SUMMARY
Radiological Environmental Monitoring Program I
Page 5 of 44 The Annual Radiological Environmental Operating Report presents data obtained through analyses of environmental samples collected for River Bend Station (RBS)
Radiological Environmental Monitoring Program (REMP) for the period January 1 through December 31, 2022. This report fulfills the requirements of RBS Technical Specification 5.6.2 of Appendix A to RBS License Number NPF-47.
All required lower limit of detection (LLD) capabilities were achieved in all sample analyses during 2022, as required by the RBS Technical Requirement Manual (TRM).
No measurable levels of radiation above baseline levels attributable to River Bend Station operation were detected in the vicinity of RBS. The 2022 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.
River Bend Station 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 2022, environmental samples were collected for radiological analysis. The results of indicator locations were compared with control locations and previous studies. It was concluded that no significant relationship exists between RBS operation and effect on the area around the plant. The review of 2022 data showed radioactivity levels in the environment were undetectable in many locations and near background levels in significant pathways.
Reporting Levels No samples equaled or exceeded reporting levels.

Page 6 of 44 Annual Radioloalcal Environmental Ooeratlna Report Comparison to State and Federal Program RBS personnel compared REMP data to state monitoring programs as results became available. Historically, the programs used for comparison have included the U.S. Nuclear Regulatory Commission (NRC) Thermoluminescent Dosimeter (TLD)
Direct Radiation Monitoring Network and the Louisiana Department of Environmental Quality - Office of Environmental Compliance (LDEQ-OEC).
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 LDEQ-OEC and the RBS REMP entail similar radiological environmental monitoring program requirements. These programs include co-located air samples and splitting or sharing sample media such as water, sediment and fish. Both programs have obtained similar results over previous years.
Sample Deviations During 2022, environmental sampling was performed for eight media types addressed in the ODCM and for direct radiation. A total of 328 samples of the 328 scheduled were obtained. Of the scheduled samples, 100 percent were collected and analyzed in accordance with the requirements specified in the ODCM. contains the listing of sample deviations and actions taken.
Program Modifications There were no program modifications during the reporting period.

River Bend Station I
Year:2022 Annual Radiological Environmental Operating Report INTRODUCTION Radiological Environmental Monitoring Program I
Page 7 of 44 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:
Analyzing applicable 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 River Bend Station.
Correlating levels of radiation and radioactivity in the environment with radioactive releases from station operation.
2.2 Pathways Monitored 2.3 The airborne, direct radiation, waterborne and ingestion pathways are monitored as required by RBS TRM 3.12.1. A description of the REMP utilized to monitor the exposure pathways is described in the attached Tables and Figures.
Section 4.0 of this report provides a discussion of 2022 sampling results with Section 5.0 providing a summary of results for the monitored exposure pathways.
Land Use Census RBS conducts a land use census biennially, as required by 3.12.2 of the TRM. 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 and the Offsite Dose Calculation Manual (ODCM/TRM). The next scheduled land use census will be performed in 2024. Section 4.5 on the report contains a narrative on the results of the 2022 land use census.

.I!
u In 2022 there were no samples above the LLD for 1-131. Indicator gross beta air particulate results for 2022 were comparable to results obtained from 2012-2021 of the operational REMP. Also, the 2022 gross beta annual average was less than the average for preoperational levels. Results are reported as annual average picocuries per cubic meter (pCi/m3).
Monitoring Period 2012 - 2021 (Minimum Value) 2022 Average Value 2012 - 2021 (Maximum Value)
Preoperational Result 0.016 0.020 0.024 0.030 Gross beta activity is attributed to naturally occurring radionuclides. Table 6, which include gross beta concentrations and provide a comparison of the indicator and control means and ranges emphasizes the consistent trends seen in this pathway to support the presence of naturally occurring activity. Therefore, it can be concluded that the airborne pathway continues to be unaffected by River Bend Station operations.

f 1 2.00 1 0.00 4.3 River Bend Station reports measured dose as net exposure (field reading less transit reading) normalized to 90 days and relies on comparison of the indicator locations to the control as a measure of plant impact. River Bend Station's comparison of the indicator and special interest area TLD results to the control, as seen in Table 6, identified no noticeable trend that would indicate that the ambient radiation levels are being affected by plant operations. In addition, the indicator value of 13.3 millirem (mrem) shown in the TLD radiation dose comparison graph below shows the 2022 concentration is comparable to historic results. Overall, River Bend Station concluded that the ambient radiation levels are not being affected by plant operations.

4th 0r Analytical results for 2022 surface water and groundwater water samples were similar to those reported in previous years. Gamma radionuclides and tritium analytical results for 2022 waterborne samples were below the ODCM-required LLD similar to those reported in previous years. These results are further explained below.
Plant: River Bend Station I
Year: 2022 Annual Radiological Environmental Operating Report I Page 19 of 44 4.3.1 Surface Water Results Samples were collected from one indicator and one control location and analyzed for gamma radionuclides and tritium. Tritium and gamma radionuclides were below detectable limits which is consistent with results seen in previous operational years.
Therefore, the operation of River Bend Station had no definable impact on this waterborne pathway during 2022.
4.3.2 Groundwater Results Samples were collected from one indicator and one control location. Groundwater samples were analyzed for gamma radionuclides and tritium. Gamma radionuclides and tritium concentrations were below the LLD limits at the indicator and control locations. The operation of River Bend Station had no definable impact on this waterborne pathway during 2022.
4.3.3 Sediment Sample Results 4.4 4.4.1 Sediment samples were collected from one indicator and one control location in 2022 and analyzed for gamma radionuclides. Gamma radionuclides were below the LLD limits at both indicator and control locations. River Bend Station operations had no significant impact on the environment or public by this waterborne pathway.
Ingestion Sample Results Fish Sample Results Fish samples were collected from one indicator and one control location and analyzed for gamma radionuclides. In 2022, gamma radionuclides were below detectable limits which are consistent with the preoperational monitoring period and operational results. Therefore, based on these measurements, River Bend Station operations had no significant radiological impact upon the environment or public by this ingestion pathway.
4.4.2 Food Products Sample Results The REMP has detected radionuclides prior to 1990 that are attributable to other sources. These include the radioactive plume release due to reactor core degradation at Chernobyl Nuclear Power Plant in 1986 and atmospheric weapons testing.
In 2022, food products samples were collected when available from one indicator and one control location and analyzed for gamma radionuclides. The 2022 levels remained undetectable, as has been the case in previous years. Therefore, based on these measurements, River Bend Station operations had no significant radiological impact upon the environment or public by this ingestion pathway.

Year:2022 Annual Radiological Environmental Operating Report 4.4.3 Milk Sample Results I Page 20 of 44 In 2022 milk samples within five miles (8 km) of River Bend Station were unable to be collected due to the unavailability of milk-producing animals used for human consumption. The River Bend Station Technical Requirements Manual requires collection of milk samples if available commercially within 8 km (5 miles) of the plant.
River Bend Station personnel collected food product samples to monitor the ingestion pathway, as specified in River Bend Station Technical Requirements Manual Table 3.12.1-1, because of milk unavailability. Food product sample results are in section 4.4.2.
4.5 Land Use Census Results The latest land use census (performed in 2022) did not identify any new locations that yielded a calculated dose or dose commitment greater than those currently calculated (see Table 5).
A garden census is not conducted pursuant to the footnote in the TRM (TLCO 3.12.2) that allows the sampling of broad leaf vegetation in the highest calculated average ground-level 0/Q sector (Sector N) near site boundary in lieu of the garden census.
The land use census identified no changes in the new resident census.
There were no changes in the milk cows or food products in 2022.

This was caused by a loss of Grant Substation during a severe thunderstorm event. AR1, AQ1, and AP1 resumed normal operation after power restoration, Power Outage and it was verified that sufficient sample volume was obtained for the period.
Due to an unknown error, AN1 did not resume normal operation and an insufficient sample volume was collected for the period. The digital unit on the sampler was reset and it returned to normal operation with no further issues.
These events will be documented in the 2022 AREOR as sample deviations.
No further actions are needed at this time. (CR-RBS-2022-041 1 5)
During the performance of REMP-3, several air samplers logged power outages during the sample period. The sampler at location AGC logged a 0-minute power outage on 7/22/22 06:09. The samplers at locations AR1, AQ1, AP1, and Power Outage AN1 logged power outages on 7/24/22 1 7:16 for a duration of 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and 20 minutes. These temporary outages were caused by severe weather events. All samples obtained had sufficient sample volume to meet the required LLD for the period. These events will be reported in the 2022 AREOR as sample deviations. No further actions are needed at this time. (CR-RBS-2022-04467)
During the performance of REMP-3 on 09/12/22, it was noted that REMP air samplers at locations AR1, AQ1, AP1, and AN1 experienced a loss of power on 09/01/22 2308. The duration of the power outage was approximately two hours Power Outage and thirty-five minutes. This outage was caused by a loss of Grant Substation power documented previously in CR-RBS-2022-5082. It was verified that sufficient sample volumes were obtained to meet the required LLD. This event will be reported in the 2022 AREOR as a sample deviation. No further actions are needed at this time. (CR-RBS-2022-05300)

The air sampler was operating normally on Power Outage discovery of the outage event, and it was verified that a sufficient sample volume was obtained to meet the required LLD. This condition will be reported in the 2022 AREOR as a sample deviation. No further actions are needed at this time. (CR-RBS-2022-05853)
During the performance of the REMP-2 surveillance, it was identified that the result for one control TLD, #3740 for location TAC, was missing from the vendor processing report. The vendor noted that TLD#3276 was received instead.
Further investigation revealed that the vendor performing the TLD collection/deployment for REMP-1 accidentally confused the 4th Qtr. 2022 TAC TLD with the 1st Qtr. 2023 TLD. This resulted in the 4th Qtr. TLD being redeployed at location TAC and the unexposed TLD was returned to the vendor TLD not for processing in its place. Results for this TLD will not be available during the processed in performance of REMP-2, WO-53021025.
timely manner No other actions are required except documentation by this condition report as an Environmental Deviation to be included in the Annual Radiological Environmental Operating Report for year 2022. Such deviations are permitted in accordance with RBS TRM, Table 3.12.1-1, note (a). (CR-RBS-2023-01696)
NOTE: TLD #3740 was retrieved and processed the following quarter and the reported result is the 90-day normalized dose for the period.

Year: 2022 1.0 Summary Annual Radiological Environmental Operating Report lnterlaboratory Comparison Program Results I
Page 39 of 44 Page 1 of 6 For the Teledyne Brown Engineering (TBE) laboratory, 142 out of 150 analyses performed met the specified acceptance criteria. Eight analyses did not meet the specified acceptance criteria for the following reasons and were addressed through the TBE Corrective Action Program. NOTE: Two analyses (soil for Tc-99 and U-238) that did not meet acceptance criteria was performed for TBE information and is not on the list of required ICP analyses.
Note: The Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) samples are created to mimic conditions found at DOE sites which do not resemble typical environmental samples obtained at commercial nuclear power facilities.
- 1.
The Analytics March 2022 AP Ce-141 result was evaluated as Not Acceptable.
The reported value for Ce-141 was 60.9 pCi and the known result was 42.0 pCi/L (1.45 ratio of reported result vs. known; TBE's internal acceptance range is 0.70 - 1.30). This sample was used as the workgroup duplicate with a result of 45.7 (109% of known) and was also counted on a different detector with a result of 50.9 (121 % of known). This was TBE's first failure for AP Ce-141.
(NCR 22-04)
- 2.
The MAPEP February 2022 Urine U-234 & U-238 results were evaluated as Not Acceptable. TBE's reported values of 0.142 and 0.0254 were above the known upper ranges of 0.0096 and 0.0134 respectively for U-234 and U-238.
These spiked values were below TBE's typical MDC for urine client samples.
The samples were re-prepped using a larger sample aliquot and counted for 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> as opposed to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. The recount results were 0.00732 for U-234 and 0.0119 for U-238 (both within acceptable range). MAPEP urine samples will be flagged to use a larger sample aliquot and counting time than typical client samples. MAPEP did not include any urine cross-check samples in August. (NCR 22-05)
- 3.
The ERA MRAD September 2022 AP Pu-238 was evaluated as Not Acceptable. The reported value was 38.8 pCi and the known result was 29.9 (acceptance range 22.6 - 36.7). The AP filter was cut in half prior to digestion (shared with Fe-55) but should have been complete digested together and aliquoted afterwards like typical client samples. This is the first failure for AP Pu-238. (NCR 22-19)
- 4.
The ERA October 2022 water Uranium result was evaluated as Not Acceptable. The reported value was 10.54 pCi/L and the known was 8.53 (acceptance range 6.60 - 9.88) or 124% of the known (acceptable for TBE QC). The 2-sigma error was 3.2, placing the reported result well within the acceptable range. This sample was used as the workgroup duplicate with a result of 8.2 +/- 2.9 pCi/L (also within the acceptable range). All other QA was reviewed with no anomalies. (NCR 22-20)

The Analytics AP Co-60 result was evaluated as Not Acceptable. The reported value was 207 pCi and the known was 147 (141% of the known). TBE's internal QC acceptance is 70 - 130%. All QA was reviewed with no anomalies.
This sample was used as the workgroup duplicate and counted on a different detector with a result of 167 pCi (114% of the known). This is the first failure for AP Co average result ratio compared to the known is 109%. (NCR 22-
- 21)
- 6.
The MAPEP August 2022 water Tc-99 result was evaluated as Not Acceptable. The reported value was 1.86 +/- 0.414 Bq/L for this "false positive" test. The evaluation of the submitted result to the 3 times the uncertainty indicated a slight positive. This sample was used as the workgroup duplicate with a result of 0.88 +/- 0.374 Bq/L. All QC was reviewed, and no anomalies found. This is the first unacceptable since the resumption of reporting water Tc-99 for the 3rd quarter of 2020. TBE to known ratios have ranged from 94-109% during this time. (NCR 22-22) The Inter-Laboratory Comparison Program provides evidence of "in control" counting systems and methods, and that the laboratories are producing accurate and reliable data.
