1.0 INTRODUCTION

This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2017 for the Union Electric Company tuba 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 1 982.

The Callaway Energy Center consists of one 3565 MWt pressurized water reactor, which achieved initial criticality on October 2, 1984. 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 2017 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 2017 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 3.1 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 (TLDs).

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 Cailaway 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-131, 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-137, and cerium-144. 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 10% 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-144, and cesium-137 to the activity of the resulting debris are in the approximate ratio 4:1:0.03 (Eisenbud,1963).

The other group quantified consists of niobium-95, ruthenium-i 03 and -106, cesium-134, barium lanthanum-140, and cerium-141. 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 Procram 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 stations identified by the Land Use Census for the subject year. The control station continued to be collected. Samples are analyzed for iodine-131 and gamma-emitting isotopes.

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-131 and other gamma-emitting isotopes.

Feed crops (soybeans, sorghum, corn) are collected from locations FC-1 through FC-4. FC-1, FC-2 and FC-3 are located on Ameren property traversed by the discharge pipeline. The samples are collected at harvest and analyzed for tritium and gamma emitting isotopes. FC-4 is a control location, beyond the influence of plant operations. Feed crops are grown for animal feed and not for human consumption. The soybean field for sample FC-1 is planted by the Missouri State Department of Conservation (MODOC) to provide feed to wildlife living in the Reform Wildlife Conservation Area. MODOC did not plant the field this year and there was no crop to sample.

The waterborne pathway is monitored by sampling surface water, groundwater and drinking water, and bottom 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. 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 nine ponds is analyzed for tritium and gamma-emitting isotopes. The collection frequencies are either 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.

4

Potable well water samples are collected quarterly from the plant drinking water supply, neighboring property owners, and from the town of Portland, MO. The samples were analyzed for tritium and gamma-emitting isotopes.

River bottom sediment is collected semiannually at the plants intake (A) and discharge (C). The samples are taken from water at least 2 meters deep to prevent influence of bank erosion.

Shoreline sediments are collected semiannually in the same area as bottom sediment. These samples are collected within approximately 60 cm of the edge of the water. The samples are analyzed for gamma-emitting isotopes.

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, PR3, F6, PR7, W2, W3, and W4) and two control locations (M9. Wi) to monitor the terrestrial environment. The samples are analyzed for gamma-emitting isotopes.

3.3 Prociram Execution The program was executed as described in the preceding section with the following exceptions.

(1) Surface Water:

The rivet sampler at location SQl was discovered not functioning 4/5/1 7. This caused a missed grab sample for 4/4/17 due to a miscommunication between the Operations Department and the Radiation Protection Department.(CR 201701816). Compensatory grab sampling was initiated 04/06/17 until the compositor was repaired on 6/23/17. The cause of the malfunction was silting of the sample line and excessive silting in the intake pump bay containing the sample line. Unsafe river conditions and unavailability of qualified divers extended the condition beyond the 30 days stated in the action statement which requires that the condition be described in this report. (CR 201702981)

Flooding by the Missouri River at the town of Portland resulted in the loss of sampler S02 and an inability to safely obtain the required grab sample on 5/6/17 and 5/7/17 (CR 201702495). The sampler pump was destroyed by the flood waters and had to be replaced with a new pump.

SOl was out of service for 81 days in 2017 and S02 was out of service for 78 days.

(2) Ground Water:

Insufficient water was available from location Ui MW-47 for the 1/19/17 sampling event.

(3) Drinking Water:

No drinking water sample was available at location DWA-D01 beginning with the 4/25/17 sampling event due to the location being dropped from the program.

(4) Broadleaf Vegetation:

Edible broadleaf vegetation, collected at the five area gardens was available for harvest from May through October, 2077 with the following exceptions: Vegetation from location V-78 was missed for the April, May and June 2077 collections. This failure was determined to be a result of collection personnel utilizing outdated collection instructions. Collection personnel were coached on proper procedures using the official sample schedule document HTP-ZZ-07001 -DTI-REMP 5

SMPL-SCHED (CR2 01703581). Samples were not available at locations V-il, V-12 and V-16 in April due to the gardens not yet producing. Gardens at locations V-i 1 and V-i 6 were not producing in May. The garden at location V-i 6 was done producing before the August collection event(CR 201704053). No vegetables were available at location V-18 for the month of September. No samples were available tot locations V-li, V-16 and V-18 for the month of October.

See Table 5.5 The growing season is defined as April 1 through November 1 (ref: Hammer, Gregory R.)

although samples are rarely available prior to May 1. A vegetation sample unavailable after October 31 is not considered a missed sample.

(5) Inedible Crops:

Inedible crops were not collected at location FC-1 during the 2017 collection due to the field not being planted.

(6) Direct Radiation The first quarter TLD at location IDM-32 was discovered missing from its posted location. The third quarter TLD at location IDM-39A was also discovered missing from its posted location.

(7) Airborne Particulates and Iodine.

Air station B-3 was permanently shut down 12/28/16. The sampling equipment was removed and relocated to a new sampling location A-b. During the transition from station B-3 to station A-b the program was below the minimum number of air stations during the one week transition period (12/28/16-01/05/18) (CR 201700071). A new station, A-lU, was created and sampling began at new locations A-lU and A-il beginning 01/05/18. Station A-il experienced multiple loss of power conditions between 1/05/17 and 2/23/17. (CRs 201700198, 201700542, CR201700796, 2017000894, and 201700948.) The issue was eventually traced to the use of a GFCI outlet in conjunction with a surge suppressor. The surge suppressor shunts the voltage to ground; the GECI senses the ground voltage and trips as designed. The GFCI outlet was removed. There was a low sampling volume at location A-i 1 for the collection period ending 2/23/17 due to aforementioned equipment problems.(CR 201700948) There was no sample at location A-7 for the collection period ending 4/6/17 due to a power loss by the power provider. (CR 201701842) 3.4 Laboratory Procedures The iodine-131 analyses in milk were made using a sensitive radiochemical procedure involving separation of the iodine by ion-exchange, solvent extraction and subsequent beta counting.

Gamma-spectroscopic analyses were performed with HPGe detectors. Levels of iodine-131 in vegetation and concentrations of airborne iodine-i 31 in charcoal samples were also determined by gamma spectroscopy.

Tritium was measured by liquid scintillation.

Analytical Procedures used by Environmental, Inc. are on tile at the laboratory and are available for inspection. Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dept of Energy, Edition 28, 1997, U.S. Environmental Protection Agency for Measurement of Radioactivity in Drinking Water, 1980, and the U.S. Environmental Protection Agency, EERF, Radiochemical Procedures Manual, 1 984.

Environmental, Inc., Midwest Laboratory has a comprehensive quality control/quality assurance program designed to assure the reliability of data obtained. Details of the QA Program are presented elsewhere (Environmental, Inc., Midwest Laboratory, 2017). The QA Program includes 6

participation in Interlaboratory Comparison (crosscheck) Programs. Results obtained through Quality control samples and crosscheck program results are presented in Appendix A.

Environmental TLDs are processed by Stanford Dosimetry, LLC.

3.5 Program Modifications A vegetation sample was added at location V-i 8 on 2/13/17. Drinking water sample location DWA-D01 was removed because the property owner switched to county drinking water. The last collection occurred 01/30/1 7. Location DWA-D01 was replaced with new location DWA-23 (CR 201700835). The first collection at location DWA-23 occurred 04/25/1 7.

3.6 Detection and Reporting Limits Table 5.3 gives the minimum required detection limits for radiological environmental sample analysis. For each sample type, the table lists the detection level for each isotope. The lower limit of detection (LLD) used in this report is described in NRC Regulatory Guide 4.1 Rev. 1 Program for Monitoring Radioactivity in the Environs of Nuclear Power Plants (April, 1975) and the NRC Radiological Assessment Branch Technical Position, Rev. 1, An Acceptable Radiological Environmental Monitoring Program (November, 1979).

3.7 Land Use Census The Land Use Census is performed annually during the growing season. In 2017, the survey was conducted within a five mile canvassing radius of the Callaway Energy Center. The area around the plant was divided into 16 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. All residents who were identified in the summary report to the census were contacted by telephone or verified by Callaway County GIS aerial photography.

The field inspection of the sectors was conducted on October 9, 2017. 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 Energy Center to the sample location.

The following revisions are reflected in the 2017 report. In Sector A, Anton Leisinger is the closest resident in this sector. There is no broadleaf vegetable garden replacement in this sector. In Sector D, Frank Timmermeier is the closest resident. In Sector E, James Reynolds is the closest resident.

Finally in Sector G, Phillip Baumgarth is the closest resident.

During the survey a water well was identified at 9180 County Road 457, Steedman, MO 65077. This well is owned by Leonard Farley and was added to the environmental monitoring program since it is within the Callaway Energy Center pipeline corridor. No irrigation uses of the Missouri River, within 10 miles downstream, were identified during the survey. The Missouri Department of Natural Resources confirmed that no new drinking water intakes have been located along the Missouri River within ten (10) river miles downstream from the plant.

4.0 RESULTS AND DISCUSSION All collections and analyses were made as scheduled, except for the listing 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 2017 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 Daiichi nuclear accident occurred March 11, 2011. There were no reported accidents involving significant release to the environment at nuclear reactor facilities in 201 7 but there was a minor release of Ru-106 traced to a possible incident in central Asia the week of September 19 through 26, 2017. The last reported atmospheric test was conducted on October 16, 1980 by the Peoples Republic of China. There were no reported atmospheric nuclear tests in 2017.

4.2 Program Findings Airborne Particulates and Iodine No gamma emitting isotopes were identified other than naturally occurring Be-7.

There was no 1-131 activity detected in any of the charcoal canister samples.

Air sampling for 2017 indicates no radiological effects of plant operation.

Direct Radiation tTLD5)

Forty-four gamma sensitive ILDs were placed in 16 sectors around the Callaway site.

Measurements from forty-one indicator locations averaged 15.5 mrem/quarter and the three control locations averaged 14.8 mrem/quarter. Readings ranged from 11 .1 to 18.0 mrem /quarter, with the highest from the control location CA-IDM-27, averaging 17.1 mrem/quarter. The differences are statistically insignificant. The TLD readings were consistent with the results for the years 2000 through 2016 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 measureable neutron dose and there was no effect from the ISFSI in 2017.

Milk There are no milk indicator stations. No iodine-131 was detected in samples from the control station. No gamma-emitting isotopes, with the exception of naturally occurring potassium-40, were detected in milk. Milk data for 2017 show no radiological effects of plant operation.

Broadleaf Vegetation There was no 1-131 activity detected in broadleaf vegetation samples. No gamma-emitting isotopes were detected in broadleaf vegetation samples excepting naturally occurring 8

potassium-40. Vegetation data for 2017 show no radiological effects of plant operation.

N on-Food Crops Soybean samples were analyzed for tritium and gamma-emitting isotopes. No tritium activity was detected. No gamma-emitting isotopes, excepting naturally occurring potassium-40, were detected in non-food crops.

Fish Edible portions of fish were analyzed by gamma spectroscopy. No gamma-emitting isotopes, excepting naturally occurring potassium-40, were detected in fish.

Soil Cesium-137 activity was detected at fourteen of the eighteen sample locations at an average concentration of 238 pCi/kg dry. 300 pCi/kg dry was the average activity for the ten of fourteen positive indicator locations. All four control samples were positive for Cesium-i 37 with an average activity of 83 pCi/kg dry. The cesium-137 activity is consistent with levels observed from 1999 through 2016; these levels are attributable to the deposition of fallout from previous decades.

Surface Water Low level tritium was detected in four of the twelve samples collected at the downstream location S02 at an average concentration of 315 pCi/L. These results are consistent with pre- outage samples taken in previous years. There was no tritium detected in the remaining eight samples from S02. No gamma-emitting isotopes were detected.

Surface Water, Ponds Eighteen pond samples were analyzed for 2017. No tritium activity or gamma activity was detected.

Drinking Water Wells (potable water)

Fifty-nine samples from sixteen different locations were analyzed for tritium and gamma-emitting isotopes. No tritium or gamma-emitting isotopes were detected.

Wells and Ponds (non-potable water)

Groundwater samples from deep wells F-05 and F-i 5 were analyzed for tritium and gamma-emitting isotopes. There were no tritium or gamma emitting isotopes detected.

Wells MW-31, MW-34, MW-36, MW-39, MW-47, MW-58, and MW-59 were installed during the 2014 LSI (the 2014 LSI is described in detail in the Callaway Energy Center 2014 Annual Radioactive Effluents Release Report). These wells continue to monitor the natural attenuation of tritium which decreased significantly during 2015 and continued to decrease in 2016 and decreased again in 201 7. Tritium activity was detected in 18 of 27 samples from these wells. The highest concentration was measured in MW-31 which peaked at 1688 pCi/L in January. By years end, the concentration in MW-31 had fallen to 278 pCi/L. The average concentration among positive results for these wells was 776 pCi/L. this decline has been steady since the December of 2016. The contamination is being remediated by monitored natural attenuation. There are no active leaks.

Wells GWS, 936, 937B, 937D, 939R, 940, 941 and IFSFI Sump are located in the Plant Protected Area, adjacent to the power block. Tritium activity in these wells is believed to be the result of washout from gaseous effluents. GWS is a drawdown sump that pumps water from the area adjacent to the power block and is especially sensitive to washout. The current tritium is 9

consistent with past years.

The low level tritium activity observed in wells MW-014, MW-018 and MW-019 is due to residual low level contamination from moisture carryover during normal operation of air release valves (ARVs) in manholes 5 and 6B on the now-retired discharge pipeline. The pipeline was replaced in 2008 and there has been no new contamination of this area since then. The existing contamination is being remediated by monitored natural attenuation. There are no active leaks and the results are consistent with 2015 and 2016.

Sediments Samples of shoreline and bottom sediments were collected in June and October 2017 at both an indicator and a control location and analyzed for gamma-emitting isotopes. Cesium-137 was detected in one of the two bottom sediment samples at a concentration of 98 pCi/kg dry weight, and was detected in one of the two shoreline sediments at concentration of 38 pCi/kg dry weight.

Both detections were from the indicator location collected in October. These results are consistent with results from previous years. There were no other gamma-emitting isotopes detected excepting naturally occurring potassium-40 in any of the sediment samples.

The complete appendix is included in March, June, September and December monthly progress reports only.

Appendix A I nterlaboratorv/ Intralaboratorv Comparison Proram Results Environmental Inc. Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental type samples containing concentrations of radionuclides known to the issuing agency 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 Resources 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 (TLDs), 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 in-house 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 in-house blank samples for the past twelve months. Data for previous years available upon request.

Table A-5 lists analytical results from the in-house duplicate program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors.

Complete analytical data for duplicate analyses is available upon request.

The results in Table A-6 were obtained through participation in the Mixed Analyte Performance Evaluation Program.

Results in Table A-7 were obtained through participation in the MRAD PT Study Proficiency Testing Program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).

Attachment A lists the laboratory precision at the 1 sigma level for various analyses. The acceptance criteria in Table A-3 is set at +/- 2 sigma.

Out-of-limit results are explained directly below the result.

Results are reported in units of Bq/kg (soil). Bq/L (water) or Bq!total sample (fillers, vegetation).

Laboratory codes as follows. MAW (waler), MAAP (air tilter(. MASO (soil), MAVE (vegetation(.

MAPEP results are presented as the known values and expected laboratory precision (I sigma, 1 determination) and control limits as defined by the MAPEP. A known value of zero indicates an analysis was included in the testing series as a false positive. MAPEP does not provide control limits.

Decimal point was misplaced while performing a unit conversion. The result is within control limits when the proper unit conversion is performed.

Provided in the series for sensitivity evaluation. MAPEP does not provide control limits.

Sample was reanalyzed in duplicate with acceptable results. Original plating was interior to platings obtained during reanalysis.

It is believed that isotopic tracer was not accurately quantified due to poor resolution of its peak.

Data were erroneously submitted in units of Bq/g. All results pass MAPEP criteria when evaluated in units of Bq/Kg.

Laboratory is not currently offering analysis for Am-241 in Air Particulate samples.

Laboratory codes as follows: ERW twatert, ERAP (air tillert, ERSO (soil), ERVE (veoetatlont. Results are reported in units ot pCi/L, except tor air filters (pCi/Filter), vegetation and soil (pCi/kgl.

Results are oresented as the known values, expected laboratory orecision (2 sigma, 1 determination) and control limits as provided by ERA.

Fe-55 analysis result was outside the acceptable range. Recounting the sample disk for 1000 minutes resulted in 254 +/- 364 with an LLD calculation of < 342. Insufficient sample was available after performing other required analyses on the sample to quantify the activity wifh an uncertainty tesa then the activity.

ERA appears to have appl:ed the standard materiel to the filter in a oettern closer to the center of the filter comoared to previous studies end different from the filter efficiency utilized by the laboratory. This likely caused the efficency used the calculation to be understated and the result obtained by the laboratory to be overstated. For comparison the in-house spike for gross beta in AP Itable A-3 SPAP-740 2:28i17( was acceptable with a ratio of 0.g4 of lab result to known.

Analysis result tor Plutonium-23g.240 was below the lower limit of acceptance.

Samples were reanalyzed in duplicate with acceptable results tor each. Driginel analysis had poor resolution possibly due to a poor etctroplsting and is suspected in contributing to poor results.

Analysis result for U-233/234 was below the lower limit of acceptance.

The reanalysis result for U-233/234 wee within the acceptance limits and U-238 reanalysis result wss closer to the known value.

Driginal analysis had poor resolution possibly due to 5 poor electroplating and is suspected in contributing to poor results.

Fe-55 analysis result was outside acceptable range.

Result ot recounting was acceptable. Using available aligupt after dividing sample tar other analyses leaves insufficient sample to reliably determine the activity present in sample.

APPENDIX B. DATA REPORTING CONVENTIONS Data Reportinp Conventions 1 .0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.

2.0. Sinole Measurements Each single measurement is reported as follows: x+/-s where: x = value of the measurement; s = 2 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 4.66ri 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 +/- s1 and x2 +/- s2 Reported result: x +/- s; where x = (1/2) (x1 ÷ x2) and s (1/2) Js +

3.2. Individual results: <L1 , <L2 Reported result: < L, where C = lower of L1 and L2 3.3. Individual results: x +/- s, <L Reported result: x +/- s if x C; < L otherwise.

4.0. Computation of Averapes 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 and standard deviation s of a set of n numbers x1, x2 . . . x,1 are defined as follows:

W2 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 oft to 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, 11.445 is rounded off to 11.45.

Appendix C. NON-RADIOLOGICAL MONITORING PROGRAM 1.0. Introduction Union Electric Company Callaway Plant, d.b.a. Ameren Missouri Callaway Energy Center, in accordance with federal regulations and a desire to maintain the quality of the local environment around Callaway Plant has implemented an Environmental Protection Plan, (EPP) contained in Appendix B of the Callaway Plant Operating License.

The objective of the EPP is to provide for protection of non-radiological environmental values during operation of the Callaway Plant.

This report describes the conduct of the EPP for the Callaway Plant during 201 7.

2.0. Unusual or Important Events No unusual or important events reportable under the EPP Section 4.1 were identified during 2017.

3.0. EPP Non-compliances During 2017, there were no non-compliances with the EPP.

4.0. Nonroutine Reports There were no nonroutine reports submitted in accordance with the EPP, Section 5.4.2 in 2017.

5.0. Plant Design and Operation Environmental Evaluations.

This section lists all changes in the plant design, operation, tests or experiments installed during 2017, which could have involved a potentially significant unreviewed environmental question in accordance with section 3.1 of Appendix B.

During 2017, two plant changes were completed that could have involved a potentially significant unreviewed environmental question. The interpretations and conclusions regarding these plant changes along with a description of the change and activity are presented below.

MP 1 6-0035 Replacement of Existing Transformer XPBJJ7 at the Callaway Intake Facility Description of Change; MP 16-0035 covers the replacement of existing transformer XPB1 17 at the Callaway Plant intake facility. The new transformer contains 1667 gallons of refined mineral oil (approximately 588 gallons more than the original transformer). The original transformer was located above a permanent rock filled concrete pit to contain the total volume of oil should a leak develop. Rock was removed from this pit to allow additional volume to contain the 1667 gallons should a leak occur in the new transformer. The containment pit also contains a new double grating with an absorbent rock layer.

Evaluation of Change:

As part of the Final Environmental Evaluation, both the Environmental Report (ER) and Final Environmental Statement for the Operating License (FES-OL) were reviewed for any previously evaluated adverse environmental impacts and any new adverse environmental impacts not previously evaluated. No adverse environmental impacts were identified. Although the replacement transformer contains a larger volume on mineral oil, the concrete containment located under the transformer was redesigned to contain the entire volume ot the new transformer. Therefore, should a leak develop, oil remains contained within the concrete pit and there is no increased risk of this oil being discharged to the Missouri River.

This change does not involve an unreviewed environmental question and NRC approval was not required.

RFR 160765 New Coagulants/Flocculants for Raw Water Systems Description of Change:

This change involves the testing and use of multiple flocculants/coagulants at the Callaway Water Treatment Plant (WTP) to optimize solids removal in makeup water withdrawn from the Missouri River. These products may be utilized at the Water Treatment Plant (WTP) rapid mixing unit or splitter box to treat makeup to raw water systems including the circulating water C-2

system, service water system, and essential service water system. Callaway has previously used BULAB 5013, Dimethyl Ammonium Chloride (DADMAC) a similar polymer/coagulant for solids removal. In addition BULAB 5086 and BULAB 5011 P have previously been approved for use. This change allows use of the following new products or a blend of these products (BULAB 5086, BUFLOC 5459, BULAB 5535, BULAB 5900, BULAB 5175, and BULAB 5534) to reduce solids carried to the plant raw water systems. As a result, it is expected that suspended solids will also be reduced in plant discharges from NPDES Outfalls 002 and 076. The new products are less toxic to aquatic life and will be used at the same treatment concentrations as previously used for BULAB 5013 (approximately 1-3 ppm).

Evaluation of Change:

As part of the Final Environmental Evaluation, both the ER and FES-OL were reviewed for any previously evaluated adverse environmental impacts and any new adverse environmental impacts not previously evaluated. No adverse environmental impacts were identified. Missouri DNR approval or NPDES permit changes were not required as similar coagulants/ organic polymers were previously approved by the state. In addition, use of coagulants/organic polymers at the WTP was included in the last Callaway NPDES Permit re-application. Each of the products evaluated contain a similar water-soluble cationic polymer and will be maintained at the same concentration range. Aquatic toxicity data was reviewed for each of the products evaluated and each product was found to have a less toxic 48-hour LC5O and 96 hour0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> LC5O than BULAB 5013. Therefore, use of the approved products evaluated for use at the WTP as described above should have no adverse effect on the environment.

This evaluation concluded that this change to utilize any of the following coagulants/flocculants (BULAB 5086, BUFLOC 5459, BULAB 5535, BULAB 5900, BULAB 5115, BULAB 5534) for solids removal at the WTP does not involve an unreviewed environmental question and NRC approval was not required.
