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 (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, 2020. During that time period 1634 analyses were performed on 1292 samples and there was no instance of radioactivity from plant effluents observed in the environment that exceeded any Reporting Levels identified in SGS ODCM Table 3.12-2 or HCGS ODCM Table 3.12.1-2. 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 one instance of a plant related radionuclide above baseline detected during this sampling period. Tritium was detected in Surface Water but was below reporting levels (Order 80126317-120). Radionuclides identified are summarized in Table 1, 2020 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 concentrations in the environment radioactive effluents 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.

Annual Environmental Operating Report YEAR: 2020 Page 12 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations Figure 1, Potential exposure pathways to Members of the Public due to Plant Operations (1)

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 Offsite Dose Calculation Manual (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 ODCMs 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 Environmental Operating Report YEAR: 2020 Page 13 of 152 Company: PSEG Nuclear 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, ODCMs, and Federal regulations.

The detection capabilities for environmental samples, required by the Site ODCMs, 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:

Although the Delaware River at the location of SGS/HCGS is a brackish water source and is not used for irrigation of food products and so sampling is not required by SGS/HCGS ODCM, samples of vegetables are collected as management audit samples from various locations during harvest. In addition, broad leaf vegetation is collected from various offsite locations as well as being planted & collected onsite (01S1, 07S2, 15S2, 16S1). This is in lieu of having a milk farm within 5 km (3.1 miles) of the Site(1).

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, A=0-1 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.

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 Environmental Operating Report YEAR: 2020 Page 32 of 152 Company: PSEG Nuclear 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, 2020, are described below.

In the following sections, results from direct radiation, air, water, and food products analyzed as part of REMP in 2020 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 2020, a total of 236 samples were collected and analyzed in accordance with the requirements in Table 2, Radiological Environmental Sampling Program - Exposure Pathway - Airborne. 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 8:

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 Environmental Operating Report YEAR: 2020 Page 33 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations A total of 59 Immersion Dose Monitor (IDM) locations were established to monitor for direct radiation during 2020, including:

21 on-site locations:

01S1, 01S2, 02S2a, 02S4, 03S1, 04S1, 05S1, 06S2, 07S1, 08S1, 09S1, 10S1, 11S1, 12S1, 13S1, 14S1, 15S1, 15S2, 16S1, 16S2, and 16S3 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, 08F1, 09F1, 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 Environmental Operating Report YEAR: 2020 Page 34 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations Two on site ISFSI locations 01S1 and 16S2 showed measurable dose rates above background as seen in Table 16, Direct and Immersion Radiation Measurements, 2020. The net dose radiation levels as measured by these site boundary locations ranged from 16.0 to 23.3 mrem/Standard Quarter and an annual dose of 88.8 mrem for Locations 01S1, and 71.7 mrem for Location 16S2.

Dose to the nearest resident due to direct radiation from ISFSI was calculated to be 0.008 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:

D1 = Dose that was measured from TLD Location 16S2 (01S1 was also calculated and had a slightly lower dose)

D2 = Dose that will be extrapolated to Nearest Resident R1 = Distance from the source to the location where D1 was obtained. (Distance from ISFSI to TLD at 16S2)

R2 = Distance from ISFSI to the location that dose will be extrapolated (Nearest Resident)

Annual Environmental Operating Report YEAR: 2020 Page 36 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations Figure 5, TLD Sample Results 9.2 Air Particulate and Radioiodine Sample Results Air particulate filters and charcoal canisters were collected from locations specified in Table 2, Radiological Environmental Sampling Program - Exposure Pathway -

Airborne. During this calendar year 2020, a total of 832 samples (416 particulate filters and 416 iodine cartridges) were collected and analyzed for gross beta, gamma emitters and iodine. 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. Radioiodine (I-131) analysis is performed weekly at the community location.

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 Environmental Operating Report YEAR: 2020 Page 37 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations 9.2.1 Air Particulates APT samples were collected weekly at seven indicator locations (05S1, 07S2, 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 13, Table 14, and Table 15).

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 41E-03 pCi/m3 to 83E-03 pCi/m3 with an average concentration of 61E-03 pCi/m3, and in the four control location composites ranging in concentration from 50E-03 pCi/m3 to 75E-03 pCi/m3 with an average concentration of 62E-03 pCi/m3. The maximum preoperational level detected was 330E-03 pCi/m3 with an average concentration of 109E-03 pCi/m3 (Table 9, Table 13 and RMC-TR-77-03 [21]).

9.2.3 Gross Beta Gross beta activity was detected in all 364 of the indicator location samples at concentrations ranging from 5E-03 pCi/m3 to 27E-03 pCi/m3 with an average concentration of 12E-03 pCi/m3, and in 52 of 52 of the control location samples at concentrations ranging from 6E-03 pCi/m3 to 25E-03 pCi/m3 with an average of 12E-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 9, Table 14 and RMC-TR-77-03 [21]). See Figure 4.

The duplicate air location sample was shipped to GEL for analysis. Each sample was analyzed by TBE for I-131, and all 416 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 9, Table 15 and RMC-TR-77-03 [21]).

Annual Environmental Operating Report YEAR: 2020 Page 39 of 152 Company: PSEG Nuclear 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 (12C1). 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 12C1, located directly west of the Site, at the mouth of the Appoquinimink River, serves as the control. 12C1 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 2020, a total of 60 surface water samples were collected and analyzed in accordance with the requirements of Table 3, Radiological Environmental Sampling Program - Exposure Pathway - Waterborne.

1.

Tritium Tritium activity was detected in 1 of the 48 indicator and none of the 12 control location samples (Order 80126317-120). The occurrence was from a sample collected at location 11A1.

9.3.4 Sediment Sediment samples were collected semi-annually from six indicator locations and one control location. Location 06A1 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 06A1 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.

The maximum preoperational level detected was 1,300 pCi/kg (dry) with an average concentration of 840 pCi/kg (dry). All other gamma emitters were less than the MDC (Table 31 and RMC-TR-77-03 [21]).

9.4 Ingestion Pathway Sample Results 9.4.1 Milk Milk samples (MLK) were taken semi-monthly when cows were on pasture and monthly when cows were not grazing on open pasture, from three indicator locations (13E3, 14F4, 02G3) and one control location (03G1). Animals were considered on pasture from April to November of each year. Samples were collected in new polyethylene containers, sodium bisulfite was added as a sample preservative, and then samples were frozen and transported in ice chests to TBE. Each sample was analyzed for I-131 and gamma emitters.

There is no dairy farm within three miles of the Site, and there is only one dairy farm within five miles (13E3). Therefore, broadleaf vegetation is grown, maintained, and harvested monthly during the growing season.

Locally grown vegetables (FPV) were collected at the time of harvest at six locations (02F9, 03F8, 15F4, 01G1, 02G2, and 03H5); fodder crops (VGT) were sampled at three locations (13E3, 14F4, and 02G3); and broad leaf vegetation (FPL) was sampled at five locations (01S1, 07S2, 15S2, 16S1, and 10D1). The vegetables and fodder samples are additional samples (Management Audit) taken to enhance the radiological monitoring program.

1.

Broadleaf Vegetation Broadleaf vegetation samples were collected since there were no dairy farms operating within the five km (three mile) radius of the Site. The closest dairy farm (13E3) was located in Odessa, DE at 5.0 miles to the West.

All samples were analyzed for gamma emitters and included cabbage, broccoli, hosta, and lambs ear. These samples were obtained from five indicator locations (23 samples) and one control locations (1 samples). The results for these samples are discussed below.

Th-232 was not detected in the control location sample (Table 22).

2.

Vegetables There are no farm products that are irrigated with water in which plant effluents have been discharged. The Delaware River at the location of the Site is brackish and therefore is not used for irrigation.

A variety of food products were sampled on and around the Site; however, the variety was dependent on the farmers preference. These vegetables were collected as Management Audit samples.

All samples were analyzed for gamma emitters and included asparagus, sweet corn, peppers, tomatoes, and peaches. These samples were obtained from seven indicator locations (20 samples). The results for these samples are discussed below.

No plant related gamma emitters were detected above the MDC in any of the indicator or control location vegetable samples.

Naturally occurring Be-7, attributed to cosmic ray activity in the atmosphere, was not detected above the MDC in any of the vegetable samples.

Naturally occurring K-40 was detected in all 20 indicator samples, with concentrations ranging from 1,197 pCi/kg (wet) to 3,076 pCi/kg (wet) with an average concentration of 2,070 pCi/kg (wet). The maximum preoperational level detected was 4,800 pCi/kg (wet) with an average concentration of 2,140 pCi/kg (wet) (Table 23 and RMC-TR 03 [21]).

3.

It was determined that these products could be an element in the food-chain pathway. These fodder crops were collected as Management Audit samples and analyzed for gamma emitters. All three locations from which samples were collected are milk sampling locations.

No plant related gamma emitters were detected above the MDC in any of the indicator or control location fodder crop samples. Naturally occurring Be-7, attributed to cosmic ray activity in the atmosphere, was detected in all of the three indicator samples ranging from 588 pCi/kg (wet) to 1,716 pCi/kg (wet) with an average concentration of 974 pCi/kg (wet).

Naturally occurring K-40 was detected in all 3 samples at concentrations ranging from 2,611 to 3,140 pCi/kg (wet) with an average concentration of 2,840 pCi/kg (wet). No preoperational data was available for comparison (Table 26 and RMC-TR-77-03 [21]).

9.4.4 Soil Soil is sampled every three years and analyzed for gamma emitters. Nine locations were sampled in 2019. These Management Audit samples were collected in areas that have been relatively undisturbed since the last collection in order to determine any change in the radionuclide inventory of the area.

The 2019 samples had naturally occurring K-40 was detected in all nine indicator samples at concentrations ranging from 4,610 to 14,410 pCi/kg (dry) with an average concentration of 9,376 pCi/kg (dry). The maximum preoperational level detected was 24,000 pCi/kg (dry) with an average of 10,000 pCi/kg (dry).

When soil was last collected in 2019, Cs-137 was detected in three of the nine indicator samples at concentrations ranging from 82 to 231 pCi/kg (dry) with an average concentration of 155 pCi/kg (dry). The maximum preoperational level detected was 2,800 pCi/kg (dry) with an average of 800 pCi/kg (dry). See Figure 2 for graphical presentation.

Annual Environmental Operating Report YEAR: 2020 Page 48 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations 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, (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:

CESIUM-137 ACTIVITY IN SOIL 1974 THROUGH 2019 (TRIENNIAL)

Soil is sampled every three years. Last samples were taken in 2019. Annual values are an average

Annual Environmental Operating Report YEAR: 2020 Page 49 of 152 Company: PSEG Nuclear 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 <br />0 hours <br />0 weeks <br />0 months <br /> 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).

Naturally occurring Ra-226 was detected in three of the nine indicator samples at concentrations ranging from 2,090 to 4,079 pCi/kg (dry) with an average concentration of 2,901pCi/kg (dry). The maximum preoperational level detected was 1,500 pCi/kg (dry) with an average of 870 pCi/kg (dry).

Naturally occurring Th-232 was detected in all of the nine indicator samples at concentrations ranging from 387 to 1,007 pCi/kg (dry) with an average concentration of 678 pCi/kg (dry). The maximum preoperational level detected was 1,400 pCi/kg (dry) with an average of 740 pCi/kg (dry).

The analysis of data and review of industry reports indicates that the non-naturally occurring activity found in the soil samples associated with the 2019 triennial REMP soil collection could not be just from Salem and Hope Creek effluents, and likely are from atmospheric weapons testing.

Annual Environmental Operating Report YEAR: 2020 Page 50 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations 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, 2020, within the growing season to identify changes in land use, receptor locations, and new exposure pathways. The results for the 2020 Land Use Census are listed in Table 10: Land Use Census - Nearest Residence within 5 miles.

Annual Environmental Operating Report YEAR: 2020 Page 51 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations 11.0 SAMPLE DEVIATIONS, ANOMALIES AND UNAVAILABILITY Sampling and analysis are performed for media types addressed in the Offsite Dose Calculation Manual. 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 2020, 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:

, Cross Check Intercomparison Program

Annual Environmental Operating Report YEAR: 2020 Page 107 of 152 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 2020. The Laboratorys intercomparison program results for 2020 are shown in Table 32 to Table 37.

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. 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.

Annual Environmental Operating Report YEAR: 2020 Page 108 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations 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.

For the TBE laboratory, 126 out of 133 analyses performed met the specified acceptance criteria. Seven analyses did not meet the specified acceptance criteria for the following reasons and were addressed through the TBE Corrective Action Program. A summary is found below:

1.

The MAPEP February 2020 AP U-233/234 and U-238 results were evaluated as Not Acceptable. The reported value for U-233/234 was 0.0416 +/- 0.0102 Bq/sample and the known result was 0.075 Bq/sample (acceptance range 0.053 - 0.098). The reported value for U-238 was 0.0388 +/- 0.00991 Bq/sample and the known result was 0.078 Bq/sample (acceptance range 0.055 - 0.101). This sample was run as the workgroup duplicate and had RPDs of 10.4% (U-234) and 11.7% (U-238). After the known results were obtained, the sample was relogged. The filter was completely digested with tracer added originally; the R1 results were almost identical. It was concluded that the recorded tracer amount was actually double, causing the results to be skewed. Lab worksheets have been modified to verify actual tracer amount vs. LIMS data. TBE changed vendors for this cross-check to ERA MRAD during the 2nd half of 2020. Results were acceptable at 97.8% for U-234 and 106% for U-238. (NCR 20-13)

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 table below provides the status of CARRs for radiological performance testing during 2020. It has been determined that causes of the unacceptable results did not impact any data reported to our clients.

Fe-55 in soil Root Cause Analysis Upon receipt of the PT report, an investigation was initiated by the Quality Department and a Corrective Action (CARR) team assembled. The team consisted of representatives from the affected areas. 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 the method. Additionally, all internal procedures and policies were performed as required. These failures were tracked through GELs internal non-conformance system.

Iron-55:

The laboratory reviewed the data and noted that the tracer recoveries for this analysis were lower than typical soil tracer recoveries. The lower tracer recoveries contributed to an uncertainty of approximately 25%.

The sample was recounted and recovered at 97% of the known value.

Permanent Corrective/Preventive Actions or Improvements None at this time. The laboratory will continue to monitor the recoveries of these parameters to ensure that there are no continued issues in the processes.

Permanent Corrective/Preventive Actions or Improvements None needed at this time. The laboratory must assume unidentified random errors caused the biases because all quality control criteria were met in the batch.

Subsequent analyses of these isotopes for drinking water were acceptable in other PT samples during the year.

Summary of Results: Split Sample Comparison Program In order to meet the requirement of ODCM 3/4.12.3, INTERLABORATORY COMPARISON PROGRAM, several duplicate environmental samples each year are sent to a second independent laboratory to compare results. 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 period100% (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 1). In addition, 100% (12/12) of the dosimeter sets evaluated against the internal tolerance limits met EDC acceptance criteria (Table 2) 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 and one external audit were performed in 2020.There was one deficiency issued in the external audit.

Annual Environmental Operating Report YEAR: 2020 Page 139 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations I.

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:

A.

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 test 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.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.

B.

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.

II.

PERFORMANCE EVALUATION CRITERIA A.

Acceptance Criteria for Internal Evaluations

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:

i i

i H

H 100 H

where:

i H =

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

Hi = the exposure delivered to the ith irradiated dosimeter (i.e., the delivered exposure)

Annual Environmental Operating Report YEAR: 2020 Page 141 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations A.

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.

B.

Reporting of Environmental Dosimetry Results to EDC Customers All results are to be reported in a timely fashion.

1.

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.

2.

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 2020 A.

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 Tables 1 through 3 and Figures 1 through 4.

Table 1 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 Figures 1 and 2.

Table 2 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 3.

Table 3 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.

Annual Environmental Operating Report YEAR: 2020 Page 142 of 152 Company: PSEG Nuclear Plant: Salem and Hope Creek Generating Stations A.

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 Appendix A. The results are evaluated against each of the performance criteria listed in Section II, namely: individual dosimeter accuracy, individual dosimeter precision, and mean bias.

All of the results presented in Appendix A are plotted sequentially by processing date.

II.

STATUS OF EDC CONDITION REPORTS (CR)

During this annual period, one EDC Condition Report was issued. CR 1-2020 was issued to document the deficiency from the DTE Energy Audit 20-003.

III.

STATUS OF AUDITS/ASSESSMENTS

1.

Internal EDC Internal Quality Assurance Assessment was conducted during the fourth quarter 2020. There were no findings identified.

2.

External DTE Energy Audit 20-003 was conducted on July 28-30, 2020. There was one deficiency identified.

IV.

PROCEDURES AND MANUALS REVISED DURING JANUARY - DECEMBER 2020 Manual 1 was revised on September 28, 2020.

Several procedures were reissued with no changes as part of the 5 year review cycle.

V.

CONCLUSION AND RECOMMENDATIONS The quality control evaluations continue to indicate the dosimetry processing programs at the EDC satisfy the criteria specified in the Quality System Manual. The EDC demonstrated the ability to meet all applicable acceptance criteria.
