| ==SUMMARY==
| |
| | |
| ==1.1 INTRODUCTION==
| |
| | |
| This report summarizes t he 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, 2023 . 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 30 th 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 2023 there were 11 30 samples collected from the atmospheric, aquatic, and terrestrial environments. This includes 161 exposure measurements which were obtained using environmental thermoluminescent dosimeters (TLDs).
| |
| | |
| A small number of issues were encountered in 2023 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 1272 analyses performed on the environmental media samples. T he analyzes of the 2023 Indian Point environmental samples were performed by several laboratories.
| |
| Thermoluminescent dosimeter s were analyzed by Environmental Dosimetry Company (formerly Stanford Associates) of Sterling, MA. Teledyne Brown Engineering, Inc. of Knoxville, TN performed all the remaining ana lyses for 2023. 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 June 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 from two onsite locations in the highest downwind sectors. As allowed for in the ODCM, monthly broad leaf sampling may be used in lie u of a garden census.

| | |
| ==SUMMARY==
| |
| OF RESULTS
| |
| | |
| S amples collected as part of the IPEC REMP continued to contain detectable amounts of naturally -occurrin g and some man- ma de radioactive materials. Offsite ambient radiation measuremen ts using environmenta l TLDs beyond the site boundary ranged between 45 and 64 milli- Roentgens (mR) per year . The range of ambient radiation levels observed with the TLDs is consistent with natural background radiation levels fo r New York.
| |
| | |
| Monitoring of the aquatic envir onm ent in th e area of the s tation indicated the presence of ces ium -137 as a potential station related radioactivit y indicator . Low -levels of cesium -137 were detected in o ne soi l sample at the train ing building location in 2023 . The level s detected were consistent with histori cal findings . No other plant related activity was detec ted in any offsite samples. The pred ominant rad ioactivity for all samples was from non- plant r elated sources, such as fallout from nuc lear weapons tests and natu rally occurring radionuclides.
| |
| | |
| ==1.5 CONCLUSION==
| |
| S
| |
| | |
| The 2023 Radiological Environmental Monitor ing Program for IPEC resulted in the collection an d analysis of over a thousand environmental s am ples and measurements. The data obtained w ere used to determine t h e impact of IPECs operation on the env iron ment and on the general public.
| |
| | |
| An evaluation of dir e ct radiation measurement s , environmental sam ple analyses, and dose calculations demonstrates that all applica ble federal criteria were met. Furthermore, radiat ion levels and resulting doses from station operation wer e a small fraction of those attributed to natural and man- made ba ckground radiation.
| |
| | |
| In summary, the levels of radionuclides in the environment surrounding Ind ian Point were within the historical r anges, i.e., previous levels resulting from natural and anthropogenic sources for the detected r a dionuclides. Further, IP EC operations in 2023 d id not result in exposure to the public greater than the variability of en vironmental background levels.

| 2.1 Overview
| |
| | |
| The Radiological Environmental Monitoring Program (REMP) for 2023 performed by Holtec for the Indian Point Energy Center (IPEC) is discussed in this report. Since the operation of a nuclear power pl ant results in the release of small amounts of radioactivity and low levels of radiation, the Nu clear Regulatory Commissio n (NRC) requires a pr ogram 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 Offsite Dose Calculation Manual, summarizes the results of measurements of r adiation and radioact ivity in the environment in the vicinity of the IPEC and at distant locations during the period January 1 to December 31, 2023.
| |
| | |
| The REMP is used to measure the direct radiation and the airborne and waterborne pathway activity in the vicinity of the Indi an Point site. Direct radiation pathways include radiation from buildings and plant structures, airborne and liqui d 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 air borne 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 sur rounding environment attributed to Indian Point Station opera tions.
| |
| | |
| 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 Po int Station operations.
| |
| | |
| These results are reviewed by IPEC's staff and have been report ed semiannually or annually to the Nuclear Regulatory Commission and others for over 50 years.
| |
| | |
| This repo rt contains a description of the REM P for IPEC and the conduct of that program in 2023 as required by the IPEC ODCM. Also included are summaries and discussions of the results of the 2023 program, trend analyses (where appropriate), comparison to historical results and evaluation of any poten tial impact on the environ ment. Results of the annual land use census, as well as the inter-laboratory comparison program are included, per the ODCM requirement s.

| |
| | |
| Units 1 and 2 are owned by H oltec De commis sioni ng International Indian Point 2, LLC and Unit 3 is owned by Holtec Decommissioning International Indian Point 3 LL C. All thre e units are no longer in operat ion.
| |
| | |
| 2 .3 Program Background
| |
| | |
| Environmental monitoring and surveillance have been conduc ted at Indian Point since 1958, four years pr ior to the st ar t-up of Unit 1. The pre-o perational program was designed and implemented to determine the background radi oactivity and to measure the v ar iations in activity levels from natural and other sources i n the vicinity, as well as fal lout from atmospheric nuclear weapons test s. Thus, as u sed in this report, background levels consist of those resulting from both natur al and anthropogeni c source s o f environmental radioactivity. Accumulation of this background data permi ts the detection and assessment of environmental activity at tributable to plant operations.
| |
| | |
| 2.4 Program Objec tives The current environmental monitoring program is designed to meet t wo primary objectives:
| |
| : 1. To enable the identification and quant ification o f changes in the r adioactivity of the area.
| |
| : 2. To m easure radionuclide conce ntrations in the environment attribut a ble to operations of the Indian Point site.
| |
| | |
| To identify changes in acti vi ty, the environmental sampling schedule requires that analy ses be conducted for specific environm ental media on a regular basis. The radioacti vi ty profile of the environment is esta blished and monitored through routine evaluation of the analyt ical result s obtained.
| |
| | |
| The REMP designates sampling locations for the c ollection of envi ronmental media for analysis. These sampl e locations ar e divided i nto indicator and control locations. I n dicator locations are established near the site, where the presence of env ironmental radioactivity of plant origin is most likely to b e detected. Control locations are established farther away (and upwind/ upstream, w he re applicable) from the site, where t he level would not generally be affected by plant discharges. The use of in dicator and control locations enables the identification of potential s ources of detected radioactivity, thus meeting o ne of the pr ogram objec tives.
| |
| | |
| Verification of expected radionu clide concentrations resulting from effluent releases attributable to the site is another objective of the REMP, which is met by meet ing the two primary program obj ect ive s described above. Ve rifying projected concent ra tions through evaluating REMP data ca n be difficult sinc e the environmental concentrations resulting f r om plant releases are typically too small to be detected . Plant relat ed radionuc lides were detect ed in 2023 in very low levels; however, residual radioac tivity from atmospheri c weapons tests and naturally occurring radioactivity were the predominant sources of radi oactivity in the samples collected. Analysis of the 2023 RE MP sample r esults confirms that environmental concentrations which coul d be attribut ed to radiological eff luents were well below regulatory limits.

| | |
| 3.0 RADIOLOGICAL ENVIRONMENTAL SAMPLING PROGRAM REQUIREMENTS
| |
| | |
| To achieve the objectives of the REMP and ensure com pliance with the ODCM, sampling and an alysis 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/invertebr ate 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 o f detection, which mus t be attained for each medium, sample, or analysis type, and environmental concentrations requiring special report s.
| |
| | |
| 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 2023 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 samplin g locations within ten miles of Indi an Point.
| |
| | |
| 3.2 Sample Analysis
| |
| | |
| The analysis of the 2023 Indian Point envi ronmental samples was performed by two 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 measu red using integrating c alcium sulfate thermoluminescent dosimeters (TLDs), which provide cumulative measurements of radia tion exposure (i.e., total integrated exposures in milli-roentgen, mR) for a given period. The area surrounding the Indian Point site i s divided into 16 compass sectors. Each sector has two TLD sam ple locations. The inner ring is located near the site boundary at appr oximately 1 mile (1.6 km).
| |
| The outer ring is located at approxima tely 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 lo cation 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 a re reported as mR per standard quarter (91 days). The data reported is the average of the two TLDs from each sample site.

| |
| | |
| 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 sam pling 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 filt ers 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 filte rs.
| |
| | |
| 3.3.3 Drinking Water
| |
| | |
| Samples of drink ing water are collected monthly from the Camp Field Reservoir (3.4 miles NE, sample station 7, sample designation Wb1) and New Croto n 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 location s (sampling stations 94 and 95), and one control location (23) on an ann ual 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 v egetation samples are collected from three locations du ring 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 a nal yzed by gamma spectros copy. 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 poi nt exterior to the discharge canal where Hudson River water a nd 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 quar terly for tritium analysis.
| |
| | |
| 3.3.7 Hudson River Bottom Sediment
| |
| | |
| Bottom sediment and bentho s are sampled at four locations: three indicator locations (sampling stations 10, 17, and 28) and one control location (84), along the Hu dson River, once each spr ing and summer; see Figure A-3. These samples are obtained using a
| |
| | |
| Plant: Indian Point Energy Center Year: 2023 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 s amples are collected at three indicator and two contro l locations along the Hudson River. The indicator locations are a t 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 A qua tic 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 veget ation are obta ined depen ding 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 disc harge. The indicator location (downstream sample point ) is designated as sampling station 25 (Ib1), and a second sampli ng 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 collec ted in season or semiannual ly 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 y ear a land use census consisting of milch animal and residence surveys is conducted during the growing season to determine the current utilization of lan d 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 thr ough 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 in the area t hroughout the yea r. An extensi ve 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.

| |
| | |
| A garden census is not required, since the ODCM allows sampling of vegetatio n 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 depo sition rates.
| |
| | |
| 3.4 Statistical Methodology
| |
| | |
| There are several statistical calculation metho dologies used in evaluating the data from the Indian Point REMP. These metho ds include determination of Lower Limits of Detection (LLD) and the Minimum Detectable C oncentration (MDC), and estimation of the mean and associated propagat ed error.
| |
| | |
| 3.4.1 Lower Limit of Dete ction (LLD)
| |
| | |
| The LLD is the smallest concentration of radioactive material in a sample that will yield a net count above system background, and be det ected with 95% probability, with a 5% probability of falsely concludin g that a blank observation represent s a "real" signal.
| |
| | |
| For a particular measurement system (which may include radiochemical separation):
| |
| 2.71+ 3.29 s
| |
| * 1+( T b )
| |
| b LLD t=TsTs E
| |
| * V
| |
| * k* Y
| |
| * e-
| |
| | |
| Where:
| |
| | |
| LLD = The lower limit of detection as defined above (as picocurie per unit mass or volume)
| |
| | |
| Ts = The sample counting time in minu tes
| |
| | |
| 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 s ize (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 u Ci)
| |
| | |
| Y = The fractional radiochemical yield (when applicable)
| |
| | |
| = The radioactive decay constant for the particular radionuclide
| |
| | |
| t = The elapsed time bet ween midpoint of sample collection and time of counting
| |
| | |
| Note: The above LLD formula accounts for differing background and sample count times.
| |
| The Radiological Environmental Mon itoring Program, R EMP, 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.
| |
| | |
| The value of Sb used in the calculation of the LLD for a detection system shall be based on the actual observed varia nce of the ba ckground counting rate or of the counting rate of the
| |
| | |
| Plant: Indian Point Energy Center Year: 2023 Page 18 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT
| |
| | |
| blank samples (as appropriate) rather than on an unverified theoretically predicted variance.
| |
| In calculating t he LLD for a radionuclide determined by gamma ray spectrometry, the background shall inc lude 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 backgr ound count rate i s 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 ana lysis 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 af ter 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 n ot considered positive unles s 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 liste d above (for Tb = Ts, the term 3.29 sb * [(1 + ( Tb / Ts ))1/2] = 4.66 sb).
| |
| | |
| The ODCM requi red lower lim its 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 labora tory'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 le vel for radioact ivity 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 av erages 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 pos itive values t ends to strongly bias the average high, particularly when only a few of the data are measu rably positive. The REMP data show few positive values; thus the corresponding means are biased high.
| |
| Exceptions to this include direct radiation meas ured by TLDs a nd 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 2023. The historical averages are cal culated using o nly the positive values presented for 2011 through 2020. The 2023 average va lues are included in these historic tables for purposes of comparison.

| 4.0 INTERPRETATION AND TRENDS OF RESULTS
| |
| | |
| The 2023 Radiological Environmental Monitoring Program (REMP) was conducted in accordance with Indian Point's Offsite Dose Calculation Manual ODCM. The ODCM contains requirements f or the number and distribution of sampli ng locations, the types of sam ples to be collected, and the types of analyses to be performed fo r measurement of radioactivity.
| |
| | |
| The REMP at Indian Point includes measurements of radioactivity levels in the following environmental pathways.
| |
| | |
| Direct Gam ma 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 an d milch animal census is also part of the REMP.
| |
| | |
| To evaluate the c ontribution of plant operations to environmental radioactivity leve ls, other man- made and natura l sources of environmental radioactivity, as well as the aggregat e of past monitoring data, must be considered. It is not m erely the detection of a radionuclide, but the evaluation of the locat ion, magnitude, sour ce , and history of it s detection that determines its significance. Therefore, we have reported the data collected in 2023 and assessed the significance of the findings.
| |
| | |
| A summary of the results of the 2023 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 locatio ns. Discussions of these results and their evaluations are provided below.
| |
| | |
| The radionucli des de tected in the environment can be grouped into three categories: (1) naturally occurring radionuclides; (2) radionuclides resulting from weapons test ing and other non- plant relat ed, anthropogenic sources; and (3) radionuclides that could be rel ated to plant operations.
| |
| | |
| The environment contains a broad inventory of naturally occurring ra dionuclides 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 radionuclide s constitute the majority of the backgroun d radiation source and thus account for a majority of the annual background dose detected. Since the detected concentrations of these radionuclides were co nsistent at indicator and control locations, and unrel ated to plant operations, their presence is noted only in the data tables and will not be discussed further.
| |
| | |
| The second group of radionuclides detected i n 2023 consists of those resulting from past weapons testing in the earth's atmosphere. The more recent cont amination events resulting from the Chernobyl and Fukushima accidents only indicate d detectable activity shortly after their occurrences (Reference 5). However, weapon s testing in the 1950's and 1960's resulted in a significant atmospheric rad ionuclide inventory, which, in tur n, still contributes to the
| |
| | |
| Plant: Indian Point Energy Center Year: 2023 Page 30 of 121 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT
| |
| | |
| concentrati ons in the ecologic al systems. Although reduced in frequency, atmospheric weapons tes ting continued into the 1980' s. The resultant ra dionuclide i nventory of some radionuclides , a lthough di minis hing with time (e.g., through radioactive de cay and nat ural dis persion processes), re ma ins detectable.
| |
| | |
| In 2023 , the detected radionuclides that may be attributable to past atmo spheric weapons tes ting consist ed of Cs - 137 in s everal media. The l evels detect e d were consistent wit h the historical le vel s of radionuclides resulting from weapons t ests as measured in previous years.
| |
| | |
| The final gr oup of radionuclides det ected by the 2023 REMP comprises those that may b e attributable to current plant operations. Du ring 2023, Cs - 137 w as the only potentially p lant -
| |
| related radionuclide d etected in any environmental samples .
| |
| | |
| H- 3 may be present in the local environment due to either natural occurrence, other manmade sources including nuclear weapons fallout, or as a result of nuclear plant operations. Other s our ces include weapons production and industrial uses where levels are highly dependent on the release rates and distance from the source term.
| |
| | |
| Cs - 137 is ubiquitous in the environment from atmospheric testing deb ris and a lesser amount from the Chernoby l accident . In 2023 , ther e w as one detection of Cs - 137 in a soil sample. I n all cases, t he Cs - 137 concentrations, when detected, were consistent wi th historical val ues.
| |
| | |
| Strontium - 90 (Sr- 90) may also b e present in the environment from atmos pheric testing debri s. Sr - 90 was not d etected in any of the fish, invertebrat e, or sho rel ine soil .
| |
| | |
| I-131 is also produced in fission reactors, but can result from non-plant related anthropoge nic sources , e.g., medical administrations, such as has been noted in previous years. I-131 was not detected in 2023 in aquatic or terrestrial vegetation indicator and control locations.
| |
| | |
| Co-58 and Co-60 are activation/corrosio n 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 th ese radio nuclides is mor e likely the result of recent releases. When significant concentrations of Co-6 0 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 2023 REMP, although they were obser ved in historica l data.

| In the following sections, a summa ry of th e results of the 2023 REMP is presented by sample medi um and the signifi cance of an y positive findings discussed. As previously mentioned, Table B-2 provides an ann ual summary of the following media.
| |
| | |
| 4.1 Direct Radiation
| |
| | |
| The environmental TLDs used to mea sure the direct radiation were TLDs supplied and processed by Environme ntal Dosimetry Company. In 2023, the TLD program produced a consistent picture of ambient background radiation levels in the vicinity of the Indian Point Station. A sum mary of the an nual TLD data is provided in Table B- 2 and all the TLD data are present ed in Tables B-3, B-4 and B-5. TLD sample site DR-40 is the control site for the direct radiation (DR) s eries of measurements.

| | |
| Tabl e B -3 provides the quarterly and annual ave rage re ported doses in mR per standard quarter for each of the d irect radiation sam ple points , D R- 1 through DR - 41. Table B - 4 provides the mean, sta ndard d eviation, minimum an d m aximum v a lues i n mR per year for the years 2014 through 20 22. The 2023 me ans ar e als o presented in Table B- 4. Table B - 5 present s the 2023 TLD data f or the inner r ing and outer ring of TLDs. The table also provides the sector f or each of the DR sampl e po ints.
| |
| | |
| The 2023 me an value for the ind icator direct radiation sample point s wa s 13 .9 mR p er standard quarter - which is consistent with historica l valu es . At thos e l ocations w her e the 2023 mean value was higher than historical me ans , they are within hi stor ical bounds for the respective locatio ns.
| |
| | |
| The DR sample locations are a rranged so that there are two concentric rings of TLD s aro und the Indian P oint sit e. The i n ner ring (DR - 1 to DR - 16) is close to the site boundary. The outer ring ( DR- 17 to DR - 32) has a radius of approx im at ely 5 miles from the three Indian Point units.
| |
| The r esul ts o f the a nnual totals for these two rings of TLDs are provided in Table B-5 . The an nual average for the inner ring was 1 3. 9 mR per standard quarter a nd al so average for the outer ring was 14.1 m R pe r standard quarter. The control location average fo r 2023 w as 1 5. 2 mR per standard quarter.
| |
| | |
| Table C -1 and Figure C -1 pr e sent the 10- year historical a ver a ges for t he inner and outer rings of TLDs . The 2023 av er ages are consist ent w ith the hi storical da ta. The 2023 and previous years' data show that ther e is no measu ra ble direct radiation in the environment due to the operat ion o f the India n P oint site.
| |
| | |
| 4.2 Airborne Particulates and Radioiodine
| |
| | |
| The res ults of the analyses of wee kly air par ticulat e filter samples for gross beta acti vity are presented i n Table B-6 and t he weekly charcoal cartridge analytical results are pr e sented in Table B-7.
| |
| | |
| Gross b eta activity was found in air particulate samples t hroughou t the year at all indi cator and c o ntrol lo ca tions . Th e average gross beta activity for the sev en i nd icat or ai r sample locations was 0.015 pCi/m 3 and the average for the cont rol locatio n w as 0.015 pC i/m 3 as shown in Table B -2. The activities detected were c on sistent for all locations, with no signific ant diff eren ces i n gr oss beta activit y in any sample due to locat ion.
| |
| | |
| T he r esul ts of the gamma spectral analyses (GSA) of the quarterly composi tes of these sam p le s are shown in Table B-8. These quarterly composi te air samples i ndicate that no reactor -related radion u clide s w ere detect ed a nd that only Be -7, a naturally -occu rring ra dionuc lide was present at detectable levels.
| |
| | |
| The mean annual gross b eta concentrati o ns and Cs - 137 co ncentrations in air for the past 10 years are presented in Table C- 2. From th is table and Figure C- 2, it ca n be seen that the average 2023 gross b eta co ncentrat ion was con sistent with historical levels . Cs - 137 has not been detected sinc e 1 987. This is consistent with the trend of decr ea sing ambient Cs - 137 concentrations in recent y ears.
| |
| | |
| From the da ta, it can be seen that no airborne radioact ivity a ttributabl e to the operation of Indian Point was detected in 2023.

| |
| | |
| Re sul ts of the gro ss beta, tritium and gamma spectr os copy analyses of the monthly drinking water samples are i n Ta ble B-9 . Othe r than Gr oss Beta activity consist ent w ith hi st oric al values , no radioactivity was detected in dr inking water samples . This has his torically been t h e case for the radionuclide result s for this me dia . Op eration of the Indian Point units had no det ectable radiological impact on drinking wate r.
| |

Table C -6 contains an hist orical su mmary and Figure C-6 is an illustra tion of the broad leaf vegetation analysis re sul ts . There wer e n o pla nt rel at ed nucl id es detected in the 2 023 samples . The dete ction o f low levels of Cs - 137 has occurred sporadically at indicator locations at r elatively low concentrations m ost likely th e result of previous atm osp heric weapons testing, but C s- 137 has not b een detected in any sample in the last 10 years .
| |
| | |
| 4.6 Hudson R ive r Water Data resulting from analy sis of monthly Hudson River water s am p les f or gamma emitters and quarterly composites of H - 3 are pr esented in Tables B-12.
| |
| | |
| There were no p lant related nuc lides detected in the 2023 samples. Tri tium c ould be dete cte d at levels that are consistent with oc casional historical detection of H -3 related to plant operation. Table C - 3 shows historical H- 3 concentrations at the plant inlet and discharge points. T abl e C -8 contains a co m pa rison of H - 3 d etected at the p la nt di schar ge ( Hudson River Water m ixing poi n t) versus calculated quar terly avera g e efflue nts concentrations . The data in table C -8 provides assurance that the REMP is indeed pro viding verification o f the cal culated radionuc lide concentr a tions result ing from ef fluent releases attributable t o the sit e.

| |
| Cesium - 137 was not detec ted in a ny of the in dicator or control station sam ples . Detection of positive levels of Cs - 137 in river bottom se diment is not unusual. Historical levels of Cs - 137 in bottom sediment samples are shown in table C-9 and figure C -9. This data shows the detection of Cs -137 in bottom sediment s amples at varying levels, in both indicator and control location s, from prior historical releases over the years and from residual weapons testing fallout.

| A census was performed in the v icinity of Indian Point in 2023 . This censu s co nsi st ed of a milch animal and a residence census. Results o f this censu s are presented i n Ta bles B -17 and B -18.
| |
| | |
| The results of the 2023 census wer e g enerally same as t he 2022 census res ults . I n 2021 the pr esence of goats was noted o n a property l ocat ed less t han 5.0 miles of IP EC, discussions with the owner o f the pro pert y indicated t hat the owner no longer owns goats.
| |
| Similar to 2022 , it was noted in 2023 that no animals wer e producin g milk for human consump tio n at this loc a tion o r any other location w ithin 5 miles to IPEC .

| |
| | |
| T he Radio logical Envir on mental Monitoring Program is conducted each year to determine the radiological im pa ct of In dia n Point operations on the enviro nm ent. The prec e ding d isc uss ions of the res ults of the 2023 R EMP reveal that operations at the sta tion did not re sul t in a radiolo gical impact on the environment.
| |
| | |
| The 2023 REMP res ults d emonstrat e the relative co ntributions of di ffe rent radionuclide sources, bot h na tural and anthrop ogenic, to the environmenta l concentrations. The results indicate that the fallout fr om previous at m ospheric weapons testing continues to contribute to d etecti on of Cs - 137 in some env ironmental s amples. Th ere are in frequent detections of plant relate d act ivity i n the environs; howev er, the radiologic al levels are very lo w and a re sig nific a ntly less th an those from natural background and other anthropogenic sourc es.

| HISTORICAL T RENDS
| |
| | |
| The past ten years o f historical data for various ra dionuclides and media are presented both in tabul ar form and graphical form to facilitate the comparison of 2023 data with historical values. Although other samples were taken and analyzed , values were only tabulated and pl otted where positive indications were present.
| |
| | |
| Averaging the positive values in these tables can result in a biased high value, esp ecially, when the radionuclide is detected i n only one or two quarters for the year.
