Annual Radiological 2005 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, 2005. This report fulfills the requirements of W3 Technical Specification 6.9.1.7.

During 2005, gross beta radioactivity was detected in air and drinking/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 during 2005 at indicator sediment location SHWK-

1. 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 2005 is more than likely attributable to weapons testing fallout.

Cesium-137 was detected during 2005 at control milk location MKR-38. This is consistent with results obtained from the preoperational program and previous years of operation. The level of Cesium-137 in the sample was below both the reporting level and the LLD level required by the Waterford 3 TRM.

Tritium was detected in two samples during 2005 at indicator surface water location SWK-1. Tritiim is discharged to this location during maintenance periods only. The primary pathway is through circulating water discharge. The levels of tritium in these samples are below both the reporting level and the LLD level required by the Waterford 3 TRM.

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 broad leaf vegetation, as well as measuring radiation directly.

The REMP includes sampling indicator and control locations within a 38-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 2005, 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. The review of 2005 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 2)05.

Therefore, no analysis or planned course of action to alleviate problems was necessary.

I

Anrual Radiological 2C105 Environmental Operating Report Waterford 3 Steam Electric Station ReSporting Levels W2'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, 2005 results did not trigger any Radiological Monitoring Program Special Reports.

Radioactivity 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 Milk samples for the 3rd and 4 th quarter of 2005 were unavailable from indicator location MKE-3 due to cows not producing enough milk. One sample from control location MKR-40 was unavailable during the 1 st quarter due to owner selling the cows. With the absence of milk samples at these locations, broad leaf 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. 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.

  • TLDs During the third quarter, TLDs from station R-1 were removed from their location and returned to Waterford 3. Another set of TLDs were placed at this location and read at the end of the quarter.

+ Missed Samples TLDs located at stations G-2 and GA were missing at the time of the first quarter exchange.

TLDs located at station J-15 were missing at the time of the second quarter exchange. TLIDs located at stations F-2 and GA were missing at the time of the third quarter exchange.

  • Required Lower Limit of Detection (LLD) Values All LLDs during this reporting period were within the acceptable limits required by the W3 TRA.
  • 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 The following changes were made to the ODCM during 2005:
  • The description for TLD location GA and J-1 5 was revised.
  • Milk location MKR-40 was deleted from the program.
  • Milk location MKR-38 was added to the program.

Anrual Radiological 2(105 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 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 2005 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 biennially, 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 are to determine the location in each sector of the nearest:

1) Residence
2) Animal milked for human consumption
3) Garden of greater than 50 m (500 ft ) producing broad leaf 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 :2005 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, lodine-131 and gamma radionuclides (quarterly air particulate filter composites only). W3 did not detect any gamma radionuclides in the quarterly air particulate composites or lodine-131 in the radioiodine cartridges during the reporting period, as has been the case in previous years. Indicator gross beta air particulate results for 2005 were similar to those background levels obtained in previous years of the operational REMP and well below preoperational levels as seen below.

3 Results are reported as annual average pCi/Mi Monitoring Period Result Preoperational 0.080 1983- 2004 0.019 2005 0.019 Table 3.1, which includes gross beta concentrations for 2005, provides a comparison cf 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 2005.

2.2 Thermoluminescent Dosimetry Sample Results The average exposure rates during 2005 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 15 mrem/standard quarter with an average exposure rate of 12 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 five mrem at one location (D-2).

As shown in Attachment 2, Table 2.1, the standard Yt" 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 and 2-5 miles from the plant are statistically the same as those > 5 miles.

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 2005 as previous years of operation as evidenced on Attachment 2, Table 2.2. In addition, Radiological Gaseous Effluents for 2005 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.

Annual Radiological 2005 Environmental Operating Report Waterford 3 Steam Electric Station 2.3 Water Sample Results Analytical results for 2005 drinking/surface water 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 lodine-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 were below previous operational and preoperational years as seen below.

Results are reported as annual average pCi/l.

Monitoring Period Result Preoperational 7.0 1983-2004 5.0 2005 3.5 Table 3.1, which includes gross beta concentrations for 2005, 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 indicator stations to the average gross beta activity from the control station. Since there was only one result out of four of gross beta activity for indicator station DWE-5 (three results were less than), a statistical comparison to control station DWP-7 could not be performed. The statistical comparison for indicator station DWF-2 to control station DWP-7 shows that average activity detected at this station is statistically the same as average activity detected at the control station. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2005.

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

Tritium concentrations detected in 2005 are slightly higher than those from the preoperat onal program and well below previous operational years. Results are reported as annual average pCi/l.

Monitoring Period Result Preoperational 121 1983 -2004 2620 2005 622 Tritium was detected in two out of four samples with a concentration of 291 and 953 pCi,'liter.

The levels of tritium in these samples are below both the reporting level and the LLD level required by Waterford 3 TRM. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2005.

Annual Radiological 20C5 Environmental Operating Report Waterford 3 Steam Electric Staticn 2.4 Sediment Sample Results Sediment samples were collected from two indicator locations and one control location and analyzed for gamma radionuclides. Cesium-137, a man-made nuclide, was detected in sample SHWK-1 with a concentration of 38 pCi/kg. No other man-made radionuclides were detected in any of the samples.

The Cesium-137 results obtained during 2005 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 57 pCi/kg.

W3 has detected Cesium-137 in wastewater tanks discharged to the Mississippi River at concentrations typically below 1E-6 uCi/ml in the past few years. After dilution by Circulating Water, this concentration is reduced to well below 1E-10 uCi/ml 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 Cesium-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. In addition, the radioactivity detected in sediment this year is consistent with preoperational data even after applying a correction for natural decay of Cesium-137.

Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2005.

2.5 Milk Sample Results Milk samples were collected from one indicator and one control location and analyzed for lodine-131 and gamma radionuclides. Results from lodine-131 analyses indicate that all measurements were below the calculated LLDs. Further, Cesium-137 was detected in one control sample MKR-38 on 03-15-05 at a concentration of 5.23 pCiII. The sample was recounted twice on 03-15-05 with results of 3.65 and 5.25 pCi/I respectively. Another sample was collected and analyzed on 03-22-05. Cesium-137 was detected at a concentration of 6.03 pCi/l. The levels of Cesium-137 in these samples are below both the reporting level and the LLD level required by Waterford 3 TRM. Therefore, W3 concluded that plant operations had no significant impact on this pathway during 2005.

2.6 Fish Sample Results Fish samples were collected from two indicators 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 2005.

Results indicate that all measurements were below the calculated LLDs. Therefore, W3 concluded that plant operations hai no significant impact on this pathway during 2005.

2.8 Land Use Census Results In compliance with the Waterford 3 ODCM and TRM, the land use census was conducted on September 27, 28 and 29, 2004. 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 residence, milk cow and food product locations remained unchanged for 2004, one location of goats (sector E) and two locations of beef cows (sector G) were removed. Two new garden locations (sector C and D), and three new goat locations (sector E, F and Q) were identified in 2004. 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 2004 biennial 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 I contains these results.

(a) The known value as determined by Analytics.

(b) The normalized deviation from the "known" value is computed from the deviation and the standard error of the mean; +/-2.00 is warning limit and +/-3.00 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 out of the control limits.

Exceptions:

There was one result outside the control limits for accuracy in the 2005 Interlaboratory Comparison program participation studies. This result was in a gamma isotopic analysis of al sed ment/soil sample.

The result outside'the control limits for accuracy was in the analysis of the nuclide Mn-54 ir, Analytics sample number E4718-125 of 9/15/2005. RBS normalized-deviation for the analysis was +4.28 with control limits of +/-3.00. This high bias result is considered conservative and is considered as having no impact on past results of the program. Mn-54 results were all within con:rol limits in other program samples for the year 2005; with normalized-deviation of 0.55 in a water sample analysis; 0.21 in an air filter sample analysis; and 0.18 in a milk sample analysis.

Review of trending information of Mn-54 results in sediment/soil samples indicates a steady high bias, with only one result for Mn-54 out of the control limits in 1998. Reanalysis of the 2005 soi sample produced results very similar to the original averaged result.

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

,=1, and 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.

  • Comrparing 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 aid that the t-ue standard deviations of the mean are equal for both populations. The standard "t" test tests the hypo:hesis 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 GI"2 _ )S2 +( I)S,2 .50 1 0'5 nx+ ny-2 n.,

where:

t = calculated "'Tvalue, X = mean of first data set, Y = mean of second data set, t = number of variables in first data set, S , = standard deviation of first data set, q = 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 ,) is equal to the true mean of the second population (m y)assuming that the true standard deviation of both populations are equal (m x= 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 pAn then reject the hypothesis when mx m y,
c. if t > t p/2, then reject the hypothesis when m x = m y, where t p/2,n and t p,, are the tabular "t" values, with a preselected error (5%), confidence level (1- pu)or (1- p/2), and degrees of freedom n = n, + ny - 2. Tabular values of the 't" were obtained from the CRC Standard Mathematical Tables, 26th Edition (1981).
