1.0 INTRODUCTION
This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2023 for the Union Electric Company (dba Ameren Missouri) Callaway Energy Center.
The objectives of the REMP are to monitor potential critical pathways of radioactive effluent to man and determine the radiological impact on the environment caused by operation of the Callaway Energy Center. The Radiological Environmental Monitoring Program was initiated in April 1982.
The Callaway Energy Center consists of one 3565 MWt pressurized water reactor, which achieved initial criticality on October 2, 1 984. The plant is located on a plateau approximately ten miles southeast of the City of Fulton in Callaway County, Missouri and approximately eighty miles west of the St. Louis metropolitan area. The Missouri River flows by the site in an easterly direction approximately five miles south of the site at its closest point.
Tabulation of the individual analyses for the year 2023 is included in Part II of this report.

SUMMARY
The Radiological Environmental Monitoring Program, as required by the U.S. Nuclear Regulatory Commission (NRC) Technical Specifications for the Callaway Energy Center is described herein.
Results for the year 2023 are summarized and discussed.
For the year, the Callaway Energy Center was operated in compliance with Offsite Dose Calculation Manual (ODCM) and Radiological Effluent Controls (REC) requirements. Results from the REMP indicate the Callaway Energy Center has had no significant radiological impact on the health and safety of the public or on the environment.

3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 31 Program Design and Data Interpretation The purpose of the Radiological Environmental Monitoring Program at the Callaway Energy Center is to assess the impact of the plant on its environment.
For this purpose, samples are collected from waterborne, airborne, ingestion and terrestrial pathways and analyzed for radioactive content.
Direct radiation levels are monitored by thermoluminescent dosimeters (TLD5).
Sources of environmental radiation can include the following:
(1 )
Natural background radiation arising from cosmic rays and primordial radionuclides; (2)
Fallout from atmospheric nuclear detonations; (3)
Releases from nuclear power plants, planned or accidental; and (4)
Industrial and medical radioactive waste.
Effects due to operation of the Callaway Energy Center must be distinguished from those due to other sources in interpreting the data.
The indicator-control concept is a major interpretive aid; where feasible the design of the Callaway Energy Center program has both indicator and control stations. Most types of samples are collected at indicator locations (nearby, downwind, or downstream) and at control locations (distant, upwind, or upstream). A station effect would be indicated if the radiation level at an indicator location was significantly larger than that at the control location. The difference would have to be greater than could be accounted for by typical fluctuations in radiation levels arising from other sources.
The monitoring program includes analyses for iodine-i 31
, a fission product, and tritium, which is produced by cosmic rays, atmospheric nuclear detonations, and also by nuclear power plants.
Most samples are analyzed for gamma-emitting isotopes, with results for the following groups quantified: zirconium-95, cesium-i 37, and cerium-i 44. These three gamma-emitting isotopes are selected as radiological impact indicators because of the different characteristic proportions in which they appear in the fission product mix produced by a nuclear reactor and that produced by a nuclear detonation.
Each of the three isotopes is produced in roughly equivalent amounts by a reactor: each constitutes about i 0% of the total activity of fission products ten days after reactor shutdown. On the other hand, ten days after a nuclear explosion, the contributions of zirconium-95, cerium-i44, and cesium-i37 to the activity of the resulting debris are in the approximate ratio 4:i :0.03 (Eisenbud,i963).
The other group quantified consists of niobium-95, ruthenium-i03 and -i06, cesium-i34, barium-lanthanum-i 40, and cerium-i 4i
. These isotopes are released in small quantities by nuclear power plants, but to date their major source of injection into the general environment has been atmospheric nuclear testing.
Nuclides of the next group, manganese-54, cobalt-58 and-60, and zinc-65, are activation products and arise from activation of corrosion products. They are typical components of nuclear power plant effluents but are not produced in significant quantities by nuclear detonation.
Nuclides of the final group, beryllium-7, which is of cosmogenic origin, and potassium-40, a naturally-occurring isotope, were chosen as analytical monitors and should not be considered radiological impact indicators.
Other means of distinguishing sources of environmental radiation can be employed in interpreting the data. Current radiation levels can be compared with previous levels, including pre-operational data.
Results of the monitoring program can be related to those obtained in other parts of the world.
Finally, results can be related to events known to cause elevated levels of radiation in the environment, e.g., a nuclear accident.

3.2 Program Description The sampling and analysis schedules for the environmental radiological monitoring program at the Callaway Energy Center are summarized in Tables 5.1 and 5.2 and briefly reviewed below. Table 5.1 identifies sampling locations and specifies as to type (indicator or control) and its distance, and direction relative to the reactor site.
The types of samples collected at each location, required analyses and the frequency of collections are presented in Table 5.2.
To monitor the air environment, airborne particulate and airborne iodine samples are collected by continuous pumping, at six locations. The airborne particulates are collected on glass fiber filters and the airborne iodine through activated charcoal cartridges. Both filters and cartridges are exchanged weekly. Airborne particulates are analyzed for gamma-emitting isotopes. Charcoal cartridges are analyzed for iodine-131.
The ingestion pathway is monitored by sampling of milk (if available), fish and green leafy vegetation.
Milk samples are collected semimonthly when animals are on pasture and monthly the rest of the year. There were no milk indicator or control stations identified by the Land Use Census for the subject year.
Milk samples are analyzed for iodine-131 and gamma-emitting isotopes when available.
Monthly during the growing season, edible green leafy vegetation is collected from both indicator and control locations. Vegetation samples typically consist of mustard greens, turnip greens, cabbage, lettuce, collards, radish greens, swiss chard, broccoli and poke. Other edible broad leaf vegetation is collected if primary varieties are not available. The samples are analyzed for iodine-1 31 and other gamma-emitting isotopes.
The waterborne pathway is monitored by sampling surface water, groundwater and drinking water, and shoreline sediments. Water samples are analyzed for tritium and gamma-emitting isotopes, and sediments are analyzed for gamma-emitting isotopes.
The waterborne pathway is also monitored by upstream and downstream semiannual collections of fish. The five most abundant recreational or commercial fish species are collected. The edible portions of the samples are analyzed for gamma-emitting isotopes.
Monthly composite samples of surface water from the Missouri River are collected from one indicator location (S02) and from one control location (SOl ). The surface water samples are composites of daily collections by automatic river samplers.
Onsite surface water from ponds is analyzed for tritium and gamma-emitting isotopes. The collection frequencies are semiannually.
To monitor possible sources of ground water contamination due to plant operations, non-potable ground water samples were collected monthly or quarterly from well locations both onsite and along the discharge pipeline. The samples were analyzed for tritium and gamma-emitting isotopes.
Potable well water samples are collected quarterly from the plant drinking water supply and neighboring property owners.
The samples were analyzed for tritium and gamma-emiffing isotopes.
Shoreline sediment is collected semiannually at the plants intake (A) and discharge (C). These samples are collected within two feet of the edge of the water. The samples are analyzed for gamma-emitting isotopes.

3.2 Program Description (continued)
The direct ambient gamma radiation pathway is also considered. This exposure is monitored by thermoluminescent dosimeters (TLDs) at forty-four locations in and around the Callaway site. The TLDs are placed in 16 sectors around the plant as specified in the ODCM-RECS. Five of the TLD stations have neutron monitoring capability and three locations are designated as controls. TLDs are exchanged and analyzed quarterly.
Soil is collected annually from seven indicator locations (F2, F6, PR3, PRZ, W2, W5 and W6) and two control locations (M9, WY) to monitor the terrestrial environment. The samples are analyzed for gamma-emitting isotopes.
3.3 Program Execution The program was executed as described in the preceding section with the following exceptions.
(1) Food Products-Leafy Green Vegetables:
There were no viable samples available for collection in April 2023 at any of the sampling locations, CA-FPL-V9, CA-FPL-V1 6, CA-FPL-V1 9 and CA-FPL-V20 due to it being too early in the growing season (CR#202302405).
Sample location CA-FPL-V9 was unable to provide a vegetation sample in May 2023 due growing conditions (CR#202303264).
(2) Non-potable Wells:
The well sample scheduled to be collected 2/24/23 at location CA-WWA-UY MW-47 could not be collected due to a dry well (CR#202301 282).
The well sample scheduled to be collected 5/31/23 at well location CA-WWA-U1 MW-47 could not be collected due to a dry well (CR#202303703).
The well samples scheduled to be collected 1 1/73/23 at well locations CA-WWA-U1 MW-004, CA-WWA-U1 -MW-005, CA-VVWA-U1 MW-47 could not be collected due to dry well conditions (CR#202308663).
(3) Direct Radiation:
During the quarterly changeout of TLDs from first to second quarter the TLD at location CA-IDM-1 0 was found to be missing (CR#202302537).
(4) Surface Water:
River Samplers Out of Service Time:
Sampler SOY, the upstream sampler located in the plant water intake structure about 550 feet upstream of the discharge, was out of service for approximately 0 days (0.0% of the year) during 2023.
Sampler 502, the downstream sampler located at the end of the mixing zone in Portland, MO, was out of service for approximately 1 3 days (3.56% of the year) during 2023.
Functioning 96.44% of 2023. Portland pump noise issue 6 days without automatic sampling (CR 202208509). Portland River sampler vault flooded 7 additional days without automatic sampling (CR 202305288).
During those out of service times, daily grab samples are collected as required per Callaways procedures.

3.7 Land Use Census The Land Use Census is performed annually during the growing season.
In 2023 the field inspection of the sectors was conducted September 27, 2023, within a five-mile radius of the Callaway Energy Center. The area around the plant was divided into 1 6 meteorological sectors.
The locations of the nearest resident, nearest milk animal, and nearest garden of greater than 500 square feet producing broadleaf vegetation were identified.
The results of the census are presented in Table 5.4.
The table includes radial direction and distance from the Callaway Energy Center for each location. The bearings listed in Table 5.4 were measured from the Callaway Plant to the sample location.
There are no changes to the closest residents in 2023.
A potential new garden was identified in sector R. No milking animals were located during the survey however one resident stated that they are in the process of acquiring cows and anticipate having goats milking sometime in 2024. We intend to update ODCM and Land Use as required once we are notified of the actual start of milking and usage.
All residents included in the summary were verified by the Callaway County Assessors GIS aerial photography.
The Missouri Department of Natural Resources has not identified any new water wells along the Mud Creek or Logan Creek corridors.
The US Army Corps of Engineers was contacted and they confirmed that no new drinking water intakes have been located along the Missouri River within ten (1 0) river miles downstream from the Callaway Plant.
In addition, no irrigation uses of the Missouri River were identified between the discharge point and Portland, MO during the survey.
3.8 Errata from previous Annual Radioloalcal Environmental Operating Reports None.

4.0 RESULTS AND DISCUSSION All collections and analyses were made as scheduled, except for those listed in Table 5.5.
Results are summarized in Table 5.6 as recommended by the Nuclear Regulatory Commission.
For each type of analysis and sample medium, the table lists the mean and range of all indicator and control locations, as well as that location with the highest mean and range.
The tabulated results of all measurements are not included in this section, although references to these results will be made in the discussion. A complete tabulation of results for 2023 is contained in Part II of the Annual Report on the Radiological Environmental Monitoring Program for the Callaway Energy Center.
4.1 Atmospheric Nuclear Detonations and Nuclear Accidents The Fukushima Dalichi nuclear accident occurred March 1 1, 201 1
. There were no reported accidents involving significant release to the environment at nuclear reactor facilities in 2023. The last reported atmospheric test was conducted on October 1 6, 1 980, by the Peoples Republic of China. There were no reported atmospheric nuclear tests in 2023.
4.2 Program Findings Airborne Particulates and Iodine No gamma-emitting isotopes were identified other than naturally occurring Be-f. There was no I-i 31 activity detected in any of the charcoal canister samples.
Air sampling for 2023 indicates no radiological effects of plant operation.
Direct Radiation (TLD5)
Forty-four gamma sensitive TLDs were placed in 1 6 sectors around the Callaway site each quarter.
Measurements from forty-one indicator locations averaged 1 5.0 mrem/quarter and the three control locations averaged 14.1 mrem/quarter. Readings ranged from 9.8 to 17.5 mrem /quarter, with the highest quarterly average from the indicator location CA-IDM-10, averaging 16.7 mrem/quarter.
The TLD readings were consistent with the results for the years 2000 through 2022 as detailed in table 5.7.
Five neutron sensitive TLDs were placed in locations at the Site Boundary closest to the Independent Spent Fuel Storage Facility Installation (ISFSI) and at a control location approximately 14 miles from the site. There was no significant measurable neutron dose and there was no effect from the ISFSI in 2023.
Milk Sampling has been discontinued since 201 8 because there are not enough sampling locations to fulfill the milk sampling requirement.
No milking animals were located during the 2023 Land Use Census. Leafy green (broadleaf) vegetation sampling was performed in lieu of milk sampling.

4.2 Program Findings (continued)
Broadleaf Vegetation There was no I-i 31 activity detected in broadleaf vegetation samples. No gamma-emitting isotopes were detected in broadleaf vegetation samples except for naturally occurring potassium-40.
Vegetation data for 2023 show no radiological effects of plant operation.
Fish Edible portions of fish were analyzed by gamma spectroscopy. No gamma-emitting isotopes, except for naturally occurring potassium-40, were detected in fish.
Soil Cesium-i 37 activity was detected at six of the seven indicator sample locations at an average concentration of 1 71 pCi/kg dry. The cesium-i 37 activity is consistent with levels observed from 1 999 through 2022; these levels are attributable to the deposition of fallout from previous decades.
Surtace Water Tritium was detected in nine out of the thirteen samples tested in 2023 at the downstream location 502 ranging from 205 pCi/L to 1 1 63 pCl/L.
No gamma-emitting isotopes were detected in any of the samples taken in 2023.
Surface Water, Ponds No tritium or gamma activity was detected in any of the twelve pond samples analyzed in 2023.
Drinking Water Wells (potable water)
Sixty-four samples from sixteen different locations were analyzed for tritium and gamma-emitting isotopes in 2023. No tritium or gamma-emitting isotopes were detected.
Wells and Ponds (non-potable water)
Eight groundwater samples from deep wells F-05 and F-15 were analyzed for tritium and gamma-emitting isotopes. No tritium or gamma emitting isotopes detected form any of the deep well samples taken in 2023.
Twenty-six samples from the wells that were part of the limited site investigation (LSI) in 201 4 were analyzed for tritium in 2023 including Wells CA-WWA-Ui MW-031
, CA-WWA-Ui MW-034, CA-WWA-Ui MW-036, CA-WWA-Ui MW-039, CA-WWA-Ui MW-047, CA-WWA-Ui MW-058 and CA-WWA-Ui MW-059.
Fourteen were positive ranging from 1 95 to 370 pCi/L with an average concentration of 253 pCi/L. These levels were a slight decline from 2022 and show that the natural attenuation described in previous AREORs is continuing.
- Wells, CA-WWA-Ui MW-GWS, CA-WWA-Ui MW-937B, CA-WWA-Ui MW-937D, CA-WWA Ui MW-939R, CA-WWA-Ui MW-940, CA-WWA-Ui MW-941 and CA-WWA-Ui MW-IFSFI (sump) are in the Plant Protected Area adjacent to the power block. As described in previous AREORs, the tritium activity in the wells within the power block are believed to be the result of washout from gaseous effluents. The 2023 results are consistent with the results from 201 5 through 2022 and demonstrate the continued decline from previous years due to natural attenuation.
9
4.2 Program Findings (continued)
Sediments Two samples of shoreline sediments were collected in May and again in September of 2023 at both an indicator and a control location and analyzed for gamma-emitting isotopes. Cesium-i 37 was detected at both the indicator and control location for the September collection at a level of 52.0 and 53.4 pCi/kg dry respectively; these levels are attributable to the deposition of fallout from previous decades. No other gamma-emitting isotopes were detected excepting naturally occurring potassium-40 in any of the sediment samples.

ADiendix A Interlaboratorv/ Intralaboratory Comparison Program Results Microbac Laboratories
- Northbrook (previously Environmental Inc.) has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality program in December 1971.
These programs are operated by agencies and/or companies which supply environmental sample types containing concentrations of radionuclides known to the issuing entity but not to participant laboratories.
The purpose of such a program is to provide an independent check on a laboratorys analytical procedures and to alert it of any possible problems.
Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits.
Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.
Results in Table A-I were obtained through participation in the RAD PT Study Proficiency Testing Program administered by Environmental Resource Associates, serving as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada.
Table A-2 lists results for thermoluminescent dosimeters (TLD5), via irradiation and evaluation by the University of Wisconsin-Madison Radiation Calibration Laboratory at the University of Wisconsin Medical Radiation Research Center.
Table A-3 lists results of the analyses on intralaboratory spiked samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.
Table A-4 lists results of the analyses on intralaboratory blank samples for the past twelve months. Data for previous years available upon request.
Table A-5 lists analytical results from the intralaboratory duplicate program for the past twelve months. Acceptance is based on each result being within 25% of the mean of the two results or the two sigma uncertainties of each result overlap.
The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.
Results in Table A-f were obtained through participation in the MRAD PT Study Proficiency Testing Program administered by Environmental Resource Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).
Attachment A lists the laboratory acceptance criteria for various analyses.
Out-of-limit results are explained directly below the result.

APPENDIX B.
DATA REPORTING CONVENTIONS Data Reporting Conventions I.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end olthe collection period.
2.0.
Single Measurements Each single measurement is reported as follows:
x +/- s where:
x = value ofthe measurement; 5 = 2a counting uncertainty (corresponding to the 95% confidence level).
In cases where the activity is less than the lower limit of detection L, it is reported as:
< L, where L = the lower limit of detection based on 4.66a uncertainty for a background sample.
3.0. Duplicate analyses If duplicate analyses are reported, the convention is as follows.
- 3. 1 Individual results:
For two analysis results; x1 +/- s and x2 +/- 2 Reported result:
x +/- s; where x = (1/2) (x1 + x2) and s = (1/2) -Js +
3.2.
Individual results:
< L1
< L2 Rerorted result: < L, where L = lower of L1 and L2 3.3.
Individual results:
x +/- s, < L Reported result:
x +/- s if x L; < L otherwise.
4.0. Computation ofAverages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average x and standard deviation s of a set of n numbers x1, x2
. x are defined as follows:
x=Zx 5=
4.2 Values below the highest lower limit of detection are not included in the average.
4.3 If all values in the averaging group are less than the highest LLD, the highest LLD is reported.
4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.
4.5 In rounding off, the following rules are followed:
4.5.1.
If the number following those to be retained is less than 5, the number is dropped, and the retained numbers are kept unchanged. As an example, 11.443 is rounded oftto 11.44.
4.5.2.
If the number following those to be retained is equal to or greater than 5, the number is dropped and the last retained number is raised by 1
. As an example, 1 1.445 is rounded off to I I.45.
