I. Summary and Conclusions This report on the Radiological Environmental Monitoring Program (REMP) conducted for the Zion Nuclear Power Station (ZNPS) by ZionSolutions (ZS) covers the period 1 January 2018 through 31 December 2018. During that time period, 574 analyses were performed on 525 samples. In assessing all the data gathered for this report and comparing these results with preoperational data, it was concluded that the operation of ZNPS had no adverse radiological impact on the environment.
Public water samples were analyzed for concentrations of gross beta, tritium and gamma-emitting nuclides. No fission or activation products were detected.
Gross beta activities detected were consistent with those detected in previous years, and with levels of natural radioactivity typically observed in the environment.
Food product samples/vegetation were analyzed for concentrations of gamma-emitting nuclides. No fission or activation products were detected.
Fish (commercially and recreationally important species) and sediment samples were analyzed for concentrations of gamma-emitting nuclides. No Cesium-137 (Cs-137) activity was detected in fish or sediment samples. No plant-produced fission or activation products were found in fish or sediment.
Air particulate samples were analyzed for concentrations of gross beta and gamma-emitting nuclides. No fission or activation products were detected.
Environmental gamma radiation measurements were performed quarterly using thermoluminescent dosimeters.
The RETDAS Computer Model predicts concentrations of activation and fission products in off-site media (fish, vegetation, sediment, air and water) based on measured concentrations of sampled dust and permitted water discharges leaving the site. The results of these computer model predictions in 2018 indicated the projected concentrations in fish, sediment, vegetation, air and water were well below levels that can be measured with state of the art laboratory analysis.
This is why the concentrations off site and the resulting dose impact are calculated by computer. The levels are predicted to be too low to measure off site, as demonstrated by the results of environmental sampling summarized in this report.
Lastly, in Appendix E is the annual groundwater report summarizing the results of groundwater samples collected on site quarterly. In 2018, tritium was
,identified in groundwater for the first time since the station's 10CFR50 licenses were transferred from Exelon to Zion Solutions on September 1, 2010. Levels just above MDA were identified in well 08S for approximately six months, and then dropped below MDA, and have remained below MDA since then. This is reviewed and discussed in Appendix E.

II. Introduction The Zion Nuclear Power Station (ZNPS), consisted of two 1,100 MWt pressurized water reactors, was owned and operated by Exelon Corporation, and is located in Zion, Illinois adjacent to Lake Michigan. Unit No. 1 went critical in December 1973. Unit No. 2 went critical in September 1974. The plant permanently ceased operation in January of 1998 and has been permanently defueled. The plant is in the final stages of decommissioning and' the remaining sources of radioactive material on site include spent fuel stored in canisters on the Independent Spent Fuel Storage Installation (ISFSI),
demolished building materials awaiting shipment to the low level waste and disposal facility in Utah, and trace amounts of radioactive material in backfilled structures and surface soil per the Station's License Termination Plan (LTP).
The site is located in northeast Illinois on the western shore of Lake Michigan, approximately 50 miles north of Chicago, Illinois.
This report covers those analyses performed by Teledyne Brown Engineering (TBE) and Mirian Technologies on samples collected during the period 1 January 2018 through 31 December 2018.
A. Objectives of the REMP The objectives of the REMP are to:
- 1. Provide data on measurable levels of radiation and radioactive materials in the site environs
- 2. Evaluate the relationship between quantities of radioactive material released from the plant and resultant radiation doses to individuals from principal pathways of exposure
- 3. Validate the effluent computer model that predicts radioactive material concentrations at populated off-site sample locations.
B. Implementation of the Objectives The implementation of the objectives is accomplished by:
- 1. Identifying significant exposure pathways
- 2. Establishing baseline radiological data of media within those pathways
- 3. Continuously monitoring those media before, during and after Station operation to assess Station radiological impacts (if any) on man and the environment

Ill. Program Description A. Sample Collection Samples for the ZNPS REMP were collected for Zion Solutions (ZS) by Environmental Inc. (Midwest Labs). This section describes the general collection methods used by Environmental Inc. (Midwest Labs) to obtain environmental samples for the ZNPS REMP in 2018. Sample locations and descriptions can be found in Table B-1 and Figures B-1 and B-2, Appendix B. The sampling methods used by Environmental Inc.
(Midwest Labs) are listed in Table B-2.
Aquatic Environment The aquatic environment was evaluated by performing radiological analyses on samples of public water, fish and sediment. Two gallon water samples were collected monthly from four public water locations (Z-14, Z-15, Z-16 and Z-18). Control locations were Z-14 and Z-18. All samples were collected in new unused plastic bottles, which were rinsed at least twice with source water prior to collection. Fish samples comprised of the edible flesh portion of white sucker, largemouth bass, common carp, brown trout, lake trout and burbot were collected semiannually at two locations, Z-26 and Z-27. Sediment samples composed of recently deposited substrate were collected at one location semiannually, Z-25.
Atmospheric Environment The atmospheric environment was evaluated by performing radiological analyses on samples of air particulates. Airborne particulate samples were collected and analyzed weekly at four locations (Z-01, Z-02, Z-03, and Z-13). The control location was Z-13. Airborne particulate samples were obtained at each location, using a vacuum pump with 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 food product samples. Food products were collected annually in August at three locations (Z-Control, Z-Quad 3 and Z-Quad 4). The control location was Z-Control. Various types of samples were collected and placed in new unused plastic bags and sent to the laboratory for analysis.

Ambient Gamma Radiation Direct radiation measurements were made with Panasonic Environmental TLD type 814 with 3 CaS04 elements. Each location consisted of 2 TLD sets. The TLD locations were placed on, around and surrounding the ZNPS site at the following locations:
Inner Ring: Z-01, Z-02, Z-03, Z-101, Z-102, Z-103, Z-104, Z-105, Z-106, Z-107, Z-108, Z-109, Z-121, Z-124, Z-125, Z-129, Z-130, Z-131 Special Interest: Z-112, Z-113, Z-114, Z-115 Outer Ring: Z-209, Z-211, Z-212, Z-213, Z-214, Z-215, Z-216 Control: Z-13 The specific TLD locations were determined by the following criteria:
- 1. The presence of relatively dense population;
- 2. Site meteorological data taking into account distance and elevation for each of the sixteen-22 1/2 degree sectors around the site, where estimated annual dose from ZNPS, if any, would be most significant; 3: On hills free from local obstructions and within clear line of sight to construction activities (where practical) and the ISFSI;
- 4. And near the closest dwelling to the demolition activities in the prevailing downwind direction and the ISFSI.
(Two TLDs - each comprised of three CaS04 elements enclosed in plastic - were placed at each location approximately four to eight feet above ground level. The TLDs were exchanged quarterly and sent to Mirion Technologies for analysis.
B. Sample Analysis This section describes the general analytical methodologies used by TBE to analyze the environmental samples for radioactivity for the ZNPS REMP in 2018. The analytical procedures used by the laboratories are listed in Table B-2.
In order to achieve the stated objectives, the current program includes the following analyses:
4 2018 Zion AREOR
- 1. Concentrations of beta emitters in public water and air particulates using gross beta analysis with proportional detectors.
- 2. Concentrations of gamma emitters in public water,- air particulates, vegetation, fish, and sediment using high purity germanium (HPGe) gamma spectroscopy.
(.
- 3. Concentrations of tritium in public water using liquid scintillation
, analysis (LSC) with the energy window focused on the tritium
. emission energy.
- 4. _Ambient gamma radiation levels at various locations on and off
- site up to 1O miles away using multi-chip thermoluminescent dosimeters {TLDs).
C. Data Interpretation The radiological and direct radiation data collected prior to Zion Nuclear Power Station becoming operational were used as a baseline with which these operational data were compared. For the purpose of this report, Zion Nuclear Power Station was considered operational at initial criticality. In addition, data was compared to previous years' operational data for consistency and trending. Several factors were important in the interpretation of the data:
- 1. Lower Limit of Detection and Minimum Detectable Concentration
- The l9wer 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 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 ZNP.S 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 5
2018 Zion AREOR
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 public water, fish, vegetation, sediment and air particulates 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.
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 2018 the ZNPS REMP had a sample recovery rate in excess of 98%. Sample anomalies and missed samples are listed in the tables below:

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 There were no program changes for 2018.
IV. Results and Discussion A. Aquatic Environment
- 1. Public Water Samples were taken weekly and composited monthly at four locations (Z-14, Z-15, Z-16 and Z-18). The following analyses were performed.
Gross Beta Samples from all locations were analyzed for concentrations of gross beta. Gross beta was detected in 30 of 48 samples. The values ranged from 1.8 pCi/1 to 4.9 pCi/1. Concentrations detected were consistent with those detected in previous years.
(Table C-1.1, Appendix C) (Figures C-1 and C-2, Appendix C) 7 2018 Zion AREOR
Tritium Quarterly composites of weekly collections were analyzed for tritium activity (Table C-1.2, Appendix C). No tritium was detected and the LLD was met (Figures C-3 and C-4, Appendix C).
Gamma Spectrometry Samples from both locations were analyzed for gamma-emitting nuclides. No nuclides were detected and all required LLDs were met. (Table C-1.3, Appendix C)
- 2. Fish Fish samples comprised of white sucker, largemouth bass, common carp, brown trout, lake trout and burbot were collected at two locations (Z-26 and Z-27) semiannually. The following analysis was performed:
Gamma Spectrometry The edible portion of fish samples from both locations was analyzed for gamma-emitting nuclides No nuclides were detected and all required LLDs were met. (Table C-11.1, Appendix C)
- 3. Sediment Aquatic sediment samples are normally collected at one location (Z-25) semiannually. The fall sample was collected at Z-26 due to unsafe conditions at location Z-25 in October, 2018. The following analysis was performed:
Gamma Spectrometry Sediment samples from Z-25 and Z-26 were analyzed for gamma-emitting nuclides. No nuclides were detected and all required LLDs were met. (Table C-111.1, Appendix C)
- 8. Atmospheric Environment
- 1. Airborne - Air Particulates Continuous air particulate samples were collected from four locations on a weekly basis. Three locations were within the ZNPS site boundary (Z-01, Z-02 and Z-03) and the fourth is located 10 miles north and is the control location (Z-13). The 8
2018 Zion AREOR
following analyses were performed:
Gross Beta Weekly samples were analyzed for concentrations of beta emitters. Detectable gross beta activity was observed at all locations, except one control air sample (see Table C-IV.1 ).
Comparison of results among the three groups aids in determining the effects, if any, resulting from the operation of ZNPS. The positive results from the three On-Site locations ranged from 4E-3 pCi/m 3 to 41 E-3 pCi/m 3 with a mean of 15E-3 pCi/m3.
The results from the Control location ranged from 7E-3 pCi/m 3 to 39E-3 pCi/m 3 with a mean of 16E-3 pCi/m 3 and one result <LLD.
Comparison of the 2018 air particulate data with previous year's data indicates there is no off site impact resulting from demolition activities at ZNPS. Concentrations detected were consistent with those detected in previous years. (Table C-IV.1 and C-IV.2, Appendix C)
Gamma Spectrometry Weekly samples were composited quarterly and analyzed for gamma-:emitting nuclides. No plant-related nuclides were detected and all required LLDs were met. Naturally occurring Be-7 was detected; the source of this is described later in this report.
(Table C-IV.3, Appendix C)
C. Terrestrial Environment
- 1. Food Product Food product samples were collected at three locations (Z-Control, Z-Quad 3 and Z-Quad 4) when available. The following analysis was performed:
Gamma Spectrometry Samples from all locations were analyzed for gamma-emitting nuclides. No nuclides were detected and all required LLDs were met. (Table C-V.1, Appendix C)
D. Ambient Gamma Radiation Ambient gamma radiation levels were measured utilizing Panasonic Environmental Type 814 CaSQ4 thermoluminescent 9
2018 Zion AREOR
dosimeters (TLD's). Sixty-four TLDs were mounted at 30 locations around the site. Results of TLD measurements are listed in Tables C-Vl.1 to C-Vl.3, Appendix C .
. Most TLD measurements were below 25 mR/quarter, with a range of 13 mR/quarter to 32 mR/quarter. As there are duplicate TLDs posted at each location, the highest value is always reported in Appendix C for each location. The 13 mR/quarter reading was from the first quarter at location Z-101-1, but the higher value of 14 mR/quarterwas reported (Z-101-2) in Appendix C.
When direct dose in 2018 is compared to direct dose the previous five years (2013-2018) at the four compass points surrounding decommissioning activities (Figure C-8) within the site boundary, there is a visible drop in direct dose. This is attributed to a steady reduction in source term over the same period, including demolition of structures inside the former protected area, and shipment by rail and truck of the debris to Energy Solutions low level waste facilities in Utah.
When looking at a more specific set of TLD's, those most likely to be impacted by direct radiation from the Independent Spent Fuel.
Storage Installation (ISFSI) by close proximity and line of site positioning inside the site boundary (Figure C-7), a significant increase in direct dose is evident in 2015 following completion of the transfer of spent fuel to the ISFSI. After 2015, a drop in direct dose is evident due in part to site source term reduction, and to a lesser extent, decay of the spent fuel.
E. Land Use Survey A Land Use Census conducted during October 2018 around the Zion Nuclear Power Station (ZNPS) was performed by Zion Station Personnel for ZS to comply with Chapter 3 of the Zion Offsite Dose Calculation Manual. The purpose of the survey was .
to document the nearest resident, milk producing animal and garden of greater than 500 ft2 in each of the sixteen 22 % degree sectors around the site. The results of this survey are summarized below:

- Gardens are located using Google Maps to narrow down areas that appeared to have been ploughed by aerial photographs, then visually verified by visiting these new locations.
Milk-producing animal located by internet search for dairies advertising the sale of milk for public consumption.
F. Errata Data Minor.errors were identified in the 2016 and 2017 AREORs.
Corrections were made and the corrected pages with change bars are included in Appendix F.
In the 2016 AREOR, there were inconsistencies identified between Tables C-Vl.1 through C-Vl.3 in the data used to summarize TLD results and standard. deviations reported by quarter and category. This was due to manual transcription and rounding errors. To alleviate these error sources, a verified and validated MS Excel workbook was created that permitted copying and pasting the raw TLD data supplied in a spreadsheet directly from Mirion into a worksheet. The workbook then calculated all averages, standard deviations, minimums and maximums reported from 254 analyses and populated all results in required 11 2018 Zion AREOR
tabulated format for Appendix C with no transcription or rounding errors.
As Teledyne creates the same tabulated data, it provides independent verification of the results.
In the 2017 AREOR, Figures C-7 and C-8 reported mrem per year between 2013 and 2017but it was actually average quarterly dose per year and the y-axis labels were corrected.
G. Summary of Results - Inter-Laboratory Comparison Program The TBE Laboratory analyzed Performance Evaluation (PE) samples of air particulate, air iodine, milk, soil, vegetation, and water matrices for various analytes. The PE samples supplied by Analytics Inc.,
Environmental Resource Associates (ERA) and Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following pre-set acceptance criteria:
A. 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 evaluates the reported ratios based on internal QC requirements based on the DOE MAPEP criteria.
B. ERA Evaluation Criteria ERA's evaluation report provides an acceptance range for control and warning limits with associated flag values. ERA's 1 acceptance limits are established per the USEPA, National Environmental Laboratory Accreditation Conference (NELAC),
state-specific Performance Testing (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.
C. DOE Evaluation Criteria MAPEP's evaluation report provides an acceptance range with associated flag values. MAPEP defines three levels of performance:
- Acceptable (flag = "A") - result within +/- 20% of the reference value
- Acceptable with Warning (flag = "W") - result falls in the +/- 20%
to +/- 30% of the reference value
- Not Acceptable (flag = "N") - bias is greater than 30% of the reference value 12 2018 Zion AREOR
/
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.
For the TSE laboratory, 166 out of 172 analyses performed met the specified acceptance criteria. Five analyses did not meet the specified acceptance criteria for the following reasons and were addressed through the TSE Corrective Action Program.
- 1. TSE 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 TSE 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.
TSE 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 4th Qtr result passed at 105% (NCR 18-20)
- 3. The Analytics September milk 1-131 result was evaluated as Not Acceptable (Ratio of TSE 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. NOTE: TBE's 4h Qtr result passed at 101% (NCR 18-24) .
- 4. The Analytics September soil Cr-51 result was evaluated as Not Acceptable (Ratio of TSE 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 TSE-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).
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)
The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.

'Two TLDs are posted at each location for redudency. The averages are based on the highest reading at each station. The ranges are based on all results.
The total number of analyses is based on all TLD results - there are 3 chips read in each TLD, so literally, there are 762 analytses performed on 254 TLD's - the 2018 TLD results reflect 2 TLDs that were damaged/lost.

- Note: There are 2 TLDs posted at each indicator station for redundancy and data recovery.
In reporting results, the higher of the two readings are reported, except when reporting minimums, which are based on all results. There are six (6) TLDs posted at the control location, and that value is based on an average of all six results each quarter.
The period minimum in Table C-Vl.3, above, was 13 mR/quarter at location Z-101. It was the single lowest result of all 254 TLD's analyzed during the year.
