GPI program.
- 11. Conduct a review of the GPI program, including at a minimum the licensee's self-assessments, under the auspices of the Nuclear Energy Institute (NEI).

Program Description
- 1.
Sample Collection Sample locations can be found in Table A-1 and Figures A-1 and A-2, Appendix A 3
Groundwater, Surface Water and Precipitation Water Samples of water are collected, managed, transported and analyzed in accordance with approved procedures. 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. 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 hydro geologist for adverse trends or changes to hydrogeologic conditions.
D.
Characteristics of Tritium Tritium is a radioactive isotope of hydrogen. The most common form of tritium is tritium oxide, which is also called "tritiated water." The chemical properties of tritium are essentially those of ordinary hydrogen.
Tritiated water behaves the same as ordinary water in both the environment and the body. 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 essentially all tritium is cleared.
Organically bound tritium (tritium that is incorporated in organic compounds) can remain in the body for a longer period.
Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced during nuclear weapons explosions, as a by-product in reactors producing electricity and in special production reactors, where the isotopes Lithium-? (Li-7) and/or Boron-10 (B-10) are activated to produce tritium. Like normal water, tritiated water is colorless and odorless. 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 has a 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 4
source of the health risk from exposure to tritium. Tritium emits a low energy beta particle 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.

Program Description A.
Sample Analysis This section describes the general analytical methodologies used by TBE and GEL Laboratories (GEL) to analyze the environmental samples for radioactivity for the PBAPS RGPP in 2018.
In order to achieve the stated objectives, the current program includes the following analyses:
- 1.
Concentrations of gamma emitters in groundwater and surface water.
- 2.
Concentrations of strontium in groundwater.
- 3.
Concentrations of tritium in groundwater, surface water and precipitation water.
- 4.
Concentrations of 'hard-to-detect' isotopes, Americium-241 (Am-241), Cerium-242/243/244 (Cm-242, Cm-243, Cm-244),
Plutonium-238/239/240 (Pu-238, Pu-239, Pu-240), Uranium-233/234/235/238 (U-233, U-234, U-235, U-238), lron-55 (Fe-55),
and Nickel-63 (Ni-63) in groundwater. These analyses are required based on tritium results.
B.
Data Interpretation The radiological data collected prior to PBAPS becoming operational were used as a baseline for operational data comparison. For the purpose of this report, PBAPS was considered operational at initial criticality. Several factors were important in the interpretation of the data:
- 1.
Lower Limit of Detection The lower limit of detection (LLD) is a minimum sensitivity value that must be achieved routinely by the analytical parameter.
5
- 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 factors such as calibration standards, sample volume or.
weight measurements, and sampling uncertainty. Exelon reports the uncertainty of a measurement created by statistical process (counting error) as well as all sources of error (Total Propagated Uncertainty or TPU). Each result has two values calculated.
Exelon reports the TPU by following the result with plus or minus +/-
the estimated sample standard deviation.
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 and surface water 12 nuclides, Manganese-54 (Mn-54), Colbalt-58/60 (Co-58, Co-60),
lron-59 (Fe-59), Zinc-65 (Zn-65), Niobium-95 (Nb-95),
Zirconium-95 (Zr-95), lodine-131 (1-131), Cesium-134/137 (Cs-134, Cs-137), Barium-140 (Ba-140) and Lanthanum-140 (La-140) are measured.
C.
Background Analysis A pre-operational REMP was conducted to establish background radioactivity levels prior to operation of the Station. The environmental media sampled and analyzed during the pre-operational REMP were atmospheric radiation, fall-out, domestic water, surface water, marine life and foodstuffs. The results of the monitoring were detailed in the report
- entitled PBAPS, Environs Radiation Monitoring Program, Preoperational Summary Report Units 2 and 3, September 1970- August 1973, January 1974 and PBAPS, Environs Radiation Monitoring Program, Preoperational Summary Report Units 2 and 3, June 1977. The pre-operational REMP contained analytical results from samples collected from the surface water, discharge, well and rain water.

Background Concentrations of Tritium The purpose of the following discussion is to summarize background measurements of tritium in various media performed by others. Additional detail may be found by consulting references (CRA 2006)(1).
- a.
Tritium Production Tritium is created in the environment from naturally occurring processes both cosmic and subterranean, as well as from anthropogenic (i.e., man-made) sources. In the upper atmosphere, "Cosmogenic" tritium is produced from the bombardment of stable nuclides and 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 Li present in crystalline rocks by neutrons produced by the radioactive decay of naturally abundant U and Th. Lithogenic production of tritium is usually negligible compared to other sources due to the limited abundance of Li in rock. The lithogenic tritium is introduced directly to groundwater.
A major anthropogenic source of tritium and Sr-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.
- b.
Precipitation Data Precipitation samples are routinely collected at stations around the world for the analysis of tritium and other radionuclides. Two publicly available databases that provide tritium concentrations in precipitation are Global Network of Isotopes in Precipitation (GNIP) and USEPA's RadNet database. GNIP provides tritium precipitation concentration data for samples collected worldwide from 1960 to 2006.
RadNet provides tritium precipitation concentration data for samples collected at stations throughout the U.S. from 1960 up to and including 2006. Based on GNIP data for sample stations located in the U.S. Midwest, tritium concentrations 7
peaked around 1963. This peak, which approached 10,000 pCi/L for some stations, coincided with the atmospheric testing of thermonuclear weapons. Tritium concentrations in surface water showed a sharp decline until 1975. A gradual decline has followed since that time. Tritium concentrations have typically been below 100 pCi/L since around 1980.
Tritium concentrations in wells may still be above the 200 pCi/L detection limit from the external causes described above. Water from previous years and decades is naturally captured in groundwater, so some well water sources today are affected by the surface water from the 1960s that was elevated in tritium.
- c.
Surface Water Data Surface water level measurements were collected at the surface water monitoring locations during the groundwater level measurement event. The purpose of the surface water monitoring was to provide surface water elevation data to evaluate the groundwater/surface water interaction at the Station.
The USEPA RadNet surface water data typically has a reported 'Combined Standard Uncertainty' of 35 to 50 pCi/L.
According to US EPA, this corresponds to a +/- 70 to 100 pCi/L 95% confidence bound on each given measurement.
Therefore, the typical background data provided may be subject to' measurement uncertainty of approximately +/- 70 to 100 pCi/L.
The radio-analytical laboratory is counting tritium results to an Exelon-specified 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 Groundwater Samples were collected from on-site wells throughout the year in accordance with the station radiological groundwater protection program.
Analytical results and anomalies are discussed below:

Tritium Samples from 33 locations were analyzed for tritium activity (Tables B-1.1 and B-11.1, Appendix B). Tritium values ranged from the detection limit to 14,300 pCi/L. Tritium was not detected in wells at or near the owner-controlled boundary. The location most representative of potential offsite user of drinking water is less than the MDC (Table B-1.1, Appendix B).
Low levels of tritium were detected at concentrations greater than the minimum detectable concentration (MDC) in 12 of 25 groundwater monitoring wells and the 2 yard drain locations. The tritium concentrations ranged from the detection limit to 14,300 pCi/L (Table B-1.1, Appendix B).
Tritium was detected in 2 surface water locations greater than the MDC.
Tritium concentrations in 2 of 29 samples ranged from 243 to 309 pCi/L.
(Table B-11.1, Appendix B)

9
The activity detected is consistent with historical levels. The activity detected is naturally occurring and the levels are considered to be background (Table 8-1.1, Appendix 8).
Hard-To-Detect Hard-To-Detect analyses were performed on a select group of groundwater water locations to establish baseline levels. The analyses for groundwater included Fe-55, Ni-63, Am-241, Cm-242, Cm-243/244, Pu-238, Pu-239/240, U-234, U-235 and U-238.
U-234 was detected in 7 of 18 groundwater monitoring locations analyzed. The concentrations ranged from 0.56 to 5.44 pCi/L.
U-235 was detected in 2 of 18 groundwater monitoring locations analyzed. The concentrations ranged from 0.15 to 0.26 pCi/L.
U-238 was detected in 7 of 18 groundwater monitoring locations analyzed. The concentrations ranged from 0.41 to 4.21 pCi/L. No plant-produced radionuclides were detected.
The activity detected is naturally occurring and the levels are considered to be background (Table 8-1.3, Appendix 8).
Gamma Emitters No power-production gamma emitters were detected in any of the samples (Table 8-1.2, Appendix 8).
- 8.
Surface Water Results Surface Water Samples were collected from six surface water locations throughout the year in accordance with the station radiological groundwater protection program. Analytical results are discussed below.
Tritium Samples from six locations were analyzed for tritium activity. Tritium was detected in 2 surface water locations greater than the MDC with concentrations in 2 of 29 samples ranged from 243 to 309 pCi/L.
(Table 8-11.1, Appendix 8) 10
Gamma Emitters No power-production gamma emitters were detected in any of the samples. No other gamma emitting nuclides were detected (Table B-11.2, Appendix B).
1 C.
Precipitation Water Results Samples were collected at six locations (1A, 1 B, 1S, 1SSE, 1Z, and 4M) in accordance with the station radiological groundwater protection program.
The following analysis was performed:
Tritium Samples from six locations were analyzed for tritium activity. Tritium activity was detected in 2 locations with concentrations for 3 of 61 samples ranging from 193 to 234 pCi/L. (Table B-111.1, Appendix B)
D.
Drinking Water Well Survey A drinking water well survey was conducted during the summer 2006 by CRA (CRA 2006)(1) around PBAPS. The water well inventory was updated in 2012(4l. The updated water well database search indicated a new water well off Station property within a one mile radius of the Station. The well is described as a "test" well and its use is listed as "unused". In summary, there were no significant changes in off Station groundwater use from 2006-2012.
E.
Summary of Results - Inter-Laboratory Comparison Program Inter-Laboratory Comparison Program results for TBE and Environmental Inc. (Midwest Labs) are presented in the AREOR.
F.
Leaks, Spills and Releases There were no inadvertent leaks, spills or releases of water containing licensed material to the environment in 2018.
G.
Trends A tritium plume has been identified northeast of the Unit 3 Turbine Building. The plume extends eastward toward well MW-PB-4. The plume is bounded on the north by wells MW-PB-12 and MW-PB-22. The plume is bounded on the south by wells MW-PB-20 and MW-PB-21.
11
The tritium plume is a result of licensed material entering the groundwater through degraded floor seams and penetration seals in the Unit 3 Turbine Building. The activity currently detected in the Unit 3 Turbine Building monitoring wells, MW-PB-24, 25, 26 and 27, is the result of legacy licensed material under the turbine building being transported eastward by natural hydrogeologic groundwater flow.
Tritium activity in the Unit 3 Turbine Building monitoring wells are trended.

Investigations MW-PB-4 In 2006, monitoring wells MW-PB-1 through MW-PB-14 were installed.
Tritium activity was detected in MW-PB-4, located north of the Unit 3 Circulating Water Pump Structure and MW-PB-12, north of the Administration Building. Groundwater flow on site is from west to east.
Monitoring wells were installed to the west, southwest and northwest of monitoring wells MW-PB-4 and MW-PB-12. The wells with the highest tritium activity are the wells installed directly east of and adjacent to the Unit 3 Turbine Building, wells MW-PB-24, 25, 26 and 27.
Investigation of potential sources identified that the likely source of groundwater contamination was due to degraded floor seams in the Unit 3 Turbine Building Moisture Separator area 116' elevation. Leaks internal to the building entered the groundwater through the degraded floor seams.
The floor seams were repaired in August 2010. The floor in the Unit 3 Turbine Building Moisture Separator area 116' elevation was sealed and recoated in October 2011.
MW-PB-29, 30 and 31 An extent-of-condition inspection of the Unit 2 Turbine Building Moisture Separator area 116' elevation floor was performed in October 2010. Minor degradation of the floor seams was identified and repaired.
In May 2011, monitoring wells MW-PB-29 and 30 were installed directly east of and adjacent to the Unit 2 Turbine Building; MW-PB-31 was installed southeast of and adjacent to the Unit 2 Turbine Building. These wells were installed to determine if a condition existed east of the Unit 2 Turbine Building that is similar to the condition east of the Unit 3 Turbine Building.
Tritium activity in these wells ranged from less than the MDC to 2,720 pCi/L. Samples from these wells were also analyzed for gamma-emitting isotopes and hard-to-detect radionuclides. All results are less than the MDC for each isotope.

Actions Taken
- 1. The Unit 3 cleaned and Condensate storage tank moat, sump and valve pit were recoated to eliminate a potential pathway for licensed enter the groundwater. These activities were completed order 04602739 and work request 01339203.
material to under work 13
- 2. During P3R21, the Unit 3 Recombiner Jet Compressor room floor drains were found plugged. One plug was removed and the second plug was modified to allow water to drain to the radwaste system in the event of a licensed material leak. This was completed under work request 01369404.
- 3. Installation of Monitoring Wells No groundwater monitoring wells were installed in 2018.
- 4. Actions to Recover/Reverse Plumes There were no actions to recover the plume.
J.
Deviations The data tables show that duplicate samples were obtained at several wells during 2018. These duplicate samples were obtained and analyzed for quality control purposes.
Due to regionaldrought conditions, seep SP-PB-3, located west of the Low Level RadWaste Storage Facility was dry during the 4th quarter of 2018. No sample was obtained or analyzed.
