OF MONITORING RESULTS 28 iv

Summary The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for the River Bend Station (RBS) Radiological Environmental Monitoring Program (REMP) for the period January 1, 2003 through December 31, 2003. This report fulfills a requirement specified in RBS Technical Requirements Manual (TRM) 5.6.2 as required by Technical Specification 5.6.2 of Appendix A to RBS License Number NPF-47. During 2003, REMP results remained at background levels, as has been the case in previous years.

All required lower limit of detection (LLD) capabilities were achieved in all sample analyses during 2003. No measurable levels of radiation above baseline levels were detected in the vicinity of River Bend Station. The 2003 Radiological Environmental Monitoring Program thus substantiated the adequacy of source control and effluent monitoring at River Bend Station with no observed impact of plant operations on the environment.

Radiological Environmental Monitorin2 Program RBS established the REMP prior to the station's becoming operational (1985) to provide data on background radiation and radioactivity normally present in the area. RBS has continued to monitor the environment by sampling air, water, sediment, fish and food products, as well as measuring direct radiation. RBS also samples milk if milk-producing animals used for human consumption are present within five miles (8 km) of the plant.

The REMP includes sampling indicator and control locations within an approximately 20-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. RBS personnel compare indicator results with control and preoperational results to assess any impact RBS operation might have had on the surrounding environment.

In 2003, environmental samples were collected for radiological analysis. The results of indicator locations were compared with control locations and previous studies. It was concluded that overall, no significant relationship exists between RBS operation and effect on the area around the plant. The review of 2003 data, in many cases, showed radioactivity levels in the environment were undetectable in many locations and near background levels in significant pathways.

Harmful Effects or Irreversible Dama2e The REMP monitoring did not detect any harmful effects or evidence of irreversible damage in 2003. Therefore, no analysis or planned course of action to alleviate problems was necessary.

1

Reporting Levels RBS's review indicates that no samples equaled or exceeded reporting levels for radioactivity concentration in environmental samples, as outlined in RBS Technical Requirements Manual Table 3.12.1-2, when averaged over any calendar quarter. Therefore, 2003 results did not trigger any Radiological Monitoring Program Special Reports.

Radioactivity Not Attributable to RBS The RBS REMP detected gamma nuclide Cs-137 in a down stream river sediment sample during 2003. This nuclide was quantified at a level below the LLD requirement. Since the detection of Cs-137 is not uncommon in soils and sediments, attributing this radioactivity to RBS is very doubtful. Additional discussion is offered in Sediment Sample Results.

Following the radioactive plume release due to reactor core degradation at the Chernobyl Nuclear Power Plant in 1986, RBS REMP detected 1-131 in water, vegetation, and air samples. 1-131 was also detected during 1998 in the wastewater treatment plant effluent.

This was attributed to the medical treatment of a RBS employee.

Comparison to Federal and State Programs RBS personnel compared REMP data to federal and state monitoring programs as results became available. Historically, the programs used for comparison have included the U.S.

Nuclear Regulatory Commission (NRC) TLD Direct Radiation Monitoring Network and the Environmental Radiological Laboratory - Department of Environmental Quality Laboratory Services Division (ERL-DEQLSD).

The NRC TLD Network Program was discontinued in 1998. Historically these results have compared to those from the RBS REMP. RBS TLD results continue to remain similar to the historical average and continue to verify that plant operation is not affecting the ambient radiation levels in the environment.

The (ERL-DEQLSD) and the RBS REMP entail similar radiological environmental monitoring program requirements. These programs include collocated air samples and splitting or sharing sample media such as water, fish and food products. Both programs have obtained similar results over previous years.

Sample Deviations

  • Milk The REMP did not include milk sampling within five miles (8 km) of RBS in 2003 due to unavailability of milk-producing animals used for human consumption. RBS's Technical Requirements Manual requires collection of milk samples if available commercially 2

within 8 km (5 miles) of the plant. RBS personnel collected vegetation samples to monitor the ingestion pathway, as specified in RBS Technical Requirements Manual Table 3.12.1-1, because of milk unavailability.

Required Lower Limit of Detection (LLD) Values All LLDs during this reporting period were more conservative than the acceptable limits required by the RBS Technical Requirement Manual (TRM).

Air Samples Listed below are sample/sampling deviations that occurred during 2003. These deviations did not result in a missed sample and no LLD values were exceeded. As described in footnote (a) to RBS Technical Requirements Manual Table 3.12.1-1, deviations are permitted from the required sampling schedule due to malfunction of equipment or other legitimate reasons.

1.0 Introduction 1.1 Radiological Environmental Monitoring Program RBS 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 RBS.
  • 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 the RBS Technical Requirements Manual 3.12.1. A description of the RBS REMP sample locations utilized to monitor exposure pathways are described in Table 1.1 and shown in Figures 1-2 and 1-3. RBS may occasionally supplement this program with additional sampling in order to provide a comprehensive and well-balanced program.

Section 2.0 of this report provides a discussion of 2003 sampling results with Section 3.0 providing a summary of results for the monitored exposure pathways.

1.3 Land Use Census RBS personnel conduct a land use census biannually, as required by RBS Technical Requirements Manual 3.12.2. The land use census was performed in 2002. The purpose of this census is to identify changes in uses of land within five miles of RBS that would require modifications to the REMP or the Technical Requirements Manual. The most important criteria during this census is to determine 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
  • 5

The method used by RBS personnel for conducting this land use census is as follows:

  • RBS personnel conduct door-to-door field surveys and/or aerial surveys in each meteorological sector out to five miles in order to locate the nearest resident and milk animal.
  • Consultation with local agricultural authorities is used in instances when personal contact cannot be made.
  • As a result of these surveys, the following information is obtained in each meteorological sector:
1) Nearest permanent residence
2) Nearest milking animal
  • RBS personnel identify locations on the map, measure distances to RBS and record results.
  • Locations, if any, are identified which yield a calculated dose or dose commitments greater than those currently calculated in the Technical Requirements Manual.
  • RBS personnel compare results to previous census.
  • RBS personnel do not perform a garden census since Technical Requirements Manual 3.12.2 allows the routine sampling of broadleaf vegetation in the highest D/Q sector near the site boundary in lieu of the garden census.

2.0 Interpretation and Trends of Results 2.1 Air Particulate and Radioiodine Sample Results Iodine-131 was not detected in the radioiodine cartridges during 2003, as has been the case in previous years. Indicator gross beta air particulate results for 2003 were similar to preoperational and operational levels as seen below. Results are reported as annual average pCi/m3 .

Monitoring Period Result Preoperational 0.030 2003 0.021 2002 0.020 2001 0.021 2000 0.020 Table 3.1 provides a comparison of the indicator and control location mean values, which further emphasizes that the airborne pathway continues to remain at background levels. Figure 2-2 also shows a comparison of indicator results versus control location data from 1986 to 2002. Six indicator results for 2003 were above the upper three sigma limit for control data. These results, from all indicator locations, range from 0.033 to 0.037 pCi/m, with the upper 3-sigma control limit of 0.032. All six results were from the time period 9/2/03 to 10/13/03, typically the driest period of the year. Increased gross beta results are often experienced due to increased dust particulates in the air.

2.2 Thermoluminescent Dosimetry Sample Results Gamma radiation dose in the reporting period compares to previous years and remains below preoperational levels. Figure 2-1 compares quarterly indicator results for 2003 with control location data from 1986 to 2002. All indicator results are below the upper control three-sigma limit.

RBS normalizes measured doses to 90 days and relies on comparison of the indicator locations to the control as a measure of plant impact. RBS's comparison of the inner ring and special interest area TLD results to the controls, as seen in Table 3.1, indicates that the ambient radiation levels are unaffected by plant operations.

Therefore, levels continue to remain at or near background.

2.3 Water Sample Results Analytical results for 2003 surface water and groundwater samples were similar to those reported in previous years.

16

Surface water samples were collected from two locations (indicator and control) and analyzed for gamma radionuclides and tritium. Gamma radionuclides were below detectable limits at the indicator and control locations. Tritium was also below detectable limits at all locations. Listed below is a comparison of 2003 results from the indicator location as compared to the preoperational and operational years.

Results are reported as annual average pCi/l.

Radionuclide 2003 1996 - 2002 Preoperational Gammas <LLD <LLD <LLD Tritium <LLD 258* <LLD

  • Average tritium value quantified less than LLD of 3000.

Groundwater samples were collected from two locations (indicator and control) and analyzed for gamma radionuclides and tritium. Gamma radionuclides and Tritium were below detectable limits at the indicator and control locations. Listed below is a comparison of 2003 results from the indicator location as compared to the preoperational and operational years. Results are reported as annual average pCi/l.

Radionuclide 2003 1996 - 2002 Preoperational Gammas <LLD <LLD <LLD Tritium <LLD 290* <LLD

  • Tritium value quantified less than the LLD of 3000.

Based on these comparisons, the operation of RBS had no impact on this pathway during 2003, and levels of radionuclides monitored for this pathway continue to remain similar to those obtained in operational and preoperational years.

RBS personnel also collected special effluent wastewater samples from the wastewater treatment plant during 2003 to supplement the REMP. RBS did not detect any gamma radionuclides in these samples, which were analyzed to RBS TRM LLD requirements for water.

2.4 Sediment Sample Results Sediment sample was collected from the indicator location in 2003 and analyzed for gamma radionuclides. Gamma radionuclide Cs-134 was below detectable limits, which is consistent with the preoperational and operational monitoring periods.

Gamma nuclide Cs-137 was quantified in the down stream river shoreline sediment at 60.8 pCi/kg. This quantified result is less than the Cs-137 LLD of 180 pCi/kg. No reportable level of radioactivity concentrations is defined for environmental sediment samples in the RBS TRM. Additional sampling of river shoreline sediment was 17

performed with no Cs-137 activity detected. Therefore, based on these measurements, RBS operations had no significant radiological impact upon the environment or public by this pathway.

RBS personnel also collected special sediment samples from East Creek and West Creek during 2003 to supplement the REMP. RBS did not detect any gamma radionuclides in these samples, which were analyzed to RBS TRM LLD requirements for sediment.

2.5 Milk Sample Results Milk samples were not collected during 2003 due to the unavailability of indicator locations within 5 miles (8 km) of RBS. Since there are no dairies within five miles of the RBS site, it is concluded RBS's operation had no impact on this pathway in 2003.

2.6 Fish and Invertebrate Sample Results Fish samples were collected from two locations (indicator and control) and analyzed for gamma radionuclides. In 2003, gamma radionuclides were below detectable limits, which is consistent with the preoperational and operational monitoring periods.

Therefore, based on these measurements, RBS operations had no significant radiological impact upon the environment or public by this pathway.

2.7 Food Product Sample Results Food product samples were collected when available from two locations (indicator and control) in 2003 and analyzed for Iodine-131 and gamma radionuclides. The 2003 levels remained undetectable, which is consistent with previous operational years. Therefore, since levels continue to remain at background, it can be concluded that plant operations is not impacting this pathway.

2.8 Land Use Census Results The last land use census was conducted during the 2002 growing season in accordance with RBS Technical Requirements Manual 3.12.2. Although there were some minor changes between the 2000 and 2002 census as seen in Table 2-1, the land use census did not identify any location(s) that yields a calculated dose or dose commitment greater than the values currently being calculated in requirement TSR 3.11.2.3.1. In addition, no dairy animals were found within 8 km of RBS during the 2002 census.

RBS personnel did not perform a garden census since Technical Requirements Manual 3.12.2 allows the routine sampling of broadleaf vegetation in the highest D/Q sector near the site boundary in lieu of the garden census.

18

2.9 Interlaboratory Comparison Results RBS' Environmental Laboratory analyzed interlaboratory comparison samples to fulfill the requirements of Technical Requirements Manual 3.12.3. Attachment 1, 2003 Radiological Environmental Monitoring Report, contains these results. RBS's review of interlaboratory comparison results indicated that 98% of the sample results for accuracy were within the acceptable control limits of the three normalized deviations. For those sample results outside the acceptable control limits, RBS's review indicated no impact on previously reported data. Attachment 1 also provides additional discussion regarding sample results outside the acceptable control limits.

(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 out of the control limits.

Exceptions:

There was one result outside the control limits for accuracy in the 2003 cross check program participation studies. This result was in a gamma isotopic analysis of a water sample.

The result outside the control limits for accuracy was in the analysis of the nuclide 1-131 in sample study E3755-125 of 6/12/2003. RBS normalized-deviation for the analysis was +3.06 with control limits of +/-3.00. This slightly high bias result is considered conservative and is considered as having no impact on past results of the program. I-131 results were all within control limits in other cross check samples for the year; with normalized-deviation of 0.09 in charcoal cartridge analysis, and -0.90 in a milk sample analysis.
