h e INTRODUCTION The 1993 Annual Radiological Environmental Operating Report for Wolf Creek Generating Station (WCGS) covers the period from January 1 though December 31,1993. WCGS is located in Coffey County, Kansas, approximately five miles nortr,-;ast of Burlington, Kansas. Fuel loading commenced at WCGS on March 12,1985. The operational phase of the Radiological Environmental Monitoring Program (REMP) began on May 22,1985 with initial criticality and the first detectable quantities of radioactivity were reported in plar1 effluents in June 1985. This report contains a description of the REMP conducted by Woif Creek Nuclear Operating Corporation (WCNOC), results of sample analyses performed by Teledyne isotopes and WCNOC health physics technicians, a discussion of monitoring program results, a description of revisions to and deviations from the program, and comments on the results of the Environmental Protection Agency (EPA) Interlaboratory Comparison Program. Individual sample results and a summary of results in the Nuclear Regulatory Commission (NRC) Branch Technical Position specified format are included as appendices to the report. No radiological e' feds of plant operations were detected in airbome particulate and radiciodine filters, fish, irrigated crops, breadleaf vegetation, milk, ground water, or drinking water. During 1993, activation products were detected in aquatic plants and algae, shoreline soil, and bottom sediment samples. No measurable impact on human exposure due to plant operation was seen for the year. I I l I 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 1 of 50

1. PROGRAM DESCRIPTION Radiological environmental samples were collected according to the schedule in Section 5.0 and Table 5-1 of the WCGS Offsite Dose Calculation Manual (ODCM). All samples were collected by WCNOC's Environmental Management and Radiological Services groups. The samples were processed and analyzed by Teledyne isotopes of Westwood, New Jersey. Table 1 lists sampling pathways and frequencies of sampling and analysis. Table 2 lists each sample location's distance and direction from the plant. Samples in addition to those required by the WCGS ODCM were obtained in conjunction with the Kansas Department of Health and Environment (KDHE) and to monitor additional parameters.

The following is a description of the sampling and analysk program by individual pathways. Deviations are permitted from the required sampling schedule if specimens are not attainable due to hazardous conditions, seasonable unavailability, malfunction of automatic sampling equipment, and other legitimate reasons. Deviations from the routine sampling schedule and other problems encountered during the year are described in Section IV, Program Deviations. A. Airborne Low volume air sampling pumps continuously collected particulate and radioiodine samples on 47 mm glass fiber filters and charcoal canisters, respectively. Weekly, the filters and charcoal canisters are changed out, labeled, and then shipped to Teledyne Isotopes for analysis. The volume of air sampled was calculated from the average of initial and final flow rates and the total time of collection. Each pump is equipped with a time totalizer that is checked weekly against the elapsed time. Gross beta analysis of the air particulate samples were performed approximately 72 hours post collection to allow the radon and thoron daughter products to decay. Each filter was mounted on a stainless steel planchette and counted on an automatic alpha-beta counter. Weekly air particulate filters were combined into quarterly composites for each location and analyzed for gamma emitting isotopes on a Ge(Li) detector. Charcoal canisters were routinely counted in groups of five to determine the presence or absence of I-131. Positive indication of I-131 would have resulted in analysis of each individual charcoal canister. Air samples were collected from the three sectors with the highest ground level deposition constants (D/Q), the community of New Strawn, and a control location. Distances and directions to sampling locations from the plant site are listed in Table 2; locations are shown in Figure 1 (nearby locations) and Figure 5 (distant locations). B. Direct Radiation One type of thermoluminescent dosimeters (TLDs) used during 1993 were provided by Teledyne isotopes. The TLDs consisted of rectangular Teflon wafers impregnated with CaSO4:Dy. Prior to placement in the field, the dosimeters were annealed for at least one hour at 250 to 260 degrees Centigrade. The TLDs are then placed in polyethylene pouches and holders containing 0.093 inch thick copper shields to filter out low energy radiation. Freshly annealed dosimeters were exchanged with exposed dosimeters and the exposed dosimeters are shipped to Teledyne isotopes for analysis. Four freshly annealed TLDs are shipped as controls with the exposed TLDs to record any exposure received in transit. 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 2 of 50

) Gamma exposures are measured on a Teledyne Model 8300 TLD reader. Individual dosimeters are then exposed to a Cs-137 source to determine each dosimeter's calibration factor. Panasonic UD-814-AQ TLDs were also used during the third and fourth quarters of 1993. These TLDs consist of one lithium-borate element and three calcium sulfate elements in a plastic case. Each TLD is annealed and analyzed by Wolf Creek health physics technicians on a Panasonic UD-710A TLD reader. In general, TLDs are positioned roughly 3 to 4 feet above the ground on utility poles. They are contained in either plastic thermostat boxes or f3erglass air sample pump housings. The boxes and housings protect them from the elements and tampering. Two TLDs are placed at each designated location. TLD sample locations are illustrated in Figure 2 (nearby locations) and Figure 5 (distant locations). Table 2 provides the distance and direction of each location from the site. C. Waterborne All water samples are analyzed for gamma emitters on a Ge(Li) detector. Radiochemical analysis for 1-131 is performed on drinking water and ground water samples. Gross beta analysis is performed on drinking water samples. Tritium analysis is performed by liquid scintillation monthly for surface water and quarterly for drinking water. Tritium analysis is performed by gas proportional counter quarterly for ground water. All water sampling locationsare listed in Table 2 and shown in Figures 3 and 5. Drinking water is sampled at the water treatment facilities for the towns of Burlington and Leroy. The Burlington facility is located upstream and the Leroy facility is located downstream of the confluence of the effluent from Wolf Creek Cooling Lake (WCCL) and the Neosho River. Monthly, composite samples are obtained from automatic composite samplers at each location that draw approximately 10 ml samples hourly. Monthly, grab samples are drawn from each surface water location. Surface water is sampled at the outfall of John Redmond Reservoir (JRR) as a control and in the discharge cove and spillway of WCCL for indicator locations. Ground water samples are collected quarterly from four locations. One ground water well is hydrologically upgradient from the site (location B-12) and is used as a control location. Three additional samples (C-10, C-49, and D-65) are obtained from wells hydrologically downgradient from the site as indicator samples. Shoreline sediments are sampled semiannually for gamma analysis at the discharge cove (indicator, Figure 3) and at JRR (control, Figure 3). Bottom sediments are also collected semiannually. Samples are obtained for gamma analysis at the discharge cove (indicator, Figure 3) and at JRR (control, Figure 3). In addition, a sample was obtained in the area of the ultimate heat sink (UHS, Figure 3) Semiannual aquatic plant and algae samples are obtained for gamma analysis from the discharge cove area or from an attemate location near the discharge cove (DC and DC ALT, respectively on j Figure 3). 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 3 of 50

i l D. Ingestion Milk samples are collected semimonthly from April through November (while the animals are feeding on pasture grass) and monthly from December through March (while the animals are on stored feed). No sampling locations were identified within 5 miles of the plant that produced milk for human consumption during 1993. Therefore, only control samples were obtained. Radiochemical l-131 and gamma isotopic analyses were performed on each sample. The control location is illustrated on Figure 5. 1 Broadleaf vegetation samples were collected monthly during the growing season from four gardens. The three indicator gardens (two regular and one alternate) and a control garden were sampled (Figure 5). Gamma isotopic analysis was performed on all samples. Irrigated crops (soybeans and corn) were also sampled. Two samples were obtained from cropland downstream of the confluence of WCCL effluents and the Neosho River gadicator) and one sample was obtained upstream (control). However, due to high rainfall amounts in the region during 1993, no irrigation from the Neosho River occurred during 1993. The samples were still obtained to serve as baseline data and to continue contact with local landowners. Gamma isotopic analysis was performed on each sample. Fish are sampled from the tail waters of JRR (control) and from WCCL semiannually for gamma isotopic analysis (Figure 4). Several recreationally important species and rough species are sampled. Gamma isotopic analysis is performed on boneless meat portions of the fish. [ Game animals and fowl are sampled annually in the immediate vicinity of the plant and at a control l i locc.on that is remote from the site. Gamma isotopic analysis is performed on boneless meat portions of the game. All sampling locations listed in this section are outlined in Table 2. l l l l 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 4 of 50 e-

II. DISCUSSION OF RESULTS Analysis results for all pathways are summarized in Appendix A using the format described in NRC J Radiological Assessment Branch Technical Position, Revision 1, November 1979. Results for l individual samples are listed in Appendix B. i In this section, results are discussed by pathway and analysis type. Operational results are related to j controls, preoperational data, sources of radioactivity, and effluent releases when applicable. Trends or seasonal effects are discussed. Tables 3 through 16 illustrate results of interest for 1993. Associated errors for positive results may be obtained in Appendix B. A. Airborne 1 Results of the weekly gross beta analysis are summarized in Table 3. Figure 6 illustrates a plot of weekly gross beta results for 1993. Figure 8 illustrates a historical plot of the gross beta 1/C ratios and includes a smoothed average trend. Although the smoothed average has a very slight increasing trend, the gross beta values for the time period are consistent with expected background and suggest that the slightly increasing 1/C ratios are a result of changing environmental conditions. For instance, Figure 7 illustrates a slightly decreasing trend for location 40 (airbome sample control location) since 1989. Decreasing control values would tend to increase the I/C ratio over time. In addition, no radiciodine has been detected since 1989. Therefore, the slight increase in gross beta l/C ratios is due to a slight decrease in control location gross beta values over time and is not due to plant operations. It is also interesting to note that the smoothed plot (Figure 7) shows a definite seasonal cyclic trend in which gross beta values peak in the winter months (December or January) and decrease to a low point in the spring months (May or June). Figure 9 illustrates a historical plot of average weekly indicator and control gross beta values during plant operations. l Table 4 summarizes the gamma analyses of 1993 airborne particulate filter quarterly composites. The table shows that only natural radioisotopes Be-7 and K-40 were detected. No effects of plant operation were seen via air samples during 1993. B. Direct Radiation 1993 quarterly gamma exposures for each location are summarized in Tables 5 and 6. Values are normalized to a standard 90 day quarter. Figure 10 shows the nearsite TLD data expressed as a percentage of the control data. Results from TLDs located near the plant site (<3 miles distant) have been combined into quarterly averages. Note that nearsite TLD locations have historically trended higher than the control locations both prior to and after WCGS became operational. Figure 11 showa the historical quarterly average values expressed in mrem /std 90 day quarter for both nearsite and control locations Figure 11 also shows that the levels of direct radiation measured by thermoluminescent dosimeters near Wolf Creek have declined from 1980 to 1993. This decrease in measured radiation levels is suspected to be caused by a decline in TLD efficiency. Linaar regression analyses of the direct radiation levels expressed as averages for a standard 90-day quarter indicate that measured radiation levels have declined significantly at indicator locations (p is less than or equal to 0.05 and r-squared is 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 5 of 50

8 equal to 0.49) and at control locations (p is less than or equal to 0.05 and r-squared is equal to 0.45). This decrease in measured direct radiation levels is not believed to be caused by a decrease in environmental direct radiation levels because Kansas Department of Health and Environment direct radiation results for locations near Wolf Creek do not show a similar decrease in measured direct radiation levels (internal KDHE data). Despite the decline in direct radiation levels measured by Wolf Creek's TLDs, a comparison of indicator and control location results still indicates that the direct radiation levels are not related to plant operation As also shown in Figure 11, the ratio of the near-site indicator location results to the control location results has remained near 100 percent through 1993. The near-site indicator location results and the control location results exhibited significant correlation (p is less than or equal to 0.05 and R is equal to 0.93) and this indicates that fluctuations in direct radiation levels were measured with a high degree of certainty by both the indicator and controllocation TLDs. However, if measured direct radiation levels continue to decline, the TLD results will tall below the range of pre-operational averages for Wolf Creek and the range of direct radiation levels measured by the NRC (note 1) and KDHE (note 2). Panasonic UD-814-AQ TLDs were placed in the same locations as the Teledyne isotopes TLDs during the third and fourth quarters of 1993 as a cross-comparison measure and the Teledyne TLDs will be replaced with the Panasonic TLDs during 1994. Please note that the supplemental Panasonic TLD data were used for the third quarter of 1993 on Figure 11 because the third quarter Teledyne TLDs could not be accurately analyzed. Please refer to the program deviations section for more information about the third quarter TLDs. Notes:

C. Waterborne (1) Drinking Water Results of drinking water gamma isotopic analyses are summarized in Table 7. No tritium was detected in drinking water samples during 1993. Figure 14 illustrates the historical drinking water gross beta data through 1993. The comr site samples for May 4 through June 1 and August 3 through August 31 exhibited elevated gross beta results, especially in the duplicate sample results for indicator location LW-40 on both June 1 and August 31. The indicator and control location both displayed elevated values for June 1, which suggests that the elevated values are not related to plant operations. Comparing the error range for the indicator location gross beta results on June 1 and August 31 shows that the i.iitial results are within the error range of the duplicate results. No other nuclides were identified during 1993. No activity due to plant operations were evident in drinking water samples during 1993. 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 6 of 50

) 4 (2) Surface Water Surface water data is summarized in Table 8. Tritium was the only nuclide identified in surface water samples during 1993. Figure 12 illustrates smoothed tritium data for WCCL from startup in May 1985 through 1993 for locations DC and SP and the cumulatise curies of tritium released to WCCL. Tritium values have been declining recently and the declining trend may be due to high precipitation during 1993. Significant discharge from WCCL occurred during 1993 as a result of precipitation. The increased precipitation allowed some dilution or replacement (with nontritiated water) of the tritiated water inventory in WCCL. The region had experienced a prolonged drought during the previous 2 to 3 years. Little discharge from WCCL occurred during the dry period. Note that the tritium levels are well below the 20,000 pCi/ liter reporting limit for drinking water sources and the 30,000 pCi/ liter limit for other water sources. Figure 13 illustrates the same smoothed tritium data for WCCL exwpt quarterly tritium effluent discharges are plotted. (3) Ground Water No gamma emitters or tritium were detected in ground water samples during 1993. A summary of results is included in Table 9. (4) Shoreline Sediment Naturally occurring nuclides Ra-226, Th-228, and K-40 were detected in shoreline sediment samples during 1993. Co-60 and Cs-137 were detected in samples obtained from the discharge cove (DC) and Cs-137 was also detected in a control location sample collected from JRR. The Co-60 activity is attributable to plant operations but the Cs-137 activity is likely the result of increased atmospheric fallout. The levels of Cs-137 activity detected in the discharge cove and control location samples exceed the range of Cs-137 fallout measured during pre-operational studies (0.0131 to 0.0478 pCi/L). No Cs-134 was detected in the shoreline sediment samples, as would be expected if the source of the Cs-137 activity was plant operations. Cs-134 has a half-life of 2.05 years and it would be expected to be detected in a sample collected close to a source of both Cs-134 and Cs-137. Neither Cs-137 or Cs-134 were detected in monthly surface water samples collected at the discharge cove or JRR during 1993. Analysis results are summarized in Table 11. D. Ingestion (1) Milk No indicator locations for milk were available for sampling during 1993 (see Program Deviation section for explanation). A control sample was routinely obtained for analysis. All milk samples analyzed contained K-40 at levels consistent with preoperational data. The yearly average K-40 concentration was 1340 pCi/ liter. Table 15 summarizes milk analysis results for 1993. No other gamma emitters were detected. (2) Food and Garden Crops Gamma analyses of broadleaf vegetation samples during 1993 revealed naturally occurring gamma emitters K-40 and Be-7 at concentration consistent with preoperatiorial levels. Another naturally-occurring isotope, Th-228, was detected in one broadleaf vegetation sample during 1993 at 0.0606 pCi/ gram. Broadleaf vegetation results are summarized in Table 13. 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 7 of 50

h c No additional gamma emitters were detected in broadleaf vegetation samples during the remainder of the year. Crop samples were obtained from lands normally irrigated by the Neosho River below the outfall of WCCL. However, due to adequate precipitation during 1993, no irrigation was needed. The samples were still obtained to continue Wolf Creek's relationship with local landowners and to continue to establish baseline values. Results of crop analyses are summarized in Table 14. No nuclides attributable to plant operations were detected. (3) Fish Analysis results are illustrated in Table 16. Naturally occurring K-40 was detected in all fish samples with an average concentration of 3.33 pCi/ gram (wet weight). Th-228 was also detected in all fish samples. No other radionuclides were detected in fish during the year. E. Special Samples (not required by the WCGS ODCM) (1) Game Animals and Birds Naturally occurring K-40 was detected in all game animal and bird samples in concentrations consistent with preoperational levels. No other radionuclides were detected and no effects of plant operations were detected in this pathway. j (2) Bottom Sediment Table 12 shows gamma emitters detected during 1993 in bottom sediment samples. Sampling locations include the Ultimate Heat Sink (UHS), DC, and JRR. Natural nuclides detected include K-40, Ra-226, and Th-228. Several other nuclides were detected in bottom sediment samples. A portion of the Cs-137 activity detected in WCCL bottom sediments is probably attributable to fallout and a portion is due to plant operation The Cs-137 levels are only slightly higher than those reported prior to WCGS criticality and therr. ce a major portion of the activity is due to fallout. However, the Mn-54 and Co-60 activity shown in ie table are attributed to plant operations and are regularly identified in plant effluents. Be-7 was detected in one of five supplemer.tal samples collected in the discharge cove during 1993 as an attempt to determine the variation of activity levels in the discharge cove. The activity levels detected at the supplemental sample locations were consistent with the levels detected at location DC. (3) Aquatic Vegetation Table 10 shows gamma emitters detected during 1993 in aquatic plant samples. Be-7, K-40 and Ra-226 were detected in all samples collected. Th-228 was detected in one sample. An alga sample accumulated the most detectable activity. Mn-54, Co-58, Co-60, Cs-134, and Cs-137 were all detected in at least the alga sample and some were detected in the other aquatic plant samples as well. 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 8 of 50

.h s i j IIL ANNUAL LAND USE CENSUS RESULTS AND PROGRAM REVISIONS Section 5.2 of the WCGS ODCM directs that "A Land Use Census shall be conducted annually during the growing season to identify the nearest (1) milk animal, (2) residence, and (3) garden of greater that 500 square feet producing broadleaf vegetation in each of 16 meteorological sectors within five miles of the WCGS Site." The results shall also be included in the Annual Radiological Environmental { Operating Report. Table 5-1 of the WCGS ODCM states that garden (broadleaf) sampling locations will be "from two indicator locations with highest calculated annual average D/Q". Methodology The 1993 Land Use Survey was completed in October. Information was collected using a i combination of mailed survey forms, telephone contacts, and door-to-door contacts. 1 } Surveys were mailed to the rural residences within five rniles of WCGS during the second week of l August 1993. - The survey excludes the residents of New Strawn, Burlington, and a trailer park just ] north of Burlington. These locations are excluded because of the large number of households and the low probability that information gained from these residences would affect the locations used for REMP sampling. A total of 137 surveys were mailed to rural locations, and 115 responses (83.9 l percent) were received or obtained by Wolf Creek personnel. Response rates for the last six years range from 85 to 90 percent. \\ 4 l Results 1 The total population for the responding residences was 373 persons for an average of 2.63 persons ) per household. This average and the 137 known occupied residences are used to estimate the total rural population within five miles of the site (excluding New Strawn, Burlington, and the trailer park). i ' The rural population is estimated at 384 persons. The population estimates were 466 in 1991 and 500 in 1992. The drop in rural population for 1993 is attributed to the change in survey methodology described above but not to an actual reduction in population. Results are summarized in Tables 17 i l and 18. No milk animals that produced milk for human consumption were identifiec' within 5 miles of WCGS 7 again in 1993. i i Summay 1 On the basis of the data collected in the 1993 Land Use Census, no changes are required in the REMP. ) i a i i 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 9 of 50 l

A IV. PRODRAM DEVIATIONS Airborne Location 37,8/3/93 to 8/10/93: No airborne particulate or radiciodine samples were collected from location 37 during this week because the air sample pump switch did not completely engage when the pump was turned on after changing sample filters on 8-3-03. The switch apparently turned the pump off as the pump fuse was not blown. The switch was checked and the pump functioned properly after it was restored to service. Location 32,8/10/93 to 8/17/93: No airbome particulates were collected during this week at location 32 because the particulate filter was not properly seated in the sample head. A small gap allowed air to be drawn around, rather than through, the filter. The sample head was examined for mechanical defects and none were found. The particulate filter was replaced and the pump returned to service. Air particulate gross beta results from the other four WCNOC sampling locations for this week are consistent with historical air particulate gross beta levels, as are the air particulate gross beta results for location 32 from the week of 8/17/93 to 8/24/93. These results indicate that the sampling equipment functioned properly when retumed to service. Drinking Water Location LW-40, 4-25-93 to 4-26-93: Approximately 210 milliliters of the 7,200 milliliter monthly composite sample were not collected on these days because the sample collector blew its fuse after routine maintenance was performed on 4-25-93. The tubing used to replace the tubing in the pump roller housing was too stiff for the pump motor to turn the roller easily. The resistance of the stiffer tubing caused the motor to blow the fuse. The sampler with the improper tubing was replaced with a back-up sampler and composite sampling mMinued. The water sampler maintenance procedure was revised to specify and require that only the sampler manufacturer's replacement tubing be used. The loss of the 210 millimeters of drinking water did not significantly affect the drinking water analysis results for April 1993 and the composite sampler functioned properly during May and June of 1993. Location BW-15, October 1993: The drinking water sample for October was not collected at Burlington because the tube from the sample pump to the collection container was not connected properly after the September sample was collected. An extra tubing connection was removed on 11-2-93 to prevent future mistakes of this type. The November sample was properly collected. Location LW-40, October 1993: The tube from the sample pump to the collection container was not connected properly after the September sample was collected and the sample was pumped into the sample container housn,g, instead of the sample container. One gallon of drinking water was collected from the container housing and the analysis results were consistent with results from previous months. An extra tubing connection was removed on 11-2-93 to prevent future mistakes of this type. The November sample was properly collected. Location BW-15, December 1993: The composite sampler was damaged during December and collected only half its normal monthly volume. The sampler case had been cracked and the electronic components interrupted the composite sampling program. Damage to the sampler was detected on 1-4-94 and the broken sampler replaced on 1-5-94. The replacement sampler functioned properly. 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 10 of 50

} o Direct Radiation Samplers (TLDs) All Locations, Second Quarter 1993: TLDs were collected from all sampling locations as required. Even though the shipping container was clearly marked "DO NOT X-RAY", the shipping container was inadvertently x-rayed before leaving WCGS. The TLDs were shipped to Teledyne Isotopes and analyzed as per normal protocol. Four freshly annealed TLDs were included in the shipping package as per procedure to record transit exposure. The TLD results showed no adverse consequences due to the x-ray exposure and no abnormal readings resulted. The TLDs included to record transit exposure yielded exposures similar to what is normally experienced during shipment. Location 9, Second Quarter 1993: The TLD housing cover was missing and thus the TLDs had been j exposed to the elements prior to collection. The cover was replaced after the TLDs were collected. j No abnormal readings resulted. ] Location 16, Second Quarter 1993: The tree to which the TLDs and protective housing were affixed was struck by lightning sometime during the second quarter. The TLD housing cover was missing and thus the TLDs had been exposed to the elements prior to collection. The cover was replaced after the TLDs were collected. No abnormal readings resulted. J Location 29, Second Quarter 1993: The TLD housing cover was missing and thus the TLDs had been exposed to the elements prior to collection. The cover was replaced after the TLDs were collected. No abnormal readings resulted. All Locations, Third Quarter,1993: Abnormal and unusable results were produced when the third quarter TLDs were analyzed by Teledyne isotopes. Some locations has negative results while other results varied widely between locations and the transit dosimeters used to detect any dose absorbed during shipment indicated abnormally high exposures of 42.1 millirems to 56.3 millirems. Normal i transit TLD dose readings are three to five millirems. It appears as if the TLDs received significant dose from an unknown source during shipment but that could not be confirmed by Federal Express. In 1994, WCNOC will replace the Teledyne TLDs with Panasonic TLDs that can be analyzed on site, i which will reduce the potential of receiving abnormal transit dose. Location 5, Fourth Quarter 1993: The TLD housing cover was missing and thus the TLDs had been exposed to the elements prior to collection. The cover was replaced after the TLDs were collected. i No abnormal meings resulted. Ingestion Milk There were no deviations in milk sampling. However, there are still no indicator sampling locations available within five miles of the plant.

b V. EPA INTERLABORATORY COMPARISON RESULTS Teledyne isotopes is contracted to perform radiological analysis of environmental samples for WCNOC.. Teledyne participated in the EPA Interlaboratory Comparison Program during 1993.

i Table 19 shows intertaboratory comparison test results received during the year. The table lists the sample date, the sample media, the nuclide or analysis type, the known value reportod by the EPA, the measured value reported by Teledyne Isotopes (based upon triplicate analysis), and the normalized deviation from the known. Results are listed in the table for sample media and analysis types corresponding to those performed for WCNOC. Except for one measurement, all of the Teledyne isotopes results were within three standard deviations of the known EPA results. Only results exceeding three standard deviations require corrective action. In the case of the one exception, an investigation was performed as described in footnote (e) of Table 19. Three results were betweer, two and three standard deviations. Those three required investigation. The footnotes of Table 19 describe the results of the investigations. l 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 13 of 50

Units are pCi/ liter for water and milk except K j l 1s in mg/ liter. Units are total pCi for air particulate filters. 1 (b) Teledyne Results - Average one sigma. Units are pC1/ liter for water and milk except K is in mg/ liter. Units are total pC1 for air particulate filters. (c) Normalized deviation from the known. (d) By oversight, we did not use the special self-absorption curve which we had previously derived using EPA water and Cs-137 standard. We will use the EPA curve in the future. We may also re-derive this cun e using a water sample which the EPA has agreed to send us. (e) The calculations were checked and found to be correct. The results of six gamma emitting isotopes were reported to the EPA. The results of four were within 1 normalized deviation; a fifth, within 2 l normalized deviations. Only the Zn-65 average was outside the controllimits. There is no obvious l reason why one isotope should be outside the control limits, while five other isotopes were within control limits. ' (f) An investigation is being conducted; the results will be available shortly. l 1993 Annual Radiological Environmental Operating Report Wolf Creek Generating Station Page 36 of 50
