SUMMARY
I This Annual Radiological Environmental Operating Report describes the l McGuire Nuclear Station Radiological Environmental Program and the results I of the program for the calendar year 1990. Included in the report are identification of sampling locations, descriptions I of environmental sampling and analysis procedures, comparisons of present environmental radioactivity levels and preopntational environmental data, i analysis of trends in the environmental rad!oactivity levels sirwe the E beginning of station operation, comparisons of doses calculded from 5 environmental measurements and doses calculated from effluent data, a summary of the results of the 1990 program, discussion of the results, and l I discussion of the quality assurance activities associated with the program. Deviations from program requirements are also included. Supplemental samples also were taken in addition to the required sampling locations. Sampling activities were . conducted as prescribed by Technical Specifications. Required analyses were performed and detection capabilities met Technical Specification requirements. Supplemental samples also were ' taken in addition to the required sampling locations. Concentrations observed in the environment in 1990 for station related I radionuclides were within the ranges of concentrations observed in the past. All positive indications of radioactivity due to plant operations were less than the reporting levels specified by the Nuclear Regulatory 1 Commission (NRC) and given in Technical Specifications. I Statistical analysis of lata indicates that McGuire Nuclear Station has contributed to the tritium (11-3) concentration in drinking water; the i probability for increasing the trend was high to moderate. However,the 1990 drinking water H-3 concentration was a small fraction of the reporting level and the maximum annual dose contribution was only 0.0125 mrem. All
)
I other possible trends had moderate to no probability. It can be concluded that the contribution of McGuire to the radioactivity in the environment is slight . l I I I I I l 1-1

2.0 INTRODUCTION
I g 2.1 SITE DESCRIPTION AND SAMPLE LOCATIONS McGuire Nuclear Station is located geographically near the center of the I highly industriallred region of the Carolinas. The land is predominantly rural non-farm with a small amount of land being used to support beef cattle and farming. Recreation in the area is confined mostly to the lake and I shores of Lake Norman and Mountain Island reservoir. The McGuire site is in northwestern Mecklenburg County, North Carolina,17 miles north-northwest of Charlotte, North Carolina. The site is bounded to the west by l the Catawba River channel and to the north by the 32,510 acro Lake i I Norman. Lake Norman is impounded by Duke Power Company's Cowans Ford ! Dam Hydroelectric Station, which is located immediately west of the site and l on the Catawba River channel. The ta!! water of Cowans Ford Dam is the upper limit of Mountain Island Reservoir. Mountain Island Dam is located 15 miles downstream from the site. Lookout Shoals Hydroelectric Station is at the upper reaches of Lake Norman. Marshall Coal Station is located on l the western shore of Lake Norman, approximately 16 miles upstream from the site (reference 6.2 and 6.3). The sites exclusion radius is 2500 feet. l E Tables 2.1-A and 2.1-B define the sampling and TLD locations for the ! , 5 McGuire Radiological Monitoring Program. Figures 1 and 2 illustrate these ! locations as compared to McGuire Nuclear Station. I I I i

E I 2.2 SCOPE AND REQUIREMENTS OF ENVIRONMENTAL MONITORING PROGRAM I An environmental monitoring program has been in effect at McGuire Nuclear Station since 1977, four years prior to the Unit No. I startup in 1981. The I preoperational program provided data on the existing environmental radioactivity levels for the site and vicinity which may be used to determine whether increases in environmental levels are attributable to the station. The operational program provides surveillance and backup support of detailed effluent monitoring which is necessary to evaluate the significance, if any, of the contributions to the existing environmental radioactivity levels that result from station operation. This monitoring program is based on NRC guidance as reflected in Technical Specifications 3/4.12 with regard to sample media, sampling locations, i sampling frequency, and analytical sensitivity requirements. Tables 2.2-A and 2.2-B show the maximum values for LLD and the reporting levels, respectively, from Technical Specifications. Table 2.2-C shows the analysis I schedule for each medium and the type of analysis required. Indicator and control locations were established for comparison purposes to distinguish radioactivity of station origin from natural or other " man-mad e" environmental radioactivity. The environmental monitoring program also I verifies projected and anticipated radionuclide concentrations in the environment and related exposures from releases of radionuclides from McGuire Nuclear Station. This program provides surveillance of all i appropriate critical exposure pathways to man and satisfies vitalinterests of the company, public, and state and federal agencies concerned with the environment.

I I 2.3 STATISTICAL AND CALCULATIONAL METHODOLOGY I 2.3.1 ESTIMATION OF THE MEAN VALUE There was one (1) basic statistical calculation performed on the raw data resulting from the environmental sample analysis program The calculation involved the determination of the mean value for the intucator and the I control samples for each sample medium. The mean is a widely used statistic. This value was used in the reduction of the data generated by the sampling and analysis of the various media in the Environmentul Monitoring Program. The following equation was used to estimate the mean: I {x N 1 (eq. 2-1) 73"1" l I Where: 5 = estimate of the mean, i = individual sarrule, N = total number s t samples with a net activity (or concentration) I x, = net activity (cr 'oncentration) for sample 1. NOTE: " Net activity (or concentration)" is the activity (or I concentration) determined to be present in the sample. No
" Minimum Detectable Activity", " Lower Limit of Detection", "Less Than Level", or negative activities or concentrations are ,
included in the calculation of the mean. 2.3.2 LOWER LEVEL OF DETECTION AND MINIMUM DETECTABLE ACTIVITY
-I The Lower Level of Detection (LLD) and Minimum Detectable Activity (MDA) are used throughout the Environmental Monitoring Program, both in the Technical Specifications and in the implementation of the specifications.
The LLD, as defined in the Technical Specifications, is the smallest concentration of radioactive materialin a sample that will yield a net count, I- 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 LLD is an a priori lower limit of detection. The actual I LLD is dependent upon the standard deviation of the background counting rate, the counting efficiency, the sample size (mass or volume), the l radiochemical yield, and the radioactive decay of the sample between sample l collection and counting. The " required" LLD's for each sample medium and selected radionuelldes are given in the Technical Specifications. lI The MDA may be thought of as an " actual" LLD for a particular sample measurement remembering that the MDA is calculated using a sample 2-10 i
I background instead of a system background. In gamma spectroscopy analyses , the sample background may be elevated above the system background due to the continuum produced by higher energy gammas from I other radionuclides (either man-made or naturally produced). The continuum increases the smallest concentration of a particular radionuclide that could be positively identified in the sample. Therefore, to insure that I the " required" LLD is not exceeded for any radionuclide in a sample medium, the MDA is calculated based on the actual background in the area of the identifying gamma energy and is compared to the " required" LLD. I If the MDA nxceeds the " required" LLD, the sample is counted for a longer time period so that the standard deviation of the sample backgr'ound is minimized. If the " required" LLD exceeds the MDA, then the analysis of the sample meets the requirements for the detection capability for environmental I sample analysis. For " gross" counters (such as alpha / beta proportional counters and liquid I scintillation counters), the MDA is calculated using a batch background count. This MDA is then compared to the " required" LLD. If the MDA exceeds the " required" LLD, the sample is counted for a longer time period so that the standard deviation of the batch background is minimized. If the I " required" LLD exceeds *.he MDA, then the analysis of the sample meets the requirements for the detection capability for environmental sample analysis. I 2.3.3 TREND IDENTIFICATION I One of the purposes of an environmental monitoring program is to determine if there is a buildup of radionuclides in the environment due to the operation of the nuclear station. This is traditionally done by looking at historical II data (including preoperational data) and determining if a trend exists. Trends, if they exist, may be either positive or negative. Since nuclear reactor operations do not normally remove radioactivity from the surrounding environment, a negative trend in a particular radionuclide's ,I concentration in an environmental medium does not indicate that reactor operations are removing radioactivity from the environment but that reactor operations are not adding that radionuclide to the environment in quantities exceeding the preoperational level and that the normal removal processes l (radioactive decay, deposition, resuspension, etc.) are influencing the l concentration. In some cases, visual inspection of tabular or graphical presentations of data may be sufficient to determine if a trend exists, in other cases, it may not be so obvious. Therefore, it is desirable to obtain a single numerical I value from the data which will permit a meaningful interpretation of the relationship existing between the variations in the data. If it is assumed that a linear relationship exists between the time after startup of the reactor I and the amount of radionuclides in a particular environmental medium, the lease squares regression method may be used to define the linear relationship. To determine if the data actually correlate to the straight line I assumption, the theoretical variance is compared to the actual variance. The numerical value that summarizes this comparison is known as the correlation coefficient. This correlation coefficient, symbolized by "r", is a determination of how closely the data fit a straight line and may be I calculated from the equation on the next page: 2-11
I I NEXY-EXE Y y 2 [(NEX .(3y)2)(y3 y2-(E y)2)] (eq. 2-2) I Where: r = correlation coefficient for the data set of X and Y, X = the year or point in time, I Y = the radionuclide concentration associated with X, N = number of observations. l l I The range of values as calculated by the correlation coefficient lies between positive on (+1) and negative on (-1) . The absolute value of the correlation I coefficient represents the probability of a trend. Zero (0) represents no indication of either a positive or negative trend. A positive (+) correlation coefficient indicates an increasing trend, and conversely, a negative (-) I correlation coefficient indicates a decreasing trend. The ranges of a correlation coefficient may be summarized as following: l j I 1> lrl > 0.7 High to moderate probability of a trend. 0.7 3 Irl > 0.3 Moderate to poor probability of a trend. !
- 0. 3 [ l r l >_ 0 Poor to no probability of trend.
Identifying a trend by using the correlation coefficient is only useful for the I time periods where the discharge from the nuclear plant is relatively stable and no other sources of radioactivity are present. Substantialincreases or decreases in the amount of a particular radionuclide's release from the I nuclear plant will greatly affect the resulting environmental levels; therefore, a knowledge of the release of a radionuclide from the nuclear plant is necessary to completely interpret the trends, or lack of trends, I determined from the environmental data. Other factors that may affect environmental levels of radionuclides include prevailing weather conditions (periods of drought or heavier than normal precipitation), construction in or around olther the nuclear plant or the sampling location, addition or I deletion of other sources of radioactive materials (such as the Chernobyl accident), etc. . Some of these factors may be obvious while others are sometimes unknown to the plant personnel. The recent change in the method of calculating the mean (using only net positive results) will also affect the apparent trends. Because of the above, considerations, how trends are identified will depend not only on the least squares regression method, but will include come judgement by plant personnel on the factors affecting environmentallevels.

MONITORING PROGRAM MONITORING ,I PROGRAM - DISCUSSION, INTERPRETATION AND TRENDING OF I RESULTS I The radionuclides with Technical Specifications reporting levels in the I environmental media samples have been historically trended over an oleven-year period from 1979 - 1990. Analyses from 1977 - 1978 have been excluded since these results were much higher than the other preoperational years due to outside influence such as weapons testing. Including these results l would have produced correlation coefficients and averages that were not representative. The highest annual mean concentration of each Technical , Specification radionuclide from the indicator and control locations for each l I media type was used for the estimation of the mean value and correlation coefficient. The preoperational analyses from 1981 were combined with the operational analyses from the latter part of 1981 and averaged to give one i g concentration for each radionuclide for that year. Ilowever, when L preoperational comparisons were necessary, only the preoperational report was used. Twelve annual means were used to determine trends and often the average concentrations reported were negative. All negative values (concentrations) were replaced with a zero to properly represent I environmental conditions. presentation of the annual mean concentrations for drinking water, Figures 3 through 6 provido a graphical shoreline sediment, fish, and TLD data. Some of these figures show both I indicators and controls for significant radionuclides, while others show only indicators for clarity purposes. These media were chosen for graphical representation for special interest purposes or because they consistently show detectable activity for a few radionuclides. In addition, the percentages of Technical Specifications reporting levels were calculated for each reportable radionuclide in each media type. I Only the radionuclides with Technical Specifications reporting levels were historically trended and compared with the eleven-year average and control levels. It is important to note that while historical trends are helpful in determining radioactivity buildup, environmental radionuclido levels could I be affected without exhibiting increasing or decreasing trends. No Technical Specifications icporting levels were exceeded in 1990 due to plant offluents. Sample analysis reports (SAR'S) are included in Appendix E. On many of I these reports naturally occurring radionuclides (NOR) are listed. In most cases the listed NOR's are potussium-40 (K-40) and Bery111um-7 (Be-7). I I 34

I I 3.2 DRINKING WATER I in 1990, 39 drinking water samples were analyzed for 1-131/LL, 26 at the two indicator locations and 13 at the control location. Tritium (11-3) analyses were performed on 12 composite samples, eight at indicator locations and four at the control location. Thirty-nine samples were analyzed for all the other radionuclides with Technical Specifications l reporting levels, 26 at indicator locations, and 13 at the control location. I Analyses showed zero ranges for allindicator locations which means no detectable activity was measured. All radionuclides did not significantly I differ from the eleven-year average. All radionuclides, except tritium, did not significantly differ from preoperational data. A high to moderate probability of an increasing trend was indicated for I the indicator locations for 11-3. Ilowever, the 1990 11-3 concentration only resulted in 3.66% of the Technical Specifications reporting level. The correlation coefficients indicated a high to moderate probability of l a decreasing trend for Co-60 indicator, Zr-95 indicator, Fe-59 control, I and I-131 (indicator and control) locations. All other radionuclide indicators and controls exhibited moderate to no probabilities of l increasing or decreasing trends. Table 3.2-A and Figure 3 illustrate l these trends.

4 I 3.3 SURFACE WATER 1 I In 1990, 39 surface water samples were analyzed for 1-131/LL, 20 at the two indicator locations and 13 at the control location. Analyses for 11-3 were performed on 12 samples, eight at indleator Ic ations and four at the control location. Thirty-nine samples were a:uu3 :ad for all other E E radionuclides with Technical Specifications reporting levels, 20 at indicator locations and 13 at the control location. All technical specification radionuclides except 11-3 showed zero ranges indicating I that no detectable activity was measured. All radionuclides, except 11-3, were not significantly different from preoperational data and the control location levels. Tritium activity in 1990 showed a decrease from the 1989 I sample results and as all other radionuclides, did not differ signific".ntly from the eleven-year average, There is a moderate to poor probability of an incressing trend for 11-3 i< indicator. There is a high to moderate probability of a decreasing trend for Co-56 (indicator), Co-60 (control) and 1-131 (indicator). The 1990 concentration of it-3 resulted in 3.39% of the Technical Specifications I reporting levels. All other radionuclide indicators and controls exhibited moderate to no probability of increasing or decreasing trends. Table 3.3-A illustrates these trends. I t l l I I I E l 3-11

, 3.4 MILK H In 1990,104 milk samples were analyzed, 78 at the three indicator i locations and 26 at the control location. Mn-54, Co-58, Fe-59, Co-60, 2n-65 Nb-95, Zr-95,1-131, Cs-134, and Ba/La-140 showed a zero range indicating no detectable activity was measured in 1990. The 1-131/LL, Cs-134, Cs-137, and Da/La-140 lI concentrations did not significantly differ from the eleven-year average, preoperational data, and control levels. A high to moderate probability of a decreasing trend was indicated for Cs-137 (indicator) . Six of 78 indicator samples showed detectable activity for Cs-137 in 1990. The 1990 concentration for Cs-137 only I resulted in 7.57% of the Technical Specifications reporting level.

i ? 3.5 BROADLEAF VEGETATION L [ In 1990,48 broadleaf vegetation samples were analyed, 30 at the three indicator locations and 12 at the controllocation. The 1956 data is higher than the other years due to the Chernobyl accident. All technical specification radionuclides except Cs 137 showed zero ranges indicating that no detectable activity was measured. Only two of 30 samples 'I taken indicated Cs-137 activity. The correlation coefficients for the location with the ldghest annual mean I indicated a moderate to poor probability of an increasing trend for Cs-137 indicator and control. Ilowever, this concentration resulted in only 2.01, of the w Technical Specifications reporting level. Since there were anomalous results g in 1984 for Cs-134 and Cs-137, new concentrations for these radionuclides were calculated using the location with the highest annual mean excluding these anomalies. The remaining radionuclide indicators and controls exhibited poor i to no probabilities of increasing or decreasing trends.

f 3.7 FISH in 1990,12 fish samples were anlyzed, six at the indicator locations and six at the control location. All technical specification radionuclides except Co-58, Co-60, and Cs-137 showed zero ranges indicating no detectable activity was measured. The radionuelides named above were not significantly different from the eleven-year average, preoperational data, and controllocation levels. In addition, these concentrations only correspond to small percentages of the Technical Specifications reporting levels as shown in Table 3.7-B. The correlation coefficients for the location with the highest annual mean indicated a moderate to poor [ probability of an increasing trend for the indicator concentrations of Co-58, Co-60, and Cs-137 and a high to moderate probability of a decreasing i trend for the control concentration of Fe-59. All other radionuclide indicators and controls exhibited moderate to no probability of l increasing or decreasing trends. These trends are illustrated in Table B 3.7-A and Figure 5.

] 3.9 FOOD PRODUCTS In 1990, twelve food products (crops) samples were analyzed, all at the l indicator location. No control site was available for food products in 1990. All Technical Specification radionuclides exhibited a zero range indicating no measurable activity present. The 1-131, Cs-137, and Cs-134 concentrations did not significantly differ from the eleven-year average and preoperational data. All of the I radionuclides exhibited moderate to no probability of a decreasing trend. No control sites were available for 1984 through 1990; therefore, a R representative correlation coefficient could not be calculated for the B control data. Table 3.9-A illustrates this summary. No activity was detected and therefore no reporting levels were approached. Table 3.9-B shows the percentages of environmental concentrations to the Technical Specifications reporting levels for the indicators at the location with the highest annual mean for 1990.

E l LAND USE CENSUS RESULTS FOR 1990 I The Annual Land Use Census for McGuire was completed May 18, I 1990. The results of this census are shown on pages 3-30 and 3-31. There were several milk animals and irrigated gardens located in sectors with high D/Q's that were not I used to collect samples for the 1990 Radiological Environmental Monitoring Program. All the respective owners at these locations were questioned to determine if they were interested in providing samples for McGuire's environmental program. Below are the results of this survey.

a SECTION 5. F I QUALITY ASSURANCE l 5.1 DUKE POWER COMPANY'S PRODUCTION ENVIRONMENTAL SERVICES 5.1.1 SAMPLE COLLECTION l The station or other sample collection groups perf orm the environmental sample collections as specified by approved sample collection procedures. I 5.1.2 SAMPLE ANALYSIS l The Radionnalysis Laboratory performs the environmental sample analyses as specified by approved analysis procedures. In 1989, reviewed data indicated detection of Cs-137 in airborne radiciodine cartridges, but not in associated airborne filters for the same sampling period and location. An extensive investigation was conducted in 1990 to determine reasons why low level Cs-137 activity, approximately 1 to 8 picocuries per total cartridge, was being detected on a low percentage basis of all cartridges counted by the Duke Power Radionnalysis Laboratory. The Radioanalysis Laboratory had increased the possibility of detecting low-level activity due to installation of low background shields for gamma spectroscopy. In addition to the new shields employed, analysis techniques in some instances used extended count times. Experimental results determined that the Cs-137 activity was due to the activated carbon media and was present prior to placement into field sampling units. 5-1
I l Various airborne radiciodine cartridges were obtained from different vendors nationwide which had similar characteristics as the cartridges that were in current use by the Duke Power environmental collection team, Findings support that low-level C5-137 is a fallout product that is incorporated into carbon media. It is anticipated that continual observance of low activity Cs-137 will be detected on a random basis in airborne radioiodine cartridges and any trending of this data will be l reported by the Radioanalysis Laboratory to appropriate nuclet.r station personnel for consideration. I 5.1.3 I 00$1 METRY ANALYSIS The Dosimetry Laboratory performs environmental dosimetry measurements as specified by approved dosimetry analysis procedures. I 5.1.4 I INTRALABORATORY QUALITY ASSURANCE The Radioanalysis Laboratory and the Dosimetry Laboratory performed an internal review during 1990 in order to demonstrate an ability and willingness to perform self-audits, and also to aid in performing duties. I The Radioanalysis Laboratory has-an internal quality assurance program which monitors each type of instrumentation for reliability and accuracy. Daily quality control checks ensure 5-2
W that instruments are in proper working order and these checks are used to monitor instrument performance. Additionally, National Institute of Standards and Technology (NIST) standards that represent counting geometries are analyzed as unknowns at various frequencies ranging f rom weekly to annually to verify that efficiency calibrations are velid. The frequency is depehdent upon instrument use and performance. Investigations are performed and docun,)nted should calibration verification data fall out of limits. l 5.1.5 INTERLABORATORY QUALITY ASSURANCE 5.1.5.1 DUKE POWER'S AUDIT DlvlS10N The Radionnalysis Laboratory, Dosimetry Laboratory, and Health and Radiological Projects were participants in a Quality Assurance audit in 1989, performed by Duke Power's Audit Division. Two recommendations were identified in the audit. Actions were taken to enhance laboratory operations based upon the two recommendations. No Quality Assurance Audit was performed in 1990. 5.1.5.2 DUKE POWER'S NUCLEAR PRODUCTION INTERCOMPARISON PROGRAM The Radioanalysis Laboratory participated in the Duke Power Nuclear Production Intercomparison Program during 1990. Unknown body burden standards, marinelli beake s, air filters, air cartridges, gross 53
I alpha / beta on smears, and tritium in water samples are analyzed at various times of the year by the four counting laboratories in Duke Power Company for this program. 5.1.5.3 V.$. NUCLEAR REGULATORY COMMISSION INSPECTIONS The Radioanalysis l.aboratory was audited by the NRC in 1990, No violations, deviations or follow up items were identified by the inspector. Vf b 5.1.5.4 UNITED STATES ENVIRONMENTAL PROTECTION AGENCY INTERCOMPARISON PROGRAM a The Radionnalysis Laboratory participates in the Environmental Protection Agency (EPA) Environmental Monitoring Systems Laboratory Intercomparison Program. The EPA sample types include mixed gamma in water (3 times per year), mixed gamma in milk' (2 times per year), gamma in air filters (2 times per year), iodine in milk (2 times per year), tritium in water (3 times per year), iodine in water (1 time per year), gross alpha / beta in air filters (2 times per year), and gross alpha / beta in water (3 times per year). The Radioanalysis Laboratory subunit prepares and analyzes each sample as quickly as possible and performs and
. documents fC low-up investigations should the data l obtained by the Radioanalysis Laboratory be out of EPA limits. The Radionnalysis Laboratory EPA Intercomparison 5-4
1 l I i Report code is "CP". A summary of the EPA Intercomparison l Reports for 1990 is documented in Table 5.1. Of the ! t'hirty-eight (38) analyses performed in 1990, one analysis (tritium in water cross-check, reference date 2/23/90) was out of EPA acceptance limits. Liquid scintillation vial preparation and analysis was investigated and evaluated in 1990 because of the unacceptable tritium cross-check results. The original results were almost consistently biased high, significantly overestimating the tritium activity of the cross-check, Further investigation of low activity vials such as that of the tritium cross-check and background vials revealed a f requently observed CPM variance of 0.00 to 3.00. This variance appears to have been a key influence affecting the poor performance of the lI l original analysis. lI Additional testing and investigation aimed at reducing the CPM variance mentioned above included:
- 1. Increased dark adaptation time l
I 2. Geometry modification
- 3. Decreased counting times
! These measures have significantly increased sample reproducibility and accuracy .o f results. l investigation and testing have documented that both l
- Beckman liquid scintillation counters and current methodology is acceptable and measures to improve consistency of data as mentioned above have been I

ENVIRONMENTAL MONITORING PROGRAM l The ONS Chemistry Section and Radioanalysis Laboratory routinely participate with the State of South Carolina in their NRC/ State Contract Environmental Monitoring Program, The ONS Chemistry Section splits water, milk, vegetation, sediment, and fish samples with the Bureau of Radiological Health of the State's Department of Health and Environmental Control (DEHC) for analysis. DHEC collects air samples from two of the locations sampled for air by ONS. Results of the analyses performed on split and duplicate samples by the Radicarilysis Laboratory and DHEC Laboratory are compiled by DHEC and provided to the NRC. TLDs are also co-located with the State and NRC at various environmental sites. I 5.1,5.6 NRC/ STATE OF N.C. INTERCOMPARISON PROGRAM g Health and Radiological Projects, Radioanalysis Laboratory, and Dosimetry Laboratory routinely participate with the State of North Carolina Department of Environmental Health and Natural l i Resources (DEHNR) in an intercomparison program. Health and Radiological Projects sends air, water, milk, vegetation, sediment, and fish samples which

I have been collected to the State of North Carolina Radiation Protection Section for intercomparison analysis. TLDs are also co-located with the State and NRC at various environmental sites. Also, every six to eight months, the State of North Carolina Radiation Protection Section irradiatu environmental dosimeters and sends them to the Dosimetry Laboratory for analysis of the unknown estimated delivered exposure. A summary of the State of North Caerlina I Environmental Dosimetry Intercomparison Report for 1990 is documented in Table 5.2. The Dosimetry Laboratory results are within 11% of the State of North Carolina results (excluding Standard Deviation values). 5.1.5.7 U.S. DEPARTHENT OF ENERGY INTERCOMPARISON PROGRAM There was no DOE intercomparison program during calendar year 1990. 5.2 CONTRACTOR LABORATORY No contractor laboratories were used during 1990. 5-7

J APPENDIX A ERYlRQHt1 ENTAL S AM011H2_hMD_ARALYItLS PROCEDURS Adherence to established procedures for sampling and analysis of all environmental media at McGuire was required to ensure compliance to the Station Technical Specifications. Analytical procedures were employed to ensure that Technical Specification detection capabilitias were achieved.
- Envircreental sampling and analyses were perfort.ed by the Duke Power Production Environmental Services Health & hadiological Projects, Radioanalysis Laboratory, Dosimetry Laboratory, end fisheries suounits.
Starting at Appendix A.1, the remainder of this Appendix describes the environmental sampling and analysis procedures by media type. I. QihMGE OF SAMPLING PEDfEQUES The Land Use Census identified an additional food products location at the residence of Elbert Brewer. The Brewer's residence was identified as food prcducts location number 185, and is 4.9 miles from station site in the North sector. Sampling at the Brewer's residence began August 7. 1990. I Surface water sampling location 130 (0.6 mi SW) was moved upstream 0.2 l K miles to the Cowans Ford Dam (0.6 mi W) in August 1986 be c t.use of excessive clogging with the sampling line and pump at the 0.6 mi SW site. The sampling location number is in the process of being changed to 131 to avoid confusion with the location 130 sediment sampling site. II. QltJ1GE OF ANALYSIS PROCEDURES No significant changes to analysis procedutes occurred in 1990. III. SME11HQ_AND ANALYSIjLEEQCEEVEES A.1 h1EBORNE PARTICULATES AND_EhDJ.Q1QD.1HE l Airborne particulate and radioiodine samples at each of five [ locations were composited continuously by means of continuous air samplers. Air particulates were collected on a particulate filter and radioiodines were collected in a charcoal cartridge situated behind the filter in the sampler. Filters and cartridges were collected weekly. A weekly gamma analysis and gross beta analysis was performed on each filter and a weekly gamma analysis was performed on each charcoal cartridge. The filter and cartridge gamma analyses were performed separately. I I A-1

I APPENDIX D MCGUIRE NUCLEAR STATION ANALYTICAL DEVIATIONS I LOWER LIMITS OF DETECTION I Air sampling site #125 charcoci cartridge for collection period 11/27 - 12/4/90 incurred damr:ge upon removal from sample head due to becoming tightly seated during composite period. The charcoal cartridge required prying to loosen it I from sample head, and in process, cartridge integrity was lost, allowing approximately 15% of the charcoal granules to escape. Metal casing of charcoal canister was bent, thereby altering cartridge geometry. l Sample run time and the corresponding air particulate filter were not adversely affected. Sample analysis was performed and all required lower limits of , l detection (LLD) were met within an acceptable counting time. I Sample head of air sampler at location #125 was replaced to alleviate the l recurrence of this problem, I i i I ) I ; I I I I I il I . D-1
