1.0 Executive Summary This Annual Radiological Environmental Operating Report describes the Union Electric Company, Callaway Plant Radiological Environmental Monitoring Program (REMP), and the program results for the calendar year 2005. It is submitted in accordance with section 5.6.2 of the Callaway Plant Technical Specifications.

Section 2.0 describes the Radiological Environmental Monitoring Program. Included is the identification of sampling locations, descriptions of sampling and analysis procedures, analysis results, data interpretations, and program modifications.

Quality assurance results, sampling deviations, unavailable samples, and program changes are also discussed.

Section 3.0 describes the Non-Radiological Monitoring Program. Included are any unusual or important events, Environmental Protection Plan noncompliance, non-routine reports, and plant design and operational environmental evaluations.

During 2005 the Callaway Plant operated in compliance with the Offsite Dose Calculation Manual (ODCM) requirements.

Comparison of results for 2005 to preoperational data and data from previous years show no significant differences.

Results from the REMP indicate the Callaway Plant has had no significant radiological impact on the health and safety of the public or on the environment.

~- 2.0 Radiological Monitoring Program 2.1 Introduction This report presents an analysis of the results of the REMP conducted during 2005 for Union Electric Company, Callaway Plant.

The radiological environmental monitoring program began in April 1982.

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 Callaway Plant.

Callaway Plant consists of one 1239 MWe 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 Riverflows bythe site in an easterly direction approximately five miles south of the site at its closest point.

2.2 Program Design The sample locations, frequency of sampling, and sample analysis requirements originate from the Callaway Plant Off Site Dose Calculation Manual, NPDES Permit, and continuation of the Callaway Plant Pre-Operational Environmental Monitoring Program.

Samples are collected from waterborne, airborne, ingestion, and direct radiation pathways.

The types of sample media collected are: milk, surface water, ground water, shoreline sediment, bottom sediment, soil, wetlands, fish, vegetation, airborne particulate, airborne radioiodine, and direct radiation (TLD). Indicator samples are collected from locations which could be influenced by plant effluents. Control samples are collected at locations that are not significantly affected by plant operation.

Samples are collected by Union Electric personnel or contractors to Union Electric and shipped to Environmental Inc. - Midwest Laboratory (EIML) and Framatone for analysis.

The data is reported monthly and summarized in the annual report.

2.3 Program Description Sample locations for the REM P are shown in Figures I and 11. Table I identifies the location code, description, and sample type. Table II specifies the collection frequency and required analysis.

Radiological Monitoring Program 2.4 Sampling Program Execution and Results 2.4.1 Program Modifications and Exceptions During 2005, no significant changes were made to the Radiological Environmental Monitoring Program.

The Radiological Environmental Monitoring Program was executed as described in the ODCM with any exceptions listed in this report.

2.4.2 Detection and Reporting Limits Table Ill gives the minimun 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".

Positive sample results are reported with a 2 sigma counting uncertainty (corresponding to the 95% confidence level). Cases where the activity is found to be below the sample analysis minimum detection level are reported as Not Detected (ND).

Radiological Monitoring Program 2.4.3 Quality Control Program The vendor laboratory, Environmental Inc. -

Midwest Laboratory, maintains a quality assessment (QC) program in accordance with Regulatory Guide 4.15. The program includes laboratory procedures designed to prevent cross contamination and to ensure accuracy and precision of analyses. QC checks include blind, duplicate, and spiked samples as necessary to verify laboratory analysis activities are being maintained at a high level of accuracy.

The contractor laboratory participates in the Department of Energy's Environmental Measurements Laboratory QualityAssessment Program (EML), Mixed Analyte Performance Evaluation Program (MAPEP), and Environmental Resource Associates (ERA). The results of these cross check programs are presented in Section 2.6.

The Environmental TLDs are processed by Framatome. This lab meets the required quality control beg maintaining a NVLAP (National Voluntary Laboratory Accreditation Program)

Certification.

compared to established environmental levels produced from weapons testing.

Sample results can also be compared with preoperational levels or samples collected in other parts of the country. Results can also be related to events known to have caused elevated levels of radiation in the environment.

2.4.5 Waterborne Pathway Surface Water Analysis Tritium: A 60-70 ml aliquot of water is purified by distillation. A portion of the distillate is transferred to a counting vial and scintillation fluid added. The contents of the vial are thoroughly mixed and counted in a liquid scintillation counter.

Gamma Spectrometry: Asuitable aliquot of sample is placed in a standard calibrated container and specific nuclides are identified and quantified using a germanium detector coupled to a computer based multichannel analyzer.

2.4.4 Data Interpretations Sample analysis results are evaluated to determine if the result was due to the operation of the Callaway Plant or other sources.

One evaluation method used is the indicator-control concept. Most sample types are collected at both indicator (areas potentially affected by plant operations) and control locations (areas not significantly affected by plant discharge). A possible plant effect would be indicated if the detected level at an indicator location was statistically greater than at the control location.

Another method involves determining if the result originated from weapons testing. The indicator or control sample result can be Sampling and Frequency Monthly composite samples of surface water from the Missouri River are collected from one indicator location (S02) and from one control location (SO1) and shipped to EIML for analysis.

Results The indicator water sampler (S02) was operational 90.7% of the time during 2005.

Sampler operability is verified shiftly (every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months ) by use of a dial up modem. Actions are promptly taken to return the sampler to service when a problem is identified. If the sampler does not collect >250 mIs per day, daily grab samples are collected and composited.

Most of the thirty-three days of indicator water 12

Radiological Monitoring Program Sampling of the Missouri River is accom-plished using an automated compositor.

Samples are collected on an hourly basis and mixed to make the monthly composite sample. River sampling verifies that Callaway Plant discharges meet stringent regulatory requirements.

The control water sampler (SO1) was operational 91.2% of the time in 2005. This sampler is checked weekly. Actions are taken to promptly return the sampler to service when a problem is identified. If the sampler cannot be returned to service within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , daily grab samples are collected. Eight of the thirty-two days of inoperability in April, was due to scheduled power outages, 7 days in June to replace and repairthe sample pump (JOB 05104857), 2 days in September to repair sampler piping (CAR 200506775), and 15 days in October to replace the sample pump and piping (CAR 200508313).

Deviations during 2005 included a grab sample in September that could not be obtained in the pre-designated location due to debris that had accumulated along the shoreline of the Missouri River. The sample was obtained several yards upstream of the normal grab sample location at the steam generator loading dock (CAR 200506775).

Tritium was the only radionuclide detected in surface water samples collected during 2005.

Five of the twelve samples collected at the control location S01 contained measurable levels of tritium with a mean concentration of 332.7 pCi/L.

This is due to tritium recirculation into the intake from the plant outfall CARs 200502277, 200507774, and 200505407.

The gamma analysis results for surface water samples were consistent with previously accumulated data and no plant operational effects were identified.

Drinking I Ground Water Analysis Tritium: A 60-70 ml aliquot of water is purified by distillation. A portion of the distillate is transferred to a counting vial and scintillation fluid added. The contents of the vial are thoroughly mixed and counted in a liquid scintillation counter.

Gamma Spectrometry: A suitable aliquot of prepared sample is placed in a standard calibrated container and specific nuclides are sampler inoperability (S02) were due to the pump or piping iailures.(CARs 200503122, 200504843, 200509665, and 200510134).

Deviations during 2005 included a missed grab sample on December 8th due to snow and ice on the shoreline of the Missouri River when the composite sampler had failed. (CAR 200510055).

Tritium was the only radionuclide detected in surface water samples collected during 2005.

Five of the twelve samples collected at indicator location S02 contained measurable levels of tritium with a mean concentration of 327.6 pCi/L.

The Tritium results from S02 for 2005 were less than 1.5% of the reporting limit in surface water and well within regulatory requirements. Tritium results at S02 are being trended along with monthly liquid H-3 releases and Missouri river flow.

The analysis results are consistent with previous operational levels and there was no significant radiological impact on the health and safety of the public or on the environment.

Radiological Monitoring Program identified and quantified using a germanium detector coupled to a computer based multichannel analyzer. Analysis for 1-131 is accomplished using chemical separation followed by gas flow proportional counting techniques.

Sampling and Frequency Ground water samples are collected quarterly from two sampling (deep) wells (FO5 and F1 5) and two (deep) drinking water wells (D01 and PW1). Four additional shallow wells (GWS/936/

937C/937D) were added to the Callaway REMP due to positive tritium results found in these on site aquifers. The samples were taken as a result of NRC Information Notice 2004-05, Spent Fuel Pool Leakage to Onsite Groundwater at Salem. An exhaustive study of the source of tritium was conducted in 2004 and determined to be from recirculation of liquid effluents (CAR 200403826).

The study indicated that no additional pathways, other than those identified in the Callaway ODCM, were affected.

Bottom Sediment Analysis

- Gamma Spectrometry: A suitable aliquot of prepared sample is placed in a standard calibrated container and specific nuclides are identified and quantified using a germanium detector coupled to a computer based multichannel analyzer.

Sampling and Frequency Bottom sediment samples are collected semiannually from one indicator location (C) and one control location (A). The samples are taken from water at least 2 meters deep to prevent

influence of bank erosion. A Ponar dredge is used to obtain the samples, consisting of the uppermost layer of sediment. Each sample is placed, without preservative, in a plastic bag, sealed and shipped to EIML for analysis.

Results The well samples are collected using an electric pump that is located in the well. The drinking water samples are collected from a faucet after allowing the line to flush for two minutes. The shallow well samples are collected by Engineering Surveys & Services. Samples are shipped to EIML for analysis.

Results Tritium was the only radionuclide detected in the shallow wells collected during 2005. Twelve of the sixteen samples collected contained measurable levels of tritium with a mean concentration of 333.0 pCi/L.

The analysis results for all drinking/ground water samples were consistent with previously accumulated data and no plant operational effects were identified. (Note: groundwater samples are analyzed with the more conservative LLD limits associated with drinking water.)

The analysis results for bottom sediment samples in 2005 were consistent with previously

accumulated data including pre-operation and no plant operational effects were identified.

Shoreline Sediment Analysis Gamma Spectrometry: A suitable aliquot of

prepared sample is placed in a standard calibrated container and specific nuclides are identified and quantified using a germanium detector coupled to a computer based multichannel analyzer.

Sampling and Frequency Shoreline sediment samples are collected semiannually in the same area as bottom sediment. These samples are collected within two feet of the edge of the water and consist of 2 six-

inch diameter by two-inch deep sediment plugs.

Each sample is placed in a plastic bag, sealed and shipped to EIML for analysis.

14

Radiological Monitoring Program Results Cs-137 was the only isotope identified in one of the two samples from the control location (A). The level of Cs-1 37 was consistent with the levels identified during pre-operation of the plant. This was documented in CAR 200507792.

The analysis results for shoreline sediment samples in 2005 were consistent with previously accumulated data including pre-operation and no plant operational effects were identified.

Results Cesium 137 (Cs-i 37) was detected in the Wetlands soil samples. Station (WI) indicated 103 pCi/Kg dry, station (W2) indicated 181 pCi/

Kg dry, station (W3) indicated 139 pCi/Kg dry, and station (W4) indicated 44 pCi/Kg dry.

The analysis results for Wetlands soil samples in 2005 were consistent with previously accumulated data and no plant operational effects were identified. The Cs-I 37 activity is due to world wide fallout from atmospheric nuclear testing.

Shoreline sediment samples are collected two feet from the edge of the water in the same location as the bottom sediment samples. Sediment samples indicate there has been no impact on the environment from 6/

Callaway Plant liquid discharges/effluents.

2.4.6 Airborne Pathway Airborne Analysis Gross Beta: The filters are analyzed approximately five days after collection to allow for decay of natural short-lived radionuclides. Aglass fiber type filter is placed into a stainless steel planchet and counted for gross beta radioactivity using a proportional counter.

Iodine: Each Charcoal cartridge is placed on the germanium detector and counted. A peak of 0.36 MeV is used to calculate the concentration at counting time. The equilibrium concentration at the end of the collection is then calculated. Decay correction for the time interval between sample collection and counting is then made.

Gamma Spectrometry: Filters are composited according to location and counted using a germanium detector coupled to a computer based multichannel analyzer. The resulting spectrum is analyzed by computer and specific nuclides, if present, identified and quantified.

Wetlands Soil Analysis Gamma Spectrometry: Asuitable aliquot of prepared sample is placed in a standard calibrated container and specific nuclides are identified and quantified using a germanium detector coupled to a computer based multichannel analyzer.

Sampling and Frequency Wetlands soil samples are collected annually from 3 indicator locations (W2, W3, and W4) and one control location (Wi). Two 6-inch square soil plugs consisting of the uppermost two-inch layer of soil are taken at each location. The samples are placed in plastic bags, sealed and shipped to EIML for analysis.

.11 Sampling and Frequency Airborne particulate samples are collected on a 47mm diameter glass fiber filter type A/E (99 percent removal efficiency at 1 micron particulate) at a volumetric rate of one and one-half cubic feet per minute.

15

Radiological Monitoring Program Each airborne particulate air sampler is equipped with a charcoal cartridge filter in-line after the particulate filter holder.

The filters are collected weekly and shipped to EIML for analysis.

All five sample locations are considered indicator locations (Al, A7, A8, A9, and B3). One indicator station (A9) is located at the community with the highest D/Q.

Results Air station A7, A9, and B3 were operational 100% of the time in 2005 with the annual sampler calibration change out the only out of service time assigned.

Air station Al was operable 100% of the time in 2005, but was inoperable 0.1 hours1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months in May to replace a defective fitting (CAR200503542). Air station B3 had an hour meterfailure. No out of service time was warranted for B3 due to the run time being calculated based on the power usage of the air station (CAR 200504019).

In September, an overgrown weeping willow tree in the vicinity of air station A7 was found affecting its ability to sample the environs. The area surrounding the air station was cleared as noted in CAR 200506938.

Air Station A8 was operational for 96.0% of the time in 2005. Most of the inoperability is due to hour meter failures or loss of power to the sample pump as documented in CARs 200508165, 200507874, 200507586, 200506015, and 200505830. This sampler is located in an area where it is exposed to a dustier environment than any of the other samplers and this may be a contributing factor to the repeated failures at this location.

A deviation to the sampling occurred for all the air stations for the week of March 24, 2005 to March 30, 2005 when the air samples were lost in shipping to the vendor lab (CAR 200502314). A second deviation is when the samples were sent with a cooling tower blowdown sample on September 29, 2005. The samples were dried by the lab and analyzed. The results of the air samples do not appear to have been impacted due to the samples getting wet in transport (CAR 200506304).

Gross beta activity sample results ranged from 0.005 to 0.052 pCi/M3. The average gross beta activity for all sample locations was 0.024 pCi/m3.

In 2005, there were 16 weekly samples with gross beta activities greater then the base line action level of 0.037 pCi/M3. Gamma spectral analysis was performed on these filters and no gamma emitting isotopes of plant origin were detected.

The analysis results for airborne samples are consistent with previously accumulated data and no plant operational effects were identified.

Airborne samples are continuously col-lected. Particulates are gathered on a glass fiber filter. A charcoal filter is in line after the particulate filter to collect iodines. Air samples indicate the Callaway Plant has had no impact on the surrounding environment 16

Radiological Monitoring Program 2.4.7 Ingestion Pathway Milk Analysis Iodine-1 31: Two liters of milk containing standar(G.ed Iodine carrier is stirred with anion exchange resin for one hour. The resin is washed with NaCI and the iodine is eluted with sodium Hypochlorite. Iodine in the iodate form is reduced to 12 and the elemental iodine extracted into CCI4, back-extracted into water, then precipitated as palladium iodide. The precipitate is counted for 1-131 using a proportional counter.

Gamma Spectrometry: An aliquot of milk is placed in a standard counting container and specific nuclides are identified and quantified using a germanium detector coupled to a computer based multichannel analyzer. Analysis for 1-131 is accomplished using chemical separation followed by gas proportional counting techniques.

When available, one-gallon milk samples are collected semimonthly during the grazing season (typically April through September) and monthly during the winter from two indicator stations near the Plant (M6 and Ml 3) and one control location away from the Plant (M8). Milk samples have sodium bisulfite added as a preservative, and are shipped on ice to EIML for analysis within eight days after collection.

Results Milk samples were unavailable due to animals not producing milk during the following periods:

Location M13:

Milk samples were unavailable 1/11,2/6, 4/12,4/26, 5/10, 5/24,6/14, 6/28,7/12, and 12/12 (CARs 200503066, 200500059, and 200501269).

Location M8 & M6:

All samples were collected as scheduled.

Samples were collected monthly in January, February, March, and December (stored feed). Samples were collected semimonthly for all other months since the milking animal was spending a portion of it's time grazing.

The analysis results for milk samples were consistent with previously accumulated data and no plant operational effects were identified.

Fish Analysis Gamma Spectrometry: A prepared sample is placed in a standard calibrated container and specific nuclides are identified and quantified using a germanium detector coupled to a computer based multichannel analyzer.

Sampling and Frequency The five most abundant recreational or commercial fish species are collected semiannually from one indicator location (C) and one control location (A). After collection, fish samples are shipped on ice to EIML analysis.

Sampling and Frequency Fish are collected by Union Electric biolo-gists. Fish samples indicate there has been no impact on the environment due to opera-tion of the Callaway Plant.

Radiological Monitoring Program Results The analysis results for fish samples were v

consistent with previously accumulated data and no plant operational effects were identified.

Vegetation Analysis lodine-l :31: Asuitable aliquot of wet (as received) sample is placed into a standard calibrated container and counted using a germanium detector coupled to a computer based, multichannel analyzer. A peak of 0.36 MeV is used to calculate the concentration at counting time. The equilibrium concentration at the end of collection is calculated by decay correcting for the time interval between sample collection and counting.

Gamma Spectrometry: A suitable aliquot of wet (as received) sample is placed into a standard calibrated container and specific nuclides are identified and quantified using a germanium detector coupled to a computer based multichannel analyzer.

Sampling and Frequency Monthly during the growing season, green leafy vegetation is collected from four indicator locations V9, VI 0, VI1, and VI 3 and from one control location VI 2. Vegetation samples consisted of mustard greens, turnip greens, cabbage, lettuce, collards, radish greens, swiss chard, broccoli, and poke. Other broad leaf vegetation is requested and/or collected if primary varieties are not available. Samples are shipped to EIML for analysis.

Results Vegetation samples were collected as available from May through December due to unseasonably milder temperatures in November and December. The following indicates the months where no vegetation samples were collected:

Location V9:

June through November.

Location Vi 0:

May through July, and September through November.

Location VI 1:

May through December Location V1 2:

May through October Location VI 3:

May, June, and August The analysis results for vegetation samples were consistent with previously accumulated data and no plant operational effects were identified.

2.4.8 Direct Radiation Exposure Pathway Direct Radiation Analysis The Union Electric program uses the Panasonic Model UD-814 TLD dosimeter. Each dosimeter consists of three elements of CaSO4:Tm. The dosimeters are sealed in a water proof plastic bag and placed inside a polypropylene mesh cylindrical holder in the environment. After exposure in the environment the dosimeters are read and the result is adjusted to a standard quarter of 90 days.

Sampling and Frequency Thermoluminescent Dosimetry (TLD) is used to determine direct radiation levels in and around the Callaway site. Forty-three dosimeters are placed in 16 sectors around the plant as specified in the ODCM. The dosimeters are read once per quarter. Three locations are designated as controls (IDM26, IDM27 and IDM60).

18

Radiological Monitoring Program Results Direct radiation data for IDM- 0 was unavailable in the second quarter, apparently due to vandalism (CAR 200503541). The fourth quarter IDM-5 sample was lost during processing by the vendor.

The analysis results for TLD samples were consistent with previously accumulated data and no plant rperational effects were identified.

2.4.9 Other Exposure Pathways Soil Analysis Gamma Spectrometry: A suitable aliquot of prepared sample is placed in a standard calibrated container and specific nuclides are identified and quantified using a germanium detector coupled to a computer based, multichannel analyzer.

Sampling and Frequency Soil samples are collected annually from four indicator locations (F2, PR3, F6, and PR7) and one control location (V3). To ensure only the most recent deposition is sampled, the uppermost two-inch layer of soil is taken at each location. Samples consist of 2 six-inch square soil plugs; The litter at the surface and the root mat is considered part of the sample. The samples are placed in plastic bags, sealed and shipped to EIML foranalyses.

Pictured is one of the forty three dosim-eter locations used to measure direct radia-tion. Direct radiation data indicates there has been no impact from the operation of the Callaway Plant.

The analysis results for soil samples in 2005 were consistent with previously accumulated data including pre-operation and no plant operational effects were identified. The Cs-I 37 activity is due to worldwide fallout from atmospheric nuclear testing.

The analysis results for soil samples were consistent with previously accumulated data. Soil sampling is a continuation of the preoperational environmental monitoring program.

Results Cesium 137 (Cs-137) was detected at control station V3 at 308 pCi/Kg dry, while the highest indicator station result was 873 pCi/L dry.

19

Radiological Monitoring Program REMP Supplemental Samples Several supplemental samples were taken during 2005 which were not required by FSAR-SP Table 16.11-7. A corn sample was collected from a field within the site bourndary to further assess the impadt of plant operation on the environment.

The corn field within the site boundary was harvested for commercial purposes. Sample results are listed in Table XVI.

Vegetation samples were also taken during the growing season in areas of the field near and away from the pipe break to assess the impact on the vegetation in the area. The results are also reported in table XVI.

The samples were sent to EIML for analysis.

The results listed in Table XVI are consistent with previously accumulated data and no plant operational effects were identified.

In January 2005, it was identified that the plant discharge line had ruptured in a field near the Missouri river where a cement crossing was created to facilitate bringing Callaway's replacement steam generators and low pressure turbines from the river (CAR 200500214). Soil and water samples were taken from the area and the results are documented in Table XVI.

Radiological Monitoring Program 2.5 Land Use Census The Land Use Census is performed annually during the growing season within a five-mile radius of the Callaway Plant. The location of the nearest resident, milking animal, and garden greater than 50 m2 (500 ft2) is identified by contacting residents by phone and/or in field surveys for each of the sixteen meteorological sectors using the midpoint of the two units.

The Union Electric Real Estate Department conducted the 2005 Land Use Census the last two days of August and the first day of September.

Results The results of the 2005 Land Use Census are presented in Table IV. The table includes radial direction and distance from the Callaway Plant for each location. These parameters were determined using a combination of map position, aerial photography, and a Global Positioning System (GPS) receiver.

Nearest Resident The distance of the nearest resident with the highest DIQ was unchanged for 2005. This resident lives 1.82 miles from the plant in the NNW sector. New construction was observed during the field inspection; however, none qualified as closest resident in any of the sectors.

Milking Animals No new residents with milking animals were located in any of the sectors.

Comparison of the current REMP milk sample participants with residents identified as having milking animals in the 2005 Land Use Census indicates that no changes are necessary.

Vegetable Gardens No new residents with vegetable gardens were determined to have a 20% higher average ground level D/Q than current REMP sample participants.

Therefore, no changes to the REMP vegetable garden sampling are necessary.

3The orignal samples were calculated using an Am-241 efficiency. The samples were spiked with Th-232.

Samplese were recounted and calculated using the Th-232 efficiency. Tesults of the recount: 27.01 +/- 2.35 pCi/L.

4 Decay of short-lived radium daughters contributed to a higher counting rate. Delay of counting for 100 minutes provided better results. The reported result was the average of the first cycle of 100 minutes, the average of the second cycle counts was 4.01 pCi/L.

Radiological Monitoring Program 2.7 Data Reporting Conventions Lower Limit of Detection The lower limit of detection (LLD) used in this report is per NRC Regulatory Guide 4. 1, Rev. 1, "Program for Monitoring Radioactivity in the Environs of Nuclear Power Plants", and the NRC Branch Technical Position, November 1979, "An Acceptable Radiological Environmental Monitoring Program". The LLD is defined as the smallest concentration of radioactivity material in a sample that will yield a net count (above system background) that will be detected with 95%

probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.

The maximum LLDs for radiological environmental sample analysis is presented in Table ll.

Data Reporting Positive sample results are reported with a 2 sigma counting uncertainty (corresponding to the 95% confidence level). In cases where the activity is found to be below the sample analysis minimum, the activity is reported as Not Detected (ND).

2.8 Radiological Environmental Monitoring Program Annual Summary.

The REMP Summary is presented in Table VI in accordance with NRC Regulatory Guide 4.1, Rev. 1, "Program for Monitoring Radioactivity in the Environs of Nuclear Power Plants", and the NRC Branch Technical Position, November 1979, "An Acceptable Radiological Environmental Monitoring Program". In cases where the activity is found to be below the sample analysis minimum, the activity is reported as < LLD.

With the exception of a small indication of tritium in riverwater, there was no measurable impact on the environment due to plant operation.

This section lists all changes in the plant design, operation, tests or experiments installed during 2005, which could have involved a potentially significant unreviewed environmental question in accordance with section 3.1 of Appendix B.

During 2005, there was one plant design and one operation activity 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 are presented below.

Callaway Discharge Line Break Description of Activity:

On January 11, 2005 Steam Generator Replacement Project (SGRP) Contractor identified a hole in the ground with water bubbling up nearthe new concrete crossing installed plant east of the Intake Structure Access Road.

AmerenUE Engineering personnel went to investigate later that day and noted there was a hole but no water bubbling or movement. After checking with Radwaste Department, it was discovered that blowdown flow was raised from around 2700 gpm to 5700 gpm from 0200 until 1000 for Discharge Monitor Tank (DMT) discharge activity. A planned increase in blowdown flow was subsequently performed on January 12 at 1000.

Personnel were in position prior to the blowdown flow increase and again noted no water level in crease or bubbling within the hole. After approximately 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months , bubbling and some minor water flow within the hole was identified. This indicated that the 24" diameter discharge line was leaking somewhere in the vicinity of the new concrete crossing installed to support the SGRP transportation activities at certain flow rates.

The amount of the leak was believed to correspond to Missouri River level since the river level was above the pipe discharge elevation, thereby causing a slight backpressure on the discharge line. The river elevation on 1/11 was around 513' and 1/12 was around 510'. It was a high 526' within the last couple of weeks.

3.0 Non-Radiological Monitoring Program With lower river levels and under normal plant blowdown conditions (approx. 2700 gpm), there were no indications of leakage. Repair of the piping was completed on January 21, 2005 when the weather and soil conditions permitted excavation and access for equipment and personnel.

Evaluation of Activity:

The continued use of the discharge line in its degraded condition until repairs can be completed was evaluated. As noted in the description, there are no conditions of lower river level and low discharge flow that resulted in not visible indications of discharge line leakage. A Missouri River level of 511 feet or less at the Callaway Plant intake structure combined with limiting the cooling tower blowdown discharge and bypass flow to 2700 gallons per minute or less resulted in no surface indications of discharge line leakage.

The leakage from the discharge line is located approximately 400 yards upstream from the discharge point to the Missouri River. The site is located south of highway 94 in the Missouri River Flood plain. The discharge line is buried 10 to 12 feet deep in the area of the break. In this area the subsurface water is hydraulically connected to the Missouri River.

Discharge from the cooling tower blowdown and bypass are the highest volume outfalls that are discharged from the discharge line. These outfalls have no radioactive component and are regulated by the Missouri Department of Natural Resources (MDNR). The MDNR has been advised of the degraded condition of the discharge line and that conditions are such that the line repairs can not be initiated until river level decreases. It was acceptable to continue discharge from the cooling tower as long as flow is limited to 2700 gpm even if river level is greater than 511 feel at the Callaway Intake.

Discharge from the Radwaste Treatment System is also regulated by the MDNR for non radiological components, but it also has a radioactive component that is regulated by the N RC. The system is such that after the radwaste system discharge has mixed with the water from the cooling tower blowdown or bypass, it will meet the 10 CFR 20 limits. This mixing would be complete long before it reaches the location of the discharge line that is degraded. If the flow from the cooling tower is limited to 2700 gpm and the river level is at or below 511 feet at the Callaway intake, it is acceptable to discharge from the radwaste treatment system. This was with current conditions of the discharge line and no surface indications of a leak. While discharging from the radwaste system the surface indications should be checked periodically for leakage indications.

All chemical and radiological releases will be within the established limits for the plant. In addition, the compensatory actions imposed will minimize any adverse environmental impact that would be expected from this deviation from our discharge location.

This activity did not significantly affect the concentrations, frequencies or types of effluent being discharged from the plant, and does not affect the current plant power level. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

3.0 Non-Radiological Monitoring Program Callaway Modification 02-2002:

Description of Modification:

This modification allowed the installation of approximately 8567 feet of 3 inch Class 200 PVC piping to provide potable water to the new Callaway Plant Gun Range Facility. This piping is an extension from the existing potable water system (tie in Plant South of the power block near the circ/service water pump house) to the new facility. It was estimated that approximately 0.4 acres of land will be disturbed to install this piping in a trench with a maximum width of 2 feet and a depth of 48 inches. Since this modification does involve a drinking water supply, permitting is required by the State of Missouri Department of Natural Resources prior to beginning any construction.

Evaluation of Change:

Both the ER and FES-OL were reviewed against Modification 04-9030 Revision C for any previously evaluated adverse environmental impacts and any adverse environmental impacts not previously evaluated. No adverse environmental impacts were identified. The installation of this potable water piping described above has no effect upon effluents or power level.

Some'excavation will be required to install the new section of potable water piping. It is estimated that approximately 0.4 acres will be disturbed to install this 3 inch PVC piping. The routing of this new pipe was reviewed against "A Cultural Resources Management Plan for Residual Lands at the Union Electric Company Nuclear Power Plant, Callaway County, Missouri."

Although land will be disturbed outside of the Callaway Plant owner controlled area, no identified cultural resources will be affected by the installation of this piping.

The entire area to be excavated is estimated to be less than one half acres and will not adversely effect stormwater runoff. Because of the total area to be disturbed is less than one half acre, no stormwater permit is required. However, any material excavated to install this piping will be contained or removed to prevent discharge to stormwater. Installation of most of the new potable water piping will be in locations where any rainfall that could result in stormwater runoff being discharged through a point source to the waters of the state, will be discharged through Outfall 010 and Outfall 011. These Callaway Plant Stormwater Outfalls are currently permitted by the State of Missouri.

Installation of this potable water piping will not result in a new, different or increased discharge of pollutants that could affect the NPDES Permit.

This modification to install the potable water piping does not create an oil waste stream that could be released to the environment. Petroleum use by facility construction equipment is controlled and contained to accepted equipment standards.

This modification will not significantly affect the concentrations, frequencies or types of effluent being discharged from the plant, and does not affect the current plant power level. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License. Construction of the OSGSF will require excavation of the structure's foundation, and these activities will be controlled by means appropriate to limit any potential soil erosion. The areas surrounding the facility will be surface stabilized as part of this modification. Grading of the area of the OSGSF construction will route rainfall to an acceptable water runoff pattern to account for the effects of local intense precipitation described in Section 2.4.2.3 of the Site FSARAddendum. The stormwater runoff will ultimately be discharged through outfall 014 which is a stormwater outfall in our NPDES permit. The actions taken to minimize soil erosion along with the retention pond for this outfall will maintain all limited parameters within our NPDES limits.

This modification will not significantly affect the concentrations, frequencies or types of effluent being discharged from the plant, and does not affect the current plant power level. Therefore, this change does not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

v, 3.0 Non-Radiological Monitoring Program Callaway Modification 02-1010 Evaluation of Change:

Description of Change:

This change is to permanently expand the protected area security boundary to encompass the area outside security fence on the eastern v

most (oriented to Plant North) side of the existing site protected area (PA) boundary to the portion of the Unit 2 excavation that has been backfilled in.

Under separate modification packages, various SGR support facilities, both temporary and permanent, are being erected in this backfilled area as well. Modification Package 02-1010 confines its scope to the ensuring that the permanent extension of the PA security boundary meets all required regulations, codes, and standards for design, construction, and operation of security/safeguards features for the Callaway Nuclear Plant. In summary, Modification Package 02-1 010 will:

1. Prepare the ground surfaces of the designated new PAsecurity boundary and permanently erect the required double security fences and install other necessary security boundary physical hardware. This includes required physical isolation of gratings/openings/culverts within the zone between the inner and outer new security boundary fences.

2. Provide appropriate access points to the extended PA security boundary area.

3. Permanently install required area lighting and monitoring/detection/alarm systems.

4. Provide for covering and surface stabilization of the new PA security boundary areas adjacent and within the inner and outer security boundary fences for acceptable water runoff, as well as for functionality of detection systems.

5. Perform functional qualification of the detection and alarm systems so that proper transition to the new permanent PA security boundary and coordinated removal of the pre-modification (defunct) security boundary fences may be accomplished.

The construction activities to extend the PA security boundary undertaken by Modification Package 02-101 0 will be performed in a site area that has been previously evaluated and determined to not be associated with cultural resources identified in "A Cultural Resources Management Plan for Residual Lands at the Union Electric Company Nuclear Power Plant, Callaway County, Missouri."
