Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station Summary The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for Waterford 3's (W3) Radiological Environmental Monitoring Program (REMP) for the period January 1 through December 31, 2001. This report fulfills the requirements of W3 Technical Specification 6.9.1.7.

During 2001, gross beta radioactivity was detected in all air and drinking water/surface water locations. Results obtained at the indicator locations were similar to those obtained at the control location. Therefore, levels continue to remain at background.

Cesium-137, a man-made nuclide, was detected once during 2001 at an indicator sediment location (SHWE-3). This is consistent with results obtained from the preoperational program and previous years of operation. Studies in Louisiana indicate that Cesium-137 is commonly found in soils and sediments as a result of atmospheric weapons testing. Because the Cesium-137 levels are consistent with preoperational values, the Cesium-137 level detected in 2001 is more than likely attributable to weapons testing fallout.

Even though tritium was detected in three groundwater samples, the values observed were less than the required LLD in all three samples. Tritium is routinely released as measured in effluent sampling analysis via this pathway. Those levels observed are consistent with effluent sampling and analysis results.

Radiological Environmental Monitoring Program W3 established the REMP prior to the station becoming operational (1985) to provide data on background radiation and radioactivity normally present in the area. W3 has continued to monitor the environment by sampling air, water, sediment, milk, fish and broadleaf vegetation, as well as measuring radiation directly.

The REMP includes sampling indicator and control locations within a 50-mile radius of the plant. The REMP utilizes indicator locations near the site to show any increases or buildup of radioactivity that might occur due to station operation, and control locations farther away from the site to indicate the presence of only naturally occurring radioactivity. W3 compares indicator results with control, preoperational, and previous years operational results to assess any impact W3 might have on the surrounding environment.

In 2001, W3 collected environmental samples for radiological analysis. Based on the comparison results of indicator locations with control locations and previous studies, it was concluded that overall W3 operations had no significant impact on plant environs with the exception of groundwater tritium where a direct correlation from plant operations exists well below the reporting level. The review of 2001 data, in many cases, showed undetectable radiation levels in the environment and near background level in significant pathways associated with W3.

Harmful Effects or Irreversible Damage The REMP did not detect any harmful effects or evidence of irreversible damage in 2001. Therefore, no analysis or planned course of action to alleviate problems was necessary.

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station Reporting Levels W3's review indicates that no samples equaled or exceeded reporting levels for radioactivity concentration in environmental samples, as outlined in Technical Requirements Manual (TRM)

Table 3.12-2 when averaged over any calendar quarter, due to W3 effluents. Therefore, 2001 results did not trigger any Radiological Monitoring Program Special Reports.

Radioactivitv Not Attributable to W3 The W3 REMP detected radioactivity attributable to other sources twice. These include the 25th Chinese nuclear test explosion in 1980, and the radioactivity plume release due to reactor core degradation at the Chernobyl Nuclear Power Plant in 1986.

Comparison to State Program W3 compared REMP data to the monitoring program of the Environmental Radiological Laboratory Department of Environmental Quality Laboratory Services Division (ERL-DEQLSD). The ERL-DEQLSD and the W3 REMP entail similar radiological environmental monitoring program requirements. Both programs have obtained similar results over previous years.

Sample Deviations

• Milk Samples Two milk samples were unavailable from indicator location MKQ-5 due to cows not producing enough milk. Milk samples were not available during the 2001 reporting period from location MKQ-1 since the cows are not currently producing milk for human consumption. With the absence of milk samples at these locations, broadleaf vegetation sampling was performed as required by TRM Table 3.12-1.

+ Air Samples The air sample locations listed below failed to meet the requirement for sample continuity.

However, required LLDs were achieved in all cases. As described in footnote (1) of TRM Table 3.12-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons.

• Water Samples The drinking/surface water sample locations listed below failed to meet the requirement for sample continuity. However, required LLDs were achieved in all cases. As described in footnote (1) of TRM Table 3.12-1, deviations are permitted from the required sampling schedule due to malfunction of sampling equipment and other legitimate reasons.

Location Sample period Explanation of Deviation DWP-7 09/10/01 - 10/08/01 Calibration check unsatisfactory DWE-5 09/10/01 - 10/08/01 Low battery

+ TLDs Station K-1 was missing one TLD during the third quarter monthly inspection. The remaining TLD was left in place and read at the end of the quarter.

• Missed Samples TLD station D-2 was missing during the fourth quarter monthly inspection due to vandalism.

Another set of TLDs was placed at this location on 11-13-01.

• Required Lower Limit of Detection (LLD) Values All LLDs during this reporting period were within the acceptable limits required by the W3 TRM.

• Unavailable Results W3 received analytical results in adequate time for inclusion in this report. In addition, W3's review identified no missing results.

Program Modifications W3 made no modifications to the REMP during 2001. However, some modifications were made early in 2002. In February, 2002, REMP sample locations were cited using GPS coordinates and geological mapping software while revising the Offsite Dose Calculation Manual. As a result of this study, several discrepancies were noted with respect to sample locations including the following:

S TLD location R-1 was actually located in sector Q.

0 TLD location H-6 was actually located in sector G.

S TLD location G-9 was actually located in sector F at a distance of 8 miles.

S Air Sample location APG-1 was actually in sector F.

S Drinking/Surface water location DWG/SWG-2 was actually in sector F.

3

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station As a result of these descrepancies, the following changes were implemented in Revision 7 of the ODCM in March 2002:

• TLD location R-1 was moved a short distance to a location actually in sector R.

• TLD location H-6 was relocated to sector H eight miles from the plant because there was not a suitable location in sector H within the 6-8 km distance specified in Table 3.12-1 of the Technical Requirements Manual (TRM).

• TLD location G-9 was moved a short distance to a location actually in sector G, and the designation was changed to G-8.

• Air Sample location APG-1 was renamed to APF-1 and a verification of appropriate sector citing in accordance with the requirements of Table 3.12-1 of the TRM was performed.

• Drinking/Surface water location DWG/SWG-2 was renamed to DWF/SWF-2.

The following additional changes to the REMP were also incorporated in Revision 7 of the ODCM:

"* Sample location descriptions were modified to include GPS coordinates, bearing, and distance.

"* A control Shoreline Sediment sample (SHWQ-6) was added as a result of a requirement change to TRM Table 3.12-1 under DRN 02-357 which added an upstream requirement due to Entergy Nuclear - South REMP standardization.

"* Shoreline Sediment frequency was changed from Semi-Annually to Annually as a result of a requirement change to TRM Table 3.12-1 under DRN 02-357 due to Entergy Nuclear - South REMP standardization.

"* Broad Leaf and Milk collection frequency was changed from Monthly to Quarterly as a result of a requirement change to TRM Table 3.12-1 under DRN 02-357 due to Entergy Nuclear South REMP standardization.

"* Deleted Broad Leaf control location BLK-1 5 because this location was replaced with BLE-20 which meets the TRM Table 3.12-1 directional requirements and has been shown to provide sufficient vegetation throughout the year.

"* Reclassified GWK-1 as Surface Water and installed a composite sampler at this location as required for surface water sampling. Ground Water sampling is no longer performed.

• Deleted Milk location MKQ-1 because this location no longer provides milk.

• Added a new fish location, FH-3, because fish can conceivably be affected by plant discharges via the 40 Arpent Canal discharge pathway.

A copy of the affected ODCM Tables are included in this report in Attachment 3.

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station 1.0 Introduction 1.1 Radiological Environmental Monitoring Program W3 established the REMP to ensure that plant operating controls properly function to minimize any associated radiation endangerment to human health or the environment. The REMP is designed for:

"* Analyzing important pathways for anticipated types and quantities of radionuclides released into the environment.

"* Considering the possibility of a buildup of long-lived radionuclides in the environment and identifying physical and biological accumulations that may contribute to human exposures.

"* Considering the potential radiation exposure to plant and animal life in the environment surrounding W3.

"* Correlating levels of radiation and radioactivity in the environment with radioactive releases from station operation.

1.2 Pathways Monitored The airborne, direct radiation, waterborne and ingestion pathways, as seen in Figure 1-1, are monitored as required by W3 TRM Table 3.12-1. A description of the W3 REMP utilized to monitor the exposure pathways is described in Table 1.1 and shown in Figures 1-1, 1-2 and 1-3.

Section 2.0 of this report provides a discussion of 2001 sampling results with Section 3.0 providing a summary of results for the monitored exposure pathways.

1.3 Land Use Census W3 conducts a land use census biannually, as required by Section 3.12.2 of the TRM. The purpose of this census is to identify changes in uses of land within five miles of W3 that would require modifications to the REMP and the Offsite Dose Calculation Manual (ODCM). The most important criteria during this census is to determine the location in each sector of the nearest:

1) Residence

2) Animal milked for human consumption

3) Garden of greater than 50 m2 (500 ft2 ) producing broadleaf vegetation.

W3 conducts the land use census by:

" Field surveys in each meteorological sector out to five miles in order to confirm:

Nearest permanent residence

> Nearest garden and approximate size

> Nearest beef cow

> Nearest food product

> Nearest milking animal.

"* Identifying locations on maps, measuring distances to W3 and recording results on data sheets.

"* Comparing current census results to previous results.

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station 2.0 Interpretation and Trends of Results 2.1 Air Particulate and Radioiodine Sample Results Samples of airborne particulate and radioiodine were collected at four indicator locations and one control location and analyzed for gross beta radionuclides, Iodine-131 and gamma radionuclides (quarterly air particulate filter composites only). W3 did not detect any gamma radionuclides in the quarterly air particulate composites or Iodine-131 in the radioiodine cartridges during the reporting period, as has been the case in previous years. Indicator gross beta air particulate results for 2001 were similar to those background levels obtained in previous years of the operational REMP and well below preoperational levels as seen below.

Results are reported as annual average pCi/m 3 .

Monitoring Period Result Preoperational 0.080 1983 -2000 0.019 2001 0.020 Table 3.1, which includes gross beta concentrations for 2001 and provides a comparison of the indicator and control means, further emphasizes that the airborne pathway continues to remain at background levels. In addition, as shown in Attachment 2, the standard "t" test was used to compare average gross beta activity from each indicator station to the average gross beta activity at the control station. The results from this test show the average activity detected at all indicator stations is statistically the same as the average activity detected at the control station. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2001.

2.2 Thermoluminescent Dosimetry Sample Results The average exposure rates during 2001 are consistent with those from the preoperational program and the previous five years of operation as seen in Figure 2-1. In particular, the preoperational survey indicates that exposure rates ranged between 11 and 33 mrem/standard quarter with an average of 20 mrem/standard quarter. The range during the previous five years of operation was 9 to 16 mrem/standard quarter with an average exposure rate of 13 mrem/standard quarter.

A comparison of the indicator results to the control results, as seen in Table 3.1, shows that the average indicator is slightly higher than that of the control. As shown in Attachment 1, Table 2.1, several indicator locations are higher than the control by a few mrem with a maximum difference of six mrem on one occasion (G-2, 4th Qtr).

As shown in Attachment 2, Table 2.1, the standard "t" test was used to compare average exposure rates for TLD stations located in groups 0-2 miles and 2-5 miles from the plant to those >5 miles. The results indicate that the average exposure rates 0-2 miles from the plant are statistically the same as >5 miles while those 2-5 miles are statistically higher.

The differences between indicator locations and the control, and TLD stations grouped by distance from the plant are expected due to a variety of factors not related to W3 plant operations that can affect background radiation in the vicinity of each TLD station. Direct radiation measurements at each TLD station have remained statistically the same in 2001 as previous years of operation as evidenced on Attachment 2, Table 2.2. In addition, Radiological Gaseous Effluents for 2001 were only a small fraction of the limits as is typical in previous years of operation and are not expected to have any impact on environmental TLD measurements.

21

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station 2.3 Water Sample Results Analytical results for 2001 drinking/surface water and groundwater samples were similar to those reported in previous years.

Drinking/Surface Water Drinking water samples also serve as surface water samples for W3. Therefore, monthly and quarterly gamma spectroscopy and tritium analyses of drinking water also satisfy the surface water sampling requirement.

Composite drinking/surface water samples were collected from two indicator and one control location and analyzed for Iodine-131, gamma radionuclides and tritium. Results indicate that all measurements were below the calculated LLDs.

Although gross beta was detected in the drinking/surface water samples, results for the indicator locations are similar to previous operational and preoperational years as seen below.

Results are reported as annual average pCi/I.

Monitoring Period Result Preoperational 7.0 1983 -2000 5.3 2001 4.5 Table 3.1, which includes gross beta concentrations for 2001 and provides a comparison of the indicator and control means, shows that the waterborne pathway continues to remain at background levels. In addition, as shown in Attachment 2, the standard "t" test was used to compare average gross beta activity from each indicator station to the average gross beta activity from the control station. The results from this test show average activity detected at all indicator stations are statistically the same as the average activity detected at the control station. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2001.

Groundwater Groundwater samples were collected from one indicator location and analyzed for gamma radionuclides and tritium. W3 did not detect any gamma radionuclides in groundwater samples during the reporting period.

Tritium concentrations detected in 2001 are higher than those from the preoperational program as seen below. Results are reported as annual average pCi/I.

Monitoring Period Result Preoperational 121 1983 -2000 909 2001 775 Tritium is expected due to liquid effluent releases from the Turbine Building Industrial Waste Sump (TBIWS) and Dry Cooling Tower Sumps (DCTSs) normally being directed to the 40 Arpent canal where samples are collected for groundwater monitoring. Water from these pathways is typically discharged at a rate of approximately 20,000 gallons per day total with tritium concentration ranging from 6.1E-6 uCi/ml to 1.7E-5 uCi/ml. The plant effluent is diluted by adjoining canals and rain, which can vary significantly depending on weather conditions, prior to reaching the sample location. As a result, samples collected after periods of heavy rain can indicate concentrations below detection levels, while those collected during dry periods have the potential to approach concentrations discharged directly from the plant via the TBIWS and DCTSs.

22

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station As of March 14, 2002, the groundwater sample location was reclassified as Surface Water which requires the use of a continuous composite sampler. This sampling methodology should provide a better representation of the actual concentration of tritium at this location with less variability in sample results due to short-term changes in weather conditions.

2.4 Sediment Sample Results Sediment samples were collected from two indicator locations and analyzed for gamma radionuclides. Cesium-137, a man-made nuclide, was detected in one sample (SHWE-3) with a concentration of 53 pCi/kg. No other man-made radionuclides were detected in any of the samples.

The Cesium-137 results obtained during 2001 are consistent with those from the preoperational program and previous years of operation. In particular, the preoperational survey indicates that Cesium-137 was detected in 9 of 14 soil samples at concentrations ranging between 30 and 890 pCi/kg with an average concentration of 164 pCi/kg. Similarly, the range indicated during the previous years of operation was 18 to 142 pCi/kg with an average activity of 56 pCi/kg.

W3 has detected Cs-137 in wastewater tanks discharged to the Mississippi River at concentrations typically below 1E-6 uCi/mI in the past few years. After dilution by Circulating Water, this concentration is reduced to well below 1E-10 uCi/mI prior to mixing with the Mississippi River where it is diluted even further. At the minimal concentrations being discharged from W3 as compared to the typical Cs-137 concentrations commonly found in soils and sediments in Louisiana as a result of atmospheric fallout from nuclear weapons testing as noted in the preoperational study, plant operations is not expected to result in any appreciable quantities of radioactivity in sediment collected from the bank of the Mississippi River where SHWE-3 is located. In addition, the radioactivity detected in sediment this year is consistent with preoperatioal data even after applying a correction for natural decay of Cs-137.

Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2001.

2.5 Milk Sample Results Milk samples were collected from one indicator and one control location and analyzed for Iodine-131 and gamma radionuclides. Results indicate that all measurements were below the calculated LLDs. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2001.

2.6 Fish Sample Results Fish samples were collected from one indicator and one control location and analyzed for gamma radionuclides. Results indicate that all measurements were below the calculated LLDs. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2001.

23

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station 2.7 Broadleaf Vegetation Sample Results Broadleaf vegetation samples were collected from two indicator and two control locations and analyzed for Iodine-131 and gamma radionuclides. Results indicate that all measurements were below the calculated LLDs. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2001.

2.8 Land Use Census Results In compliance with the Waterford 3 ODCM and TRM, the land use census was conducted September 26 through September 28, 2000. The nearest residence, garden, beef cow, food product and milk animal in each sector within a five mile radius of the plant was located by visual inspection and verbal inquiry.

While milk cow and food product locations remained unchanged for 2000, three locations of goats (sectors N, P and Q) and one location of beef cow (sector F) were removed. Two new resident locations (sector B and G), four new garden locations (sectors C, N, P and Q), one new goat location (sector E) and one new beef cow location (sector G) was identified in 2000.

Based upon the locations identified in this survey, the locations identified in previous surveys and the locations currently being used to calculate dose commitments from liquid and gaseous effluents released from W3, no REMP sampling location changes are necessary.

Results of the 2000 biannual census are shown in Table 2.1.

2.9 Interlaboratory Comparison Results The River Bend Station Environmental Laboratory analyzed interlaboratory comparison samples for W3 to fulfill the requirements of Section 5.7.2 of the ODCM. Attachment 1 contains these results. For the sample result outside the acceptable control limit, W3 and RBS's review indicated no impact on previously reported data. Attachment 1 also provides additional discussion regarding the sample result outside the acceptable control limit.

a. The "known" values are listed with a range reflecting control (3 sigma) limits.

b. The normalized deviation from the "known" value is computed from the deviation and the standard error of the mean; +/-2.000 is the warning limit and +/-3.000 is the control limit. This is a measure of accuracy of the analytical methods.

c. The normalized range is computed from the mean range, the control limit, and the standard error of the range; +2.000 is the warning limit and +3.000 is the control limit. This is a measure of precision of the analytical methods.

d. The results reported were outside the control limits.

49

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station Interlaboratory Comparison Program Exceptions There was one result outside the control limit for accuracy in the 2001 cross check program participation study. This result was in a gamma isotopic analysis of a duplicate water sample.

The study result outside the control limit for accuracy was the Fe-59 analysis of a duplicate water sample E2817-125 (09/20/01). The Fe-59 result for the other water sample taken during this quarter was within the control limit. RBS normalized-deviation for the analysis was +3.24 with control limits of +/-3.00. This high bias result is considered conservative and has no impact on past results of the program. The bias high result for Fe-59 is contributed to coincidence summing effects. A coincidence summing correction was employed in the past, but was discontinued due to the production of non-conservative low-bias results. Fe-59 results were within control limits in other cross check samples for 2001. The normalized-deviations for Fe-59 in other samples during 2001 were 1.91, 2.63, 2.84, and 2.10.

• Calculation of the Mean and Standard Deviation The mean and standard deviation for different groups of analyses are calculated using the following equations:

i n and

0.5 where

X = mean of sample population, S = standard deviation of sample population, n = number of samples in sample population, and Xi = value of the i'th sample.

53

Annual Radiological 2001 Environmental Operating Report Waterford 3 Steam Electric Station

+ Comparing Two Sample Population Means The means of two sample populations are compared for statistical difference using the standard 't" test. The use of the test requires the assumption that the data within the populations are normally distributed and that the true standard deviations of the mean are equal for both populations. The standard 't' test tests the hypothesis that the true means of both populations are equal. The "t' value can be calculated from the equation below (obtained from the CRC Standard Mathematical Tables, 26th Edition (1981)):

X-Y t

where:

t = calculated "t" value, X = mean of first data set, Y = mean of second data set, 77x = number of variables in first data set, S x = standard deviation of first data set, 77 = number of variables in second data set, and S y = standard deviation of second data set.

The calculated 't" value is used to test the hypothesis that the true mean of the first population (m x) is equal to the true mean of the second population (m y) assuming that the true standard deviation of both populations are equal (m , = m y). The calculated "t" value is compared to a tabular 't' value such that:

a if t > t p,, then reject the hypothesis when m , > m y,

b. if t < -t P,n then reject the hypothesis when m x < m y,

c. if t > t p/2,, then reject the hypothesis when m x = m y, where t J/2,n and t J,n are the tabular "t" values, with a preselected error (5%), confidence level (1 - p) or (1 p/2), and degrees of freedom n = nx, + ny - 2. Tabular values of the "t" were obtained from the CRC Standard Mathematical Tables, 26th Edition (1981).
