Abstract This report presents the Callaway Plant Radiological Environmental Monitoring Program (REMP) data obtained from analysis of environmental samples collected in 1995.
Evaluation of radiation levels in the environs around Union Electric Company's (UEC) Callaway Plant involved sampling at strategic points in various exposure pathways. The following types of samples were collected and analyzed; milk, vegetation, surface water, well water, bottom sediment, shoreline sediment, fish, airborne particulates, airborne radioiodine, direct radiation (TLD), soil and wetlands.
Analytical results are presented and discussed along with other pertinent information. Possible trends and anomalous results, as interpreted by Union Electric Company personnel, are discussed.

1.0 INTRODUCTION
This report presents an analysis of the results of the REMP conducted during 1995 for Union Electric Company, Callaway Plant.
l' In accordance with federal and state regulations and the desire to maintain the quality of the local environment, UEC began its radiological monitoring program in April,1982.
The objectives of the REMP are to monitor potential critical pathways of radioeffluent 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 3 E
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.
2.0 RADIOLOGICAL ENVIRONMENT MONITORING PROGRAM 2.1 Program Design The purpose of the operational REMP at Callaway Plant is to assess the impact of plant operation on the environment. For this purpose, samples are collected from waterborne, l
airborne, ingestion and direct radiation pathways. Sampling media are selected which are likely to show effects of p? ant effluents and which are sensitive to changes in radioactivity levels. The types of sample media collected are: milk, surface water, groundwater, shoreline sediment, bottom sediment, soil, wetlands, fish, vegetation, g airborne particulate, airborne radiciodine and direct radiation (TLD). 3 Samples are collected by Union Electric personnel and shipped to Teledyne Isotopes g Midwest Laboratory (TIML) for analysis. TLD's are analyzed by Union E!ectric 5 Personnel. The data obtained are reported monthly and summarized in the annual report.
Environmental sample locations are divided into two types, indicator and control.
Indicator samples are those collected from locations which would be expected to manifest plant effects, if any. Control samples are collected at locations which are expected to be unafrected by plant operation.

Eurface Water Monthly composite samples of surface water from the Missouri River are collected from one indicator location (SO2) and from one control location (sol). The samples are i analyzed for tritium and by gamma spectrometry.
l Ground Water 4
a-Ground water samples are collected quarterly from two on-site wells (F05 and F15) and
)-
one oft-site well used for drinking water (D01). The on-site ground water samples are collected using a manual grab sampler which is lowered into the well. The off-site ground water sample is collected from a faucet after allowing the line to flush for two minutes. Ground water samples are analyzed for Tritium and gamma emitting nuclides.

r Bottom Sediment i
Bottom sediment samples are collected semi-annually 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, l consisting of the uppermost layer of sediment. Each sample is placed, without
' preservative, in a plastic bag and sealed. Bottom sediment samples are analyzed for gamma emitting isotopes.
, Shoreline Sediment .
Shoreline sediment samples are collected semi-annually at the same locations as bottom sediment. The samples are collected within two feet of the waters edge and consist of 2 six inch diameter by two inch deep sediment plugs. Each sample is placed in a plastic bag and sealed. Shoreline sediment samples are analyzed for gamma emitting isotopes.
Wetlands Soil i
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 and sealed. Wetlands soil samples are analyzed for gross alpha, gross beta, and gamma emitting isotopes.
2.2.2 Airborne Pathway 1 Airborne Particulates Airborne particulate samples are collected on a 47mm diameter glass fiber filter type A/E (99 percent removal efficiency at I micron particulate) at a volumetric rate of one and one-half cubic feet per minute at five locations. The particulate filters are collected weekly and shipped to TIML for analyses. The filters are analyzed for gross beta activity approximately five days after collection to allow for decay of naturally-occurring short-lived radionuclides. Quarterly composites of filters by location are gamma-scanned and analyzed for Strontium-89 and Strontium-90.

= I Two gallon milk samples are collected semi-monthly during the pasture season (April through September) and monthly during the winter from one goat and one cow milk location near the Plant (M5 and M6) and one cow milk location away from the Plant l
(M7). Milk samples are shipped in ice to be received by TIML within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of collection. Analyses for Iodine-131, elemental calcium, Strontium-89, Strontium-90, and gamma emitting nuclides are performed on all milk samples.
Etih The five most abundant recreational or commercial fish species are collected semi-annually from one indicator location (C) and one control location (A). Fish B
5 samples are filleted and are analyzed for Strontium-89, Strontium-90 and gamma emitting isotopes.
Vegetation Monthly, during the growing season, green leafy vegetation is collected from two indicator locations (V6 and V9) and from one control location (V3). Vegetation samples consist of mustard greens, turnip greens, cabbage, lettuce, and spinach. The vegetation samples are analyzed for gross alpha, gross beta, Iodine-131, and by gamma spectrometry.
l leil I Once a year soil samples are collected from ten indicator locations (F1, F2, PR3, PR4, PR5, F6, PR7, F8, F9, and PRIO) 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 g location. Samples consist of 2 six inch square soil plugs. The litter at the surface and 5 the root mat is considered part of the sample. The samples are placed in plastic bags and sealed. Each soil sample is analyzed for gross alpha, gross beta, and gamma emitting isotopes.

2.4 Analvtical Procedures Analytical procedures and counting methods employed by the contractor Laboratory follow those recommended by the U.S. Public Health Service publication, Radioassay Procedures for Environmental Samfles. January 1967; and the U.S. Atomic Energy Commission liealth and Safety Laboratory, HASL Procedures Manual. (IIASL-300),
1972.
A synopsis of the routinely used analytical procedures for sample analyses is presented below.
2.4.1 Airborne 2.4.1.1 Gross Beta The glass fiber filter type A/E (99 percent removal efliciency at I micrcn particulate), is placed into a stainless steel planchet and counted for gross beta radioaciivity using a proportional counter.

2.4.1.2 Gamma Snectrometry Filters are composited according to location and counted using a germanium detector gI coupled to a computer based, multi-channel analyzer. The resulting spectrum is W' analyzed by computer and specific nuclides, if present, identified and quantified.
2.4.1.3 Strontium-89 and Strontium-90 The composited filters, with stable strontium and barium carriers added, are leached in nitric acid to bring deposits into solution. After filtration, filtrateis reduced in volume by evaporation. The residue is purified by adding iron and rare earth carriers and precipitating them as hydroxides. After a second strontium nitrate precipitation from nitric acid, the nitrates are dissolved in acid again with yttrium carrier and stored for ingrowth. The yttrium is precipitated as hydroxide and separated from strontium with the strontium being in the supernate. Each fraction is precipitated separately as an oxalate (yttrium) and carbonate (strontium) and collected on a No. 42 (2.4 cm)
Whatman filter. The filters are counted using a low background proportional counter g and the Strontium-90 activity is calculated from the oxalate data. The Strontium-89 g activity is determined by subtracting the calculated Strontium-90 activity from the measured gross strontium activity calculated from the carbonate.
2.4.1.4 lodine-131 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 collection is then calculated. Decay correction for the time g interval between sample collection and counting is then made. W 2.4.2 Direct Radiation Direct radiation measurements are taken by UEC using Thermoluminescent Dosimeters (TLD's). The UEC program employs the Panasonic Model UD-814 TLD and Model UD-710A automatic dosimeter reader. Each dosimeter consists of three elements of CaSO4:Tm and one element of Li 2B407:Cu. The dosimeters are sealed in a moisture resistant plastic bag and placed inside a polypropylene mesh cylindrical holder in the environment. After exposure in the environment the dosimeters are read and the exposure for the time period is determined from the CaSO4:Tm elements. The Li 2B407:Cu element is not used to determine exposure during routine operations.

l 2.4.3 Vegetation 2.4.3.1 Iodine-131 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, multi-channel 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.
2.4.3.2 Gross Alpha and Gross Beta A suitable aliquot of ashed sample is transferred to a two-inch ringed planchet. The planchet is counted for gross alpha and gross beta activity using a proportional counter.
2.4.3.3 Gamma Spectrometry A suitable aliquot of wet (as received) sample is placed into a standard calibrated container and specific nuclides, ifpresent, identified and quantified using a germanium detector coupled to a computer based, multi-channel analyzer.
2.4.4 Milk 2.4.4.1 Iodine-131 Two liters of milk containing standardized Iodine carrier are stirred with anion exchange resin for one hour. The resin is washed with Nacl and the iodine is eluted with sodium hypochlorite. Iodine in the iodate form is reduced to I2and the elemental iodine extracted into CCl4, back-extracted into water, then precipitated as palladium iodide.
The precipitate is counted for I-131 using a proportional counter.
2.4.4.2 Strontium-89 and Strontium-90 One liter of milk containing strontium and barium carriers is passed through a cation-exchange resin column.
Strontium, barium and calcium are eluted from the cation-exchange resin with sodium chloride solution. Following dilution of the eluate, the alkalir.e earths are precipitated as carbonates. The carbonates are then converted to nitrates, and strontium and barium nitrate are precipitated. The nitrate precipitate is dissolved, and barium is precipitated as chromate, purified as chloride, and counted for Barium-140 (if required). From the supernate, strontium is precipitated as nitrate, dissolved in water and reprecipitated as strontium nitrate. The nitrate is converted to carbonate, which is filtered, weighted to determine strontium carrier recovery, and counted for " total radiostrontium" using a proportional counter.
l l
After counting total radiostrontium the second time after six to eight days, Sr-89 concentrations are calculated. If the Sr-89 concentration shows a positive result, the precipitate is dissolved, yttrium carrier added and the sample is stored for six to eight days to allow for additional yttrium ingrowth. Yttrium is separated from strontium, l
precipitated as yttrium oxalate and counted to determine Sr-90 concentrations.
The concentration of Sr-89 is calculated as the difference between the activity for " total radiostrontium" and the activity due to Sr-90.

2.4.4.4 Elemental Calcium Strontium, barium, and calcium are adsorbed on cation-exchange resin, then eluted with sodium chloride solution. An aliquot of the eluate is diluted to reduce the high sodium ion concentration. From this diluted aliquot, calcium oxalate is precipitated, dissolved in dilute hydrochloric acid, and the oxalate is titrated with standardized potassium permanganate.
2.4.5 Surface and Ground Water 2.4.5.1 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.

2.5 Program Modifications During 1995 two modifications were made to the monitoring program. The first modification was the replacement of vegetation sampling location V8 with new location V9. The residence at location V8 was unable to supply the required vegetation samples.
The second change involved relocation of10 TLD sites. TLD sites 1,11,12,15,16, 18,22, 31, and 51 were moved to address safety hazards identified with sample collection activities. Site 30 was moved out of the Missouri River flood plain because of frequent flooding.

4.0 OUALITY CONTROL PROGRAM To insure the validity of the data, the contractor h.boratory maintains a quality control (QC) program which employs quality control checks, with documentation, of the analytical phase ofits environmental monitoring studies. The program is dermed in the Quality Control Program, and procedures are specified in the QC Procedures Manual.
The QC Program includes laboratory procedures designed to prevent g cross-contamination and ensure accuracy and precision of analyses. The quality control u l checks inclode blind samples, duplicate samples, and spiked samples as necessary to I verify laboratory analysis activities are being maintained at a high level of accuracy.
l The Quality Control Program is in compliance with USNRC Regulatory Guide 4.15 and l includes appropriate control charts with specified acceptance levels for instrument source checks, background, efliciency, etc. for counting equipment.
The Laboratory participates in the USEPA Interlaboratory Comparison Program (crosscheck program) by analyzing radioactive samples distributed for that purpose.
The results of the crosscheck program are presented in Appendix B.
5.0 DATA INTERPRETATIONS I In interpreting the data, effects due to the Callaway Plant must be distinguished from those due to other sources.
One interpretation method used in assessment of those effects is the indicator-control concept used in the design of the monitoring program. Most sample types are collected at both indicator locations (areas potentially affected by plant operations) and control locations (areas not affected by plant discharge). A possible plant effect would be indicated if the radiation level at an indicator location was significantly larger than at the controllocation. The difference would have to be greater than what could be accounted for by typical fluctuations in radiation levels arising from other sources.
l An additional interpretation method involves analysis for specific radionuclides present in environmental samples collected around the plant site. For certain isotopes it can be determined if the activity is the result of weapons testing or plant operations because of l
the different characteristic proportions in which these isotopes appear in the fission product mix produced by a nuclear reactor and that produced by a nuclear detonation. l Other means of distinguishing sources of environmental radiation tuat are employed in interpretation of the data. Current radiation levels can be compared with preoperational levels. Results can be related to those obtained in other parts of the country. Finally, g results can be related to events known to have caused elevated levels of radiation in the g environment.
I
6.0 RESULTS AND DISCUSSION Analytical results for the reporting period January to December 1995 are presented in summary form in Appendix D. For each type of analysis ofeach sampled medium, this table shows the annual mean and range for all indicator locations and for all control locations. Results for the location with the highest annual mean are also given.
Discussion of the results is divided into four pathways; waterborne, airborne, ingestion, and direct radiation. The individual saniples and. analyses within each category provides an adequate means of estimating radiation dose to individuals from principal pathways.
Data for individual samples are presented in tabular form in Appendix E.
6.1 Waterborne Pathway The water pathway of exposure from Callaway Plant was evaluated by analyzing surface water, well water, bottom sediment, shoreline sediment and wetlands.
Surface Water Analysis of Tritium in surface water showed detectable activity in three of the samples collected at location SO2 with results ranging from 170 to 689 pCi/1. The mean Tritium concentration at location SO2 was 364 pCi/ liter. The LLDs for other samples ranged from 149 to 171 pCi/l.
No gamma emitting nuclides were detected in any surface water samples.
Levels of activity detected in indicator surface water samples during 1995 were consistent with previously accumulated radiological environmental data and indicate no significant influence from plant operations.
Ground Water in ground water samples, tritium results for all thirteen samples were below the detection limit which ranged from 149 to 173 pCi/1.
No gamma emitting nuclides were detected in any ground water sample.
There was no indication of plant effects on ground water.
I Bottom Sediment Analysis of bottom sediment cc!!ccted in April and October showed positive Cesium-137 activity in one indicator sample with a concentration of 311 pCi!kg. There were no other gamma emitting nuclides detected in bottom sediment samples. The l
l l
I presence of Cesium-137 in bottom sediment exhibits a long term residual effect of previous atmospheric nuclear tests and not an effect from plant operations.
Shoreline Sediment l1 Shoreline Sediment samples were collected in April and October,1995 and analyzed for gamma emitting isotopes. The shoreline sediment sample collected in April at Location A showed Cesium-137 activity of 127 pCi/kg. There were no other gamma emitting nuclides detected in shoreline sediment samples. Similar levels of Cesium-137 activity due to fallout from atmospheric nuclear testing were observed in 1984,1985, and 1987 thm 1994.
Wetlands Analysis for alpha emitters showed detectable activity in all samples, with results ranging from 8190 to 17022 pCi/kg. The average sample concentration at the indicator location was 12088 pCi/kg and at the control location was 12689 pCi/kg.
The aserage gross beta activity in all wetlands samples ranged from 16991 to 37952 pCi/kg. The average activity at the control location was 37952 pCi/kg and at the indicator location was 20484 pCi/kg.
Potassium-40 and Cesium-137 were the only gamma emitting isotopes detected. g Potassium-40 was detected in all samples with results ranging from 12817 to 22647 m pCi/kg. The average concentration for indicator locations was 17647 pCi/kg and for the controllocation was 15143 pCi/kg.
Three wetlands indicator samples showed positive Cesium-137 activity with results ranging from 100 to 292 pCi/kg.
Gross alpha and gross beta activity can be attributed to natr uly occurring isotopes (e.g.
Potassium-40). Similar levels of Cesium-137 activity were observed in previously accumulated data for the wetlands. Cesium-137 activity is expected to be present since the base material for the wetlands is concentrated Missouri River Sediment. The presence of Cesium-137 in river sediment has been identified as a long term residual effect of previous atmospheric nuclear tests.
6.2 Airborne Pathway Airborne pathways of exposure from Callaway Plant were evaluated by analyzing samples of air particulate and air iodine cartridges. .
I l
l Airborne Particulate Gross beta activity in airborne particulate ranged from 0.007 to 0.050 pCi/m3 in all i samples. The average gross beta activity at the indicator and controllocations were 0.024 and 0.023, respectively. The highest annual average (0.027 pCi/m3) was measured at indicator location Al,1.3 miles ENE of the plant.
Gamma spectral analysis of quarterly composites of air particulate filters showed i Beryllium-7 in all twenty samples. The average Beryllium-7 activity for indicator locations was 0.090 pCi/m3 and for controllocations was 0.093 pCi/m3. The presence of Beryllium-7 can be attributed to cosmic ray activity. No other gamma emitting l isotopes ofinterest were detected in the quarterly composities.
Strontium-89 and Strontium-90 analyses performed on quarterly composites indicated no activity above detection limits.
Levels and distribution of activity in air particulate samples are similar to previously I accumulated data and indicate no influence from the plant.
Airborne Iodine I
Airborne Iodine-131 results were below the detection limit of 0.07 pCi/m3 in all samples. Thus, there was no indication of a plant effect.
6.3 Incestion Pathway Potential ingestion pathways of exposure for Callaway Plant were evaluated by analyzing samples of milk, fish, vegetation, and soil.
Milk A total of forty-eight analyses for Iodine-131 in milk were performed during 1995. All samples were below the LLD which ranged from 0.1 to 0.5 pCi/l.
l Naturally occurring Potassium-40 was the only gamma emitting isotope found in milk samples. Concentrations ranged from 920 to 2190 pCi/l. The average concentration for indicator locations was 1500 pCill and for control locations was 1329 pCi/l.
I Strontium-89 results were below the LLD for all samples. The LLDs ranged from 0.4 to I.6 pCi/l Strontium-90 was detected in all milk samples averaging 3.6 pCi/l for I indicator locations and 1.7 pCi/l for control locations. The range of detectable results was 1.1 to 6.0 pCi/l.
Calcium was analyzed in all milk samp!cs with levels ranging from 0.72 to 1.18 gm/l.
l W
In summary, the milk data for 1995 show no radiological effects from plant operation.
The presence of Strontium-90 in milk samples exhibits a long range residual effect of previous atmospheric nuclear tests.
Fish l
The types of fish species collected during 1995 were: Carpsucker, Channel Catfish, Flathead Catfish, Bigmouth Buffalo, Shortnose Gar, Shorthead Redhorse, Freshwater Drum and Carp.
All fish samples indicated positive Potassium-40 activity with levels ranging from 2145 pCi/kg-wet to 3408 pCi/kg-wet. The mean Potassium-40 activity was 2884 pCi/kg-wet for the indicator location and 2965 pCi/kg-wet for the control location. No other gamma emitting isotopes ofinterest were detected in the fish samples.
No Strontium-89 or Strontium-90 activity was detected in fish samples collected during 1995.
Activities detected in fish samples were consistent with levels and fluctuations of
, previously accumulated environmental data. It can be concluded that operation of the plant has had no affect on fish samples.
Vegetation Vegetation samples collected during 1995 consisted of mustard greens, turnip greens, lettuce, cabbage, and spinach. The number of vegetation samples collected in 1995 were lower than in past years. This reduction in samples was due to extensive rain during the spring and unusually dry conditions in late summer.
Gross alpha activity was observed in eighteen of the twenty vegetation samples with I
results ranging from 84 to 323 pCi/kg-wet. The average activity for indicator locations was 192 pCi/kg-wet and for the control location was 144 pCi/kg-wet.
\
Gross beta activity was detected in all vegetation samples with results ranging from g 2863 to 5677 pCi/kg-wet. The average gross beta activity for indicator locations was E 4371 pCi/kg-wet and for the controllocation was 3321 pCi/kg-wet.
lodine-131 activity was below the detection limit in all samples.
Naturally occurring Potassiurn-40 was found in all vegetation samples. Concentrations ranged from 2945 to 6367 pCi/kg-wet and averaged 4593 and 3566 pCi/kg-wet at indicator and control locations respectively. All other gamma emitting isotopes were below their detection limit.
I
i Levels of activity detected in vegetation samples were consistent with previously accumulated data and no plant effect was indicated.
I =
Gross alpha results ranged from 8680 to 24267 pCi/kg for all eleven samples. The mean I activity for indicator locations was 14139 pCi/kg and for the control location was 15007 pCi/kg. Gross beta activity was detected in all eleven samples ranging from 18986 to l 24026 pCi/kg. The average gross beta activity was 21995 and 23666 pCi/kg at I indicator and control locations respectively.
Gamma spectral analysis of the soil samples showed Cesium-137 and Potassium-40 in all I samples. Cesium-137 results ranged from 190 to 1496 pCi/kg. The average concentration was 985 pCi/kg at the indicator locations and 190 pCi/kg at the control location. Potassium-40 results ranged from 10621 to 17181 pCi/kg. The average concentration for indicator locations was 12302 pCi/kg and for the control location was 17181 pCi/kg.
I The gross alpha and gross beta activity can be attributed to naturally occurring isotopes (e.g. Potassium-40). Cesium-137 activity present can be attributed to werldwide fallout l from atmospheric nuclear testing. The level of activity and distribution pattern is similar to previously accumulated data and indicates no influence from the plant.
6.4 pirect Radiation All TLD results presented in this report have been normalized to a 90-day quarter I (standard quarter) to eliminate apparent differences in data caused by variations in length of exposure period.
The range of quarterly TLD results for indicator locations was Il.4 to 22.2 mrem / standard quarter and 15.7 to 19.1 mrem / standard quarter for control locations.
Qaarterly TLD analyses yielded an average exposure level of 17.6 mrem / standard I quarter at all indicator locations and an average exposure level of 17.1 mrem / standard quarter at all control locations.
The annual TLD results ranged from 12.3 to 19.9 mrem / standard quarter. The average exposure levels were nearly identical at the indicator and control locations (17.4 mrem / standard quarter and 17.1 mrem / standard quarter, respectively).
There was no significant difTerence between indicator and control locations for the TLD's during 1995. The exposure levels were consistent with previously accumulated data and no plant efTects were indicated.

In accordance with Technical Specification 6.8.4.f and APA-ZZ-01003, Offsite Dose Calculation Manual (ODCM), a Land Use Census is performed annually during the growing seasonThe within a 5 mile radius of Callaway Plant.
Land Use Census is conducted to identify the location of the nearest resident, the nearest milking animal, and the nearest garden of greater than 50 m8 producing broad leaf vegetation in each of the 16 meteorological sectors. The results of this census are used to identify changes in the use of the area at and beyond the SITE BOUNDARY that would require modification to the existing monitoring programs presented in the ODCM.
The 1995 Land Use Census was conducted during August and September by the Union Electric Real Estate Department. Information was collected by contactingsfamilies identified in the 1994 Land Use Census and field surveys conducted within a 5 mile radius of the plant site noting the location of the above mentioned items.
2.0 RESULTS Results of the Land Use Census are presented in Tables 1 through 3 and discussed below. The tables include radial direction and distance from the Callaway Plant for each location. The radial direction is one of the 16 different compass points. Mileage was estimated from map position for each location.
Changes identified in this year's Land Use Census did not require modification to the monitoring programs used to evaluated dose to the public from principle pathways of exposure.
2.1 Nearest Resident Table 1 presents the location of the nearest resident to Callaway Plant in each of the 16 mateorological sectors. There were three changes noted in the 1995 census. None of the changes ob=9cved required a change to the location of the neares- resident yielding the highest calculated dose ccvmitment.

I 2.2 Milkino Animals Table 2 presents the location of the nearest milking animals identified within a 5 mile radius of Callaway Plant. All milking animals, whose milk is not used for human consumption and/or not 3 yielding milk, are shown on Table 2. There were 3 two location changes observed during this years census, which involved the identification of a new location in the SW sector and deletion of a previous identified location in the S sector. In addition, several other changes were noted this year in the number and types of milking animals 3 observed. The changes identified are normal for 3 a rural area where milking animals are bought and sold on a routine basis. None of the changes E noted resulted in modification to the current milk monitoring program.
5 2.3 vecetable Gardens Locations of the nearest vegetable garden greater than 50 m2 producing broad leaf vegetation are g presented in Table 3. Six changes in the g location of the nearest garden were observed during this year's census. Most of the changes noted were related to the extensive rain and flooding during the spring of 1995 which prevented many residents from having gardens.
None of the changes identified resulted in changes to the current vegetable sampling locations.

THE AVERAGE OF THE SAMPLES I COUNTED ON THE OTHER DAY (NOT REPORTED) WAS LOW, BUT WOULD HAVE PASSED. TELEDYNE HAS N0 1 EXPLANATION FOR THE LOW VALUES NORMALLY TELEDYNE WOULD REANA-LYZE THE SAMPLE. IN THIS IN-I STANCE APPROXIMATELY 18 HALF-LIVES HAVE TRANSPIRED SINCE COLLECTION. TELEDYNE FELT PRE-PARING AN IN-HOUSE SPIKE WOULD l BE MORE ADVANTAGEOUS. AN IN-HOUSE SPIKE WAS PREPARED ON 02-08-96. THESE RESULTS WERE I ACCEPTABLE. THE TECHNICIAN WAS OBSERVED PERFORMING THIS ANALYSIS WITH NO PROBLEMS NOTED. SINCE THIS IS THE FIRST I INSTANCE OF POOR PERFORMANCE IN THIS ANALYSIS, NO FURTHER-ACTION IS PLANNED. TELEDYNE I WILL MONITOR THIS ANALYSIS FOR FUTURE PROBLEMS.

hotopic Detection Limits and Activity Determination Making a reasonable estimate of the limits of detection for a counting procedure or a radiochemical method is usually complicated by the presence of significant background.
It must be considered that the background is not a fixed value but a series of replicates normally distributed. The desired net activity is thus the difference between the gross sample activity and background activity distributions.
( The interpretation of this difference becomes a problem if the two distributions intersect as indicated in the diagram.
f BACKGROUND GROSS f
( ________- __
If a sumcient number of replicate analyses are run, it is to be expected that results would fall in a normal Gaussian distribution. In routine analysis such replication is not carried out. Standard statistics allow an estimate of the probability of any particular deviation from the mean value. It is common practice to report the mean
- one or two standard deviations as the final result.
Analytical detection limits are governed by a number of factors including:
( l. Salmple Size
- 2. Counting Efficiency
[
The ftmdamental quality in the measurement of a radioactive substance is the number of disintegrations per unit time. As with most physical measurements in analytical chemistry, it is seldom possible to make an absolute measurement of the disintegrations rate, but r r ther, it is necessary to compare the sample with one or more standards The standards L
determine the counter efliciency which may then be used to convert sample counts per minute (cpm) to disintegrations per minute (dpm).
C-1
Il
- 3. Background Count Rate Any counter will show a certain counting rate without a sample in position. This g background counting rate comes from several sources: 1) natural environmental radiation a from the surroundings, 2) cosmic radiation, and 3) the natural radioactivity in the counter materialitself. The background counting rate will depend on the amount of these types of radiation and sensitivity of the counter to radiation.
- 4. Background and Sample Count Time EI El I The amount of time devoted to counting background depends on the level of the activity !
being measured. In general, with low level samples, this time should be about equal to l
that devoted to counting a sample.
l S. Time Interval Between Samole Collection and Counting I g'
l Decay measurements are useful:a identifying certain short-lived isotopes. This disintegration constant is one of the basic characteristics of a specific radionuclide and is 3 readily determined, if the half-life is sufliciently short.
- 6. Chemical Recovery of the Anahtical Procedure Most radiochemical analyses are carried out in such a way that losses occur during the g separations. These losses occur due to a large number of contaminants that may be E present and interfere during chemical separations. Thus it is necessary to include a technique for estimating these losses in the development of the analytical procedure.
The following method was used to determine lower limit of detection (LLD) as 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, for purposes of this guide, 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 l falsely concluding that a blank observation represents a "real" signal.
For a particular measurement system (which may include radiochemical separation):
I ss LLD =
E
- V
- 2.22
- Y
- exp(-Mt)
I I-C-2 {

Where:
LLD =
" A priori lower limit of detection as defined above (pCi per unit mass or volume).
=
sb Standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (counts per minute).
E =
Counting efficiency (counts per disintegration).
V =
Sample size (units of mass or volume).
2.22 =
Number of disintegrations per minute per picocurie.
Y =
Fractional radiochemical yield (when applicable).
=
A. Radioactive decay constant for the particular radioisotope.
At =
Elapsed time between sample collection (or end of the sample collection period) and time of counting.
The value of sb used in the calculation of the LLD for a particular measurement system is based on the actual observed variance of the background count rate, or, the counting rate of the blank sample, (as appropriate), rather than an unverified theoretically predicated variance.
In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background includes the typical contributions of other nuclides normally present in the samples.
Sinule Measurements Each single measurement is reported as follows:
xis where: x = Value of the measurement; s = 2c counting uncertainty (corresponding to the 95% confidence level).
In cases where the activity is found to be below the lower limit of detection L it is reported as
<L where L = the lower limit of detection based on 4.66c uncertainty for a background sample.

In rounding off, the following rules are followed:
- 1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are unchanged. As an example,11.443 is rounded off to 11.44.
- 2. If the figure following those to be retained is greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example,11.446 is rounded off to 11.45.
- 3. If the figure following those to be retained is 5, and if there are not figures other than zeros beyond the five, the figure 5 is dropped, and the last-place figure retained is increased by one ifit is an odd number or unchanged if an even number.
As an example,11.435 is rounded off to 11.44, while 11.425 is rounded off to 11.42.

Defmition of terms used in the data tables are as follows:
Wet Weight A reporting unit used with organic tissue samples such as vegetation and animal samples in which the amount of sample is taken to be the weight as received from the field with no moisture f
removed.
Dry Weight A reporting unit used for soil and sediment in which the amount of sample is taken to be the weight of the sample after removal of moisture by drying in an oven.
pCi/m3 A reporting unit used with air particulate and radioiodine data which refers to the radioactivity content expressed in picocuries per cubic meter of air passed through the filter and/or the charcoal trap.
Note the volume is not corrected to standard conditions. .
Gamma Emitters Samples were analyzed by high resolution (GeLi) gamma or spectrometry. The resulting spectrum is analyzed by a computer f Gamma Isotopic program which scans from about 50 to 2000 kev and lists the energy peaks of any nuclides present in concentrations exceeding the sensitivity limits set for that particular sample.
Error Terms Figures following " *" are error terms based on countag uncertainties at the 95 percent confidence level. Values preceded by the "<" symbol were below the stated concentration a: the 99
, percent confidence level.
Sensitivity In general, all analyses meet the sensitivity requirements of the program as given in Table III. For the few samples that do not (because ofinadequate sample quantities, analytical interference, etc.) the sensitivity actually obtained in the analysis is given.

1.0 INTRODUCTION
Union Electric Company (UEC), in accordance with federal regulations and the desire to maintain the quality of the local environment around the 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 nonradiological environmental values during operation of the Callaway Plant.
i This report describes the conduct of the EPP for the Callaway Plant during 1995.
2.0 UNUSUAL OR IMPORTANT EVENTS I No unusual or important events reportable under EPP Section 4.1 were identified during 1995.
I 3.0 EPP NONCOMPLIANCES During 1995 there were no noncompliances with the EPP.
4.0 NONROUTINE REPORTS There were no nonroutine reports submitted in accordance with EPP, Section 5.4.2 in 1995.
5.0 PLANT DESIGN AND OPERATION ENVIRONMENTAL EVALUATIONS This section lists all changes in plant design, operation, tests or experiments completed during 1995 which could have involved a potentially significant l unreviewed environmental question in accordance with section 3.1 of Appendix B.
During 1995 there were thineen plant design and operation changes that could have l involved a poteitially significant unreviewed environmental question. The interpretations and conclusions regarding these plant design and operation changes along with a description of the changes are presented below.
I s -
5.1 Il Callaway Modincation Package 89-3001 i 5.1.1 Description of Change I' This change replaced the existing sodium hypochlorite addition system. The new equipment is located in the circulating water pump house and feeds 12 % sodium i hypochlorite. This change also eliminated outfall 008 by permanently capping all g' drain lines in the circulating water pump house. This modification was necessary E because the previous sodium hypochlorite addition system was unreliable as well as ,
uneconomical to operate.
5.2.2 Evaluation of Chance All construction activities were conUned to the inside of existing plant stmetures.
The installation of this design change reduced the likelihood of a large spill of hypochlorite to the environment in violation of the plant NPDES Permit. This change also eliminated any future discharge through outfall 008. The installation of l the equipment and the use of 12% sodium hypochlorite was reviewed and approved g by the Missouri Department of Natural Resources. Therefore, this change did not g constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
5.2 Callaway Modification Package 95-2010 5.2.1 Descriotion of Chance This change involved installation of additional piping from the plant neutralization tank to the water treatment plant equalization basin. This modification allows efnuent from the neutralization tank to be mixed directly with water in the equalization basin, allowing for better control of the effluent that could be discharged.
5.2.2 Evaluation of Change All construction activities were confined to areas already disturbed during plant g constmetion. No cultural resources are located in this area. This piping change did 3 not affect concentrations, frequencies or types of efnuents from the water treatment plant. EfDuents from this outfall are still within the limits designated in the g NPDES Permit. Therefore, this change did not constitute an unreviewed 5, environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License, l

5.3 Callaway Modification Packaee 95-3002 5.3.1 Description of Change This modification relocated the downstream river sampler pump to a new pump p vault installed near the existing sample station house. In addition, the sample line
\ intake located in the river was raised to reduce the silt intake by the sampling system. This change was needed to improve the reliability of the sample station to collect a composite river sample required by the radiological environmental
{ monitoring program.
5.3.2 Evaluation of Change
{
Constmetion was on land previously disturbed during initial sampler construction f and did not contain any cultural resources. Therefore, this change did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
5.4 Reauest for Resolution 09220C 4
1 5.4.1 Descrintion of Change j This change involved installation of an above ground diesel fuel storage tank and I
secondary containment plant west of the stores building. This tank replaced the existing diesel fuel storage tank which was removed from the plant site.
5.4.2 Evaluation of Change The removal of the existing diesel fuel storage tank and the installation of the above ground diesel fuel storage tank did not result in any adverse environmental impact, since all measurable non-radiological effects were cont'ined to the areas previously
( disturbed during site preparation and plant constmetion. Removal of the existing storage tank was performed according to the applicable regulations.
The above ground diesel fuel storage tank is enclosed in a secondary containment with capacity of greater than 150% of the largest storage compartment in the storage tank, providing sufficient freeboard to allow for the largest anticipated rainfall event.
Therefore, this change did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
5.5 R
. ecuest for Resolution 15336B 5.5.1 Description of Change This change involved installation and use of a recoven well and monitoring wells inside the protected area of the plant. The installation of these wells are addressed in the Callaway Plant Diesel Fuel Recoveg Corrective Action Plan. This plan addresses the remediation and corrective actions for the diesel fuel oil leak from the underground transfer piping to the auxiliary boiler which occurred in 1993. l 5.5.2 Evaluation of Change The installation of these wells did not result in a significant increase in any adverse g environmental impact, since all measurable non-radiological environmental effects E were confined to areas previously disturbed during plant construction. No cultural resources are located in the area.
The wells were drilled through the backfill to depths not exceeding the thickness of the backfill material to prevent penetrating the Graydon Chert which is a natural barrier. The wells have the capability to monitor and extract perched groundwater trapped within the backfill material. All wells were installed according to the Missouri well construction rules.
Therefore, this change did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
5.6 Reauest for R_q_ solution 16125A 5.6.1 Descriotion of Chance This change allowed treatment of the stator cooling water, main turbine lube oil, and closed cooling water heat exchanges to prevent Microbiological Induced Corrosion (MIC). Three chemicals are used to treat these systems, BULAB 6011 (a g nonoxidizing biocide), BULAB 8006 (a biopenetrant), and BULAB 9605 W (diethydroxylamine) which is an oxygen scavenger and used for pH control.
I I
I I
5.6.2 Evaluation of Chance With the heat exchangers in wet layup, the chemicals are added and recirculated in the heat exchanger using a potable chemical addition skid pump. The chemicals are added to the heat exchangers to achieve BULAB 8006 concentrations of 25-50 ppm as product, BULAB 6011 concentrations of 50-75 ppm as product, and BULAB 9605 concentrations of 50-100 ppm as product. The concentrations are verified monthly. If these chemicals were to mix with service water the concentration in the cooling tower basin wculd be less thap 0.2 ppm. BULAB 8006 and 6011 have previously been reviewed and found acceptable for use by the Missouri Department of Natural Resources (DNR). The Missouri DNR was notified of our intent to use BULAB 9605 and had no objections. Therefore, this change did not constitute an I unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
5.7 Request for Resolution 16125A and Plant Procedure CTP-EF-06102. Rev. 0 5.7.1 Description of Change This change and procedure n: vision allowed a new non-oxidizing biocide, BULAB 6010, to be added to the Essential Service Water System (ESW) for control of Microbiological Induced Corrosion (MIC).
5.7.2 Evaluation of Change I
Approximately 10 gallons of BULAB 6010 is added to one train of the ESW system at the pump suction every two weeks to achieve a maximum concentration of 20 I ppm. During treatment, the ESW pumps were discharged back into the ultimate heat sink. Any treated water that remains in the ESW system following treatment I goes to the cooling tower basin and is discharged through outfall 002. The discharge concentration is estimated to be 0.009 mg/l on the day of treatment.
I The Missouri Depanment of Natural Resources was notified of our intent to use the new non-oxidizing biocide and had no objections. Therefore, this change did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
E
I 5.8 Temocrary Modification 95-M005 I
5.8.1 Description of Change Il Temponry Modification 95-M005 allowed the use of a tempomry laundry facility for cleaning protective clothing during Refuel 7. Ozone was used in the cleaning process as a cleaning and disinfecting agent as in past outages. This clean process was previously reviewed by Request for Resolution 10604 which was described in i the 1993 Annual Environmpntal Operating Report.
5.8.2 Evaluation of Change Ozone was generated using a pure water oxytech ozone generator and fed into two mixing tanks at a rate of 160 cubic feet per hour. A portion of the ozone was dissolved in the water while the remaining ozone in the tanks was discharged to the atmosphere through a charcoal bed and HEPA filter. The charcoal bed converts the ozone to oxygen. Ozone was also applied to the washing machines to optimize the cleaning process. Minor amounts of ozone were discharged from the washing machines through a HEPA filter into the trailer and to the atmosphere.
l Waste water from the process was routed to a holding tank. Approximately 100 gallons of waste laundry water per day was discharged to the auxiliary building floor drain after the tank was sampled. This water was then processed and discharged to the Missouri River. Due to the holdup time and short half-life for g ozone, there was no ozone present in the water received by the discharge g monitoring tanks.
Although small quantities of ozone could be released from the trailer to the atmosphere, no pennits or approval was required for this release by the Missouri Department of Natural Resources (DNR). However, DNR was notified of this temporary process used at Callaway. Therefore, this change did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
5.9 Plant Procedure CTP-AO-06100. Rev. O 5.9.1 Descrintion of Chance I
Procedure CTP-EF-06100 was prepared to allow the addition of titanium dioxide (TiO2) to the steam generators during wet layup and during the passivation steps following steam generator chemical cleaning. Titanium dioxide is used as a corrosion inhibitor.
6-
l l
5.9.2 Evaluation of Chance Approximately 2 pounds of titanium dioxide (TiO2) was added to each steam generator during wet layup and an additional 2 pounds of TiO2 was added to each steam generator during the passivation soak. During normal operations, TiO2 is t injected continuously into the steam generators at a rate of approximately 10 pounds per year. Experience has shown that greater than 80% hideout in the steam generators can be expected. A small amount of TiO2 is collected on the condensate polishers during operation and is back-washed to secondary liquid waste. A small amount of TiO2 could be discharged through outfall 001. The Missouri Department of Natural Resources was notified of our intent to use TiO2 and had no objections. Therefore, this change did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.

I 5.10.1 Description of Change i
. i These procedures were initiated to address the pressure pulse chemical cleaning of the steam generators and the storage of chemicals used during the cleaning process.
These procedures also covered storage of the waste generated during the cleaning process.
5.10.2 Evaluation of Chance Chemical cleaning of the steam generators was conducted during Refuel 7. This cleaning process included an iron solvent cleaning step, a copper solvent cleaning step along with several bundle flushes and rinses. During the cleaning bursts of nitrogen were pulsed into the bottom of the tube bundle to provide mixing and aid in the cleaning process. Throughout the cleaning process the steam generators were vented intermittently to atmosphere using the steam genemtors power operated relief valves (PORV's). During the cleaning process, the waste cleaning solution, bundle flushes and rinses were collected in 20,000 gallon steel frac tanks located next to the radwaste building.
The Missouri Department of Natural Resources (DNR) was notified of our intent to perfonn the chemical cleaning and of the waste that was generated by this process.
The DNR had no objections to the chemical cleaning process or waste generated.
Therefore, this change did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
I 5.11 Onerating License Chanee Notice 1152 I
5.11.1 Description of Changs This involved changes to the Operating License to incorporate installation of the Recirculation Fluid pH Control System (RFPC) and retirement of the Spray Additive System.
5.11.2 Evaluation of Change With the retirement of the spray additive system, sodium hydroxide usage at the plant has decreased below the quantities previously identified. The RFPC installed uses trisodium phosphate dodecahydrate (TSP-C) for pH control. The TSP-C is g contained in wire baskets in the containment emergency sumps. The expected loss 3 of TSP-C from these containers is estimated to be 25 pounds per year which relate to a concentration in the radwaste effluent of 0.11 mg/1. This calculation assumes that none of the phosphates are removed by the mdwaste system.
The NPDES Permit specifically indicated there was no discharge of phosphates from the radwaste ef fluent outfall 001. Should there be a spill or leak of TSP-C in containment, there is a chance TSP-C could end up in the containment sumps. The effluent from the containment sump is processed by the radwaste system before discharge. There is a remote chance that some tnce amounts of TSP-C could be discharged through outfall 001. Because of this possibility, the Missouri Department of Natural Resources (DNR) was notified that there may be trace amounts of TSP-C in outfall 001. The DNR had no objections to the change.
Therefore, this change did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
5.12 Suggestion Oqqurrence Solution 95-0610 5.12.1 Descrintion of Change During Refuel 7 the auxiliary boiler was found to contaminated with radioactive material resulting in the release of radioactive material to the environment from a normally non-radioactive system. An evaluation to allow continued operation of the auxiliary boiler was documented in a 50.59 evaluation for the subject SOS I

5.12.2 Evaluation of Chance This event resulted in discharge of steam to the atmosphere containing low levels of radioactive material. All releases to the atmosphere were within NRC regulatory l
' limits and plant administrative limits specified in the Offsite Dose Calculation i Manual (APA-ZZ-01003). All liquid releases from the auxiliary boiler and area floor drains were routed to the liquid radwaste system for processing before release to the environment. A 10CFR50.59 evaluation and environmental evaluation were completed to allow operation of the auxiliary boiler in a contaminated state as required by NRC I & E Bulletin 80-10. Therefore, this event did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway l
. Plant Operating License.
5.13 Suggestion Occurrence Solution 95-1940 5.13.1. Description of Chanee An environmental impact review was completed of a break in the plant discharge line and subsequent liquid release to Logan Creek. On October 9,1995 a report was made to the control room that them was a water leak between Iogan Creek and Highway 94. The outside equipment operator discovered a leak in the discharge ,
line from the plant. The water was running into Logan Creek and back into the Missouri River.
5.13.2 Evaluation of Change This event resulted in the discharge of liquid effluents from the plant into Logan Creek from a break in the plant discharge pipe. All liquids released to Logan Creek were within NRC regulatory limits and the limits specified in the Callaway l
Plant NPDES Permit. Environmental monitoring and observations after discovery of the pipe break did not identify any significant increase in any adverse environmental impact. In addition, the location of the pipe break did not impact <
any cultural resources and was in an area previously disturbed during Plant construction. Therefore, this event did not constitute an unreviewed environmental question per Section 3.1 of Appendix B to the Callaway Plant Operating License.
