2.0 Radiological Monitoring Program 2.1 Introduction This report presents an analysis of the results of the REMP conducted during 2003 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 River flows by the site in an easterly direction approximately five miles south of the site at its closest point.

Samples are collected by Union Electric personnel or contractors to Union Electric and shipped to Environmental Inc. - MidWest Laboratory for analysis. The data is reported monthly and summarized in the annual report.

TLD's are analyzed by Union Electric personnel.

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

2.2 Program Design The sample locations, frequency of sampling, and sample analysis requirements originate from the Callaway Plant OffSite 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.

Radiological Monitoring Program 2.4 Sampling Program Execution and Results 2.4.1 Program Modifications and Exceptions During 2003, 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 Aerial view of the Callaway Plant site.

Limits Included is some of the land worked by local farmers to produce feed for cattle.

Table IlIl gives the 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).

Note: In 2003, Callaway began adding depleted Zinc to the reactor coolant system to reduce radiation exposure. As a result, FSAR I Tables 16.11-8/9 were revised to add detection and reporting levels for Zinc-65 as per the NRC Branch Technical Position, Rev. 1, November 1979.

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

Midwest Laboratory) maintains a quality control (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 Callaway Plant Personnel Dosimetry program is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) of the National Institute of Standards and Technology (NIST). The Environmental TLD Program has demonstrated compliance with the recommendations of Regulatory Guide 4.13.

Quality control checks are performed including blanks, blind samples, daily performance checks, and quarterly crosschecks.

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 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.

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 (S01) and shipped to Environmental Inc.

-Midwest Laboratory for analysis.

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 Cal/away Plant discharges meet stringent regulatory requirements.

drawings (CAR 200308728), sample proportioning (D-Y) valve leakage/oscillations (CARs 200305922/200308246), and pump failures (CAR 200304608/200308728). These conditions were repaired and/or corrected and the sampler was returned to service. Other conditions such as frozen sample lines, electric power outages, and low river water levels also contributed to sampler inoperability. Operability concerns with indicator water sampler S02 were also tracked in CARs 200303422/200300874/

200302227.

Deviations during 2003 included missed grab samples on 1/23 and 1/24. These samples were not taken due to snow and ice on the shoreline of the Missouri River (CAR 200300871). The indicator water sampler S02 was also inadvertantly secured on 3/11 and 3/12 during maintenance activities (CAR 200302227). Grab samples were collected from the Missouri River on both days. On 11/14/03, a indicator water station grab sample was miscomposited as per HTP-ZZ-07001 (CAR 200308265). This combined with excessive sampling during the week from faulty sample proportioning valve operation (CAR 200308246) caused the indicator water sample for the period to become disproportionate. As a compensatory measure, the composite sample collected from 11/10 - 11/19 was sent to Environmental Inc. - Midwest Laboratory for analysis. The remaining portion of the monthly sample (11 /19 - 12/9) was collected and shipped as normal. The contract lab analyzed each sample and then composited the two samples and reanalyzed. The reported value for S02 in Table Xi is the combination of the two samples.

The control water sampler (S01) was operational 98% of the time during 2003. This sampler is checked weekly. Immediate action is taken to return the sampler back to service when a problem is identified. If the sampler cannot be returned to service within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, daily grab Results The indicator water sampler (S02) was operational 92% of the time during 2003.

Sampler operability is verified shiftly (every 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />) by use of a dial up modem. Immediate actions are 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.

Sixteen of the thirty days of indicator water sampler inoperability (S02) were due to pump controller failure in January and February.

Obsolete pump controller parts contributed to and/

or extended the out of service time as described in CAR 200300874. Additional operational problems with the indicator water sampler (S02) included issues encountered during scheduled maintenance, inadequate pump rebuild instructions (CAR 200305727), inadequate 13

Radiological Monitoring Program samples are collected. Exceptions during 2003 included 5 days of inoperability in November, due to timer failure. As a result of timer failure, grab samples were missed on 11/24 and 11/25. The missed grab samples were due to miscommuncation between Operations and Health Physics (CAR 200308622). To help eliminate this problem a scale similar to the one at indicator sampler S02 was placed under the sample bottle. Operations procedure OOA-RM-0002 was also revised and the groups were coached and trained on the new requirements.

The control sampler was also inoperable for 1 day in October due to a scheduled power outage.

Tritium was the only radionuclide detected in surface water samples collected during 2003.

Five of twelve samples collected at indicator location S02 contained measurable levels of tritium with a mean concentration of 404.2 pCi/L.

The Tritium results at S02 are 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 2003 results are consistent with previous operational levels and there was no significant radiological impact on the health and safety of the public or the environment.

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

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 wells (F05 and F1 5) and two drinking water wells (DO1 and PW1).

The well samples are collected using an electric pump that is located in the well. The drinking water sample is collected from a faucet after allowing the line to flush for two minutes. Samples are shipped to Environmental Inc. - Midwest Laboratory for analysis.

Results The analysis results for all ground water samples were consistent with previously accumulated data and no plant operational effects were identified.

Results Cesium 137 (Cs-i 37) was detected in the Wetlands soil samples. Station (Wi) indicated 147 pCi/Kg dry and Station (W2) indicated 161 pCi/Kg dry.

The analysis results for Wetlands soil samples in 2003 were consistent with previously accumulated data and no plant operational effects were identified. The Cs-i 37 activity is due to worldwide fallout from atmospheric nuclear testing.

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. A glass 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 calculated 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 I multichannel analyzer. The resulting spectrum is analyzed by computer and specific nuclides, if present, identified and quantified.

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

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 Environmental Inc. - Midwest Laboratory 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.

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.

Radiological Monitoring Program Results Air station A-1 was operational 99.7% of the time in 2003. Problems with the flow meter on the air sample skids in Jan and Dec was the cause(CAR 200400018). To correct this problem, Callaway is in the process of systematically replacing these flowmeters.

Air station A-7 was operational for 99.9% of the time in 2003. Timer failure in May caused the air sampler to be out of service 30 minutes for sampler replacement after it was determined the air sampler was operable by electric meter reading. Also, during the first weekly filter changeout in April, the flowmeter was reading high as per Health Physics procedure. The air sample skid was replaced and 6.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> of inoperability assigned to air station A-7 for the changeout.

However, since the air flow was higher than normal, the air sampler essentially collected a higher sample volume and therefore operability was not affected. The filters were sent to Environmental Inc. - Midwest labs for analysis and assigned a conservative flow rate.

Air station A-8, was operational 98% of the time during 2003. During the week of 6/12/03, the timer on the pump skid was reading approximately 17 hours1.967593e-4 days <br />0.00472 hours <br />2.810847e-5 weeks <br />6.4685e-6 months <br /> low for the week (CAR 200304875).

Thunderstoms during the week caused the air station to become teporarily inoperable. As a result, 168.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> of inoperability was conservatively assigned to air station A-8. The air samples were sent to Environmental Inc. - Midwest labs for analysis.

On 9/12/03, the air sampler on/off switch failed during sample changeout. The airsamplerwas replaced and 2.2 hrs of inoperability were assigned (CAR 20036756).

Air station A-9 was operational 98% of the time during 2003. During the week of 8/7/03, electrical problems caused the sampler to shutdown (CAR 200305713). As a result, 168.4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of inoperability were conservatively assigned to air station A-9. The pump skid was replaced and the filters were sent to Environmental Inc. - Midwest Laboratory for analysis.

Air station B-3 was operational 98% of the time in 2003. On 3/27/03, air sample line integrity was found to be unsatisfactory. The pump skid was replaced and the filter was sent to the vendor lab for analysis and operation of air station was resumed. As a result, 168 hours0.00194 days <br />0.0467 hours <br />2.777778e-4 weeks <br />6.3924e-5 months <br /> of inoperability was assigned to air station B-3.

Gross beta activity ranged from 0.009 to 0.041 pCi/m3 in all samples. The average gross beta activity at all locations was 0.023 pCi/M3. In 2003, there were 13 weekly samples with gross beta activities greaterthen the baseline 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.

2.4.7 Ingestion Pathway Milk Analysis lodine-1 31: Two liters of milk containing standardized 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.

Radiological Monitoring Program Sampling and Frequency 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 are shipped on ice to Environmental Inc. -Midwest Laboratory for analysis within eight days after collection.

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

Location M13:

Samples were unavailable on 1/14,2/11,3/

11, and 4/8 due to inadequate milk production (CAR 200304219). No sample was collected on 5/27 due to miscommunication with the resident (CAR 200304219).

Samples were unavailable on 11/10,11/24, 12/9, and 12/22 due to gestation (CAR 20040978).

Location M8:

Samples were unavailable due to problems encountered during the gestation period for the milking animal. Samples were not collected on 8/12, 8/26, 9/9, 9/23,10/13, 10/

28, and 11/10.

The residents of sample location M8 replaced the milking animal and samples resumed 11/

24 (CAR 200307567).

Location M6:

Samples were collected as scheduled.

Samples were collected semimonthly in December, since the milking animal was spending a portion of it's time at pasture.

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). On 1/22/03, the Missouri Dept. of Conservation issued a revised permit that allowed Union Electric to resume collecting channel catfish samples for 2003. After collection, Fish samples are shipped on ice to Environmental Inc. - Midwest Laboratory for analysis.

Fish are collected byAmeren UE 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 consistent with previously accumulated data and no plant operational effects were identified.

Vegetation Analysis Iodine-i 31: A suitable 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.

lack of plant growth, drought conditions, and consumption by deer in 2003. The following indicates the months where no vegetation samples were collected:

Location V9:

January through April, August and September.

Location V1 0:

January through April, and September.

Location Vi1:

January through May, and December Location V1 2:

January through April, and December The analysis results for vegetation samples were consistent with previously accumulated data and no plant operational effects were identified.

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 three indicator locations V9, V1 0, and V11 and from one control location V1 2. Vegetation samples consist of mustard greens, turnip greens, cabbage, lettuce, and spinach. Other broad leaf vegetation is requested and/or collected if primary varieties are not available. Samples are shipped to Environmental Inc. -Midwest Laboratory for analysis.

Results Vegetation samples were collected as available from May through December due to unseasonably milder temperatures in November and December.

Green leafy vegetation was unavailable due to Direct Radiation Analysis The Union Electric program uses the Panasonic Model UD-814TLD and Model UD-710A automatic dosimeter reader. 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 (IDM-26, IDM-27 and IDM-60).

IVJ

Radiological Monitoring Program Results Direct radiation data for I DM-34 and I DM-39 was unavailable in the second and fourth quarter respectively. The apparent cause was due to the replacement of power poles (CAR 200305046).

The TLDs at sample stations 34 and 39 were promptly replaced.

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

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.

i 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 Environmental Inc. -Midwest Laboratoryfor effects were identified. The Cs-137 activity is due to worldwide fallout from atmospheric nuclear testing.

REMP Supplemental Samples Several samples were taken during 2003 which were not required by FSAR Table 16.11-7.

On 5/27/03, a local landowner requested that samples from their vegetable garden be analyzed (CAR 200304121).

In addition, samples of venison, beef, and corn leaves were also taken to further assess the impact of plant operation on the environment.

The beef and corn samples were taken from an animal that grazes in and feeds on corn grown within the site boundary.

The samples were sent to Environmental Inc.

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

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 square meters 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. This is contrary to FSAR 16.11.5.1 which requires using the centerline of one reactor. However, HTP-Z7-071 01 notes that the midpoint of the two units will be used as per FSAR 2.1.1.1. CAR 200402426 was generated to address the issue.

The AmerenUE Real Estate Department conducted the 2003 Land Use Census in September, a month earlier than in 2002, for improved garden indentification.

Results The results of the 2003 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 Global Positioning System (GPS) receiver.

Nearest Resident The distance of the nearest resident with the highest D/Q was unchanged for 2003. This resident lives 1.82 miles from the plant in the NNW sector.

Milking Animals Milking animals identified in sector L (SW) and M (WSW) during the 2002 Land Use Census are no longer present. A resident in sector N (W) was identified as having milking animals. However, the resident is outside of 3 miles from the plant and does not meet the requirements of FSAR Table 16.11-7 (Sheet 3) for sample collection.

In sectorA (N), a resident indicated that he temporarily had milking goats in 2003. The goats were removed due to sewage contamination on his property. The resident indicates that he may have goats in the future if he is able to find available space to relocate them.

Comparison of the current REMP milk sample participants with residents identified as having milking animals in the 2003 Land Use Census indicates that no changes are necessary.

Vegetable Gardens As was the case in 2002, a residence in sector R (NNW) with a vegetable garden was determined to have a 20% higher average ground level D/Q than current REMP sample participants.

The Union Electric Real Estate Dept. made several attempts to request their participation in the Callaway REMP. However, after several calls and letters, it was determined that the resident was not interested (CAR 200308034).

Radiological Monitoring Program 2.7 Data Reporting Conventions 2.8 Radiological Environmental Monitoring Program Annual Summary 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 Ill.

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).

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 river water, there was no measurable impact on the environment due to plant operation.

Non-Radiological Monitoring Program 3.0 3.1 Introduction Union Electric Company 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 2003.

operation changes 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 Request for Resolution 22046 Revi-sion A Description of Change:

3.2 Unusual or Important Events No unusual or important events reportable under the EPP Section 4.1 were identified during 2003.

!3.3 EPP Noncompliances During 2003 there were no noncompliances with the EPP.

3.4 Nonroutine Reports There were no nonroutine reports submitted in accordance with the EPP.

3.5 Plant Design and Operation Environmental Evaluations.

This section lists all changes in the plant design, Woperation, tests or experiments completed during

.2003, which could have involved a potentially significant unreviewed environmental question in accordance with section 3.1 of Appendix B.

During 2003, there were five plant design and This change is to allow the addition of depleted or natural soluble zinc to the Callaway primary system to reduce radiation fields in out-of-core piping and components. Industry experience has shown that even low concentrations of zinc (5ppb) have reduced reactor coolant system (RCS) dose rates by 10-25% per cycle for the cycle zinc is added. The maximum average RCS zinc concen-tration allowed by this evaluation is 40 ppb.

Evaluation of Change:

During this first cycle of injection much of the zinc will be incorporated into the system oxide films.

Some of the zinc added will also be removed by the CVCS mixed bed deminerlizers. Some met-als such as cobalt and nickel in the oxide films that are displaced by the zinc may increase slightly in the RCS. The expected chemical concentration change of the displaced metals is expected to be insignificant. Small amounts of the zinc and dis-placed metals will also be present in primary system waste streams and will be treated by the liquid radwaste system prior to discharge to the Missouri River via Outfall 001, Radwaste system discharge.

It is expected that the treatment systems will remove the majority of the zinc. Industry experience has also shown that the total liquid release of radioactive material for several plants 49

3.0 Non-Radiological Monitoring Program has not increased above their normal liquid effluent releases prior to the addition of zinc. This provides an indication that the chemical concentration of these metals in any wastewater will also be similar to levels present before zinc addition.

The most recent Callaway Plant NPDES Permit i Renewal Application dated October 26,2000, I indicated a total maximum daily zinc concentration in Outfall 001 of 22.1 ppb. Up to five times this reported concentration is allowed without notification to the Missouri Department of Natural Resources (MDNR). Water Quality Standard 10 CSR 20-7 limits zinc in drinking water to 5000 ppb and limits zinc to 103 ppb (worse case - lakes, with a higher limit for the Missouri River) for protection of aquatic life. Assuming an average RCS concentration of 40 ppb zinc, the concentration of zinc expected in Outfall 001 even assuming no treatment of primary liquid waste, should not increase significantly from the levels previously reported prior to zinc addition.

The modificaiton 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.

Callaway Modification MP 03-2003 Description of Change:

This modification constructs a permanent IReplacement Steam Generator (RSG) Storage

• Facility to both store the RSGs and permit onsite preparations of the RSG components to be performed in a facility protected from adverse environmental conditions. To achieve these objectives, the facility itself will have the character of a permanent warehouse erected over a concrete slab.

The RSG Storage Facility has technical requirements to ensure it's present and future uses will be appropriately designed for, including factors suchas building size, capabilities for off/on loading the RSGs and performing RSG component preparations, and functionality for materials handling and storage. The RSG Storage FAcility as constructed under this modificaion does not include tie-ins from potable water or sewage treatment, but rather has rough-in connection points embedded within the facility concrete slab for these two services for potential future use. Such future use would involve routing servicing lines to the facility, connecting them to their associated exterior rough-in penetrations to the facility, and installing servicing equipment within the facility itself.

Evaluation of Change:

Construction of the RSG Storage Facility 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 RSG Storage Facility 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 Site FSAR Addendum. Stormwater discharge from the area where RSG Storage facility is being built ultimately discharges through a permitted outfall in Callaway Plant's NPDES permit. As such, no stormwater permit is necessary for this activity.

50

3.0 Non-Radiological Monitoring Program Evaluation of Change - Callaway Modification 03-2003 (continued):

Evaluation of Change:

The RSG storage facility construction area is on a location that has been previously disturbed during construction and as such will not affect any cultural resources at the site. Since the building will not initially be connected to the sewage treatment system, it will not add any additional load to the sewage treatment system. If it is connected in the future, the increased load should be minor as it will be balanced out from decreased load from other buildings.

This modification will not significantly affect the concentrations, frequencies or types of efluent 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.

Callaway Modification MP 01-1001 Description of Change:

This modification allows the installation and use of Duratek -Advanced Liquid Processing System, (ALPS), equipment for the processing of liquid radioactive waste. Equipment will be installed to allow treatement options of ion exchange and/or filtration with the intent to maximize the activity removal from liquid while minimizing the generation of solid waste.

This modification will also change the vents on the Secondary Liquid Waste (SLW) Monitor Tanks.

The vents will be changed so that the vapors from the tanks will be directed to the Radwaste Building Exhaust ductwork instead of the Radwaste Building.

The vent path for the SLW Monitor tanks is being changed. They currently discharge to the Radwast e Building. After the modification, they will discharge to the Radwaste Building Exhaust ductwork. This modification means that the gaseous vent from the tank will no longer mix with Radwaste Building air prior to the release. This modification means that the gaseous vent from the tank will no longer mix with Radwaste Building air prior to release. The change in the vent path will not result in any net change in gaseous releases or gaseous release points.

The new treatment system will not have any significant environmental impact that hasnot been previously evaluated. Releases of liquid effluents were evaluated in the Final Environmental Statement -Operating License (FES-OL) and the Environmental Report (ER) assuming evaporation, demineralization or filtration treatment prior to discharge. The results from the use of a similar treatment system supplied by a different vendor has shown that deminerlization and filtration can provide adequate treatment to remove pollutants and radioactive isotopes prior to discharge and still meet all limitations on those discharges. Using demineralization and filtration to treat liquid radwaste as per this modification will not create any new or different environmental impact that would be significantly different from those already evaluated in the FES-OL or ER.

An additional treatment chemical, a polyamine coagulent as a filter aid may be used. Some of this chemical will attach to particles and be removed, but some may be discharged from outfall 001. This use of this type of chemical was already described in our last permit reapplication that was submitted to the Missouri Department of Natural Resources in October, 2000.

Additionally, the boron concentration may increase some with deminerlization and filtration when compared to treatment with evaporators.

The Missouri Department of Natural Resources has already been informed of this change in the 51

3.0 Non-Radiological Monitoring Program boron concentration.

This modification will not significantly affect the concentrations, frequencies or types of effluents 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.

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 envrionmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

Callaway Modification RFR 22952 Callaway Modification MP 02-1017 Description of Change:

Description of Change:

This modification installs two sirens on site.

One siren will be installed at stores 2 (construction warehouse) and the second siren will be installed at the water treatment plant building. Each siren is an array of speakers capable of 4800 wafts. The use is to add coverage to the public address system. The siren/speaker array will announce storm warnings and plant emergency conditions as well as the three plant siren sounds, (wail, yelp, and pulse). Each voice message will be less than thirty seconds. Each siren usage should be thirty seconds up to 3 minutes long.

Operations will be sounding the siren from the control room along with/followed by Gaitronics

,announcements.

'Evaluation of Change:

This modificaiton involves an increase in noise from the plant but it is very intermittent and limited in duration. Thus it will not have significant increase in the plant's operational

.noise.

The installation of the loudspeakers will result in minor land disturbance in an area that has already been disturbed from previous construction. No environmental concerns result from this minor amount of land disturbance.

This modification will not significantly affect This request for resolution allows for the use of an alternative design for replacement drift eliminators in the cooling tower. The new design is made from PVC and will replace the asbestos cement board drift eliminators that are currently in use. This review applies to a partial or full replacement of the drift eliminators in the cooling tower. The new design has a lower drift rate when compared to the drift eliminators currently in use.

Evaluation of Change:

The current drift eliminators have a drift rate of 0.02% or 113.6 gpm at design cooling water flow of 586,000 gpm. The new design has a lower drift rate range of 0.003% to 0.0005% which will significantly reduce drift where the new drift eliminators are installed. This will result in less drift and lower the total amount of solids that will be deposited in the area surrounding the Cooling Tower. The result will be less stress on vegetation around the cooling tower from deposited solids.

The lower drift will also result in slightly more solids being retained in the cooling tower basin.

To maintain total dissolved solids in the cooling tower water, it may be necessary to slightly increase discharge from cooling tower blowdown, outfall 002. This change is expected to be less than 1% even if all drift eliminators are replaced.

52

3.0 Non-Radiological Monitoring Program Evaluation of Change - Callaway Modification RFR 22952 (continued):

This is expected to be insignificant with regards to normal coiling tower blowdown and all parameters on the outall are expected to remain essentially the same.

This modification will not significantly affect the concentrations, frequencies or types of efluent 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.
