1.0 INTRODUCTION

This report presents an analysis of the results of the Radiological Environmental Monitoring Program (REMP) conducted during 2012 for the Union Electric Company (dba Ameren Missouri Corp.),

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, 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 2012 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 herein described.

Results for the year 2012 are summarized and discussed.

For the year, the Callaway Energy Center was operated in compliance with Off Site Dose Calculation Manual (ODCM) and Radiological Effluent Controls (REC) requirements. Comparison of results for 2012 show no significant differences to the historical data. 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.

Short-lived radioactive elements released into the environment following the Fukushima Daiichi incident, March 11, 2011, are no longer detectable in the background. It is possible that a slight increase in soil and sediment background activity could be observed, attributable to the release of longer-lived isotopes, e.g. Cs-134 and Cs-137.

3 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. Ambient gamma 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.

In interpreting the data, effects due to operation of the Callaway Energy Center must be distinguished from those due to other sources.

A major interpretive aid in assessment of these effects is the design of the monitoring program at the Callaway Energy Center, based on the indicator-control concept. 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.

An additional interpretive technique involves analyses for specific radionuclides present in the environmental samples collected from the Callaway site. 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-103 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 calibration 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.

4 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, direction, and sector 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 particulates and airborne iodine samples are collected by continuous pumping, at five locations. The airborne particulates are collected on glass fiber filters and the airborne iodine through an activated charcoal cartridge. 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. 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.

Soybeans 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.

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 (S01).

Onsite surface water from eleven ponds is analyzed for tritium and gamma-emitting isotopes. The collection frequencies are either semiannually or quarterly.

To monitor possible sources of ground water contamination due to plant operations, non-potable ground water is collected monthly or quarterly from 48 well locations both onsite and along the discharge pipeline. The samples are analyzed for tritium and gamma-emitting isotopes.

Potable well water samples are collected quarterly from the plant drinking water supply, neighboring property owners, and from the town of Portland, MO.

River bottom sediment is collected semiannually at the plant's 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 two feet of the edge of the water. The samples are analyzed for gamma-emitting isotopes.

5 3.2 Program Description (continued)

Another pathway considered is direct ambient gamma radiation. This exposure is monitored by thermoluminescent dosimeters (TLDs), at forty-three locations in and around the Callaway site.

The TLDs are placed in 16 sectors around the plant as specified in the ODCM-RECS. Three locations are designated as controls (IDM-26, IDM-27 and IDM-60). TLDs are placed at each location and exchanged and analyzed quarterly.

To monitor the terrestrial environment, soil is collected annually from seven indicator locations (F2, PR3, F6, PR7, W2, W3, and W4) and two control locations (M9, W1). The samples are analyzed for gamma-emitting isotopes.

Additional sampling for soil, surface and ground water was conducted in 2012. Results are included in Part II, App. A.

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

(1) Surface Water:

The surface water samples are composites of daily collections by automatic river sampler from two locations, S01 and S02. The sampler at S01 was out-of service approximately 15 days in 2012. The sampler at S02 was 100% operable. During sampler downtime, composites of daily grab samples are prepared and submitted for analysis.

(2) Ground Water:

Ground water collection has been intermittent for monitoring wells U1MW-28 and MW-939 since installation in 2010.

For the first quarter, 2012, a small sample (<100 ml.) was collected from location U1MW-28, and analyzed for tritium and gamma emitting isotopes. The second quarter sample was analyzed for tritium only, since there was insufficient volume for a gamma isotopic analysis.

No sample was available during the third and fourth quarters. This well should normally be dry, since the area is rocky, with a shallow overburden of clay. U1MW-28 was installed specifically to monitor for leakage from the single vacuum breaker on the discharge pipeline.

There was only one collection from MW-939 in 2012. The well was dry from February through July due to lack of rain and draw down of the water table from the Groundwater Sump (GWS).

The well was drilled approximately 10 feet bgs to monitor piping at that depth. In August, 2012, a replacement well, MW-939R, was installed about 3 feet from MW-939 at a depth of 25 feet bgs. MW-939 was closed out at that time.

The January CTBD sample was lost during shipment and could not be located. CTBD was subsequently eliminated from the program.

The Unit 2 Pond was eliminated from the program prior to the October sampling. The pond was drained to allow for site evaluation, prior to construction of a new plant facility in that location.

6 3.3 Program Execution (continued)

(3) Vegetation:

No area garden produced vegetation samples until the May collection. Location V-11 reached the end of its season with the October sampling. V-9 and V-12 ceased production after the November sampling. Location V-16 did not produce vegetation until June and was harvested prior to the October sampling. Missing samples during the periods when the gardens were producing are shown in Table 2.0. Most missing vegetation samples were due to the effects of drought on area gardens.

The growing season is defined as April 1 through October 31 (ref: Hammer, Gregory R.). A vegetation sample unavailable after October 31 is not considered a missed sample.

(4) Non-food Crops Fields at stations FC-1, FC-2, and FC-3 were not planted this year, therefore there were no soybeans to sample.

(5) Air Iodine and Particulates Air iodine and air particulate station A-8 was shut down on September 6, 2012, due to safety concerns resulting from a damaged electrical cord. The unsafe condition was repaired on September 10, 2012 and the sampler returned to service. Samples collected from station A-8 for the week ending September 13 had lower volume, due to the reduced run-time. Wiring at the remaining air sampling stations (A-1, A-7, A-9, and B-3) was also repaired, with approximately a one hour interruption in service for each station.

(6) Direct Radiation:

The TLD and fade dosimeters placed at location IDM-40 were missing for the 2nd quarter.

In the third quarter, dosimeters from locations IDM-21, IDM-36 and IDM-49 were missing.

The TLDs were replaced. Vandalism is suspected in all cases.

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-131 in charcoal samples were also determined by gamma spectroscopy.

Tritium was measured by liquid scintillation.

Analytical Procedures used by Environmental, Inc. are on file at the laboratory and are available for inspection. Procedures are based on those prescribed by the Health and Safety Laboratory of the U.S. Dep't 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, 1984.

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, 2012). The QA Program includes 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.

7 3.5 Program Modifications

1. Sampling of surface water from the Cooling Tower Blowdown (CTBD) was discontinued in 2012 (CAR 201200833). The replacement of the discharge pipeline eliminated the recirculation of tritium in the river and the sample was no longer necessary.

2. Sampling of surface water from the Unit 2 pond (CA-SWA-Unit 2) was discontinued in the fourth quarter, 2012. The Unit 2 pond was drained for geotechnical borings and sampling to support construction in that location.

3. Ground water collection has been intermittent from well site CA-WWA-939 since it was added to the program in 2010. The well was only 10 deep. The replacement well CA-WWA-939R is approximately 3 feet from CA-WWA-939 and 25 feet deep. Sample collection began in August, 2012.

4. For the 2012 growing season, vegetation sampling location V16 replaced station V15, due to a history of poor performance.

5. The soil control station (V3) was replaced by station M9 (CAR 201108365), due to the death of the property owner.

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" and the NRC Radiological Assessment Branch Technical Position, Rev. 1, November 1979, "An Acceptable Radiological Environmental Monitoring Program".

3.7 Land Use Census The Land Use Census is performed annually during the growing season. In 2012, the survey was conducted within a five mile canvassing radius of the Callaway Energy Center. The location of the nearest resident, milking animal, and broadleaf vegetation garden greater than 50 square meters was identified by contacting residents by phone, mail and/or in field surveys for each of the sixteen meteorological sectors using the midpoint of the two units.

The Land Use Census was completed on October 12, 2012. 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, determined by a Global Positioning System (GPS) receiver.

The census includes identification of drinking water wells along Mud Creek, Logan Creek and along the discharge pipeline corridor. No new drinking water wells were identified in 2012.

No irrigation or drinking water intakes were found within 10 river miles downstream of the plant discharge point.

8 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 2012 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 There were no reported accidents involving significant release to the environment at nuclear reactor facilities in 2012. The Fukushima Daiichi nuclear accident occurred March 11, 2011.

There were no reported atmospheric nuclear tests in 2012. The last reported atmospheric test was conducted on October 16, 1980 by the Peoples Republic of China.

4.2 Program Findings Results obtained show background levels of radioactivity in environmental samples collected beyond the plant property boundary in 2012. Tritium was identified in some groundwater samples collected within the Plant Protected Area and on Ameren property in the Missouri River alluvial plain. In no instances were REMP threshold reporting levels exceeded.

Airborne Particulates The five air particulate sampling stations (A1, A7, A8, A9, and B3) are indicator locations. Station A-9 is located in Reform, MO, the community with the highest D/Q, station A-7 is on the outskirts of Fulton, Missouri, approximately 9.5 miles from the plant.

Gamma spectroscopic analysis of the air particulate filters yielded similar results for all locations.

In 106 of the 264 samples tested, Beryllium-7 measured above an LLD value of 0.17 pCi/m3, with an average activity of 0.23 pCi/m3. Beryllium-7 is produced continuously in the upper atmosphere by cosmic radiation. No gamma emitting isotopes of plant origin were identified.

Airborne Iodine There was no I-131 activity detected in weekly collections of charcoal canister samples. All measurements were below the required lower limit of detection (LLD) of 0.070 pCi/m 3.

Direct Radiation (TLDs)

Forty-three TLDs were placed in 16 sectors around the Callaway site. Measurements from forty indicator locations averaged 16.0 mrem/quarter and the three control locations averaged 15.3 mrem/quarter. Readings ranged from 10.6 to 18.6 mrem /quarter, with the highest from the control location CA-IDM-27, averaging 17.7 mrem/quarter. The differences are statistically insignificant.

The TLD readings were consistent with previously accumulated data and no effect from plant operation was identified.

Enclosure to ULNRC-05987 14 of 103

9 4.2 Program Findings (continued)

Milk Iodine-131 results were below the detection limit of 0.5 pCi/L in all samples.

No gamma-emitting isotopes, excepting naturally occurring potassium-40, were detected in milk.

Average potassium-40 activity measured 1186 pCi/L and ranged from 977-1477 pCi/L.

In summary, milk data for 2012 show no radiological effects of plant operation.

Vegetation There was no I-131 activity detected in broadleaf vegetation samples. Measurements were below an LLD level of 41.4 pCi/kg wet weight in all samples.

Except for naturally-occurring potassium-40, which was observed in all vegetation samples, gamma-emitting isotopes were below detection limits. No effect from plant operation is indicated.

Non-Food Crops Soybeans were collected in September and October, 2012, and analyzed for tritium and gamma-emitting isotopes. One sample of corn was collected from the control location (FC-4)

No tritium activity was measured above a detection level of 161 pCi/L in any of the samples.

The potassium-40 activity ranged from 3,311-14,153 pCi/kg wet weight. All other gamma-emitting isotopes measured below detection limits.

No effect from the plant operation is indicated.

Fish Edible portions of fish were analyzed by gamma spectroscopy. The potassium-40 levels measured were almost identical at indicator and control locations (2,908 and 2,897 pCi/kg wet, respectively).All other gamma-emitting isotopes measured below detection limits.

No plant effect on the fish population is indicated.

Soil Cesium-137 activity was detected at both indicator and control locations, at average concentrations of 333 and 114 pCi/kg dry, respectively. The cesium-137 activity is similar to or less than levels observed from 1999 through 2011, these levels are generally attributable to the deposition of fallout from previous decades.

Naturally-occurring potassium-40 averaged 11,985 pCi/kg dry weight.

Analysis results for soil samples in 2012 were consistent with previously accumulated data and no plant operational effects were identified.

Enclosure to ULNRC-05987 15 of 103

10 4.2 Program Findings (continued)

Surface Water Slight tritium activity above the detection limit of 177 pCi/L was observed in two of the twelve samples collected from the downstream location S-02. The measurements averaged 363 pCi/L.

Gamma-emitting isotopes measured below detection limits and were consistent with previously accumulated data.

Surface Water, Ponds To monitor possible sources of groundwater contamination due to plant operations, eleven onsite surface water locations (SWA) are included in the permanent REMP. Tritium was detected in one of four samples from the UHS pond at a level of 233 pCi/L. All other sample results measured below detection level. Traces of H-3 activity in these ponds is believed to be the result of washout from gaseous effluents.

Gamma-emitting isotopes measured below detection limits. No plant operational effects were identified.

Drinking Water Wells (potable water)

In addition to potable ground water from wells D-01 and PW-01, the REMP includes nine additional potable water wells from adjacent properties and one additional potable water well from the town of Portland, MO. The samples were analyzed for tritium and gamma-emitting isotopes.

No tritium activity was measured above a detection level of 152 pCi/L in any of the samples. All gamma-emitting isotopes were below detection limits.

Analysis results for drinking water samples were consistent with previously accumulated data and no plant operational effects were identified.

Wells (non-potable water)

Ground water from wells F-05 and F-15 was tested for tritium and gamma-emitting isotopes. Both tritium and gamma-emitting isotopes measured below detection levels.

Forty-six additional indicator ground water locations, on-site and along the discharge pipeline, are included in the REMP. Tritium activity (above a detection limit of 178 pCi/L) was detected in 36 of the 280 samples tested, with an average activity of 366 pCi/L. The highest concentrations were measured at the Ground Water Sump (CA-WWA-GWS), with an average activity of 794 pCi/L.

Wells OW-4, OW-5, GWS, 936, 937A to 937F, 938, 939, 940 and 941 are located in the Plant Protected Area, adjacent to the powerblock. Tritium activity in these wells is believed to be the result of washout from gaseous effluents.

The low level tritium activity observed in wells MW-014, MW-017, MW-018 and MW-019 is due to residual low level contamination of the area down gradient from manholes 5 and 6B. The contamination was caused by moisture carryover during normal operation of air release valves (ARVs) in the now-retired discharge pipeline. The exhaust of the ARVs was secured in 2007, and the pipeline was replaced in 2008. The new discharge pipeline has no ARVs and only a single vacuum breaker, which is completely contained to prevent possible leakage to the ground water. The old pipeline has been abandoned in place. The contamination is being remediated by monitored natural attenuation. There are no active leaks.

Enclosure to ULNRC-05987 16 of 103

11 4.2 Program Findings, Wells and Ponds (non-potable water, continued)

Wells have been established along the pipeline corridor to monitor the old pipeline and to ensure there is no leakage from the new pipeline. Monitored natural attenuation will be utilized to remediate the low level residual tritium contamination.

Samples were also analyzed for gamma-emitting isotopes. No gamma-emitting activities were detected above the respective LLDs.

Sediments Bottom sediments were collected in May and October, 2012, and analyzed for gamma-emitting isotopes. A low level of cesium-137 was detected in both of the control samples with an average concentration of 78 pCi/kg dry weight and one of the two indicator samples at a concentration of 46 pCi/kg dry weight. Potassium-40 activity ranged from 12,617 to 13,743 pCi/kg dry weight and averaged 13,060 pCi/kg dry weight.

Shoreline sediments were also collected in May and October, 2012. Trace cesium-137 activity was detected in the two control samples at a concentration of 43 pCi/kg dry weight, but measured below detection limits at the indicator location. Potassium-40 activity ranged from 12,569 to 13,930 pCi/kg dry weight and averaged 13,551 pCi/kg dry weight.

Potassium-40 is a naturally occurring isotope. The slight cesium-137 activities observed are indicative of the influence of fallout deposition. All other gamma-emitting isotopes were below detection limits. No effect from the plant operation is indicated.

NOTE:

Environmental Inc., Midwest Laboratory participates in intercomparison studies administered by Environmental Resources Associates, and serves as a replacement for studies conducted previously by the U.S. EPA Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. Results are reported in Appendix A. TLD Intercomparison results, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program results are also reported. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.

January, 2012 through December, 2012 APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS Enclosure to ULNRC-05987 40 of 103

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-1 were obtained through participation in the environmental sample crosscheck 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 International Intercomparison of Environmental Dosimeters, when available, and internal laboratory testing.

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 REMP specific 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 environmental sample crosscheck program administered by Environmental Resources Associates, serving as a replacement for studies conducted previously by the Environmental Measurement Laboratory Quality Assessment Program (EML).

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

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.

c MAPEP results are presented as the known values and expected laboratory precision (1 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.

d Investigation was inconclusive, there was not enough sample for reanalysis. ERA results (A-7) for the same matrix were acceptable.

e No errors found in calculation or procedure, original analysis result; 0.010 +/- 0.010 Bq/filter.

f Reanalysis results were within limits, but low. ERA results (A-7) for the same matrix were acceptable.

The efficiency factor was recalculated for the second round of MAPEP testing. Original analysis results 55.8 +/- 12.6 Bq/L.

g Result of reanalysis; 6.74 +/- 0.15 Bq/sample. Gamma emitters for the vegetation matrix exhibited a high bias, only Co-57 exceeded acceptance limits. Recounted using a geometry more closely matched to the MAPEP sample size.

h Result of reanalysis; 0.070 +/- 0.013 Bq/filter.

i Result of reanalysis; 0.013 +/- 0.005 pCi/filter. A larger sample size was used to reduce the counting error.

j Result of reanalysis 1.07 +/- 0.06 pCi/L. The analyses of the MAPEP sample matrix resulted in recovery factors greater than 100%.

A correction was made using recovery based on analysis of blank samples. A new tracer solution is on order, future samples for MAPEP testing will include batch spike and blank samples.

APPENDIX B. DATA REPORTING CONVENTIONS Data Reporting 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. Single 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 4.66 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) 2 2

2 1

s s +

3.2.

Individual results:

< L1, < L2 Reported 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 of Averages 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... xn are defined as follows:

x = 1 n x s =

(x-x )2 n-1 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 off 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.

C-1 Appendix C. NON-RADIOLOGICAL MONITORING PROGRAM 1.0, Introduction Union Electric Company, d.b.a. Ameren Missouri, in accordance with federal regulations and a desire to maintain the quality of the local environment around the Callaway Energy Center has implemented an Environmental Protection Plan, (EPP) contained in Appendix B of the Callaway Energy Center Operating License.

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

This report describes the conduct of the EPP for the Callaway Energy Center during 2012.

2.0. Unusual or Important Events No unusual or important events reportable under the EPP Section 4.1 were identified during 2012.

C-2 5.0. Plant Design and Operation Environmental Evaluations This section lists all changes in the plant design, operation, tests or experiments installed during 2012, which could have involved a potentially significant unreviewed environmental question in accordance with section 3.1 of Appendix B.

During 2012, one plant change 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 11-0004 - Ultimate Heat Sink Temperature Issue Solution Description of Modification:

Modification MP 11-0004 approved operational changes and minor equipment variations to address a temperature issue with the Ultimate Heat Sink (UHS). This modification allows the UHS level to be maintained at a maximum level of 18 feet as was originally designed with the spillway at 186. The normal UHS operating band was reset at 17 and 1710. This provides a 2 band (for instrument error) before reaching the pond level alarm set at 18 (alarm provides indication in the control room). In addition to the pond level changes, the UHS fan speed indication will be modified to ensure fan speed can be determined in the control room. The UHS Cooling Tower fan and bypass valve control circuitry will be modified to operate off of the essential service water (ESW) return line temperature at the onset of a Design Basis Accident (DBA) and to operate off of the ESW supply line temperature four hours into a DBA. The swap-over will be manually performed from the Control Room.

Evaluation of Change:

Callaways NPDES Permit MO-0098001 does not allow discharges from the UHS spillway. Outfall 017 (the Ultimate Heat Sink) is identified as a no discharge outfall. If the UHS overflowed it would discharge to stormwater Pond Outfall #011 and would be identified as a noncompliance of the NPDES Permit. Operation at the maximum level of 18 was evaluated and determined that it would take a sustained wind of 40 mph from the true southwest to produce waves of 8.4 which would be required to push a small quantity of water over the spillway. Winds from other directions would have much less risk of overflow or no risk of overflow. The highest sustained winds recorded during the past two years at Callaway were approximately 30 mph. Therefore, it was determined Enclosure to ULNRC-05987 60 of 103

C-3 that any risk of overflow from the UHS operating at a maximum level of 18 is extremely small.

5.0. Plant Design and Operation Environmental Evaluations Evaluation of Change (continued):

As part of the Final Environmental Evaluation, both the ER and FES-OL were reviewed for any previously evaluated adverse environmental impacts and any adverse environmental impacts not previously evaluated. No environmental impacts were identified as the modification changes would return the UHS pond to its original operating design. The only possible impact is to the NPDES Permit due to a slightly higher risk for a discharge from the UHS to stormwater pond Outfall #011. This would result in a noncompliance of the Callaway NPDES Permit; however, the risk of any overflow or spillage from the UHS is extremely small as described above.

The evaluation concluded that operational changes and minor equipment variations to address a temperature issue with the UHS does not involve an un-reviewed environmental question.
