SUTMMARY During normal operations of a nuclear power generating station there are releases of small amount-is of. radioactive material to the environment. To monitor and determine the effects of these releases a Radiological Environmental- Monitoring Program (REMP) has been established for the environment around Artificial Island where the Salem Generating Stations (SGS) and Hope Creek Generating Station (HCGS) are located. The results of the REMP are published annually, providing a summary and interpretation of the data collected.

PSEG's Maplewood Testing Services (MTS) has been responsible for the collection and analysis of environmental samples during the period of January 1, 2001, through December 31, 2001, and the results are discussed in this report. The REMP for SGS/HCGS was conducted in accordance with the SGS-and HCGS Technical Specifications/Offsite Dose Calculation Manual. The Lower Limit of Detection (LLD) values required by .the Technical Specifications/ODCM were achieved for this reporting period. The objectives of, the program were also met during this period. The data collected assists in demonstrating that SGS and HCGS were operated in compliance with Technical Specifications/ODCM.

Most of the radioactive materials noted in this report are normally present in the environment, either naturally, such as potassium-40, or as a result of non-nuclear generating station activity, such as nuclear bomb testing. Measurements made in the vicinity of SGS/HCGS were compared to background or control measurements and the preoperational REMP study performed before Salem Unit 1 became operational. Samples of air particulates, air iodine, milk, surface, ground and drinking water, vegetables, game, fodder crops, fish, crabs, and sediment were collected and analyzed. External radiation dose measurements were also made in the vicinity of SGS/HCGS using thermoluminescent dosimeters.

From the results obtained, it can be concluded that the levels and fluctuations of radioactivity in environmental samples were as expected for an estuarine environment. No unusual radiological characteristics were observed in the environs of SGS/HCGS during this reporting period. Since these results were comparable to the results obtained during the preoperational phase of the program, and with historical results collected since commercial operation, we can conclude that the operation of SGS and HCGS had no significant impact on the radiological characteristics of the environs of these stations.

To demonstrate compliance with Technical Specifications/ODCM (Sections 3/4.12.1 & 6.8.4.h -1,2,3), samples were analyzed for one or more of the following: gamma emitting isotopes, tritium (H-3), iodine-131 (1-131), gross beta and gross alpha. The results of these analyses were used to assess the environmental impact of SGS and HCGS operations, 1

thereby demonstrating compliance with 'technical Specifications/ODCM (Section 3/4.11) and applicable Federal and State regulations, and to verify the adequacy of radioactive effluent control systems.

The results provided in this report are summarized below:

M There were a total of 1397 analyses on 1121 environmental samples during 2001. Direct radiation dose measurements were made using 196 thermoluminescent dosimeters (TLDs).

• In addition to the detection of naturally-occurring isotopes (i.e. Be-7, K-40, Ra-226 and Th-232) trace levels of Cs-134 and Cs-137 were also detected. The concentrations of these nuclides were well below the Technical Specification reporting limit.

E Dose measurements made with quarterly TLDs at 31 offsite locations around the SGS/HCGS site, averaged 49 millirems for the year 2001.- The average dose measurements at the control locations (background) was 54 millirems for the year. This was comparable to the preoperational phase of the program which had an average of 55 millirems per year for 1973 to 1976.

THE RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Lower All6ways Creek Township, Salem County, New Jersey is the site of Salem (SGS)and Hope Creek (HCGS)' Generating Stations. SGS consists of two operating pressurized water nuclear power reactors.

Salem Unit One has a net rating of; 1133 megawatt electric(MWe) cnd Salem Unit Two has a net rating of"1134 MWe. The licensed core power for both units is 3459 megawatt thermal (MWt). HCGS is a boiling water nuclear power reactor, which has a net rating of 1091 MWe (3339 MWt)

SGS/HCGS are located on a man-made peninsula on the east bank of the Delaware River. It was created by the deposition of hydraulic fill from dredging operations. The environment surrounding SGS/HCGS is characterized mainly by the Delaware River and Bay, extensive tidal marshlands, and low-lying meadowlands. These land types make up approximately 85% of the land area within five miles of the site.

Most of the 'remaining land is used for agriculture [1,21. More specific information on the demograp1-y, hydrology, meteorology, and land use of the area may be found in the Environmental Reports

[1,2], Environmental Statements [3,4], and the Updated Final Safety Analysis Reports for SGS and HCGS [5,6].

Since 1968, a radiological environmental monitoring program (REMP) has been conducted at the SGS/HCGS Site. Starting in December, 1972, more extensive radiological monitoring programs were initiated. The operational REMP was initiated in December, 1976, when Salem Unit 1 achieved criticality. PSEG's Maplewood Testing Services (MTS) has been involved in the REMP since its inception.

MTS is responsible for the collection of all radiological environmental samples and, from 1973 through June, 1983, conducted a quality assurance program in which duplicates of a portion of those samples analyzed by the primary laboratory were also analyzed by MTS.

From January, 1973, through June, 1983, Radiation Management Corporation (RMC) had primary responsibility for the analysis of all samples under the SGS/HCGS REMP and annual reporting of results. RMC reports for the preoperational and operational phase of the program are referenced in this report [7-9]. On July 1, 1983, MTS assumed primary responsibility for the analysis of all samples (except TLDs) and the reporting of results. Teledyne Brown Engineering Environmental Services (TBE), assumed responsibility for third-party QA analyses and TLDs. An additional vendor, Controls for Environmental Pollution Inc. (CEP), was retained to provide third party QA analyses and certain non-routine analyses from May, 1988, until June 1, 1992. Currently, Duke Engineering and Services Environmental Laboratory (DE&SEL) is the third party QA vendor and the laboratory which performs the TLD analyses. MTS reports for the operational phase from 1983 to 2000 are referenced in this report

[10] .

An overview of the 2001 Program is provided in Table 1.

Radioanalytical data from samples collected under this program were compared with results from the preoperational phase. Differences between these periods were examined statistically to determine the effects of static'n operations. This report presents the results from January 1 t ::ough December 31, 2001, for the SGS/HCGS REMP.

OBJECTIVES The objectives of the Operational REMP 'are:

0 To fulfill the requirements of the Radiological Surveillance sections of the Technical. Specifications/ODCM for SGS/HCGS.

N To determine whether any significant increase occurred in the concentration of radionuclides in critical pathways.

• To determine if SGS or HCGS has caused an increase in the radioactive inventory of long-lived radionuclides.

"* To detect any change in ambient gamma radiation levels.

"* To verify that SGS and HCGS operations have no detrimental effects on the health and safety of the public or on the environment.

This report, as required by Section 6.9.1.7 of the Salem Technical Specifications/ODCM and Section 6.9.1.6 of the Hope Creek Technical Specifications/ODCM, summarizes the findings of the 2001 REMP. "

Results of the four-year preoperational program have been summarized for comparison with subsequent operational reports [8]

In order to meet the objectives., an operational REMP was developed.

Samples of various media were selected for monitoring due to the radiological dose impact to human and other organisms. The selection of samples was based on: (1), established critical pathways for the transfer of radionuclides through the environment to man, and, (2), experience gained during the preoperational phase.

Sampling locations were determined based on site meteorology,,

Delaware estuarine hydrology, local demography, and land uses.

Sampling locations were divided into two classes, indicator and control. Indicator stations are those, which are expected to manifest station effects..: Control- samples are collected at locations which are believed to be unaffected by station operations, usually at 15 to 30 kilometers distance. Fluctuations -in the levels of radionuclides and direct radiation at indicator stations are evaluated with respect to analogous fluctuations at control stations. Indicator and control station data are also evaluated relative to preoperational data. Appendix A describes and summarizes, in accordance with .Section 6.9.1.7 of the Salem TS and Section 6.9.1.6 of the Hope Creek TS, the operational program as performed in 2001.

Appendix B describes the coding system which identifies sample type and location. Table B-l lists the sampling stations and the types of samples collected at each station.:: These sampling stations are indicated on Maps B-I and B-2.

DATA INTERPRETATION Results of analyses are grouped according to sample type and presented in Appendix C. All results above the Lower Limit of Detection (LLD) are at a confidence level of 2 sigma. This represents the range of values into which 95% of repeated analyses of the same sample should fall.: As defined in Regulatory Guide 4.8, LLD is the smallest concentration of radioactive material ýin a sample that will yield a net count (above system background) that will be detected with 95% probability, Vith ýonly 5% probability of falsely concluding that a blank observation represents a '"real signal". LLD is normally calculated as 4.66 times the standard deviation of the background counting rate, or of the blank sample, count, as appropriate, divided by counting efficiency, sample size, 2.22 (dpm per picocurie), the radiochemical yield when applicable, the radioactive decay constant and. the- elapsed time between sample collection and time of counting. The Minimum Detectable Concentration (MDC) is defined as the. smallest concentration of radioactive material that can be dotected at a given confidence level. The MDC differs from the LLD in that the MDC- takes into consideration the interference caused by the presence of other nuclides while the LLD does not-.

The grouped data were averaged and standard deviations calculated in accordance with Appendix B of Reference" 16. Thus, the 2 sigma deviations of the averaged data represent sample and not analytical variability. For reporting and calculation of averages, any result occurring at or below the LLD is considered to be at that level.

When a group of data- was composed of 50% or more LLD values, averages were not calculated.

Grab sampling is a useful and acceptable procedure for taking environmental samples of a medium in which the concentration of radionuclides is expected to vary slowly with time or where intermittent sampling is deemed sufficient to'establish the radiological characteristics of the medium. This method, however, is only representative of *the sampled medium for that specific location and instant of time. As a result, variation in the radionuclide concentrations of the samples will normally occur.

Since these variations wil'l tend to counterbalance one another, averages based upon repetitive grab samples is considered valid.

QUALITY ASSURANCE PROGRAM MTS has a quality assurance program designed to ensure confidence in the analytical program. Approximately 20% of the total analytical effort is spent on quality control, including process quality 5

control, instrument quality control, interlaboratory cross-check analyses, and data review.

The quality of the results-obtained by MTS is ensured by the implementation of. the Quality Assurance Program as described in the Maplewood Testing Services Quality Assurance 'Plan [i1 and the Environmental and Chemical Division Procedures Manual. The internal quality control activity of MTS includes the quality control of instrumentation, equipment and reagents; the use of reference standards in calibration, documentation of established procedures and computer programs, and analysis of duplicate and spiked samples.

The external quality control activity is implemented through participation in both the Analytics and the Environmental Resource Associates Interlaboratory Comparison Programs. The result's of these Interlaboratory Comparison Programs are listed in Tables D-1 through D-4 in Appendix D.

RESULTS AND DISCUSSION The analytical results of the 2001 REMP samples are divided into categories based on exposure pathways: atmospheric, direct, terrestrial, and aquatic. The analytical results for the 2001 REMP are summarized in Appendix A. The data for individual samples are presented in Appendix C. The data collected demonstrates that the SGS and HCGS REMP was conducted in compliance with the Technical Specifications/ODCM.

The REMP for the SGS/HCGS Site has historically included samples and analyses not specifically required by these Stations' Technical Specifications/ODCM. MTS continues to collect and analyze some of these samples in order to maintain personnel proficiency in performing these non-routine analyses. These analyses are referenced throughout the report as Management Audit samples. The summary tables in this report include these additional samples and analyses.

ATMOSPHERIC Air particulates were collected on Schleicher-Schuell No. 25 glass fiber filters with low-volume air samplers. Iodine was collected from the air by adsorption on triethylenediamine (TEDA-) impregnated charcoal cartridges connected in series after the air particulate filters. Air sample volumes were measured with calibrated dry-gas meters and were corrected to standard temperature and pressure.

Air Particulates (Tables C-1, C-2)

Air particulate samples were collected weekly, at 6 locations. Each of the 318 samples collected for the year were analyzed for gross beta. Quarterly composites of the weekly samples from each station were analyzed for specific gamma emitters. Total data recovery for the 6 sampling stations in 2001 was 99.91 percent.

6

0 Gross beta activity was detected in 265 of the indicator station samples at concentrations ranging from 8 x 10-3 to 44 x 10-3 pCi/m 3 and in 53 of the control station samples from 11 x I0-3 to 44 x 10-3 pCi/mUh The averages for the indiqator and control station .samples were 231and 25 x i0o3 PCi/m3, respectively. - Theý maximum preoperational

.level detected was 920 x 10v pCi/m3, with an average of 74 x 10-3 pci/m3. Results:from-1980 to current year are plotted on Figure 1 as quarterly-averages. Included along with this plot, for purposes of comparison, is an inset depicting a continuation of this plot from the current year all the wayback to 1973-.

• Gamma spectroscopy, performed on each of the 24 quarterly composite samples analyzed, Aindicated the presence of the naturally-occurring radionuclides Be-7 and K-40. All other gamma emitters searched for were below the LLD.

O Beryllium-7, attributed to cosmic ray activity in the atmosphere, was detected in all 20 indicator station composites that were.analyzed, :at concentrations ranging from 36 x 10-3 to 78 x 10- pCi/mý, with an average of 56 x 10-3 pCi/m',. It was detected in the 4 control station composites ranging from 33 x 10-3 to 66 x 10- 3 pCi/m3, with an average of 53 x 10-3 pCi/M3.. The maximum preoperational level detected was 330 x l:-3 pCi/rn3 , with an average of 109 x 10-3 pCi/m 3 .

o Potassium-40 activity was detected in 13 of the indicator station samples,:with- concentrations ranging from7 x 10-3 tC 14 x 10-3 pCi/m 3 , with an average of 10 x 10-3 pCi/m 3 . K-40 was also detected in 2 control station samples, with concentrations of 9 x 10; and 11 x i0-1 pCi/m 3 . No preoperational data is available for comparison.

Air Iodine (Table C-3)

Iodine in filtered air samples was collected weekly, at 6 locations.

Each of the 318 samples collected for the year was analyzed for I -131.

Iodine-131 was not detected in any of the weekly samples analyzed.

LLD sensitivities for all the stations,- both indicator and control, ranged from *1 x 10-3 to <i0 X 1i0-1 pCi/m3-. The maximum 3

preoperational level detected-was 42 x 10-3 pCi/m .

DIRECT RADIATION Ambient radiation levels in, the environs: were- measured with energy compensated CaSO4 (TI) thermoluminescent dosimeters (TLDs) supplied and read by DE&SEL. Packets containing TLD's for quarterly exposure were placed in the owner controlled area and around the Site at various distances.

7

Direct Radiation (Table C-4)

A total of 49 locations were monitored for direct radiation during 2001, including 12 on-site locations, -31 off-site locations within the 10 mile zone,, and 6 control locations beyond 10 miles. Effort was made to locate TLD's at schools and population centers -in the area.

Five readings for each TLD (ie; 5 elements) at each location were taken in order to obtain a more statistically valid result. For these measurements, the rad is considered equivalent to the rem, in accordance with 10CFR20.1004.

The average dose rate for the 31 quarterly off-site indicator TLDs was 4.1 millirads per standard month, and the average control rate was 4.5 millirads per standard month. The preoperational average for the quarterly TLD readings was 4.4 millirads per standard month.

In Figure 2, the quarterly average radiation levels of the off-site indicator stations versus the control stations, are plotted for the period 1980 through 2001, with an inset graph depicting the current year back to 1973.

TERRESTRIAL Milk samples were taken semi-monthly when cows were on pasture and monthly when cows were not grazing on open pasture. Animals are considered on pasture from April to November of each year. Samples were collected in new polyethylene containers and transported in ice chests with no preservatives added.

A well water sample was collected monthly. Separate. raw and treated potable water samples were composited daily at the City cf Salem water treatment plant. All samples were collected in new polyethylene containers.

Locally grown vegetable and fodder crops were collected at the time of harvest. Such samples were weighed and packed in plastic bags.

Game (muskrat) has been collected annually (time of year dependent on weather conditions, which affect pelt thickness). from local farms after being trapped, stripped of their pelts and gutted. The carcasses were packed in plastic bags and kept chilled in ice chests during transport.

Milk (Table C-5)

Milk samples were collected at 4 local dairy farms (2 farms in NJ and 2 in Delaware). Each sample was analyzed for 1-131 and gamma emitters.

N Iodine-131 was not detected in any of the 80 samples analyzed.

8

LLD sensitivities for both the indicator and the control station samples ranged from <0.1 to <0.4 pCi/L. The maximum preoperational level detected was 65 pCi/L which occurred following a period of atmospheric nuclear weapons tests.

Results from 1980 to 2001 are plotted on Figure 3, with an inset graph depicting the current year back to 1973.,

U Gamma spectroscopy performed on each of the 80 samples indicated the presence of the naturally-occurring radionuclide K-40. All other gamma emitters searched for were below the LLD.

0 Potassium-40 was detected in all 80 samples. Concentrations for the 60 indicator station samples ranged from 1220 to 1460 pCi/L, with an average of 1350 pCi/L. The 20 control station sample concentrations ranged from 1220 to 1390 pCi/L, with an average of 1310 *pCi/L. The maximum preoperational level detected was 2000 pCi/L, with an average of 1437 pCi/L.

Well Water (Ground Water) (Tables C-6, C-7)

Although wells in the vicinity of SGS/HCGS are not directly affected by plant operations, water samples were collected monthly from one farm's well during January through December of the year. Each sample was analyzed for gross alpha; gross beta, tritium, and gamma emitters.

N Gross alpha activity was detected in 9 of the well water samples at concentrations ranging. from 1.2 to 2.6 pCi/L and an average of 2.2 pCi/L. The maximum preoperational level detected was 9.6 pCi/L,. There was no preoperational average determined for this analysis...

"* Gross beta activity was detected in all 12 well water samples.

Concentrations for the samples ranged from 9.8 to 14 pCi/L, with an average of 12 pCi/L. The 2001 gross beta results are comparable with the preoperational -results which ranged from

<2.1 to 38 pCi/L, with an average value of 9 pCi/L.

"[ Tritium activity was not detected in any of the well water samples. The LLD, sensitivities, ranged from <-150 to <180 pCi/L.

The maximum preoperational level detected was 380.:pCi/L.

"* Gamma spectroscopy performed on each of the 12 well water samples indicated the presence of the naturally-occurring radionuclides K-40 and Radium. All other gamma emitters searched for were below the LLD.

0 Radium was deteqted in all 12 of the well water samples at concentrations ranging from 90 to 193 pCi/L with an average of 146 pCi/L. The maximum preoperational level detected was 2.0 pCi/L.

9

These values are similar to those found in the past 11 years. However, as with-the 1989 through 2000 results, they are higher than those tfound in the preoperational program.

The results are most likely due to a procedural change for sample preparation. The change results in less-removal of radon (and its daughter products) from the sample. It is reasonable to conclude that values currently observed are typical for this region.,

o Potassium-40 ,was detected in 4 of the samples at concen trations ranging from 48 to 85 pCi/L and an average of 71 pCi/L. The maximum preoperational level detected was 30 pCi/L.

Potable Water (Drinking Water) (Tables C-8, C-9)

Both raw and treated potable water samples were collected and composited by Salem water treatment plant personnel. Each sample consisted of daily aliquots composited into a -imonthly sample. The raw water source forthis plant is Laurel Lake. and adjacent wells.

Each of the 24 individual samples.was analyzed for gross alpha, gross beta, tritium, iodine-131 and gamma emitters.

• ] Gross alpha activity was detected in 10 raw water samples at concentrations of 0.6 to 1.4 pCi/L and in 7 treated water samples ranging from 0.8 to 1.6 pCi/L. The averages for both raw and treated water samples was 0.9 pCi/L. The maximum pre operational level detected was 2.7 pCi/L.

M Gross beta activity was:detected in all 24 samples at concentrations ranging from 2.7 to 4.7 pCi/L for both the raw and treated water. The average concentration for both raw and treated was 3.4 pCi/L. The maximum preoperational level detected was 9-.0 pCi/L, with an average of 4.2 pCi/L.

"* Tritium activity was not detected in any of the raw and treated water samples. LLD sensitivities ranged from <150 to <180 pCi/L. The maximum preoperational level detected was 350 pCi/L, with an average of 179 pCi/L.

"* Iodine-131 measurements to:a sensitivity of 1.0 pCi/L were performed. Since the receiving water body (Delaware River) is brackish, the water is not used for human consumption.

Drinking water supplies are not affected by discharges from the site. Iodine-131 measurements for all 24 samples were below the LLD sensitivities. The LLD sensitivities ranged from <0.1 to <0.4 pCi/L. *

• Gamma spectroscopy performed on each of the 24 monthly water samples indicated the presence of the naturally-occurring radionuclides K-40 and Radium. All other gamma emitters searched for were below the LLD.

10

o The radionuclide K-40 was detected in 11 of the raw and treated potable waters at concentrations ranging from 26 to 70 pCi/L. The combined average ýfor both raw-and treated

- positive results was 44 pCi/L. There was no preoperational Sdata available for comparison.

o Radium was detected iAn-one potable raw samples and in four of the treated samples at concentrations of 4 to 6.5 pCi/L.

LLD sensitivities for the remaining raw and treated waters

• ranged from <1.6 to <3.5 pCi/L. The maximum preoperational level detected was 1.4 pCi/L. The higher results in the two measurable samples are most likely due to the procedural change for sample preparation, as discussed in the Well Water section.

Vegetables (Table C-10)

Although vegetables- in the region are not irrigated with water into which liquid plant- effluents have been discharged, a- variety of food products grown in-the area for human consumption were sampled at 5 indicator stations (14 samples) and 5 control'stations (15 samples).

The vegetables collected as management audit samples were analyzed for gamma emitters and included asparagus, cabbage, sweet corn, peppers and tomatoes.

Gamma spectroscopy performed on each of the 29 samples indicated the presence of the naturally occurring radionuclides K-40 and Radium.

All other gamma emitters searched for were below the LLD.

Potassium-40 was detected in all 29 samples. Concentrations for the 14 indicator station samples ranged from.1420 to 2570 pCi/kg wet and averaged 2090 pCi/kg-wet. ::Concentrations for the 15 control station samples ranged from 1230 to 2710 pCi/kg-wet, and averaged 2060 pCi/kg-wet. The average concentration detected for all samples, both indicator and control, was 2070 pCi/kg-wet.

The maximum preoperational level detected was 4800 pCi/kg-wet, with an average of 2140 pCi/kg-wet.

Radium was detected in 1 indicator sample (tomato) at a concentration of 16 pCi/kg-wet. It was not detected in any of the control station samples. No preoperational data is available for comparison.

Game (Table. C-II)

Although not required by the SGS or HCGS Technical Specifications/ODCM, samples of muskrats, inhabiting the marshlands surrounding the site, are collected. This game is consumed-by local residents. The samples, when available, are collected from 2 locations once a year as management audit samples and analyzed for gamma emitters.

11

Gamma spectroscopy performed on the flesh indicated the presence of the naturally-occurring radionuclide K-40. All other gamma emitters searched for were below the LLD.

Potassium-40 was detected. in the. indicator station sample at a concentration of 2600 pCi/kgwKet.-:and the control station sample at 2840 pCi/kg-wet. The average. forboth muskrat samples was 2720 pCi/kg-wet. The maximum preoperational level detected was 27000 pCi/kg-wet, with an average*Qof-4400 pCi/kg-wet. .

Fodder Crops (Table C--12)

Although not required by the SGS or HCGS Technical Specifications/ODCM, six samples of crops normally used as cattle feed (silage and soybeans) were collected from three indicator stations (5 samples) and one control station. (1 sample). It was determined that these products may be a significant element in the food-chain pathway. Fodder crops are collected as management audit samples and analyzed for gamma emitters. All of the locations from which samples were collected this year are milk sampling stations.

Gamma spectroscopy performed on each of the 6 samples indicated the presence of the naturally-occurring radionuclides Be-7, K-40 and Radium. All other gamma emitters searched for were below the LLD.

Beryllium-7, attributed to cosmic ray activity in the atmosphere, was detected in the 3 indicator silage samples at concentrations of 210 to 670 pCi/kg-wet. It was detected in the control station silage sample at 350 pCi/kg-wet. The average for all the silage samples was 400 pCi/kg-wet. The maximum preoperational level detected for silage was 4700 pCi/kg-wet, with an average of 2000 pCi/kg-wet. Be-7 was not detected in either of the two indicator soybean samples. LLD sensitivities for the soybean samples were

<30 and <40 pCi/kg-wet. The maximum preoperational level detected for soybean samples was 9300 pCi/kg-dry.

Sediment samples were taken with a bottom grab sampler and frozen in sealed polyethylene containers before being transported in ice chests.

Surface Water (Tables C-14,-C-15, C-16)

Surface water samples were collected monthly at 4 indicator stations and 1 control station in the-Delaware estuary.

One location is at the outfall area (which is the area where liquid radioactive effluents from the Salem Station are allowed to be discharged into the Delaware River), another is downstream from the outfall area, and another is directly west of the outfall area at the mouth of the Appoquinimink River. Two upstream locations are in the Delaware River and at the mouth of the Chesapeake and Delaware Canal, the latter being sampledý when thel flow is from the Canal into the river. Station 12C1, at the mouth of the Appoquinimink River, serves as the operational control. All surface water samples were analyzed monthly for gross beta and gamma emitters.

CONCLUSIONS The Radiological Environmental Monitoring Program for Salem and Hope Creek Generating Stations was conducted- during 2001 in accordance with the SGS and HCGS- Technical Specifications/ODCM. The LLD values required by the Technical Specifications/ODCM were achieved for this reporting period., The, objectives of the program were also met during this period. The. data collected-.assists in demonstrating that SGS and--HCGS .were operated in coifpliance with Technical Specifications/ODCM.

From the results obtained, it can be.concluded that the levels and fluctuations of radioactivity in environmental samples were as expected for an estuarine environment-.: No unusual radiological characteristics, were observed in the environs of SGS/HCGS-during this reporting period. Since these results were comparable to the results obtained during the preoperational phase of the program, which ran from 1973 to 1976, and with historical results collected since commercial operation, we can.'conclude that the operation of the Salem and Hope Creek Stations had no-significant impact on the radiological characteristics of. the environs of that area.

APPENDIX B SAMPLE DESIGNATION AND LOCATIONS 39

APPENDIX B SAMPLE DESIGNATION The PSEG's Maplewood Testing Services identifies samples by a three part code. The first two letters are the program identification code. Because of the proximity of the Salem and Hope Creek Stations a common environmental surveillance program is being conducted. The identification code, "SA", has been applied to Salem and Hope Creek stations. The next three letters are for the media sampled.

AIO = Air Iodine IDM Immersion Dose (TLD)

APT = Air Particulate MLK Milk ECH = Hard Shell Blue Crab PWR Potable Water (Raw)

ESF = Edible Fish PWT Potable Water (Treated)

ESS = Sediment SOL Soil FPL = Green Leafy Vegetables SWA Surface Water FPV = Vegetables (Various) VGT Fodder Crops (Various)

GAM = Game (Muskrat) WWA Well Water The last four symbols are a location code based on direction and distance from a standard reference point. Of these, the first two represent each of the sixteen angular sectors of 22.5 degrees centered about the reactor site. Sector one is divided evenly by the north axis and other sectors are numbered in a clockwise direction; e.g., 2=NNE, 3=NE, 4=ENE, etc. The next digit is a letter which represents the radial distance from the reference point:

S = On-site location E = 4-5 miles off-site A = 0-1 miles off-site F = 5-10 miles off-site B = 1-2 miles off-site G = 10-20 miles off-site C = 2-3 miles off-site H = >20 miles off-site D = 3-4 miles off-site The last number is the station numerical designation within each sector and zone; e.g., 1,2,3,... For example, the designation SA-WWA-3E1 would indicate a sample in the Salem and Hope Creek program (SA), consisting of well water (WWA), which had been collected in sector number 3, centered at 450 (north east) with respect to the reactor site at a radial distance of 4 to 5 miles off-site, (therefore, radial distance E). The number 1 indicates that this is sampling station #1 in that particular sector.
