SUMMARY
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, 2004 through December 31, 2004.
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 NPF47. During 2004, 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 2004. No measurable levels of radiation above baseline levels were detected in the vicinity of River Bend Station. The 2004 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 Monitoring 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 kIn) 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 2004, 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 2004 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 Damage The REMP monitoring did not detect any harmful effects or evidence of irreversible damage in 2004.
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, 2004 results did not trigger any Radiological Monitoring Program Special Reports.
Radioactivity Not Attributable to RBS The RBS REMP detected no radioactivity attributable to other sources during year 2004.
Following the radioactive plume release due to reactor core degradation at the Chernobyl Nuclear Power Plant in 1986, RBS REMP detected I-131 in water, vegetation, and air samples. I-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 2004 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).
- Sampling Deviations Listed below are sampling deviations that occurred during 2004. Two deviations resulted in missed TLD samples. No LLD values were exceeded in the air sample deviations. 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.

- Missed Samples A Mississippi River shoreline sediment sample was not collected per plant schedule on 12/8/04, due to unusual high river stage during December. The sample was finally collected on 2/21/05 after the river stage had receded to allow sampling at the shoreline.
The actual collection date was within the surveillance late date. The sediment sampling surveillance will be performed during the low flow conditions for 2005.

- Unavailable Results The results from two TLD locations were unavailable during year 2004 due to missing badges at collection.
Two fourth quarter 2004 TLD badges were found missing at locations TJ1 and TNS.
Location TJ1 (Sector J, South) was destroyed by power line right-of-way clearing activities. Part of the TLD holder cage was found in the immediate area. Location TNS (Sector N, West, Special) was missing due to mischievous activity. Its location is in a heavy traffic area at the Mississippi River west bank ferry landing. This was the first time a badge has been missing from this location. Additional incidents may necessitate the relocation of this TLD station.
Program Modifications RBS made no modifications to the REMP during the year 2004.
Attachments contains results of air, TLD, water, sediment, fish, food products and special samples collected in 2004. TLDs were analyzed by Waterford-3 Dosimetry. All remaining samples were analyzed by RBS Environmental Laboratory. Attachment 1 also contains RBS' participation in the interlaboratory comparison program during the year 2004.

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 2004 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.
A land use census was performed in 2004. 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 the location in each sector of the nearest:
- 1) Residence
- 2) Animal milked for human consumption
- 3) Garden of greater than 50 m2 (500 fR2) 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 County Agents from each parish area is used especially in verifying the presence of milk animals in the five mile radius of River Bend.
- As a result of these surveys, the following information is obtained in each meteorological sector:
- 1) Nearest permanent residence
- 2) Nearest milking animal
Distance and direction from RBS reactor building is also determined by use of a GPS instrument.
- 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 2004, as has been the case in previous years.
Indicator gross beta air particulate results for 2004 were similar to preoperational and operational levels as seen below. Results are reported as annual average pCi/m3.
Monitoring Period Result Preoperational 0.030 2004 0.018 2003 0.021 2002 0.020 2001 0.021 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 from 2004 versus control location data from 1986 to 2003. Two indicator results for 2004 were out of the upper three-sigma limit for the control data. These results, from two indicator locations, ranging from 0.035 to 0.037, with the upper 3-sigma control limit 3
of 0.032 pCi/m 2.2 Thermoluminescent Dosimetry Sample Results Gamma radiation exposure in the reporting period compares to previous years and remains below preoperational levels. Figure 2-1 compares quarterly indicator results for 2004 with control location data from 1986 to 2003. All indicator results are within the upper control three-sigma limit for the control data.
RBS normalizes measured exposure 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 2004 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 2004 results from the indicator location as compared to the preoperational and previous operational years. Results are reported as annual average pCi/l.

<LLD Based on these comparisons, the operation of RBS had no impact on this pathway during 2004, 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 2004 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 2004 and analyzed for gamma radionuclides.
Gamma radionuclides Cs-134 and Cs-137 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.
RBS personnel also collected special sediment samples from East Creek and West Creek during 2004 to supplement the REMP.
RBS did not detect any gamma 17
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 2004 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 2004.
2.6 Fish and Invertebrate Sample Results Fish samples were collected from two locations (indicator and control) and analyzed for gamma radionuclides. In 2004, 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 2004 and analyzed for Iodine-131 and gamma radionuclides. The 2004 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 A land use census was conducted during the 2004 in accordance with RBS Technical Requirements Manual 3.12.2. Although there were some minor changes between the 2002 and 2004 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. Most of these changes were due to the use of a GPS instrument in locating the resident's bearing and range from the reactor building, as compared to previous methods used in this process.
In addition, no dairy animals were found within 8 km of RBS during the 2004 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.,
2004 Radiological Environmental Monitoring Report, contains these results. RBS's review of interlaboratory comparison results indicated that 100% of the sample results for accuracy and precision were within the acceptable control limits.
