SUMMARY

Salem and Hope Creek Generating Stations Radiological Environmental Monitoring Program (REMP) was established prior to the station becoming operational to provide information on background radiation present in the area. The goal of SGS/HCGS REMP is to evaluate the impact of the station on the environment. Environmental samples from different media are monitored as part of the program in accordance with specifications detailed in the Offsite Dose Calculation Manual Common REMP (ODCM). The program compares data from indicator locations near the plant, to control locations farther away from the site to assess operation impacts.

The Annual Radioactive Environmental Operating Report (AREOR) provides data obtained through analyses of environmental samples collected at Salem and Hope Creek Generating Station for the reporting period of January 1st through December 31st, 2021. During that time period 1662 analyses were performed on 1306 samples and there was no instance of radioactivity from plant effluents observed in the environment that exceeded any Reporting Levels identified in Salem and Hope Creek Common ODCM Table 3.12-2 [23]. Also, in assessing all the data gathered for this report and comparing these results with preoperational data, it was concluded that the operation of Salem and Hope Creek Generating Stations had no significant radiological impact on the health and safety of the public or on the environment.

2.1 Summary Of

Conclusions:

There was no instance of a plant related radionuclide above baseline detected during this sampling period. Radionuclides identified are summarized in Table 1, 2021 Radiological Environmental Monitoring Program Summary of Results. Natural occurring radionuclides come from minerals and raw materials and exists at exposure levels that are not of concern for radiation protection. These elements are present in the Earth's crust and atmosphere and exists in detectable quantities throughout the world. It is common to detect natural occurring radionuclides in many of the samples collected for REMP. Some examples of naturally occurring radionuclides that are frequently seen in samples are potassium-40, beryllium-7, actinium-228 (present as a decay product of radium-228), and radium-226. Additionally, some relatively long-lived anthropogenic radioisotopes, such as strontium-90 and cesium-137, are also seen in some REMP samples; these radionuclides exist in measurable quantities throughout the world as a result of fallout from historic atmospheric nuclear weapons testing.

Neither cesium-137 nor strontium-90 were detected in any of the indicator or control locations. Detailed information on the exposure of the U.S. population to ionizing radiation can be found in NCRP Report No. 160 [5].

3.0 INTRODUCTION

The Radiological Environmental Monitoring Program (REMP) provides data on measurable levels of radiation and radioactive materials in the site environs. This program also evaluates the relationship between quantities of radioactive materials released from the plant and resultant doses to individuals from principal pathways of exposure. In this capacity, REMP provides a check on the effluent release program and dispersion modeling to ensure that radioactive concentrations in the environment conform to the As Low as Is Reasonably Achievable (ALARA) design objectives of 10 CFR 50, Appendix I. REMP is designed to conform to the Nuclear Regulatory Commission (NRC) Regulatory Guide 4.1 [18], NUREG 1301/1302 [6][7], and the 1979 NRC Branch Technical Position [17].

1 Media is not analyzed in accordance with implemented regulatory program at this facility.

Quality assurance aspects of the sampling program and TLD data collection are conducted in accordance with Regulatory Guides 4.15 [13] and Regulatory Guides 4.13 [22]. REMP also adheres to the requirements of New Jersey, SGS/HCGS Technical Specifications, and the Offsite Dose Calculation Manual Common REMP (ODCM). These governing documents dictate the environmental sampling, sample analysis protocols, data reporting and quality assurance requirements for the environmental monitoring program.

The REMP is based on NRC guidance as reflected in the Site ODCM and establishes sample media, sampling locations, sampling frequency and analytical sensitivity requirements. It also identifies indicator and control locations established for comparison purposes to distinguish plant related radioactivity from naturally occurring or other radioactivity from man-made sources. The environmental monitoring program also verifies the projected and anticipated radionuclide concentrations in the environment and evaluates exposures associated with releases of radionuclides from the Site as described by the ODCM.

This program satisfies the requirements of Section IV.B.2 of Appendix I to 10 CFR 50 and provides surveillance of all appropriate critical exposure pathways to man.

Annual Radiological Environmental Operating Report I YEAR: 2021 I Page 13 of 141 Company: PSEG Nuclear I Plant: Salem and Hope Creek Generating Stations To demonstrate compliance with the requirements, samples of air particulates, air iodine, milk, surface water, ground (well) water, potable (drinking) water, vegetables, fodder crops, fish, crabs, oysters, game, and sediment were collected and analyzed.

External radiation dose measurements were also made in the vicinity of the Site using passive dosimeters. These environmental media were analyzed for one or more of the following: gamma emitting isotopes, tritium (H-3), iodine-131 (I-131), gross alpha, gross beta, direct and immersion dose. Measurements made in the vicinity of the Site were compared to background or control measurements and the preoperational REMP study performed before SGS Unit 1 became operational. The results of these analyses were used to assess the impact on the health and safety of the public or on the environment of Site operations, thereby demonstrating compliance with the applicable Technical Specifications, ODCM Common REMP, and Federal regulations.

The detection capabilities for environmental samples, required by the Site ODCM, were achieved for the Reporting Period. Any exceptions to the program are noted in the Report and the associated PSEG Nuclear corrective action identifier was included in parenthesis.

4.0 SITE DESCRIPTION AND SAMPLE LOCATIONS The Site is located in Lower Alloways Creek Township, Salem County, New Jersey.

SGS consists of two operating pressurized water nuclear power reactors. SGS Unit 1 has an approximate net electrical rating of 1,180 megawatts electric (MWe) and SGS Unit 2 has an approximate net electrical rating of 1,178 MWe. The licensed core thermal power rating for both Units is 3,459 megawatts thermal (MWth). HCGS consists of an operating boiling water nuclear power reactor, which has an approximate net electrical rating of 1,212 MWe. The licensed core thermal power rating is 3,902 MWth.

The Site is located on a man-made peninsula on the east bank of the Delaware River called Artificial Island. The peninsula was created by the deposition of hydraulic fill from dredging operations. The surrounding environment is characterized mainly by the Delaware River Estuary, extensive tidal marshlands, and low-lying meadowlands.

These land types make up a vast majority of the land area within five miles of the Site, with most of the remaining land used for agriculture.

Since 1968, a Radiological Environmental Monitoring Program (REMP) has been conducted at the Site. Starting in December 1972, a more extensive radiological monitoring program was initiated in preparation for the operation of SGS Unit 1. The operational REMP was initiated in December 1976 when SGS Unit 1 achieved criticality.

SGS/HCGS sampling media are selected based on site specific information such as meteorology, receptor locations, and water usage around the plant. Sampling and analysis frequencies are documented in the Offsite Dose Calculation Manual and site procedures. Required sampling, analysis frequencies and location of sample collected are captured in the following tables and figures:

Sector one is divided evenly by the north axis and other sectors are numbered in a clockwise direction, e.g. 1=N, 2=NNE, 3=NE, 4=ENE, 5=E, 6=ESE, 7=SE, 8=SSE, 9=S, 10=SSW, 11=SW, 12=WSW, 13=W, 14=WNW,15=NW, and 16=NNW.

The next digit is a letter which represents the radial distance from the reference point: S=On-site location, X=Site Boundary (SB), A=SB-1 miles off-site, B=1-2 miles off-site, C=2-3 miles off-site, D=3-4 miles off-site, E=4-5 miles off-site, F=5-10 miles off-site, G=10-20 miles off-site and H=>20 miles off-site, Q=Special Interest.

The last number is the station numerical designation within the sector and zone; e.g. 1,2,3,etc For example, the Site # 03E1 would indicate a sample in sector number 3, centered at 45 degrees (north east) with respect to the midpoint between Salem 1 and 2 containments at a radial distance of 4 to 5 miles offsite, (therefore, radial distance E). The number 1 indicates that this is sampling station number 1 in that particular sector.

Annual Radiological Environmental Operating Report I YEAR: 2021 I Page 34 of 141 Company: PSEG Nuclear I Plant: Salem and Hope Creek Generating Stations 9.0 SAMPLING PROGRAM, PROGRAM MODIFICATION AND INTEPRETATION OF RESULTS At most nuclear stations, historical6 data was collected prior to plant operation to determine background radioactivity levels in the environment. Annual data is routinely compared to preoperational and/or 10-year average values to determine if changes in the environs are present. Strict comparison is difficult to make due to fallout from historical nuclear weapon testing. Cesium-137 can be routinely found in environmental samples as a results of above ground nuclear weapons testing. It is important to note, levels of Cs-137 in environment are observed to fluctuate, for example as silt distributions shift due to natural erosion and transport processes, Cs-137 may or may not be observed in sediment samples. Results from samples collected and analyzed during the year, 2021, are described below.

In the following sections, results from direct radiation, air, water, and food products analyzed as part of REMP in 2021 will be discussed. Sampling program descriptions and deviations will also be discussed.

9.1 Environmental Direct Radiation Dosimetry Sample Results Dose is measured as net exposure (field reading less transit reading) normalized over 91 days and relies on comparison of indicator locations to the control location to determine plant impact. During this calendar year 2021, a total of 236 samples were collected and analyzed in accordance with the requirements in Table 2, Radiological Environmental Sampling Program - Exposure Pathway - Direct Radiation. There are different tools used to measure radiation exposure by measuring the intensity of visible light emitted from a sensitive crystal. Thermoluminescent Dosimeter (TLD) or Optical Stimulated Luminance Dosimeter (OSLD) can be used to measure radiation exposure. The SGS/HCGS direct radiation program uses TLDs. Environmental ODCM TLD results are compared by location to historical data to determine if results are within low and high ranges expected for each TLD location as shown in Table 10:

TLD Average Sample Results Direct Radiation Summary.

Ambient radiation levels in the environment were monitored at locations on the Site and in the surrounding areas with pairs of passive dosimeters (PD) supplied and analyzed by Stamford Dosimetry/Environmental Dosimetry Co. Packets containing the PDs were placed in the owner-controlled area, around the Site at various distances, and in each land based meteorological sector. Six were placed in control locations and the balance of measurement locations were placed at areas of interest such as population centers, nearby residences, and schools.

6 Preoperational or 10-year average data.

Annual Radiological Environmental Operating Report I YEAR: 2021 I Page 35 of 141 Company: PSEG Nuclear I Plant: Salem and Hope Creek Generating Stations A total of 59 Immersion Dose Monitor (IDM) locations were established to monitor for direct radiation during 2021, including:

21 on-site locations:

01Q1, 01X2, 02S2a, 02X4, 03X1, 04X1, 05X1, 06X2, 07S1, 08S1, 08S2, 10S1, 11S1, 12S1, 14S2, 15S1, 15S2, 15S3 16S1, 16Q2, and 16X3 27 off-site locations within the 10 mile zone:

04D2, 05D1, 10D1, 14D1, 15D1, 02E1, 03E1, 11E2, 12E1, 13E1, 16E1, 01F1, 02F2, 02F6, 03F2, 04F2, 05F1, 06F1, 07F2, 09F1, 09F2, 10F2, 11F1, 12F1, 13F2, , 14F2, and 15F3 5 areas of interest (population centers, nearby residences, and schools) 02F5, 03F3, 13F3, 13F4 and 16F2 6 control locations beyond 10 miles:

01G3, 03G1, 10G1, 14G1, 16G1, and 03H1.

The PDs at each location are changed and analyzed quarterly.

Two PDs (Panasonic type UD-814) are placed at each location. The laboratory utilizes a Panasonic based system using UD-814 dosimeters that are constructed of three rectangular, lead-shielded (protects against low-energy gamma radiation) teflon wafers, impregnated with 25% calcium sulfate phosphor (CaSO4:Dy) to monitor gamma radiation. Additionally, each PD has one lithium borate (LiBO:Mn) element to monitor beta radiation (which is not used).

In 2019 PSEG implemented American National Standards Institute (ANSI) N13.37-2014 Environmental Dosimetry - Criteria for System Design and Implementation for comparing each PD location dose result to its historical background dose. Per the standard a well-functioning dosimetry system should be able to detect a 5 mrem difference in the quarterly data and a 10 mrem difference in the yearly data above background.

Annual Radiological Environmental Operating Report I YEAR: 2021 I Page 36 of 141 Company: PSEG Nuclear I Plant: Salem and Hope Creek Generating Stations Two on site ISFSI locations 01Q1 and 16Q2 showed measurable dose rates above background as seen in Table 15. The net dose radiation levels as measured by these site boundary locations ranged from 15.7 to 22.7 mrem/Standard Quarter and an annual dose of 85.9 mrem for Locations 01Q1, and 68.7 mrem for Location 16Q2.

Dose to the nearest resident due to direct radiation from ISFSI was calculated to be 0.007 mrem/yr, which is a very small fraction (0.03%) of the 25 mrem/yr limit per 40 CFR 190 and 10 CFR 72.104. Both regulations limit the dose to a real member of the public to 25 mrem in a year to the total body. The calculation was performed using the formula provided in ANSI/HPS N13.37-2014 as follows:

Where:

Gross quarterly dose is the observed field value minus transit and extraneous dose. However, this net dose is not a final net value because the location background has not yet been subtracted. With background subtracted in accordance with ANSI/HPS N13.37-2014, section 7.3.5, all values would be non-detect (ND).

Airborne. During this calendar year 2021, a total of 848 samples (424 particulate filters and 424 iodine cartridges) were collected and analyzed for gross beta, gamma emitters and Iodine - 131. Particulate samplers are used to analyze for gross beta activity following filter change out which occurs weekly. Gamma isotopic analysis is performed on composite samples collected at each location and is analyzed quarterly.

APT (Air Particulate) samples were collected on glass fiber filters with low-volume air samplers sampling at approximately 1.5 SCFM. Air sample volumes were measured with calibrated dry-gas meters.

AIO samples (Air Iodine) were collected from the air by adsorption on triethylene-diamine (TEDA) impregnated charcoal cartridges connected in series after the APT filters.

Annual Radiological Environmental Operating Report I YEAR: 2021 I Page 39 of 141 Company: PSEG Nuclear I Plant: Salem and Hope Creek Generating Stations 9.2.1 Air Particulates APT samples were collected weekly at seven indicator locations (05X1, 06S1, 15S2, 05D1, 16E1, 01F1, and 02F6), one duplicate location (05S2) and one control location (14G1). Each weekly sample collected was analyzed for gross beta by TBE.

Quarterly composites of the weekly samples from each location were analyzed for specific gamma emitters. The duplicate air location sample was shipped to GEL for analysis (Table 16, Table 17, and Table 18).

9.2.2 Gamma Spectroscopy Gamma spectroscopy was performed on each of the 32 quarterly composite samples.

Naturally occurring Be-7 was detected and no other gamma emitters were detected in any of the samples.

Naturally occurring Be-7, attributed to cosmic ray activity in the atmosphere, was detected in all 28 indicator location composites at concentrations ranging from 46E-03 pCi/m3 to 83E-03 pCi/m3 with an average concentration of 65E-03 pCi/m3, and in the four control location composites ranging in concentration from 56E-03 pCi/m3 to 67E-03 pCi/m3 with an average concentration of 61E-03 pCi/m3. The maximum preoperational level detected was 330E-03 pCi/m3 with an average concentration of 109E-03 pCi/m3 (Table 11, Table 16 and RMC-TR-77-03 [21]).

9.2.3 Gross Beta Gross beta activity was detected in all 371 of the indicator location samples at concentrations ranging from 4E-03 pCi/m3 to 42E-03 pCi/m3 with an average concentration of 14E-03 pCi/m3, and in 53 of 53 of the control location samples at concentrations ranging from 5E-03 pCi/m3 to 25E-03 pCi/m3 with an average of 14E-03 pCi/m3. Gross beta activity was less than ten times the yearly mean of control samples. Therefore, per the ODCM gamma isotopic analysis was not required to be performed on the individual samples. The maximum preoperational level detected was 920E-03 pCi/m3 with an average concentration of 74E-03 pCi/m3 (Table 11, Table 17 and RMC-TR-77-03 [21]). See Figure 6.

9.2.4 Air Iodine AIO were collected weekly at seven indicator locations (05X1, 06S1, 15S2, 05D1, 16E1, 01F1, and 02F6), one duplicate location (05S2) and one control location (14G1). The duplicate air location sample was shipped to GEL for analysis. Each sample was analyzed by TBE for I-131, and all 424 samples were less than the MDC for both indicator and control samples during the Reporting Period. The maximum preoperational level detected was 42E-03 pCi/m3 (Table 11, Table 18 and RMC-TR-77-03 [21]).

Annual Radiological Environmental Operating Report I YEAR: 2021 I Page 41 of 141 Company: PSEG Nuclear I Plant: Salem and Hope Creek Generating Stations 9.3 Waterborne Sample Results 9.3.1 Surface Water Surface water samples were collected twice a month at four indicator locations and one control location in the Delaware River Estuary. The two samples for the month were combined to create a single monthly composite sample that was then analyzed.

One location (11A1) is at the outfall area (which is the area potentially impacted by effluents discharged from the Site into the Delaware River), one location is downstream from the outfall area (07E1), and one location is directly west of the outfall area at the mouth of the Appoquinimink River (12B1). Samples were collected upstream in the Delaware River (01F2) and at the mouth of the Chesapeake and Delaware Canal (16F1) the latter being sampled when the flow was from the Canal into the river.

Surface water samples were collected offshore in new polyethylene containers that were rinsed twice with the sample medium prior to collection. The surface water samples were transported to TBE for analysis.

Location 12B1, located directly west of the Site, at the mouth of the Appoquinimink River, serves as the control. 12B1 was chosen as the control location because the physical characteristics of this location more closely resemble those of the outfall area than do those at the farther upstream location (01F2). As discussed in the preoperational summary report, due to its tidal nature, there were flow rate and salinity variations in the Delaware River Estuary. These variations accounted for the differences in K-40 concentrations.

During this calendar year 2021, a total of 60 surface water samples were collected and analyzed in accordance with the requirements of Table 4, Radiological Environmental Sampling Program - Exposure Pathway - Waterborne.

1. Tritium Tritium activity was not detected above the MDC in any of the 48 indicator samples or none of the 12 control location samples.

9.3.4 Sediment Sediment samples were collected semi-annually from six indicator locations and one control location. Location 05A1 was the only shoreline sediment sample location that was directly subjected to tidal fluctuations. The remaining locations were located offshore.

Sediment samples were taken with a bottom grab sampler and frozen in sealed polyethylene containers before being transported in ice chests to TBE. For the river bottom sediment, a marine GPS was used to locate the correct site and the sampling boat was maneuvered over the area until the correct amount of sample was obtained (grabbed) with the sediment dredge.

Location 05A1 shoreline sediment sample (an onsite location) was sampled as follows: A square area, measuring one meter on each side was staked out and then divided into a grid of nine smaller boxes, three per side. A one inch deep scoop from the center of each of the small grids was taken. All the aliquots were combined and the total sample transported in the ice chest to TBE and analyzed for gamma emitters.

Annual values are an average Figure 8, Cesium-137 Activity in Soil 1974 Through 2019 Historically, Cs-137 has been observed in REMP soil samples and attributed to weapons testing. The values observed in these samples are consistent with prior results, and are below the NRCs predicted values of Cs-137 for the New Jersey area soils as a result of fallout from atmospheric weapons testing. Furthermore, the analyzed samples were at concentrations many orders of magnitude above the theoretical impact by plant operation given the Cs-137 concentrations in plant effluents back through 2005.

Additionally, soil is not a formal component of the REMP, nor is it required to be collected as part of the REMP in accordance with the ODCM; it is collected as a REMP Management Audit sample. As such, the ODCM specifies no reportability or LLD thresholds for soil samples. PSEG REMP Implementation procedure, Attachment 1 (Analytical Results Investigation Levels) provides an investigation threshold of 1,000 pCi/kg for Cs-137 in soil and sediment, which is based on the expected concentrations for our region from sources other than plant operation as recognized by the NRC in DOCKET NO.50-219, RFTA NO.99-040.

This evaluation validated suppositions and will appropriately characterize positive sample results obtained in future sampling evolutions as related to atmospheric testing, provided that:

Annual Radiological Environmental Operating Report I YEAR: 2021 I Page 51 of 141 Company: PSEG Nuclear I Plant: Salem and Hope Creek Generating Stations

Soil concentrations are less than 1,000 pCi/kg

Annual gaseous Cs-137 effluents are reviewed and do not show a significant increase

Cs-134 is not detected (Cs-134 is plant related and has a much shorter half-life than Cs-137)

D/Q values continue to be routinely evaluated and are updated as necessary For the above reasons, it can be concluded that the samples are primarily the result of atmospheric testing, with negligible contribution from site operations at PSEG Nuclears three reactors.

Although it has been concluded the Cs-137 in the soil is due to fallout from atmospheric weapons testing, there is essentially no radiological impact to the environment or a member of the public with respect to the annual dose. To demonstrate this, a skin dose calculation was performed for a theoretical person who stood on the soil at location 05F1 for 1,000 hours0 days 0 hours 0 weeks 0 months per year (arbitrary number). This calculation concluded the dose to a member of the public beyond the site boundary would be a mere 2.70E-1 mrem/yr (1.8% of the annual skin dose limit of 15 mrem/yr),

which conforms to 10 CFR 50 Appendix I. Since this activity has been determined to be non-site related, a better comparison is the calculated skin dose against background radiation levels (or approximately 0.1% of the 300 mrem/yr background dose).

No soil samples were collected in 2021. Next scheduled sample will be in 2022.

10.0 LAND USE CENSUS EXPOSURE PATHWAY Annual Land Use Census required by the Offsite Dose Calculation Manual is performed to ensure that changes in the use of areas at or beyond the site boundary are identified and modifications to REMP are made if required by changes in land use. Land use census satisfies the requirements of Section IV.B.3 of Appendix I to 10CFR50. "A land use census shall be conducted and shall identify within a distance of 8 km (5 mi.) the location, in each of the 16 meteorological sectors, of the nearest milk animal, the nearest residence and the nearest garden of greater than 50m2 (500 ft2) producing broad leaf vegetation." Note, per NUREG 1301/1302, Broad leaf vegetation sampling of at least three different kinds of vegetation may be performed at the SITE BOUNDARY in each of two different direction sectors with the highest predicted D/Qs in lieu of the garden census.

A Land Use Census was conducted during the calendar year, 2021, within the growing season to identify changes in land use, receptor locations, and new exposure pathways. The results for the 2021 Land Use Census are listed in Table 12: Land Use Census Results within 5 miles. In summary, the highest D/Q locations for nearest garden, nearest residence and nearest milk animal did not change following the 2021 census.

Sampling and analysis challenges may be experienced due to a multitude of reasons including environmental factors, loss of TLDs, contamination of samples etc. To aid classification of sampling and analysis challenges experienced in 2021, the following three terms are used to describe the issues: Sample Anomalies (SA), Sample Deviation (SD), and Unavailable Samples (US).

Media that experienced downtime (i.e., air samplers or water samplers) during a surveillance period are classified a Sample Deviation. Sample Anomalies are defined as errors that were introduce to a sample once it arrived in the laboratory, errors that prevents the sample from being analyzed as it normally would or may have altered the outcome of the analysis (i.e., cross contamination, human error).

Sample Unavailability are defined as sample collection evolution with no available sample (i.e., food crop, TLD).

All required samples were collected and analyzed as scheduled except for the following:

Annual Radiological Environmental Operating Report YEAR: 2021 Page 101 of 141 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations Attachment 3, Cross Check Intercomparison Program

Annual Radiological Environmental Operating Report YEAR: 2021 Page 102 of 141 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations Participation in cross check intercomparison studies is mandatory for laboratories performing analyses of REMP samples satisfying the requirements in the Offsite Site Dose Calculation Manual. Intercomparison studies provide a consistent and effective means to evaluate the accuracy and precision of analyses performed by a laboratory.

Study results should fall within specified control limits and results that fall outside the control limits are investigated and corrected.

Teledyne Brown Engineering (TBE) and GEL Analytical Services (GEL) participated in the following proficiency testing studies provided by Environmental Resource Associates (ERA), Eckert Ziegler Analytics and DOE Mixed Analyte Performance Evaluation in 2021. The Laboratorys intercomparison program results for 2021 are shown in Table 34 to Table 39.

Teledyne Brown Engineering Summary of Results The TBE Laboratory analyzed Performance Evaluation (PE) samples of air particulate (AP), air iodine, milk, soil, vegetation, and water matrices for various analytes. The PE samples supplied by Analytics Inc., Environmental Resource Associates (ERA) and Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP), were evaluated against the following pre-set acceptance criteria:

A. Analytics Evaluation Criteria Analytics evaluation report provides a ratio of TBEs result and Analytics known value. Since flag values are not assigned by Analytics, TBE evaluates the reported ratios based on internal QC requirements based on the DOE MAPEP criteria.

B. ERA Evaluation Criteria ERAs evaluation report provides an acceptance range for control and warning limits with associated flag values. ERAs acceptance limits are established per the US EPA, National Environmental Laboratory Accreditation Conference (NELAC), state-specific Performance Testing (PT) program requirements or ERAs SOP for the Generation of Performance Acceptance Limits, as applicable. The acceptance limits are either determined by a regression equation specific to each analyte or a fixed percentage limit promulgated under the appropriate regulatory document.

C. DOE Evaluation Criteria MAPEPs evaluation report provides an acceptance range with associated flag values. MAPEP defines three levels of performance:

Acceptable (flag = A) - result within +/- 20% of the reference value

Acceptable with Warning (flag = W) - result falls in the +/- 20% to +/- 30% of the reference value

Not Acceptable (flag = N) - bias is greater than 30% of the reference value Note: The Department of Energy (DOE) Mixed Analyte Performance Evaluation Program (MAPEP) samples are created to mimic conditions found at DOE sites which do not resemble typical environmental samples obtained at commercial nuclear power facilities.

Annual Radiological Environmental Operating Report YEAR: 2021 Page 103 of 141 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations For the TBE laboratory, 146 out of 154 analyses performed met the specified acceptance criteria. Seven analyses did not meet the specified acceptance criteria and were addressed through the TBE Corrective Action Program. NOTE: One analysis (soil for Tc-99) that did not meet acceptance criteria was performed for TBE information and is not on the list of required ICP analyses. A summary is found below:

1. The ERA MRAD March 2021 Water Fe-55 result was evaluated as Not Acceptable. The reported value for Fe-55 was 579 pCi/L and the known result was 275 pCi/L (acceptance range 162 - 400). When reviewing the original sample data, it was found that the carrier yield was 52.6% (lower than typical water samples). Looking at the etched plate that was counted, it appeared that some loss of sample could have occurred. The sample was logged for reanalysis and used as the workgroup duplicate. The results were acceptable at 197 and 221 respectively. Yields were 97.4% and 105.7% and the plated samples were centered with no apparent loss of sample. The loss of sample during plating resulted in a low yield which produced an artificially high sample result. (NCR 21-01)

2. The MAPEP February 2021 AP Gross Alpha result was evaluated as Not Acceptable. The reported value was 0.371 Bq/sample and the known result was 1.77 Bq/sample (acceptance range 0.53 - 3.01). A similar failure had occurred several years prior due to the filter being placed with the wrong side up on the detector. At that time, a small dot was placed on the top of the filter prior to removal from the package to indicate the correct side for counting. The current sample was still in the detector when the result was received (dot side facing the detector). The sample was recounted with a similar result and was flipped and recounted. The flipped result was 0.661 Bq/sample, within the acceptable range. Because TBE cannot rely on receiving correct packaging from the provider, MAPEP AP cross-checks will be counted on both sides going forward. NOTE: The August sample had the same packaging issue (upside down). (NCR 21-02)

3. The MAPEP February 2021 soil Ni-63 was evaluated as Not Acceptable. The reported value was 310 Bq/kg and the known result was 689 (acceptance range 482 - 896). All workgroup QC was reviewed with no anomalies. The analytical procedure had been revised prior to this analysis to eliminate added interferences. The sample yield was

>100%, indicative of incomplete separation from interferences, leading to a lower result.

The procedure was again revised after acceptable results were obtained. (NCR 21-03)

4. The ERA October 2021 water Gross Beta result was evaluated as Not Acceptable. The reported value was 63.0 pCi/L and the known was 55.7 (acceptance range 38.1 - 62.6) or 113% of the known. The 2-sigma error was 6.8, placing the reported result well within the acceptable range. All QA was reviewed with no anomalies. A follow-up Quick Response cross-check was analyzed with a 120% ratio (see item 7). (NCR 21-10)

5. The ERA October 2021 water Tritium result was evaluated as Not Acceptable. The reported value was 13,800 pCi/L and the known was 17,200 (acceptance range 15,000 -

18,900). The 2-sigma error was 1,430, placing the result within the acceptable range.

TBEs internal QC acceptance is 70% - 130%, while ERAs for this sample was 87% -

110%. All QA was reviewed with no anomalies. A Quick Response follow-up cross-check was analyzed with a result of 17,500 pCi/L (known 17,800 pCi/L). (NCR 21-11)

6. The MAPEP August 2021 soil Ni-63 result was evaluated as Not Acceptable. The reported value was 546 Bq/kg and the known result was 1,280 Bq/kg (acceptance range 896 - 1,664). All QC was reviewed and no anomalies found. The procedure revision to

Annual Radiological Environmental Operating Report YEAR: 2021 Page 104 of 141 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations remove added MAPAP interferences was ineffective for this sample. No client soil matrix samples were analyzed for Ni-63 in 2020 or 2021. The root cause investigation is still ongoing at this time. (NCR 21-13)

7. The ERA December 2021 Quick Response water Gross Beta result was evaluated as Not Acceptable. The reported value was 47.6 pCi/L and the known was 39.8 pCi/L or 120% of the known (acceptance range of 26.4 - 47.3). The 2-sigma error was 6.1, placing the reported result well within the acceptable range. All QA was reviewed with no anomalies.

The original sample was recounted on a different detector with a result of 40.3 +/- 6.27 pCi/L. The failure of this sample and the RAD-127 was due to the narrow upper acceptance ranges assigned (119% and 112%) (NCR 21-14)

The Inter-Laboratory Comparison Program provides evidence of in control counting systems and methods, and that the laboratories are producing accurate and reliable data.

All corrective actions are summarized in the Table below.

Corrective Action Request and Report (CARR)

There are two categories of corrective action at GEL. One is corrective action implemented at the analytical and data review level in accordance with the analytical SOP. The other is formal corrective action documented by the Quality Systems Team in accordance with GL-QS-E-002. A formal corrective action is initiated when a nonconformance reoccurs or is so significant that permanent elimination or prevention of the problem is required. Formal corrective action investigations include root cause analysis.

GEL includes quality requirements in most analytical standard operating procedures to ensure that data are reported only if the quality control criteria are met or the quality control measures that did not meet the acceptance criteria are documented. A formal corrective action is implemented according to GL-QS-E-002 for Conducting Corrective/Preventive Action and Identifying Opportunities for Improvement.

Recording and documentation is performed following guidelines stated in GL-QS-E-012 for Client NCR Database Operation.

Any employee at GEL can identify and report a nonconformance and request that corrective action be taken. Any GEL employee can participate on a corrective action team as requested by the QS team or Group Leaders. The steps for conducting corrective action are detailed in GL-QS-E-002. In the event that correctness or validity of the laboratorys test results in doubt, the laboratory will take corrective action. If investigations show that the results have been impacted, affected clients will be informed of the issue in writing within five (5) calendar days of the discovery.

The team consisted of representatives from the affected laboratories. The sample preparation and analytical processes were reviewed. This included review of reagents and standards used in the sample preparation steps, calibration records, process control samples, and interviews with the analysts.

The investigation determined that the laboratory met all quality control criteria specified in each method. Additionally, all internal procedures and policies were performed as required. These failures were tracked through GELs internal non-conformance system.

Root Cause(s):

Radium-226: The laboratory reviewed the data of the original analysis and no anomalies were noted. A review of the sample preparation processes, and data set did not reveal any gross errors or possible contributors to the low bias. It is possible that an unknown systematic error must have occurred during the precipitation steps of the procedure resulting in the low bias.

Radium-228: The Batch data was reviewed and low gravemetric yields were identified. Ra-228 drinking water method includes two gravemetric yields and both yields were lower than normal for this method. It is apparent that the low yields, which are multiplied together to determine the final yield for the analysis, biased the result high. Original reported data was calculated with "typical" method yields obtaining result of 11.9 pCi/L (92% of known value). The low yields were not sample specific with MB and LCS yields being similar to the samples in the batch; therefore, an unknown systematic error must have occurred during the precipitation steps of the procedure that resulted in low yields.

Strontium-89: The result for Strontium-89 was 122% of the known value with the acceptance range limit of 114%.

The Group Leader has reviewed the method to identify the bias. The method LCS trend was reviewed for the method and no anomalies were identified. The calibration used for the analysis was compared to the new calibration performed recently and the original reported data was processed with both calibrations for comparison. Data was comparable. Instrument run logs were reviewed and there was no indication of possible bias from run log. Sr89/90

Both gravemetric batch yields were reviewed and it was noted that the Yttrium yields appeared to be slightly higher than expected for this method. It is possible that the Yttrium yields were biased high due to analyst error during the drying process. The original reported data was processed with typically recovered Yttrium method yields and the Sr-89 value (65.8 pCi/L) was within the acceptance range at 108%.

Root Cause(s):

The results for this analysis were reviewed and it was noted that the result for the in-batch duplicate would have been acceptable recovering at 96% of the known value and met replication criteria. The laboratory investigated the transfer rig that was used to prep the unacceptable sample and noted loose fittings and cracked tubing. These may have contributed to the low bias in the sample preparation. The transfer rig was rebuilt and the other rigs inspected for possible wear issues that may need to be rebuilt or replaced.

The laboratory successfully completed study RAD-126 for Ra-226 by 903.1

Root Cause(s):

MAPEP-21-MaS44: The sample was prepared using standard hot-acid leach per section 7.5 of SW-846 3050B. More rigorous digestions were used in an attempt to increase solubility without success. It is suspected that the low bias in the result is due to an unidentified matrix interferant.

Additionally, all internal procedures and policies were performed as required. These failures were tracked through GELs internal non-conformance system Root Cause:

MAPEP-21-GrF45: Gross Alpha: The data for this analysis has been reviewed and no errors were noted. It was found that the result from the original count for the sample preparation was within the acceptance limits of the study. The sample initially did no t meet replication criteria for the in-batch duplicate and was recounted. The duplicate sample was not recounted during the process.

MAPEP-21-MaS45 (radiological) U-234: The laboratory preparation and counting procedures were evaluated for potential contributors to the high bias of these results. None were noted and the batches met QC criteria for recovery and duplication.

MAPEP-21-MaSF45: Upon review, it is suspected that the bias in the Np result is due to an unidentified matrix interferant. The sample should have been returned to the lab for additional clean up steps. The Sr warning result recovered at 72.5% of the known value. The laboratory evaluated both the prep and instrument processes for possible causes for the low bias. A definitive cause was not determined.

The laboratory chosen for these Quality Control Analyses is General Engineering Laboratories (GEL).

Duplicate samples were obtained for some samples of weekly air iodine and particulates, quarterly air particulate, sediment, broad leaf vegetation, milk, and surface water. These samples were analyzed by GEL as comparison and quality assurance of TBE results. The GEL duplicate analysis results are shown in below.

Agreement between TBE and GEL is based on criteria for accepting measurements in NRC Inspection Procedure 84525.

Air Iodine I-131 was not detected (less than MDC) by both TBE and GEL for all 52 air samples.

Air Particulates Gross beta was detected by GEL and TBE in all 52 of the duplicate weekly APT samples. GEL detects significantly higher gross beta results. The variance between the lab results is due to different calibration energy sources used by each lab.

SUMMARY

Routine quality control (QC) testing was performed for dosimeters issued by the Environmental Dosimetry Company (EDC).

During this annual period 100% (72/72) of the individual dosimeters, evaluated against the EDC internal performance acceptance criteria (high-energy photons only), met the criterion for accuracy and 100% (72/72) met the criterion for precision (Table 40). In addition, 100% (12/12) of the dosimeter sets evaluated against the internal tolerance limits met EDC acceptance criteria (Table 41) and 100% (6/6) of independent testing passed the performance criteria (Table 3). Trending graphs, which evaluate performance statistic for high-energy photon irradiations and co-located stations are given in Appendix A.

One internal assessment was performed in 2021.There were no findings.

1.1 INTRODUCTION

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, and both internal and client directed program assessments.

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. Two programs are used:

1.1.1 QC Program Dosimetry quality control tests are performed on EDC Panasonic 814 Environmental dosimeters. These tests include: (1) the in house testing program coordinated by the EDC QA Officer and (2) independent test perform by EDC clients. In-house tests are performed using six pairs of 814 dosimeters, a pair is reported as an individual result and six pairs are reported as the mean result. The results of these tests are described in this report.

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.

1.1.2 QA Program An internal assessment of dosimetry activities is conducted annually by the Quality Assurance Officer (Reference 1). The purpose of the assessment is to review procedures, results, materials, or components to identify opportunities to improve or enhance processes and/or services.

Annual Radiological Environmental Operating Report YEAR: 2021 Page 134 of 141 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations 2.0 PERFORMANCE EVALUATION CRITERIA 2.1 Acceptance Criteria for Internal Evaluations 2.1.1 Bias For each dosimeter tested, the measure of bias is the percent deviation of the reported result relative to the delivered exposure. The percent deviation relative to the delivered exposure is calculated as follows:

( )

100 where:

Hi = the corresponding reported exposure for the i th dosimeter (i.e., the reported exposure)

Hi = the exposure delivered to the ith irradiated dosimeter (i.e., the delivered exposure) 2.1.2 Mean Bias For each group of test dosimeters, the mean bias is the average percent deviation of the reported result relative to the delivered exposure. The mean percent deviation relative to the delivered exposure is calculated as follows:

( ) 1

( ) 100 ( )

where:

Hi = the corresponding reported exposure for the ith dosimeter (i.e., the reported exposure)

Hi = the exposure delivered to the ith irradiated test dosimeter (i.e., the delivered exposure) n = the number of dosimeters in the test group 2.1.3 Precision For a group of test dosimeters irradiated to a given exposure, the measure of precision is the percent deviation of individual results relative to the mean reported exposure. At least two values are required for the determination of precision. The measure of precision for the ith dosimeter is:

( )

( ) 100

Annual Radiological Environmental Operating Report YEAR: 2021 Page 135 of 141 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations where:

Hi = the reported exposure for the ith dosimeter (i.e., the reported exposure) 1 H= the mean reported exposure, i.e., = ( )

n = the number of dosimeters in the test group 2.1.4 EDC Internal Tolerance Limits All evaluation criteria are taken from the EDC Quality System Manual, (Reference 2).

These criteria are only applied to individual test dosimeters irradiated with high-energy photons (Cs 137) and are as follows for Panasonic Environmental dosimeters: +/- 15%

for bias and +/- 12.8% for precision.

2.2 QC Investigation Criteria and Result Reporting EDC Quality System Manual (Reference 2) specifies when an investigation is required due to a QC analysis that has failed the EDC bias criteria. The criteria are as follows:

1. No investigation is necessary when an individual QC result falls outside the QC performance criteria for accuracy.

2. Investigations are initiated when the mean of a QC processing batch is outside the performance criterion for bias.

2.3 Reporting of Environmental Dosimetry Results to EDC Customers

1. All results are to be reported in a timely fashion.

2. If the QA Officer determines that an investigation is required for a process, the results shall be issued as normal. If the QC results prompting the investigation have a mean bias from the known of greater than +/-20%, the results shall be issued with a note indicating that they may be updated in the future, pending resolution of a QA issue.

3. Environmental dosimetry results do not require updating if the investigation has shown that the mean bias between the original results and the corrected results, based on applicable correction factors from the investigation, does not exceed +/-

20%.

SUMMARY

FOR ISSUANCE PERIOD JANUARY-DECEMBER 2021 3.1 General Discussion Results of performance tests conducted are summarized and discussed in the following sections. Summaries of the performance tests for the reporting period are given in Table 40 through Table 42 and Figure 10 through Figure 13.

Annual Radiological Environmental Operating Report YEAR: 2021 Page 136 of 141 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations Table 40 provides a summary of individual dosimeter results evaluated against the EDC internal acceptance criteria for high-energy photons only. During this period100%

(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. A graphical interpretation is provided in Figure 10 and Figure 11.

Table 41 provides the bias and 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. A graphical interpretation is provided in Figure 12.

Table 42 presents the independent blind spike results for dosimeters processed during this annual period. All results passed the performance acceptance criterion. Figure 4 is a graphical interpretation of Seabrook Station blind co-located station results.

3.2 Result Trending One of the main benefits of performing quality control tests on a routine basis is to identify trends or performance changes. The results of the Panasonic environmental dosimeter performance tests are presented in Figure 10 through Figure 13. The results are evaluated against each of the performance criteria listed in Section II, namely: individual dosimeter accuracy, individual dosimeter precision, and mean bias.
