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, 2011 through December 31, 2011. 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 2011, 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 2011. No measurable levels of radiation above baseline levels attributable to River Bend Station operation were detected in the vicinity of RBS. The 2011 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 Pro2ram 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 approximate 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 2011, 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 2011 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 2011. Therefore, no analysis or planned course of action to alleviate problems was necessary.
1
Reportinu Levels River Bend Station reviews indicate that no REMP sample 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, 2011 results did not require any Radiological Monitoring Program Special Reports.
Radioactivity Not Attributable to RBS The RBS REMP has detected radioactivity attributable to other sources not associated with the operation of RBS. These instances are summarized as follows:
- In 2011, 1-131 was detected in a control vegetation sample, and indicator and control air sample media, which was credibly attributed to the trans-Pacific transport of airborne releases from Dai-Ichi, Fukushima following the March 11, 2011 Tohoku earthquake.
- In 1986, following the radioactive plume release due to reactor core degradation at the Chernobyl Nuclear Power Plant, RBS REMP detected 1-131 in water, vegetation, and air samples.
- 1-131 was also detected during 1998 in the wastewater treatment plant effluent, which was attributed to the medical treatment of a RBS employee.
- In 2006, Cs-137 was detected in upstream and downstream Mississippi River sediment samples. This activity was not present in the 2011 samples.
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 (Thermoluminescent Dosimeter)
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 co-located air sample locations, 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 kin) of RBS in 2011 due to unavailability of milk-producing animals used for human consumption. The RBS Technical Requirements Manual requires collection of milk samples if available commercially 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 LLD values during this reporting period were within the acceptable limits required by the RBS Technical Requirement Manual (TRM).
- Sampling Deviations Listed below are sampling deviations that occurred during 2011.
No LLD values were exceeded in the air sampling 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.

- 1. Introduction 1.1. Radiological Environmental Monitoring Program River Bend Station 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 the following:
" 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 2011 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 last land use census was performed in 2010. The next scheduled Land Use Census will be performed in 2012.
Section 2.8 of this report contains a narrative on the results of the 2010 land use census.

- 2. Interpretation and Trends of Results 2.1. Air Particulate and Radioiodine Sample Results Iodine-131 attributable to RBS was not detected in the radioiodine cartridges during 2011 as has been the case in previous years. Indicator gross beta air particulate results for 2011 were similar to preoperational and operational levels as seen below. Results are reported as annual average pCi/m 3 (picocuries per cubic meter).
Monitoring Period Result Preoperational 0.030 2011 0.026 2010 0.024 2009 0.023 2008 0.023 2007 0.024 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 shows a comparison of indicator results from 2011.
2.2. Thermoluminescent Dosimetry Sample Results Gamma radiation exposure in the reporting period compares to previous years.
Figure 2-1 compares quarterly indicator results for 2011 with control location data from 1986 to 2010. All indicator results were within three-sigma of 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 indicator 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.
The result of one 2nd quarter 2011 indicator TLD (TN1) was unavailable due to that TLD being missing at change out.
15
2.3. Water Sample Results Analytical results for 2011 surface water and groundwater samples were similar to those reported in previous years.
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 2011 results from the indicator location as compared to the preoperational and previous operational years.
Results are reported as annual average pCi/1 (picocuries per liter).

2.4. Shoreline Sediment Sample Results A shoreline sediment sample was collected from the indicator location in 2011 and analyzed for gamma radionuclides. RBS also samples a non-REMP upstream control sediment sample. A review of historical indicator and upstream sediment samples periodically shows Cs-137. No Cs-137 was indicated on the samples in, 2011.
Therefore, based on these measurements, RBS operations had no significant radiological impact upon the environment or public via this pathway.
2.5. Milk Sample Results Milk samples were not collected during 2011 due to the unavailability of indicator locations within 5 miles (8 kin) 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 2011.
16
2.6. Fish and Invertebrate Sample Results Fish samples were collected from two locations (indicator and control) and analyzed for gamma radionuclides. In 2011, gamma radionuclides were below detectable limits that were 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 2011 and analyzed for gamma radionuclides in accordance with Table TRM 3.12.1-1. The 2011 levels attributable to RBS" 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 Land Use Census was conducted in accordance with procedure ESP-8-051, as required by Technical Requirements Manual (TRM) (TR 3.12.2).
A garden census is not conducted pursuant to the note in the TRM (TLCO 3.12.2) that allows the sampling of broadleaf vegetation in the highest calculated average ground-level D/Q sector near site boundary in lieu of the garden census.
The milk animal census identified no milk animals within 8 km (5 miles) of River Bend site. This information was verified by the County Agents from West Feliciana, East Feliciana, and Pointe Coupee parishes.
The resident census changes are noted in Table 2.1. One resident was added to account of the Point Coupee Parish Detention Center. See the comments in Table 2.1 for specific information regarding changes.
No locations were identified in 2011 that would yield a calculated dose or dose commitment greater than those contained in the TRM (TR 3.11).
Table 2.1 contains data from the most recently completed Land Use Census.

2.9. Interlaboratory Comparison Results The River Bend Station Environmental Laboratory analyzed interlaboratory comparison samples to fulfill the requirements of Technical Requirements Manual 3.12.3. Attachment 8.1 contains these results. The interlaboratory comparison results indicated that 100% of the sample results for accuracy and precision were within the acceptable control limits.

g LLD = Required lower limit of detection based on RBS Technical Requirements Manual Table 3.12.1-3.
Mean and range based upon detectable measurements only. Fraction of detectable measurements at specified locations is indicated in parenthesis (F).
Locations are specified (1) by name and (2) direction and distance relative to reactor site.
Non-routine results are those which exceed ten times the control station value. If no control station value is available, the result is considered non-routine if it exceeds ten times the preoperational value for the location.
LLD is not defined in RBS Technical Requirements Manual Table 3.12.1-3.
Control location for sediment is upstream surface water sample.
REMP samples obtained from this location during 2011 identified detectable concentrations of isotopes that could be related to operation of River Bend Station (RBS) Given the following facts, the detectable concentrations are not a result of RBS operation:
o The quantities of radioactive airborne effluents from RBS during 2011 did not increase significantly compared to year 2010.
o Prior REMP sample results have not detected the presence of these isotopes in samples which could be attributed to RBS.
o The concentrations detected in indicator samples were also identified in the associated control samples.
As such, the atypical detection of these radionuclides in both indicator and control samples is credibly attributed to the trans-Pacific transport of airborne releases from Dai-lchi, Fukushima following the March 11, 2011 Tohoku earthquake and is not related to the operations of RBS.
