SUMMARY
1.1 INTRODUCTION
This report summarizes the results of the Radiological Environmental Monitoring Program (REMP) conducted in the vicinity of Indian Point Energy Center (IPEC) during the period from January 1 to December 31, 2021. The Indian Point site consists of Units 1, 2 and 3, which are operated by Holtec Decommissioning International Unit 1 was retired as a generating facility in 1974, and its reactor is no longer operated. Unit 2 was permanently shutdown on April 30th 2020. Unit 3 ceased operation April 30th 2021.
The REMP has been established to monitor/measure the radiation and radioactivity detectable in the environment that may be attributable to the operation of IPEC. This program, initiated in 1958, includes the collection, analysis, and evaluation of radiological data in order to assess the impact of IPEC on the environment.
1.2 SAMPLING AND ANALYSIS The environmental sampling media collected in the vicinity of IPEC and at distant locations included air particulate filters and charcoal cartridges, soil, drinking water, broad leaf vegetation, river water, shoreline sediment, bottom sediment, aquatic vegetation, fish, and invertebrates.
During 2021 there were 1172 samples collected from the atmospheric, aquatic, and terrestrial environments. This includes 164 exposure measurements which were obtained using environmental thermoluminescent dosimeters (TLDs).
A small number of inadvertent issues were encountered in 2021 in the collection of environmental samples in accordance with the IPEC Offsite Dose Calculation Manual (ODCM). Equipment failures and electrical outages resulted in a small number of instances in which lower than normal sampling volumes were collected at the airborne monitoring stations. A full description of all discrepancies encountered with the environmental monitoring program is presented in the Table B-1 of this report.
There were 1319 analyses performed on the environmental media samples. The analyzes of the 2021 Indian Point environmental samples were performed by several laboratories.
Thermoluminescent dosimeters were analyzed by Environmental Dosimetry Company (formerly Stanford Associates) of Sterling, MA. Teledyne Brown Engineering, Inc. of Knoxville, TN performed all the remaining analyses for 2021. Samples were analyzed as required by the IPEC ODCM.
1.3 LAND USE CENSUS The annual land use census in the vicinity of IPEC was conducted as required by the IPEC ODCM in May through October. No dairy animals whose milk is used for human consumption were identified within 5 miles of the Station during the census. Due to the difficulty of locating individual gardens and determining those having an area greater than 500 square feet, broad leaf sampling was performed. As allowed for in the ODCM, monthly broad leaf sampling may be used in lieu of a garden census.

SUMMARY
OF RESULTS Samples collected as part of the IPEC REMP continued to contain detectable amounts of naturally-occurring and some man-made radioactive materials. Offsite ambient radiation measurements using environmental TLDs beyond the site boundary ranged between 43 and 61 milli-Roentgens (mR) per year. The range of ambient radiation levels observed with the TLDs is consistent with natural background radiation levels for New York.
Monitoring of the aquatic environment in the area of the station indicated the presence of the following potential station related radioactivity, tritium and cesium-137. Tritium was found in river water at the downstream mixing zone of the discharge canal at levels that were expected from routine plant operation, or other sources such as fallout from past weapons testing. Low-levels of cesium-137 were detected in Hudson River bottom sediment samples downstream of the discharge canal, as well as in the Off Verplanck, Lents Cove, and Cold Spring locations.
The levels detected were consistent with historical findings. No other plant related activity was detected in any offsite samples. The predominant radioactivity for all samples was from non-plant related sources, such as fallout from nuclear weapons tests and naturally occurring radionuclides.
1.5 CONCLUSION
S The 2021 Radiological Environmental Monitoring Program for IPEC resulted in the collection and analysis of over a thousand environmental samples and measurements. The data obtained were used to determine the impact of IPECs operation on the environment and on the general public.
In 2021 the only positive detectable plant related activity was three instances of low levels of H-3 detected in river water samples. An evaluation of direct radiation measurements, environmental sample analyses, and dose calculations demonstrates that all applicable federal criteria were met. Furthermore, radiation levels and resulting doses from station operation were a small fraction of those attributed to natural and man-made background radiation.
In summary, the levels of radionuclides in the environment surrounding Indian Point were within the historical ranges, i.e., previous levels resulting from natural and anthropogenic sources for the detected radionuclides. Further, IPEC operations in 2021 did not result in exposure to the public greater than the variability of environmental background levels.

2.0 INTRODUCTION

2.0 INTRODUCTION
2.1 Overview The Radiological Environmental Monitoring Program (REMP) for 2021 performed by Holtec for the Indian Point Energy Center (IPEC) is discussed in this report. Since the operation of a nuclear power plant results in the release of small amounts of radioactivity and low levels of radiation, the Nuclear Regulatory Commission (NRC) requires a program to be established to monitor radiation and radioactivity in the environment (Reference 1). This report, which is submitted to the NRC annually per Indian Point Technical Specifications, summarizes the results of measurements of radiation and radioactivity in the environment in the vicinity of the IPEC and at distant locations during the period January 1 to December 31, 2021.
The REMP is used to measure the direct radiation and the airborne and waterborne pathway activity in the vicinity of the Indian Point site. Direct radiation pathways include radiation from buildings and plant structures, airborne and liquid material that might be released from the plant, cosmic radiation, and the naturally occurring radioactive materials in the ground. Analysis of thermoluminescent dosimeters (TLDs), used to measure direct radiation, indicated that there were no increased radiation levels attributable to plant operations.
The airborne pathway includes measurements of air, drinking water, and broad leaf vegetation samples. The airborne pathway measurements indicated that there was no adverse radiological impact to the surrounding environment attributed to Indian Point Station operations.
The waterborne pathway consists of Hudson River water, fish and invertebrates, aquatic vegetation, bottom sediment, and shoreline sediment. Measurements of the media comprising the waterborne pathway indicated that there was no adverse radiological impact to the surrounding environment attributed to Indian Point Station operations.
These results are reviewed by IPEC's staff and have been reported semiannually or annually to the Nuclear Regulatory Commission and others for over 30 years.
This report contains a description of the REMP for IPEC and the conduct of that program in 2021 as required by the IPEC ODCM. Also included are summaries and discussions of the results of the 2021 program, trend analyses (where appropriate), comparison to historical results and evaluation of any potential impact on the environment. Results of the annual land use census, as well as the inter-laboratory comparison program are included, per the ODCM requirements.
2.2 Site Description The Indian Point site occupies 239 acres on the east bank of the Hudson River on a point of land at Mile Point 42.6. The site is located in the Village of Buchanan, Westchester County, New York. Three nuclear reactors, Indian Point Unit Nos. 1, 2 and 3, and associated buildings occupy approximately 35 acres. Unit 1 began operation in 1962 and was retired as a generating facility in 1974. Units 2 and 3 began operation 1974 and 1978. Indian Point
Plant: Indian Point Energy Center Year: 2021 Page 12 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT Units 1 and 2 are owned by Holtec Decommissioning International Indian Point 2, LLC and Unit 3 is owned by Holtec Decommissioning International Indian Point 3 LLC. All three units are no longer in operation.
2.3 Program Background Environmental monitoring and surveillance have been conducted at Indian Point since 1958, four years prior to the start-up of Unit 1. The pre-operational program was designed and implemented to determine the background radioactivity and to measure the variations in activity levels from natural and other sources in the vicinity, as well as fallout from atmospheric nuclear weapons tests. Thus, as used in this report, background levels consist of those resulting from both natural and anthropogenic sources of environmental radioactivity. Accumulation of this background data permits the detection and assessment of environmental activity attributable to plant operations.
2.4 Program Objectives The current environmental monitoring program is designed to meet two primary objectives:
- 1. To enable the identification and quantification of changes in the radioactivity of the area.
- 2. To measure radionuclide concentrations in the environment attributable to operations of the Indian Point site.
To identify changes in activity, the environmental sampling schedule requires that analyses be conducted for specific environmental media on a regular basis. The radioactivity profile of the environment is established and monitored through routine evaluation of the analytical results obtained.
The REMP designates sampling locations for the collection of environmental media for analysis. These sample locations are divided into indicator and control locations. Indicator locations are established near the site, where the presence of environmental radioactivity of plant origin is most likely to be detected. Control locations are established farther away (and upwind/upstream, where applicable) from the site, where the level would not generally be affected by plant discharges. The use of indicator and control locations enables the identification of potential sources of detected radioactivity, thus meeting one of the program objectives.
Verification of expected radionuclide concentrations resulting from effluent releases attributable to the site is another objective of the REMP, which is met by meeting the two primary program objectives described above. Verifying projected concentrations through evaluating REMP data can be difficult since the environmental concentrations resulting from plant releases are typically too small to be detected. Plant related radionuclides were detected in 2021 in very low levels; however, residual radioactivity from atmospheric weapons tests and naturally occurring radioactivity were the predominant sources of radioactivity in the samples collected. Analysis of the 2021 REMP sample results confirms that environmental concentrations which could be attributed to radiological effluents were well below regulatory limits.

Plant: Indian Point Energy Center Year: 2021 Page 14 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 3.0 RADIOLOGICAL ENVIRONMENTAL SAMPLING PROGRAM REQUIREMENTS To achieve the objectives of the REMP and ensure compliance with the ODCM, sampling and analysis of environmental media are performed as outlined in Table A-1 and described in section 3.3.
3.1 Sample Collection Holtec personnel perform collection of environmental samples for the Indian Point site, with the exception of fish/invertebrate samples. Collection of fish and invertebrate samples is performed by a contracted environmental vendor, Normandeau Associates, Inc.
Environmental media are sampled at the locations specified in Table A-1 and shown in Figures A-1, A-2, and A-3. The samples are analyzed according to criteria established in the ODCM. These requirements include: methods of sample collection; types of sample analysis; minimum sample size required; lower limit of detection, which must be attained for each medium, sample, or analysis type, and environmental concentrations requiring special reports.
Table A-1 provides the sampling station number, location, sector, and distance from Indian Point, sample designation code, and sample type. This table gives the complete listing of sample locations used in the 2021 REMP.
Three maps are provided to show the locations of REMP sampling. Figure A-1 shows the sampling locations within two miles of Indian Point. Figures A-2 and A-3 show the sampling locations within ten miles of Indian Point.
3.2 Sample Analysis The analysis of the 2021 Indian Point environmental samples was performed by several laboratories. Thermoluminescent dosimeters were analyzed by Environmental Dosimetry Company (formerly Stanford Associates) of Sterling, MA. Teledyne Brown Engineering, Inc.
of Knoxville, TN performed all the remaining analyses.
3.3 Sample Collection and Analysis Methodology 3.3.1 Direct Radiation Direct gamma radiation is measured using integrating calcium sulfate thermoluminescent dosimeters (TLDs), which provide cumulative measurements of radiation exposure (i.e., total integrated exposures in milli-roentgen, mR) for a given period. The area surrounding the Indian Point site is divided into 16 compass sectors. Each sector has two TLD sample locations. The inner ring is located near the site boundary at approximately 1 mile (1.6 km).
The outer ring is located at approximately 5 miles (8 km) from the site (6.7- 8.0 km), see Figures A-1 and A-2. Additional TLD locations include a control location at Roseton (20.7 miles north) and eight locations of special interest. In total, there are 41 TLD sample sites, designated DR-1 through DR-41, with two TLDs placed at each site. TLDs are collected and processed on a quarterly basis. The results are reported as mR per standard quarter (91 days). The data reported is the average of the two TLDs from each sample site.
Plant: Indian Point Energy Center Year: 2021 Page 15 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 3.3.2 Airborne Particulates and Radioiodine Air samples were taken at eight locations varying in distance from 0.28 to 20.7 miles (0.5 to 33 km) from the plant. These locations represent one control at sampling station 23 (A5) and seven indicator locations. These indicator locations are at sampling stations 4 (A1), 5 (A4),
27, 29, 94 (A2), 95 (A3), and 108. The locations are shown on Figures A-1, A-2, and A-3.
The air samples are collected continuously by means of fixed air particulate filters followed by in-line charcoal cartridges. Both filters and cartridges are changed on a weekly basis. The filters are analyzed for gross beta and the cartridge samples for radioiodine. In addition, gamma spectroscopy analysis (GSA) is performed on quarterly composites of the air particulate filters.
3.3.3 Drinking Water Samples of drinking water are collected monthly from the Camp Field Reservoir (3.4 miles NE, sample station 7, sample designation Wb1) and New Croton Reservoir (6.3 miles SE, sample station 8); see Figure A-2 and Figure A-3. Each monthly sample is approximately 4 liters and is analyzed for gross beta and gamma-emitting radionuclides. Monthly samples are composited quarterly and analyzed for tritium.
3.3.4 Soil Soil samples are collected from two indicator locations (sampling stations 94 and 95), and one control location (23) on an annual basis; see Figure A-3. They are approximately 2 kg in size and consist of about twenty 2-inch deep cores. The soil samples are analyzed by gamma spectroscopy.
3.3.5 Broad Leaf Vegetation Broad Leaf vegetation samples are collected from three locations during the growing season.
The indicator locations are sampling stations 94 (Ic2) and 95 (Ic1), and the control location is at sampling station 23 (Ic3). See Figures A-1 and A-2. The samples are collected monthly, when available, and analyzed by gamma spectroscopy. These samples consist of at least 1 kg of leafy vegetation and are used in the assessment of the food product and milk ingestion pathways.
3.3.6 Hudson River Water Hudson River water sampling is performed continuously at a point exterior to the discharge canal where Hudson River water and water from the discharge canal mix (sampling station 10, Wa2); see Figure A-1. Samples were also collected continuously at a control station 23 Roseton (Figure A-2 and A-3). An automatic composite sampler is used to take representative samples. On a weekly basis, accumulated samples are taken from both sample points. These weekly river water samples are composited for monthly gamma spectroscopy analysis and quarterly for tritium analysis.
3.3.7 Hudson River Bottom Sediment Bottom sediment and benthos are sampled at four locations: three indicator locations (sampling stations 10, 17, and 28) and one control location (84), along the Hudson River, once each spring and summer; see Figure A-3. These samples are obtained using a
Plant: Indian Point Energy Center Year: 2021 Page 16 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT Peterson grab sampler or similar instrument. The bottom sediment samples are analyzed by gamma spectroscopy.
3.3.8 Hudson River Shoreline Soil Shoreline soil samples are collected at three indicator and two control locations along the Hudson River. The indicator locations are at sampling stations 53 (Wc1), 28, and 17. The control locations are at sampling stations 50 (Wc2) and 84. Figures A-1, A-2, and A-3 show these locations. The samples are gathered at a level above low tide and below high tide and are approximately 2-kg grab samples. These samples are collected at greater than 90 days apart and are analyzed by gamma spectroscopy and for strontium-90.
3.3.9 Hudson River Aquatic Vegetation During the spring and summer, aquatic vegetation samples are collected from the Hudson River at two indicator locations (sampling stations 17 and 28) and one control location (84);
see Figure A-3. Samples of aquatic vegetation are obtained depending on sample availability. These samples are analyzed by gamma spectroscopy.
3.3.10 Fish and Invertebrates Fish and invertebrate samples are obtained from the Hudson River at locations upstream and downstream of the plant discharge. The indicator location (downstream sample point) is designated as sampling station 25 (Ib1), and a second sampling station 107 is located further downstream. The control location (upstream) is at sampling station 23 (Ib2). See Figures A-1 and A-2. These samples are collected in season or semiannually if they are not seasonal.
The fish and invertebrates sampled are analyzed by gamma spectroscopy as well as for strontium-90 and for nickel-63.
3.3.11 Land Use Census In addition to the sampling outlined in Table A-1, there is an environmental surveillance requirement that an annual land use census be performed. Each year a land use census consisting of milch animal and residence surveys is conducted during the growing season to determine the current utilization of land within 5 miles (8 km) of the site. These surveys are used to determine whether there are changes in existing conditions that warrant changing the sampling program. The results of the census are discussed in Section 4.11.
For example, the milch animal census is used to identify animals producing milk for human consumption within 5 miles (8 km) of Indian Point. This census consists of visual field surveys of the areas where a high probability of milch animals exists and confirmation through New York State records or with personnel such as feed suppliers who deal with farm animals and dairy associations.
Visual inspections are made of the 5-mile area around the Indian Point Site during routine sample collections and emergency plan equipment inspections in the area throughout the year. An extensive land survey is conducted of the 5-mile area in an attempt to identify new residential areas, commercial developments and to identify milch animals in pasture.
Plant: Indian Point Energy Center Year: 2021 Page 17 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT A garden census is not required, since the ODCM allows sampling of vegetation in two sectors near the site boundary in lieu of a garden census. The sectors are chosen to be in the pre-dominant wind directions with the highest predicted deposition rates.
3.4 Statistical Methodology There are several statistical calculation methodologies used in evaluating the data from the Indian Point REMP. These methods include determination of Lower Limits of Detection (LLD) and the Minimum Detectable Concentration (MDC), and estimation of the mean and associated propagated error.
3.4.1 Lower Limit of Detection (LLD)
The LLD is the smallest concentration of radioactive material in a sample that will yield a net count above system background, and be detected with 95% probability, with a 5% probability of falsely concluding that a blank observation represents a "real" signal.
For a particular measurement system (which may include radiochemical separation):
2.71
+ 3.29 sb
- 1 + ( T b )
T Ts LLD = s E*V
- k* Y
- e - t Where:
LLD = The lower limit of detection as defined above (as picocurie per unit mass or volume)
Ts = The sample counting time in minutes sb = The standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)
Tb = The background count time in minutes E= The counting efficiency (as counts per transformation)
V= The sample size (in units of mass or volume) k= A constant for the number of transformations per minute per unit of activity (normally, 2.22E+6 dpm per uCi)
Y= The fractional radiochemical yield (when applicable)
= The radioactive decay constant for the particular radionuclide t= The elapsed time between midpoint of sample collection and time of counting Note: The above LLD formula accounts for differing background and sample count times.
The Radiological Environmental Monitoring Program, REMP, may use an LLD formula that assumes equal background and sample count times, when appropriate.
The constants 2.71 and 3.29 and the general LLD equation were derived from References 2 and 3.
Plant: Indian Point Energy Center Year: 2021 Page 18 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT The value of Sb used in the calculation of the LLD for a detection system shall be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance.
In calculating the LLD for a radionuclide determined by gamma ray spectrometry, the background shall include the typical contributions of other radionuclides normally present in the samples. Typical values of E, V, Y, and t shall be used in the calculation. The background count rate is calculated from the background counts that are determined by a separate background count or in the case of gamma ray spectroscopy, from adjacent channels of the energy band of the gamma ray peak used for the quantitative analysis for that radionuclide.
It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement process and not as an a posteriori (after the fact) limit for a particular measurement. To document the post priori (after the fact) measurement statistics, the MDC is calculated after the measurement using the same equation as above.
To handle the a posteriori problem, a decision level must be defined. To minimize the number of false positives, a value is not considered positive unless it is greater than the MDC or 3 times the total standard deviation of the post priori measurement, where MDC is the post priori (after the fact) measurement statistic calculated similar to the LLD equation listed above (for Tb = Ts, the term 3.29 sb * [(1 + ( Tb / Ts ))1/2] = 4.66 sb).
The ODCM required lower limits of detection (LLD) for Indian Point sample analyses are presented in Table A-2. These required lower limits of detection are not the same as the lower limits of detection or critical levels actually achieved by the laboratory. The laboratory's lower limits of detection and critical levels must be equal to or lower than the required levels presented in Table A-2.
Table A-3 provides the reporting level for radioactivity in various media. Sample results that exceed these levels and are due to plant operations require that a special report be submitted to the NRC.
3.4.2 Table Statistics The averages shown in the summary table (Table B-2) are the averages of the positive values in accordance with the NRC's Branch Technical Position (BTP) to Regulatory Guide 4.8 (Reference 4). Samples with "<" values are not included in the averages.
It should be noted that this statistic for the mean using only positive values tends to strongly bias the average high, particularly when only a few of the data are measurably positive. The REMP data show few positive values; thus the corresponding means are biased high.
Exceptions to this include direct radiation measured by TLDs and gross beta radioactivity in air, which show positive monitoring results throughout the year.
The historical data tables contain the annual averages of the positive values for each year for 2011 through 2021. The historical averages are calculated using only the positive values presented for 2011 through 2020. The 2021 average values are included in these historic tables for purposes of comparison.

Other peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Annual Radiological Environmental Operating Report pursuant to the ODCM.
(b) Required detection capabilities for thermoluminescent dosimeters used for environmental measurements are given in Regulatory Guide 4.13.
(c) The LLD is defined as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a real signal.
It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement.
Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations, unavoidable small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable.
In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report pursuant to the ODCM.

Plant: Indian Point Energy Center Year: 2021 Page 29 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 4.0 INTERPRETATION AND TRENDS OF RESULTS The 2021 Radiological Environmental Monitoring Program (REMP) was conducted in accordance with Indian Point's Offsite Dose Calculation Manual ODCM. The ODCM contains requirements for the number and distribution of sampling locations, the types of samples to be collected, and the types of analyses to be performed for measurement of radioactivity.
The REMP at Indian Point includes measurements of radioactivity levels in the following environmental pathways.
Direct Gamma Radiation Drinking Water Broad Leaf Vegetation Hudson River Water Bottom Sediment Shoreline Soil Aquatic Vegetation Fish and Invertebrates Airborne Particulates and Radioiodine Soil An annual land use and milch animal census is also part of the REMP.
To evaluate the contribution of plant operations to environmental radioactivity levels, other man-made and natural sources of environmental radioactivity, as well as the aggregate of past monitoring data, must be considered. It is not merely the detection of a radionuclide, but the evaluation of the location, magnitude, source, and history of its detection that determines its significance. Therefore, we have reported the data collected in 2021 and assessed the significance of the findings.
A summary of the results of the 2021 REMP is presented in Table B-2. This Table lists the mean and range of all positive results obtained for each of the media sampled at ODCM indicator and control locations. Discussions of these results and their evaluations are provided below.
The radionuclides detected in the environment can be grouped into three categories: (1) naturally occurring radionuclides; (2) radionuclides resulting from weapons testing and other non-plant related, anthropogenic sources; and (3) radionuclides that could be related to plant operations.
The environment contains a broad inventory of naturally occurring radionuclides which can be classified as, cosmic ray induced (e.g., Be-7) or geologically derived (e.g., Ra-226 and progeny, Th-228 and progeny, and K-40.) These radionuclides constitute the majority of the background radiation source and thus account for a majority of the annual background dose detected. Since the detected concentrations of these radionuclides were consistent at indicator and control locations, and unrelated to plant operations, their presence is noted only in the data tables and will not be discussed further.
The second group of radionuclides detected in 2021 consists of those resulting from past weapons testing in the earth's atmosphere. The more recent contamination events resulting from the Chernobyl and Fukushima accidents only indicated detectable activity shortly after their occurrences (Reference 5). However, weapons testing in the 1950's and 1960's resulted in a significant atmospheric radionuclide inventory, which, in turn, still contributes to the
Plant: Indian Point Energy Center Year: 2021 Page 30 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT concentrations in the ecological systems. Although reduced in frequency, atmospheric weapons testing continued into the 1980's. The resultant radionuclide inventory of some radionuclides, although diminishing with time (e.g., through radioactive decay and natural dispersion processes), remains detectable.
In 2021, the detected radionuclides that may be attributable to past atmospheric weapons testing consisted of Cs-137 in several media. The levels detected were consistent with the historical levels of radionuclides resulting from weapons tests as measured in previous years.
The final group of radionuclides detected by the 2021 REMP comprises those that may be attributable to current plant operations. During 2021, Cs-137 and Tritium were the only potentially plant-related radionuclides detected in any environmental samples.
H-3 may be present in the local environment due to either natural occurrence, other man-made sources, or as a result of plant operations. Natural occurrence is very low (on the order of approximately 5 pCi/liter - well below typical detectable levels). The major source of H-3 is typically from above ground nuclear weapons testing, in the range of 50 to 150 pCi/liter).
Other sources include weapons production and industrial uses where levels are highly dependent on the release rates and distance from the source term. One such industrial source is nuclear power plant operation. In 2021, very low levels of H-3 were detected in three river water samples.
Cs-137 is ubiquitous in the environment from atmospheric testing debris and a lesser amount from the Chernobyl accident. In 2021, there were six detections of Cs-137 in bottom sediment at indicator and control locations. In all cases, the Cs-137 concentrations, when detected, were consistent with historical values.
Strontium-90 (Sr-90) may also be present in the environment from atmospheric testing debris. Sr-90 was not detected in any of the fish, invertebrate, or shoreline soil.
I-131 is also produced in fission reactors, but can result from non-plant related anthropogenic sources, e.g., medical administrations, such as has been noted in previous years. I-131 was not detected in 2021 in aquatic or terrestrial vegetation indicator and control locations.
Co-58 and Co-60 are activation/corrosion products also related to plant operations. They are produced by neutron activation in the reactor core. Co-58 has a much shorter half-life than Co-60. If Co-58 and Co-60 are concurrently detected in environmental samples, then the source of these radionuclides is more likely the result of recent releases. When significant concentrations of Co-60 are detected but no Co-58, there is an increased likelihood that the Co-60 is due to residual Co-60 from past operations. There was no Co-58 or Co-60 detected in the 2021 REMP, although they were observed in historical data.
In the following sections, a summary of the results of the 2021 REMP is presented by sample medium and the significance of any positive findings discussed. As previously mentioned, Table B-2 provides an annual summary of the following media.
4.1 Direct Radiation The environmental TLDs used to measure the direct radiation were TLDs supplied and processed by Environmental Dosimetry Company. In 2021, the TLD program produced a
Plant: Indian Point Energy Center Year: 2021 Page 31 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT consistent picture of ambient background radiation levels in the vicinity of the Indian Point Station. A summary of the annual TLD data is provided in Table B-2 and all the TLD data are presented in Tables B-3, B-4 and B-5. TLD sample site DR-40 is the control site for the direct radiation (DR) series of measurements.
Table B-3 provides the quarterly and annual average reported doses in mR per standard quarter for each of the direct radiation sample points, DR-1 through DR-41. Table B-4 provides the mean, standard deviation, minimum and maximum values in mR per year for the years 2012 through 2020. The 2021 means are also presented in Table B-4. Table B-5 presents the 2021 TLD data for the inner ring and outer ring of TLDs. The table also provides the sector for each of the DR sample points.
The 2021 mean value for the indicator direct radiation sample points was 13.2 mR per standard quarter - which is consistent with historical values. At those locations where the 2021 mean value was higher than historical means, they are within historical bounds for the respective locations.
The DR sample locations are arranged so that there are two concentric rings of TLDs around the Indian Point site. The inner ring (DR-1 to DR-16) is close to the site boundary. The outer ring (DR-17 to DR-32) has a radius of approximately 5 miles from the three Indian Point units.
The results of the annual totals for these two rings of TLDs are provided in Table B-5. The annual average for the inner ring was 13.2 mR per standard quarter and also average for the outer ring was 13.3 mR per standard quarter. The control location average for 2021 was 14.1 mR per standard quarter.
Table C-1 and Figure C-1 present the 10-year historical averages for the inner and outer rings of TLDs. The 2021 averages are consistent with the historical data. The 2021 and previous years' data show that there is no measurable direct radiation in the environment due to the operation of the Indian Point site.
4.2 Airborne Particulates and Radioiodine The results of the analyses of weekly air particulate filter samples for gross beta activity are presented in Table B-6 and the weekly charcoal cartridge analytical results are presented in Table B-7.
Gross beta activity was found in air particulate samples throughout the year at all indicator and control locations. The average gross beta activity for the seven indicator air sample locations was 0.014 pCi/m3 and the average for the control location was 0.014 pCi/m3. The activities detected were consistent for all locations, with no significant differences in gross beta activity in any sample due to location.
The results of the gamma spectral analyses (GSA) of the quarterly composites of these samples are shown in Table B-8. These quarterly composite air samples indicate that no reactor-related radionuclides were detected and that only Be-7, a naturally-occurring radionuclide was present at detectable levels.
The mean annual gross beta concentrations and Cs-137 concentrations in air for the past 10 years are presented in Table C-2. From this table and Figure C-2, it can be seen that the
Plant: Indian Point Energy Center Year: 2021 Page 32 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT average 2021 gross beta concentration was consistent with historical levels. Cs-137 has not been detected since 1987. This is consistent with the trend of decreasing ambient Cs-137 concentrations in recent years.
From the data, it can be seen that no airborne radioactivity attributable to the operation of Indian Point was detected in 2021.
4.3 Drinking Water Results of the gross beta, tritium and gamma spectroscopy analyses of the monthly drinking water samples are in Table B-9. Other than Gross Beta activity consistent with historical values, no radioactivity was detected in drinking water samples. This has historically been the case for the radionuclide results for this media. Operation of the Indian Point units had no detectable radiological impact on drinking water.
4.4 Soil Table B-10 contains the results of the soil samples for 2021. There were no plant related nuclides detected in the 2021 samples.
4.5 Broad Leaf Vegetation Data from analysis of the 2021 samples are presented in Table B-11. Table C-6 contains an historical summary and Figure C-6 is an illustration of the broad leaf vegetation analysis results. There were no plant related nuclides detected in the 2021 samples. The detection of low levels of Cs-137 has occurred sporadically at indicator locations at relatively low concentrations for the past ten years, most likely the result of previous atmospheric weapons testing.
4.6 Hudson River Water Data resulting from analysis of monthly Hudson River water samples for gamma emitters and quarterly composites of H-3 are presented in Tables B-12.
The only plant related activity detected was H-3; detected at low levels in three indicator samples. The levels are consistent with occasional historical detection of H-3 related to plant operation. Table C-3 shows historical H-3 concentrations at the plant inlet and discharge points. Table C-8 contains a comparison of H-3 detected at the plant discharge (Hudson River Water mixing point) versus calculated quarterly average effluents concentrations. The data in table C-8 provides assurance that the REMP is indeed providing verification of the calculated radionuclide concentrations resulting from effluent releases attributable to the site.
4.7 Hudson River Bottom Sediment Table B-13 contains the results of the analysis of bottom sediment samples for 2021.
Cesium-137 was detected in five of six indicator station samples, and one of two control location samples. Detection of positive levels of Cs-137 in river bottom sediment is not unusual. Cs-137 is often detected in the control location sediments and therefore not likely due to plant releases.
Plant: Indian Point Energy Center Year: 2021 Page 33 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT Historical levels of Cs-137 in bottom sediment samples are shown in table C-9 and figure C-
- 9. This data shows the continued detection of Cs-137 in bottom sediment samples at varying levels, and demonstrates that the levels observed during 2021 sampling are within the range of levels identified in historical samples.
4.8 Hudson River Shoreline Soil Table B-14 contains the results of the gamma spectroscopic and strontium-90 analyses of the shoreline soil samples. Naturally occurring radionuclides were detected in the shoreline soil samples. There were no plant related nuclides detected in the 2021 samples.
An historical look at Cs-137 detected in shoreline soil at indicator and control locations can be viewed in Table C-5 and Figure C-5. Cesium-137 has been present in this media, both at indicator and occasionally at the control location, at a consistent level over the past ten years.
Cesium-134 and Cs-137 are both discharged from the plant in similar quantities. The lack of Cs-134 activity is an indication that the primary source of the Cs-137 in the shoreline soil is legacy contamination from weapons fallout.
Strontium-90 (Sr-90) was not detected in any of the six indicator location samples or any of the control location samples.
4.9 Hudson River Aquatic Vegetation Table B-15 results show no plant related radionuclides were detected in any indicator or control aquatic vegetation samples in 2021. This is consistent with historical findings.
4.10 Fish and Invertebrates Table B-16 contains the results of the analysis of fish and invertebrate samples for 2021.
No plant related radionuclides were detected. This is consistent with historical results which are shown in Table and Figure C-7.
4.11 Land Use Census A census was performed in the vicinity of Indian Point in 2021. This census consisted of a milch animal and a residence census. Results of this census are presented in Tables B-17 and B-18.
The results of the 2021 census were generally same as the 2020 census results. In 2020 the presence of goats was noted on a property located less than 5.0 miles of IPEC, discussions with the owner of the property indicated that the goats did not produce milk for human consumption. Similar to 2020, it was noted in 2021 that no animals were producing milk for human consumption at this location or any other location within 5 miles to IPEC.
However, discussions with the owner for the 2021 land use surveys confirmed that the goats did not produce milk for human consumption and are therefore not milch animals.
The 2021 land use census indicated there were no new residences that were closer in proximity to IPEC.
Plant: Indian Point Energy Center Year: 2021 Page 34 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT The ODCM allows the sampling of broad leaf vegetation in two sectors at the site boundary in lieu of performing a garden census. Analysis results for these two sectors are discussed in Section 4.5 and presented in Table B-11, Table C-6 and Figure C-6.
4.12 Conclusion The Radiological Environmental Monitoring Program is conducted each year to determine the radiological impact of Indian Point operations on the environment. The preceding discussions of the results of the 2021 REMP reveal that operations at the station did not result in an impact on the environment.
The 2021 REMP results demonstrate the relative contributions of different radionuclide sources, both natural and anthropogenic, to the environmental concentrations. The results indicate that the fallout from previous atmospheric weapons testing continues to contribute to detection of Cs-137 in some environmental samples. There are infrequent detections of plant related activity in the environs; however, the radiological levels are very low and are significantly less than those from natural background and other anthropogenic sources.

SUMMARY
Plant: Indian Point Energy Center Year: 2021 Page 36 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 5.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM
SUMMARY
5.1 2021 Annual Radiological Environmental Monitoring Program Summary The results of the 2021 radiological environmental sampling program are presented in Tables B-2 through B-16. Table B-2 is a summary table of the sample results for 2021.
The format of this summary table conforms to the reporting requirements of the ODCM, NRC Regulatory Guide 4.8, and NRC Branch Technical Position to Regulatory Guide 4.8 (Reference 4). In addition, the data obtained from the analysis of samples are provided in Tables B-3 through B-16.
REMP samples were analyzed by various counting methods as appropriate. The methods are; gross beta, gamma spectroscopy analysis, liquid scintillation, radiochemical analysis, and TLD processing. Gamma spectroscopy analysis was performed for gamma emitting nuclides, including the following: Be-7, K-40, Mn-54, Co-58, Co-60, Fe-59, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, I-131, Cs-134, Cs-137, Ba/La-140, Ce-141, Ce-144, Ra-226 and Ac/Th-228. Radiochemical analyses were performed for H-3, Ni-63, Sr-90 and I-131 for specific media and locations as required in the ODCM.
5.2 Land Use Census In accordance with Sections IP2-D3.5.2 and IP3-2.8 of the ODCM, a land use census was conducted to identify the nearest milch animal and the nearest residence. The results of the milch animal and land use census are presented in Tables B-17 and B-18, respectively. In lieu of identifying and sampling the nearest garden of greater than 50 m2, at least three kinds of broad leaf vegetation were sampled near the site boundary in two sectors and at a designated control location (results are presented in Table B-11).
5.3 Sampling Deviations During 2021, environmental sampling was performed for 10 unique media types addressed in the ODCM and for direct radiation. A total of 1172 samples of 1177 scheduled were obtained. Of the scheduled samples, 99.6% were collected and analyzed for the program. Sampling deviations are summarized in Table B-1.

Although other samples were taken and analyzed, values were only tabulated and plotted where positive indications were present.
Averaging the positive values in these tables can result in a biased high value, especially, when the radionuclide is detected in only one or two quarters for the year.

Plant: Indian Point Energy Center Year: 2021 Page 110 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT INTERLABORATORY COMPARISON PROGRAM This section presents the results of the interlaboratory comparison program for the Teledyne Brown Engineering Environmental Services and Environmental Dosimetry Company.
7.1 Program Description - Teledyne Brown Engineering Environmental Services Comparison Programs The Teledyne Brown Engineering Environmental Services participates in several interlaboratory comparison programs. These programs include sample media for which samples are routinely collected and for which comparison samples are commercially available. Participation in these interlaboratory comparison programs ensure that independent checks on the precision and accuracy of the measurement of radioactive material in the environmental samples are performed as part of the Quality Assurance Program for environmental monitoring. To fulfill the requirement for an Interlaboratory Comparison Program, Teledyne Brown Engineering Environmental Services has engaged the following programs:
- Eckert & Ziegler Analytics Environmental Radioactivity Cross Check Program
- Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP)
- Environmental Resource Associates (ERA) Cross Check Program These programs supply sample media as blind samples (typically spikes), which contain certified levels of radioactivity unknown to the analysis laboratory. These samples are prepared and analyzed by the Teledyne Brown Engineering Environmental Services using standard laboratory procedures. Each program issues a statistical summary report of the results. Teledyne Brown Engineering Environmental Services uses predetermined acceptance criteria methodology for evaluating its laboratory performance.
Teledyne Brown Engineering Environmental Services also analyzes laboratory blanks. The analysis of laboratory blanks provides a means to detect and measure radioactive contamination of analytical samples. The analysis of analytical blanks also provides information on the adequacy of background subtraction. Laboratory blank results are analyzed using control charts.
7.2 Acceptance Criteria Each sample result is evaluated to determine the accuracy and precision of the laboratorys analysis result. The sample evaluation method is discussed below.
7.2.1 Analytics Sample Results Evaluation Samples provided by Analytics are evaluated using what is specified as the NRC method.
This method is based on the calculation of the ratio of results reported by the participating laboratory (QC result) to the Vendor Laboratory Known value (reference result).
Plant: Indian Point Energy Center Year: 2021 Page 111 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT An Environmental Laboratory analytical result is evaluated using the following calculation:
The value for the error resolution is calculated.
Error Resolution = Reference Result_______
Reference Results Error (1 sigma)
Using the appropriate row under the Error Resolution column in Table D-2.1, a corresponding Ratio of Agreement interval is given for use in Tables D-3.1, D-3.2, and D-3.3 The value for the ratio is then calculated.
Ratio of agreement = QC Result Reference Result If the value falls within the agreement interval, the result is acceptable.
TABLE D-2.1 Ratio of Agreement ERROR RESOLUTION RATIO OF AGREEMENT
<4 No Comparison 4 to 7 0.5-2.0 8 to 15 0.6-1.66 16 to 50 0.75-1.33 51 to 200 0.8-1.25
>200 0.85-1.18 This acceptance test is generally referred to as the NRC method. The acceptance criteria are contained in Procedure EN-CY-102. The NRC method generally results in an acceptance range of approximately +/- 25% of the Known value when applied to sample results from the Eckert & Ziegler Analytics Interlaboratory Comparison Program. This method is used as the procedurally required assessment method and requires the generation of a deviation from QA/QC program report when results are unacceptable.
7.2.2 ERA and MAPEP Sample Result Evaluation Both these programs supply an acceptance range for evaluating the results.
7.3 Program Results Summary The Interlaboratory Comparison Program numerical results are summarized in the following tables.

Plant: Indian Point Energy Center Year: 2021 Page 116 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 7.4 Environmental TLD Quality Assurance Environmental dosimetry services for the reporting period of January - December, 2021 were provided by the Environmental Dosimetry Company (EDC), Sterling, Massachusetts. The TLD systems at the Environmental Dosimetry Company (EDC) are calibrated and operated to ensure consistent and accurate evaluation of TLDs. The quality of the dosimetric results reported to EDC clients is ensured by in house performance testing and independent performance testing by EDC clients.
The purpose of the dosimetry quality assurance program is to provide performance documentation of the routine processing of EDC dosimeters. Performance testing provides a statistical measure of the bias and precision of dosimetry processing against a reliable standard, which in turn points out any trends or performance changes.
Dosimetry quality control tests are performed on EDC Panasonic 814 Environmental dosimeters. These tests include: (1) the in house testing program conducted by the EDC QA Officer and (2) independent test perform by EDC clients.
Excluded from this report are instrumentation checks. Although instrumentation checks represent an important aspect of the quality assurance program, they are not included as process checks in this report. Instrumentation checks represent between 5-10% of the TLDs processed.
Table D-4.1 provides a summary of individual dosimeter results evaluated against the EDC internal acceptance criteria for high-energy photons (Cs-137) only. The internal acceptance (tolerance) criteria for the Panasonic Environmental dosimeters are: +/- 15%
for bias and +/- 12.8% for precision. During this period, 100% (72/72) of the individual dosimeters, evaluated against these criteria met the tolerance limits for accuracy and 100% (72/72) met the criterion for precision.
Table D-4.2 provides the Bias + Standard deviation results for each group (N=6) of dosimeters evaluated against the internal tolerance criteria. Overall, 100% (12/12) of the dosimeter sets evaluated against the internal tolerance performance criteria met these criteria.
Table D-4.3 presents the independent blind spike results for irradiated dosimeters provided by client utilities during this annual period. All results passed the performance acceptance criterion.
